Contact Area vs. Load: Simple Scaling Laws

04.07.2016 Aydar Akchurin

“God made the bulk; surfaces were invented by the devil”, a Nobel prize winning physicist Wolfgang Ernst Pauli said. In tribology, as in many other sciences, surface features (asperities, roughness) play an important role. In […]

Controlling friction of graphene

02.02.2017

Graphene, a wonder just one atom thick material, shows incredible wear-resistance and super low friction levels. This behavior is ascribed to its low inter-layer shear properties and high normal load carrying capabilities. However, in many [...]
Bio-based material stronger than steel and spider silk altogether

16.05.2018

Researchers at KTH have produced a bio-based material that is reported to surpass the strength of all known bio-based materials whether fabricated or natural, including wood and spider silk. Working with cellulose nanofibre (CNF), the [...]

Friction in Only One Direction

07.07.2019

Nature has amazed us since the beginning of time. It provides the foundation for all of our best ideas. The animal world provides the inspiration behind one of the new inventions in the world of [...]
The Science of Friction on Graphene

12.08.2017

Sliding on flexible graphene surfaces has been uncharted territory until now, Graphene, a two-dimensional form of carbon sheets just one atom thick, has been the subject of widespread research, in large part because of its [...]
Estimation of functional properties of coatings by different tribological test methods
