Superlubricity is a regime in which friction vanishes or very nearly vanishes. Superlubricity occurs when two crystalline surfaces slide over each other in dry, incommensurate contact. It is an effect that has been already suggested in 1991 but has recently been measured with great accuracy between two graphite surfaces. One should note that the similarity of the term superlubricity with terms such as superconductivity and superfluidity is misleading; other energy dissipation mechanisms can lead… (More on Superlubricity)
