Surfactants perform a wide range of functions in tribology. These include basic lubrication functions such as control of friction and wear, as well as controlling a wide range of lubricant properties. Examples of lubricant properties that can be modified with the application of surfactants include: emulsification/demulsification, bioresistance, oxidation resistant, rust/corrosion prevention, etc. Surfactants also spontaneously form a wide range of organized assemblies in polar and non-polar solvents. These include, monolayers; normal/reverse micelles; o/w and w/or microemulsions; hexagonal and lamellar lyotropic liquid crystals; and uni- and multi-lamellar vesicles. Surface science and tribology play many critical roles in various industries. Manufacture and use of consumer and industrial products rely on the application of advanced surface and tribological knowledge. Examples of major industrial sectors that rely on these two disciplines include: mining; agriculture; manufacturing (metals, plastics, wood, automotive, computers, MEMS, NEMS, appliances, planes, rails, etc); construction (homes, roads, bridges, etc); transportation (cars, boats, rails, airplanes); medicine (instruments and diagnostic devices; transplants for knee, hips, and other body parts), and cosmetics. The chapters in Surfactants in Tribology, Volume 6 discuss latest developments highlighting the relevance of surfactants in various tribological phenomena pertaining to many and different situations. The information compiled in this book will be a valuable resource to scientists and technologists working or entering in the fields of tribolody and surface science. Book jacket.
