  • Photocatalytic activity of nano-tio2 on glass in building envelope 
    Fernando, KDG; De Alwis, AAP; Karunaratne, V; Premaratne, WAPJ [Conference-Full-text]
    Titanium dioxide is manufactured by processing naturally occurring titanium containing rutile (TiO2) or ilmenite (FeTiO3) minerals. Sri Lanka has vast deposits of ilmenite which is the major raw material in TiO2 production. ...
  • Synthesis of Nanosilica from paddy husk ash and their surface functionalization 
    Premaratne, WAPJ; Priyadarshana, WMGI; Gunawardena, SHP; De Alwis, AAP [Article-Abstract]
    Nanosilica was synthesized by a chemical precipitation process from paddy husk ash (PHA) efficiently and effectively. Surface functionalization of the silica nanoparticles was carried out with oleic acid (C18H34O2). Scanning ...
