Better Together: Photoredox/Copper Dual Catalysis in Atom Transfer Radical Polymerization
Angewandte Chemie, Volume 137, Issue 2, January 10, 2025.A combination of Cu‐ATRP catalysis with photocatalysts (PCs) that absorb visible and/or NIR light exhibits synergistic action at the ppm/ppb concentration level. It leads to very well‐defined polymers with rates depending on the amount and quantum efficiency of PC but controlled polymer architecture defined by the Cu‐catalysts.

Advanced Materials Interfaces, Volume 13, Issue 14, 21 July 2026.This study investigates friction and wear of AISI 52100 steel under dry sliding in CO2, air, and N2 atmospheres, with and without contact electrification. CO2 forms a stable carbon‐rich tribofilm that reduces friction by ∼30% and wear by ∼85%. High‐resolution TEM, EELS, and molecular dynamics reveal pressure‐dependent lubrication mechanisms, showing ...
