Radical, Not Ionic: The Mechanochemical Zincke Nitration of Phenols
Angewandte Chemie, EarlyView.Mechanochemistry recasts the classical Zincke nitration as an open‐shell process. Liquid‐assisted vibrational milling of phenols with in situ HNO2 delivers direct and ipso nitration across 50 substrates, while atmosphere, NOx‐transfer, EPR and DFT evidence expose a phenoxyl‐radical/NO2 manifold underlying this historically ionic transformation ...

Photolysis of hexachlorocyclopentadiene in water
Ecotoxicology and Environmental Safety, 1982 Abstract 14 C-Hexachlorocyclopentadiene (hex) (C 5 Cl 6 ) was photolyzed rapidly when dissolved in water and irradiated with a mercury-vapor light source. The photolytic half-life of hex was less than 1.03 min. Pentachlorocyclopentenone was tentatively identified as the primary photolysis product of hex.

Advanced Science, EarlyView.A light‐activated catheter insert combines antimicrobial blue light with nitric oxide release to generate complementary oxidative and nitrosative stress, producing potent broad‐spectrum antimicrobial activity. The approach achieves greater than 4‐log reductions in bacterial and fungal viability and significantly reduces Staphylococcus aureus ...

OH produced from o-nitrophenol photolysis: A combined experimental and theoretical investigation
, 2009 Photodissociation dynamics of o-nitrophenol in the gas phase at different photolysis wavelengths (361-390 nm) is investigated, and the nascent OH radical is observed by the single-photon laser-induced fluorescence technique.

Angewandte Chemie, EarlyView.Time‐resolved in situ x‐ray absorption spectroscopy and DFTB‐based molecular dynamics simulations identify direct hydrogen atom transfer from ethanol to lattice oxygen as the elementary step of laser‐driven reduction in NiCo2O4. While this transfer is facile, the subsequent release of lattice oxygen is entropy‐driven and becomes accessible only at ...
