Team at Lanzhou Institute of Chemical Physics made unexpected finding while folding ultra-thin sheets of graphene
The researchers from the Lanzhou Institute of Chemical Physics found that friction did not increase as the material got thicker. In fact, some of the thicker folds slid more easily.
The revelation was a bonus for the team – not only had they become the first to directly observe friction between solid materials at the quantum level, they had seen something that could help with the development of ultra-efficient machines and tiny devices that barely wear out.
