FiNSTA’14


The Sai educational institutions have been established not merely to enable students to earn a living but to make them acquire good traits, lead ideal lives, and give them ethical, moral and spiritual strength.

I have established them with a view to inculcate love and teach good qualities to students. They will learn here humility, discipline and faith. I have established these institutions to impart spiritual education as a main component and worldly education as a secondary one. Education should enable one to cultivate good qualities, character and devotion. The teaching of the university curricula is only the means employed for the end, namely; spiritual uplift, self-discovery and social service through love and detachment.

This will be a Gurukula - a place where teachers and taught will grow together in love and wisdom- and like the ancient system of education, it will develop in its students a broad outlook and promote virtues and morals, which serve to foster noble ideals in society.

This institute will be a temple of learning where youth are shaped into self- reliant, contented and enterprising heroes of action and self-sacrifice, for the purpose of serving humanity.

-Sri Sathya Sai Baba

1 State-of-the-arts science and applications of carbon nanotubes toward designsafe nano

Morinobu Endo††Shinshu Univeristy, Japan

Plenary Session E1 [ 22-Dec 10:00 ]

Carbon nanotubes (CNTs) have attracted lots from various fields of science and technology be-cause of the innovative physical and chemical properties due to their intrinsic nano-sized and one-dimensional natures. Various kinds of carbon nanotubes have been obtained commercially by themost common process of catalytic chemical vapour deposition, and have been used widely. For suc-cessful further developments of CNTs, the toxicity and safety of carbon nanotubes are the most im-portant key issue. By sharing the all informations on risks with all the stakeholders, we are able toprove the carbon nanotubes for green and safe innovation. For CNTs, the responsible productionsand uses from occupational to environmental health issues as well as the designing the safe carbonnanotubes are important as a 21st centurys material. The promissing safe nanostructured CNTs willbe shown.

3 Nanostructure thermoelectric materials, their manipulation, study,and applica-tions for renewable energy

Yang-yuan Chen††Institute of Physics, Academia Sinica, Nankang, Taipei, Taiwan, 11529, Taiwan

Plenary Session C1 [ 21-Dec 10:15 ]

In order to achieve the application of TE materials for renewable energy, the high heat-electricityconversion efficiency, i.e. the high figure of merit (ZT) for TE materials, is required. In this report, I willpresent a couple of strategies to engineer high ZT thermoelectric material, these include the manip-ulation of size, phase and electronic structure of TE materials. The creation of interface boundaries innanocomposites is employed to increase the phonon scattering and accordingly reduce their thermalconductivity. For high zT TE materials, to exclude the low zT impurity phases is crucial to achievehigh performance TE materials, thus the phase stability such as by doping and heat treatment toobtain pure phase of TE materials will be discussed. The electronic band structure modification bycarrier concentration manipulation to obtain high ZT material is also an alternative method. The TEproperty measurements including Seebeck coefficient, thermoconductivity by commercial facilitiesand home- made Herman system will be demonstrated. The geometric size effects on thermoelectricproperties of a single nanowire are investigated using three omega method (3ω). Keywords: high ZTTE materials, electronic structure, thermal conductivity, and Herman method.

4 Nanomaterials for energy and water management:The Indian perspectiveTata Narasinga Rao††ARCI, India

Plenary Session B1 [ 20-Dec 15:15 ]

Energy and water management mean conservation and effective utilization of the resources. Forexample, electric vehicles (EV) based on Li-ion batteries are considered to be the best option to reducethe oil consumption in transport sector, as India largely depends on the import of crude oil to meetthe energy demand. Nanocrystalline electrode materials offer shorter diffusion lengths for Li ions inbatteries and thus enable fast charging and discharging on demand, which makes EVs compete withfuel-based vehicles in terms of driving range, speed and charging time. In the case of water sector,it is known that 30% of Indian population lives in urban areas, and 15-20% of all water consumedat home is mainly used for laundry purpose and water consumption is highly alarming. Nanotextileswith water-repellent and self-cleaning functions allow minimizing the water usage in washing. For ex-ample, fabrics modified with photocatalytic TiO2 nanoparticles decompose under sunlight any organicstains sticking on it and makes it self-cleaning thus making it water-free washing. Present talk focuseson nanomaterials-based Li-ion battery and self-cleaning photocatalysis technologies to address suchaspects related to energy and water management with special emphasis on the work being carriedout at ARCI.

5 Recombinant metal sensing bioluminescent bacteria novel tools in nanotoxicol-ogy of metal containing nanomaterials



Toxicity of metal-containing nanomaterials (NMs) remarkably depends on their solubilisation, i.e.shedding and speciation of the toxic metal ions. Since past ten years recombinant metal sensingbacteria mostly based on Escherichia coli as a host bacterium and luciferase as a reporter proteinhave been developed and refined in our Laboratory, to be used in nanotoxicology. These bacteria aregenetically modified to respond dose-dependent-wise to bioavailable metal ions that have entered thebacterial cell, i.e. crossed the biological membrane, by increased bioluminescence. Depending on themetal-sensing element introduced, these bacteria can sense bioavailable metals at very low subtoxicconcentrations. The sensitivity threshold depends on the toxicity of metal and is usually below mg/L.In the context of nanotoxicology we have used mostly Zn-, Cu- and Ag-sensing E. coli bacteria (i)to quantify dissolved and bioavailable fraction of ZnO and CuO (nano versus bulk), uncoated anddifferently coated Ag NPs and (ii) to evaluate solubility, speciation, bioavailability and toxicity of ZnO,CuO and nAg in natural river waters with different content of dissolved organics. Most recently weapplied E. coli Ag-sensor to elucidate the effect of the particle size of 10-80 nm Ag NPs on the toxiceffect to an array of (eco)toxicological test organisms and showed that smaller NPs were more toxicdue to higher solubility. We conclude that metal-sensing bacteria are powerful tools in nanotoxicologyof metal-containing NMs.

6 Nanoparticle-Immune Interactions from a Biophysical to Physiological Perspec-tive

Concern about the use of engineered nanomaterials (ENMs) has increased significantly in recentyears due to potentially hazardous impacts on human health. Upon introduction into biological en-vironments ENMs associate proteins, lipids and macromolecules forming a ’biocorona’. The ENM-biocorona alters the ENM-cell interface resulting in modified uptake, activity, clearance and toxic-ity. Here we characterized the formation of an ENM-biocorona on silver nanoparticles and carbonnanotubes and examined its alterations in cellular interactions and protein structure and function.Secondly, we have examined the involvement of mast cells and allergic inflammation in pulmonary,cardiovascular and in vitro responses to ENMs. We have established that certain ENMs are capableof inducing mast cell degranulation leading to allergic immune responses. For example, AgNPs in-duce mast cell degranulation that is dependent upon ENM interaction with scavenger receptor classB (SR-BI). For in vivo studies, we have utilized multiple knock-out and transgenic mouse models toassess allergic inflammation following ENM exposure. We have found that mice with normal mast cellpopulations exhibit significant ENM directed inflammation. In contrast, these inflammatory responsesto ENMs were not observed in mice deficient in mast cells or key inflammatory mediators (e.g. IL-33and SR-BI). Our findings establish that biocorona formation, mast cells, IL-33 and SR-BI all contributeto adverse immune responses to ENMs giving insight into a unique mechanism of action.

Nanotechnology is now creating a growing sense of excitement in the life sciences especiallybiomedical devices and Biotechnology. This area of endeavor is an inter-phase between biology withengineering applications to recognize, organize and functionalize molecular materials which is ap-plicable to medicine. Fungal mediated silver nano particles act as an antimicrobial, antibacterial,antiviral, antibiotic and antifungal agent. Thus we are very much interesting in the usage of herbbased silver nanoparticles to neutralize the HIV 1. Our studies revealed that herbal based silvernanoparticles undergo a size dependent interaction with HIV 1, with nanoparticles exclusively in therange of 1 U 10 nm attached to the virus. The exterior of the HIV 1 virus is comprised of a lipidmembrane interspersed with protruding glycoprotein knob, formed by trimers consisting of two sub-units: the gp120 surface glycoprotein subunit exposed to the exterior and the gp41 transmembraneglycoprotein subunit spans the viral membrane and connects the exterior gp120 glycoprotein withthe interior p17 matrix protein. The main function of these protruding gp120 knobs is to bind withCD4 receptor sites on host cells. The interactions of inorganic nanoparticles with biosystems are justbeginning to understand. However in order to realize the future promise of nanoscience. The facileincorporation of nanoparticles into a variety of media provides the incentive for the further researchon the interaction of nanoparticles with viruses.

In geometry, the immediate neighbors of Carbon, Boronand Nitrogen replace carbon, while Aluminium and Phosphorus, immediate neighbors of silicon, re-place its atom at the edges of SiC nanotube. The density functional theory based computations havebeen performed by using Generalized gradient approximation(GGA) as exchange correlation func-tional, parameterized with Revised Perdew, Burke and Ernzerhof (RPBE).The structural stability of thestructures has been analyzed in terms of total energy and binding energy calculation, Where negativevalue of total energy shows that all the edge passivated (8, 0) SiC nanotubes are stable supportedthrough positive binding energy. In results, the N passivated SiC nanotube is most stable amongst allthe tubes taken into consideration. In electronic properties, the pristine (8, 0) SiC nanotube showsa direct bandgap of 1.232eV, which reduces on passivation of both the edges with III and V groupelement.

Optoelectronic applications of graphene require quantitative insights into the relaxation of the hotcarriers in its conical energy - momentum space. In this talk we will discuss our recent results on op-tical pump-terahertz spectroscopy of graphene with different levels of Fermi energy and momentumrelaxation time to understand the role of intraband relaxation and secondary hot carrier generation.The magnitude and sign of photo-induced terahertz conductivity can be tuned in graphene by ap-propriate parameters. The cooling dynamics will be discussed in terms of various mechanisms. Wewill also present low frequency resonances seen in the terahertz range in reduced graphene oxide interms of energy gaps due to van Hove singularities in the density of states due to the rotation of thegraphene layers (Moire fringes).

10 Ultrafast laser-induced plasmas for nanoparticle generation: comparison withconventional chemical routes


Keynote Session D1 [ 21-Dec 13:40 ]

Recently, plasma plumes generated by ultrafast (femtosecond) laser pulses are being studied asnovel sources for synthesizing high quality, non-toxic nanoparticles (NP). Detailed characterization ofthe plasma is required for efficient NP generation. Here we produce plasmas by ablating high puritysolid targets using short (7 ns, 1064 nm) and ultrafast (100 fs, 800 nm) laser pulses, and investigatetheir dynamics by the optical time of flight (OTOF) technique. In general, at lower incident fluenceslaser ablation reveals the signature of two different products forming at different times, which canbe attributed to neutral atoms and NPs respectively. At higher fluences three different products arefound to form, namely, fast atomic species, slow atomic species, and NPs. The size of the generatedNPs depends on laser pulse width and fluence. In addition to OTOF measurements, we also employedICCD plume imaging (with nanosecond resolution) to study the plume dynamics. These investigationsillustrate the influence of laser fluence, intensity, and background gas pressure on the generation of

fast atomic species from the target, which is of significance when laser plasma is used for produsinghigh quality NPs. Another interesting observation is that for certain optimized irradiation energies andambient pressures fast neutrals in fact accelerate for a short while immediately after ablation. Thisacceleration might alter the nature of the generated NPs. we have synthesized NPs by the plasmaroute from nickel, silver and copper targets, and the physical properties are compared with thoseprepared using conventional chemical routes.

11 Never-ending Surprises in Photoluminescence from semiconductor nanocrys-tals

D D Sarma††Indian Institute of Science, India


One of the most spectacular aspect of semiconductor nanocrystals has been their photolumines-cence properties, offering wide-ranging tunability of the emitted light and a high degree of quantumefficiency, not usually achievable with corresponding bulk materials; this has led to an intense in-terest in such materials, both in terms of fundamental science and technological possibilities. Thereare primarily two distinct classes of light-emitting nanocrystal materials. One class makes use ofthe band-gap emission, thereby achieving a high degree of tunability as a function of the nanocrys-tal size via the quantum confinement effect. However, this class of photoluminescence tends to bemore easily affected by surface degradation and is seriously limited in its usefulness due to severeself-absorption problems. The other route makes use of deexcitation through atomic-like levels of adopant ion via energy transfer between the host nanocrystal and the dopant site, thereby obviatingany problem of self-absorption and achieving a greater stability of the luminescence, but forgoing thetunability with the nanocrystal size. In my presentation, I shall discuss how one may go beyond theseexpected limitations of each case, making the band-gap emission intrinsically stable and dopant emis-sion tunable, through understanding the fundamental processes involved in each case, that requireshifting away from some of the dominant dogmas in the field. If time permits, I shall also touch upona third class of photoluminescing semiconductor nanosrystal systems, where the heterostructure oftwo different components controls the emission properties, giving rise to unexpected results.

