The manufacture and use of almost every consumer and industrial product rely on application of advanced knowledge in surface science and tribology. These two disciplines are of critical importance in major economic sectors, such as mining, agriculture, manufacturing (including metals, plastics, wood, computers, MEMS, NEMS, appliances), construction, transportation, and medical instruments, transplants, and diagnostic devices. An up-to-date reference with contributions by experts in surface science and tribology, Surfactants in Tribology, Volume 3 discusses some of the underlying tribological and surface science issues relevant to many situations in diverse industries.The tradition of presenting new developments and research that began with the first volume in this groundbreaking series continues in the third volume. Comprising 19 chapters on various aspects of surfactants in tribology—including subjects not covered in previous volumes—this book is presented in four parts: Nanotribology and Polymeric Systems, Biobased and Environmentally Friendly Lubricants and Additives, Tribological Properties of Aqueous and Nonaqueous Systems, and Advanced Tribological Concepts. Topics include tribological properties of nanoparticles, biopolymer friction, environmentally friendly surface-active agents, biolubricants, aqueous mixed surfactant systems, and surfactants in motor oil, drilling fluids, and in electrowetting for MEMS and NEMS.The information in this volume provides a cutting-edge reference connecting the fields of surfactants and tribology as a way forward to novel, enhanced methods of controlling lubrication, friction, and wear. Written by a global team of established authorities, this book reflects the latest developments, highlighting the relevance of surfactants in tribological phenomena in a broad range of industries. It provides a valuable resource for readers working in or entering the fields of

The premier symposium on Surfactants in Tribology, held in Seoul in 2006, was an enormously successful event that generated a high level of interest in the topic, leading to the publication of the first volume in this series in 2008. The tremendous response was echoed at the follow-up symposium in Berlin that same year, and leading researchers, many of whom participated in the second event, were invited to submit chapters for Surfactants in Tribology, Volume Two. Reflecting the cumulative wisdom of a contingent of researchers, this text explores all-new topics critical to the future of tribology.Topics discussed in this second volume include: Properties of silane, thio, phthalocyanine and phospholipid films, membranes, grafts, and SAMs on gold, silica, and graphite substratesWater/oil emulsions used as oil-well drilling fluidsProperties of organized surfactant assemblies and aqueous solutions of alkyl polyglucosidesSurfactants as demulsifiers in enhanced crude oil production from old wells Oil/water emulsions with biobased surfactantsThe synthesis of novel biobased materialsProperties of biobased lubricants and surfactantsModeling and statistical predictive methods in the development of biobased lubricantsThe fundamentals of surface chemistry at tribological interfacesThe role of surface science in magnetic recording tribologyAntiwear and friction modifier compounds for automotive applicationsSurfactants as antimicrobial agents in lubricants Tribological phenomena are of significant importance in a host of industries ranging from simple products to high-tech devices.

Surfactants play a critical role in Tribology controlling friction, wear, and lubricant properties such as emulsification, demulsification, bioresistance, oxidation resistance, rust prevention and corrosion resistance. This is a critical topic for new materials and devices particularly those built at the nanoscale. This newest volume will address tribological properties of cutting fluids, lubricant performance related to steel surfaces, biolubricants, and novel materials and ways to reduce friction and wear. Scientists from industrial research and development (R&D) organizations and academic research teams in Asia, Europe, the Middle East and North America will participate in the work.

A Comprehensive Review of Developing Environmentally Friendly LubricantsA push from environmentally savvy consumers along with recent changes in governmental regulations have paved the way for a marketplace of products with high levels of environmental performance. Fueled by the growing demand for biobased lubricants, Environmentally Friendly and Biobased Lubricants highlights the development of environmentally friendly additives that are compatible with environmental regulations and describes the approaches being used in this emerging area.Derived from research topics shared over the years at various technical sessions of the Society of Tribologists and Lubrication Engineers (STLE) Annual Meetings, the book includes a critical assessment of gaps and weaknesses in the field of environmentally friendly fluids and biobased lubricants. Each chapter is written by authors selected from the environmentally friendly fluids and biobased lubricants sessions of STLE and also incorporates input from prominent researchers invited to take part in the book. Expert contributors discuss the control, production, usage, and disposal of lubricants; factor in related policies, laws, and regulations around the world; and include case studies demonstrating the uses and values of commercially viable biobased lubricants.The book is divided into five sections that cover advanced environmentally friendly base oils and feedstocks, biobased hydraulic lubricants and biodegradability, chemically/enzymatically modified environmentally friendly base oils, vegetable oil–based environmentally friendly fluids, and additives for environmentally friendly fluids.
