Graphene tribolayer adsorption onto steel via perpendicular lattice alignment
Owing to its phenomenal physical properties, graphene continues to be investigated as a new lubricating agent. Recent studies have focused on graphene’s ability to lubricate interacting steel surfaces by its ease of shear capability. […]

Triboelectricity – a big renewable energy source
Tribo-electric effect is an effect of electricity generation, when two dissimilar materials come into contact and electrons migrate from one to another. Most of us have observed the tribo-electric effect in their life when rubbed […]

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 […]
Computational Tribology
Predicting the size of wear particles
A wear process results in the generation of particles, of various size, shape, color and chemical composition. The reported size of wear particles varies from mm scale, which is typically attributed to severe wear, to […]

What contributes to thicker grease films ?
A rolling bearing preferably runs under EHL conditions. The film thickness between the rolling elements and the rings is determined by the lubricant properties, operating conditions and bearing design. During the initial phase of operation, […]
Bio Tribology
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 […]
Computational Tribology
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 […]

Argonne Embraces Concept of “in operando” Formation of Carbon-based Tribofilms
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 […]
Atomistic Tribology
Switchable Friction on Graphene
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 […]
