Download or read book Upper Limits for the Contact Angles of Liquids on Solids written by Elaine G. Shafrin and published by . This book was released on 1963 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earlier systematic studies of the angle of contact (theta) exhibited by drops of liquid on plane solid surfaces of low surface energy have made data available on equilibrium contact angles. These data were obtained under well-controlled and comparable experimental conditions for many liquids on over 100 different solid surfaces. Examination of the data for eight, selected, pure liquids (water, formamide, methylene iodide, hexachloropropylene, t-butylnaphthalene, dicyclohexyl, n-hexadecane, and n-decane) reveals a wide variation in the wetting behavior of any single liquid toward different solid surfaces. For each liquid, however, graphical plots of cosine theta versus the difference in the surface tension of the pure liquid and the critical surface tension of spreading of the solid are found to group available data into a zone bounded by a straight line passing through the origin. From the parameters defining this straight line, estimates can be made of the limiting contact angles for each liquid. (Author).

Book excerpt: The common perception is that nanoscience is something entirely new, that it sprung forth whole and fully formed like some mythological deity. But the truth is that like all things scientific, nanoscience is the natural result of the long evolution of scientific inquiry. Following a historical trail back to the middle of the 19th century, nanoscience is the inborn property of colloid and interface science. What’s important today is for us to recognize that nanoparticles are small colloidal objects. It should also be appreciated that over the past decades, a number of novel nanostructures have been developed, but whatever we call them, we cannot forget that their properties and behavior are still in the realm of colloid and interface science. However one views it, the interest and funding in nano-science is a tremendous opportunity to advance critical research in colloid chemistry. Nanoscience: Colloidal and Interfacial Aspects brings together a prominent roster of 42 leading investigators and their teams, who detail the wide range of theoretical and experimental knowledge that can be successfully applied for investigating nanosystems, many of which are actually well-known colloidal systems. This international grouping of pioneering investigators from academia and industry use these pages to provide researchers of today and tomorrow with a full examination of nano-disperse colloids, homogeneous and heterogeneous nano-structured materials (and their properties), and shelf-organization at the nano-scale. This cutting-edge reference provides information on investigations into non-linear electrokinetic phenomena in nano-sized dispersions and nano-sized biological systems. It discusses application aspects of technological processes in great detail, providing scientists and engineers across all fields with authoritative commentary on colloid and interface science operating at the nanoscale. Nano-Science: Colloidal and Interfacial Aspects provides an authoritative resource for those wanting to familiarize themselves with current progress as well as for those looking to make their own impact on the development of new technologies and practical applications in fields as diverse as medicine, materials, and environmental science to name but a few. Whether you call the technology nano or colloids, the field continues to be ripe with opportunity.

Download or read book Space Radiator Study written by R. J. Denington and published by . This book was released on 1963 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Design techniques are presented for condenser radiators for condensing mercury, sodium, potassium, and rubidium vapors for Rankine cycle space power plants. Included in the design techniques are radiation heat transfer, fluid mechanics, meteoroid protection and materials considerations, with the fluid mechanics stability aspects emphasized. Parametric data for large alkali metal condenser radiators relating geometry to weight and area are presented. Tests were conducted with water, sodium, potassium, and rubidium to investigate flow regime and stability in vertical up flow condensing. A correlation is presented for predicting the transition from a stable annular film flow to a slugging regime. Techniques for estimating pressure drop and inventory are provided. Condensing heat transfer coefficients for potassium and rubidium are measured and found to vary from 200 to 4000 Btu/hr sq. ft. F at relatively low velocities and pressures. This report summarizes the recommended design procedures, parametric data and the experimental details.

Download or read book Fundamentals of Interface and Colloid Science written by J. Lyklema and published by Elsevier. This book was released on 2000-07-10 with total page 807 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Interface and Colloid Science (FICS) is a standard reference work with an educational nature. The emphasis is on the basic facts and phenomena, which are systematically explained. FICS aims to make interface and colloid science accessible to a wide audience. Interface and colloid science is an important and fascinating field, but one that is often overlooked and undervalued. It has applications as diverse as agriculture, mineral dressing, oil recovery, industrial chemistry, medical science and biotechnology.A deductive approach is followed, with systems of growing complexity being treated as the book progresses. Volume I: Fundamentals (1st ed. 1991, 2nd ed. 1993) reviews the physical chemistry required to understand current literature on interfacial and colloid science. The volume starts from first principles and gradually increases the level. Volume II: Solid-Liquid Interfaces (1995) treats the subject systematically for the first time, including adsorption, double layers and electronkinetics. Volume III: Interface Tension covers interfacial tensions, monolayers and wetting. Accessible to a wide audience without a detailed knowledge of physics and chemistry Complex mathematical derivations are kept to a minimum Treats interfacial and colloidal phenomena from first principles (advanced command of physics and chemistry not required) Takes the reader from elementary to expert level Acts as a reference and a textbook Contains extensive and detailed cumulative subject index

Available in PDF, EPUB and Kindle. Book excerpt: The present volume and its companion Volume 2 document the proceedings of the Symposium on Surface Contamination: Its Genesis, Detection and Control held in Washington, D.C., September 10-13, 1978. This Symposium was a part of the 4th International Symposium on Contamination Control held under the auspices of the International Committee of Contamination Control Societies, and the Institute of Environmental Sciences (U.S.A.) was the official host. The ubiquitous nature of surface contamination causes concern to everyone dealing with surfaces, and the world of surfaces is wide and open-ended. The technological areas where surface clean ing is of cardinal importance are too many and very diversified. To people working in areas such as adhesion, composites, adsorp tion, friction, lubrication, soldering,device fabrication, printed circuit boards, etc., surface contamination has always been a bete noire. In short, people dealing with surfaces are afflicted with molysmophobiat, and rightfully so. In the past, the subject of surface contamination had been discussed in various meetings, but this symposium was hailed as the most comprehensive symposium ever held on this important topic, as the technical program comprised 70 papers by more than 100 authors from 10 countries. The symposium was truly international in scope and spirits and was very well attended. The attendees represented a broad spectrum of backgrounds, interests, and pro fessional affiliations, but all had a common interest and concern about surface contamination and cleaning.
