Graphene nanoribbons can slide across gold atoms without almost any friction, according to new experiments by researchers in Switzerland, Japan and Germany. Graphene’s superlubricity means that it could be used as an ultrasmooth coating in machine components, so drastically reducing energy losses in these machines. Nanoribbon coatings might also help to considerably increase the lifetime of micro- and nanoelectromechanical systems (MEMS and NEMS) or even larger-scale objects………
