Book Description
The current state of the art of various aspects of micro emulsion systems is reflected in this volume. Major topics discussed include: general background on solubilized systems, phase diagrams and phase equi libria, bicontinuous microemulsions, Winsor's phases, theories and models of complex self association structures, cry tical behaviour, phase tran sitions in lyotropic liquid crystals. I hope that this book will serve its intended objective of reflecting our current understanding of microemulsions both in theory and practice, and that it will be useful to researchers, both novices as well as experts, as a valuable reference source. I feel indebted to the people of the Ettore Majorana Centre: the friendly atmosphere of the Erice centre provided a very effective environ ment to enjoy the company of colleagues and friends during breaks and after sessions, and to discuss problems of mutual interest. The courtesy, efficiency and devotion of the secretarial and technical staff was also appreciated, and greatly contributed to make the Workshop a smoothly run ning one. The Scientific Secretary Donatella Senatra Department of Physics University of Florence (Italy) v INTRODUCTION The decision to publish. in a more permanent form than heretofore. the Proceedings of the Workshop on "Progress in Microemulsion" of the Inter national School of Quantum Electronics. which was held in Erice (Italy) from October 26 to November 1st. 1985. under the auspices of the "Ettore Majorana" Centre for Scientific Culture. will prove to be a sound one.

Book Description
Microemulsions: Theory and Practice covers the development of the theory and practice of microemulsion systems. This book is divided into seven chapters that explore the physics and chemistry of microemulsions. This book deals first with the commercial history of microemulsions, from the discovery of carnauba wax emulsions to polymer emulsions. This topic is followed by discussions on the theoretical aspects of microemulsion formulation techniques and the design of other products. The subsequent chapter describes the microemulsion formulation with less solubilizer or emulsifier together with their optical properties. A chapter examines the mixed film theory that explains the dispersions, oil-water interface, and inferences in microemulsions. Another chapter considers the role of microemulsions in micellar solutions and their relations to the concentrations of different compounds. This chapter also looks into the association phenomena of three-component phase equilibria diagrams and liquids crystals to microemulsions. The concluding chapter discusses the role of the capillary and hydrostatic forces on the entrapment of oil in the reservoir and the necessary conditions for the displacement of entrapped oil. The important properties and economic aspects of a microemulsion slug required for the tertiary oil recovery are also covered in this chapter.

Book Description
Beginning with P.A. Winsor's fundamental hypothesis on a natural interfacial curvature depending on the values of the formulation variables, this unique book shows scientists how to understand the intrinsic structure of these complex systems and their corresponding physical properties... predict how a change in one formulation variable (surfactant structure, oil structure, aqueous phase composition, temperature, etc.) will modify the microemulsion... and systematically formulate microemulsions for individual applications.This book provides a thermodynamic analysis supporting the existence of natural interfacial curvature... compares the behavior of commercial surfactant mixtures and pure isomeric surfactant molecules in order to point out differences and similarities highly significant for various uses... explains how micelles can evolve smoothly and continuously toward solutions containing large quantities of oil and water... gives procedures for fixing quantitative relationships among formulation variables... plus much more.Illustrated with more than 200 diagrams, tables, and photographs, and completely referenced, this superb volume is essential reading for surfactant, colloid, and physical chemists in both academe and industry, as well as chemical engineers, biotechnologists, and petroleum engineers.Contents: 1. The R-Ratio. 2. Aqueous solutions containing amphiphiles. 3. Nonpolar solutions containing amphiphiles. 4. The phase behavior and properties of solutions containing amphiphiles, organic liquids, and water: micellar solutions. 5. Methods for promoting phase changes. 6. Compensating changes between formulation variables. 7. Solubilization. 8. Thermodynamics of solubilized systems.
