Micelles are prevalent in naturally occurring and biological catalytic reactions. However, it is only in recent decades that scientists have developed kinetic models clarifying how micelle-mediated catalysis works at a molecular level. Written by a leading expert in the field, Micellar Catalysis is an in-depth examination of how micelles affect reaction mechanisms and reaction rates in organic and inorganic reactions. The book first discusses the structural and chemical properties of micelles and the role of thermodynamics, concentration, and additives in forming micelles. Demonstrating how intermolecular forces influence the reaction mechanisms, the author presents kinetic models for reactions catalyzed by normal micelles, as well as mixed micelles and metallomicelles. The book also compares various types of catalytic reactions with and without micelles to quantify their effect on reaction rates and rate constants. Using this information, it illustrates how micelles can modify reaction rates and improve catalytic efficiency, particularly for industrial processes. The final chapter explains the principles of kinetics used for data analysis. Focused on kinetic, chemical, and physical aspects of micelle-mediated reactions, this book offers clear insight into the complex mechanisms that occur in biological reactions. Micellar Catalysis is an essential source of reference for scientists involved in the research and development of micelles for industrial and biochemical applications.

From Reports in Volume 5: "Recently polymer blends have emerged as one of the most important areas of research activity in the field of polymer science and technology. Because of their satisfactory performance in meeting specific needs of the polymer industry, they have drawn considerable attention in replacing not only many conventional materials, but also some of the polymers that are in vogue. By suitably varying the blend compositions and manipulating the processing conditions, tailor-made products with a unique set of end use properties can be achieved at a much lower cost and within a shorter time than would have been necessary for the development of a new polymer. The usefulness of such blends increases with the increasing range of applications of this type of materials." (Chapter 4) "New and growing demands on polymeric materials cannot be satisfied in future by an assortment extension of basic polymers. Although the introduction of new major-use basic polymer is possible, it seems unlikely in view of current projected economic and technical considerations. On the other hand, new products based on the modification of existing polymers have and will continue to be fruitful areas for both scientific and commercial developments. The driving forces for these developments are: 1. Improved performance, 2. Reduced cost, 3. Present, pending and future legislation dealing with health and environmental issues." (Chapter 11)

In the 20 years since the publication of the author's multi-contributor volume on defoaming, a vast amount of new work has been published and many new insights have been revealed. A cohesive, single-authored book, The Science of Defoaming: Theory, Experiment and Applications provides comprehensive coverage of the topic. It describes the mode of action of antifoams, presenting the relevant theory and the supporting experimental evidence. Beginning with an introductory chapter that discusses the intrinsic properties of foam, the book then describes experimental methods for measuring foam properties important for studying antifoam action and techniques used in establishing the mode of action of antifoams. Since most commercially effective antifoams are oil based, a chapter is devoted to the entry and spreading behavior of oils and the role of thin film forces in determining that behavior. The book reviews the mode of action of antifoams, including theories of antifoam mechanisms and the role of bridging foam films by particles and oil drops. It also addresses issues related to the effect of antifoam concentration on foam formation by air entrainment and the process of deactivation of mixed oil-particle antifoams during dispersal and foam generation. For applications where chemical antifoam use is unacceptable, the text examines mechanical means of defoaming, such as the use of rotary devices and ultrasound. The final chapters consider the application of defoaming in radically different contexts including waterborne latex paints and varnishes, machine washing of textiles, gas-oil separation in crude oil production, and cardiopulmonary bypass surgery. Focusing on the basic science of defoaming, this book presents a balanced view, which also addresses the challenges that may arise for these specific defoaming applications.