Enormous progress has been achieved towards light-matter interac-tion in these plasmonics and photonic crystal structure with enhanced photon density of states (DOS).In the case of photonic crystals we studied the photonic band gap edge effects on the reduced groupvelocity and confinement of electric fields in dielectric and air media. The novel metal-dielectric pho-tonic crystal is realized by a simple chemical process by infiltration of gold nanoparticles in an inversesilica opal. The influences of the confined intense fields are probed by performing the wavelengthscanned surface enhanced Raman scattering (SERS) measurements. We will also present the fieldconfinement results in the defect layers of PhC structures, where a metal-dielectric porous silicon(PS) microcavity structure is visualized by infiltrating gold nanoparticles (Au NPs) into the deep see-through nano sized pores of PS multilayer microcavity. The photon-plasmon coupling are probed byperforming the resonant and non-resonant Raman scattering experiments, by coupling the opticalfields of the cavity mode to the scattered Stokes photon mode of porous silicon at a Raman shift of500 cm−1. An enhancement in Raman signal at resonance condition is explained by photon-phononinteraction mediated through the intense plasmon fields.

A. Joy Singh††Department of Physics, S. Kula WomenŠs College, Nambol, Manipur., India

Poster P-485 [ Dec 20, 19:25-20:55 ]

ZnO nanoparticles were doped with different concentrations in PVC and made films by solutioncast method. The electrical conductivity was measured for different range of temperature and appliedfields. The conductivity versus temperatu re for different samples have been plotted and from the plotthe conductivity increases with increase of doping rate for range of temperature (313-373 K), but forlow temperature up to 313K the conductivity are almost the same. The activation energy for higherconcentration is greater than that of low concentration which shows the increase in semiconductingproperty with increase of doping.

Poster P-486 [ Dec 20, 19:25-20:55 ]

Titania (TiO2) is a very fascinating semiconductor for wide application in catalysis, dielectric ce-ramics, solar cells and optoelectronic devices. The polymorph of titania are formed by the differentinterconnections of TiO6 octahedral. The anatase phase is more important due to its surface reactiv-ity. The surface defects, oxygen vacancies and the reconstruction of the surface strongly influencethe physical and chemical properties of titania. The large surface area and the quantum size effectof the nanoparticles result in improved performance of the materials. The thermodynamic phasestability of the nanocrystalline titania as a function of particle morphology and radius has been exten-sively studied. The effective surface area of preferred surface facets of TiO2 nanoparticles determinethe suitability for particular application. Complex impedance and dielectric permittivity of titania-polypyrrole nanocomposites have been investigated as a function of frequency and temperature atdifferent compositions. A very large dielectric constant of about 13000 at room temperature has beenobserved.

Poster SP-715 [ Dec 21, 19:20-20:50 ]

Iron disulphide (FeS2) is considered as a potential solar absorber material due to several factors.These include more abundancy and less toxicity of the elements involved, suitable energy band gap(0.95 eV) with high optical absoprtion coefficient and sufficiently long minority carrier diffusion lengthto produce short circuit currents > 30 mA. In this work a simple wet chemical process, chemical bathdeposition was used to synthesize FeS2 films using iron sulphate and thiourea as precursors. Ammoniain combination with EDTA was used as novel complexing agent to form the layers for the first time.The films were deposited using different bath temperautres (Tb) that vary in the range, 50-70o C,

keeping the other deposition parameters constant. The analysis revealed that the bath temperaturehad a significant effect on the behavior of FeS2 films. Composition analysis of the layers revealed thepresence of Fe and S apart from the other minor impurities. The XRD spectra revealed the presence ofmixed phases, marcasite and pyrite of FeS2 structures at lower bath temperatures that changed intopurepyrite phase (2 0 0) plane at Tb=70o C . This behavior is supported by the Raman measurements.All the grown FeS2 films had a homogeneous and uniform surface morphology. All the films had opticalabsorption coefficient >104 cm−1 and the evaluated Eg varied in the range, 1.47-1.16 eV with increaseof Tb. The FTIR spectra indicated the presence of -OH, C-H and S-O stretching vibration modes.

18 Effect of sulphur doping on the thermoelectric properties of tin selenide - Afirst principles study


Poster SP-716 [ Dec 21, 19:20-20:50 ]

In this work, we present the thermoelectric properties of tin selenide (SnSe) and sulphur doped tinselenide (SnSe(1−x)Sx, x=0.12 and 0.25) obtained using the first principles calculations. We obatainedthe electronic band structure using the FP-LAPW method within the sphere of the density functionaltheory. Thermoelectric properties were calulated using BoltzTraP code using the constant relaxationtime approximation at three different temperatures - 300, 600, and 800 K. Seebeck coefficient (S) wasfound to decrease with increasing temperature in all samples, the highest being 1720 microV/K at 300K for SnS0.75S0.25 . Electrical conductivity (sigma/tau) was almost constant in the entire temperaturerange, the highest value was found to be 7 x 1020/omega m s for n-type SnSe. On the otherhand ther-mal conductivity (kappa/tau) increased with increasing temperature for all samples with a maximumvalue of 14 x 1015W/m K s at 800 K for SnSe. Sulphur doped samples showed enhanced seebeck co-efficient, decreased thermal conductivity and decreased electrical conductivity at all temperatures.At 300 K, S increased from 1500 microV/K (for SnSe) to 1720 microV/K (for SnSe0.75S0.25), thermalconductivity decreased from 5 x 1015 W/m K s (SnSe) to 3 x 1015 W/m K s, electrical conductivitydecreased from 7 x 1020 /omega m s to 5 x 1020 /omega m s. These calculations show that sulphurdoped tin selenide exhibit better thermoelectric properties than undoped tin selenide.

19 *Ultrafast Photo-excitation dynamics in Organo-Lead Tri-halide Perovskites: aPhotophysical perspective for Optoelectronics


Session F1 [ 22-Dec 14:10 ]

Excitonic solar cells, within which bound electron-hole pairs play a central role in energy har-vesting, have represented a hot field of research over the last two decades due to the compellingprospect of low cost solar energy. However, in such cells exciton dissociation and charge collectionoccurs with significant losses in energy, essentially due to poor charge screening. Organi-lead halideperovskites (CH3Nh3PbI3−xClx) seems to bear the premise for overcoming such limitations and theyare now attracting tremendous interest to realize high performance solar cells. Here we employ tran-sient absorption spectroscopy to reveal the photo-excitation dynamics in these novel materials. Weexplore the influence of material morphology, temperature and excitation density to understand thephoto-physical processes involved. We find that at room temperature, the dynamics are dominated

Our studies alsoreveal an ultrafast (< 200 fs) photo-induced change in the dielectric constant, that can be attributedto the re-orientation of the organic cation within the lattice. A direct correlation between the crys-tal dimension and dielectric constant (and subsequently the optical absorption and dynamics) is alsodiscussed. The novel optical properties of these materials presented here can provide an impetus fortheir further application in many optoelectronic devices.

Zinc Aluminum Oxide (ZAO) thin films were deposited on glass substrates by DC reactive mag-netron sputtering technique at different sputtering powers varied from 85 to 125 W. XRD patternsof ZAO films show (0 0 2) preferred orientation with c-axis perpendicular perpendicular to substrate.From XRD data crystallite size, lattice constants and compressive stress of the films were determined.The surface morphology and topography of the films are studied using FESEM and AFM. The imageprocessing of AFM data provides the quantitative information on nanostructured thin films. Statis-tics on group of particles are measured through image analysis and data processing includes parti-cle counts, particle size distribution, surface area distribution and volume distribution. The averageroughness, rms roughness, ten-point mean height roughness, surface skewness and surface kurto-sis parameters are used to analyze the surface topography of the films. The minimum resisitivity of1.67 x 10−4 ohm.cm and an optical transmittance of 92% is obtained for the film deposited at 115W. The optical band gap of the films increased from 3.43 to 3.60 eV with the increase of sputteringpower from 85 to 125 W. The results acheived for ZAO thin films exhibit a good surface roughness forlight scattering and low resistivity which will be benificial for the development of high performancetransparent electrodes for photovoltaic devices.

25 Experimental studies on topological properties of carbon nanotube networksin buckypapers

Bhanu K Kamapantula†, Ramakrishna Podila, Preetam Ghosh†Virginia, United States of America

Poster SP-719 [ Dec 21, 19:20-20:50 ]

Carbon Nanotubes (CNTs) exhibit unique electronic, optical, and mechanical properties due to thequantum confinement of electrons. While multi-walled CNTs themselves are highly conducting, theirnetworks often result in semiconducting/insulating properties depending upon the interjunction resis-tance and the number of connections in the percolation path. Networks of CNTs have been proposedfor use in thin-film field effect transistors due to the fact that their resistance can be easily controlledby an external gate voltage. Furthermore, networks of CNTs (in the form of buckypapers) are alsowidely used for energy storage in supercapacitors and electrochemical sensors. Despite the highpotential of CNT networks, there is little or no knowledge their fundamental nature. Are CNT net-works random or scale-free? We hypothesize that the performance of CNT networks can be improvedthrough rational design of scale-free/random networks. To validate such a hypothesis, we fabricatedCNT networks on Si/SiO2 susbtrates, measured their electrical resistance, and studied the percolatingpaths using two-probe measurements and scanning electron microscopy. For modeling these results,we generated CNT networks as per Erdos-Renyi model and used Moore-Penrose pseudoinverse of theLaplacian matrix to detemine the nature of CNT networks on Si/SiO2 susbtrates and CNT buckypapers.

Session E1 [ 22-Dec 11:00 ]

Field-emission displays(FEDs) are considered to substitute the presently dominant liquid crystalsbecause of their low cost and high performances. However, improvement in consistent and efficientcold cathode materials for electron field emitters is one of the major concerns in FED technology.Different nanostructured materials such as semiconducting nanowires or nanotubes, carbon nan-otubes(CNTs), diamond film have been demonstrated to show low turn-on voltages and high currentdensity values, making them suitable for cold cathode emitter applications. In this talk we reportsubstantial enhancement of electron field emission(EFE) properties of the Fe coated/post-annealednanocrystalline diamond films and hydrogen plasma treated diamond nanowire(DNW) films. EFEproperties of ultrananocrystalline diamond films(UNCD) were improved by nitrogen(N) ion implan-tation or post-annealing processes. Fe-coating and subsequent post-annealing is seen to enhance the

EFE properties of diamond films. Scanning tunneling spectroscopy in current imaging tunneling spec-troscopy mode clearly shows significant increase in local emission sites in 10 min hydrogen plasmatreated diamond nanowire (DNW10) films as compared to the pristine films that is ascribed to the for-mation of graphitic phase around the DNWs due to the hydrogen plasma treatment process. The EFEprocess of DNW10 films can be turned on at a low field of 4.2 V/µm and achieved a high EFE currentdensity of 5.1 mA/cm2 at an applied field of 8.5 V/µm. The highly conducting hydrogen plasma-treated DNW films with enhanced EFE characteristics may open up a pathway for the development ofhigh-definition flat panel displays or plasma devices.

Poster P-490 [ Dec 20, 19:25-20:55 ]

The main focus for promising solar energy technolgy is direct production of solar fuels using sun-light. Sunlight can be used to convert photon energy into the energy of chemical bonds with electro-chemical reactions by using a photocaalyst, such as low energy water into high energy hydrogen. Hy-drgen production under solar irradiation was carried out using aqueous-alcoholic solution containingTiO2 nanotubes and CuO/TiO2 nanocomposite photcatalysts. The mono and di-hydric alcohol in waterwas used as hole scavengers and their effect for the production of hydrogen is evaluated. The ex-perimental parameters viz., amount of copper in CuO/TiO2 nanocomposites,volume of ethylene glycolwere optimized for highest rate of hydrogen prduction. The 1.5 CuO/TiO2 nanotube composites (Cu-TNT) showed multi-fold enhancement in photocatalytic acivity than that of calcined TiO2 nanotubes(TNT) and commercial TiO2 nanoparticles (TP) as well. The synthesized nanocomposite catalyst thusefficiently able to absorb UV-visible part of the light for solar spectrum, less recombination of chargecarriers and enhanced surface - interface reactions results in higher activity. The higher catalytic ac-tivity is evidenced by catalyst characterization results, where 1.5 CuO/TiO2 nanocomposites exhibitingbi-crystalline (anatae-rutile) structure. one dimensional in morphology and in-situ transformation ofsurface interacted CuO to Cu2O leading to more quantum of visible light absorption. The possiblemechanism for the higher photocatalytic activity on 1.5 CuO/TiO2 nanotube under solar irradiation isproposed.

