Synopsis Extractive Metallurgy of Activated Minerals by : P. Baláž
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.

Synopsis Mechanochemistry in Nanoscience and Minerals Engineering by : Peter Balaz
Mechanochemistry as a branch of solid state chemistry enquires into processes which proceed in solids due to the application of mechanical energy. This provides a thorough, up to date overview of mechanochemistry of solids and minerals. Applications of mechanochemistry in nanoscience with special impact on nanogeoscience are described. Selected advanced identification methods, most frequently applied in nanoscience, are described as well as the advantage of mechanochemical approach in minerals engineering. Examples of industrial applications are given. Mechanochemical technology is being applied in many industrial fields: powder metallurgy (synthesis of nanometals, alloys and nanocompounds), building industry (activation of cements), chemical industry (solid waste treatment, catalyst synthesis, coal ashes utilization), minerals engineering (ore enrichment, enhancement of processes of extractive metallurgy), agriculture industry (solubility increase of fertilizers), and pharmaceutical industry (improvement of solubility and bioavailability of drugs). This reference serves as an introduction to newcomers to mechanochemistry, and encourages more experienced researchers to broaden their knowledge and discover novel applications in the field.

Synopsis Mechanochemistry of Materials by : E. M. Gutman
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

Synopsis Shape-Memory Polymer Device Design by : David L. Safranski
Shape-Memory Polymer Device Design discusses the latest shape-memory polymers and the ways they have started to transition out of the academic laboratory and into devices and commercial products. Safranski introduces the properties of shape-memory polymers and presents design principles for designing and manufacturing, providing a guide for the R&D engineer/scientist and design engineer to add the shape memory effect of polymers into their design toolbox. This is the first book to focus on applying basic science knowledge to design practical devices, introducing the concept of shape-memory polymers, the history of their use, and the range of current applications. It details the specific design principles for working with shape-memory polymers that don't often apply to mechanically inactive materials and products. Material selection is thoroughly discussed because chemical structure and thermo-mechanical properties are intrinsically linked to shape-memory performance. Further chapters discuss programming the temporary shape and recovery through a variety of activation methods with real world examples. Finally, current devices across a variety of markets are highlighted to show the breadth of possible applications. - Demystifies shape-memory polymers, providing a guide to their properties and design principles - Explores a range of current and emerging applications across sectors, including biomedical, aerospace/automotive, and consumer goods - Places shape-memory polymers in the design toolkit of R&D scientists/engineers and design engineers - Discusses material selection in-depth because chemical structure and thermo-mechanical properties are intrinsically linked to shape-memory performance

Synopsis Catalysis by : James J Spivey
This volume looks at modern approaches to catalysis and reviews the extensive literature. Chapters highlight application of 2D materials in biomass conversion catalysis, plasmonic photocatalysis, catalytic demonstration of mesoporosity in the hierarchical zeolite and the effect of surface phase oxides on supported metals and catalysis. Looking to the future a chapter on ab initio machine learning for accelerating catalytic materials discovery is included. Appealing broadly to researchers in academia and industry, these illustrative chapters bridge the gap from academic studies in the laboratory to practical applications in industry not only for catalysis field but also for environmental protection. Other chapters with an industrial perspective include heterogeneous and homogeneous catalytic routes for vinyl acetate synthesis, catalysis for production of jet fuel from renewable sources by HDO/HDC and microwave-assisted catalysis for fuel conversion. Chemical reactions in ball mills is also explored. The book will be of great benefit to any researcher wanting a succinct reference on developments in this area now and looking to the future.
