    A CHALMERS AREA OF ADVANCE AT CHALMERS AND GU BIOMATERIALS

    Materials Science

  • his booklet provides brief presentations of the research in the Area of Advance Materials Science in Gothenburg, a strong scientific community with special governmental funding. It includes research in materials science at Chalmers and at the Division of Biomaterials at Gothenburg University (GU). To provide a flavor of the activities we present the academic staff at Chalmers and GU Biomaterials engaged in the Area of Advance. The Area of Advance is based on five profile areas: Materials for health, Materials

    for energy applications, Sustainable materials, Experimental methods, and Theory and modeling. The first three profile areas are directed towards applications and grand challenges for the society while the two latter are generic, laying the foundation for breakthroughs in materials science.

    The researchers presented in the brochure are all active in one or more of the five profile areas. Together they perform cutting edge research with the aim to contribute to finding solutions to important challenges in the materials field such as:

    More materials must be based on renewable feedstock Construction materials must become lighter; lighter constructions save both energy and materials New and improved ways for supply, transport, storage and conversion of energy require innovative new materials

    Functional materials, i.e. materials that utilize the native properties and functions of their own to achieve an intelligent action, will become more important

    Regenerative medicine will put high demands on the materials involving both mechanical aspects and functionality

    The aim of the Area of Advance is to combine scientific excellence and relevance for society. It stretches from education on the master and PhD levels to innovation. It includes five departments at Chalmers and the Division of Biomaterials at Gothenburg University. There are several centers of excellence in materials science operating under the umbrella of the Area of Advance Materials Science and these centers normally have long term joint funding from the Swedish government and from a consortium of industries. The Centers for Catalysis, High Temperature Corrosion, Railway Mechanics, Supramolecular Biomaterials, and BIOMATCELL, as well as the Wallenberg Wood Science Center are all strong entities with ten years or longer funding.

Nanotoxicology: Major concerns have recently been directed towards the possible toxicity of nanomaterials. Within this research field we are focusing on how the properties of nanoparticles, such as size, shape, crystallinity and surface chemistry effects their toxicity and ability to penetrate biological barriers such as the skin.

    Engineering metals for demanding

    applications how to evaluate their performance?

    Some properties of engineering metals are inherent from the ele-ments they are composed of, for example stiffness and density. Other properties like strength and hardness can be tailored during material and component manufacturing. For estimates of the per-formance in the application, it is important to evaluate the material characteristics in the component and also consider the stability of properties during service, which often comprises high mechani-cal and thermal loads. A combination of testing and modelling is needed for the evaluation. The experimental work includes studies of monotonic and cyclic deformation behaviour and its relation to microstructure, temperature and strain rate. The results are used both for physi-cal interpretation of the material behaviour and used as input for numerical modelling of property development both in production

    Nanomaterials for Biological Applications

    We utilize nanochemistry to design nanomaterials for biological applications. Even though the field originates from the field of chemistry, the subject is highly multidisciplinary including biol-ogy, medicine and physics. Our research interests are: Bio-sensing: We are working on the development of a bio-sensing device, which utilizes ion channels as sensing elements. The device is based on a supported lipid bilayer that is covalently linked to a mesoporous support. Biomimetic synthesis: Inspired by nature, we are mimicking the natural bottom up fabrication approach of synthesizing structures on the nanometer length scale. In specific, we are synthesizing various types of calcium phosphates, titania and silica having designed nano-sized features. Regenerative medicine: In the field of regenerative medicine we are focusing on nanostructured implant surfaces both to increase

    and in service. Examples of research topics include: Railway wheel and rails steels exposed to a combination of ther-mal and mechanical loads. Aluminium engine blocks with cast-in, cast iron liners yielding residual stress fields that causes distorsions after machining.

