Photostabilization of functional polymeric materials is important for protection against aging and ultraviolet (UV) irradiation. There is, therefore, the impetus to modify polymers increase their resistance photodegradation photooxidation on extended exposure UV light in harsh conditions. Various additives have been designed synthesized recent years, potential as photostabilizers has explored. ...

A major issue in the industrial sector is highly efficient and economical treatment of hazardous dye-based colour effluents. Spinel ferrite nanoparticles are more prominent for their unique qualities, such as optical, catalytic, electrical, magnetic properties. Moreover, physical characteristics ferrites may be influenced well catalytic properties by substituting metals like magnesium. In this ...

Abstract The band-gap energy of TiO2 nanoparticles has been modified using different methods. study reviewed the effects doping and co-doing nanotubes with metals nonmetals to modify its band gap improves photocatalytic activity nanoparticles. From our findings reviewing articles, dissimilar metal ions like Cerium (Ce) together nitrogen (N) or chromium (Cr) iron (Fe) will decrease particle size...

ess as: P r visibl niversity 2013.11.0 Abstract In this study, laponite and montmorillonite clays were found to be able to decompose rhodamine B upon visible light irradiation (k > 420 nm). Very interestingly, it was found that rhodamine B on laponite underwent a stepwise N-deethylation and its decomposition was terminated once rhodamine 110, as a decomposition product, was formed, whereas the ...
