Origin of superlubricity of diamond-like carbon (DLC)

Friction
Hydrogenated diamond-like carbon (H-DLC) is typically produced as a coating or thin film through plasma-enhanced chemical vapor deposition (PE-CVD). H-DLC is relatively hard and well known to exhibit superlubricity.

Superlubric Brownian Motor

Brownian motors are nanoscale machines that utilize asymmetric physical interactions to generate directed motion in space. The operation mechanism relies on the random motion of nanoscale elements generated by thermal activation. On the other hand, structural superlubricity (SSL) refers to a state of nearly vanishing friction due to structural mismatch

Prospects and Challenges for Achieving Superlubricity in Porous Framework Materials (MOFs/POFs): A Review

Lubricants
Metal–organic frameworks (MOFs) and porous organic frameworks (POFs) have been extensively explored in recent years as lubricant additives for various systems due to their structural designability, pore storage capacity, and tunable surface chemistry ...

Whole course oil-based superlubricity for polyetheretherketone-bearing steel sliding pair by introducing tribocatalytically active dialkyl-dithiophosphoric-modified copper nanoparticles in poly-alpha olefin oil

Friction
At present, achieving oil-based superlubricity depends on lubricating oil viscosity and rubbing pair materials excessively. Therefore, establishing a new route is of scientific significance and application value.

Surface nanofabrication beyond optical diffraction limit: Optical driven assembly enabled by superlubricity

Friction
The optical manipulation of nanoparticles on superlubricity surfaces was investigated. The research revealed that, due to the near-zero static friction and extremely low dynamic friction at superlubricity interfaces, the maximum intensity for controlling
