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.

Transfer film formation mechanism and tribochemistry evolution of a low-wear polyimide/mesoporous silica nanocomposite in dry sliding against bearing steel [PDF]

, 2018
The addition of a kind of mesoporous silica (MPS) can significantly reduce the wear rate of a thermoplastic polyimide (PI) by more than 90%, which is ascribed to the quick formation of high-quality transfer films induced by unique tribochemical reactions
