Superlubricity

Superlubricity is a recently invented term in tribology, which is generally defined as the state, at which the friction coefficient is low. The definition of “low” is not quite clear, but it can be assumed […]

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 […]

So, what is it, superlubricity?

From the first friction quantitative experiments by Leonardo da Vinci (1452-1519) and most notably from our everyday life experience, it is known that there is an inevitable force opposing to the initiation of motion of […]
