Journal ArticleDOI
Nano-MgO reinforced chitosan nanocomposites for high performance packaging applications with improved mechanical, thermal and barrier properties.
R. T. De Silva,M.M.M.G.P.G. Mantilaka,S.P. Ratnayake,Gehan A. J. Amaratunga,K.M. Nalin de Silva +4 more
TL;DR: Chitosan nanocomposite thin films fabricated by incorporating MgO nanoparticles to significantly improve its physical properties for potential packaging applications displayed remarkable thermal stability, flame retardant properties, UV shielding and moisture barrier properties, which could certainly add value to the packaging material.
Journal ArticleDOI
Magnesium Oxide Nanoparticles Reinforced Electrospun Alginate-Based Nanofibrous Scaffolds with Improved Physical Properties.
R. T. De Silva,M.M.M.G.P.G. Mantilaka,Kheng Lim Goh,S.P. Ratnayake,Gehan A. J. Amaratunga,K.M. Nalin de Silva +5 more
TL;DR: These novel alginate-based/MgO scaffolds are economical and versatile and may be further optimised for use as extracellular matrix substitutes for repair and regeneration of tissues.
Journal ArticleDOI

M. M. M. G. Prasanga Gayanath Mantilaka,Rangika Thilan De Silva,S.P. Ratnayake,Gehan A. J. Amaratunga,K.M. Nalin de Silva +4 more
TL;DR: One dimensional MgO nanofibres with high photocatalytic activity were fabricated using the electrospinning method via a polyvinyl alcohol (PVA)/magnesium precursor based system.
Journal ArticleDOI
Carbon quantum dots-decorated nano-zirconia: A highly efficient photocatalyst
S.P. Ratnayake,M.M.M.G.P.G. Mantilaka,Chanaka Sandaruwan,Damayanthi Dahanayake,Eagambaram Murugan,Santhosh Kumar,Gehan A. J. Amaratunga,Gehan A. J. Amaratunga,K.M. Nalin de Silva +8 more
TL;DR: A unique and efficient composite material was synthesized by incorporating carbon quantum dots on to the surface of zirconia (ZrO2) nanoparticles as discussed by the authors, which showed promise as a formidable contender for industrial dye removal from waste water.
Journal ArticleDOI
Improved nanocomposite of montmorillonite and hydroxyapatite for defluoridation of water
M. Shanika Fernando,A. K. D. V. K. Wimalasiri,S.P. Ratnayake,J. M. A. R. B. Jayasinghe,Gareth R. William,D.P. Dissanayake,K.M. Nalin de Silva,Rohini M. de Silva +7 more
TL;DR: In this article, a novel nano hydroxyapatite montmorillonite (HAP-MMT) nanocomposite system was synthesized using a simple wet chemical in situ precipitation method, and the characterization of the materials was carried out using Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), X-ray diffraction (XRD), and Brunauer-Emmett-Teller (BET) isotherms to study the functional groups, morphology, crystallinity and the surface area
