The purpose of the paper is to obtain a new composite material based on chemically functionalized nanoparticles dispersed in plastomer matrix. The dispersion of the TiO2 hybrid nanoparticles (filler) in a plastomer matrix (polyvinyl chloride-PVC) leads to a high-performance polymeric material with multi-functional, antibacterial, and plastomer-specific processing properties. The materials are suitable for biomedical and food industry applications and will be tested in terms of long-term stability, and antimicrobia...

A new trend in concrete technology is to introduce photocatalytic concrete, also known as a self-cleaning concrete. This technology is based on the addition of TiO2 (titanium dioxide) to concrete mixes. Photocatalytic activity of TiO2 and its hydrophilic properties make it suitable for addition to building materials, particularly in architectural concrete or self-consolidating concrete. When concrete surface is exposed to the sunlight most pollutants are neutralized. In the present study the influence of addition ...

Acid Orange 7 was heterophotolyzed using titanium dioxide, oxygen bubbling, back-flow tubular reactor, polychromatic radiation of high pressure Hg lamp and aqueous sodium bicarbonate, sodium hydroxide or sulfuric acid as solvents. Dependences of reaction rates on Acid Orange 7 concentrations have exhibited either straight-line (for lower initial concentrations) or a convex shape (for higher initial concentrations). Variations in shapes of kinetic curves observed were explained by the effect of decrease in both (i)...
