Surface interaction research focuses on the study of how various materials interact with different surfaces or interfaces. This includes understanding the physical, chemical, and mechanical interactions that occur when two materials come into contact. Surface interaction research is important in various fields such as materials science, chemistry, physics, and engineering, as it can help in developing new materials, improving manufacturing processes, and understanding the behavior of materials at the atomic or molecular level. Some key areas of focus in surface interaction research include adhesion, friction, lubrication, and wear.
