This book provides the fundamental statistical theory of atomic transport in crystalline solids, that is the means by which processes occurring at the atomic level are related to macroscopic transport coefficients and other observable quantities. The cornerstones of the authors' treatment are (i) the physical concepts of lattice defects, (ii) the phenomenological description provided by non-equilibrium thermodynamics and (iii) the various methods of statistical mechanics used to link these (kinetic theory, random-walk theory, linear response theory etc.). The book is primarily concerned with transport in the body of crystal lattices and not with transport on surfaces, within grain boundaries or along dislocations, although much of the theory here presented can be applied to these low-dimensional structures when they are atomically well ordered and regular.

XXIVth International Congress of Pure and Applied Chemistry, Volume 3 contains lectures presented at the XXIVth International Congress of Pure and Applied Chemistry held at Hamburg, Federal Republic of Germany in September 1973. The book consists of papers discussing a wide range of subjects on pure and applied chemistry. The compendium has papers that deal with advances in solid-state chemistry, atomic and ionic transport in ionic crystals, and the thermodynamics and preparation of non-stoichiometric, nonmetallic compounds. The text also presents papers covering topics on the formation synthesis and some properties of phosphate compounds, the application of valence electron concentration in crystal chemistry, and Crystal chemistry and magnetic properties of 3d transition metal fluorides. Chemists will find the book very interesting.

Covering the latest research in alloy physics together with the underlying basic principles, this comprehensive book provides a sound understanding of the structural changes in metals and alloys -- ranging from plastic deformation, deformation dynamics and ordering kinetics right up to atom jump processes, first principle calculations and simulation techniques. Alongside fundamental topics, such as crystal defects, phase transformations and statistical thermodynamics, the team of international authors treats such hot areas as nano-size effects, interfaces, and spintronics, as well as technical applications of modern alloys, like data storage and recording, and the possibilities offered by materials design.

Materials in a nuclear environment are exposed to extreme conditions of radiation, temperature and/or corrosion, and in many cases the combination of these makes the material behavior very different from conventional materials. This is evident for the four major technological challenges the nuclear technology domain is facing currently: (i) long-term operation of existing Generation II nuclear power plants, (ii) the design of the next generation reactors (Generation IV), (iii) the construction of the ITER fusion reactor in Cadarache (France), (iv) and the intermediate and final disposal of nuclear waste. In order to address these challenges, engineers and designers need to know the properties of a wide variety of materials under these conditions and to understand the underlying processes affecting changes in their behavior, in order to assess their performance and to determine the limits of operation. Comprehensive Nuclear Materials, Second Edition, Seven Volume Set provides broad ranging, validated summaries of all the major topics in the field of nuclear material research for fission as well as fusion reactor systems. Attention is given to the fundamental scientific aspects of nuclear materials: fuel and structural materials for fission reactors, waste materials, and materials for fusion reactors. The articles are written at a level that allows undergraduate students to understand the material, while providing active researchers with a ready reference resource of information. Most of the chapters from the first Edition have been revised and updated and a significant number of new topics are covered in completely new material. During the ten years between the two editions, the challenge for applications of nuclear materials has been significantly impacted by world events, public awareness, and technological innovation. Materials play a key role as enablers of new technologies, and we trust that this new edition of Comprehensive Nuclear Materials has captured the key recent developments. Critically reviews the major classes and functions of materials, supporting the selection, assessment, validation and engineering of materials in extreme nuclear environments Comprehensive resource for up-to-date and authoritative information which is not always available elsewhere, even in journals Provides an in-depth treatment of materials modeling and simulation, with a specific focus on nuclear issues Serves as an excellent entry point for students and researchers new to the field

This volume contains the lecture notes of ten courses given at the XIV Latin American School of Physics (XIV LASP) which took place in Caracas, Venezuela, from the 10th to the 28th of July 1972. The LASP is held each year in a different Latin American country. Its purpose is to bring together young Latin American physicists at the doctorate level to attend lectures given by well known scientists. The participants are also invited to give seminars on their research work. The topics of the courses given this year were chosen according to the existent fields of interest in Latin America. Two of these courses, namely those covering astrophysics and biophysics were given in such a way as to be accessible to all par ticipants independently of their main field of interest. The XIV LASP has received financial support from institutions in Venezuela and abroad, making possible a meeting of ninety-two Latin American physicists and ten distinguished lecturers. For this we are indebted to the following Institutions: Consejo Nacional de Investigaciones Cientificas y Tecnologicas de Venezuela, Organization of American States, Instituto Venezolano de Investigaciones Cientificas, and its physicists, Universidad Central de Venezuela, Consejo de Desarrollo Cientifico y Humanistico de la U.C.V., Universidad Simon Bolivar, Embassy of U.S.A. in Venezuela, Embassy of France in Venezuela, The British Council in Venezuela, Ministerio de Educacion de Venezuela and the Latin-American Center of Physics.