    Polymer Technology

    A large part of the research in polymer technology is directed towards polymer electronics. A major advantage with polymer electronics is the ease by which the semiconducting polymers can be deposited. It is no more difficult than printing a color magazine! The idea of printed electronics is realized today. Not on a com-mercial full scale production, but on an advanced research level and the progress depends strongly on the development of new and better polymers. The aim with the research is mainly focused on the design and synthesis of new conjugated polymers for efficient and stable elec-tronics such as solar cells, photo diodes, light-emitting diodes, lasers, thin film field effect transistors, electrochemical devices, sensors and to relate the chemical structure of the polymer to the device performance. If successful, this research is not only scientifically interesting but can also result in for example cheap

    Detailed microstructure of materials

    We work with microscopy and microanalysis of primarily metal-lic materials using high-resolution methods such as atom probe tomography (APT) in combination with electron microscopy. 1. Design of new martensitic chromium steels for steam power plants. Todays steels have limited creep and oxidation resist-ance. In collaboration with the Technical University of Denmark, Siemens and DONG we explore new ways of hardening by boron additions (Paper 1) and nanometer-sized Z-phase precipitates. The aim is to increase the service temperature from 600 to 650C. This would increase the thermal efficiency by several percent and mean very large savings in CO emissions, since 70% of the worlds electricity is generated in fossil fueled steam power plants. 2. Interface structure and chemistry in cemented carbides. Inter-faces control e.g. sintering and plastic deformation behaviour of cemented carbides used for metal cutting operations. In collabo-

    solar cells and energy efficient lightning, which would be very beneficial for the environment and mankind. Another central part of the research in polymer technology is focused on bulk polymers. One important task within this field is focused on developing isolating materials for high voltage cables, mainly in cooperation with different companies in the Gothenburg region.

The former is utilized in studies of fundamental photonics (light-matter inter-actions) and photovoltaics. The latter allows for photochemistry enhancement and extremely high sensitivity towards the changes in the surrounding refractive index that serves as a basis for highly demanded label-free bio(chemo)sensing applications.

    Heterogeneous catalysis

    My research concerns design and studies of new catalyst-based concepts for environmental and sustainable energy applications including fundamental aspects on physicochemical processes in heterogeneous catalytic systems. I have adopted a research approach that balances chemistry, physics and chemical engineer-ing of both experimental and theoretical character suitable for heterogeneous catalysis research. I strive for cross-disciplinary collaborations as to join methods from traditionally different dis-ciplines with the overall aim to advance the field of transient in situ studies of catalytic reaction systems. This as to better under-stand mechanisms and basic principles behind activity, selectivity and durability for generic as well as more specialised catalytic processes. One recent example concerns characterisation of struc-ture-function relationships in methane oxidation over supported noble metals studied primarily at large-scale European research

    Functional optoelectronic nanomaterials

    Our current research explores functional bottom-up low-dimen-sional nanomaterials with highlight on nanophotonics, optical label-free biosensing, enhanced photochemistry/photovoltaics and nanomagnetism. Low-dimensional refers to ultra-thin nano-structured layers that are patterned on solid supports. Bottom-up emphasizes that such nanomaterials are produced by self-assembly driven nanofabrication, in particular by the method developed by us at Chalmers hole-mask colloidal lithography, HCL. Particular focus is on nanomaterials that support surface plas-mon polaritons (or localized surface plasmons, LSP) collective oscillations of the charge carriers, induced by the incoming electromagnetic radiation (thus optoelectronic nanomaterials). The excited LSP resonances exist in confined geometries like fabricated with colloidal lithography nanoarchitectures (arrays of nanodisks, nanoellipses, nanocones and many others) and

    facilities (ESRF/Grenoble, Petra III/Hamburg and MAX-lab/Lund). Time-resolved mass spectrometry with synchronous x-ray absorption and infrared spectroscopy or surface x-ray diffraction have been used in situ during transient conditions to correlate activity/selectivity with chemical state and physical structure of the catalyst surface as well as adsorbate composition.

    Material mechanics

    My research area is modeling of the mechanical behavior of the cyclic behavior of metals. Current research projects deal with modeling of applications such as steel components in the railway industry and superalloy components in gas-turbines subjected to thermo-mechanical fatigue loading. A focus area is the development of macroscopic models for steel that should capture, e.g., the cyclic ratcheting behavior and, for large strains, the evolution of anisotropy. Similar models can be used for superalloys subjected the high temperatures. But in this case we must also consider difficulties such as creep effects and the variation of temperature. Another focus area is multi-scale models for polycrystalline materials. In this modeling approach we typically model the grains by using crystal plasticity models and then use computational homogenization to obtain the macroscopic response. A specific

