It has been shown in the experiment with albino rats that the prolonged influence of stable noise (90 dB) results in a shift of the redox equilibrium in the thiol-disulphide and ascorbate systems of the adrenal gland and myocardium tissues towards oxidation and the activity of glucoso-6-phosphate dehydrogenase and superoxide dismutase decreases. A concept on the pathogenetic role of the redox equilibrium disturbance in the thiol-disulphide system, in particular, in the development of noise pathology is suggested.

Ruthenium dioxide has attracted extensive attention as a promising catalyst for oxygen evolution reaction in acid. However, the over-oxidation of RuO into soluble HRuO species results in a poor durability, which hinders the practical application of RuO in proton exchange membrane water electrolysis. Here, we report a confinement strategy by enriching a high local concentration of in-situ formed HRuO species, which can effectively suppress the RuO degradation by shifting the redox equilibrium away from the RuO over-oxidation, greatly boosting its durability during acidic oxygen evolution.

Hemoglobin and myoglobin are known to undergo autoxidation, in which the oxyferrous form of the heme is oxidized to the ferric state by O. Dehaloperoxidase-A (DHP-A), a multifunctional catalytic hemoglobin from Amphitrite ornata is an exception and is observed to undergo the reverse process, during which the ferric heme is spontaneously reduced to the oxyferrous form under aerobic conditions. The high reduction potential of DHP (+202 mV at pH 7.

Copper-based materials, renowned for their redox versatility and conductivity, have extensive applications in electrochemical sensing. Herein, we construct stable Cu/Cu interfaces within dual-valence copper nanostructures to achieve enhanced sensitivity in glucose sensing. By employing a hydrolysis method to tune Cu/Cu ratios precisely, we achieved an optimal electrochemical interface with heightened stability and reactivity.

Previous studies have predominantly focused on the solidification of oxidized Earth-similar planets, but the diversity in mean density and irradiation observed in the low-mass exoplanet census motivate exploration of strongly varying geochemical scenarios. We aim to explore how variable redox properties alter the duration of magma ocean solidification, the equilibrium thermodynamic state, melt fraction of the mantle, and atmospheric composition.
