  • Biopolymer-Based Nanohydroxyapatite Composites for the Removal of Fluoride, Lead, Cadmium, and Arsenic from Water 
    Fernando, M. Shanika; Wimalasiri, A. K. D. V. K.; Dziemidowicz, Karolina; Williams, Gareth R.; Koswattage, K R; Dasanayake, Dhammike P.; De Silva, K. M. N.; De Silva, R. M. (American Chemical Society, 2021-03-18)
    In this study, hydroxyapatite (HAP) nanocomposites were prepared with chitosan (HAP-CTS), carboxymethyl cellulose (HAP-CMC), alginate (HAP-ALG), and gelatin (HAP-GEL) using a simple wet chemical in situ precipitation method. ...
  • Improved nanocomposite of montmorillonite and hydroxyapatite for defluoridation of water 
    Fernando, M. Shanika; Wimalasiri, A. K. D. V. K.; Jayasinghe, J. M. A. R. B.; Williams, Gareth R.; Dasanayake, Dhammike P.; De Silva, K. M. N.; De Silva, R. M. (Royal society of chemistry, 2019-11-01)
    A novel hydroxyapatite montmorillonite (HAP-MMT) nanocomposite system was synthesized using a simple wet chemical in situ precipitation method. Neat nano hydroxyapatite (HAP) was also synthesized for comparison. The ...
  • Microwave assisted accelerated fluoride adsorption by porous nanohydroxyapatite 
    Wimalasiri, A. K. D. V. K.; Fernando, M. Shanika; Williams, Gareth R.; Dasanayake, Dhammike P.; De Silva, K. M. N.; De Silva, R. M. (Elsevier, 2021-01-01)
    Fluoride pollution of water is a matter of concern in many countries due to its association with chronic kidney failure. Therefore, it is important to develop fast and efficient methods for fluoride removal from drinking ...
  • Multifunctional HAP nanocomposites for antimicrobial activity 
    Fernando, M. Shanika; Wimalasiri, A. K. D. V. K.; Gayashan, M. K.; De Silva, R. M.; De Silva, K. M. N.; Dasanayake, Dhammike P. (University of Colombo, 2020)
    Contamination of water bodies by chemical and biological pollutants has resulted in shortage of clean and safe drinking water all over the world. Hydroxyapatite based nanocomposites have been identified as promising materials ...
  • Structure−Activity Relationship of Lanthanide-Incorporated Nano- Hydroxyapatite for the Adsorption of Fluoride and Lead 
    Wimalasiri, A. K. D. V. K.; Fernando, M. Shanika; Dziemidowicz, Karolina; Williams, Gareth R.; Koswattage, K. R.; Dasanayake, Dhammike P.; De Silva, K. M. N.; De Silva, R. M. (American Chemical Society, 2021-05-17)
    The growing demand for water purification provided the initial momentum to produce lanthanide-incorporated nano-hydroxyapatite (HAP) such as HAP·CeO2, HAP·CeO2·La(OH)3 (2:1), and HAP·CeO2·La(OH)3 (3:2). These materials ...
