Is Ultralow Friction on Graphite Sustainable in Contaminated Environments?
Hongyu Gao, Sergey Sukhomlinov
Structural lubricity arises typically at incommensurate, well-defined dry contacts where short-range elastic instability is significantly mitigated. However, under ambient conditio…

Structural Lubricity and Molecular Contamination: Rejuvenation, Aging, and Friction Switches
Wai H. Oo, Hongyu Gao, Martin H. Müser +1
Using atomic force microscopy experiments and molecular dynamics simulations of gold nanoislands on graphite, we investigate why ultra-small friction commonly associated with struc…

On the shear-thinning of alkanes
Hongyu Gao, Martin H. Müser
The approximate power-law dependence of the apparent viscosity of liquids on shear rate is often argued to arise from a distribution of energy barriers. However, recent work on the…
