Hardcover. Condizione: new. Hardcover. Deep and detailed discussions on chemistry, chemical physics, photoelectrochemistry, photophysics, photocatalysis and possible applications of nanostructured semiconductor materials have shown increasing interest in the matter by scientists representing various research areas as well as industrial enterprises. Indeed, solar energy conversion and chemical methods for its realization became very popular again after the great jump of renewable energy sources between the middle of the 1970s and the beginning of the 1980s. Several excellent books have been published over the past years, however, in these books no attempt was made to approach this research area from the point of view of classical chemical physics. With this book, the editors aim: a) to generate an adequate scope of the modern trends and data obtained during the last years in the area of chemical physics of nanostructured materials, in particular, nanocrystalline semiconductors; b) to select an equal mix of scientists from Western and Eastern countries, all of them experts in their respective research areas; and c) to present to the international scientific community many interesting and important results which have been obtained by former Soviet Union researchers, but are not well known because they had originally been published in Russian books and journals. This book will be interesting and useful for scientists working in the area of semiconductor nanotechnology, photoelectrochemistry, photocatalysis, photochemistry of water and air purification, as well as for graduate and post-graduate students who are planning to join these research areas.

Hardcover. Condizione: new. Hardcover. The monograph is intended to systematize data on active sites and their kinetic and stereospecific heterogeneity (polysite phenomenon) in olefin and diene monomer ion, ion-coordination and complex radical polymerization processes. Questions of molecular-mass distribution of polymers obtained by ion and ion-coordination polymerization methods are discussed together with composition and stereo regularity distribution of olefin copolymers. Data on the influence of transition and non-transition metal origin and their ligand ambience, conditions of catalytic system preparation and polymerization are shown. Various assessment methods of polymerization active site distribution by kinetic activity and stereospecific action are considered. In particular, an assessment method for kinetic activity distribution at ion-coordination diene polymerization is described, mathematical simulation parameters for polymerization processes are shown, taking into account the polysite structure of catalytic systems. Of special attention are geometrical and electron structure of active sites in the ion-coordination polymerization by the quantum chemistry method, interrelation between reactivity of some types of active sites and stereospecificity of their action in diene polymerization. The importance of ratio between specific time elementary act duration at the diene injection, coordinated on an active site, and time of propagating macrochain end unit existence in the s-state at polydiene microstructure formation is indicated. Questions of the polysite mechanism occurrence in complex radical polymerization processes are discussed. A possibility for polymerization to proceed in both free-radical and complex related chain propagation sites is shown. Data on polysite phenomenon (distribution of active sites by kinetic activity and stereospecificity of action) in polymerization are analyzed. The examples of polysite phenomenon manifestation and assessment, and its connection with ion, ion-coordination and radical polymerization conditions for olefins and dienes are shown. Geometrical and electron structure of active sites in ion-coordination polymerization of dienes is considered and the relation between the structure, reactivity and stereospecificity of action of different site types is shown.

Hardcover. Condizione: new. Hardcover. The behavior of substances in solutions may not be adequately characterized by the effect of any single physicochemical parameter of solvents, nor are numerous semi-empirical scales of the solvent effect (their polarity ) suitable for their limited selections only. In recent decades, it has been found that the variation of reaction rate constants in solutions or that spectral parameters of dissolved substances are determined by the total effect of different solvation processes. This monograph presents numerous examples of such an approach and characterizes various empirical and semi-empirical scales of solvent properties. It is shown that additional consideration of some structural parameters of solvents, namely, their cohesive energy and the molar volume, may provide for spreading this approach on homolytical and catalytic reaction. It is also shown that for the solvolysis reaction, one of the excessive reagents may represent either a reagent or a solvent, which requires additional consideration of its structural characteristics in the Hammeth equation. The application of the principle of free energy linearity also allowed adequate generalization of data on the effect of solvents on different physicochemical processes, such as dissolution of gases and solids in various solvents, swelling of polymers and solid fossil fuels, coal extraction, adsorption, absorption, diffusion, and chromatography. Special attention is paid to substance distribution between two immiscible phases. Properties of both an extractive phase and an active extractant dissolved in inert diluter are taken into account. The majority of these processes indicate the efficiency of solvent self-association factor that defines the energy consumption for formation of a void for an alien molecule injection.

