The MRS Symposium Proceeding series is an internationally recognised reference suitable for researchers and practitioners. This 2003 volume focuses on experimentally validated multiscale modeling of ductile metals and alloys.
In the past twenty years, new experimental approaches, improved models and progress in simulation techniques brought new insights into long-standing issues concerning dislocation-based plasticity in crystalline materials. Dislocation dynamics simulations are becoming accessible to a wide range of users. This book presents to students and researchers in materials science and mechanical engineering a comprehensive coverage of the physical body of knowledge on whichthey are based. This includes classical studies, which are too often ignored, recent experimental and theoretical advances, as well as a discussion of selected applications on various topics.
The measure of a thermoelectric material is given by the material's figure of merit. For over three decades the best thermoelectric materials had a ZT = 1. Recently, however, there are reports of new methods of materials synthesis that result in improvements beyond this performance. In addition, rapid characterization, as well as faster theoretical modeling of thermoelectric materials, has resulted in a more rapid evaluation of new materials. This book offers a look at these results and provides a benchmark for the current state in the field of thermoelectric materials research and development. The focus is on new and innovative directions that will lead to the next generation thermoelectric materials for small-scale refrigeration and power generation applications. The book emphasizes the multidisciplinary nature of the research needed to advance the science and technology of the field. Both theoretical and experimental studies are featured. Topics include: low-dimensional systems and nanocomposites; devices; oxides; skutterudites; complex bulk materials and measurements; novel approaches; and thermoelectric materials and technology.
This book focuses on recent advances in nanostructured and nanophase materials and their applications. Nanostructured materials consist of domains of less than 100nm and include atom clusters and cluster assemblies, one- and two-dimensionally modulated layers and three-dimensional structures. The term 'nanophase' refers to structures comprised of domains or particles of a single material that are typically less than 100nm, whereas 'nanocomposite' refers to a composite of more than one nanophase. Nanoscale materials can be engineered as homogeneous or porous ceramics, metals, metal oxides, semiconductors, organic polymers, or as composite materials containing these components. This book brings together scientists from many disciplines to share and discuss advances in the field. Topics include: nanophase materials; nanocomposite materials; nanoporous materials; nanostructured materials; applications and properties of nanostructured materials; carbon nanotubes; nanostructured thin films and coatings; and theoretical and modeling studies of nanostructured materials.
Papers from a December 2003 symposium review and discuss the science and technology of nanostructured materials and nanocomposites, with special emphasis placed on the relationships between their fabrication, structure, strength, and ductility. Major themes are nanoscience and nanoengineering of bulk and composite materials, thick coatings, and thin films with enhanced mechanical properties for structural and functional applications. The book will be of interest to researchers and graduate students in nanostructured materials science, and for engineers involved in the production and processing of nanocrystalline materials and nanocomposites for structural and functional applications.

The field of organic semiconductors has seen much development in the past years. Displays based on light-emitting diodes made of small organic molecules as well as polymers, have recently been commercialized. Other applications, such as electronic circuits for tagging, efficient photovoltaic devices and biosensors, have already been demonstrated. This volume brings together a "wish list" of leading researchers in the fields of chemistry, physics and technology of organic devices. Novel device concepts such as charge-generation layers, metal complexes and the use of heterojunctions are presented and should lead to further improvement in the efficiency of organic light-emitting diodes. In the field of organic transistors, major progress is reported on the charge-transport properties of organic semiconductors; mobilities up to 5cm2/Vs are reported for pentacene-based transistors. High mobility n-type materials, which enable the development of ambipolar organic electronic circuits, are also discussed. And new approaches to fully printable displays on substrates, such as textiles and paper, are presented. These may lead the way to new applications of organic optoelectronic devices.
Continued interest in the field of biologically inspired materials is strongly motivated by the fact that the nanoscale and microscale organization found in biological materials often leads to exceptional macroscopic materials properties. The ability to mimic these structures should lead to new synthetic materials with similarly remarkable behavior in both biomedical and materials arenas. This has led to an enormous amount of research in a variety of materials areas, including those aimed at: 1) unique ceramics or composites for use in biomaterials, magnetic and optical applications; 2) self-assembled biopolymeric systems for use in biomaterials and biosensor applications; and 3) colloidal and amphiphilic systems for application in biomedicine, nanotechnology and biosensors. Accordingly, this volume brings together a broad range of researchers whose interests span the full breadth of biology, and in addition, those who find different inspiration in biology itself. For some, that inspiration is in the creation of new materials that have important biological (especially biomedical) applications. For others, it is the imitation of the behavior of a biological material, molecule or process that is of interest. Finally, with increasing frequency, researchers are drawing inspiration from the synthetic pathways that biology uses, exploiting these pathways, and modifying them chemically or genetically to make entirely novel molecules and materials. Biologically inspired materials is a rapidly evolving arena of materials science research, and the work presented here reflects recent advances and new perspectives in the field. Topics include: tissue engineering and biomaterials; novel biomimeticand bioinspired polymers; biomineralization, colloidal and templated materials; and amphiphilic membranes and surfaces.