EFE properties of diamond films. Scanning tunneling spectroscopy in current imaging tunneling spec-troscopy mode clearly shows significant increase in local emission sites in 10 min hydrogen plasmatreated diamond nanowire (DNW10) films as compared to the pristine films that is ascribed to the for-mation of graphitic phase around the DNWs due to the hydrogen plasma treatment process. The EFEprocess of DNW10 films can be turned on at a low field of 4.2 V/µm and achieved a high EFE currentdensity of 5.1 mA/cm2 at an applied field of 8.5 V/µm. The highly conducting hydrogen plasma-treated DNW films with enhanced EFE characteristics may open up a pathway for the development ofhigh-definition flat panel displays or plasma devices.

Poster P-490 [ Dec 20, 19:25-20:55 ]

The main focus for promising solar energy technolgy is direct production of solar fuels using sun-light. Sunlight can be used to convert photon energy into the energy of chemical bonds with electro-chemical reactions by using a photocaalyst, such as low energy water into high energy hydrogen. Hy-drgen production under solar irradiation was carried out using aqueous-alcoholic solution containingTiO2 nanotubes and CuO/TiO2 nanocomposite photcatalysts. The mono and di-hydric alcohol in waterwas used as hole scavengers and their effect for the production of hydrogen is evaluated. The ex-perimental parameters viz., amount of copper in CuO/TiO2 nanocomposites,volume of ethylene glycolwere optimized for highest rate of hydrogen prduction. The 1.5 CuO/TiO2 nanotube composites (Cu-TNT) showed multi-fold enhancement in photocatalytic acivity than that of calcined TiO2 nanotubes(TNT) and commercial TiO2 nanoparticles (TP) as well. The synthesized nanocomposite catalyst thusefficiently able to absorb UV-visible part of the light for solar spectrum, less recombination of chargecarriers and enhanced surface - interface reactions results in higher activity. The higher catalytic ac-tivity is evidenced by catalyst characterization results, where 1.5 CuO/TiO2 nanocomposites exhibitingbi-crystalline (anatae-rutile) structure. one dimensional in morphology and in-situ transformation ofsurface interacted CuO to Cu2O leading to more quantum of visible light absorption. The possiblemechanism for the higher photocatalytic activity on 1.5 CuO/TiO2 nanotube under solar irradiation isproposed.

Cooperation between different active sites (e.g. an acid and a base) on the surface of a solidcatalyst is one of the most desired characteristics of a heterogeneous catalyst for green synthesisapplications. This property is inspired from natural enzymes and can significantly contribute to theenergy economy by reducing the number of workup steps during a synthesis reaction. Cooperativeheterogeneous catalysts may produce effects that are difficult to obtain by using a combination oftwo different mono-functional catalysts (homo or hetergeneous) where, neutralization of the activesites may result in the loss of catalytic activity. In this work, we are reporting for the first time, thecooperative catalytic activity of FeOOH nanostructures for deacetalyzation-nitro aldol condensationreaction. Different polymorphs of FeOOH also showed different selectivity.

Graphene due to its high surface area and superior conductivity has attracted wide attention fromboth industrial and scientific communties. We chose graphene as a substrate for metal nanoparticledeposition for fuel cell applications. There are many chemical routes for fabrication of metal-graphenecomposites, but they have an inherent disadvantage of low performance due to the usage of surfac-tants, that adsorb on their surface. Here we present a design for one pot synthesis of gold nanopar-ticles and simultaneous deposition on graphene with laser ablation of gold strip and functionalizedgraphene. In this process there are two natural advantages, the nanaoparticles are synthesized with-out any srufactants, therefore they are pristine and subsequent impregnation on graphene is linkerfree. These materials are well characterized with electron microscopy to find their morphology andspectroscopic techniques like Raman, UV-Vis. for functionality. This gold nanopartilces decoratedgraphene composite has been tested for its electrocatalytic oxidation of alcohols, for alkaline fuel cellapplications. An electrode made of this composite showed good stability for more than 200 cycles ofoperation and reported a low onset potential of 100 mV more negative, an important factor for directethanol fuel cells. In conclusion, we were succesful in designing, laser mediated synthesis of metalnanoparticle-graphene composite in a single step. We were also confident to show the superiority ofhe composite by testing its activity for electro-oxidation of other alcohols.

Energy from renewable resorces is of great importance for societal needs and industrial devel-opments. Hydrogen is a well known energy carrier and it generates electricity in combination withOxygen in fuel cells. The clean and sustainable process of Hydrogen production is of great demand.Photocatalytic water splitting from renewable resources like solar light is efficent way for cleanerhydrogen(H2) production which leads to sustainable development. Many semiconductor materialshave been investigated as photocatalysts for water splitting. TiO2 is one of the most studied phto-catalyst for water splitting into H2 and O2 due to its high chemical stability towards photocorrosion,non toxic, low cost, and better activity. Recently TiO2 based composite photocatalyst materials havebeen attracting for effecient hydrogen production. The efficiency of photocatalysts is limited due topoor surface - interface transfer of charge carriers during photocatalytic process. Hence it is urgentneed to develop highly effecient photocatalysts for H2 generation using earth abundant chemicals.Titanate nanotubes were synthesized by simple hydrothermal method. The Titania nanotubes (TiNT)were formed after calcination and crystallanity also improved. The NiO/Titania nanotube compos-ites(NiO/TiNT) were prepared using Nickel nitrate precursor by impregnation method.

In the present investigation, we report the synthesis of Lead Telluride (PbTe) nanocubes by chemi-cal reduction method followed by spark plasma sintering. As-synthesized nanocubes and sintered pel-lets were characterized by X-Ray Diffraction (XRD), High Resolution Transmission Electron Microscope(HRTEM). XRD data confirmed the cubic phase and peak broadening was observed in nanostructuresdue to nano-sized effects in both cases. Distribution of grain size, nanocrystalline nature of PbTe fur-ther conformed by HRTEM. PbTe nanocubes exhibited a high thermo power is 420 tV around 400 K.Interestingly significant decrease in thermal conductivity was attributed to post sintering nanocubeseffectively scattered various length scales of phonons effectively and thus intern increase in ZT. Thefigure of merit (ZT) was observed to be 0.45 at 300K and 0.38 at 400K.

organoboron units such as alkylborane, boric ester, lithium borate, boron stabilized anion and so forth.Structure-property relationships were studied with respect to ionic conductivity, lithium transferencenumber, Vogel-Fulcher-Tammann parameters. The electrolytes bearing highly Lewis acidic alkylbo-rane units showed higher lithium transference number due to efficient anion trapping. In these sys-tems, organoboron units not only trap anion but also promote further dissociation of lithium salts viaboron-anion interaction. Further, we have also studied preparation of various organic-inorganic hy-brid ion-gel electrolytes. A series of borosilicate based ion-gel electrolytes prepared by in-situ sol-gelmethod in the presence of low viscous ionic liquids showed high thermal stability of up to 400oC withhigh ionic conductivity. As an alternative method for organic-inorganic hybrid ion-gels, we have alsoexamined condensation of cellulose with boric acid or hydroborane in ionic liquids, which was alsoproved to be an effective method.

Efficiency of energy converting systems like Li-Air battery and fuel cells predominantly dependson oxygen reduction reaction(ORR) which occurs at cathode. Due to sluggishness of its kinetics, ORRis the rate determining step. The key factors that determine kinetics are surface area of carbon sup-port, ability to support the catalyst, pore size, charge-transfer resistance and durability of carbon.Usually, graphite and carbon blacks such as acetylene black (AB) are used as cathode materials.Even though graphite has better conductivity, AB overpowers graphite in having properties like lowresistivity in the presence of electrolyte, active electrode material by itself, absorbs and retains signif-icant volume of electrolyte, high surface area and economical. Owing to these properties, AB can bea promising material for its use as active electrode material. ’Durability’ The major issue for AB’s non-applicability has been answered in this work by surface modification. In brief, AB was functionalizedand exfoliated (FAB) using a facile novel single pot method. FAB was decorated with 8%, 10% and40% Pt-nanoparticles of 5-8nm size. Along with impressive ORR activity, the durability of the materialhas been tremendously increased due to protective decoration with Pt-nanoparticles. In comparison,coulombic efficiency of 10% Pt-FAB is nearly 60% higher than that of commercially available Pt/C for100 cycles of ORR. Hence Pt-FAB is an efficient cathode material which finds its application in Li-Airbattery and fuel cells.

However, the large band gap (3.2 eV) has always been thehurdle stone in tapping TiO2 to its maximum. Mixed oxide composite nanotubes show a unique pho-ton energy retention feature i.e., the photon to electrical energy conversion process does not ceaseimmediately after curbing the photon influx but stops gradually. This feature in TiO2+WOx nanotubeshas not been studied in depth. Further, the use of dye sensitized electrode in photoelectrochemi-cal (PEC) water splitting is a new area of research with significant potential for the development ofhigh performance solar fuel systems. Herein, TiO2+WOx nanotubes were synthesized and used assubstrate for dye sensitized photoelectrochemical water splitting. The dye used in this study wasa curcumin based ruthinium complex, which was synthesized indegenously. The synthesized nan-otubes and oganometallic dye were characterized using conventional analytical methods. The elec-trochemical impedance measurements immediately before and after photoirradiation demonstratedremarkably slow increase in the charge transfer resistance indicating good energy retention propertyin the prepared electrode.

53 *Impact of Molecular Charge-Transfer States on Photocurrent Generation inSolid State Dye-Sensitized Solar Cells Employing Low-Band-Gap Dyes

The role of intermolecular charge transfer (CT) states in solid-state dye sensitized solar cells em-ploying a perylene dye and metal-oxide nanostructured electrodes are investigated comprehensivelyemploying (a) ultrafast transient absorption, (b) transient photoluminescence and (c) optical pump-THz probe spectroscopy techniques. Here we show that the presence of a molecular excited statewith a strong charge-transfer character may be critical for charge generation when the total energyof the photoexcitation is too low to intercept accepting states in the TiO2 photoanode. Though holetransfer to the 2,2′,7,7′-tetrakis(N,N-di-pmethoxyphenylamine)-9,9′-spirobifluorene (Spiro-OMeTAD)can be very fast, an electron – hole pair is likely to form at the organic interface, resulting in a possi-ble trap like excitation. This leads to poor photocurrent generation in the solid state DSSC (ss-DSSC)device. Combining the information obtained from the three complementary ultrafast spectroscopytechniques mentioned above, we find that the molecular exciton is stabilized in a low-energy CT statethrough efficient intramolecular electron transfer and if the metal oxide presents a significant energybarrier, the photoexcited state may remain trapped at the organic interface, though hole transferfrom the dye to the Spiro-OMeTAD happens efficiently. This will lead to a loss in charge generationand hence low photo-current. We demonstrate that it is possible to overcome this issue by fabricat-ing SnO2 -based ss-DSSC and performing similar spectroscopic analysis. We corroborate the aboveobservation by fabricating and testing devices with both TiO2 and SnO2 photoanodes.

A SWCNTs (single-walled carbon nanotube)/ (Pb, Zn)-phosphate glass composite has been synthe-sized and the results of studies on optical, light induced ESR, electronic and optoelectronic propertiesof the composite have been reported. Absorption spectrum of SWCNTs in the composite has beenfound to be quite different from that of its film and is attributed to the host related internal stress in-duced conformational deformations and subsequent band structure modulation of the SWCNTs of thecomposite to the quasi-metallic type. From the UV-Vis light-induced ESR spectrum of the composite,it was found that a charge separation took place in that medium which was due to creation of Pb+3

− holes, releasing electrons from the interstitial Pb+2 − sites and capture of those photo-generatedelectrons by the SWCNTs. From the studies of electronic conduction properties it has been shownthat incorporation of SWCNTs in the glass gives an optically transparent material which is hundredthousand times more conducting than the host glass. The composite thus shows the prospect of useas efficient photo-current convertor and a transparent electrode in different practical devices.

