TiO2 modified polyester photocatalysts were prepared by immersion. drying and curing of the polyester in TiO2 containing suspensions under different experimental conditions. The structure of TiO2 layers on the polyester varied according to the time of imme ...
The retinal pigment epithelium (RPE) is constantly exposed to external injuries which lead to degeneration, dysfunction or loss of RPE cells. The balance between RPE cells death and proliferation may be responsible for several diseases of the underlying re ...
Melanocytes respond to UVR not only by producing melanin, but also by proliferating. This is essentially a protective response. We have studied the melanocyte proliferative response after a single UVR exposure to neonatal mice. At 3 days post-UVR in wild-t ...
Hybrid density functional calculations are used to model substitutional lithium (LiZn) and interstitial lithium (Lii) defects in ZnO. The calculated transition levels and formation energies are compared to those obtained using a semilocal density functiona ...
Abstract: Pathogens in sunlit surface waters can be damaged directly by UVB light. Indirect inactivation by reactive oxygen species (ROS) generated by sunlight interacting with external sensitizer molecules may also be important, but this mechanism has not ...
Gas barrier coatings based on single or multiple layers of metals, oxides or nitrides are widely used on polymer substrates in applications ranging from food packaging to organic displays and solar cells. These coatings exhibit a residual permeability resu ...
The importance of the photocatalytic treatment of water is continuously growing since the 80s. In spite of the well management of the existing biological water treatment plants and the constant reinforcement of the wastewater discharge standards, the devel ...
Thirteen different commercial TiO2 powders with specific surface areas varying from 9 to 335 m/g and with isoelectric points (IEP) from 3 to 7.5 were investigated for their catalytic activity in E. coli inactivation. The TiO2 samples zeta potential, attenu ...
