Each of the many different varieties of silica is characterised by its crystalline or amorphous structure and its specific physico-chemical surface properties. It is these surface characteristics which determine the applications of the silica, be it for chromatography, dehydration, polymer reinforcement or other processes. All the recent advances in the use of established and more modern methods for the determination of the surface and morphological characteristics of silicas, are found in this book written by a team of European experts. Analytical methods discussed include: solid state nuclear magnetic resonance, infra-red spectroscopy and adsorption methods. Emphasis is given to the nature and distribution of hydroxyl groups on silica surfaces; the final chapter gives a general survey of the health and safety aspects of silica.

Surfactants and Interfacial Phenomena Milton J. Rosen Bridging the gap between purely theoretical aspects of surface chemistry and the purely empirical experience of the industrial technologist, this book applies theoretical surface chemistry to understanding the action of surfactants in modifying interfacial phenomena. It surveys the structural types of commercially available surfactants and discusses interfacial phenomena, the physicochemical principles underlying the action of surfactants in each phenomenon, and the effect of structural changes in the surfactants and environmental changes on their action. Tables of data on various interfacial properties of surfactants, compiled and calculated from the latest scientific literature, are included. 1978 304 pp. An Introduction to Clay Colloid Chemistry, 2nd Ed. H. van Olphen This book provides valuable guidance in research and design efforts by giving a clear understanding of principles and concepts of colloid chemistry as applied to clay systems. Updated and enlarged, this edition includes new information on surface characterization and adsorption mechanisms; recent results in the area of clay-organic interaction--the intercalation and intersalation of kaolinite minerals; and increased attention to the possible role of clays in biological evolution. 1977 318 pp. Physicochemical Processes for Water Quality Control Walter J. Weber, Jr. Focusing on physicochemical rather than biological processes, this book presents a comprehensive treatise on the treatment of municipal and industrial water and wastewater. All of the physicochemical processes important to municipal and industrial water and wastewater treatment--coagulation, filtration, membrane processes, chemical oxidation, and others--are included and each is covered thoroughly from principle through application. To maintain a high level of expertise, contributions have been incorporated from specialists actively involved in research or engineering applications in each area considered. 1972 640 pp.

The strength of silica gel lubricants prepared with highly purified oils thickened by hydrophobic and nonhydrophobic silica gel is reduced with an increase in temperature. For the same type of lubricants based on nonhydrophobic SiO2 the change in strength with an increase in the oleic acid concentration has an extremal character with maxima at an oleic acid concentration of 0.5%. The addition of oleic acid lubricants based on hydrophobic silica gel leads to a reduction in the lubricant strength at all temperatures except 120C. At this temperature an extremal dependence with a maximum at an oleic acid concentration of 0.1% is observed. The temperature dependence of the lubricant strength carries an extremal character with a maximum at temperatures ranging from 50 to 120C for lubricants based on low-purity oils, and also for lubricants based on highly purified oils with additions of oleic acid.

This book explores the improvement in thermal insulation properties of protein-based silica aerogel composites fabricated by a novel, inexpensive and feasible method. The resulting material exhibits polymeric foam behavior including high compressibility, super-hydrophobic qualities and excellent strain recovery in addition to low thermal conductivity. The fabrication methodologies are explained in great detail and represented in flowcharts for easy reference and understanding. This monograph gives readers a new perspective on composite fabrication using methods other than the traditional ones and explores the endless ways of altering the composition to modify the properties of the silica aerogel composites. Applications for this novel composite are diverse and range from those in the pharmaceutical and aerospace industries to the oil and gas industries.
