Superlubric polycrystalline graphene interfaces

X. Gao, W. Ouyang, et al.

This research by Xiang Gao, Wengen Ouyang, Michael Urbakh, and Oded Hod delves into the fascinating frictional behavior of graphitic contacts with polycrystalline surfaces, uncovering a surprising non-linear relationship between friction, normal load, and temperature. Using a novel two-state model, it offers insights that could potentially enable superlubricity at larger scales.
