Interfacial charge density and its connection to adhesion and frictional forces
M. Wolloch, G. Levita, P. Restuccia +1
We derive a connection between the intrinsic tribological properties and the electronic properties of a solid interface. In particular, we show that the adhesion and frictional for…

Tribochemistry of graphene on iron and its possible role in lubrication of steel
Paolo Restuccia, M. C. Righi
Recent tribological experiments revealed that graphene is able to lubricate macroscale steel-on-steel sliding contacts very effectively both in dry and humid conditions. This effec…

A fundamental mechanism for carbon-film lubricity identified by means of ab initio molecular dynamics
Seiji Kajita, Maria Clelia Righi
Different hypotheses have been proposed to explain the mechanism for the extremely low friction coefficient of carbon coatings and its undesired dependence on air humidity. A decis…
