Описание: For rather a long time numerical results in chemical kinetics could only be obtained for very simple chemical reactions, most of which were of minor practi ca 1 importance. The avail abil ity of fast computers has provi ded new opportunities for developments in chemical kinetics. Chemical systems of practical interest are usually very complicated. They consi st of a great number of different el ementary chemi cal reacti ons, mostly with rate constants differi ng by many orders of magni tude, frequently with surface reacti on steps and often wi th transport processes. The deri vati on of a 'true' chemical mechani sm can be extremely cumbersome. Mostly this work is done by setting up 'reaction models' which are im- proved step by step in comparison with precise experimental data. At this early stage mathematics is involved, which may al ready be rather complicated. Mathematical methods such as pertubation theory, graph theory, sensitivity analysis or numerical integration are necessary for the derivation and application of optimal chemical reaction models. Most theoretical work aimed at improving the mathematical methods was done on chemical reactions which mostly were of little practical im- portance. Chemi cal engi neers, who evi dently k now well how important the chemical model s and their dynamics are for reactor desi gn, have al so to be convinced not only on the theoretical work but also on its practical applic- abil ity.

The major goals of quantum chemistry include increasing the accuracy of the results for small molecular systems and increasing the size of large molecules that can be processed, which is limited by scaling considerations--the computation time increases as a power of the number of atoms. This book offers scope for academics, researchers, and engineering professionals to present their research and development works that have potential for applications in several disciplines of computational chemistry. Contributions range from new methods to novel applications of existing methods to gain an understanding of the concepts.

Physical-Chemical Mechanics of Disperse Systems and Materials is a novel interdisciplinary area in the science of the disperse state of matter. It covers the broad spectrum of objects and systems with dimensions ranging from nanometers to millimeters and establishes a fundamental basis for controlling and tuning the properties of these systems as well as the processes taking place in them.
Physical-chemical mechanics focuses on the analysis of the complex physical-chemical interfacial phenomena taking place both in the transition of a dispersed system into a material, such as in the course of pressing, sintering, hydration hardening, and sol-gel transitions, and in the course of the dispersion of bulk materials taking place in milling, mechanical treatment, friction and wear, and fracturing. These studies are based on thorough experimental investigation of contact interactions between particles in these processes.
The book is divided into two sections. The first section covers basic principles of the formation, stability and rupture of contacts between particles in different media and in surfactant solutions, as well as the properties of coagulation structures and their rheology. The second section covers surface phenomena taking place in solid-like structures with phase contacts and in compact bodies with an emphasis on several applications and processes as well as the special role of the Rehbinder effect.
Where appropriate and relevant, the book presents essays on specific significant and principal studies, such as the damageability of crystal and glass surfaces, the strength of industrial catalysts, the nano-mechanisms of cement hardening, the role of the structure-mechanical barrier in the stabilization of fluorinated systems, and contact interactions in papermaking. It also devotes attention to experimental methods used in physical-chemical mechanics, the direct measurement of contact strength, and relevant instrumentations.
The book utilizes the content used over many years in lecture courses and includes fundamental material on colloid and surface chemistry, the strength of materials, rheology, and tensors, which makes it well suited for novices and experts in the field.
