The charge-transfer resistance of the hydroquinone (QH 2), quinone (Q) mercury redox system has been determined in its dependence on the concentration of the redox components. Additionally the adsorption-behaviour at the equilibrium potential had been investigated. The results of the resistance and ...

4d). Noticeably, compared to that in pure water, the solubility of hydroquinone was reduced even further by ~14 times in 20m LiTFSI. The greatly suppressed PAQ solubilization in salt-concentrated electrolytes, together with minimized side reactions, enabled impressive PAQ cycling stability (~90% ...
activity because of the 609C4T or 465C4T polymorphism has been associated with an increased risk of various types of cancer, including GI cancer.7 NQO1 is also known as DT-diaphorase, a cytosolic flavoenzyme that is able to catalyze the two-electron reduction of quinones to hydroquinones. Qu...
Thus, QH2/Q ratios at system equilibrium decreased as either pH values and oxygen concentration (allowing hydroquinones autoxidation) or the amount of laccase increased. Once the cyclic nature of the system was demonstrated, special attention was paid to the production of O-.2 during hydroquinone...
The hydroquinone SAMs were diluted with octane-1-thiol. Cyclic voltammograms of the quinone/hydroquinone (Q/H 2Q) couple allowed the peak-to-peak separation of the anodic and catholic peak potentials to be analyzed and apparent rate constants ( k app) to be determined using Laviron's ...
In agreement with experimental deductions the preferred configuration for the quinone-hydroquinone complex is found to be one in which the molecules are in parallel planes with their C—O bonds parallel. The equilibrium separation between the molecular planes is found to be 2.3 and the stabilization...
