The Science of Friction on Graphene

Sliding on flexible graphene surfaces has been uncharted territory until now, Graphene, a two-dimensional form of carbon sheets just one atom thick, has been the subject of widespread research, in large part because of its […]

Controlling friction of graphene

Graphene, a wonder just one atom thick material, shows incredible wear-resistance and super low friction levels. This behavior is ascribed to its low inter-layer shear properties and high normal load carrying capabilities. However, in many […]
