Macroscale Superlubricity Enabled by Graphene‐Coated Surfaces
Advanced Science, 2020 Friction and wear remain the primary modes for energy dissipation in moving mechanical components. Superlubricity is highly desirable for energy saving and environmental benefits.

Macroscale Superlubricity Achieved With Various Liquid Molecules: A Review [PDF]
Frontiers in Mechanical Engineering, 2019 Superlubricity is generally classified as solid superlubricity and liquid superlubricity according to the lubricants involved at the interfaces, and is a popular research topic in tribology, which is closely linked to energy dissipation.

Macroscale Superlubricity of Black Phosphorus Quantum Dots
Lubricants, 2022 In the present work, Black Phosphorus Quantum Dots (BPQDs) were synthesized via sonication-assisted liquid-phase exfoliation. The average size of the BPQDs was 3.3 ± 0.85 nm.

Superlubricity of graphene nanoribbons on gold surfaces [PDF]
Science, 2016 A golden opportunity for graphene Reducing friction can limit wear and improve the energy efficiency of mechanical devices. Graphene is a promising lubricant because the friction between sheets is minuscule under certain circumstances. Kawai et al.

Torque and Twist against Superlubricity
Physical Review Letters, 2008 Superlubricity between incommensurate surfaces provides a desired low-friction state essential for the function of small-scale machines. Here we demonstrate experimentally and theoretically that superlubricity in contacts lubricated by lamellar solids might be eliminated due to torque-induced reorientation coupled to lateral motion.

Editorial: Superlubricity across the scales. [PDF]
Front Chem, 2022 Article talks about how while the idea of frictionless surfaces and the associated implications of vanishing energy losses during mechanical motion have been part of science fiction culture, scientists in the real world work toward realizing this ambitious goal that was once thought to be unattainable.

Impact of Static Distortion Waves on Superlubricity. [PDF]
ACS Omega, 2023 Friction is a major source of energy loss in mechanical devices. This energy loss may be minimized by creating interfaces with extremely reduced friction, i.e. superlubricity. Conventional wisdom holds that incommensurate interface structures facilitate superlubricity.
