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.

In our present era of nanoscience and nanotechnology, new materials are poised to take center stage in dramatically improving friction and wear behavior under extreme conditions. Compiled by two eminent experts, Self-Organization During Friction: Advanced Surface-Engineered Materials and Systems Design details the latest advances and developments in self-organization phenomena, physical and chemical aspects of friction, and new methods of friction control using advanced materials and coatings.

Using 300 tables to provide experimental data from books, journals, and the patent literature, this practical and comprehensive reference examines: the refining of lube oil base stocks the chemistry of additives the formulation technology of lubricants the performance of the most important finished products such as turbine oils, hydraulic fluids, and engine oils Insight into these variables enables petroleum chemists and engineers to choose the right lubricant base stock and additive combination. By becoming aware of these important elements, those in industry are better able to make the right choices, leading to reduced costs, improved performance, and better management of production timelines.

This textbook discusses the latest advances in the corrosion of metals and related protection methods, and explores all corrosion-related aspects used in natural and industrial environments, including monitoring and testing. Throughout the textbook, the science and engineering of corrosion are merged to help readers perform correct corrosion assessments in both the design phase and plant management phase, and to define the optimal protection technique.
