How to Change the Redox Potential of Guanine?
Due to some important applications of guanine electrode in scientific and technology research such as electro-chemical DNA based biosensors, and a problem of high redox potential of guanine (0.81 V), our research study concentrates on reducing guanine redox potential by substituting Cu, Ag, Au, CH3, C2H5 and Cl on sites of 1, 2 and 9 of guanine. A 5.0% reduction...
متن کاملCollectorless flotation of Chalcocite by controlling redox potential
Using microflotation method, this study explored the collectorless flotation of Chalcocite and its dependence on the redox potential of pulp . Electrochemical studies were performed by cyclic voltammetry in specific potential ranges and at different pH values. The results show that significant floatability of Chalcocite occurs in the specific reducing conditions. By increasing potentials, on t...
متن کاملFermentation and Redox Potential
Redox potential, known as oxidation–reduction or oxidoreduction potential (ORP), not only indicates the reduction and oxidation capacity of the environment but also reflects the metabolic activity of microorganisms. Redox potential can be monitored online and controlled in time for more efficient fermentation operation. This chapter reviews the enzymes that modulate intracellular redox potentia...
متن کاملRedox unbalance modifies neurogenic potential
Reactive oxygen species (ROS), including superoxide anion, hydroxyl radicals and hydrogen peroxide, can be formed endogenously by incomplete reduction of molecular oxygen occurring during mitochondrial oxidative phosphorylation, or by interactions with exogenous sources. The antioxidant defense system, with its major enzymes Catalase, superoxide dismutase (SODs) and glutathione peroxidase (Gpx)...