    Molecular Microscopy

    As an important instrument in the design of innovative materials with tailored surface and material properties, we develop and apply a new category of high-resolution microscopy techniques (CARS, SHG, THG, TERS ...) for tomographic, soft-matter imaging of the underlying macromolecular architecture by mapping inherent molecular vibrations of polymers, biomolecules (lipids, carbo-hydrates, structural proteins etc.) and metallic nanostructures. In far-field and near-field (with a scanning tip) modes a resolution of 300 nm and 30 nm, respectively, is achieved. It opens up for unique studies, where molecular distributions and processes can be studied at nanoscopic level and in their natural context without the impact of bulky fluorophores or harsh sample preparations. Examples of ongoing studies are (i) controlled release of active agents from polymer capsules, (ii) stem cell growth and differ-entiation in biomimicking materials for replacement tissues and

    Inorganic Materials focus on complex oxides

    The group has a long-standing tradition of research on complex oxides with main focus on perovskite and perovskite related compounds. Synthesis and development of preparative methods, and advanced structural characterisation are key activities. We are experienced in preparing high temperature superconducting cuprates, ferroic and magnetic materials as well as magnetolectric systems. Today a large part of our effort is devoted to exploring the emerging field of proton- and oxygen ion conducting materials, eventually for use as electrolytes in solid oxide fuel cells. Our aim is to acquire a better understanding of how oxygen and proton con-tent and local order can be linked to the ion conducting properties. This will help us to predict new systems, and act as feedback to the synthesis program. In-house laboratories include preparative facilities (e.g. solid

    Microstructures of Inorganic Materials

    My research is concerned with relationships between micro-structure and properties of, principally, hard structural materials. The research involves the application of different scanning and transmission electron microscopy techniques for imaging and microanalysis. The work covers three areas of materials sci-ence: (i) development and stability of nano-/microstructure, (ii) toughening and strengthening mechanisms, and (iii) deformation mechanisms. The development of nano-/microstructure under dif-ferent processing and testing conditions is characterized by high resolution imaging and microanalysis, and the results are related to different parameters in the fabrication process and to the behaviour of the material under mechanical and thermal load. A significant part of the research has been concerned with the development of fine-scale microstructure during sintering and crystallisation processes in ceramic and glass-ceramic materials.

In addition we are involved in the upgrade of two neutron powder dif-fractometers at the large-scale facility ISIS, Rutherford Appleton Laboratory, UK, and the design and implementation of a suite of sample environment cells. Unique in-situ studies are performed in the neutron beam to probe e.g. chemical reactions or fuel cell materials and batteries under real working conditions.

    Industrial Materials Recycling and Nuclear Chemistry

    I hold the view that my goal as a chemist in Industrial Materials recycling is to create new chemical processes for the recycling of that which is currently impossible (or difficult) to recycle. An important part of my work is to devise methods of recycling dif-ficult materials without causing a loss of quality of the material being recycled. The substances which I am interested in the recycling of include metals; precious metals (silver, gold and platinum group metals), base metals such as nickel, rare metals such as the lanthanides and radioactive metals such as americium. I also have an interest in the recycling of organic compounds (such as polymers) and non-metals such as chlorine, bromine and other main group elements. In addition to the recycling work I have an interest in the decontamination of waste to allow its cheap disposal while safeguarding human health and the environment.

    Structure property relationship

    in biopolymer based materials

    Biomimetic design requires an understanding of structure-property relationships at all length scales. The major interest is biomechani-cal behavior and cell response investigated by NMR. Structure and unique properties of biological materials such as bone, wood, cartilage, jelly-fish, and shells are the objects of my studies. In my research I use the principles of biomimetic design for the preparation of new materials using renewable building blocks. That includes biological fabrication through the use of enzymes, cells, and the coordination of biological systems. I am particularly interested in designing and preparing new biomate-rials which can replace or regenerate tissue and organs and have been working closely with cardiovascular surgeons to develop technology for the production of small calibre blood vessels. We use bacteria to spin nanocellulose fibrils which are assem-

    I am also involved in the Nuclear Chemistry section where I have an interest in a range of topics including the chemistry of serious reactor accidents, the organic chemistry of low and intermedi-ate level wastes (mainly isosaccharinic acids) and in advanced separations. I define nuclear chemistry as the chemistry associated with the nuclear fuel cycle, nuclear reactor operation, environmental radioactivity, radioactive waste, radiopharmaceuticals and other radioactive/nuclear technologies. My nuclear interests tend to be at the interface of this area with organic and inorganic chemistry.

