In the preparative redox chemistry practice, the most commonly used oxidizing and reducing compounds are those whose redox potential is rather inside a limited and accessible solvent-electrolyte electroactivity window. In this framework, a wide variety of neutral, anionic and cationic species can be ...
The reaction was allowed to warm to room temperature and left to react for 4 h. The solvent was removed in vacuo and the residue dissolved in DCM. The organic phase was washed 3 times with water, dried with magnesium sulfate and removed in vacuo. The remaining oil was purified by ...
bipolar magnetohydrodynamic (MHD) electrode (MHDE) producing twice the amounts of ionic vacancies than a conventional single MHDE, the molar excess heat of the pair annihilation of ionic vacancies, 702 kJ m ol−1 at 10 T on average was obtained in a copper redox reaction. It...
After progesterone release, the cumulus cells promote a high Ca2+ influx into the sperm, with initiation of sperm hyperactivation and acrosome reaction. Human sperm have a nongenomic progesterone receptor which, upon activation, promotes the increase in intracellular Ca2+ level through CatSper ...
When cellular GSH is low, GSSG is reduced back to GSH through a reaction that utilizes NADPH, thereby forming a redox cycle. A deple- tion in GSH or reduced GSH/GSSH ratio leads to OS, implicated in cancer progression. In contrast, elevated GSH levels increase the antioxidant capacity ...
Previous research has shown that aggravation of cell-member LPOs was highly dependent on the reaction of Fe2+ with H2O2 in the tumor to generate hydroxyl free radicals. While, the Fenton reaction is limited by the undesirable tumor microenvironment, such as the unsuitable pH [6,7], H2O2 level...

Our increasing dependence on lithium-ion batteries for energy storage calls for continual improvements in the performance of their positive electrodes, which have so far relied solely on cationic redox of transition-metal ions for driving the electrochem
The TiO2 nanocrystals with diameter of a few nanometres were synthesized through a high-temperature hydrolysis reaction in the presence of a nonionic polymeric capping ligand poly(ethylene glycol)-b- poly(propylene glycol)-b-poly(ethylene glycol) (P123), which binds to the nanocrystal surface and...
1. A method of metal recovery from an aqueous solution comprising reaction of a metal ion with a reduced form of a redox polymer capable of reducing the metal ion and recovering reduced metal ions. 2. The method of claim 1 wherein the metal ion is a toxic waste product. ...
