WebROS generation is the antimicrobial mechanism of nanoparticles, hyperbaric oxygen therapy, medical honey, and photodynamic therapy. In addition, it is an alternative bactericidal mechanism of clinically traditional antibiotics. The development of ROS delivery methods with a desirable selectivity for pathogens without side effects for the host ... WebThe two-electron pathway to form hydrogen peroxide (H 2 O 2) is undesirable for the oxygen reduction reaction (ORR) in iron and nitrogen doped carbon (Fe–N–C) material as it not only lowers the catalytic efficiency but also impairs the catalyst durability.In this study, a relay catalysis pathway is designed to minimize the two-electron selectivity of Fe–N–C catalyst.
WebThe interaction of chemical elements with oxygen is called the oxidation reaction. Examples of equations of reactions are: 4Na + О₂= 2Na₂O, S + О₂ = SO₂. Several complex substances also enter into a reaction with oxygen, forming oxides – the equation of the reaction is: СН₄ + 2О₂= СО₂ + 2Н₂О 2СО + О₂ = 2СО₂.
