Proceedings of 1st International Conference on Mechanochemistry


Book Description

Mechanochemical transformations are the subject of increasing attention in solid state chemistry, physics and materials science as well as in development of advanced technologies. They have been discussed at a number of symposia on mechanochemistry and mechanical alloying in various countries. The International Mechanochemical Association organised the 1st International Conference on Mechanochemistry (InCoMe'93) held on March 23-26, 1993 in Kosice, Slovak Republic. More than 100 contributions from 17 countries were presented. The proceedings consist of two volumes: Vol 1 - Fundamentals and models of mechanically stimulated processes; Mechanically induced changes in the structure and properties; Vol 2 - Mechanochemical reactions and mechanical alloying; Technological aspects of ultrafine grinding and mechanical activation. The lectures included: Mechanochemical activation of solids (V V Boldyrev, Russia), Surface Mechanochemistry of Crystalline Solids (E Gutman, Israel), Mechanochemical Effects of Ultrasound (K S Suslick, USA), Mechanical Alloying in Materials Science (E Ivanov, USA), Mechanochemical Activation of Solid Particles Through Fine Grinding (I J Lin, Israe), Mechanical Activation of Solid Surfaces with Well Defined Stress Conditions (M Senna, Japan), Role of Mechanical Activation in Preparation of Catalysts (U Steinike, Germany), Nonequilibrium Phase Transformations of Intermetallic Compounds by Ball Milling (H Bakker, Holland), Correlations Between Energy Transfer and End Products in Mechanical Alloying (M Magini, Italy), Mechano-electrochemistry and Corrosion of Metals (V Gutman, Austria), Analogue Mathematical Description of Mechanical Activation (K Tkacova, Slovakia), Mechanism of Mechanochemical Synthesis in Oxide Systems (G R Karagedov, Russia), Mechanical Alloying of Iron and Boron Powders (V A Barinov, Russia), Effect of Mechanical Activation on Dissociation of Magnesite (V Jesenak, Slovakia), etc.







Mechanochemistry in Nanoscience and Minerals Engineering


Book Description

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.







Classical And Quantum Dynamics In Condensed Phase Simulations: Proceedings Of The International School Of Physics


Book Description

The school held at Villa Marigola, Lerici, Italy, in July 1997 was very much an educational experiment aimed not just at teaching a new generation of students the latest developments in computer simulation methods and theory, but also at bringing together researchers from the condensed matter computer simulation community, the biophysical chemistry community and the quantum dynamics community to confront the shared problem: the development of methods to treat the dynamics of quantum condensed phase systems.This volume collects the lectures delivered there. Due to the focus of the school, the contributions divide along natural lines into two broad groups: (1) the most sophisticated forms of the art of computer simulation, including biased phase space sampling schemes, methods which address the multiplicity of time scales in condensed phase problems, and static equilibrium methods for treating quantum systems; (2) the contributions on quantum dynamics, including methods for mixing quantum and classical dynamics in condensed phase simulations and methods capable of treating all degrees of freedom quantum-mechanically.