Inthis respect, production of hydrogen through splitting of water using solar energy in a photoelectro-chemical(PEC) cell is one of the most environment friendly method. The selection of the photoanodematerial is crucial for high efficiency PEC cell. Hematite has been proven as better photoelectrode forhydrogen generation, but with limited efficiency. Poor charge transport in hematite can be overcomeby using GNP (Grpahene Nanoplates) and CNT(Carbon Nanotubes)as conducting scaffold facilitat-ing carrier transport from semiconductor to ITO substrate. In this research, sol-gel of hematite wasprepared using 2 methoxy ethanol with ferric nitrate. 0.2 wt% GNP and CNT were added to aboveprepared gel during sonication. 0.2 wt% GNP modified Hematite (4H:0.2GNP) and 0.2 wt% CNT modi-fied hematite (4H:0.2CNT) composite films thus obtained were studied as photoelectrode in PEC cell.XRD, UV-Vis Spectroscopy, RAMAN and SEM techniques were used to characterize the material andto analyse PEC data. Both GNP and CNT modified hematite films exhibited enhanced photoresponse,which is attributed to efficient facilitation of carriers from semiconductor to ITO substrate and redshift in UV-Vis spectra with respect to pristine hematite sample. Highest photocurrent density of 2.5mA/cm2 and 0.76 mA/cm2 at 0.75 V/SCE was observed for 4H:0.2GNP and 4H:0.2CNT respectively.

automata (QCA) is transitor less, most promising nanotechnology that can be used to build nano-circuit. In QCA information is stored based on the polarization of the cell and massage is passedwithout inter connecting wire like in traditional system. The conventional computer is irreversibleone. As an example for binary AND gate when inputs are (1,0) or (0,1) we get ’0’ at the output andthe bit ’1’ destroyed. A single bit lost generates heat energy kTln2, where k is the Boltzmann constantand T is the absolute tempertaure. A possible solution is reversible computing, where no bit is lostduring computation. Hence logically reversible circuit can consume less energy than any conven-tional circuit. In this paper the design of some QCA based reversible logic circuits such as Fredkingate, modified fredkin gate etc are proposed, also simulation of proposed circuits are perfomed usingQCA designer-2.0.3.

Functional ’hybrid’ materials based on combinations of organic molecules and inorganic nanopar-ticles open the possibility to modify the optical and charge transport properties of the inorganic com-ponent by chemical bridging with the organic functional moiety. Moreover, such hybrid systems allowthe assembly of the two components into an ordered supramolecular structure with a simple process.Among the several techniques known for the formation of the hybrid NC-organic molecule material,the layer by layer (LBL) self-assembling technique offers several advantages over other solution-based techniques for the achievement of efficient charge transport in thin films. This method leadsto densely packed layers with good surface regularity, also featuring really small interparticle dis-tances.

Poster P-505 [ Dec 20, 19:25-20:55 ]

Realizing the importance of physical properties at continental region in the air mass pathways ontothe semi-arid region, extensive measurements of aerosol physicalproperties were made at Anantapur(14.620N, 77.650E), occupying the second place to Rajasthan. Spectral aerosol optical depth (AOD)measurements are estimated using Multi-wavelength solar radiometer (MWR). The sectral and tempo-ral variations of AODs areinvestigated by analyzing the data using the Langley techniqeu. AOD varieswith time of the day, month of the year and seasons. AOD is higher in summer season (0.41+0.2)and smallest during winter season (0.23+0.09) respectively. The lower values of AOD during winterarise due to the low land temperature, which results in the weak production soil derived dust. Largervalues of the AODs around shorter wavelengths indicate the abundance of small sied particles. ToCharacterize AODs, the Angstrom parameters alpha and beta were used. In the present study alphavalues are varying between 1.03-1.19. Alpha is positive and indicating a relatively high ratio of smallto large particles and also higher content of anthropogenic aerosols. The mean beta values werevarying between 0.11-0.23 during the study period. The results show significant differences in thevalues of beta for the summer and winter seaasons.

60 Spectral and temporal characteristics of aerosol optical depth over Anantapur,a semi-arid region in India


Poster P-505 [ Dec 20, 19:25-20:55 ]

Realizing the importance of physical properties at continental region in the air mass pathways ontothe semi-arid region, extensive measurements of aerosol physicalproperties were made at Anantapur(14.620N, 77.650E), occupying the second place to Rajasthan. Spectral aerosol optical depth (AOD)measurements are estimated using Multi-wavelength solar radiometer (MWR). The sectral and tempo-ral variations of AODs areinvestigated by analyzing the data using the Langley techniqeu. AOD varieswith time of the day, month of the year and seasons. AOD is higher in summer season (0.41+0.2)and smallest during winter season (0.23+0.09) respectively. The lower values of AOD during winterarise due to the low land temperature, which results in the weak production soil derived dust. Largervalues of the AODs around shorter wavelengths indicate the abundance of small sied particles. ToCharacterize AODs, the Angstrom parameters alpha and beta were used. In the present study alphavalues are varying between 1.03-1.19. Alpha is positive and indicating a relatively high ratio of smallto large particles and also higher content of anthropogenic aerosols. The mean beta values werevarying between 0.11-0.23 during the study period. The results show significant differences in thevalues of beta for the summer and winter seaasons.

Organic pollutants (dyes) are widely used in many industries such as textiles and food and theyare very harmful to human being and environment. Photocatalysis is a clean, attractive, less ex-pensive, and energy intensive process for waste water treatment since complete mineralization oftoxic wastes take place. In the present study, we have synthesized novel nanostructured TiO2 (TiO2

NSs) through hydrothermal method and the size and morphology of TiO2 nanostructures (-nanocubes,-nanorods) were controlled by changing the various parameters such as concentrations of Ti precur-sor, solvents and reaction temperatures. TiO2 NSs were studied for their structural, morphological,thermal and crystallographic properties, and further utilized them as photocatalysts for an environ-mental remediation of organic pollutants. Photocatalytic properties of TiO2 NSs were investigatedfor the photodegradation of organic pollutants such as methyl orange (MO) and methylene blue (MB)under visible light irradiation. The visible-light photocatalytic degradation of these organic dyes wasmonitored using UV-visible spectroscopy.

TiO2 has emerged as a promising photo-catalyst because of its robust chemical stability,relativelylow production costs and non-toxicity.However, as TiO2 is a wide band gap semiconductor, it is notresponsive to visible sunlight.Doping with transition metal ions is an ecxellent strategy for visible lightactivation of TiO2.Doping also introduces interesting properties like high photostability,increased con-ductivity,enhanced magnetic properties and high oxidising ability.Doped TiO2 has also been used ascatalysts in organic reactions and in photocatalytic degradtion of organic dyes and solvents.But ex-tending such applications requires surface basedmodification of these nanoparticles.Existingmethod-ologies for surfactant based modification make use of harsh conditions like high temperature andpressure or use excess organic solvents. Hence in this study ,we synthesize surfactant modifiedFe(III) ion doped TiO2 by a modified hydrothermal method by simple furnace heating at relativelymilder calcination temperatures.We achieve surface modification by means of various surfactants,some which have not been reported previously.We use XRD technique to show successful doping andUV-VIS (Diffuse reflectance spectroscopy) to show visible light activity.

In this paper we present select applications of nanotechnology in energy and environmental appli-cations. Of particular interest are nano carbons such as carbon nanotubes (CNTs), graphene andnano silica. With appropriate surface modification with metals andmetal oxides, these materialscan provide a platform for developing excellent remediation tools that range from drinking waterdefluoridation to the removal of arsenic. A complimentary approach is their incorporation in mem-branes which exhibit greater permeation rates and higher selectivity. For example, the incorporationof CNTs in a membrane offers several advantages because there can be several alternate mecha-nisms of transport. The high aspect ratio CNTs dramatically increases the active surface area, servesas molecular transporters and increase partition coefficients; together these contribute to enhancedpermeation. The other application presented here the development of flexible energy storage devicesusing nanostructured materials based composite electrodes. This paper will discuss current effortsto develop formulations aimed at optimizing flexible zinc-carbon and alkaline batteries. Nano com-posite electrodes were fabricated and conducting polymers were added to enhance conductivity. Wereport that cathodes comprised of a CNT composites show improved conductivity, great flexibility,portability and easy manufacturability.

TNasewas captured by MAb conjugated QDs directed against it and the sensitivity was found to be 46ng/mL, which corrsponds to the amount of the TNase produced and secreted by approximately 105

S. aureus cells/ mL. The synthesis of the quantum dots and identification was well substantiated byUV- Visible (UV), Photoluminensce (PL) studies and transmission electron microscopy studies (TEM).further , the Fluorescence Resonance Energy Tranfer(FRET) based identification of the antigen by thefluorescent labelled MAb- QDs was shown by the images taken using the Epifluorescent microscopeand quenching of the photoluminence in the PL spectra.

In the last 30 years the increased interest in the optical characterization of diffusive media broughtabout a huge development in spectroscopic techniques both in the cw and time-domain regimesaimed at studying those materials where light diffusion plays a fundamental role, with a special fo-cus on biological tissues. The main advantage of the time-resolved (TR) approach is the possibilityof disentangling the absorption and diffusion (scattering) of light which are related to the chemicalcomposition and to the internal structure of the probed medium, respectively. Thus, TR spectroscopycan be used as a noninvasive diagnostic tool for in-vivo applications, providing information on thephysiology and pathology of tissues. Examples of applications are brain functional imaging, opticalmammography and breast density estimation. For possibly improving the constituents’ estimation,the wavelength range beyond 1100nm could be explored: here we expect more marked differencesamong the spectra of the main biological chromophores and more important spectral features withrespect to the wavelength region hitherto investigated (600-1100nm). So far though, this rangehas remained largely unexplored, with no broadband in-vivo studies, due to high absorption and lowscattering values which affect both the theoretical model and the detection efficiency. With the firsttime-resolved broadband system based on a supercontinuum fiber laser, a prism for wavelength se-lection and an InGaAs/InP Single-Photon Avalanche Diode sensitive up to 1700nm we performed firstin-vivo measurements on the arm and the breast of two healthy volunteers up to 1360nm.

Moxifloxacin (MXN) is a fourth generation fluoroquinolone with good aqueous solubility, better pen-etration and an improved antibacterial spectrum, particularly against resistant staphylococcus andstreptococcus pathogens, compared with older fluoroquinolones and effective drug in the treatmentof bacterial keratitis. The aim of this study was to develop the phase transition water-in-oil nanosizedemulsion (NSE) of MXN and evaluate in-vitro antibacterial potential against, Staphylococcus aureusand Escherichia coli. the pseudo-ternary phase diagram was developed using isopropyl myristate asoil phase, Tween 80 and Span 20 as surfactants and acetate buffer (pH-5) as aqueous phase. NSEswere prepared with different concentration of acetate buffer , Tween 80 and Span 20 using the oiltitration method. Physicochemical parameters (globule size, zeta potential, drug content, viscosity,refractive index and pH), and the in-vitro release of NSEs were studied. The in-vitro antibacterial ef-ficacy of NSE and the marketted drug solution were studied by UV spectrophotometric method. thedeveloped NSE showed globule size of nano range, acceptable physicochemical behaviour, good sta-bility for three months and exhibited sustained drug release in in-vitro study. Significant reduction inthe total bacterial count was observed between marketed drug solution and NSE formulation againstboth tested organisms in in-vitro antibacterial study. the developed NSE is a viable alternative to con-ventional eye drops of MXN due to its ability to enhance bioavailability through its longer precornealresidence time and ability to sustain the release of the drug.

81 Non Microscopic Differentiation of Acid-Fast from Non Acid-Fast Bacteria usinga Surface Plasmon Coupled Emission Platform



The differentiation of acid-fast from non-acid-fast bacteria in patients with suspected bacterialinfection is important to the clinical scenario of any healthcare system. The screening of acid fastbacteria, most of them from the Mycobacterium genus, from the general pool of micro-organisms inpatients is essential, as they are responsible for the onset of life threatening diseases like tuberculosisand leprosy. The conventional method for distinguishing the acid-fast bacteria in patient samples isperformed using the acid-fast staining technique, where the fluorescently stained cell wall with a highmycolic acid content, resists a decolorizing procedure on exposure to acid-alcohol treatment, therebyappearing colored, not observed in non-acid-fast bacteria. Although an established procedure, theacid-fast bacteria do not stand out very clearly in a clinical sample due to the isotropic nature offluorescence, and the staining procedure involves lengthy counter-staining procedures and the useof a fluorescence microscope that is expensive. In this study, we report the first time approachof non-microscopic screening of acid-fast bacteria, adopting the Surface Plasmon Coupled Emission(SPCE) platform, wherein the emission from a fluorophore couples to the plasmon modes of a silverthin film leading to highly directional, wavelength resolved emission with high signal to noise ratios.Using a simple spectrometer we sensitively distinguished acid-fast bacteria, eradicating the need forelaborate counterstaining procedures and expensive microscopic platforms.

