    • M. Kucera
    • Inglés
    This volume presents an up-to-date survey of knowledge concerning addition type polymerizations. It contains nine chapters, each of which covers a particular basic term. Whenever necessary, the phenomena are discussed from the viewpoint of both stationary and non-stationary state of radical, ionic (i.e. anionic and cationic) and coordination polymerization. Special attention has been paid to the propagation process. It provides not only a general overview but also information on important special cases (theoretical conditions of propagation, influence of external factors, controlled propagation, copolymerization, mechanism of various propagation types, etc.). The book is arranged according to the basic steps in chain reactions, which is a novel approach in a monograph on this topic. It facilitates the identification of common features of various polymerization types which may appear quite different. This useful, comprehensive text should prove invaluable to all those involved in the field of macromolecular chemistry. It will also be of interest to all chemists who, beside the profound study of their own field, are looking for interdisciplinary liaison points.

    • 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.

  • 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.

  • Preparation of Catalysts V

    Scientific Bases for the Preparation of Heterogeneous Catalysts
    • 1 Edición
    • Volumen 63
    • B. Delmon + 3 más
    • 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.

    • 1 Edición
    • 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.

  • Kinetic Models of Catalytic Reactions

    • 1 Edición
    • Volumen 32
    • G.S. Yablonskii + 3 más
    • Inglés
    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.

    • Inglés
    Sol-Gel Science: The Physics and Chemistry of Sol-Gel Processing presents the physical and chemical principles of the sol-gel process. The book emphasizes the science behind sol-gel processing with a chapter devoted to applications. The first chapter introduces basic terminology, provides a brief historical sketch, and identifies some excellent texts for background reading. Chapters 2 and 3 discuss the mechanisms of hydrolysis and condensation for nonsilicate and silicate systems. Chapter 4 deals with stabilization and gelation of sols. Chapter 5 reviews theories of gelation and examines the predicted and observed changes in the properties of a sol in the vicinity of the gel point. Chapter 6 describes the changes in structure and properties that occur during aging of a gel in its pore liquor (or some other liquid). The discussion of drying is divided into two parts, with the theory concentrated in Chapter 7 and the phenomenology in Chapter 8. The structure of dried gels is explored in Chapter 9. Chapter 10 shows the possibility of using the gel as a substrate for chemical reactions or of modifying the bulk composition of the resulting ceramic by performing a surface reaction (such as nitridation) on the gel. Chapter 11 reviews the theory and practice of sintering, describing the mechanisms that govern densification of amorphous and crystalline materials, and showing the advantages of avoiding crystallization before sintering is complete. The properties of gel-derived and conventional ceramics are discussed in Chapter 12. The preparation of films is such an important aspect of sol-gel technology that the fundamentals of film formation are treated at length in Chapter 13. Films and other applications are briefly reviewed in Chapter 14. Materials scientists and researchers in the field of sol-gel processing will find the book invaluable.

    • Pier Giorgio Righetti
    • Inglés
    Immobilized pH gradients (IPG) represent the most advanced development of isoelectric focusing (IEF). Originally developed to overcome all the problems of IEF in soluble amphoteric buffers (CA) (such as pH gradient instability, complexation with CA chemicals, unreproducibility of pH gradients, protein precipitation at the pI), it turned out to be an entirely new technique, quite different in principle and operation from conventional IEF. The book is thus meant to bring the reader up to date with this fast developing field. The book is divided into six chapters containing information on: detailed treatment of all the chemistry of the Immobiline chemicals; theory of pH gradient generation (computer simulations, tables with all the possible pH recipes); all analytical aspects of IPGs, including staining techniques, blotting etc.; two-dimensional maps, with a detailed treatise of advantages and limitations; preparative aspects of IPGs, including comparison with other preparative electrophoretic techniques; some examples of applications, including genetic and forensic analysis, blood polymorphism etc.The book is extensive and up-to-date, while also extensively covering the theory. Clearly written, with easily accessible information, the volume is a worthy asset to the Lab. Techniques series.
