Man lubricates mostly with oil. Nature lubricates exclusively with water. Pure water is a poor lubricant, but the addition of proteins, especially glycoproteins, can modify surfaces to make them far more lubricating at slow speeds. Understanding how nature does this, and the physical structures involved, is not only important for the understanding of diseases such as osteoarthritis, but also essential for the successful application of articulating implants, such as hips and knees, as well as the development of medical devices such as catheters and contact lenses. A host of important applications of water-based lubrication are already in place in the personal care and food industries, and further industrial applications of water-based lubrication could have a significant positive impact on the environment.This book is the first of its kind. It brings together the latest research in biological and biomimetic, water-based lubrication and is authored by the world's experts in the field.
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.
The focus of the book is the modification of surfaces to tailor them for a specific purpose. Using this method of surface modification, materials chosen for their bulk properties (tensile strength, temperature stability, density, price can be optimized for any particular application, which can lead to improved hardness, biological inertness or activity, corrosion resistance, low or high friction or adhesion, water repellency or wettability, or catalytic activity. The works of the author — many of his crucial papers are included — touches upon these surface properties and spans fields including catalysis, analytical surface science, self-assembled monolayers, tribology, biomaterials, superhydrophobicity and polymer coatings.
Written and edited by a team of industry experts, this exciting new volume covers the field of renewable lubricants, their processing, optimization, end-use application, and their future potential. Biolubricants are a viable alternative to synthetic lubricants because they are produced from organic materials such as plant oils, waste oils and by-products. Renewable biolubricants are the subject of research because of their biodegradability, eco-friendliness, and favorable socioeconomic consequences to counteract imitations of synthetic lubricants. Biolubricants have thus emerged as an ideal substitute for mineral oil-based lubricants, as significant economic and environmental acceptability has been received over the last few decades and it has been estimated that there would be a further steady growth in its demand over the next few decades. Furthermore, biolubricants’ high-quality lubricating properties, high load carrying ability, long service life, and fast biodegradability have expanded the recent interest. These lubricants can be derived from different sources of vegetable oils, non-edible oils, waste cooking oils (WCO) and microbe-derived oils. Among all these sources, the use of WCOs and microbe-derived oils have received immense interest and provide superior quality biolubricants. This outstanding new volume covers the prospects and processing of feedstocks for biolubricants, extraction techniques, new advancements in the field of bio-based lubricants, epoxide lubricants, hydrogenated lubricants, microbial-based biolubricants, nano-biolubricants, polyester-based biolubricants, lubricants from waste oils and waste materials, its economic and environmental acceptability and biorefinery approaches. The book will be helpful to industry professionals and engineers of all types, students, and other stakeholders working in the field of lubricant, chemical engineering, mechanical engineering and material science, tribological sectors and biorefinery industries. It will also be of great interest to new start-up companies working in the area of processing feedstocks for biolubricant production and end use application, biorefineries, valorization of biolubricant waste, and in the recycling industries.
Superlubricity is defined as a sliding regime in which friction or resistance to sliding vanishes. It has been shown that energy can be conserved by further reducing/removing friction in moving mechanical systems and this book includes contributions from world-renowned scientists who address some of the most fundamental research issues in overcoming friction. Superlubricity reviews the latest methods and materials in this area of research that are aimed at removing friction in nano-to-micro scale machines and large scale engineering components. Insight is also given into the atomic-scale origins of friction in general and superlubricity while other chapters focus on experimental and practical aspects or impacts of superlubricity that will be very useful for broader industrial community.* Reviews the latest fundamental research in superlubricity today* Presents 'state-of-the-art' methods, materials, and experimental techniques* Latest developments in tribomaterials, coatings, and lubricants providing superlubricity
