The concepts of the Jahn-Teller effect and vibronic coupling are
being applied to more and more systems in both chemistry and
physics. Aspects of structural chemistry such as the distortion of
the nuclear framework to a lower-symmetry conformation have
received an increasing attention, as well as the dynamics on the
coupled potential energy surfaces.
Atomic transport in solids is a field of growing importance in solid state physics and chemistry, and one which, moreover, has important implications in several areas of materials science. This growth is due first to an increase in the understanding of the fund amentals of transport processes in solids. Of equal importance, however, have been the improvements in the last decade in the experi mental techniques available for the investigation of transport phenomena. The advances in technique have stimulated studies of a wider range of materials; and expansion of the field has been strong ly encouraged by the increasing range of applied areas where transport processes play an essential role. For example, mass transport phenomena play a critical role in the technology of fabrication of components in the electronics industry. Transport processes are involved both during the fabrication and operation of devices and with the growing trend to miniaturisation there are increasing demands on accurate control of diffusion processes. The present book (which is based on a NATO sponsored Advanced Study Institute held in 1981 at Lannion, France) aims to present a general survey of the subject, highlighting those areas where work has been especially active in recent years.
The understanding of hydrogen/lithium insertion phenomena is of great importance for the development of the next generation of functional electrochemical devices such as rechargeable batteries, electrochromic devices, and fuel cells. This volume introduces a variety of viable electrochemical methods to identify reaction mechanisms and evaluate relevant kinetic properties of insertion electrodes. The authors also outline various ways to analyze anomalous behaviour of hydrogen/lithium transport through insertion electrodes.

This volume contains studies on the molecular organisation on interfaces and nanoparticles. The contributions were presented during the 40. General Meeting (Hauptversammlung) of the Kolloid-Gesellschaft in Potsdam in September 2001 and are related to the subject "Colloids and Life Science." Therefore, a diversity of papers were collected covering a large field: synthesis of polymer colloids, biominerals and nanoparticles, investigations on monolayers, lyotropic mesophases, polymeric surfactants, micellar transitions, supramolecular compounds for modifying polymers, solid particles for emulsion stabilisers, and adsorbents for odour control.
This volume includes 20 contributions of the 12th meeting on Analytical Ultracentrifugation from March 1-2, 2001 in Duisburg, Germany. Various fields of ultracentrifugation are covered concerning research problems in biochemistry, biophysical chemistry and macromolecular chemistry as well as interacting systems. New investigations concerning the sedimentation theory are presented. The phase transition of gels is dealt with, as is the sedimentation-diffusion equilibrium of gels. One section contains the hydrodynamics of biopolymers.
Concepts of nonlinear physics are applied to an increasing number of research disciplines. With this volume, the editors offer a selection of articles on nonlinear topics in progress, ranging from physics and chemistry to biology and some applications of social science. The book covers quantum optics, electron crystallization, cellular or flow patterns in fluids and in granular media, biological systems, and the control of brain structures via neuronal excitation. Chemical patterns are looked at both in bulk solutions and on surfaces in heterogeneous systems. From regular structures, the authors turn to the more complex behavior in biology and physics, such as hydrodynamical turbulence, low-dimensional dynamics in solid-state physics, and gravity.
This is the first book on mathematical simulation on glass technology, and covers all production steps of special glass manufacturing. The enclosed CD-ROM shows 27 simulations of different aspects, such as surprising details of the pressing and casting process.

This volume contains the Proceedings of the Third International EXAFS Conference, hosted by Stanford University and the Stanford Synchrotron Radiation Laboratory on July 16-20, 1984. The meeting, co-chaired by Professors Arthur Bienenstock and Keith Hodgson, was attended by over 200 scientists representing a wide range of scientific disciplines. The format of the meeting consisted of 51 invited presenta tions and four days of poster sessions. This Proceedings is a compilation of 139 contributions from both invited speakers and authors of contributed posters. The last ten years has seen the rapid maturation of x-ray absorption spectrosco pyas a scientific discipline. The vitality of the field is reflected in the diver sity of applications found in the Proceedings. Recent work continues to probe the limits of x-ray spectroscopy, with proven techniques being extended to, for examp le, very low or high energy studies, to very dilute systems, and to studies of surface structure. In fact, the title of the conference does not at all reflect the breadth of the science discussed at this meeting. The number of fields in which x ray absorption spectroscopy is finding applications has increased dramatically even in the two years since the previous International Conference held in Frascati*. The prospects for continued growth and innovation will be even further enhanced if a new generation 6 GeV storage ring is constructed in the next five years."
This book provides tools well suited for the quantitative
investigation of semiconductor electron microscopy. These tools
allow for the accurate determination of the composition of ternary
semiconductor nanostructures with a spatial resolution at near
atomic scales. The book focuses on new methods including strain
state analysis as well as evaluation of the composition via the
lattice fringe analysis (CELFA) technique. The basics of these
procedures as well as their advantages, drawbacks and sources of
error are all discussed. The techniques are applied to quantum
wells and dots in order to give insight into kinetic growth effects
such as segregation and migration. In the first part of the book
the fundamentals of transmission electron microscopy are provided.
These are needed for an understanding of the digital image analysis
techniques described in the second part of the book. There the
reader will find information on different methods of

