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 ...

Riboflavin‐Catalyzed Photoinduced Atom Transfer Radical Polymerization
Macromolecular Chemistry and Physics, Volume 226, Issue 7, April 2025.PhotoATRP of methyl acrylate with riboflavin (RF) and CuBr2/Me6TREN as a dual catalytic system is successfully carried out under a green LED light. The process demonstrated high chain‐end fidelity, efficient oxygen tolerance, and controlled polymerization kinetics, driven primarily by reductive quenching of RF.

Superlubricity and tribochemistry of polyhydric alcohols [PDF]
Physical Review B, 2008 The anomalous low friction of diamondlike carbon coated surfaces lubricated by pure glycerol was observed at 80 °C. Steel surfaces were coated with an ultrahard 1 µm thick hydrogen-free tetrahedral coordinated carbon (ta-C) layer produced by physical vapor deposition.