    High Voltage Engineering

    We continuously seek innovative solutions within applications of different processes and materials in electro-technical industry, where material characterizations, simulations, technology and measurements are in focus. Three main areas dominate our activi-ties today, which include (i) applications of polymeric materials for insulation of high voltage apparatuses, especially for DC and high frequency stressed systems, (ii) simulations of electro-physical phenomena in dielectric and magnetic materials, as well as (iii) development of diagnostic measuring technologies for assessment of insulation state for prediction of its life time. Scientific and engineering problems are approached by combined experimental and theoretical methods and the research tasks are solved in a strong and multidisciplinary environment, including cooperation with other academic groups, with professional organizations like CIGRE and IEEE and with industrial partners in Sweden and

    Use of computational methods to find

    sustainable ways to produce and utilize energy

    My long-term goal is to find new or improved ways of how to produce and utilize energy without severely affecting the environ-ment. Research areas that I am working in include surface science, heterogeneous catalysis and materials for energy applications. I use several different computational methods, such as, density functional theory calculations, molecular dynamics, Monte-Carlo techniques, and micro-kinetic models. These multiscale meth-ods allow a transfer our understanding of the different processes involved at the atomic level to the realm of our macroscopic world. For instance, the activation of gas-phase reactants on surfaces can be directly linked to the actual output of a catalyst.

In continuation, an area of special interest is in developing polymeric materials that can stand higher operating stresses for optimizing design of cable insulation. New solutions where the desired prop-erties can be achieved include polymeric materials containing nano-fillers and voltage stabilizers.

    reusablility have been obtained in many cases. Interfaces are important for many enzymes. We have demon-strated that during the fat digestion process the lipase is pushed away from the triglyceride-water interface by one of the degrada-tion products, the monoglyceride, which is more interfacially active than the lipase itself. Recently we have studied trypsin entrapped in an alginate gel. We have found that the selectivity is dramati-cally changed when trypsin interacts with the alginate strands. We also study the action of trypsin on layer-by-layer structures made from oppositely charged polypeptides.

    Microstructure design of soft materials

    My research is focused on microstructure design of soft materi-als to tailor properties such as mass transport and rheological behaviour. This is on of the cornerstones of the SOFT Microscopy Centre as well as the VINN Excellence Centre SuMo biomateri-als. The main model systems are single and composite physical gels of proteins and polysaccharides where the structure can be tailored by the kinetic balance of the mechanisms involved. This requires structure control over a wide range of length scales as well as time scales. Combinations of microscopy techniques are being used from high-resolution transmission electron micros-copy to state of the art confocal laser scanning microscopy. New techniques are being developed for 3D reconstruction as well as microscopy of transient phenomena under dynamic conditions. Examples of model systems are beta-lactoglobulin, pectin, gela-tine, carrageenan, gels as well as composite gels of proteins and

    Surfactants and biomolecules at interfaces

    Our group has a long tradition of studying amphiliphilic com-pounds. In recent years the focus has been on cleavable surfactants, gemini surfactants and surfactants based on amino acids as polar headgroup. We carry out synthesis of the surfactants and we study their self-assembly both in solution and at interfaces. We have recently started to explore amphiphilic silica nanoparticles as stabilizers for emulsions. Hydrophilic and hydrophobic chains are grafted on the silica surface. We synthesize mesoporous materials and use these as hosts for homogeneous catalysts. We have used this concept for rho-dium complexes to perform carbon-carbon coupling reactions and we have used the porous materials for entrapment of lipase and trypsin. We have also used a slurry of mesoporous material with the catalyst embedded in the pore walls for hydroperoxide oxidation of an alkene. Excellent results in terms of activity and

    Theory of materials binding and function

    Computational theory of condensed matter faces a sparse-matter challenge. There is a clear need to develop and deepen our quan-tum-physical insight on the binding in regions with low electron and atom densities, sparse regions where the ubiquitous van der Waals (vdW) forces contribute significantly to cohesion and func-tion. Sparse-matter problems are generic, with examples ranging from nanostructured materials, over important surface-science phenomena, and to the very broad set of soft-matter and biomo-lecular systems. My research focuses on developments of the formally exact density functional theory (DFT) to more accurately describe sparse materials, primarily through our contributions to the inter-nationally recognized van der Waals density functional (vdW-DF) method (http://fy.chalmers.se/~schroder/vdWDF). Additional research components involve development of a nonempirical

