Contact size effects on the friction and wear of amorphous carbon films

Applied Surface Science Advances, 2022
Since different properties of coating systems influence their friction and wear at different length scales contact size can play a critical role in microtribological experiments.

Casimir‐Lifshitz Optical Resonators: A New Platform for Exploring Physics at the Nanoscale

Advanced Physics Research, Volume 3, Issue 2, February 2024.
Levitation, or trapping, of a flat mirror at a certain distance above another flat reflecting surface, as a result of the compensation of attractive gravitational forces by a quantum fluctuation induced repulsive force, leads to the formation of Casimir‐Lifshitz optical resonators, which have opened the possibility to explore a wide range of physical ...

Diffusion equation for spreading and replenishment in submonolayer lubricant film

Nihon Kikai Gakkai ronbunshu, 2014
In magnetic hard disk drives, it is important to evaluate head wear durability in relation to lubricant layer because the head-disk spacing has to be reduced to ~1nm to achieve a high density recording above 1 Tb/in2.

Role of Interfacial Water and Applied Potential on Friction at Au(111) Surfaces

Frontiers in Mechanical Engineering, 2019
The tribological properties between an AFM tip and a Au(111) surface in an aqueous environment is influenced by an applied electrical potential. Using lateral force microscopy, we measure the resulting friction force, while simultaneously applying a pre ...
