Download or read book Thermodynamic and Kinetic Aspects of the Vitreous State written by S.V. Nemilov and published by CRC Press. This book was released on 2018-01-18 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book to logically present the major problems of the vitreous state within the framework of irreversible thermodynamics. Filled with elementary explanations for difficult problems, this easily understood text/reference treats in detail the criteria of glass transition, the peculiarities of relaxing structural parameters, and the Prigogine-Defay ratio. Based on the author's rigorous generalization of the Second Law for non-equilibrium, the book systematizes all known thermodynamic data for glasses and melts. The thermodynamic essence of structural relaxation and memory effects are considered. The viscous flow theories are treated as a constituent of the kinetic description. All theoretical questions are illustrated by comparison of calculations with the experiments for glasses of inorganic and organic nature, with special attention to structural classification. An informative review of modern structural investigations is included. The bibliography follows the history of the main problems from the nineteenth century.

Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the experimental evidence and modern classical and theoretical approaches in understanding the vitreous state, from structural problems, over equilibrium and non-equilibrium thermodynamics, to statistical physics. Glasses, and especially silicate glasses, are only the best known representatives of this particular physical state of matter. Other typical representatives include organic polymer glasses, and many other easily vitrifying organic and inorganic substances, technically important materials, amidst them vitreous water and vitrified aqueous solutions, and also many metallic alloy systems. Some of these systems only form glasses under particular conditions, e.g. through ultra-rapid cooling. This book describes the properties and the formation of both every-day technical glasses and especially of such more exotic forms of vitreous matter. It is a unique source of knowledge and new ideas for materials scientists, engineers and researchers working on condensed matter. The new edition emphasizes latest experimental findings and modern theories, explaining the kinetics of glass formation, the relaxation and stabilization of glasses and their crystallization in terms of new models, derived from the framework of the thermodynamics of irreversible processes. It shows how the properties of common technical glasses, window glass, or the vitreous ice kernel of comets can be used to develop a new understanding of the existence of matter in various, unusual forms. The described theories can even find application for the description of lasers and interesting unusual processes in the universe.

Available in PDF, EPUB and Kindle. Book excerpt: The present book is devoted to problems of a physically important state of condensed matter - the vitreous state. We tried to summarize here the experimental evidence and the different theoretical approaches - structural, thermodynamic and those of statistical physics - connected with the formation, the kinetic stability and with the general nature of glasses as a particular physical state. In addition, a summary is given on the information available concerning proces ses of nucleation and crystallization of glass-forming systems, on methods of preventing or, in contrast, catalyzing crystallization in vitrifying liquids, on the kinetics of nucleation, the modes of crystal growth in undercooled melts and the devitrification of glasses. It was our aim to summarize in the present volume the basic principles and the most significant developments of a newly emerging science - glass science - and to show that, at least, in principle, any substance can exist in the vitreous state. Moreover, we have tried to demonstrate that the characteristic properties of the vitreous state may be attributed under certain conditions not only to systems with an amorphous structure (like the common glasses) but also to a number of other states of condensed matter including the crystalline one.

This book was released on 1993-03-15 with total page 992 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book differs from its predecessor, Lieb & Mattis Mathematical Physics in One Dimension, in a number of important ways. Classic discoveries which once had to be omitted owing to lack of space — such as the seminal paper by Fermi, Pasta and Ulam on lack of ergodicity of the linear chain, or Bethe's original paper on the Bethe ansatz — can now be incorporated. Many applications which did not even exist in 1966 (some of which were originally spawned by the publication of Lieb & Mattis) are newly included. Among these, this new book contains critical surveys of a number of important developments: the exact solution of the Hubbard model, the concept of spinons, the Haldane gap in magnetic spin-one chains, bosonization and fermionization, solitions and the approach to thermodynamic equilibrium, quantum statistical mechanics, localization of normal modes and eigenstates in disordered chains, and a number of other contemporary concerns.
Download or read book Treatise on Solid State Chemistry written by N. Hannay and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 788 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last quarter-century has been marked by the extremely rapid growth of the solid-state sciences. They include what is now the largest subfield of physics, and the materials engineering sciences have likewise flourished. And, playing an active role throughout this vast area of science and engineer ing have been very large numbers of chemists. Yet, even though the role of chemistry in the solid-state sciences has been a vital one and the solid-state sciences have, in turn, made enormous contributions to chemical thought, solid-state chemistry has not been recognized by the general body of chemists as a major subfield of chemistry. Solid-state chemistry is not even well defined as to content. Some, for example, would have it include only the quantum chemistry of solids and would reject thermodynamics and phase equilibria; this is nonsense. Solid-state chemistry has many facets, and one of the purposes of this Treatise is to help define the field. Perhaps the most general characteristic of solid-state chemistry, and one which helps differentiate it from solid-state physics, is its focus on the chemical composition and atomic configuration of real solids and on the relationship of composition and structure to the chemical and physical properties of the solid. Real solids are usually extremely complex and exhibit almost infinite variety in their compositional and structural features.

