The text discusses the fundamentals of lubrication science and technology linking the science concepts to engineering practices. It further explores the performance characterization of lubrication systems by utilizing sophisticated experiments and tests and motivates the readers to develop their conclusions and reach solutions based on modern tools and techniques. This book: Presents the principles of surface and lubricant chemistry, and its implementation to devise engineering solutions for various application-based systems. Discusses viscosity index improvers, tribology of green lubricants, and biolubricants from non-edible oils. Highlights 2D nanomaterials lubricants, biogreases, hydrogel and lubricants for extreme temperature and pressure conditions.                                                 Explains lubrication for electrical, biomedical, automobile, marine, turbine and aerospace applications.                                                               Covers design considerations, formulations, and compositions of lubricants for high-temperature applications in diverse areas.                                                                       Explores the simulation, computational, and empirical models to characterize, quantify and mitigate the adverse effects of friction. It is primarily written for senior undergraduate and graduate students, and academic researchers in the fields of mechanical engineering, production engineering, industrial engineering, aerospace engineering, and manufacturing engineering.
