Argonne Embraces Concept of "in operando" Formation of Carbon-based Tribofilms

23.08.2016 Rick Shankman 500 Views

Earlier this month, tribologists and physicists at the U.S. Department of Energy (DOE) Argonne National Laboratory published news of their (self-described) “self-healing diamond-like carbon coating [that] could revolutionize lubrication” in the journal Nature. The researchers […]

Switchable Friction on Graphene

15.08.2016 Dr. Aydar Akchurin 298 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 […]

Adhesive Wear Particles Generation: by Fracture or Atom-by-Atom?

01.08.2016 Dr. Aydar Akchurin 598 Views

The most famous equation to predict wear known probably to everyone working in the field of tribology is Archard’s model (1953). The model assumes that wear occurs through the fracture of plastically deformed material and […]

Often, when an individual hears the word diamond, a vision of love and an engagement ring is what first comes to mind. If the first picture is not an engagement ring, then it is typically [...]
Molecular Dynamic Simulations and AFM Experiments at Overlapping Speeds

11.04.2016 408 Views
Atomic Force Microscopy (AFM) is a powerful and convenient experimental measurement device in the field of nano-scale tribology. It was successfully applied to explore superlubricity in a graphene-gold interface and superlubricity due to repulsive van [...]
Ice friction and frictional heat

07.02.2016 327 Views
As it was already pointed in the recent post, the friction on ice is an important topic and its typical low value is attributed to the formation of the water film. Despite our everyday life [...]
Superlubricity with Green Lubricant

12.09.2016 777 Views
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 [...]
