Available in PDF, EPUB and Kindle. Book excerpt: This and its companion Volumes 4 and 6 document the proceedings of the 5th International Symposium on Surfactants in Solution held in Bordeaux, France, July 9-13, 1984. This symposium was the continuation of the series of symposia initiated in 1976 in Albany, New York under the title "Micellization, Solubilization and Microemulsions". The next two symposia were labelled "Solution Chemistry of Surfactants" and "Solution Behavior of Surfactants: Theoretical and Applied Aspects" held in Knoxville, TN in 1978 and Potsdam, N. Y. in 1980, respectively. In 1982 at the time of the 4th Symposium in this series, it became amply evident that there was a definite need to have more a generic title to describe these biennial events, and after much deliberation it was decided that an appropriate title would be "Surfactants in Solution" as both the aggregation and adsorption aspects of surfactants were addressed. So the 4th Symposium was held in 1982 in Lund, Sweden, under this new rubric, and it was decided to continue these symposia in the future under this appellation. Naturally, the Bordeaux Symposium was dubbed as the 5th International Symposium on Surfactants in Solution, and our logo became SIS which is very apropos and appealing. It was in Bordeaux that the decision was made to hold the 6th SIS Symposium in New Delhi and it is scheduled for August 18-22, 1986 in the capital of India.

Available in PDF, EPUB and Kindle. Book excerpt: Macromolecular Solutions: Solvent-Property Relationships in Polymers is a collection of papers presented at a symposium on Macromolecular Solutions, held New York City on August 23-28, 1981, sponsored by the American Chemical Society at its 182nd national meeting. This book is composed of 19 chapters and begins with discussions on the concept, application, and analysis of solubility parameters of polymers. The succeeding chapters deal with the role of solubility parameters in polymer coating design and stress cracking of nylon. Considerable chapters are devoted to the preparation, properties, reactions, and analysis of various polymers and copolymers. These topics are followed by surveys of the polymer-surfactant interaction effect on polymer solution properties and the effects of methanol-gasoline mixtures on elastomers. The final chapters describe the residual solvent content effect on dissolution kinetics of polymers; the application of excimer fluorescence to measure polymer-solvent interactions; and a general procedure for the calculation of thermodynamic properties of polymer solutions. This book will be of great value to polymer chemists, manufacturers, and researchers.
Download or read book The Role of Water in Interfacial Interactions written by Adrian Perez Defante and published by . This book was released on 2016 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: The role of water is often overlooked in interfacial phenomena, but its presence influences many interfacial processes relevant to a number of scientific disciplines. Direct force measurements have offered the most insight into underwater surface related phenomena such as adhesion, wetting, and friction, and have provided molecular descriptions to the physical interactions taking place at the contact interface. Although the insight from these experiments maybe true, there lacks direct molecular confirmation of the assertions interpreted from these force measurements. To address this, we have studied the impact of water on adhesion, friction, and wetting by using a suite of complementary surface sensitive techniques. By using non-linear sum frequency generation spectroscopy, we are able to probe surfaces at a molecular level and connect these chemical details to better understand interfacial phenomena. This thesis focuses on three studies to better understand the role of water in interfacial phenomena. For the first study, we focused on the contact of two hydrophobic surfaces in water. Here, we use surface sensitive sum frequency generation spectroscopy to directly probe the contact interface between hydrophobic poly-(dimethylsiloxane) (PDMS) and two hydrophobic surfaces (a self-assembled monolayer, OTS, and a polymer coating, PVNODC). We show that the interfacial structure for OTS and PVNODC are identical in dry contact but that they differ dramatically in wet contact. In water, the PVNODC surface partially rearranges at grain boundaries, trapping water at the contact interface leading to a 50% reduction in adhesion energy compared to OTS-PDMS contact. The Young-Dupr\'e equation, used extensively to calculate the thermodynamic work of adhesion, predicts no differences between the adhesion energy for these two hydrophobic surfaces, indicating a failure of this well-known equation when there is a heterogeneous contact.For the second study, we studied the role of water between two hydrophilic interfaces in sliding friction and adhesion. We achieve this by adsorbing cationic surfactant, cetyl trimethyl ammonium bromide (CTAB), on two hydrophobic surfaces, PDMS and a self assembled monolayer. Using surface sensitive sum frequency generation spectroscopy, we highlight a strongly coordinated ice-like water layer confined between two surfactant covered hydrophobic surfaces under hydration pressures. Such strongly coordinated water structure, that reduces the sliding friction, forms past the surfactant concentration needed for monolayer coverage. In addition, the surprising observance of a highly coordinated ice like layer of water between these two surfaces presents opportunities for developing a theoretical framework to the molecular behavior of confined water.For the third study, we investigate underwater adhesion and friction for a hydrophobic lens in contact with plasma treated surfaces of different wettability. From these measurements, we aimed to guide the interfacial design of underwater adhesives by systematically varying the surface energy of the contact interface. We show underwater adhesion and friction is the highest between a hydrophobic lens and plasma treated surface for a water contact angle of 70 degrees.

Download or read book Specialist Surfactants written by I.D. Robb and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surfactants are vital components in biological systems, are key ingredients in many formulated products and play an important role in many industrial processes. The property which makes surfactants so useful is their ability to stabilize complex colloidal and interfacial systems. It is not surprising therefore that many new surfactant materials are developed, many of which have novel properties. However because their potential is not fully appreciated they remain underutilized by industry. The main purpose of this book is to illustrate the utility of a range of novel surfactants, in particular those which have been found useful in specific areas and which seem to offer promise across a wider range of applications. The contributors are drawn from industry and academic research and provide a comprehensive account of the preparation, properties and applications of these specialist surfactants. Research chemists in industry and academia will find this book a concise and authoritative account of this important group of surfactants.
