Superlubricity, a state where friction between two contact surfaces is nearly zero, has a great potential to revolutionize various mechanical systems by significantly reducing energy dissipation and enhancing efficiency. It can be realized either by structural incommensurate contact between crystalline surfaces or by creating highly passive interfaces ...

Advanced Materials Interfaces, Volume 12, Issue 22, November 22, 2025.Friction force microscopy using diamond tips on epitaxial graphene supported by SiC(0001) shows a sharp friction increase. Silicon tips show similar behavior but at lower threshold forces. Atomistic simulations reveal three different friction regimes as normal pressure rises: graphene‐tip interfacial slip, graphene‐tip bonding, and a reversible ...

Structural lubricity: Role of dimension and symmetry
, 2003 When two chemically passivated solids are brought into contact, interfacial interactions between the solids compete with intrabulk elastic forces. The relative importance of these interactions, which are length-scale dependent, will be estimated using ...

Small Structures, Volume 6, Issue 10, October 2025.The functionalization with graphitic nanodiamonds enhances friction reduction in diamond‐like carbon‐based interfaces. It promotes the formation of a stable, highly graphitic transfer layer, maintaining the core–shell arrangement. This study extends recent advances in superlubricity, providing insights into lubrication mechanisms in humid environments ...

Hyomen Kagaku, 2003 Superlubricity, a phenomena of vanishing friction, has been studied theoretically and experimentally. It is theoretically shown that certain unique cases exist where friction force exactly vanishes when the atomic arrangements on the contacting surfaces satisfies the condition for the appearance of superlubricity.

Molecular Dynamics Study on Quartz‐Indenter Shape and Depth Effects in Epoxy Interfacial Mechanics
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 13, Page 2949-2964, September 2025.ABSTRACT The interfacial mechanical behavior between epoxy and quartz at the microscale remains inadequately understood. The quartz‐indenter shape and indentation depth (hc) effect on epoxy interfacial mechanical behavior has been investigated through molecular dynamics (MD) simulation of nanoindentation and nanoscratching.
