TL;DR: This work reports a direct measurement of sliding friction between graphene and graphene, and graphene and hexagonal boron nitride (h-BN) under high contact pressures by employing graphene-coated microsphere (GMS) probe prepared by metal-catalyst-free chemical vapour deposition.

TL;DR: In present work, a superlubricity phenomenon of phosphoric acid (H(3)PO(4)) was found under ambient conditions and the experimental results indicate that the superlow friction state was very stable for more than 3 h.

TL;DR: Structural analysis of the carbonaceous sliding interfaces at the atomic scale in two superlubricious solid lubricants are presented by probing the contact area using state-of-the-art scanning electron transmission microscopy and electron energy-loss spectroscopy to suggest that the occurrence of a superl lubrication state is generally dependent on the formation of interfacial nanostructures, mainly a tribolayer, by different carbon rehybridization pathways.

TL;DR: The possible superlubricity mechanism has been revealed, which is attributed to a fluid-hydrated water layer between the hydrogen-bonded networks of glycerol and water molecules on the positively charged surfaces.

TL;DR: In this article, the synergy effect of graphene oxide nanoflakes (GONFs) and ethanediol (EDO) at Si3N4-SiO2 interfaces is reported.
