Nowadays, concern over skin cancer has been growing more and more, especially in tropical countries where the incidence of UVA/B radiation is higher. The correct use of sunscreen is the most efficient way to prevent the development of this disease. The ingredients of sunscreen can be organic and/or inorganic sun filters. Inorganic filters present s...
The successful function of photovoltaic (PV) and photocatalytic (PC) systems centers primarily on the creation and photophysics of charge separated electron-hole pairs. The pathway leading to separate carriers varies by material; organic materials typically require multiple events to charge separate, whereas inorganic semiconductors can directly pr...

TiO 2 photocatalysis can be used to kill surface adherent bacteria on biomaterials, and is particularly interesting for use with percutaneous implants and devices. Its efficiency and safety, however, depend on the activation energy required. This in vitro study investigates synergetic effects against the clinically relevant strains S. epidermidis a...

The adsorption of CO on reduced, rutile TiO2(110) is investigated using IR reflection-absorption spectroscopy and temperature-programmed desorption. Experiments using s- and p-polarized IR light incident along the [001] and [11̅0] azimuths give detailed information on the adsorption geometry of the CO as a function of the CO coverage, θCO. The resu...

Penetration of titanium dioxide nanoparticles into enterocytes after their administration into isolated loop of rat small intestine was shown in vivo by transmission electron microscopy. Using electron diffraction, titanium dioxide nanoparticles were identified in the apical regions of the cells under plasma membranes and in deeper parts of the cyt...

The luminescent properties of titanium dioxide nanoparticles obtained by laser ablation have been determined. The position of the luminescence peaks is shown to depend on the excitation wavelength. The luminescence peaks are assigned to certain types of defects in the nanoparticles. The effect of annealing in the range 400°C–1000°C on the photolumi...
