    ON THE PHOTOCHEMICAL OXIDATION OF BENZENE AND ITS RELEVANCE AT ENVIRONMENTAL LEVEL

    Laura Stella1, Roberta Seraglia1, Alberto Sturaro2, Rocco Rella2 and

    Pietro Traldi 1*

    1 CNR-ISTM, Corso Stati Uniti 4, Padova , Italy 2 CNR-IDPA, Corso Stati Uniti 4, Padova , Italy

    Benzene is one of the most monitored pollutants, due to its high level in high

    traffic and industrial areas. Previous investigations, performed by atmospheric pressure photoionization1,2,

    have shown that under light irradiation benzene reacts with oxygen, leading to phenol production. The same reaction has been observed by sunlight irradiation of benzene samples, as proved by GC/MS analyses. The phenol/benzene chromatographic peak ratio passes from 1.8×10-4 to 0.105 after 6 hours of sunlight irradiation, giving evidence that phenol can be produced at environmental level. To prove the validity of this hypothesis weekly air sampling was performed over a year (2006) and phenol/benzene ratio was found to be related to the sun radiation. It ranges from 0.046 to 1.114 and higher values are obtained for the late summer – early autumn period, when the sunlight exposure is higher. Considering that the LC50 values for inhalation of benzene and phenol are 9980 and 42 ppm respectively, it follows that the monitoring of phenol in air is an important point to be followed to ensure a valid air quality.

    Fragmentation reactions occurring in a mass spectrometer has been the basis of its applications in analytical and structural chemistry. Modeling these reactions have been attempted for over 50 years, with varying success. The main issues are ion structures, energetics, reaction kinetics, instrument effects, and neither of these are well known. Most experiments yield indirect information only, so theoretical methods are of prime importance to support, to understand and to complement experimental results. The two most relevant theoretical fields are quantum chemistry and reaction kinetics. After a short description of the application of quantum chemistry in mass spectrometry, the approach using reaction kinetic calculations will be explained. In this field energetics and excitation processes are of prime importance. Modeling does not only broaden our basic understanding of mass spectrometry, but can also be utilized in practice. This will be illustrated giving several examples: Discussions on the ‘effective temparature’ (which facilitates obtaining thermochemical information); designing new experiments (to increase fragmentation of peptides and proteins); understanding mechanism of ionization techniques (and to help designing better ones); selecting between alternative reaction mechanisms; understanding fragmentation of macromolecules; and predicting fragmentation of peptides.

    CH-8057 Zürich, Switzerland

    Nuclear Magnetic Resonance (NMR) is a spectroscopic technique which employs magnetic nuclei to study, among others, the dynamics of condensed matter at the atomic level. Thus, NMR has been and still is a successful instrument in the research field of solid electrolytes also known as solid ionics

    This paper passes revue of typical NMR experiments performed in solid ionics together with some examples from nanoionics.. The experiments to be discussed comprise: (i) measurements of the diffusion coefficient employing the pulsed-field gradient and the static fringe-field method; (ii) the experimentally related NMR imaging; (iii) double resonance experiments like spin-echo double resonance (SEDOR) and two-dimensional Fourier transform NMR (2D-FT NMR); (iv) various types of nuclear relaxation, in particular spin-lattice relaxation

    The NMR techniques yield information on topics like: type and number of mobile atoms and defects, diffusion pathways (e.g. dimensionality restrictions), atomic jump frequencies, activation energy and activation volume of these movements, diffusion coefficient with activation energy and prefactor, correlation effects in atomic movements, space correlation factor, cooperative phenomena, symmetry of atomic sites, behavior at phase transitions. These applications will be illustrated by giving examples from crystals, glasses, and polymers.

    Al.Armii.Krajowej, 13/15, 42-200 Czestochowa/ Poland The physical properties of functional hybrid nanocomposites were intensively investigated during the last decade. Among the reported functionalities, those in optics [1], electronics [2], photovoltaic [3] or optoelectronics [4] are very promising. As far as the functionalities are concerned, the active vectors consist in inorganic semiconducting nanocrystals. In this context, silicon carbide is a promising material due to its unique ability to adopt different crystalline polytypes which monitor the band gap and then the electronic and optical properties [5-7]. The SiC nanoparticles are characterized by versatile properties such dielectric behavior marked by interfacial polarizations [8-10] as well as the vibrational and luminescence properties which point out the main role of surface nature [6, 7]. Moreover, in hybrid materials based on inorganic nanocrystals, the interface effects between the organic and inorganic play a key role in the physical properties. So, an effective control of the surface states of the nanocrystals is an important challenge to tune the physical responses and their efficiency.

