Origins of Friction

A one million dollar question for a tribologist is as follows: where does the friction come from? Despite the undeniable progress in tribology in recent years, this question remains there. But there is a light […]

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 […]

Evolving friction of graphene

Two-dimensional materials are defined as substances with the thickness less than few nanometers. While there may exist around 500 of various 2D materials, the first discovered 2D material is graphene. Graphene is flexible, transparent, possesses […]