NCPM is depicted in terms of a supramolecular (carcass-micellar) model. The model is thought to reflect heterophase packing of polymeric chains, which co-operate as a molecular-chain sponge. The NCPM model presented is proved for adequate description of principal structure-physical phenomena to elaborate the scheme of structural-kinetic modeling of chemical reactions in bulky polymers. Structure-physical phenomena elucidated in the monograph are: - peculiarities of polymer plasticization and polymer blending with liquids; - structural and thermodynamic aspects of sorption of low molecular species; - properties of ESR (spin) probes and optical (molecular) probes; - features of water absorbed by polymers; - mechanical and thermal effects generated by the molecular-chain sponge; - supramolecular aspects of NCPM chemical physics. This monograph includes the structural-kinetic modeling of complex polymer chemical reactions. It deals with the problem of mechanism and kinetics of free radical chain reactions using thermal and photochemical model reactions of dibenzoyl peroxide with glassy-like polymers (cellulose triacetate, polycarbonate, polystyrene, polyamide PA-548), viscoelastic polymers (atactic polypropylene, polyamide PA-548, polyethylene, polyisobutylene, melted poly(ethylene oxide), and isotactic polypropylene. In all cases, the supramolecular heterophase mechanism of the processes, which was unknown for homogeneous systems, was proved. Furthermore, heterophase mechanisms of photochemical reaction between naphthalene and cellulose triacetate and photolysis of poly(methyl methacrylate) proceeding as a photochain reaction are indicated.

Hardcover. Condizione: new. Hardcover. This volume documents the proceedings of the "International Symposium on Surface Contamination and Cleaning," held in Newark, New Jersey, May 23-25, 2001. Because of the importance of this topic in many technological areas, tremendous efforts have been devoted to devise novel and more efficient ways to monitor, analyse and characterize contamination on surfaces as well as ways to remove such contamination from a wide variety of surfaces. The technological areas where surface contamination has always been a bete noire and thus surface cleaning is of cardinal importance are too many and range from aerospace to microelectronics to biomedical. This volume contains a total of 24 papers, all rigorously peer reviewed and revised before inclusion, which deal with all kinds of contaminations on a host of surfaces. The topics covered include: mapping of surface contaminants; various techniques for cleaning surfaces; various techniques for monitoring level of cleanliness; acceptable cleanliness levels; ionic contamination; pharmaceutical cleaning validations; cleaning of glass surfaces; decontamination of sensitive equipment; no-chemistry process cleaning; waterjet cleaning; cleaning with solid carbon dioxide pellet blasting; cleanroom wipers; dust removal from solar panels and spacecraft on Mars; laser cleaning of silicon surfaces; particle removal; implications of surface contamination and cleaning; and future of industrial cleaning and related public policy-making.

Hardcover. Condizione: new. Hardcover. This volume documents the proceedings of the 8th International Symposium on Particles on Surfaces: Detection, Adhesion and Removal held in Providence, Rhode Island, June 24 26, 2002. The study of particles on surfaces is extremely crucial in a host of diverse technological areas, ranging from microelectronics to optics to biomedical. In a world of shrinking dimensions and with the tremendous interest in various nanotechnologies, the need to understand the physics of nanoparticles becomes quite patent. With the interest in and concern with nanoparticles comes the need for new and more sensitive metrological and analysis techniques to detect, quantitate, analyze and characterize very small particles on a host of substrates. This volume contains a total of 21 papers covering many ramifications of particles on surfaces. All manuscripts were rigorously peer-reviewed and all were revised and properly edited before inclusion in this volume. The book is divided into two parts: Particle Analysis/Characterization and General Cleaning-Related Topics and Particle Adhesion and Removal. The topics covered include: nature and characterization of small particles; surface and micro-analytical methods for particle identification; haze as a new method to monitor nano-sized particles; particle transport and adhesion in ion-beam sputter deposition process; particle deposition during immersion rinsing; ice-air blast cleaning; rectangular jets for surface decontamination; factors important in particle adhesion and removal; mechanics of nanoparticle adhesion; particle adhesion on nanoscale rough surfaces; various techniques for cleaning or removal of particles from different substrates including wet cleaning, use of modified SC-1 solutions, use of surfactants, ozonated DI water, ultrasonic, megasonic, laser, energetic clusters; and post-CMP cleaning. This volume, together with its predecessors, will be of immense value to anyone interested in the world of particles on surfaces, and will serve as a resource for information on contemporary R&D activity in this extremely technologically important area.
