Frictional temperature rise in a sliding physisorbed monolayer of Kr/graphene.
TL;DR: A quartz crystal microbalance with a graphene/Ni(111) electrode has been used to probe frictional heating effects in Kr monolayers sliding on the microbalance electrode in response to its oscillatory motion, showing surprisingly little dependence on oscillation amplitude.

Abstract: A quartz crystal microbalance (QCM) with a graphene/Ni(111) electrode has been used to probe frictional heating effects in Kr monolayers sliding on the microbalance electrode in response to its oscillatory motion. The temperatures of the sliding Kr monolayers are observed to rise approximately 13 K higher than their static counterparts, but show surprisingly little dependence on oscillation amplitude. Although counterintuitive, the observation can be explained by noting that the Kr surface residence times are limited, which effectively caps how much the temperature can rise.

Approaches for Achieving Superlubricity in Two-Dimensional Materials.
TL;DR: This review outlines basic mechanisms for frictional energy dissipation during sliding of two surfaces against each other, and the procedures for manipulating friction and wear by introducing 2D materials at the tribological interface, and highlights recent progress in implementing2D materials for friction reduction to near-zero values-superlubricity-across scales from nano- up to macroscale contacts.

TL;DR: The force required to slide one- and two-atom-thick solid films of xenon along a Ag(111) surface is measured, and it is observed that the friction associated with the bilayer is approximately 25% greater than thatassociated with the monolayer.

Experimental observation of interfacial slippage at the boundary of molecularly thin films with gold substrates
TL;DR: The data provide strong evidence that the excess dissipation arises from slippage at the film substrate interface since the film thicknesses studied are negligible compared to the viscous penetration depths of the respective materials.

Scanning tunneling microscope measurements of the amplitude of vibration of a quartz crystal oscillator
TL;DR: In this article, the vibrational amplitude of a transverse shear mode quartz resonator was measured by directly imaging the surface oscillatory motion with a scanning tunneling microscope, and the results confirmed theoretical predictions to within a factor of two.
Triple point of the first monomolecular layer of krypton adsorbed on the cleavage face of graphite. Influence of the structure of this surface on the structure of the first adsorbed layer of rare gases
TL;DR: From adsorption isotherms of krypton on graphite measured between 79.24 and 88.46 K in the monolayer domain, a two-dimensional triple point of 84.8 ± 0.5 K is determined for this system as discussed by the authors.
