(NO3)2+4NaOH +5H2O2=2Co(OH)3+2O2+4H2O +4NaNO3. Enter the amount of any of the substances to determine the ideal amounts to maximize the theoretical yield of the reaction. To find the limiting and excess reagents when a non-ideal amount of each s...
Our work is a step toward final reduction of the mechanism of the studied system to the "minimum oscillator," the concept used earlier, e.g., for the Belousov–Zhabotinsky reaction, of however remarkably different kinetic mechanism.doi:10.1002/kin.20940Albin...
allows plants to maintain H2O2, lignin and phytoalexin at optimized levels to effectively fight against pathogens and prevents these three molecules from over-accumulation that harms plants. Thus, our discovery reveals a novel mechanism by which a single protein promotes two independent defense pathways...
Fig. 1: Electron transfer mechanism at the solid-liquid interface and H2O2 generation. a During the water flow process, chemical reactions and energy transfer occur at the solid-liquid (S/L) interface. b The circulation of water flow promotes interfacial chemical reactions, resulting in the accum...
Notably, the TTN obtained in this study is higher than all reported values for rAaeUPO-catalyzed reaction in bioelectrochemical systems, to the best of our knowledge. Furthermore, in order to gain a comprehensive understanding of the inactivation mechanism in different H2O2-dependent enzymes, the ...
H2O2is toxic to cells due to the creation of hydroxyl radicals by the Fenton reaction. Hydroxyl radicals cause DNA damage, lipid peroxidation, and the formation of unfolded/aggregated proteins, all of which inhibit cell proliferation and can induce cell death6,7. Thus, H2O2levels must be tightly...
2. Mechanism of the oxygen reduction reaction The mechanism of electrochemical ORR is outlined in Fig. 2a. Generally, the ORR involves either a four-electron transfer pathway, which reduces O2 to H2O (Eq. (5)) and is attractive for fuel cells, or a two-electron pathway to produce H2O2 (...
