We studied the mechanism of the vasodilator effect of H2O2 on cerebral arterioles and its effect on endothelium-dependent responses to acetylcholine. Topical application of H2O2 (0.1-1 microM) on the ...

Hydrogen peroxide (H2O2) functions as both a signalling molecule and a potentially damaging oxidant in plants. At controlled concentrations, it orchestrates stress perception and defence activation by ...

Most studies investigating the influence of H2O2 on cells in culture apply nonphysiological concentrations over nonphysiological time periods (i.e., a one-time bolus that is metabolized in minutes).

Chinese Journal of Catalysis is co-sponsored by Dalian Institute of Chemical Physics, Chinese Academy of Sciences and Chinese Chemical Society, and it is currently published by Elsevier group. This ...

Normal aerobic metabolism (via processes such as photosynthetic and respiratory electron transport chains) in plants yields varied reactive oxygen species (ROS) such as singlet oxygen (1O2), ...

New Approach Developed for Electrocatalytic H2O2 Production and Biomass Upgrading. Credit: Hui Xu Chinese scientists have created a new electrocatalyst with oxygen-coordinated Fe atoms, significantly ...

A study reveals how hydrogen peroxide (H2O2) signaling regulates tomato ripening through the redox modification of RNA demethylase SlALKBH2. This modification stabilizes SlALKBH2, enhancing its role ...

Upon addition of hydrogen peroxide to Rochelle's salt (sodium potassium tartrate), the hydrogen peroxide decomposes and tartaric acid is oxidized. This reaction proceeds very slowly at room ...

From the polyurethane that makes our car seats to the paper made from bleached wood pulp, chlorine can be found in a variety of large-scale manufacturing processes. But while chlorine is good at ...