Homocysteine (HC) is a known risk factor in many diseases including cardiovascular diseases,neuro-degenerative disorders, diabetes and associated complications and bone diseases. Most ofthese diseases have associated inflammation and elevated homocysteine. We focus on the im-pairment in HC pathway leading to changes in HC levels and mechanisms that trigger themanifestation of inflammation and disease. Central to our hypothesis is the association of mu-tations in enzymes involved in HC pathway and Vitamin B deficiency induced elevation of HC leadingto inhibition of the activity of Nitric Oxide Synthase which invokes ATP signaling. We have collateddata and reconstructed the pathways that lead to the precipitation of symptoms in Avascular Necro-sis of Femoral Head (AVNFH). Analysis of Data from Biophysical, biochemical and cell culture modelssupport our hypothesis. Mass spectrometric analysis shows that metabolites belonging tohomocysteine pathway are elevated and vitamin B12 and B6 are low in plasma of AVNFHpatients compared to age and gender matched control in Indian population. Vitamin B12

is found to be low in patients suffering from neurodegenerative diseases like multiplesclerosis compared to age and gender matched control. Screening for homocysteine in pop-ulations/family members of patients will help to determine the risk for pre-disposition to diseases.However, the cost of analysis of HC is high. Hence alternate methods for detection of HC have to bedeveloped. We will explore fluorescence and nano-particle coated electrode based electro-chemicaltechniques to evaluate HC levels in biological fluids.

Rapid emergence of new multi-drug resistant bacteria is posing serious threat in current clinicaland healthcare settings. Bacterial attachment onto specific mammalian cells, which is one of the fore-most events taking place in host-pathogen interactions is mediated by carbohydrate binding proteinsknown as adhesins. If these binding interactions are inhibited then the chances of getting infected aregreatly reduced. Enterotoxigenic Escherichia coli (ETEC) is responsible for causuing bloody diarrheain newborn calves, pigs and also in humans. ETEC produces different adhesin molecules that bind thebacteria onto intestinal cell-surface receptors and help in initiating infection. Adhesin molecules ofEscherichia coli K99 (EC K99) have specific binding affinity towards porcine intestinal epithelial cells.

Here, we report synthesis and characterization of iron-oxide nanoparticles (IONPs) coated withpolyethylene oxide and functionalized with sialic-acid glycoconjugate (GM3-IONPs) that exhibited highspecificity towards adhesin of EC K99. Specific bacterial adherence of EC K99 to porcine intestinal ep-ithelial cell-line IPEC-1 was observed under fluorescent microscope. Adding pre-incubated mixtureof EC K99 and GM3-IONPs to IPEC-1 cells showed significant reduction in attachment of EC K99 toIPEC-1 cells.

Copper Oxide is one of the most important transition metal oxides due to its unique properties. Itis used in various technological applications such as high critical temperature, superconductors, gassensors, in photoconductive applications and so on. Recently, it has been used as an antimicrobialagent against various pathogenic bacteria. In the present investigation, we studiedthe structural andantidermatophytic properties of copper oxide nanoparticles (CuO NPs) synthesized by precipitationtechnique. Copper sulphate was used as a precursor and sodium hydroxide, reducing agent. Scan-ning Electron Microscope showed flower shaped CuO NPs and X-ray diffraction patter (XRD) patternshowed the crystalline nature of CuO NPs. These nanoparticles were evaluated against two preva-lent species of dermatophytes viz., Trichophyton rubrum and Trichophyton mentagrophytes by usingBroth Microdilution Technique. Further, the nanoparticles activity was also compared synthetic Ser-taconazole. Although better antidermatophytic activity was exhibited by Sertaconazole as comparedto nanoparticles, yet being a synthetic Serataconazole may not be preferred as it shows differentadverse effect. However, in all the cases, T. mentagrophytes is more susceptible to extract than T.rubrum. A phylogenetic approach was applied for predicting differences in susceptibility of pathogens.Keywords: Nanoparticles, SEM, XRD, Dermatophytes, Broth Microdilution Technique etc.

The difficulty of targeted delivery of drugs to the affected tissue, organs and cells can well besolved by using magnet driven liposme. Liposome shows promise to be a smart carrier of drugsand it plays an important role in medical and pharmaceutical science. Liposome defined as nanosize spherical shaped vesicles consisting of an internal aqueous cavity surrounded by one or multipleconcentric lipidic bilayers. Liposome preparations contain encapsulated drug components and finelydispersed magnetic particles. These are useful in terms of biocompatibility, biodegradability, lowtoxicity and can control bio distribution by changing the size, liquid composition and physical char-acteristics. Furthermore, liposome can accommodate both hydrophobic and hydrophilic drugs andare able to continuously release the entrapped substrate, thus being smart drug carriers. Magnetitenanoparticles - protein hybrid has been produced by treating iron (III) / iron (II) chloride with the leafextract of the Dhatura Inoxia. The magnetite nanoparticles - protein hybrid has been trapped insidethe aqueous core of the liposome prepared by reversed phase evaporation (REV) method using oleicand linoleic acid which has been shown to be driven under magnetic field confirming the formationmagnetic liposome (ML). Chemical characterization of stealth magnetic liposome has been performedby breaking the liposome and release of magnetic nanoparticles. The presence of iron has been con-firmed by colour complex formation with KSCN and UV-Vis study using spectrophotometer Cary 60,Agilent. This magnet driven liposome using magnetite - protein hybrid can be a smart vesicles for thetargeted drug delivery.

Pharmacokinetic evaluation of citrate mediated nanosilver (CNS) was carried out in eight malemurrah calves which were randomly divided into two groups. Silver nano particles were 77.97 nm insize, irregular and spherical in shape with uniform distribution. Safety evaluation was performed be-fore the study. CNS was administered at 7.3 micro gram/Kg through intra-venous (i.v) route in Group 1and through intra-muscular (i.m) route in Group 2. Whole blood samples were collected at time inter-vals of 0, 0.067, 0.5, 1, 2, 4, 8, 12, 16, 24 and 36 hours. The samples were subjected to acid digestionin microwave sample digester for quantification of nanosilver and other metals like calcium, man-ganese, sodium and potassium by using Inductively Coupled Plasma-Optical Emission Spectroscopy.

In i.v route, the whole blood nanosilver concentrations could not be fit into any compartmental model.Hence, non-compartmental analysis was used to determine various pharmacokinetic parameters. Ini.m route, since no absorption of nanosilver was detected, pharmacokinetic analysis could not be per-formed. Nanosilver exhibited significant interactions with calcium (p<0.01) and manganese (p<0.01).Since nanosilver exhibited unpredictable pharmacokinetics, erratic redistribution, long resident time,slow elimination rates and considerable interacions with other metals, it is conluded that CNS is notsuitable for systemic administration either through i.v or i.m route.

AuNS were success-fully conjugated by non-covalent interaction with a hydrophilic photosensitizer, acridine orange (AO)through Glutathione (GSH) to achieve an improved PDT and PTT therapy. Results of the study demon-strated that AO tethered AuNS (AO@GSH-AuNS) conjugate exhibited high loading efficiency, excellentphotothermal stability with enhanced cellular uptake. The anticancer activity of AO@GSH-AuNS incombination with blue light irradiation (492 nm) was studied in in vitro using human MCF-7 breastcancer cells. Furthermore, the enhanced antitumor effect of AO@GSH-AuNS with irradiation may bedue to both the cytotoxic photodynamic effect of AO coupled nanoconjugate and photothermal ab-lation intervened by AuNS. From the results we conclude that AO@GSH-AuNS in the combined PDTand PTT based approach, could be employed as a multifunctional single nanocarrier for enhancedanticancer therapy.

In i.v route, the whole blood nanosilver concentrations could not be fit into any compartmental model.Hence, non-compartmental analysis was used to determine various pharmacokinetic parameters. Ini.m route, since no absorption of nanosilver was detected, pharmacokinetic analysis could not be per-formed. Nanosilver exhibited significant interactions with calcium (p<0.01) and manganese (p<0.01).Since nanosilver exhibited unpredictable pharmacokinetics, erratic redistribution, long resident time,slow elimination rates and considerable interacions with other metals, it is conluded that CNS is notsuitable for systemic administration either through i.v or i.m route.

presence of hydroxyl, carboxyl and carbonyl functional moieties on the surface of the CDs. These CDsexhibited fluorescence consistently at 480 nm when excited at different wavelengths. These carboxy-lated fluorescent CDs were conjugated with streptavidin by popular EDC-NHS chemistry.Fluorescencepolarization measurements confirmed the conjugation of streptavidin to CDs. The streptavidin conju-gated CDs were used as fluorescent labels for the detection of recombinant purified HIV-1 p24 antigenspiked in plasma samples. Preliminary results indicate that the use of CDs as fluorescence labels offergreat promise for sensitive detection of various antigens. They can also be easily adopted for lateralflow and microfluidics based immunoassays for point-of-care use.

We report on the design, performance assessment, and first in vivo validation of a Time-ResolvedDiffuse Optical system for broadband (600-1200 nm) assessment of absorption and scattering spectraof biological tissues for non-invasive clinical diagnostics. The system is based on a supercontinuumultrashort laser, and an electronic chain for Time-Correlated Single-Photon counting. The system wasoptimized in view of the routine use in a clinical environment with the aim to improve the spectralcoverage, and to bestow reliable results under suboptimal and quick operating conditions. As for thefirst requirement, we empowered a novel detector, developed in our Laboratories, based on SiPM(Silicon Photomultiplier), together with a more conventional SPAD (Single Photon Avalanche Photodi-ode), and InGaAs PMT (Photo Multiplier Tube) . As for the second requirement, the adopted strategywas to record continuously the instrument response function, so to compensate for unwanted tem-poral drifts or pulse shape distortions. The overall system performances were assessed on a set of16 phantoms spanning a wide range of absorption (0.1-0.4 cm-1) and reduced scatting coefficient(5-20 cm-1). Specifically, we studied Accuracy to retrieve absolute values of optical properties, Non-linearity over the clinical range of Absorption and Scattering, Noise levels for the given count rate,Stability and Reproducibility of measurements, Responsivity for each detector. The system was fi-nally enrolled in a first in vivo validation phase on healthy volunteers, carrying out non-invasive, invivo quantification of key tissue constituents (oxy- and deoxy-hemoglobin, water, lipids, collagen) andtissue micro-structure (scatterer size and density).

Poster P-525 [ Dec 20, 19:25-20:55 ]

present pGLO plasmid transformed Escherichia Coli HB 101 k12 as novel model for screeningantimicrobial agents against Beta-lactamase resistance. The transformation was effective throughheat shock. The genes coding for beta lactamase (-bla) and glow fluorescent protein (GFP) wereexpressed by growing on luria bertani (LB) agar containing ampicillin (amp) and arabinose (ara).Successful transformation and induction of antibiotic resistance against beta-lactam antibiotics wasconfirmed by observing growth in the presence of UV light. A transformation efficacy of 100 cellsper microgram of pGLO plasmid was achieved. Both untrasformed and transformed were used forscreening citrate mediated nanosilver (CNS), Aloin mediated nano silver (ANS), 11 alpha keto betaBoswellic acid (AKBA) mediated nano silver (BNS), nano Zinc Oxide (NZO), nano manganese oxide(NMO) and phytochemicals such as aloin and AKBA. Minimum inhibitory concentrations (MIC) for aloin,AKBA, NMO and NZO was performed by microplate method using para iodo nitro tetrazolium (INT)as indicator. All compounds used in the study were effective against transformed bacteria exceptMNM and AKBA. Transformed exhibited reverse cross resistance being more susceptible for aloin thanuntrasformed bacteria. ANS showed highest antibacterial activity with a MIC of 0.32 ppm followed byBNS (10.34 ppm), CNS (20.64 ppm) and NZO (34.83 ppm). In conclusion, pGLO plasmid can be usedto induce resistance against beta lactam antibiotics and the model can be used for rapid screeningfor new antibacterial agents effective against resistant bacteria.

