For the synthesis of TiO2 powder, the starting material was Ti-butoxide and H2O and the reaction was carried out at 80 oC in a sol-gel method.
TiO2 with a rutile phase has been widely used for white pigment materials because of its good scattering effect that protects materials from ultraviolet light.
Experimental For the synthesis of TiO2 powder, starting materials taken were Ti-butoxide (SIGMA-ALDRICH, reagent grade, 97%, German), ethyl alcohol as a solvent, and the mixture were kept in the water bath (BUCHI, B-480).

The design and construction of the SODIS system require transparent materials that allow sunlight to penetrate through its surface layer to decontaminate water from pathogens.
However, not all transparent materials have suitable properties for SODIS construction because solar water disinfection systems operate in sunny weather conditions that can quickly degrade non-UV-resistant materials.
Each SODIS reactor was made with the following materials; (a) 45o angled two-dimensional 0.5 mm thick highly reflective CPC mirrors were built from aluminium sheets to concentrate solar UV radiation and distribute it equally on the SODIS tube.
Cement, aggregate, binding wire, river sand, and formwork (blockboard, 2x2 timbers, wire nails, and used oil) were critical construction materials for building the plinths at both sites.
The fencing materials for both sites were 75 mm corner posts, 40 mm diamond mesh, razor wire, cutting disc, red oxide, welding rods, 4 mm galvanised wire, and 1 mm galvanised wire.

Introduction Basic task of metal science is to determine optimum composition and method to produce materials with the preset properties.
High cost of solid superconductors is their main disadvantage; thus, new materials are under the development.
Progress of material science of superconductors is connected with the increased critical material characteristics by means of integrated alloying as well as thermal and chemical processing of composite materials.
