  • Catastrophe Theory

    • 1 Edición
    • Volumen 33
    • A. Okninski
    • Inglés
    This book aims to provide a straightforward introduction to chemical applications of the catastrophe theory. It is primarily intended for chemists interested in placing chemical reactions in the broader context of non-linear science, but it has a practical relevance for scientists in general. Catastrophe theory deals with those non-linear phenomena in which a continuous change in the control parameters results in a discontinuous alteration of a characteristic quantity of the system. The author discusses the origins of catastrophe theory, giving examples of occurrences in the areas of physics, chemistry and biology. Elementary theory and non-chemical applications are also described. The chemical kinetics and methods of analysis of chemical kinetic equations arising from elementary and generalized catastrophe theories are reviewed. Finally, the theory is applied to analyse and classify phenomena associated with the stability loss that may occur in chemical reactions. The book contains over 100 figures and an extensive subject index.

  • Angle-Resolved Photoemission

    Theory and Current Applications
    • 1 Edición
    • Volumen 74
    • S.D. Kevan
    • Inglés
    Angle-resolved photoemission has become an indispensable tool for solid state and surface physicists and chemists. This book covers the underlying phenomenology of the technique, reviews its application to existing problems, and discusses future applications. The book is particularly timely given the significant improvements in experimental and theoretical methodology which have recently been or soon will be attained, namely, ultrahigh resolution studies using improved sources of synchrotron radiation, quasiparticle interpretation of measured dispersion relations and spectra, in situ growth of novel materials, etc. The technique has been applied predominantly to understand materials for which the one-electron paradigm is a reasonable approximation. Most chapters discuss this type of experiment: 2D and 3D states in metals and semiconductors, extrinsic states induced by adsorption, etc. Applications of the technique to materials where electron correlation plays a comparable role to that of solid state hybridization, ferro- and antiferromagnets, high Tc superconductors, etc. are rapidly growing in popularity. These areas are also discussed and a foundation is laid for further experiments in this direction.Almost all chapters contain comprehensive bibliographies and compendia of systems studied. The book has an extensive index which cross references applications and systems studied.

  • Combining C-C ?-Bonds

    Volume 5
    • 1 Edición
    • L.A. Paquette
    • Inglés
    The guiding principle underlying the subject matter specifically compiled in Volume 5 has been to make available to the organic chemical community a sourcebook comprehensively covering all the important &pgr;-bond-depen... transformations. Thermal, photochemical, and metal-catalyzed cycloadditions of every major type are expertly detailed by the most knowledgeable researchers in these areas. The synthetically useful electrocyclic and sigmatropic processes where alkenic centers are intimately involved in the structural change are similarly canvassed in compact detail. With added attention given to ene reactions, small-ring rearrangements, and related transition metal-associated reactions, coverage has been achieved of the full range of organic transformations directly involving the rebonding of alkenic centers. As a consequence, this volume should serve as the comprehensive sourcebook of the field for the next decade and beyond.

    • Inglés
    Nowadays, there are increasing demands for the control and specification of all aspects of industrial manufacturing. There is also a growing need to understand various biological processes and conditions for agricultural production, and concern for protection of the environment and human health. These factors have made it imperative to develop adequate methods for the analysis of gaseous substances or substances that can be converted to the gaseous state. It is not only necessary to apply known and developed methods correctly, but novel analytical procedures must also be found. Instrumentation should be improved and the applications of these methods will have to be extended. The present volume provides a comprehensive description of the state-of-the-art and of future possibilities in the analysis of gaseous substances. In the individual chapters the following themes have been discussed; the theoretical basis for the methods, a description of the instrumentation and the steps necessary in actual analyses and an outline of the principal areas in which each method can be employed. Both classical methods that are still useful for the solution of analytical problems using simple instrumentation, and the newest methods in the field are described. Special attention is paid to modern electrochemical and spectroscopic methods, and to methods based on a number of physical principles. Gas chromatography is discussed in the greatest detail because of its specially important position in modern analytical chemistry.The book should be well received by the analytical public and should be extremely useful to students and workers in scientific research laboratories and in fields dealing with environmental protection.

  • Chemistry of the Platinum Group Metals

    Recent Developments
    • 1 Edición
    • Volumen 11
    • F.R. Hartley
    • Inglés
    The chemistry of platinum group metals is a rapidly expanding commercially important field. It is dominated by the catalytic properties of the metals. They are useful in petrochemical and general chemical plants and are becoming increasingly important as autocatalysts for pollution control. The book covers recent developments in the chemistry of the six platinum group metals, namely, platinum, palladium, rhodium, iridium, ruthenium and osmium. The material falls into three broad areas. Firstly, the occurrence, extraction and use of the metals, especially in catalysis, electrochemistry, energy and electronics. Secondly, organometallic and homogeneous catalytic chemistry and last but not least coordination chemistry including biochemistry and cancer therapy. The work is aimed at scientists in universities and in industry using any of the six platinum group metals in research. It will be useful for those studying the compounds of the metals themselves, and those considering to use either the metals or their complexes and catalysts in their experimental work.

