Effects of a Constant Magnetic Field on the Electrochemical Reactions of Quercetin

ChemistryOpen, Volume 9, Issue 12, Page 1229-1235, December 2020., 2020
The effect of a constant magnetic field on the processes of quercetin electrochemical reactions has been investigated. Using cyclic voltammetry and impedance spectroscopy, it was found that a constant magnetic field improves the reaction efficiency at the stage in which the oxidation of the OH groups in the A‐ring is the most difficult. For comparison,
