Item Characterization of some selected compost samples for the presence of microplastics and heavy metals associated with them(Institute of Chemistry Ceylon, 2021-06-01) Atugoda,Thilakshani; Piyumalia, Hansika; Vithanage,MeththikaMicroplastics are ubiquitous in terrestrial environments as land-based sources mainly contribute to their origin. Mismanagement of solid waste can contribute to heavy loads of microplastics, which is of serious concern in Sri LankaItem Invasive plant-derived biochar for sorptive removal of hexavalent chromium in aqueous media(Institute of Chemistry Ceylon, 2021-06) Ekanayake,Anusha; Rajapaksha,Anushka. U; Vithanage,MeththikaDue to increased industrialization and urbanization, chromium (Cr) has been commonly used and released to the environment in a variety of industrial activities. Two primarily available valence states of chromium in the environment are trivalent chromium (Cr III) and hexavalent chromium (Cr VI). Cr(VI) is more soluble in water, causing health hazards to human beings and animals by all exposure rootsItem Synthesis and characterization of platinum complexes with ethylenediamine and diethylenetriamine sulphonamide ligands towards biological applications(Institute of Chemistry Ceylon, 2021-06) Hettige , L; Perera,I.C; Perera,N.TDiethylenetriamine and ethylenediamine are renowned tridentate and bidentate chelating ligands, and have been utilized to synthesize sulfonamide derivatized platinum complexes.Item Synthesis of Precursors of Cycloparaphenylenes Using Ullmann Coupling(Institute of Chemistry Ceylon, 2021-06) Edirisinghe,Lashan. G; Fernando,Isurika. R[n]Cycloparaphenylenes ([n]CPPs) are carbon and hydrogen containing macrocycles which constitute of ‘n’ number of para-phenylene groups connected via 1,4-biphenyl ‒C‒C‒ linkages.Item Highly Efficient Hydrogen Evolution and Hydrazine Oxidation of Platinum via Tuning the Interfacial Dissolved-Gas Concentration(Institute of Chemistry Ceylon, 2021-06) Ranaweera,RuchirangaRegulating the dissolved-gas concentration at the electrode solution interface represents a promising universal strategy to achieve high efficiency towards gas evolution reactions. Here,Item Semisynthetic derivatization studies of the fungal metabolite phomasetin with activity against the human parasite Trichomonas vaginalis(Institute of Chemistry Ceylon, 2021-06) Peramuna,ThilinaTrichomonasis is the most prevalent sexually transmitted parasitic disease (STD) in the United States and is caused by Trichomonas vaginalis.Item Optimization of Proteomics-based Substrate Trapping with Histone Deacetylase 1(Institute of Chemistry Ceylon, 2021-06) Herath, Kavinda E; Pflum,Mary Kay. HHistone writers and erasures – the proteins that add or remove histone post translational modifications – are key drivers of epigenetic transcriptional events inside the cell.Item Sustainable production of nanomaterials and their activities(Institute of Chemistry Ceylon, 2022-06) Thiripuranathar,GobikaAgriculture is the mainstay of the livelihoods of Sri Lankans. Over the years, the horticulture sector, which includes fruits and vegetables, has gained significant importance and is identified as one of the major contributors to the agriculture sectorItem Improving the Stability of XLAsp-P2 Through Nano conjugation(Institute of Chemistry Ceylon, 2022-06) Amarasekara,Yasuri D.EAntimicrobial (AMP) and Anti-cancer peptides (ACPs) recently have received significant attention as promising chemotherapeutic agents that avoid the drawbacks of current drugs.Item Determination of the solute descriptors for ethyl cinnamate by gas chromatography and liquid-liquid partition systems(Institute of Chemistry Ceylon, 2021-06) Hewage,K. P; Ariyasena,J. A. T. CEthyl cinnamate is a naturally occurring ester found in cinnamon oil extracts. Due to its fruity and balsamic odor, it is used in the preparation of artificial flavours of strawberry, raspberry and cherry and used in oriental oil perfumes.
