The high amount of oxygen on the surface induced ROS release in ZnO suspension.
La1−xSrxMnO3 shows an excellent photocatalytic properties in generating high amount of oxygen, were characterized and reported.
A higher amount of oxygen vacancy increases the chance of allowing excited nitrogen to dope onto surface of TiO2 particle.
Coal with a higher amount of oxygen surface groups, and consequently with a less hydrophobic character, had lower methane adsorption capacity.
In addition to the enhancement of internalization, it has been suggested regarding the contribution of the polar facets of ZnO nanostructured to the antibacterial activity, that the higher number of polar surfaces possess higher amount of oxygen vacancies.
Oxygen annealing stimulated a high amount of oxygen atoms to be absorbed onto ZnO surface, thereby enhanced antibacterial response inducing more ROS in the suspension resulting in intense oxidative stress towards the bacteria.
There was low content of dissolved oxygen in water samples from site S1 whereas significantly higher amount of oxygen was available in the water at rest of the sampling sites.
These changes in the infrared spectra were attributed to a higher amount of oxygen atoms that substitute hydrogen atoms at the edges of aromatic clusters of the ethylene/DMF soot particles.
A higher amount of oxygen functional groups was introduced on the material surface by using HNO3 than by means of H2O2, but the original surface texture and structural arrangement were kept unchanged in both cases.
A significantly higher amount of oxygen species compared to conventional wet HNO3 treatment was detected by X-ray photoelectron spectroscopy, and the morphology and the degree of agglomeration did not deteriorate because of the treatment.
