Book Description
This work systematically develops an energetics-based approach to analyzing the processes by which defects are formed and to initiating various types of mechanochemical reactions. The areas reviewed by the author include the energy balance in mechanochemical processes, the nature and reactivity of structural defects and deformation mobility and solid-phase reactions.

Book Description
Considerable advances have been made in mechanochemistry in the last couple of decades. Training of experts in this field with a background in materials science, chemical and mechanical engineering, etc. requires study of the fundamentals of mechanochemistry. There is a need for a textbook in the general and compressed form which would cover many aspects and would be used as a basis for understanding the fundamental principles to control mechanochemical phenomena. This textbook is based on lectures given by Prof Gutman in a graduate course in the mechanochemistry of materials at the Ben-Gurion University of the Negev. The book contains examples of experimental results to illustrate the mechanochemical phenomena and technologies Contents What is mechanochemistry of materials? Basic features of the behaviour of solids relevant to mechanochemical processes Irreversible thermodynamics of mechano-chemical reactions Kinetics of mechanochemical reactions under different stress state Main types of heterogeneous mechano-chemical reactions Mechanoelectrical phenomena and mechano-emission Application of mechanochemistry in materials engineering

Book Description
This book covers the fundamental relationships between solid surface chemical reactivity and the stressed state of surface layers; developed mainly by the author. Acceleration of chemical reactions by mechanical action (mechanochemical effect) and near-surface plasticity increase caused by chemical reactions (chemomechanical effect) acting simultaneously; open new possibilities for the control of a wide range of processes from corrosion to new materials engineering.This monograph is a unique work on this subject and will be essential reading for undergraduate and postgraduate students engaged in studying surface phenomena in materials science; chemistry and chemical engineering; as well as for scientists and engineers in the industries where these phenomena are important.

Book Description
Mechanical activation of solids is a part of mechanochemistry, the science with a sound theoretical foundation exhibiting a wide range of potential application. Mechanical activation itself is an innovative procedure where an improvement in technological processes can be attained via a combination of new surface area and defects formation in minerals. Mechanical activation is of exceptional importance in extractive metallurgy and mineral processing and this area forms the topic of this book and is the result of more than twenty years of research and graduate teaching in the field. In pyrometallurgy, the mechanical activation of minerals makes it possible to reduce their decomposition temperatures or causes such a degree of disordering that the thermal activation may be omitted entirely. The potential mitigation of environmental pollutants is becoming increasingly important in this context. The lowering of reaction temperatures, the increase of the rate and amount of solubility, preparation of water soluble compounds, the necessity for simpler and less expensive reactors and shorter reaction times are some of the advantages of mechanical activation in hydrometallurgy. The environmental aspects of these processes are particularly attractive. Several industrial processes are examined and their flowsheets are presented as succesful of activation. In these processes, the introduction of a mechanical activation step into the technological cycle significantly modifies the subsequent steps. The book is designed for researchers, teachers, operators and students in the areas of extractive metallurgy, mineral processing, mineralogy, solid state chemistry and materials science.It will encourage newcomers to the mechanochemistry to do useful research and discover novel applications in this field.

Book Description
Mechanochemical processing is a novel and cost effective method of producing a wide range of nanopowders. It involves the use of a high energy ball mill to initiate chemical reactions and structural changes. High energy ball milling: Mechanochemical processing of nanopowders reviews the latest techniques in mechanochemistry and how they can be applied to the synthesis and processing of various high-tech materials.Part one discusses the basic science of mechanochemistry with chapters on such topics as the mechanism and kinetics of mechanochemical processes, kinetic behaviour in mechanochemically-induced structural and chemical transformations and materials design through mechanochemical processing. Part two reviews mechanochemical treatment of different materials including synthesis of complex ceramic oxides, production of intermetallic compound powders, synthesis of organic compounds, synthesis of metallic-ceramic composite powders and activation of covalent bond-based materials. Part three covers mechanochemical processes in metal powder systems and other applications with coverage of topics such as plating and surface modification using ultrasonic vibrations, activated powders as precursors for spark plasma sintering, titanium dioxide photocatalyst synthesis by mechanochemical doping and synthesis of materials for lithium-ion batteries.With its distinguished editor and international team of contributors, High energy ball milling: Mechanochemical processing of nanopowders is a standard reference for all those involved in the production of ceramic and metallic components using sintering and other powder metallurgy techniques to produce net shape components. Examines the latest techniques in mechanochemistry and how they can be applied to the synthesis and processing of various high-tech materials Discusses the basic science of mechanochemistry including kinetic behaviour, processes and mechanisms and materials design through mechanochemical processing Reviews mechanochemical treatment of different materials including synthesis of ceramic oxides, organic compounds and metallic-ceramic composite powders

Book Description
This text examines the formation, physical characteristics and chemical properties of 1,3-alkadienephosphonates with various structures. The special features of P-C bond-forming reactions and methods of forming conjugated multiple bond systems as applied in the synthesis of 1,3-alkadienephosphonates are discussed and the application of physical methods, especially 1H-, 13C- and 31P-NMR and X-ray crystallography, in determining the structures of organophosphorus compounds is demonstrated. The principal reactions of 1,3-alkadienephosphonates are presented.

Book Description
The series Topics in Current Chemistry presents critical reviews of the present and future trends in modern chemical research. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field. Review articles for the individual volumes are invited by the volume editors. Readership: research chemists at universities or in industry, graduate students.
