Book Description
Organic Mechanochemistry and Its Practical Applications gathers physical and organic chemistry-based molecular principles, evolving interpretations of scientific data, and real world applications to demonstrate the synthetic advantages of mechanically initiated organic reactions. This book considers transformations of organic substances upon mechanical actions and explains how mechanical energy is transformed into chemical driving force. The author, a renowned expert in physical and organic chemistry, carefully examines the concurrent chemical and physical processes—particularly polymerization and dynamic shearing—that involve organic substances and inorganic surfaces during lubrication. Dr. Todres discusses the various factors that affect boundary lubrication, such as material properties, chemical reactivity, pressure, and temperature. The book describes conformational transformations and structural phase transitions of organic molecules and working materials that take place under mechanical forces, such as drilling, grinding, friction, and shearing, and shock-waves. Other key topics include mechanochromism, tribopolymerization, mechanical activation of organic reactions, and the peculiarities of catalytic effects in organic mechanochemistry. Throughout the text, the author highlights novel technical applications of mechanochemical phenomena in a variety of fields, including lubrication, biomedical engineering, pharmaceutical drug formulation, environmental protection, and practical economy. Organic Mechanochemistry and Its Practical Applications reveals how mechanochemistry was inspired by principles in various disciplines to create innovative approaches for current challenges in these fields.

Book Description
Mechanochemical Organic Synthesis is a comprehensive reference that not only synthesizes the current literature but also offers practical protocols that industrial and academic scientists can immediately put to use in their daily work. Increasing interest in green chemistry has led to the development of numerous environmentally-friendly methodologies for the synthesis of organic molecules of interest. Amongst the green methodologies drawing attention, mechanochemistry is emerging as a promising method to circumvent the use of toxic solvents and reagents as well as to increase energy efficiency. The development of synthetic strategies that require less, or the minimal, amount of energy to carry out a specific reaction with optimum productivity is of vital importance for large-scale industrial production. Experimental procedures at room temperature are the mildest reaction conditions (essentially required for many temperature-sensitive organic substrates as a key step in multi-step sequence reactions) and are the core of mechanochemical organic synthesis. This green synthetic method is now emerging in a very progressive manner and until now, there is no book that reviews the recent developments in this area. - Features cutting-edge research in the field of mechanochemical organic synthesis for more sustainable reactions - Integrates advances in green chemistry research into industrial applications and process development - Focuses on designing techniques in organic synthesis directed toward mild reaction conditions - Includes global coverage of mechanochemical synthetic protocols for the generation of organic compounds

Book Description
This book focuses on the triboemission of low-energy electrons from the freshly generated surface. These electrons play the most crucial role in the chemical reactions at the tribological interface. New models and TIP (thermodymanics of irreversible processes) describe in detail the behavior of emitted electrons which lower the activation energy of the chemical reactions. This book also highlights tribocatalysis phenomena as examples of the lowering of the activation energy. A book titled Tribocatalysis has never been published before this.

Book Description
The main goal in preparing this book was to publish contemporary concepts, new discoveries and innovative ideas in the field of surface engineering, predominantly for the technical applications, as well as in the field of production engineering and to stress some problems connected with the use of various surface processes in modern manufacturing of different purpose machine parts. This book is an attempt to introduce science into the study of surface treatment processes. Tribology offers a good approach for describing abrasive machining and coating processes and offers the ability to predict some of the outputs of the processes. The study of friction, forces, and energy explores the importance of the various factors which govern the stresses and deformations of abrasion. The effects of grain shape, depth of penetration, and lubrication on the process forces are explored. The tribology of nanostructured surfaces involves many fundamental and scientific issues. More importantly, it has tremendous applications in industries. It is a powerful tool to regulate friction, adhesion, and wetting of surfaces by altering their geometric textures and material compositions at the nanoscale, and, hence, to control the tribological performance of the engineering surfaces.

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.

Book Description
Chromic or colour related phenomena are produced in response to a chemical or physical stimulus. This new edition will update the information on all those areas where chemicals or materials interact with light to produce colour, a colour change, or luminescence especially in the imaging, analysis, lighting and display areas. The book has been restructured to show greater emphasis on applications where 'coloured' compounds are used to transfer energy or manipulate light in some way therefore reducing the details on classical dyes and pigments. In the past eight years, since the previous edition, there has been a remarkable increase in the number of papers and reviews being produced reflecting the growth of interest in this area. This ongoing research interest is matched by a large number of new technological applications gaining commercial value covering e.g. biomedical areas, energy, data storage, physical colour, bio-inspired materials and photonics. This book appeals to industrial chemists, professionals, postgraduates and as high level recommended reading for colour technology courses.

Book Description
Providing in-depth information on how to obtain high-performance materials by controlling their nanostructures, this ready reference covers both the bottom-up and the top-down approaches to the synthesis and processing of nanostructured materials. The focus is on advanced methods of mechanical nanostructuring such as severe plastic deformation, including high pressure torsion, equal channel angular processing, cyclic extrusion compression, accumulative roll bonding, and surface mechanical attrition treatment. As such, the contents are inherently application-oriented, with the methods presented able to be easily integrated into existing production processes. In addition, the structure-property relationships and ways of influencing the nanostructure in order to exhibit a desired functionality are reviewed in detail. The whole is rounded off by a look at future directions, followed by an overview of applications in various fields of structural and mechanical engineering. With its solutions for successful processing of complex-shaped workpieces and large-scale specimens with desired properties, this is an indispensable tool for purposeful materials design.
