This volume, drawn from papers presented at a symposium held in Seoul, Korea in June 2006, as well as original submissions from leading researchers, presents recent developments and research activities which highlight the importance of surfactants in tribological phenomena. With an emphasis on product development, the book provides a nanoscale understanding of surfactants, considers practical applications for MEMs, NEMs, and biodevices, covers various tribological phenomena, discusses industry-specific applications for automotive and other uses, and more.

From the Preface: “...Surfactants play a variety of critical roles in tribology, which subsumes the phenomena of three processes: friction, wear, and lubrication. The most widely recognized role of surfactants deals with their ability to control friction and wear. Surfactants also allow for control of a wide range of properties of lubricants, such as emulsification/demulsification, bioresistance, oxidation resistance, rust/corrosion prevention, etc. This book is a compendium of recent advances dealing with the role of surfactants in all three subjects within the purview of tribology...”

Target Audience: Chemists; chemical, petroleum, and automotive engineers; lubricant formulators; materials scientists; tribologists; and technologists studying MEMs, NEMs, SAMs, and biodevices.
