Cold self-lubrication of sliding ice
Achraf Atila, Sergey V. Sukhomlinov, Martin H. Müser
The low kinetic friction between ice and numerous counterbodies is commonly attributed to an interfacial water layer, which is believed to originate from pre-existing surface water…

Brittleness of metallic glasses dictated by their state at the fragile-to-strong transition temperature
Achraf Atila, Sergey V. Sukhomlinov, Marc J. Honecker +1
The effect of cooling on the brittleness of glasses in general, and bulk metallic glasses (BMGs) in particular, is usually studied with continuously varying cooling rates; slower c…

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…
