  • Deflourination of drinking water using layered double Hydroxides 
    Warsakoon, E; Gunawardene, N; Kalahe, H; Munaweera, I; Madusanka, N; Kottegoda, N [Conference-Full-text]
    Safe drinking water is one of the prerequisites for a healthy life. In Sri Lanka 70% of the population satisfy their water needs from ground water and as a result majority of them suffer from water related problems. One ...
  • Nanotechnology in a world out of balance 
    Karunaratne, V; Kottegoda, N; De Alwis, AAP [Article-Abstract]
    As the world population marches towards the 9 billion mark by 2050, factors critical for the sustenance of the ecosystems will come under increasing stress. Having crossed the 7 billion figure in 2011, the 9 billion mark ...

    The fabrication of flexible multilayer graphene oxide (GO) CARBONNANOTUBe membrane and carbon nanotubes (CNTs) using a rare form of high-purity cswcmt^mwcnt, natural graphite, vein graphite, is reported for the first ...
  • Synthesis of magnetite nanoparticles by top-down approach from a high purity ore 
    Priyadarshana, G; Kottegoda, N; Senaratne, A; De Alwis, AAP; Karunaratne, V [Article-Abstract]
    This study attempts to synthesize magnetite nanoparticles from a high purity natural iron oxide ore found in Panvila, Sri Lanka, following a novel top-down approach. Powder X-Ray diffraction, elemental analysis, and chemical ...
  • Urea–hydroxyapatite-montmorillonite nanohybrid composites as slow release nitrogen compositions 
    Madusanka, N; Sandaruwan, C; Kottegoda, N; Sirisena, D; Munaweera, I; De Alwis, A; Karunaratne, V; Amaratunga, GAJ [Article-Full-text]
    Nanohybrid composite was developed by the encapsulation of urea modified hydroxyapatite nanoparticles into the nanolayers of montmorillonite. The nanohybrid composites were synthesized by two approaches; solution phase ...
