Achieving superlubricity with 2D transition metal carbides (MXenes) and MXene/graphene coatings [PDF]
Materials Today Advances, 2021 Two-dimensional (2D) materials have demonstrated unique friction and antiwear properties unmatched by their bulk (3D) counterparts. A relatively new, large and quickly growing family of two-dimensional early transition metal carbides and nitrides (MXenes)

Macroscale superlubricity enabled by graphene nanoscroll formation [PDF]
Science, 2015 Slip sliding away Many applications would benefit from ultralow friction conditions to minimize wear on the moving parts such as in hard drives or engines. On the very small scale, ultralow friction has been observed with graphite as a lubricant. Berman et al.

Insight into macroscale superlubricity of polyol aqueous solution induced by protic ionic liquid
Friction, 2022 Currently, macroscale liquid superlubricity remains limited to low applied loads and typical ceramic friction pairs. In this study, a robust macroscale superlubricity with a coefficient of friction (COF) of approximately 0.006 is realized at the bearing ...
