Discerning the catalytic treatment of cationic dye wastewater in photoreactor comprising ternary (Co/Co)-embedded SnO/ZnFeO composite sensitive toward ultra-violet illumination.

Herein, magnetic (Co/Co)-integrated SnO, SnO/ZnFeO, and ZnFeO composites have been prepared from triply distilled water and 30% of isopropanol in the water medium. The phase evolution, microstructure, and magnetism were investigated successfully and tested for cationic dye wastewater degradation containing Rhodamine 6G and Methylene Blue under ultra-violet irradiation. Composite spheres are attributed to efficient heterojunction interfaces between ZnFeO and SnO semiconductors with the support of (Co/Co) nanoparticles.

Understanding the role of DAF-16 mediated pathway in Caenorhabditis elegans during UV-A mediated photoaging process.

Even though Sun is the major source of energy to all living beings in the universe, continuous and prolonged exposure to sunlight will lead to detrimental effects. Human skin will undergo extrinsic aging, known as photoaging upon prolonged exposure to sunlight which is characterized by wrinkles, dryness, loss of elasticity, and so on. The model nematode Caenorhabditis elegans which is widely used in aging studies, could be used to study photoaging also.
