This work includes information and formulae on adhesion related matters such as driving force formulae for various modes of delamination and methods for estimating stress buildup.
Описание: The sol-gel method is known to produce materials from solutions either in bulk, coating films, fibers or powders. It is also known that this method makes low temperature processing of materials possible. This technology has dramatically grown in these two or three decades. Sol-Gel Science and Technology covers optical, electronic and magnetic, chemical, mechanical, biomedical and biotechnological materials. Concerning the microstructures, the sol-gel method applies to porous materials, dense materials like glasses and ceramics, organic-inorganic hybrids and nanocomposites. The four volumes of this reference treat four areas that are timely, important and seeing great research activity: -Sol-gel prepared ferroelectrics and related materials. -Sol-gel processing of titanium oxides: photocatalyst and other applications. -Sol-gel prepared organic-inorganic hybrids and nanocomposites. -Sol-gel processing of porous materials: application to catalysts, enzymes, chemical analysis, sensors, and membranes. The goal of these four volumes is to disseminate the recent research results published in recent issues of Journal of Sol-Gel Science and Technology, which is a unique journal devoted to Sol-Gel. Papers have been selected from those published in volumes 16-25 of the Journal of Sol-Gel Science and Technology spanning the years 1999-2002. Volume 1 presents papers on preparation, structure, properties and applications of ferroelectrics and related materials, such as, piezoelectric and pyroelectric materials. Representative ferroelectric materials include BaTiO3, Pb(Ti,Zr)O3, PbTiO3, LiNbO3, KNbO3, LiTaO3, and Pb(ZnNb)O3. Generally, these materials have a high dielectric constant and are characterized by large piezoelectric, pyroelectric and electrooptic effects as well as nonlinear optical effects. On the basis of these unique properties, ferroelectric materials have been applied to produce active elements of various devices. Volume 2 contains papers on sol-gel processing of titanium oxides for photocatalyst and other recent applications. Titanium dioxide, TiO2, is both an old and new material with a variety of interesting functions. Conventionally, TiO2 was used mainly as light-scattering particles in porcelain enamel, ceramic glaze, white points and the suspension-type eraser. A more recent application of similar nature is the incorporation of TiO2 into UV- shielding cosmetics, which protect human skin from UV damage. TiO2 is also employed as nucleating agent for crystallization of glass, providing glass-ceramics. Papers on sol-gel prepared organic-inorganic hybrids and nanocomposites are compiled in Volume 3. Typical organic-inorganic hybrids have a microstructure in which inorganic species like -Si-O-Ti-O- are combined with organic polymers like polymethylmethacrylate chains at the molecular level. Volume 4 compiles papers on the gel as porous material. Porous gels with nano-size pores and micron-size pores are applied to formation of catalysts, enzymes, chemical analysis, sensors and membranes. Pore surfaces are significant because they serve as the absorption and reaction site for catalysts, enzymes, chemical reaction, and sensing molecules or atoms.
Описание: Within this text, for the first time the synthesis, structural characteristics, physical properties, applications and potential applications of polysiloxanes, polycarbosilanes, polysilazanes, polysilanes, and other silicon-containing polymers are detailed. For years to come this book will be the first point of entry for those seeking to learn about the very significant differences that exist between carbon-based polymers and those with silicon in their backbone.
Описание: This book gives an up-to-date introduction to the structure, physical properties and applications of quasicrystalline alloys. It covers quasiperiodic tilings and the determination and modelling of the atomic structure of quasicrystals. The electronic properties, determined from measurements of the partial electronic density of states and the calculation of the electronic structure, play a key role in this introduction, as does an extensive discussion of the determination and simulation of the atomic dynamics. For the application of these aperiodic crystals, defects are a critical issue. Thus the book also presents a detailed treatement of the study of defects in quasicrystals by high resolution electron microscopy and ion channeling, as well as computer simulations of defects and fracture in decorated tilings.
Описание: The field of charge conduction in disordered materials is a rapidly evolving area owing to current and potential applications of these materials in various electronic devices.

Описание: Contains a brief review of adsorption history and its development for practical purposes. This book presents important information on adsorbents and catalysts as well as on the methods of their characterization. It includes a comprehensive review on contemporary utility of self-assembled monolayers, adsorption proteins and their role in industry.
Описание: This book is based on the analogy between contact mechanics and fracture mechanics as proposed by the author about twenty years ago. It starts with a
chapter devoted to the surface energy and tension of solids and surface thermodynamics, which is followed by a chapter on elastic recall. The methods of Muskhelichvili and Hankel
transforms for the resolution of plane and axisymmetric problems are studied.
Then the essential conepts of fracture mechanics are presented with emphasis on the
thermodynamic aspect of the problem. The reader will find complete analytical results and detailed calculations for cracks submitted to pressure distributions and the Dugdale model, as
well as a chapter on contact mechanics. The contact and adherence of rough solids is also studied.
This book is intended for advanced students and researchers working in
the fields of fracture mechanics or adhesion.
Описание: Specifically dedicated to polymer and biopolymer systems, Polymer Adhesion, Friction, and Lubrication guides readers to the scratch, wear, and lubrication properties of polymers and the engineering applications, from biomedical research to automotive engineering.
Описание: Metallic (magnetic and non-magnetic) nanocrystalline materials have been known for over ten years but only recent developments in the research into those complex alloys and their metastable amorphous precursors have created a need to summarize the most important accomplishments in the field. This book is a collection of articles on various aspects of metallic nanocrystalline materials, and an attempt to address this above need. The main focus of the papers is on the new issues that emerge in the studies of nanocrystalline materials, and, in particular, on (i) new compositions of the alloys, (ii) properties of conventional nanocrystalline materials, (iii) modeling and simulations, (iv) preparation methods, (v) experimental techniques of measurements, and (vi) different modern applications. Interesting phenomena of the physics of nanocrystalline materials are a consequence of the effects induced by the nanocrystalline structure. They include interface physics, the influence of the grain boundaries, the averaging of magnetic anisotropy by exchange interactions, the decrease in exchange length, and the existence of a minimum two-phase structure at the atomic scale. Attention is also paid to the special character of the local atomic ordering and to the corresponding interatomic bonding as well as to anomalies and particularities of electron density distributions, and to the formation of metastable, nanocrystalline (or quasi-crystalline) phases built from exceptionally small grains with special properties. Another important focus of attention are new classes of materials which are not based on new compositions, but rather on the original and special crystalline structure in the nanoscale.

Описание: This volume reviews the latest experimental and theoretical studies in the field of ZnO. The chapters reflect the topics that were discussed during the NATO Advanced Research Workshop, which brought together researchers from Nato countries, Russia, Ukraine, and Kazakhstan to encourage cross fertilization and wider dissemination of the advances in this important research field. Fundamental issues such as growth of ZnO, structural, optical and electric properties, the role of the hydrogen and more were discussed.
