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.

"Nanowerkstoffe für Einsteiger" hält, was der Titel verspricht: Eine leichtverständliche Einführung zu Nanowerkstoffen für alle, die sich mit den Grundlagen und dem Potential dieser vielseitigen Materialklasse vertraut machen möchten, ohne allzu tief in die physikalischen und chemischen Details einzusteigen. Nanowerkstoffe sind Materialien wie Metalle, Legierungen, Keramiken oder Polymere, in denen mindestens eine Längendimension kleiner als 100 Nanometer ist. In diesem Längenbereich zeigen diese Materialien ganz besondere und fein einstellbare optische, elektrische und mechanische Eigenschaften, die auf der makroskopischen Skala nicht zutage treten. Eine Vielzahl von Anwendungen an der Schnittstelle zwischen Materialwissenschaft, Chemie, Physik und Biologie ist bereits in kommerziell erhältliche Produkte umgesetzt worden. Jedes Kapitel beginnt mit einer Einführung in den Lernstoff "In diesem Kapitel" und endet mit einer Zusammenfassung "Wichtig zu wissen". In die Tiefe gehende Erklärungen sind in Boxen aufgenommen und können so leicht ausgelassen werden.

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.

Im ersten Teil des Buches werden die Tonminerale genau beschrieben und ihre Reaktionen (Ionenaustausch, Quellung, kolloidale Dispersionen, Wechselwirkung mit allen Arten organischer Verbindungen einschließlich von Polymeren) dargestellt. Der Hauptteil enthält das Verhalten der Tonminerale in Böden und die vielfältigen Einsatzmöglichkeiten in Geotechnik und allen möglichen Sparten der Industrie. In diesen Kapiteln finden sich auch Angaben zur Bindung von toxischen Stoffen und Pestiziden und die Verwendung als Abdichtungsmaterialien. Das Buch spricht den Wissenschaftler, Techniker und Ingenieur an, der in der Praxis mit Tonen arbeitet und deren Verwendungsmöglichkeiten prüft sowie den Studenten einschlägiger Fachrichtungen. Die praktische Verwendung der Tone und mögliche Einsatzgebiete sind schwerpunktmäßig behandelt.

This work focuses on complementary crystallographic and spectroscopic areas of dynamic structural science, from papers presented at the 46th NATO sponsored course in Erice, Sicily 2013. These papers cover a range of material from background concepts to more advanced material and represent a fully inter-disciplinary collection of the latest ideas and results within the field. They will appeal to practising or novice crystallographers, both chemical and biological, who wish to learn more about modern spectroscopic methods and convergent advances and hence vice versa for experimental and computational spectroscopists. The chapters refer to the latest techniques, software and results and each chapter is fully referenced. The volume provides an excellent starting point for new comers in the emerging, multi-disciplinary area of time resolved science.

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.
