Ab Initio Analysis of Carbon Film Lubricity

16.05.2016 Dr. Aydar Akchurin 234 Views

Carbon-based nanomaterials, coatings and films attracted a great attention due to proved possibility to achieve lowest friction and wear without environmental pollution. However, frequently, the state of the low friction is strictly related to the […]

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

01.08.2016 575 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 [...]
New Stretchability Record Set by Nanogenerator

21.10.2019 121 Views

A nanogenerator has set a new record by stretching in a manner similar to rubber band to more than 25 times its original length. This represents a 2500% stretchability factor, which beats the previous record [...]
Switchable Friction on Graphene

15.08.2016 271 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 [...]
Modeling rough adhesive surfaces

Imagine a new type of tyres whose structure has been designed to have greater adhesion on the road. Quite a timely discussion during the long winter nights. French physicists have now developed a model to [...]
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 [...]
