Sliding on a Nanotube: Interplay of Friction, Deformations and Structure
Hsiang-Chih Chiu, Beate Ritz, Suenne Kim +3
The frictional properties of individual carbon nanotubes (CNTs) are studied by sliding an atomic force microscopy tip across and along its principle axis. This direction-dependent…
High-pressure lubricity at the meso- and nanoscale
A. Vanossi, A. Benassi, N. Varini +1
The increase of sliding friction upon increasing load is a classic in the macroscopic world. Here we discuss the possibility that friction rise might sometimes turn into a drop whe…
Structure change, layer sliding, and metallization in high-pressure MoS
Liliana Hromadová, Roman Martoňák, Erio Tosatti
Based on ab initio calculations and metadynamics simulations, we predict that 2H-MoS, a layered insulator, will metallize under pressures in excess of 20-30 GPa. In the same pr…
