  • Silica Based Superhydrophobic Nanocoatings for Natural Rubber Surfaces 
    Wimalasiri, V.K.; Weerathunga, H.U.; Kottegoda, N.; Karunaratne, V. (open access article distributed under the Creative Commons Attribution License, 2017-08-08)
    Silica based nonfluorinated superhydrophobic coatings for natural rubber surfaces have been developed. The coating was synthesized using nanosilica dispersion and a polychloroprene type binder as a compatibilizer.This ...
  • Surface Functionalization Of Cellulose Fibers with Calcium Silicate Nanoparticles 
    Priyadarshana, G.; Siriwardhana, A.; Kottegoda, N.; Amaratunga, G.; Karunaratne, V. (2017-09)

  • Urea-Hydroxyapatite Nanohybrids for Slow Release of Nitrogen 
    Kottegoda, N.; Sandaruwan, C.; Priyadarshana, G.; Siriwardhana, A.; Rathnayake, U.A.; Arachchige, D.M.B.; Kumarasinghe, A.R.; Dahanayake, D.; Karunaratne, V.; Amaratunga, G.A.J. (2017 American Chemical Society, 2017-01-25)
    While slow release of chemicals has been widely applied for drug delivery, little work has been done on using this general nanotechnology-based principle for delivering nutrients to crops. In developing countries, the ...
  • Urea-silica nanohybrids with potential applications for slow and precise release of nitrogen 
    de Silva, M.; Siriwardena, D.P.; Sandaruwan, C.; Priyadarshana, G.; Karunaratne, V. (Elsevier, 2020)
    The adoption of nanoparticles as carrier matrices in the production of hybrid functional materials is futuristic in agriculture applications. In this study, a greener, modified in-situ sol-gel route was employed to ...
  • 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, G.A.J. (2018 Elsevier B.V. or its licensors or contributors., 2017-12-15)
    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 ...
