Photocatalytic Applications

High surface area TiO2 layers are particularly attractive for photocatalytic applications; suitable anodising processes can be used to produce the oxides and to tune their morphology and structure. In the presented research, an alternative technique to enhance the surface area of anodic oxides was identified. This was achieved with the implementation of an anodising treatment performed by supplying alternating current in diluted hydrochloric acid (feeding voltage ranging from 5 V to 10 V). Alternating current anodising caused the formation of a double texture of pits on the oxide surface, the bigger ones being some micrometres wide and formed by smaller pits hundreds of nanometres large; these holes distribution and dimensions can be modulated by varying electrolyte concentration, feeding voltage and anodising time.

To increase the performance of photochemical fuel cells, nonequilibrium electrodeposition has been performed on Cu and Ni to make photosensitive anodes. Processing parameters including electrolyte concentration, and electrode potential were studied using cyclic voltammetry. Scanning electron microscopy (SEM) and X-ray Spectroscopy (EDS) were performed to understand the formation of the nanostructures during the nonequilibrium deposition of copper fractals. An increase in the deposition rate was observed with the increase in electrolyte concentration (from 0.05 M to 1.0 M). Similar trend was found when the cathode potential was decreased from −0.5 V to −4.5 V. The effect of substrate material was also examined. Porous fractal structures on copper were achieved, while the deposited material showed high density of surface cracks on nickel. The fractal structures deposited on copper electrode with the increased surface area were converted into copper oxide by oxidation in air. Such oxide samples were made into anodes for photochemical fuel cell application. We demonstrated that an increase in the magnitude of open circuit output voltage is associated with the increase in the fractal surface area under the ultraviolet irradiation test conditions. However, the electrodeposited fractals on nickel showed very limited increase in the magnitude of open circuit voltage.

A statistically significant eosinopenia occurred on days on which jet aircraft were flown in the mornings. The difference between experimental and control days was more marked in the early part of the afternoon than in the later part. The absolute values for urinary corticoid excretion were not shown to be significantly different on experimental days by comparison with control days, but when expressed in terms of corticoid excretion/body surface area they were seen to be significantly greater on the mornings of experimental days by comparison with control days. Corticoid/body surface area was not constant for different individuals. Salivary electrolyte concentration did not differ significantly on experimental days as compared with control days, but the late afternoon hour at which the single specimen was collected may have missed any change occurring earlier.
