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.

Micellar Solutions and Microemulsions by Sow Hsin Chen,Raj Rajagopalan Pdf

During the last decade there has been a renewed interest in research on supramolecular assemblies in solutions, such as micelles and microemulsions, not only because of their extensive applications in industries dealing with catalysts, detergency, biotechnology, and enhanced oil recovery, but also due to the development of new and more powerful experimental and theoretical tools for probing the microscopic behavior of these systems. Prominent among the array of the newly available experimental techniques are photon correlation spectroscopy, small-angle neutron and X-ray scattering, and neutron spin-echo and nuclear magnetic resonance spectroscopies. On the theoretical side, the traditionally emphasized thermodynamic approach to the study of the phase behavior of self-assembled systems in solutions is gradually being replaced by statistical mechanical studies of semi-micro scopic and microscopic models of the assemblies. Since the statistical mechanical approach demands as its starting point the microscopic struc tural information of the self-assembled system, the experimental determina tion of the structures of micelles and microemulsions becomes of paramount interest. In this regard the scattering techniques mentioned above have played an important role in recent years and will continue to do so in the future. In applying the scattering techniques to the supramolecular species in solution, one cannot often regard the solution to be ideal. This is because the inter-aggregate interaction is often long-ranged since it is coulombic in nature and the interparticle correlations are thus appreciable.

Structure and Dynamics of Strongly Interacting Colloids and Supramolecular Aggregates in Solution by Sow-Hsin Chen,John S. Huang,Piero Tartaglia Pdf

During the last decade, various powerful experimental tools have been developed, such as small angle X-ray and neutron scattering, X-ray and neutron reflection from interfaces, neutron spin-echo spectroscopy and quasi-elastic multiple light scattering and large scale computer simulations. Due to the rapid progress brought about by these techniques, one witnesses a resurgence of interest in the physicochemical properties of colloids, surfactants and macromolecules in solution. Although these disciplines have a long history, they are at present rapidly transforming into a new, interdisciplinary research area generally known as complex liquids or soft condensed matter physics: names that reflect the considerable involvement of the chemical and condensed matter physicists. This book is based on lectures given at a NATO ASI held in the summer of 1991 and discusses these new developments, both in theory and experiment. It constitutes the most up-to-date and comprehensive summary of the entire field.

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.

Emulsions, Foams, and Suspensions by Laurier L. Schramm Pdf

Until now colloid science books have either been theoretical, or focused on specific types of dispersion, or on specific applications. This then is the first book to provide an integrated introduction to the nature, formation and occurrence, stability, propagation, and uses of the most common types of colloidal dispersion in the process-related industries. The primary focus is on the applications of the principles, paying attention to practical processes and problems. This is done both as part of the treatment of the fundamentals, where appropriate, and also in the separate sections devoted to specific kinds of industries. Throughout, the treatment is integrated, with the principles of colloid and interface science common to each dispersion type presented for each major physical property class, followed by separate treatments of features unique to emulsions, foams, or suspensions. The first half of the book introduces the fundamental principles, introducing readers to suspension formation and stability, characterization, and flow properties, emphasizing practical aspects throughout. The following chapters discuss a wide range of industrial applications and examples, serving to emphasize the different methodologies that have been successfully applied. Overall, the book shows how to approach making emulsions, foams, and suspensions with different useful properties, how to propagate them, and how to prevent their formation or destabilize them if necessary. The author assumes no prior knowledge of colloid chemistry and, with its glossary of key terms, complete cross-referencing and indexing, this is a must-have for graduate and professional scientists and engineers who may encounter or use emulsions, foams, or suspensions, or combinations thereof, whether in process design, industrial production, or in related R&D fields.

Dynamics of Soft Matter by VICTORIA GARCIA SAKAI,Christiane Alba-Simionesco,Sow Hsin Chen Pdf

Dynamics of Soft Matter: Neutron Applications provides an overview of neutron scattering techniques that measure temporal and spatial correlations simultaneously, at the microscopic and/or mesoscopic scale. These techniques offer answers to new questions arising at the interface of physics, chemistry, and biology. Knowledge of the dynamics at these levels is crucial to understanding the soft matter field, which includes colloids, polymers, membranes, biological macromolecules, foams, emulsions towards biological & biomimetic systems, and phenomena involving wetting, friction, adhesion, or microfluidics. Emphasizing the complementarities of scattering techniques with other spectroscopic ones, this volume also highlights the potential gain in combining techniques such as rheology, NMR, light scattering, dielectric spectroscopy, as well as synchrotron radiation experiments. Key areas covered include polymer science, biological materials, complex fluids and surface science.
