Surfactants play a critical role in tribology as they control friction, wear, and lubricant properties such as emulsification, demulsification, bioresistance, oxidation resistance, rust prevention, and corrosion resistance. The use of surfactants in tribology is a critical topic for scientists and engineers who are developing new materials and devices, in particular those built at the nanoscale. Edited by a well-known and respected leader in the field, this two-volume set features renowned international contributors who review the latest advances in the tribological aspects of microdevices and nanodevices, including MEMS, NEMS, biosurfactants, biolubricants, and bioemulsions.
