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 [...]
Adhesive wear model: particle by particle

23.07.2017 1,775 Views

10.07.17 – An EPFL study has deepened our understanding of the fine particles produced by adhesive wear. This breakthrough could lead to cost savings and environmental benefits. Adhesive wear occurs when two surfaces – such [...]
Superlubricity by means of repulsive van der Waals forces

06.04.2016 810 Views

Superlubricity, a state of low friction (<0.001), can be achieved by different mechanisms. The structural superlubricity occurs, if the crystal lattices of the contacting bodies are incommensurate. Nano-scrolls may act as a bearing and may [...]
Wear in nanoscale: optimum AFM tip roughness

07.03.2016 105 Views

Wear is a gradual removal of the material of the bodies during their interaction. The process appears in many mechanical systems, ranging from large scales, as in wind mills, to nanoscales, as in the AFM [...]