The author presents in detail a new non-perturbative approach to the fermionic many-body problem, improving the bosonization technique and generalizing it to dimensions "d">1 via functional integration and Hubbard--Stratonovich transformations. In Part I he clearly illustrates the approximations and limitations inherent in higher-dimensional bosonization and derives the precise relation with diagrammatic perturbation theory. He shows how the non-linear terms in the energy dispersion can be systematically included into bosonization in arbitrary "d," so that in "d">1 the curvature of the Fermi surface can be taken into account. Part II gives applications to problems of physical interest. The book addresses researchers and graduate students in theoretical condensed matter physics.
Epoxy resins are regarded as thermosetting resins and have found various c- mercial applications after crosslinking with adequate curing agents [1-3]. H- ever, some epoxy resins have been used as thermoplastic resins without curing agents. Figure 1 shows the applications of epoxy resins that are classi?ed to three categories: thermosets in combination with curing agents, thermoplastics wi- out curing agents, and raw materials for modi?cation. The use in thermoplastics is not popular compared with the two other applications. Typical thermoplastic applications are found in stabilizers for vinyl resins, toners for copying - chines, ?re retardants for engineering plastics, and sizing material for glass or carbon ?bers. The epoxy resin most frequently used is the oligomer of the diglycidyl ether of bisphenol-A (DGEBA) whose chemical structure is shown below [1-3]. The DGEBA is composed of linear molecules with different molecular weights according to the variation of the repeated number (n) in the structural formula.
Molecular manipulation of nano- and microstructures paves the way to produce organic polymer materials by design. Such architectures comprise both the synthesis and the kinetics and thermodynamics of macromolecular organization and is the theme of this volume. The book consists of four articles reviewing living polymerization to produce precisely defined linear polyesters, comparing them to other living polymerization techniques. The articles also deal with the synthesis of polymeric dendrimers, either by the convergent or divergent approach; block copolymers synthesis, to define micromorphology in high performance polymers; and thereby tailoring their thermal, chemical, mechanical and dielectrical properties, and finally kinetics and thermodynamics for microstructural organization in macroporous thermosets.
This review shows that the measurement of viscoelastic properties is a powerful tool in the study of thermoreversible gels. Although many conclusions may be drawn about network development and its structure, it is also shown that the use of additional techniques (e.g. small angle S-ray and neutron scattering techniques and optical rotation) and the combination with thermodynamics and network models, widens the insight in the crosslinking process and the gel structure temendously. A general Introduction is followed by eight Chapters concerning synthetic polymers (PVC, PVAL, PMMA, PS, PAN, PE, ABA blockcopolymers and LCP's) and four Chapters concerning biopolymers (gelatin, agarose, carrageenans and gellan gum).
The problem of moment formation in metallic systems lies at the interface of localized and itinerant magnetism. The phenomena observed correspond to destruction rather than to formation of spin-correlations. They give rise to the progression from local ized ground states through Kondo and mixed-valence behaviour to itinerant magnetic or non-magnetic systems. Somewhere in the pro gression superconductivity can occur in the presence of f-moments. To bring together the disparate ideas and methods, previously the subject of intense debate only at a number of topical confer ences, a two-week Advanced Study Institute was held August 21 - September 02, 1983, at Lester B. Pearson College of the Pacific, Vancouver Island. In the stimulating environment provided by the pines and fiord at the site of this remote United World College on the Canadian West Coast, scientists and students from around the globe gathered to hear lectures by experts. The Study Institute involved seventy-six people and followed in the tradition . of pre vious "Banff" summer schools organized by the Canadian Association of Physicists. It was made possible by grants from the North Atlantic Treaty Organization, the Natural Sciences & Engineering Research Council of Canada and Atomic Energy of Canada. The grants permitted many young scientists from Nato and non-Nato countries to learn the fundamentals as well as the latest results in the field."
This comprehensive series covers the science and technology of zeolites and all related microporous and mesoporous materials. Authored by renowned experts, volume 3 deals with the most widely employed techniques for the post-synthesis modification of molecular sieves.
