Item Copper-zinc oxide nanohybrids for advanced antimicrobial and photocatalytic applications(Institute of Chemistry Ceylon, 2025-05) Herath,Hasitha; Pasindu Viduranga,T.A.V; Yapa,Piyumika; Munaweera,Imalka; Samarakoon,UpekaZnO exhibits remarkable photocatalytic and antimicrobial activity as a nanomaterial for diverse applications, including environmental remediation, healthcare, and sustainable energy solutions. However, a major problem with ZnO photocatalyst is that it is active only under UV irradiation owing to its high band gap.Item Harnessing the Power of Visible Light with GO-Ni-ZnO Nanohybrid Electrospun Polymeric Membranes for Improved Photocatalysis:(Institute of Chemistry Ceylon, 2025-05) Pasindu ,Viraj; Yapa,Piumika; Dabare,Sanduni; Munaweera,Imalka; Etampawala,Thusitha; Weerasekera,Manjula M; Attygalle,Dinesh; Amarasinghe,ShanthaPhotocatalysis exhibits considerable potential for a range of environmental, energy, and biomedical applications, especially when employing metal-doped nanoparticle systems like Ni-doped ZnO. By giving nanohybrid stability and structural support, graphene oxide (GO) enhances photocatalytic activities and increases its durability and resistance to photo- corrosion.Item Prospects of engineered inorganic nanostructures in multidisciplinary applications(Institute of Chemistry Ceylon, 2023-06) Munaweera,ImalkaConsiderable interest is being exhibited in the novel and enhanced properties of inorganic nanostructured materials. Inorganic particles often exhibit novel physical properties as their size approaches nanometer scale dimensions.
