The mesoporous semiconductor TiO2 microspheres were enriched with gadolinium to be useful in optical imaging and magnetic resonance, due to effects of spin relaxation and photoluminescence. Additional use is due to formation of reactive oxygen compounds. It is essential that cancer cells have different dynamics of internalization of TiO2 microspheres comparing to normal cells. Cancer cells uptake them more efficiently, which is then fatal for cancer cells after exposure to UV light.
By using anodization method we formed membranes composed of titanium dioxide nanotubes. We observed flux of compound AO7 through the membrane. We found that the flux depends on electrical and wetting conditions of the system.
An electric double layer forms when the small mobile ions of an electrolyte interact with an extended charged object, a macroion.. The present work focuses on approaches that instead of going beyond the mean-field character of Poisson-Boltzmann theory introduce structural details of the ions and the solvent into the Poisson-Boltzmann modeling framework.
In the present study, the comparison of pH and UV stability of avobenzone's chlorinated products was studied and presented. The transformation products have been identified by GC-MS. The results indicate, that the dichloro-avobenzone is the most susceptible to photolysis, photo-catalysis and hydrolysis, compared to others. The chloro-avobenzone is as persistent in the environment as its parent compound.
The study presents a novel decentralized sanitary separation system as a zero-discharge solution for blackwater (BW) treatment for remote tourist facilities located in sensitive areas. The important treatment phase was to reach a sanitizing temperature of )60 °C to prevent the release of human pathogens into environment. With a total electricity consumption of 9.1 kWh/day and a heat consumption of approximately 5.1 kWh/day gained by the solar vacuum collectors, the system successfully integrated different approaches to treating the BW, recycling nutrients, and removing pathogens.