    Lean NOx reduction

    My research activities focuses on environmental catalysis, and more specifically on lean NOx reduction, mainly for diesel- and lean-burn applications but also for alternatively fuelled vehicles. In catalysis research, fundamental knowledge about the chemical reactions occurring on the catalyst surface is a prerequisite for development of new and efficient catalyst materials and concepts .In particular design and preparation of catalysts as well as char-acterization and evaluation of these materials, including in-situ studies of reaction mechanisms and formation of surface bound intermediate species, have been performed. Recently, I have also started activities directed towards NOx reduction for ships, which is an emerging field owing to upcoming international legislations. My vision is to work with environmen-tal catalysis for energy efficient transportation, like bio-powered vehicles and ships. Both applications offer interesting and new

    Physics of functional oxide films and heterostructures

    The complex oxides embody a broad range of materials with the same characteristic perovskite crystal structure, ABO3, where A and B are usually alkaline and transition metals, respectively. They exhibit a rich variety of crystallographic, electronic and mag-netic phases and are hosts of new important phenomena, including high-temperature superconductivity, colossal magnetoresistance, multi-ferroic behavior, and many others. They often called func-tional oxides, because their electronic properties can be tuned by chemical doping, pressure, electric or magnetic field without changing the crystal structure. Our research is centered around polar oxide interfaces which are becoming a building block of oxide electronics. We fabricate various oxide thin films and interfaces of insulating, metallic, superconducting, ferroelectric and ferromagnetic materials.

    Materials Characterization

    To understand a materials structure, how that structure deter-mines its properties, and how that material will subsequently work in technological applications, we apply analytical electron microscopy (SEM, TEM) in combination with all necessary com-plementary techniques such as XRD, AES, XPS, DSC/TGA, etc. Particular focus is put on the development and characterization of different types of nanocrystalline and sub-microcrystalline materials (metallic, ceramic, and hybrids in a variety of sample forms) for functional applications. Corrosion- and wear resistance coatings as well as energy absorbing materials typically produced by electroplating or thermal spray techniques are investigated and optimized with respect to phase formation and texture, thermal stability, adhesion, etc. However, also structural materials like superalloys and advanced steels are investigated to improve their production and/or application.

    Polymers and controlled release

    Materials used to control the drug release are important to under-stand since they enable development of more efficient and safer medicines. My research focus is on polymers and designing for-mulations for controlled drug release. A special focus has been on cellulose and cellulose derivatives for oral controlled release, which can be achieved by creating barriers around reservoirs of the drug or by making drug containing hydrophilic matrixes that swells and erodes simultaneous. We have developed new advanced characterization methods that can explore the complex structure of cellulose derivatives and relate the structures of the polymers and the formulations to the drug release, water diffusion rates in the devices and polymer erosion rates. We have for example shown that the drug release rate from hydrophilic matrix tablets not only depends on the molar mass and the degree of substitution, but also on the substitution pattern along the cellulose chain.

    Ionic liquid derived materials

    Our research aims at developing ionic liquid (IL) based materials for use in low-temperature Fuel Cells and Li-ion batteries, which are interesting alternatives for a greener energy supply. We inves-tigate different ways to confine the ILs into solid matrices, like polymers (e.g. Nafion or PVdF) or silica networks (see ionogels), to meet the needs of shaping and solve safety issues. Thus, a central aspect in this research is to conceive solid-like electrolytes yet preserving liquid-like properties, such as high ion mobility and low viscosity. To reach this goal the solid-liquid interplay must be understood on the molecular level, both during synthesis and under operational conditions. Therefore, issues like connectivity of the solid network, local dynamics, and confinement effects become very important. From a more fundamental point of view, we aim at understanding the relation between molecular structure of the constituting ions and physical properties like ionic conductivity,

    Innovative energy conversion devices

    Development of electrochemical devices such as solar cells, fuel cells and rechargeable lithium batteries is the prime interest. This involves a broad range of measurements of electrical and ther-mal properties to develop and analyze materials with the desired properties. Photoelectrochemical solar cells based on natural or synthetic dyes and on quantum dots are developed in order to obtain stable and cost-efficient devices. Quantum dots are used in this applica-tion because their absorption spectrum is dependent on the size of the dots and could thus be tuned to a specific application or to enlarge the range of absorbed energy. Focus is on improving electrical properties and durability. Lithium-ion batteries are now generally considered for auto-motive use, nevertheless there are aspects of their use that need a deepened knowledge concerning material science. These issues

