After thein vitrocultures of nMgO with the bacteria or yeasts for 24 hours, all the cultures showed increasing broth pH and Mg2+ion concentrations due to dissociation of nMgO. The effects of elevated pH or Mg2+ion concentrations on the viability of bacteria was studied usingS. epidermidisas...
The X-rays were generated from a Co source (Kα1 = 0.178897 nm) and filtered with a Ni filter. The measurements were carried out using a step size of 0.018°, a time per scan of 0.02 s within a 2θ range of 20–120°, giving a total analysis time of 35 min. Before the N2 ...
These ions react with electrolyte constituents by the formation of insoluble, electrical isolating compounds and forming dense anodic barrier layer. In the context of PEO treatment, the process is called passivation. This so-called passive layer has a high electrical resistance, which causes a ...
and concentration of the aluminum source. The relationship between the parameters and corrosion resistance performance of each coating was compared with the chemical composition, electrochemical corrosion current, and hydrogen evolution rate. Suitable reaction parameters were obtained. The morphology, element ...