The in vitro phototoxicity and polyplex formation of developed HB and silver nanoparticleshas been investigated on A549 cell lines and by gel retardation assay, respectively. The production ofsinglet oxygen by developed nanoparticles was qualitatively assessed by using EPR spectrometer andquantitatively by iodometric in presence of light. Results: HB and silver loaded PLGA nanoparticleswere in the size range of 200- 300 nm and have zeta potential of -7.6 to -40.6. The DSC thermo-grams of HB nanoparticles confirmed the presence of HB within the nanoparticles. The average drugencapsulation was 70.56 % and drug release from the HB nanoparticles was found to be biphasicwith an initial burst release of 4.81% in the first 8h followed by sustained release of 45.52% within 3days. The interaction between silver nanoparticles and HB was confirmed by the increase in spectralintensity of Raman spectrum. The developed HB and silver loaded PLGA nanoparticles exhibited aconcentration dependent phototoxicity and maximum phototoxicity was obtained at a concentrationof 12.5 tM when compared to HB nanoparticles and pure drug. The gel retardation assay indicatedthat the minimum concentration of HB and silver nanoparticles are only required to inhibit DNA (pp>1

These two bio-molecules are mounted on to the Gold(Au) substrate. Adenine and Thymine behave like two quantum dots over Au bed. The device isdesigned and simulated through Density Functional Theory (DFT) conjugated with Non EquilibriumGreen Function (NEGF) based first principle approach. Transconductance and threshold voltage arecalculated from this study. The study reveals ideal tunnel diode characteristics of the bio-moleculardevice in forward bias. The metallic cylindrical gate is used to wrap the central region or intrinsicregion of the bio-diode. The ab-initio method is used to designed spin polarized model of the biotunnel diode. This bio-diode exhibits its natural resonant tunnelling effect in absence of gate bias.Hence this model can be referred as Resonant Tunnel Bio Diode (RTBD). This model can be used asnano bio-sensor as it exhibits its natural switching property when no gate bias is applied. This non-gated diode conducts current in forward bias condition i.e., ’ON’ state and goes ’OFF’ when operatedin reverse bias. This model enhances transverse electronic communication between two nucleobases.

We study optical Anderson Localization in nearly pe-riodic triangular lattice structures. Our studies have shown that such nearly-periodic structures areideal candidates to observe localization of light because of the diminishing localization length withinthe band gap of the crystal. The added randomness introduces high quality resonant modes withinthe band gap of the erstwhile periodic structure. We work out some of the possible configurationswhich support localization of light and further discuss the effect of the degree of randomness onoptical localization.

Non-diffracting Bessel beam of zero order derived from picosecond pulses was utilized to ablationsilver in double distilled water creating nanoparticle solutions (colloids) and nanostructured targets.The ablation was carried out by placing the target in a pyrex cell containing the solvent and trans-lating the whole cell by placing it on a X-Y stage. Several line structures were written with differentinput energies. Depending on the input energy either single or double ablation was possible. The sep-aration between the lines was 60 mircons. The prepared Ag colloids (four different energies of 200,600, 800, 1000 microjoules were used) were characterized by UV-visible absorption spectroscopy.It was observed that the peak position of localized surface plasmon resonance was nearly constant

and located near 407 nm. However, the absorbance of the colloids increased with increasing inputenergy. The colloids were also characterized for their third order nonlinear optical susceptibilitiesand the nanostructured targets were utilzied for explosive molecules (e.g. CL_20) detection with sur-face enhance Raman scattering technique. Complete details of fabrication and characterization ofnanoparticles and nanostructures will be presented in this paper.

Nowadays the field of nanotechnology is at the forefront for what concerns both theoretical knowl-edge and technological development. A key tool for a better understanding of the (pohoto)physicsof matter is spectroscopy. In particular, time-resolved photoluminescence (PL) spectroscopy allowsus to follow in time non-equilibrium state populations. This information, together with other insightscoming from different experimental techniques, provides helpful support for the study of both oldand new materials. With the aim of building a tool as flexible as possible for different photophysi-cal problems, we developed a state-of-the art photoluminescence spectroscopy system based on aTi:Al2O3laser source (80MHz, pulse duration: 150fs). A broad spectral coverage is granted by the tun-ability of the laser (680-1080nm) and its second harmonic (340-540nm); further wavelength regionscan be reached thanks to a home-build Optical Parametric Oscillator (1000-1400nm) which doubledcan cover from 500 to 700nm. High temporal resolution, around 2ps, is provided by a streak camera(spectral range: 300-850nm). For infrared wavelengths, a PMT with Time-Correlated Single-PhotonCounting electronics (300-1400nm, temporal resolution: 100ps) is employed. For long-lived species,an acousto-optic modulator allows the excitation at a rate variable between 80MHz and tens of kHz.Furthermore, for those samples which display microdishomogeneities (eg. crystalline structures) orwhich are microscopic (eg. biological cells, monolayers of inorganic materials), a home-made con-focal microscope is able to perform PL maps and depth scans. Few examples of applications will bepresented.

In the present study, the electrical properties of the fabricated Au/poyvinyl Pyrrolidine (PVP)/n-InP Schottky diode are anneaed at different temperature by means of J-V and C-V techniques. I isaso observed that Au/PVC/n-InP structure shows an excelent rectifying behavior. The extracted bar-rier height and ideaity factor of as-deposited Au/PVC/n-InP schottky contact is 0.72 eV, 0.80 eV (C-V)and1.47. However, the barrier height (BHs) of the Au/PVP/n-InP Schottky contact increases to 0.83 eV(J-V) and 0.88 eV (C-V) when the contact is anneaed at 100 degree centigrade for 1 min in nitrogenatmosphere. Upon anneaing at 200 degree centigrade, the BH value deceases to 0.70 eV (J-V), 0.78eV (C-V) and the ideaity factor increase to 1.48 repectively. It is seen that the PVP ayer increase the ef-fective barrier height of the stucture since this ayer creates the physica barrier between the Au meta

Atomic Force Microscopy (AFM) is well known as a multi-purpose tool for investigating a wide rangeof different samples with nanometer scale resolution under controlled environmental conditions. Wedeveloped a new imaging mode: SQuantitative ImagingT (QIZ), which is based on fast force curvesand combines the needs of user-friendliness with the opportunity of obtaining nanomechanical prop-erties simultaneously with topography. QITM has allowed overcoming the challenges of traditionalimaging, which were difficult for samples with steep edges, sticky or loosely attached to the surface.The novel QIZ tip movement algorithm prevents lateral forces and controls the vertical forces fornondestructive imaging at each pixel. QIZ has been designed to offer quick and intuitive imagingcapabilities of challenging samples even for AFM beginners. Force distance curve can be analyzedto extract contact point images, Youngt’s moduli images, or even recognition events. This imagingtechnique in combination with functionalized cantilevers allows for chemical and electrical measure-ment of the samples. Integrating the AFM module on the inverted microscope and combining AFMand optical microscopy techniques such as Fluorescence microscopy Laser Scanning Confocal mi-croscopy, Tip enhanced Raman microscopy and Super-resolution microscopy, allows for overcomingthe AbbeŠs resolution limit imposed by optical limitation and combining them with AFM which allowsfor nanometer resolution. Thus combination of atomic and optical microscope images not only gen-erates high resolution images, but can be used to resolve and correlate structural information withoptical properties.

ZnO nanoparticles doped with transition metal ions like Ag, Mn, Cu and Ni were synthesized by sim-ple solvo-thermal method. Synthesized nanoparticles were characterized through UV-Vis absorption,emission, FTIR and TEM. Systematic investigation of nonlinear absorption and scattering properties ofthe nanoparticles was carried out using Z-scan technique under nanosecond and picoseconds pulseexcitation. Synthesized nanoparticles exhibited absorption in the UV region in the UV-Vis extinctionspectra and emission in the visible region in the emission spectra. TEM analysis revealed that the ob-tained particles were spherical in shape with an average size of 10 nm. Z-scan measurements werefit theoretically to estimate both two-photon absorption (TPA) and nonlinear scattering coefficients(NLS). ZnO nanoparticles doped with Ag and Mn exhibited higher TPA, NLS and lower optical limitingthreshold values compared to Ni and Cu doped ZnO nanoparticles. These results suggest that thenanoparticles can be used as a potential optical limiting material.

This paper presents a novel class of MWCNT’s and ZnO doped PVA nanocomposites prepared byusing coagulation and solvent casting method. For doping purpose, the ZnO nanoparticles were pre-pared by using precipitation method. Along with that MWCNT’s (Multi wall carbon nanotubes) usedfor doping purpose was treated with sulfuric acid and nitric acid taken in 3:1 volume ratio solution tocreate carboxylated MWCNT’s. Further prepared ZnO and treated MWCNT’s are doped into PVAmatrixby coagulation technique and PVA nanocomposites is prepared by simple solvent casting technique.The Fourier transform infrared spectroscopy (FTIR) of nanocomposite film detects the irregular shiftin the bands of doped PVA nanocomposites indicating the presence of intra/inter molecular hydro-gen bonding creating the interactions between the nanoparticles and neighboring OH group of PVA.Crystallinity of the prepared nanocomposites films were investigated using X-ray diffraction (XRD)explores the synthesized nanoparticles have average particle size of 70 nm and explains the complexformation and variation in crystallinity of the nanocomposites due to interaction of dopants. The de-crease in optical energy band gap of nanocomposite films and the information of Urbach Energy (Eu)regarding the crystallinity was assessed by UV/Vis spectroscopy. By universal testing machine (UTM)the mechanical properties of doped polymer films found escalation for doping percentage concentra-tion x= 7.5wt%. The phase homogeneity, film morphology, chemical configuration of the nanocom-posites is inspected using Atomic force microscope (AFM), scanning electron microscope (SEM) andEnergy dispersive analysis of X-rays (EDAX).

Several nanostructures are being explored for passive optical limiting application for protection ofhuman eye and imaging device from hazardous levels of exposure of intense laser radiations. Amongthese, carbon nanostructures have been reported to have broadband optical limiting response. In this,context we report here the enhanced optical limiting response of Detonation Nanodiamonds(DNDs)decorated with metal nanoparticles. Unconvetionally, we have adopted pulsed laser ablation (in liq-uid) technique to decorate DNDs with Gold, Platinum and Palladium nanostructures. Electron micro-scope and EDAX confirmed the presence of metal nanostrutures over DNDs. Optical limiting responsewas evaluated using a modified open aperture z-scan technique which permitted us to evaluate in-dependent contibution from nonlinear scattering and nonlinear absorption processes. Unlike, PrisitneDNDs which exhibited nonlinear scattering, metal deorated DNDs exhibited stronnger nonlinear ab-sorption at both visible (532 nm) and at NIR (1064 nm) making them potential for broadband opticallimiting applications. On metal decoration, optical limiting threshold of DNDs were reduced from 56Jcm−2to 3.5 Jcm−2.

Utilizing ultrafast laser ablation in liquids (ULAL), a simple yet proficient technique, we successfullyfabricated plasmonic nanostructured substrates. This technique facilitates fabrication of impurityfree metal nanoparticles (NPs) and well textured nanostructures (NSs) in a single experiment. Wehave performed the ULAL of copper, silver, aluminum, and silicon in a variety of liquids using bothpicosecond and femtosecond pulses. The resulting NSs have been effectively utilized for explosivesdetection (including RDX, HMX, TNT, Cl-20, ANTA, and Nitropyrazole) using the technique of surfaceenhanced Raman spectroscopy (SERS). Enhancement factors were evaluated in each case and weobserved that with silver NSs we could detect pico-molar/femto-molar concentrations of an explosivemolecule of Nitropyrazole. We will summarize all the results obtained from our measurements.

Sol-gel process is based on the hydrolysis and condensation of metal alkoxides, and has in the pastyears, gained great importance in the fields of glass and ceramics. This wet chemistry process, provesto be advantageous over other widely used physical vapour deposition techniques. High optical qual-ity films of numerous compositions can be deposited by this low-cost technique. Sol-gel fabricatedplanar waveguides and multilayered films forming 1-D photonic crystals are very promising. Here,we present our recent results on fabrication and characterization of two vital components of inte-grated optics, namely, europium doped SiO2-SnO2 1-D photonic crystals and SiO2-ZnO waveguides.These systems for integrated optics were fabricated by sol-gel route and dip-coating processing andthey were assessed for their optical and spectroscopic properties. The 1-D photonic crystals wereobtained by depositing alternating layers of SiO2 and SnO2 as a materials system with index contrastsufficiently large for obtaining a wide tunable stop-band. High optical quality films with reflectance>96% in the stop-band were achieved. Spectral management of Eu3+ emission in the fabricated 1-Dphotonic crystals has been demonstrated. We would also present ZnO nanoparticles embedded SiO2waveguides, which are a new candidate for fabrication of low-loss glass-ceramic active-waveguides.Propagation loss of 1.4s0.2 dB/cm at 632.8 nm was observed in these transparent waveguides. Theas-prepared waveguides contained nanoparticles of average size 15 nm uniformly dispersed in theSiO2 matrix. The tuning of the optical and spectroscopic properties by controlled heat-treatment ofthe as-prepared active-waveguides has been demonstrated.

