Superlubricity and nanotechnology

Superlubricity is a phenomenon where two surfaces slide over each other with barely any resistance (a state that is called near-zero friction). This is a very special case where friction almost vanishes between two surfaces. The difficulty of achieving superlubricity in mechanical systems is due to the very complex physical, chemical, and mechanical interactions that occur simultaneously at the sliding interfaces of these systems. Superlubricity is one of the most promising properties of functional nanomaterials for energy saving applications.