    This lecture deals with some relevant properties of silicon carbide nanocrystals as isolated objects or associated with polymer matrices to realize functional materials for optics, electronics and electrooptics. The investigations developed on bare SiC nanocrystas consist in analyzing the physical properties including vibrational [7, 5], structural [10], dielectric [8, 9], as well as both linear and nonlinear optical behavior [6]. For all these studies, predictive numerical methods were developed in parallel by using ab-initio, molecular dynamics and quantum chemistry calculations to interpret and point out the main relevant parameters which govern the physical properties [6,7]. However, no valuable applications of these materials can be undertaken without the structuration of nanocrystals inside appropriate host matrices. Thus, polymer matrices were used for the evaluation of the potentialities of hybrid systems based on SiC nanocrystals and polymer in the area of electrooptics through the large pockels effects demonstrated in these media as well as the creation of suitable large area of organic-inorganic interfaces for charge transport and recombination for electroluminescence applications. An overview of the different nano-SiC based composite architectures and relevant properties will be discussed.

    LOCAL MODES AND PHONONS AROUND PARAMAGNETIC

    DEFECTS IN SOLIDS

    Stanislaw K. Hoffmann

    Sciences, Smoluchowskiego 17, 60-179 Poznan, Poland

    Defects introduced into crystalline materials can modify their static and dynamical properties and can be used as probes for studying local crystal properties. Question is if a defect participates in phonon motions of a host lattice or it has its own dynamics. If so, what is a coupling between defect motions and collective motions of the crystal lattice? These questions are important in doped semiconductors, and in solids where defects are generated for modification of physical properties. Phonon spectra are available for rather simple inorganic solids where they can be theoretically calculated or measured by neutron scattering technique. The phonon spectra usually deviate significantly from Debye-type phonon spectra presented in most of textbooks of solid-state physics. Vibrations of a simple defect appear in a narrow frequency range are called local mode. Because of a low defect concentration the local modes can be not detected by neutron scattering, but can be detected by classical spectroscopy methods. Local modes can be identified by Raman and IR spectroscopy when appear in the optical phonon branch region. Local modes appearing in acoustic phonon region are difficult to observation. They can be detected in studies of electron spin relaxation measured by pulsed electron paramagnetic resonance methods [1,2]. An electron spin system of paramagnetic defects relaxes, after a pulse excitation (in time order of micro- to milliseconds), to initial equilibrium transferring the excitation energy to phonons and/or to local mode of the defect. These two ways can be distinguished in pulsed EPR measurements in a broad temperature range. In the lecture a method of local mode detection with electron-spin echo will be described and results will be presented for paramagnetic ions doped into inorganic and organic solids and for free radicals generated by ionizing radiation in crystals.

    CLASICAL AND QUANTUM ROTATION OBSERVED IN SMALL MOLECULAR GROUP BY NMR

    Poznan, Smoluchowskiego str. 17, Poland

    The motions of particles across potential energy surfaces is ubiquitos to condensed mater physics and is manifest in chemical reactions in the chemical and biological sciences. Often, the characteristic rate for motion between the wells may by adequately described by an Arrhenius law in which case the particles are making classical barrier hopping. However, when the mass of the particles is small and the activation energy is low then the dynamics reveal the underlying quantum mechanical nature of the particles and the motion at low temperature may be dominated by tunneling. These are observed for symmetrical rotors (CH3, NH3, CH4, NH4 and deuterated ones) where coherent tunneling with a well-defined characteristic frequency gives rise to discrete features in the motional spectrum. In my presentation the proton spin-lattice relaxation times in natural and partially deuterated ammonium hexachlorotellurate will be described. At high temperature (above 50K) the relaxation curve reveals the classical, hindered reorientation of the ammonium ion with the same activation energy for all studied samples Ea = 5.6 kJ/mol. Below 50K, the minima which appear in the T1 temperature dependencies are related to the “level-crossing”. The tunneling splitting of the ground torsional level in isotopic pure ammonium hexachlorotellurate is equal to 55MHz and increases with increasing deuteron concentration. The lowest temperature minimum in isotopic pure (NH4)2TeCl6 powder can be interpreted as a result of the rigid ammonium ion’s classically reorientted about the threefold crystallographic axis. The “limited jumps” of NH4

    + are characterized by the angle ∆ = 4o between the NH bond and crystallographic [111] direction.

