Advanced Functional Materials, EarlyView.This study develops a novel atomic engineering strategy to fine‐tune the spin state of α‐Fe2O3 catalysts toward a medium‐spin state, thereby modulating peroxymonosulfate activation and selectively yielding surface‐bound radicals. Compared with free radicals, surface‐bound radicals exhibit moderated oxidation potential, extended lifespan, surface ...

Superoxide anion production and superoxide dismutase and catalase activities in Coxiella burnetii [PDF]
Journal of Bacteriology, 1983 Coxiella burnetii was examined for superoxide anion (O2-) production and superoxide dismutase and catalase activities. The organism generated O2- at pH 4.5 but not at pH 7.4. The rickettsia displayed superoxide dismutase activity distinguishable from that of the host cell (L-929 mouse fibroblast).

Advanced Healthcare Materials, EarlyView.Metallofullerenol Sc3N@C80(OH)18 demonstrates strong radioprotective properties as a scavenger of both short‐ and long‐lived radicals. The study reveals protection of human erythrocytes from γ‐radiation–induced biochemical damage via post‐irradiation removal of primary and secondary reactive oxidants, supported by pulse radiolysis kinetics.
