Download Progress in Microemulsions Book in PDF, ePub and Kindle
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.

Download Microemulsions: Structure and Dynamics Book in PDF, ePub and Kindle
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.

Download Progress and first milestones in formulating food-grade microemulsions Book in PDF, ePub and Kindle
In every day life the immiscibility of polar and non-polar components is a common problem. For instance molten chocolate coating already firms up, if it encounters the slightest bit of water. A smart possibility to overcome this problem is the use of microemulsions, which contain at least a polar, non-polar and an amphiphilic component. The formulation of bio compatible microemulsions is limited by the choice of surfactants permissible for applications in food, pharmaceutics and cosmetics. This work presents a progress and first milestones in formulating food-grade microemulsions which are suitable for all these applications. Triglycerides and phospholipids are edible, organic and thus the favored components. Microemulsions based on these were investigated. The first milestones towards the formulation of food-grade microemulsions are presented. Performed SANS measurements show, that microemulsions of the type H2O/NaCl – triglyceride – phospholipid – edible co-surfactant exhibit a bicontinuous structure. Systematic studies were performed on how these microemulsions can be tuned regarding temperature range, surfactant mass fraction and structure. Therefore, the influence of bio-compatible hydrophilic, hydrophobic and amphiphilic components on the phase behavior was investigated separately in well known (not food acceptable) model systems. Based on this work, a novel technique to introduce a polar into a non-polar phase and vice versa using a microemulsion or lamellar phase at low surfactant mass fractions was developed. This new invention of eXpandible moisture adapting sheets (X-mas) highlights the many possibilities of edible microemulsion for industrial exploitation.

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.
