Colloid and Interface Science, Volume IV: Hydrosols and Rheology is the fourth volume of papers presented at the International Conference on Colloids and Surfaces, held in San Juan, Puerto Rico on June 21-25, 1976. This volume contains 57 chapters and begins with reviews on colloidal dispersions, interacting latex particles, reversible adsorption of hydrosols, and stability of colloidal kaolinite suspensions. The next chapters deal with determination of colloidal stability, the microstructure of latex particles, instrumentation, and analytical methods for rheology measurement. These topics are followed by discussions of polymer adsorption, kinetic aspects of rheology, and measurement of important parameters in adsorption. This text also explores the properties of surface rheological models, the analysis of sedimentation velocity, and the application of hydrodynamic chromatography. The remaining chapters look into the colloid chemical aspects of drilling fluid rheology, the rheology of dilute polymer solutions, colloidal sol flow, and the shear thickening of colloidal dispersions, This book will prove useful to chemical engineers and other related professions who are interested in colloidal dispersion, rheology, and hydrosols.

Clay Science in Drilling and Drilling Fluids starts from the fundamentals of clay science and drilling, then comprehensively presents the advances of clay science related to drilling and drilling fluids and ends with discussion of industrial clay products. The topics combine to present the whole picture of fundamental research and industrial applications of clays and clay minerals in drilling operations, which is of general interest to researchers and engineers working in the related fields.Oil and gas are the primary sources of energy in human society and the foundation of the petrochemical industry. However, extracting these resources present a number of drilling challenges, including high temperature and high pressure (HTHP), offshore drilling, high angle drilling, and even horizontal drilling, among others. As a result, it is crucial to develop advanced drilling and drilling fluid technologies. Clay science in drilling and drilling fluids should be clarified for this purpose because clays and clay minerals are one of the most important components of drilling fluids and have a significant impact on wellbore stability. Clay Science in Drilling and Drilling Fluids covers the different levels of clay science in drilling and drilling fluids, i.e., form fundamentals, the latest research results, applications, and commercial products. - Covers the fundamentals of clay minerals, drilling, and drilling operations - Discusses applications of the research and science to real world problems - Introduces available commercial clay products and recommends their use for specific situations

This volume is organized into 51 chapters that cover the subjects of biocolloids, polymers, monolayers, membranes, and general papers. Other topics discussed include the thermodynamic aspects of biocolloids; adsorption of polymers; ion-exchange behavior; optical properties of polymers; microvoid films; micellar systems; and liquid crystals. The remaining chapters explore the diffusion and sorption of simple ions, surface properties of copolymers, and adhesion of thermoplastic elastomers.

The process of froth flotation is an outstanding example of applied surface chemistry. It is extensively used in the mining, mineral, metallurgical, and chemical industries for separation and selective concentration of individual minerals and other solids. Substances so concentrated serve as raw materials for producing appropriate metals and chemicals. The importance of flotation in technology is chiefly due to the ease with which it can be made selective and versatile and to the economy of the process. The objective of this book is to review the fundamentals of surface chemistry together with the relevant aspects of organic and inorganic chemistry that-in the opinion of the author-are important ~ control of the froth flotation process. The review updates the information that had been available in books by Sutherland and Wark (1955), Gaudin (1957), Klassen and Mokrousov (1963), and GIembotsky et al. (1963). It emphasizes mainly the surface chemical aspects of the process, leaving other relevant topics such as hydrodynamics, mechanical and electrical technology, cir cuit design and engineering, operations research, instrumentation tech nology, modeling, etc., to appropriate specialized treatments.

Polymerie materials have been replacing other conventional materials like metals, glass and wood in a number of applications. The use of various types of fillers incorporated into the polymer has become quite common as a means of reducing cost and to impart certain desirable mechanieal, thermal, electrieal and magnetic properties to the polymers. Oue to the energy crisis and high priees of petrochemieals, there has been a greater demand to use more and more fillers to cheapen the polymerie materials while maintaining and/or improving their properties. The advantages that filled polymer systems have to offer are normally offset to some extent by the increased complexity in the rheological behavior that is introduced by the inclusion of the fillers. Usually when the use of fillers is considered, a compromise has to be made between the improved mechanieal properties in the solid state, the increased difficulty in melt processing, the problem of achieving uniform dispersion of the filler in the polymer matrix and the economics of the process due to the added step of compounding. It has been recognized that addition of filler to the polymer brings a change in processing behavior. The presence of the filler increases the melt viscosity leading to increases in the pressure drop across the die but gives rise to less die swell due to decreased melt elasticity.

Ever since the first volume appeared in 1969, this series has received good reviews in a variety of periodicals published in different corners of the world. It would seem that the work has fulfilled its purpose as outlined in the Preface to Volume 1. The rapidly increasing interest in surface and colloid science by people engaged in industrial research and development, and in environmental, ecological, medical, pharmaceutical, and other areas, justifies the continuation of such an effort. The Surface and Colloid Science series originated with John Wiley and Sons and has been continued with Plenum Press. This volume is the third with the present publisher, and is the best assurance of our mutual interest to proceed with this work. Some books in the series, as was the case with Volume 11, may appear under the editorship of other workers in the field. For reasons of continuity, a sequential numbering system will be maintained. This editor hopes to provide the scientific and technical community with high-quality contributions in surface and colloid science in the future. He invites specialists to submit definitive chapters on any topic within the broad area of our discipline for inclusion in this series.
