Graphene offers versatile potential for coating machine components and in the field of electronic switches. An international team of researchers led by physicists at the University of Basel have been studying the lubricity of this material on the nanometer scale. Since it produces almost no friction at all, it could drastically reduce energy loss in machines when used as a coating. In future, graphene could be used as an extremely thin coating, resulting in almost zero energy loss between mechanical parts. This is based on superlubricity of modified carbon in the form of graphene...
