Environmental Molecular Effect on the Macroscale Friction Behaviors of Graphene [PDF]

open access: yes, 2021
This study investigated the friction behavior of graphene in air and nitrogen atmosphere environments. The microstructural evolution caused by the variation of atmosphere environments and its effect on the friction coefficient of the graphene is explored.

Interlayer shear strength of single crystalline graphite

open access: yes, 2012
Reported values (0.2 MPa ~ 7.0 GPa) of the interlayer shear strength (ISS) of graphite are very dispersed. The main challenge to obtain a reliable value of ISS is the lack of precise experimental methods.

Direct microscopic evidence of shear induced graphitization of ultrananocrystalline diamond films

open access: yes, 2021
The origin of ultralow friction and high wear resistance in ultrananocrystalline diamond (UNCD) films is still under active debate because of the perplexed tribochemistry at the sliding interface.

Tribological behaviour of Ti3C2Tx nano-sheets: Substrate-dependent tribo-chemical reactions [PDF]

open access: yes, 2023
MXenes, a newly emerging class of layered two dimensional (2D) materials, are promising solid lubricants due to their 2D structure consisting of weakly-bonded layers with a low shear strength and ability to form beneficial tribo-layers. This work aims at

Structural Superlubricity of Two-Dimensional Materials: Mechanisms, Properties, Influencing Factors, and Applications

open access: yesLubricants
Structural superlubricity refers to the lubrication state in which the friction between two crystalline surfaces in incommensurate contact is nearly zero; this has become an important branch in recent tribological research. Two-dimensional (2D) materials
