Here a Ga-N5 atomic site on macroporous inverse-opal-type carbon nitride (CNIO-GaSA) is designed and synthesized for visible-light-driven direct photosynthesis of hydrogen peroxide from molecular oxygen and water. The conversion of oxygen and water into hydrogen peroxide was found to occur via a...
METHOD FOR A WASTE WATER TREATMENT PLANT An electroflotation or electroflocculation method using a system for supplying compressed air, ozone and hydrogen peroxide in a reactor having iron, aluminium and/or graphite electrodes. According to the method, a water/sludge mixture fl... BEAUJEAN HOLGER ...
A sequential four-step chemical model for the water oxidation process in photosystem II is presented, based on the observation that a peroxide-linked biquinone complex can be chemically formed as a result of hydroxide ion addition to quinone. In our model, the hydroxide ion intermediate is genera...
Hydrogen peroxide as a solvent will be considered together with water, due to the low acidity and different method of action compared to the other solvents. H2O2is slightly acidic but it will act in different ways depending on the pH of the solution (Aydogan, 2006). It is frequently used ...
Nitric Oxide Reduces Hydrogen Peroxide Accumulation Involved in Water Stress-induced Subcellular Anti-oxidant Defense in Maize Plants Nitric oxide (NO) is a bioactive molecule involved in many biological events, and has been reported as pro-oxidant as well as anti-oxidant in plants. In th... Jia...
content of endogenous hydrogen peroxide (H2O2) and antioxidant enzyme system (Catalase (CAT), Ascorbate peroxidase (APX), Total peroxidase (POD) and Polyphenoloxidase (PPO) were measured in control (100% relative humidity (RH) at field capacity (FC)) and water-stressed plants (50 and 25% RH...
Biosynthesis of lignin in plant begins with the oxidative coupling of three monolignols as a building block of coniferyl, sinapyl, and p-coumaryl alcohols via phenylpropanoid pathway and the last step of lignification is the polymerization of cinnamyl alcohols by POD and using hydrogen peroxide as ...
