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...
These complexes were structurally characterized, revealing in the case of Zn(II) complexes a distorted square pyramid geometry around the Zn(II) center, in which the oxygen atom of a methanol molecule occupies the apical position. Again, the Zn complex shows the largest hyperpolarizability values ...
This can be attributed to their larger surface-area-to-volume ratio, which enhances binding at various target sites on the microbial cell membrane, leading to disruption of cell integrity, the release of metal ions (Zn2+ and Cu2+) [74], and the generation of reactive oxygen species (ROS)...
The optical density (OD) of the converted dye at 570 nm was measured in an ELISA reader to evaluate both the IC50 value and the viability of Vero cells according to this equation: Cell viability (%) = ((OD treatment) / (OD control)) Χ100. Observation of the effects nanoemulsion ...
with maximum peaks correlating with the presence of zinc and oxygen in the tested sample. The energy-dispersive X-ray (EDX) spectra of the ZnONPs sample exhibited distinct peaks corresponding to zinc and oxygen, with energy levels around 1 eV and 9 eV, respectively [78]. These results showed...
et al. Hepatitis C virus regulates transforming growth factor beta1 production through the generation of reactive oxygen species in a nuclear factor kappaB-dependent manner. Gastroenterology 138, 2509–2518 (2010). 60. Nagamine, T. et al. The possible role of zinc and metallothionein in the ...
Furthermore, ZnO-NPs have the ability to prevent the wasting of GSH through oxidative damage prompted by infections, as previously demonstrated by Dkhil et al.101. It is supposed that the antibacterial activity of these metal oxide particles is attributed to the generation of active oxygen species...
Wan changed the oxygen evolution potential (2.6 V) of ZBRB with the help of high-concentration WIS electrolyte, and introduced oxygen redox process (O2− ↔ O−) into the battery system (Fig. 10(b)). Redox not only provides about 27% of additional capacity, but also increases the ...
9b, c). These investigations classified the oxygen species on InP–OA into two categories: carboxylate and hydroxide as X-type surface ligands and In(P)Ox exclusively visible in Raman scattering. In(P)Ox became invisible in the Raman spectra as the temperature increased to 340 °C, ...
and histology showed no sign of gas formation around Zn and its alloys in this study. Oxygen reduction reaction should be the primary cathodic reaction of zinc in the neutral physiological environment. The dissolved oxygen influences the corrosion of zinc in the pH range from 4 to 12, which ap...
