Superlubricity by means of repulsive van der Waals forces

06.04.2016 Dr. Aydar Akchurin 808 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 […]
