Lubricants are substances used to reduce friction between surfaces in relative motion, thereby minimizing wear and heat generation. They are commonly used in machinery, vehicles, and industrial processes to ensure smooth operation and prolong the lifespan of mechanical components. Different types of lubricants, such as oils, greases, and solid lubricants, are used based on the specific application and operating conditions. Research in lubricants focuses on developing new formulations, improving performance characteristics, and addressing environmental and health concerns associated with their use. This research area also explores innovative lubrication technologies, such as nanolubricants and bio-based lubricants, to meet the evolving needs of various industries.
