At pH 13, where zinc undergoes passivation, the oxygen consumption by zinc is 70–80% of the bulk oxygen concentration. The ORR rate on the surface of zinc passive films (ZnO/Zn(OH) 2 ) is thus significant when compared to that on bare/actively corroding zinc. The influence of the ...

Its physicochemical properties indicate that DMSO is highly associated with forming polymer chains due to the interactions between its sulfur and oxygen atoms. However, the effects of temperature or the presence of proton-donor solvents result in self-dissociation of DMSO. The self-dissociation of ...
Dry air has no action at ambient temperatures but the metal combines with dry oxygen rapidly above 225°C. Zinc reacts with carbon dioxide in the presence of moisture at ordinary temperatures forming a hydrated basic carbonate. The metal, on heating with dry halogen gases, yields zinc halides....
A typical electrically rechargeable zinc–air battery requires an efficient bifunctional air electrode, which reduces oxygen during discharging and evolves oxygen during charging. The performance and life of air electrodes are reduced significantly when they are operated in such a bifunctional mode. Several...
Zinc oxide is a white, powdery compound with the chemical formula ZnO. It is a versatile inorganic compound consisting of zinc and oxygen atoms. This compound occurs naturally as the mineral zincite but is more commonly produced synthetically for various industrial applications. These include industrie...
Zinc oxide, ZnO, is a reactive white pigment prepared by vaporizing metallic zinc at a temperature of about 900°C in the presence of oxygen. As a pigment, ZnO is basic in nature and can react with certain types of acidic paint resins resulting in the formation of a brittle film on dry...
In binding sites Zn2+ can accommodate multiple coordination geometries, but is predominantly found in a distorted tetrahedral conformation, interacting with nitrogen (N), oxygen (O), and sulfur (S) donors from histidine, cysteine, glutamate, or aspartate side chains (Lee and Lim, 2008; Habashi...
