The influences of nanoscale titanium dioxide particle size and crystal structure on light absorbance
Nanoscale titanium dioxide is an important physical sun-block material and is widely used in sunscreen. In our test, the influences of the particle size and crystal structure on light absorbance were examined. The experiment shows that the absorbance (Abs) of nanoscale titanium dioxide in UV-ray district is much higher than it in visible light district under the same concentration (0.04 g/L). T...
Introduction: The Phoenix Mars Lander 2007 mission will carry three identical calibration targets to verify and validate the preflight calibration of the Surface Stereo Imager (SSI) and to monitor the stability of this calibration during the mission. The specially designed calibration targets (‘the caltargets’) are at least in one respect more advanced than calibration targets on earlier missio...
Sunscreen products often contain combinations of ultraviolet (UV)-filters in order to achieve broad spectrum protection from exposure to sunlight. The inclusion of both chemical and physical UV-filters in these products, however, increases the possibility for both photolytic and photocatalytic reactions to occur. This study investigated the effect of titanium dioxide (TiO2) particle size on the...