One prime example is oxideconducting materials that often have a substantial cation disorder whilst the associated oxygen vacancies are intrinsically ordered as well as clustered around specific cations. Such detailed knowledge about the local structural ordering is essential for a complete struc-tural understanding and for making new materials with improved properties. My research is focused on understanding the fundamental aspects of structural disorder and how it affects the physical prop-erties of a material. A main technique is neutron scattering with a focus on using and developing in-situ techniques for investigating chemical processes and physical properties whilst collecting dif-

    Controlled release from microparticles, paint and coatings

    Biocide-containing paint loses the protective ability quite rapidly due to fast diffusional biocide leakage. A promising improvement of anti-growth protection can be achieved by the use of encap-sulated biocides that slows down the diffusion in the coating. The biocide is placed into microparticles, from where it is slowly distributed into the surrounding coating matrix. My current research involves projects with both applied and fundamental focuses. I am part of the Marine Paint Programme, an interdisciplinary research collaboration with the aim to develop effective marine antifouling paints. Another application using microparticles is facade coatings. The research concerns the mechanisms that govern release from microparticles and the pos-sibility to apply mathematical models that may describe and predict release.

    fraction data. We also perform total scattering measurement which provides a total radial distribution function that can be analysed with the reverse Monte Carlo method. This results in information concerning order/disorder at the local atomic scale as opposed to methods that analyse the average structure. The development of in-situ cells for neutron powder diffrac-tion, e.g. in-situ cells for controlled oxygen pressure & impedance spectroscopy is part of an ongoing cooperation between Chalmers and the ISIS neutron facility, UK.

    Engineering metals for power conversion

    systems and surface analysis of their degradation

    The degradation of engineering metals in harsh environments oftenlimits the capability of technical systems. Increased temperaturesaffect the load capacity and induce accelerated corrosion that reduces the lifetime. My research focuses on materials in power conversion systems where higher temperatures significantly improve the energy efficiency and environmental impact of the system. Thorough studies of the material performance give a basis not only for alloy selection but also to identify relevant research questions. Studies of materials degradation on scales ranging from meter to nanometer are related to the material structure and the application. This is combined with lab exposures, often mimicking complex environments, and detailed characterization of the attack. In particular we use surface analytical tools like AES (Auger Elec-tron Spectroscopy) and XPS on both technical surfaces from the

    of PM materials and Advanced Alloys

    Powder metallurgy (PM) is one of the most energy efficient and materials utilization efficient ways of transforming a raw mate-rial into the final material in advanced products and components. The control of surface reactions during the processing of the PM material is of great importance and I have therefore taken special interest in advanced surface analysis such X-ray photoelectron spectroscopy (XPS) and Auger electron spectroscopy to study surface composition of metal powder and develop understanding of surface reactions during metal powder sintering. This includes studies of high strength sintered steels and recently also soft magnetic composites and shape memory metals. We try then to understand how to sinter to achieve good properties (see figure). We have also included thermodynamic and kinetics modeling, experimental simulations, FEM, etc in our approach.

    field, and on lab material. The general aim is a more efficient use of engineering metals in their application. The applications include waste and bio fuelled boilers where fuels, lowering the emissions of CO2, can cause severe corrosion of stainless steels. We did rather fundamental studies of the corrosion of cast steels and irons used in engines manifolds and now work on corrosion in exhaust systems where urea is injected to reduce the emissions. Fatigue of superalloys is studied primarily using the surface sensitivity and 12 nm lateral resolution of our Auger nanoprobe.

    Soft matter structure design for controlling diffusion and flow

    Soft biomaterial structure, dynamics and diffusion and flow are key words in my research. Soft biomaterials are of great soci-etal interest but our understanding of the principles governing transport of liquids and particles in liquids is still weak. Polymer and particle gels are two examples of soft biomaterials where the dynamics range from picosecond to years and the structure may vary between nano to millimeter making them highly challenging. My research deals with understanding the fundamental principles involved in the correlation between material structure and dynam-ics and the motion of particles or molecules. I colloborate with mathematicians, physicists, materials sci-entists and biologist in projects of both fundamental and applied nature. In the VINN Excellence Center SuMo Biomaterials (http://www.chalmers.se/chem/sumo-en/) we combine several scientific disciplines towards better understanding of soft biomaterials. We

