Hydroxyl radical as an indoor oxidant. [PDF]

Environ Sci Atmos
The hydroxyl radical (OH) is the dominant oxidant in outdoor air. Indoors, its role is secondary to ozone (O3). However, growing evidence indicates that OH contributes more significantly to indoor oxidation chemistry than previously recognized.

Electron transfer drives hydroxyl radical formation in peroxone reactions. [PDF]

Environ Sci Ecotechnol
Ozone is a powerful oxidant widely used in water treatment for the degradation of organic pollutants and removal of colour, odor, and pathogens. In aqueous solution, ozone decomposes to generate hydroxyl radicals through chain reactions that are ...

Single-atom-engineered perovskite enables near-theoretical-rate hydroxyl radical electrogeneration. [PDF]

Nat Commun
Electrochemical advanced oxidation that directly activates O2 through the oxygen reduction reaction (ORR) to generate hydroxyl radicals (•OH) offers a sustainable strategy for degrading persistent organic pollutants.

Effects of the Cytoplasm and Mitochondrial Specific Hydroxyl Radical Scavengers TA293 and mitoTA293 in Bleomycin-Induced Pulmonary Fibrosis Model Mice

Antioxidants, 2021
Lung fibrosis is the primary pathology in idiopathic pulmonary fibrosis and is considered to result from an increase in reactive oxygen species (ROS) levels in alveolar epithelial cells.

Enhance diclofenac removal in wastewater by photocatalyst process combination with hydrogen peroxide

Case Studies in Chemical and Environmental Engineering, 2023
Diclofenac (DCF) is a synthetic, non-steroidal anti-inflammatory drug. It is a persistent chemical that resists biological degradation and is difficult to completely remove by conventional wastewater treatment plants (WWTP).