We would present and demonstrate a new type of single resonator based planar metamaterialdesign exhibiting electromagnetically induced transparency(EIT)-like transmission behaviour. Thisnovel design involves a physically coupled split-ring resonator(SRR) and a dipolar ring as opposed tomany inductively coupled resonators explored in the past. Both experiments and simulations reveal adispersive transparency due to the coupled resonances and the underlying mechanism. Furthermore,the conductive and inductive coupling scenarios for this structure are compared in which conductivecoupling is found to coerce the direction of light induced currents and stronger in effect than inductivecoupling. Resonance and group-index tuning is achieved by moving the bar coupling SRR and the ring.Hence, we show the conductive coupling has potential in tailoring coupled resonances of desiredquality factor and fabricating metamaterials with designer dispersion.

Organic bulk heterojunction solar cells are a promising candidate for low-cost next-generationphotovoltaic systems. In bulk-heterojunction polymer solar cells, conjugated polymers and fullerenederivatives [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) function as the electron-donating andelectron-accepting materials, respectively. In this paper, we report the photovoltaic response of thesolution processed bulk heterojunction (BHJ) solar cell based on MEH-PPV: modified PECM blend. TheBHJ showed power conversion efficiency (PCE) up to 1.78%. The PCE has been further improved upto 1.93% after thermal annealing of the active layer. The increase in the PCE with the thermallyannealed blend is mainly attributed to the improvement in incident photon to current conversionefficiency (IPCE) and short circuit photocurrent (Jsc). Thermal annealing leads to an increase in boththe crystallinity of the blend and hole mobility, which improves the PCE. Key Words: Organic bulkheterojunction solar cells, Modified PCBM, MEH-PPV, Active Layer and Annealing.

Rare earth activated 1-D photonic crystals were fabricated by rf-sputtering technique. The cavityis constituted by an Er3+-doped SiO2 active layer inserted between two Bragg reflectors consistingof ten pairs of SiO2/TiO2 layers. SEM microscopy is employed to put in evidence the quality of thesample, the homogeneities of the layers thickness and the good adhesion. NIR transmittance andvariable angle reflectance spectra confirm that the presence of a stop-band from 1500 nm to 2000nm with a cavity resonance centered at 1749 nm at 0° with a quality factor Q is about 890. Theinfluence of the cavity on the 4I13/2→4I15/2 emission band of Er3+ ion is also demonstrated.

Wavelength filtering and selective light harvesting is a requirement in applica-tions dealing with biological sensing and analysis. The device is designed to reflect the undesirablewavelengths and focus the wavelenth of interest. It consists of a microfluidic channel in a fused silicasubstrate containing a fluorescent dye solution. The surface of this substrate is spin coated with a 1Dpolymeric photonic crystal(1DPC) with a band gap centered at the excitation wavelenth of the dye. Mi-cro Binary Fresnel lenses customized for focusing the fluorescence wavelength are fabricated on the1DPC. So in essence we demonstrate a wavelength filtering and selective light harvesting optofluidicdevice. The fabrication of such a device involving integrated optics like Fresnel lenses and 1DPC anda microfluidic channel is achieved using by femtosecond laser micromachining technique(FLM). Tra-ditional lithographic techniques are very cumbersome and involve many steps for fabrication. FLM isa very versatile technique for fast prototyping. It is inherently 3D without masking steps and a 1 stepprocess for both in volume and on the surface microfabrication for transparent materials. MoreoverFLM relies on non linear absorption of energy thus allowing precise micromachining avoiding thermaldamage. Ultrashort pulses resulting in non linear processes restricts the material modification only tothe focal volume, thus FLM can be used for any material.

Monitoring the growth of nanoscale materials using state of the art characterization tools is paramountfor understanding reaction and growth mechanisms. Advanced techniques involving in situ probingof chemical reactions such as in situ transmission X-ray microscopy, fast single-particle spectroscopy,small-angle X-ray scattering, etc. are currently being developed. However, these tools are complex,not easily accessible, and do not necessarily provide the temporal resolution required to follow theformation of nanomaterials in real-time. Herein, we focus on utilization of a simple millifluidic chipfor an in situ real-time analysis of morphology and dimension-controlled growth of gold nano- andmicrostructures with a time resolution of 5 ms. The gold structures formed were characterized usingsynchrotron radiation-based in situ X-ray absorption spectroscopy, 3-D X-ray tomography, and high-resolution electron miscroscopy. These gold structures were found to be catalytically active for theconversion of 4-nitrophenol into 4-aminophenol and ferricyanide to ferrocyanide, providing an exam-ple of the potential opportunities for time-resolved analysis of catalytic reactions. The technique canalso be applied to analyze time-resolved growth of other types of nanostructured materials and haspotential to revolutionalize a broad range of fields with its capability to probe at least a 10-fold higherconcentration in comparision to traditional microfluidics.

Lasers are being extensively used in material processing, this is due to their ability to deliver en-ergy in a controlled fashion and in a localized volume/ area. In particular the Selective Laser sinteringhas gained popularity for applications in 3D printing of objects in micro and macro scale.

125 Optical and structural properties of Germanium nanoparticles synthesizedby nanosecond laser ablation in liquids


Poster P-541 [ Dec 20, 19:25-20:55 ]

Germanium (Ge) nanoparticles (NPs) are synthesized in a one step process by using pulsed laserablation, with nanosecond laser pulses, of bulk Germanium in different liquids such as water, ace-tone, toluene and chloroform. Characterization of synthesized Ge NPs with different techniques suchas UV-visible absorption spectroscopy, photoluminescence, micro-Raman spectroscopy, transmissionelectron microscopy (TEM) reveals the formation of NPs in liquids. The mean size of the Ge NPs isfound to be less than the Bohr-exciton diameter of the Ge which results into the quantum confinementeffects in the NPs. We have explored the effect of solvent on the structural and optical properties ofthe Ge NPs in the colloidal solution. In acetone and water the Ge NPs are formed without agglom-eration and exhibit blue green luminescence whereas in toluene and chloroform the NPs are eitherformed along with a graphitic carbon network or they are embedded inside graphite layer. These NPsare observed to be agglomerated and exhibit green luminescence. HRTEM measurements reveal thatthe NPs formed in water and acetone are highly crystalline whereas in toluene and chloroform theyare partially crystalline and amorphous in nature.

127 TiO2doped with Bi - Visible Photocatalytic nanomaterials for Textile effluenttreatment


Poster SP-751 [ Dec 21, 19:20-20:50 ]

Heterogenous semiconductor photocatalytic process is one of the advanced oxidation technolo-gies to treat pollutants of chemical, textile, and pharma industries. It has received extensive attentionfor over two decades for purifying contaminated water and air. Among different semiconducting ox-ides titanium oxide is generally recognised as the most promising photocatalyst due its biological andchemical intertness, strong oxidising power, cost effectiveness, long term stability and environmetalfriendly. Recently, fabrication of titania hollow microspheres has also attracted enormous attentionbecause of their low density, large surface area, good surface permeability as well as high light -harvesting efficiencies. However the performance of the titanium oxide takes place in UV irradiation,and to make it work in visible range we have added Bismuth as dopant. In the present investigation,we have adopted sol-gel process to synthesise TiO2 doped bismuth nanopowders. The as prepareddried samples have been sintered at different temperatures ranging from 200 oC to 800 oC for 1 h in airambient. The sintered samples have been charcaterized for their structural, chemical and morpholog-ical properties by employing X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR)and Scanning Electron Microscopy (SEM) techniques, respectively. The samples have been tested fordegradation of the standard dyes methylene blue, methyl orange and methhylred, where we haveobserved 600 oC sintered sample has degraded above mentioned dyes within 30 min. The optimisedcomposition has been tested aganist textile effluent which has shown excellent degradation with in30 min. Experimets are under progress to treat different textiles effluents.

Magnetorheological(MR) fluids are a class of smart materials whose rheological properties rapidlyvary with the application of magnetic field. MR fluids are the suspensions of soft magnetic particlesin a carrier fluid. The suspended magnetic particles form a chain like structure that resists the fluidflow. This change in the material appears as a rapid increase in the apparent viscosity. Many smartsystems and structures would benefit from the change in the viscosity or other material properteisof the MR fluids. The applications of these MR fluids includes brakes, dampers, clutches and shockabsorber systems. In this line, recently cobalt ferrite nanoparticles have been synthesized by a simplewet chemical method. These ferrite nanoparticles were fired at temperatures 600 C and 800 C forsix hours. The composition, phase and morphology were determined by energy dispersive X-ray

The MR fluids were made with cobalt ferrite and PVA(Poly VinylPyrrolidone), caster oil. It was found that the particle size increases with the firing temperature whichinturn affects the MR properties of the fluids. The MR properties of the fluids were measured within-house equipment and results on such studies were presented in this paper.

132 *Characterization of Nano structures in Functional materialsG. V. S. Murthy††Materials Science and Technology Division, CSIR-National Metallurgical Laboratory, Jamshedpur 831007,India


It very well known that nano structures even if quite dispersed in a host matrix play an importantrole in the intended performance of the materials. These exhibit properties which are different fromthe accepted behavior. One such example is the break Udown of Hall-Petch relationship which predictsa relationship between the grain size and the strength of the material. So a rigorous characterizationof these structures is very essential. In the present paper techniques like Mossbauer spectroscopy andUltrasonic are used to characterize the sub-microscopic structures. Through Mossbauer spectroscopyit has been possible to identify the super paramagnetic iron oxide due to the inherent resolution of 1in 1013as well as quantify accurately. Similarly Ultrasonic was able to precisely follow the precipitationprocess in nickel-base alloy. It has been observed that Ultrasonic is far more sensitive than the anyother techniques in following the precipitation process and its degradation. It can be concluded thata rigorous characterization of the sub-microscopic structures is possible.

One of the challenges of active transport at low Reynolds numbers is to enable small objects toperform autonomous, directional motion (so-called self-propulsion). A promising approach consists inemploying catalytic, chemically powered micromotors that can extract SchemicalT free energy fromthe surrounding liquid environment and to transform it into mechanical energy. These motors havebeen used in recent times for applications such as transport of inert cargo and environmental re-mediation. While there is a relatively good understanding of the motion of single active particle,theinfluence of the composition of planar walls on the motion of active particles has not been experimen-tally addressed. Here, we use catalytically active spherical Janus micro-motors in order to investigateexperimentally their motion on different substrates. We further try to understand the interaction thatexist between the surface and the self-propelled particle and explore ways to modify this interac-tion. One of the difficulties in developing selfpropelled micromotors is directional control. At theselength scales Brownian forces constantly randomize the direction of the motors. Here we make useof our understanding of the surface-particle interactions to develop a novel guiding system for Janusparticles.

136 *Magnetism at nanoscale: Nano-small meets Ultra-fastJyoti Ranjan Mohanty††IIT Bombay, India


Modern magnetic devices (GMR read heads, magnetic sensors, hard disks and spintronics devices)relies on storing or manipulating magnetic information in smaller length scales (nmŠs) at faster timescales (nano-seconds to femto- seconds). Materials with perpendicular magnetic anisotropy (PMA)are attracting significant scientific interest, motivated in particular by the technological relevance ofthis class of materials for applications in high bit-density hard disk storage devices, current-drivendomain wall shift registers with low critical current densities and programmable magnetic logic ele-ments. All these applications rely on the magnetic switching or controlled motion of magnetic domainwalls at the nanometer length scale and sub-picosecond time scale. Advancement of nano-science al-lows us to prepare structure in nanometer size both by self-assembly and lithography. X-ray magneticcharacterization provide us information on nanoscale with element specificity, chemical sensitivity,sensitivity to charge, orbital and spin ordering, high spatial resolution, and faster time scales. Inthis talk, I will present an overview of nanoscale magnetism in thin films and ultrafast magnetizationdynamics of magnetic multilayers exhibiting labyrinth-like domains due to perpendicular magneticanisotropy (PMA). The application of an ultra-short laser pulse on a ferromagnetic film allows chang-ing its magnetization in the femto-second time scale . This scientifically fascinating effect has alsotechnological implications, e.g., regarding the ultimate speed at which information can be stored andprocessed in magnetic storage media. Even today, the microscopic understanding of laser inducedultra-fast demagnetization remains a challenging issue. The recent development of ultra-short softX-ray pulses by X-ray free electron lasers opens new perspectives in this field. I will give an overviewon this topic with our recent findings. On theoretical point of view I will present micromagnetic simu-lations to understand the energetic and dynamics of the nanoscale magnetic systems.