    Artificial photonic antenna systems have been realised by incorporating organic dyes in a microporous material.[1] We have been using zeolite L in most of our experiments as it has proven to be a very versatile host material. Zeolite L crystals are cylindrically shaped, porous aluminosilicates featuring a hexagonal symmetry. The size and aspect ratio of the crystallites can be tuned over a wide range. A nanometre sized crystal consists of many thousand one dimensional channels oriented parallel to the cylinder axis. These can be filled with suitable organic guests. Geometrical constrains of the hosts framework lead to supra¬molecular organisation of the guests in the channels. Thus very high concentrations of monomeric dye molecules can be realized. A special twist is added to these systems by plugging the channel openings with a second type of fluorescent dye, which we call stopcock molecule. The two types of molecules are precisely tuned to each other; the stopcocks are able to accept excitation energy from the dyes inside the channel, but cannot pass it back.[2] The supramolecular organization of dyes inside the zeolite channels is what we call the first stage of organization. It allows light harvesting within the volume of a dye-loaded zeolite L crystal and also radiationless energy transport to either the cylinder ends or centre. The second stage of organization represents the coupling to an external acceptor or donor stopcock fluorophore at the ends of the zeolite L channels, which can then trap or inject electronic excitation energy. The third stage of organization is realised by interfacing the material to an external device via a stopcock intermediate. We recently observed that electronic excitation energy transfer in dye-zeolite L materials occurs along a well specified axis.[3] This important finding means that organized, uni-directional materials can be prepared. In order to achieve this, we prepared zeolite L monolayers, filled them with luminescent dyes, and finally added a stopcock. These procedures and their repercussions on the design of novel materials will be discussed.[4], [5] [1] G. Calzaferr i , S. Huber , H. Maas, C. Minkowski Photon-Harvesting Host-

    Isotope separation by chemical exchange is very popular for light elements, such as hydrogen, lithium, boron, carbon, nitrogen and oxygen. Due to the mass dependence of the isotope effects, the chemical exchange was considered not to be applicable to uranium enrichment. However uranium enrichment processes by ion exchange and solvent extraction have been developed in Japan and France, respectively. The principle of the chemical uranium enrichment was not known for many years. It was clarified 10 yeas ago that the origin of the uranium isotope effects was not in the molecular vibration but in the electron-nucleus interaction. Since then, attention has been placed on the similarities between the isotope effects in chemical exchange reactions and the isotope shifts in atomic emission spectra. Study on the temperature dependence of the isotope separation factor was a key to separate the “electron effects” and “molecular effects”. In the present paper, experimental work on gadolinium isotope effects in amalgamation is presented and isotope effects of lanthanide elements and actinide elements are reviewed. Discussion is extended to the role and effects of “ f ” electrons of these elements. Non-proliferation is the most serious problem in nuclear technology development. The chemical exchange uranium enrichment has been regarded as the proliferation-resistant technologies. Chemical enrichment, of which development has been abandoned in Japan and France, could be reconsidered again among international nuclear technology communities.

    SEPARATION OF TRIVALENT MINOR ACTINIDES FROM LANTHANIDES BY THERMOSENSITIVE GELS INTRODUCING FUNCTIONAL LIGAND

    Solvent extraction technique is applicable widely to the nuclear wastes

    treatment, for example the reprocessing of spent nuclear fuel and the recovery of long-lived nuclides from the high-level liquid wastes. However, large amounts of secondary wastes are generated by the operation of these solvent extraction processes. Recently, we proposed a new zero-emission separation process using thermosensitive gel instead of solvent extraction process, which is applicable to the partitioning and transmutation (P&T) system of trivalent MAs (minor actinides) in HLW (high-level wastes). Functional ligands are introduced in the polymer network of thermosensitive gel. A thermosensitive polymer gel is shrunken above LCST (Lower critical solution temperature) and swollen below LCST. Such volume change of thermosensitive gel is well known as the volume phase transition phenomena. Then, the complex formation of specific metal ion is controlled by the structural change of functional ligand with the volume phase transition of thermosensitive gel. The selective extraction of object metal is done by the thermal-swing operation and then no chemicals are required for elution. Secondary wastes are not generated principally from the thermal-swing extraction process.

    Firstly, the authors synthesized some thermosensitive NIPA (N-isopropylacrylamide) gels with a phosphoric acid ester and a BTP (2,6-di(3-vinylbenzyl-1,2,4-triazol-5-yl)pyridine) as functional ligands and tested the thermal-swing extraction of heavy metals, such as lanthanide, actinide and transient elements. The object metals were recovered successfully by these gels, but the difference in the distribution ratios of these metals between the swelling state and the shrinking one of gel was less than 5 times. The further increase in the difference of distribution ratios is required for the establishment of practical process.

    Recently, the separation of trivalent minor actinides (MAs) from lanthanides was investigated by a thermosensitive NIPA gel introducing a hexadentate ligand, TPEN (N,N,N',N'-tetrakis(2-pyridylmethyl)ethylenediamine) derivative. The obtained gel showed clear thermosensitivity with the volume phase transition at 34°C. The separation of a trivalent MA, Am(III), from a lanthanide, Eu(III), was observed in the swelling state of gel (5°C) and the separation factor of Am(III) was evaluated as about 18 at pH5.2. The distribution ratio of Am(III) was reduced to about 1/8 by the volume phase transition from the swelling state (5°C) to the shrinking one (40°C). These results suggest that Am(III) can be separated and recovered effectively from Eu(III) in aqueous nitrite solution without the generation of secondary wastes under the thermal-swing extraction operation using the thermosensitive gel.
