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 […]

Superlubricity with Green Lubricant

Superlubricity is a state of vanishing sliding friction. It has been reported in glycerol/water mixture lubricated contacts, graphene-gold interface,  interface in presence of graphene and in other conditions. Increasing number of reports on superlubricity in […]

Slip, No Slip and Cavitation

Engineering surfaces are heterogeneous and can be slippery or sticky locally depending on surface roughness and chemistry. The variation of surface properties affects the interaction between the wall and lubricant and determines friction. Slip can […]
