What is Boundary Lubrication? [avatar user=”James Ewen” size=”original” align=”left” link=”https://www.linkedin.com/in/james-ewen/“] The article was created by Dr. James Ewen[/avatar] Boundary lubrication describes situations where the applied load is primarily supported by contacting solid asperities, rather than […]

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 [...]

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 [...]
