Abstract Electromagnetic pollution is emerging as one of most dominant pollution in recent times largely due to the widespread use of electronics equipment ranging from the personal use, societal benefits to modern warfare. Also known as electromagnetic smog, this pollution is not only capable to disrupt the existing systems but can also affect the human health adversely. Accordingly, it is becoming important to progress in this area through developing and designing materials and promoting technologies that are superior to the one currently used for shielding electromagnetic waves. The aim of this paper is to introduce readers to electromagnetic radiation threats and the current materials science that is used to mitigate these effects. Go to Introduction Electro smog (e-smog) or electromagnetic pollution has increased tremendously in recent years due to ever increasing use of electronic gadgets. Accordingly, it is not surprising that electromagnetic pollution has emerg...

Material Science-Juniper Publishers Abstract In this study, prepared the nano composites of Co: La:Tio 2  by the wet chemical method. Synthesized Tio 2  and Co:La:Tio 2  were characterized by X-Ray Diffractometer, SEM,TEM, UV-vis, FT-IR, Band gap energy and BET. The Tio 2  and Co:La:Tio 2  were used as photocatalyst for the degradation of Methyl Blue. The XRD pattern confirmed the presence of anatase and rutile phase in the catalyst. The particle size was estimated by the Scherrer’s and found 68 and 32nm for Tio 2  and Co: La: Tio 2  respectively. The particle morphology of the photocatalysts was found in nanodiamension. The surface area of the photocatalysts were found 37.52 and 106.68m2/g for Tio 2  and Co: La.Tio 2  respectively. The band gap energy of Tio 2  and Co: La.Tio 2  were 3.2 and 3.0eV. The photo degradation of Methyl Blue has been found maximum at 5pH, 25ppm concentration of dye, 800mg/L amount of photo catalys...
