Abstract
An ultralubricated system is reported which confines a monolayer between graphite plates. molecules act as molecular bearings, assisted by the nanogears of six-membered carbon rings between molecules and graphite, in which the mean dynamical frictional forces are zero up to a high load of 100 nanonewtons. A stick-slip rolling model with a step rotation of a molecule is proposed. This ultralubricated system, very promising for the realization of nano- and micromachines, is expected to open a new field of molecular bearings.
