Electrochemical synthesis of peroxomonophosphate using boron-doped diamond anodes [PDF]

, 2008
A new method for the synthesis of peroxomonophosphate, based on the use of boron-doped diamond electrodes, is described. The amount of oxidant electrogenerated depends on the characteristics of the supporting media (pH and solute concentration) and on ...

Mitochondrial toxins potentiate hydroxyl radical production in rat striatum during carbon monoxide poisoning

Journal of Pharmacological Sciences, 2021
Hydroxyl radical (•OH) production in the rat striatum during carbon monoxide (CO) poisoning, which inhibits complex IV, was enhanced synergistically by malonate, a mitochondrial complex II inhibitor, but not N-methyl-4-phenylpyridinium or NaCN, complex I

Hydroxyl radical production in DC streamer discharge [PDF]

, 2015
Plasma-induced advanced oxidation processes do not suffer from the drawbacks, such as carcinogenic by-products, associated with conventional water treatment, and enable the removal of micro-pollutants.