  • Stationary Phases in Gas Chromatography

    • 1 Edición
    • Volumen 48
    • H. Rotzsche
    • Inglés
    The primary aim of this volume is to make the chemist familiar with the numerous stationary phases and column types, with their advantages and disadvantages, to help in the selection of the most suitable phase for the type of analytes under study. The book also provides detailed information on the chemical structure, physico-chemical behaviour, experimental applicability, physical data of liquid and solid stationary phases and solid supports. Such data were previously scattered throughout the literature. To understand the processes occurring in the separation column and to offer a manual both to the beginner and to the experienced chromatographer, one chapter is devoted to the basic theoretical aspects. Further, as the effectiveness of the stationary phase can only be considered in relation to the column type, a chapter on different column types and the arrangement of the stationary phase within the column is included.The secondary aim of this book is to stimulate the development of new and improved standardized stationary phases and columns, in order to improve the reproducibility of separations, as well as the range of applications.

  • New Trends in CO Activation

    • 1 Edición
    • Volumen 64
    • L. Guczi
    • Inglés
    The aim of this volume is to provide scientists with a comprehensive summary of new research areas in the activation of carbon monoxide, as one of the most reactive molecules, and in its applications. In order to understand the variety of the reactivity of CO, a quantum-chemical approach helps the reader to understand the binding state of CO to the solid surface (Chapter 1). The structure of the adsorbed CO can be better understood by examining its reactivity towards single crystals in the absence and in the presence of promoters (Chapter 2). The first approach in the reactivity study is that of studying catalytic activity of single crystals and structure sensitivity which are summarized in Chapter 3. One of the most prominent effects in the CO activation process is ascribed to the presence of additives, promoters which, in a real catalyst system, are far more complicated than on single crystal surfaces (Chapter 4). The original Fischer-Tropsch process applied fused iron or cobalt catalysts which were suitable for producing mainly straight chain hydrocarbons. The two most important processes involving CO activation, the new FT process and alcohol formation are discussed in Chapters 5 and 7. An important type of catalyst, the bimetallic catalysts, is discussed in Chapter 6. The role of hydrogen as one of the most frequently used partners in CO activation is discussed in Chapter 8. The field of production of specialty chemicals is an excellent example of the homogeneous catalytic activation of CO (Chapter 9). In Chapter 10 an overview is given of the industrial applications of CO chemistry and these are illustrated by working processes. The final chapter gives the reader some hints about future progress in the field.

    • Inglés
    The organizers of this Fifth Symposium maintained their initial objectives, namely to gather experts from both industries and universities to discuss the scientific problems involved in the preparation of heterogeneous catalysts, and to encourage as much as possible the presentation of research work on catalysts of real industrial significance. Another highlight of these symposia was to reserve a substantial part of the program to new developments in catalyst preparation, new preparation methods and new catalytic systems. The fact that chemical reactions which were hardly conceivable some years ago have become possible today through the development of appropriate catalytic systems proves that catalysis is in constant progress.The papers in this volume deal with studies of unit operations in catalyst preparation, catalyst preparation via the sol-gel route, preparation of catalysts from layered structures and pillaring of clays, preparation and modification of zeolite-based catalysts, carbon supported catalysts, preparation of oxidation catalysts and novel and unusual preparation methods.

    • Abraham Ulman
    • Inglés
    The development of oriented organic monomolecular layers by the Langmuir-Blodgett (LB) and self-assembly (SA) techniques has led researchers toward their goal of assembling individual molecules into highly ordered architectures. Thus the continually growing contribution of LB and SA systems to the chemistry and physics of thin organic films is widely recognized. Equally well-known is the difficulty in keeping up to date with the burgeoning multidisciplinary research in this area. Dr. Ulman provides a massive survey of the available literature. The book begins with a section on analytical tools to broaden the understanding of the structure and properties of monolayers and films. Following sections discuss LB films, the preparation and properties of SA monolayers and films, the modeling of LB and SA monolayers, and the application of LB and SA films.

    This book has been written by a group of mathematicians and chemists whose common interest is in the complex dynamics of catalytic reactions. Based on developments in mathematical chemistry, a general theory is described that allows the investigation of the relationships between the kinetic characteristics of complex reactions and their detailed reaction mechanism. Furthermore, a comprehensive analysis is made of some typical mechanism of catalytic reactions, in particular for the oxidation of carbon monoxide on platinum metals. In fact, the book presents three kinetics: (a) detailed, oriented to the elucidation of a detailed reaction mechanism according to its kinetic laws; (b) applied, with the aim of obtaining kinetic relationships for the further design of chemical reactors; and (c) mathematical kinetics whose purpose is the analysis of mathematical models for heterogeneous catalytic reactions taking place under steady- or unsteady-state conditions.