Persistent photoconductivity (PPC) is quite different from the conventional photoconductivity ofsemiconductores and can lead to unique application in sensors, actuatores, and non volatile memo-ries. The ZnO nanowires have large surface sensitivity which makes them suitable for gas sensorsand UV detectors.The conductivity of these ZnO nanowires increases rapidly when these nanowiresare illuminated with UV light (energy greate than band gap). The highly increased photoconductivitypersists for long time even after the UV light is turned off. There are lots of reports on this persistentphotoconductivity process but the basic mechanism behind the persistant photoconductivity processand defcets responsible for it is still unclear. In the present report, we are reported the role of oxy-gen vacancies behind the persistent photoconductivity of ZnO nanowires. The ZnO nanowires weresynthesized using chemical vapor deposition method. The defects responsible for persistent pho-toconductivity are investigated using electron paramagnetic resonance (EPR) spectroscopy, Fouriertransform infrared spectroscopy (FTIT), photoluminescence and Raman measurements. Our resultsclearly show that oxygen released from the nanowires surface with UV light illumination and the oxy-gen vacancies related defects increases which are mainly responsible for photoconductivity of theseZnO nanowires. These ZnO nanowires were also embadded in polydimethylsiloxane (PDMS) poly-mer and the strain dependent persistent photoconductivity is also studied on the embadded ZnOnanowires.

We have synthesizedMgSiO2 that has exhibited high ZT values which renders it a viable option for various thermoelectricdevices and applications. A lot of focus has been given towards the enhancement of fluorescencesignals that facilitate the generation of superior signal to noise ratios in fluorescence based assays inbiological/medical sciences. Fluorescence is an isotropic phenomenon wherein the signal collectionefficiency of the associated protocol is usually <1%. On coating fluorophores on thin metal films,the energy of fluorescence was found to couple to the surface plasmon modes of the metal leadingto highly directional and wavelength resolved emission known as Surface Plasmon Coupled Emission(SPCE). On coating MgSiO2 on the conventional silver (Ag) substrate; the energy of fluorescence fromRhodamine 6G was found to efficiently couple with the plasmon modes of Ag leading to a coupledemission signal of high signal to noise ratios. We report an enhancement of about 27 fold in theemission signal intensity of the fluorophore coated Ag-MgSiO2substrate in comparison to the normalfluorescence yield of the fluorophore. Thus MgSiO2 can be potentially used for thermoelectric andsensor based applications.

The nano sized titanium oxide (TiO2) nanoparticles (NPs) were synthesized via wet chemical method.As synthesized TiO2 NPs were characterized by X-ray powder diffractometry (XRD) to confirm the crys-talline nature. The surface morphology and particle size of nanoparticles were analysed by high res-olution scanning electron microscopic method (HRSEM). UV-visible diffusion spectroscopy employedto determine its band gap. The different concentration nanofluid samples of TiO2 NPs dispersed inethylene glycol were prepared and mixed thoroughly using ultrasonication process. Ultrasonic veloc-ity and density values were measured for these different concentrations of titanium oxide nanofluids.The acoustical parameter such as adiabatic compressibility, intermolecular free length, and acousticimpedance are calculated from the experimental data. It is obsereved that ultrasonic veloctiy showslinearity with particles concentration and the results are discussed.

Poly(butylene terephthalate)/Multiwalled carbon nanotube composites were prepared bymelt mix-ing. The nonisothermal crystallization and thermal behavior of Poly(butylene terephthalate)/Multiwalledcarbon nanotubes composites were respectively investigated by differential scanning calorimeter.The kinetics was then analyzed using Avrami, Kissinger and Takhora model. The introduction ofMWCNT into neat PBT increases the viscosity of the composite system, hindering rearrangementof the PBT chain segments and increasing the activation energy value as a result. In other words,like those observed on the other polymer/CNTs composites,MWCNT in the PCTs not only acts as anucleating agent to facilitate crystallization but also as a physical hindrance to retard crystallization.

In this work we prepared the hierarchically ordered micro-mesoporous carbon with enlarged anduniform micropores, specifically tailored for the high level adsorption of environmental pollutantbisphenol A (BPA). The size of both primary micropores 1.3 nm and the primary mesopores 9.0 nmcould be tuned by controlling the condensation behaviour of Phloroglucinol and Terephthaldehyderesin in a tri-constituent system based on evaporation induced self-assembly. As a result of this spe-cial structure was able to develop high surface area in range 623-1985 m2 g−1 and large pore volume0.7-2.3 cm3 g−1. By tuning the micropore size to accommodate the molecular dimension of BPA. anultra high adsorption capacity 1106 mg g−1was achieved. The Kinetic studies revealed that high poreinterconnectivity and micropore accessibility were the key to unrestricted adsorbate diffusion throughthe pore channels and subsequent high level adsorption.

In this paper, we discuss the science and technology of smart nanomaterials with emphasis on en-ergy and sensing applications. Recently, we have observed a remarkable sub-bandgap photovoltagephenomenon with semiconductor BiFeO3 nanowires. This significant photoresponse is attributed tothe dominant nature of surface states. The surface field originated from excess surface charges playan important role in the charge separation and carrier lifetimes in these nanowires. Although surfacestates do not influence the optical properties of bulk materials and thin films, they are dominant innanostructures because of their large surfac-to-volume ratios. Such a sub-bandgap photoresponse ofsemiconductor nanowires can be basis for novel photovoltaic and photodetector devices. An array ofthese nanowires should provide a key to develop next generation solar cells capable of cost-effectiveenergy conversion on a large scale.On the other hand, a highly sensitive and selective chemical sen-sors are always in a great demand in biomedical, chemical and environmental monitoring. The sur-face of nanostructured materials are often highly-defective due to the existence of dangling bondsor surface reconstruction. The adsorption of small amounts of chemical species typically less thana monolayer of molecules, or the occurrence of surface reactions such as oxidation/reduction reac-tions can change the electrical and optical properties of nanomaterials significantly. Therefore, highsurface-to-volume ratios of nanomaterials bring many aids to sensitivity, selectivity and stability ofsensor technology.

Polymers polymethylemethacrylate (PMMA) and Polycarbonate (PC) are wonderful low cost ma-terials which can be easily tailored and shaped. However they have poor mechanical, thermal andelectrical properties which are required to be enhanced in several applications where alongwith highstrength, a quick heat transfer becomes a necessity.

fabricating composites of varying concentrations of CNTs with PMMA and PC and measurements ofthermal conductivity data by a simple transient heat flow. The samples in disk shapes of around 2cm diameter and 0.2 cm thickness with CNT concenetrations varying upto 10% were fabricated. Bykeeping one end of the discs at steam temperature, the temperature of the other end was noted foreach sample after 10 s. The rise in temperature was correlated with thermal conductivity which wasappropriately caliberated. We found that both PMMA and PC measured high thermal conductivity withincrease in the concentration of CNTs. The thermal conductivity of PMMA rose from about 0.2 W/mKto 0.4 W/mK at 10% of CNT whereas for PC, it rose from about 0.2 W/mK to 0.9 W/mK at 10% of CNT.It is thus observed that modification in thermal properties is easily achieved by making CNT basedcomposites using only upto 10% of CNTs in PMMA and PC and enabling quicker heat dissipation inthese materials.

149 Single Walled Carbon Nano Tubes as Promising Highly Efficient RadiationShielding Material


Poster SP-756 [ Dec 21, 19:20-20:50 ]

It has been shown that Carbon Nano Tubes (CNTs) could convert microwave energy into lightand/or heat in high yields. These studies demonstrate that nano-materials could exhibit outstand-ing electromagnetic effects.In this account, we report that single walled carbon nanotubes (SWC-NTs) could very efficiently absorb gamma-rays of different energies when compared to MWCNTs, andGraphene and even comparable to lead. In the present study, the gamma-ray attenuation usingSWCNTs, MWNTs, and Graphene were measured and compared with those of Graphite and Lead. Thelinear and mass attenuation coefficients for 13.95, 17.74, 5 1332.0, 59.54, 80.9, 276.4, 511.0, 661.6,1173.0 and 1332.0 keV gamma-radiation were measured using radioactive sources 133Ba, 137Cs, 22Na,60Co and 241Am obtained from BRIT, BARC, Mumbai, India. A good geometry set-up and an optimizedand calibrated HPGe detector based 8K Nuclear MCA gamma ray spectrometer has been employedfor the direct and absorbed spectra. It is noteworthy that the nano carbons possessing cylindricaltube-like structures exhibit higher X-ray and -ray attenuation coefficients than that of bulk carbon.The mechanism for these observations is far from clear and it cannot be understood by conventionalparticle theory. The unusually high shielding effect of SWCNTs is likely to originate from their uniquecylindrical nano-morphology.

In the experiments, zinc acetate (Zn(CH3COO)2.2H2O is used as startingmaterial, methanolas organic solvent and mono ethanol ammine as surfactant. Aluminium sulphate is used for doping Al.All the sols were mixed in appropriate proportions so that there is 2 percent Al doping in ZnO. Preparednanopowder was given pellet shape by applying pressure of 300 MPa. Pellets were annealed in airat different temperatures from 300 degree celsius to 600 degree celsius for 3 hours. Pellet samplesmade were labelled AZ-2 (2 percent Al doped in ZnO). The activation energy values for sample AZ-2from the Arrhenius plot is found to be 0.043 eV for temperature range 60 degree celsius to 140 degreecelsius and 0.019 eV for temperature range 180 degree celsius to 200 degree celsius. Lower values ofactivation energies were observed in the two regions indicating that this sensing element has lower

153 Studies on correlation between the wettability and transparency of Al-dopedzinc oxide thin films for smart window application


Poster SP-757 [ Dec 21, 19:20-20:50 ]

Transparent conducting oxides (TCOs) have been increasingly studied across various technicalfields such as flat-panel displays, thin film solar cells, energy conserving architectural windows, lowemissivity coatings, heat-reflecting coatings and antistatic window coatings. It has been well knownthat indium tin oxide (ITO) is the most widely used TCOs, because of its high conductivity and trans-parency. Owing to the toxic nature, chemical instability and high cost, there is a need to replace analternative material for ITO as TCOs. Among many TCOs, one of the viable candidates is Al-dopedZnO (AZO) which has sufficiently high conductivity and transmittance of over 90% in the visible re-gion. When the TCO (top layer of solar cell or OLEDs) comes in contact with water molecules, boththe surface chemistry and morphology affects the adhesion and alignment of molecules on the sur-face, which in turn affects the conductivity of the TCO films. Thus the interaction of coating surfaceswith water molecules must be studied to understand the stability of coatings for outdoor applica-tions. Further, adsorption of water on metal oxide surfaces is an important subject in its own right,a microscopic understanding of wettability of TCO surfaces is fundamentally interesting phenomenonand practically valuable. In the present work, transparent AZO films are deposited on microscpicglass slides by solution based approach. The systemic investigations of the effect of effect of dopantconcentration on the wettability and optical properties of TCO films are investigated.

155 *Field induced Transformation of Carbon Nanotubes to Graphene QuantumDots and Graphene Nanoribbons

Vijayamohanan K. Pillai†† [email protected], Central Electrochemical Research Institute (CECRI), Karaikudi. India.


Graphene has attracted much attention recently due to the possibility of tailoring their dimen-sionality and structure to facilitate a change in their fundamental properties including conductivityand electron transfer characteristics in comparison with similar behavior of their 1D, 2D and 3D ana-logues). Doped GQDs (N-GQDs) are also interesting because nitrogen atoms could be used exten-sively to modify edge states and also to functionalize to tune solubility, hydrophilicity, biocompat-ibility etc. facilitating specific applications. For instance, N-GQDs have been studied theoreticallyand these calculations suggest that nitrogen atoms located at their edge and near the edge promotethe electrocatalytic activity towards the oxygen reduction reaction, even to replace noble metals likeplatinum for fuel cell applications. In this lecture I will describe mechanistic aspects of the transfor-mation of carbon nanotubes to graphen nano ribbons(GNRs) and GQDs using spectro-electrochemicaldata collected by in situ experiments to unravel some of their unique size dependent features. Spec-troscopic techniques such as X-ray photoelectron spectroscopy(XPS), UV-visible spectroscopy, andPhotoluminescence measurements would be used in conjunction with electrochemical techniques todemonstrate their unique electronic structure for average GQDs from high resolution transmissionelectron microscopy and Atomic force microscopy as 3 s 0.3 nm. Multifunctional properties suchas electrocatalytic properties, Photoluminescence, Electroluminescence and unique single electrontransfer behavior of these individual graphene quantum dots and graphene nanoribbons would bediscussed with a view to facilitate their application potential in the fabrication of futuristic nano-electronic devices.

For educators, by educators.www.ConferenceDevelopmentCenter.comcdc@ConferenceDevelopmentCenter.com

Education must teach a person what life is, and

what its goals are. It must purify the heart and clar-

ify the vision. It must prevent pollution of the hand,

heart and head by habits injurious to the individ-

ual, society and the nation. It must promote virtues

and raise the moral and spiritual standards of the

educated.
