Progress in Microemulsions by S. Martellucci,A.N. Chester Pdf

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.

Microemulsions: Structure and Dynamics by Friberg Pdf

This book describes the microemulsion phenomenon in a systematic manner and not only provides an up-to-date introduction to this topic but aslo serves as the basis for further development in the area.The progress of microemulsion research has taken place in well-defined stages. The introduction period was founded on Schulman‘s original discovery and was, as expected, focused on the interfacial free energy. Because Schulman obtained his microemulsions from a macroemulsion by the addition of a cosurfactant.The present stage is characterized by an extensively enhanced knowledge about structure and dynamics in these systems. This has led to the realization that the structure of the microemulsions is related both to solutions with critical behaviour and long range order structures, the lyotropic liquid crystals. These two aspects have been elucidated independently by the French groups and by the Lund Spectroscopy group.

Microemulsions and Related Systems by Maurice Bourrel,Robert Samuel Schechter Pdf

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.

Microemulsions Theory and Practice by Leon Prince Pdf

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.

Microemulsions by Monzer Fanun Pdf

The effective use of microemulsions has increased dramatically during the past few decades as major industrial applications have expanded in a variety of fields. Microemulsions: Properties and Applications provides a complete and systematic assessment of all topics affecting microemulsion performance and discusses the fundamental characteristics, theories, and applications of these dispersions. Thoroughly encompassing the significant developments of the past ten years, this book describes a wide range of topics, including interactions at microemulsion interfaces, new types of surfactants, and the fundamentals of nanotechnology. It outlines experimental and traditional measurement techniques in a variety of microemulsified systems and provides reliable coverage of applicable techniques. Theory and Characterization Methods The initial chapters cover theoretical aspects of microemulsion formulation, with particular focus on methodologies for preparation. The book also addresses characterization methods, including X-ray diffraction, transmission electron microscopy (TEM), light scattering, and small-angle neutron scattering. It includes discussions of viscosimetry, conductivity, ultrasonic velocity, and nuclear magnetic resonance (NMR). Practical Applications The remainder of the coverage focuses on current and potential applications of microemulsions. The book examines commercial uses, including biocatalysis and enzymatic reactions, nutrition, the extraction of contaminated solids, pollution control, dispersion of drugs, and oil recovery. The contributors also discuss the use of microemulsions as a reaction medium for the formation of polymeric and inorganic nanoparticles, and applications in electrokinetic chromatography. Comprising the work of an international community of colloid scientists, this book explains why microemulsions are used for the intended application, how they are made, and how they react. Each chapter contains a description of the fundamental phenomena and principles involved in microemulsion processes, emphasizing the mechanism of microemulsion formation and deformation. A summary of recent research, the book eliminates the need to search through dozens of arcane online journal articles for critical information.

Properties and Uses of Microemulsions by Desiree Nedra Karunaratne,Geethy Pamunuwa,R. J. K. U. Ranatunga Pdf

Properties and Uses of Microemulsions is intended to provide the reader with some important applications and features of these systems. The intricate composition of microemulsions has made them applicable in many areas such as cosmetics, pharmaceuticals, food, agriculture, oil recovery, chemical synthesis of nanoparticles, and catalysts. An introductory chapter starts off with the description of these applications followed by methods of characterization. Thereafter, a few practical applications of microemulsions focusing on drug delivery, oil recovery, and formation of nanocatalysts are described followed by the third section discussing the theoretical and physical parameters predicting microemulsion properties. The use of spin-polarized paramagnetic probes, bending energetics, and study of self-propelled motion are some of the physical parameters employed to characterize the microemulsions.

Micelles, Membranes, Microemulsions, and Monolayers by William M. Gelbart,Avinoam Ben-Shaul,Didier Roux Pdf

Over the last decades, the study of surfactants (detergents, for example) has been profoundly changed by ideas and techniques from physics, chemistry, and materials science. Among these are: self assembly; critical phenomena, scaling, and renormalization; high-resolution scattering, and magnetic resonance spectroscopy. This book represents the first systematic account of these new developments, providing both a general introduction to the subject as well as a review of recent developments. The book will be a very useful tool for the biophysist, biochemist or physical chemist working in the field of surfactants.
