This work aimed to investigate the influence of selected material variables on self-cleaning and air purification efficiency in NOx pollutants cement-based photocatalytic composites. Tests were performed cement mortars, with seven independent considered: mass ratio between quartz powder sand, water ratio, total amount photocatalysts (two different types), content nanoparticulate silica, percent...

titanium dioxide (tio2)nanoparticles have been frequently employed in the environmental treatment and purification purposes as a cheap and highly efficient photocatalyst. a photocatalyst can facilitate the breakdown and removal of a variety of environmental pollutants at room temperature. tio2 photocatalyst is the best candidatebecause of its strong oxidized ability, non-toxicity and longtherma...

Manganese/TiO2 composites are prepared by a solvothermal process starting from the precursors titanium propoxide and manganese nitrate. The solvothermal processes are driven at temperatures of 140 °C or 180 °C. The formation of anatase as crystalline TiO2-phase was determined by XRD for preparation conditions at 180 °C. The occurance of crystalline phases in nanometer scale is determined furthe...

3 | P a g e Abstract This thesis is concerned with the synthesis and characterisation of TiO2 based photocatalyst thin films and the assessment of their antimicrobial properties. When exposed to light of wavelength less than 380 nm TiO2 films can demonstrate self-cleaning and self-disinfecting properties. This is due to photocatalytic processes occurring on the film surface resulting in film su...

Background: Fear of dental care prevents dental cleaning behavior and increases the prevalence of dental caries. This study was conducted to determine the effect of Trans-Theoretical Model constructs and fear of dental care on the dental cleaning behavior of students. <span style="font-family...
