Controlling friction of graphene

02.02.2017 Aydar Akchurin 895 Views
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 […]

Slip, No Slip and Cavitation

05.09.2016 Aydar Akchurin 1518 Views
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 […]

Switchable Friction on Graphene

15.08.2016 Aydar Akchurin 549 Views
Graphene is a unique material in many aspects and has recently been applied in various ways. In tribology, it has been shown to lead to a superlubricity – an ultra low friction state. In laboratory […]