    The functional structure of nanostructured materials

    The properties of materials are determined by the arrangements of atoms and electrons in phases, combined systems and artifi-cially made structures. The reason is that atoms are sufficiently close for each atom to simultaneously interact with several near-est neighbours at any given time in solid state and liquid matter. Consequently, defects and interfaces also have a strong influence on the properties. My research concerns the correlation between atomic structure and atomic structure and how they are related to the synthesis parameters. The knowledge provides both a fun-damental understanding for the material phenomena and also the ability to design new intelligent materials with tailored properties. The atomic structure is studied mainly using electron micros-copy and the electronic structure mainly using electron energy loss spectroscopy. The development of systems for dynamic in situ experiments by, for example, scanning probe microscopy in

I work with developing sustainable antifouling coating materi-als. In a short perspective it entails formulation of mixtures of biocides with microcapsules for controlled release. Looking many years ahead the goal is a new class of functional smart coatings that are completely biocide free and thereby sustainable from an environmental point of view.

    Emission cleaning from vehicles

    using heterogeneous catalysis

    It is crucial to decrease the emissions of toxic gases from vehicles and heterogeneous catalysis plays a vital role for this. The cata-lytic system after a diesel engine is today very complex. Most new catalysts are multi-component, with several active materials dispersed on a porous support. Real catalysts on a support are very heterogeneous and the outcome off the added materials is often far from the sum of the added functions. The interplay between differ-ent materials will influence the electronic promotion of the active materials, the number of sites in the border between the materials, spill-over processes, etc. These processes are crucial for the activ-ity and selectivity of the catalytic material. In my research group we focus on heterogeneous catalysis for cleaning emissions from vehicles. We synthesize catalytic materials and characterize them thoroughly. We also use micro calorimetry to determine the heat of

    Osseointegration: from macro to nano

    My research interest consists of evaluation and implementation of novel techniques for characterization of the bone-implant inter-face at different resolutions levels and aspects. Important factors are structural and chemical analysis with nanometer resolution and biomechanical evaluations at the macro level. By combining analysis at different length scales and aspects a more thorough understanding of the bone-bonding process could be retrieved generating more detailed knowledge for optimization of the sur-face structure, improving the early bone formation and long-term success. Implants are used to restore lost body functions, which might be due to trauma or decease. Since the 1960s titanium implants have been used for anchoring teeth and have shown excellent clinical results. The ability for a titanium implant to be anchored in bone tissue was termed osseointegration, and defined as a direct contact

    adsorption of gases on different surfaces and DRIFT spectroscopy to identify the adsorbed species on the catalyst. We combine all the experimental results in order to develop a detailed mechanism for what reaction steps occur on the catalytic surfaces and how the interplay between the materials affect the mechanisms as well as activity and selectivity. Based on this understanding we develop kinetic models that can describe the reactions that occur on the catalytic materials. The models can be used both for increasing the knowledge and for predictions.

    rheological properties and the manufacturing process also have a direct influence on the surface quality, not least for the generation of surface defects. Use of polymers based on renewable resources, instead of fossil-based ones, also constitutes an area of great inter-est. The use of such materials requires however in many cases an adaptation of the processing technique used and this represents an active research field for the group. A third important activity centres around electrical and other physical properties of nano-composites based on carbonaceous particles.

    Functional Materials Chemistry

    Our research is within the area of materials chemistry where we develop new functional materials and methods for their synthesis. We have expertise in studies of processes involved in the forma-tion of nanostructured materials, structural and physicochemical characterisation of materials and evaluation of their properties. Nanostructured materials. Much of our efforts are focused on nanostructured materials ranging from small particles to micro- and mesoporous solids and host-guest clathrates. These materials offer high interfacial areas and a diverse range of properties, and are of interest for many applications. Depending on structure and composition of the material we choose our synthesis methods from a broad range including amphiphile-directed wet chemical sol-gel methods, solvothermal, solid state mixing and crystal pulling using the Czochralski-method.

    Polymeric materials and composites

    Polymers constitute today a very important group of materials, although the plastics have only been around for a few decades. A distinctive feature of materials science is the search for useful relations between the structure (on different levels) and mate-rial properties. In the case of polymeric materials, the processing technique chosen has a very strong influence on the structure of the material and thus on its performance. These aspects constitute together the basis for the activities within the research group. The research is often of an interdisciplinary character and covers both fundamental and more applied issues. My specific interests are today focussed on the relations between surface characteristics of polymeric components, e.g. surface topography, colour and reflectance, and the perceived quality. This requires fundamental knowledge on the scattering proper-ties of surfaces as well as the use of human test panels. Here the