Download or read book Inorganic Polymeric Glasses written by Richard C. Ropp and published by Elsevier. This book was released on 2013-10-22 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: The author describes a novel method of preparing hydrolysis-stable non-silicate glasses which is based on experimental work accomplished over the past twenty years. As such, the method is the beginning of a new approach to glass-making by the use of a molecularly-polymerizable precursor. The book elucidates the technical details required to produce such molecularly-polymerized glasses from carefully prepared inorganic molecular monomers. Essentially, only silicate-based glasses have been known to be stable, whereas non-silicate glasses could not be attributed with such properties. Such glasses have, therefore, not found widespread usage in industry. The new phosphate glasses described here exhibit stabilities superior to many of the silicate glasses. For example, the nuclear-waste glass shows no measurable loss at all in boiling water, something entirely foreign to the zinc borosilicate glasses developed for nuclear waste encapsulation in the U.S. by Battelle-Northwest. The exceptional stability of the new glasses is achieved by selecting an inorganic compound capable of being polymerized, and then causing it to polymerize in a proper manner, in the absence of chain-stoppers. To obtain glasses equal or superior in hydrolysis stability to silicate-based systems it is imperative to employ molecular polymerization in situ, starting from carefully prepared precursors of exact stoichiometric proportion. Researchers in glass and glass properties will find this volume extremely useful and those involved in organic polymers will be intrigued by the similarities and disparities of the two systems.
Download or read book Advances in Materials Characterization written by David R. Rossington and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 666 pages. Available in PDF, EPUB and Kindle. Book excerpt: The characterization of materials and phenomena has historically been the principal limitation to the development in each area of science. Once what we are observing is well defined, a theoretical analysis rapidly follows. Modern theories of chemical bonding did not evolve until the methods of analytical chemistry had progressed to a point where the bulk stoichiometry of chemical compounds was firmly established. The great progress made during this century in understanding chemistry has followed directly from the development of an analytical chemistry based on the Dalton assumption of multiple proportions. It has only become apparent in recent years that the extension of our understanding of materials hinges on their non-stoichiometric nature. The world of non-Daltonian chemistry is very poorly understood at present because of our lack of ability to precisely characterize it. The emergence of materials science has only just occurred with our recognition of effects, which have been thought previously to be minor variations from ideality, as the principal phenomena controlling properties. The next step in the historical evolution of materials science must be the development of tools to characterize the often subtle phenomena which determine properties of materials. The various discussions of instrumental techniques presented in this book are excellent summaries for the state-of-the-art of materials characterization at this rather critical stage of materials science. The application of the tools described here, and those yet to be developed, holds the key to the development of this infant into a mature science.

Available in PDF, EPUB and Kindle. Book excerpt: Solid state physics after solving so successfully many fundamental problems in perfect or slightly imperfect crystals, tried in recent years to attack problems associated with large disorder with the aim to understand the consequences of the lack of the long-range order. Semiconductors are much more changed by disorder than metals or insulators, and appear to be the most suitable materials for fundamental work. Considerable exploratory work on amorphous and liquid semiconductors was done by the Leningrad School since the early fifties. In recent years, much research in several countries was directed to deepen the understanding of the structural, electronic, optical, vibrational, magnetic and other proper ties of these materials and to possibly approach the present level of under standing of crystalline semiconductors. This effort was stimulated not only by purely scientific interest but also by the possibility of new applications from which memory devices in the general sense are perhaps the most challenging. The research met with serious difficulties which are absent in crystals.

Download or read book Fundamental Phenomena in the Materials Sciences written by L. J. Bonis and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume explores in detail the four interrelated branches of the study of surface phenomena-surface thermodynamics, nucleation, diffusion, and fine-particles technology-providing an unusual and comprehensive body of knowledge that will be of interest and practical value to both materials researchers and practising engineers. The growing awareness-since the advent of the space age-among solid-state physicists, metallurgists, ceramists, chemical engineers, and mechanical engineers of the need for a broad interdisciplinary under standing of the fundamental phenomena common to all matedals has led in recent years to the development of a new field of scientific investigation, Materials Science. To help promote interest in and con tributions to this new technology, annual symposia on "Fundamental Phenomena in the Materials Sciences" have been organized by the Ilikon Corporation. The first symposium, reported in Volume 1 of this series, was held in Boston, Massachusetts, on February 1 and 2, 1963; sintering and plastic deformation were the main topics of discussion. The second meeting, also held in Boston, on January 27 and 28, 1964, was exclusively concerned with the general interdisciplinary problems related to surface phenomena, that is, all of those physical and chemical areas that are pertinent to the surface of a solid, or to the interface between a solid and a gas, a solid and a liquid, or a solid and a solid.
