Binding interactions of coumarin derivatives with Hodgkin’s disease related protein ADAM-10; an in-silico approach
(Institute of Chemistry Ceylon, 2019-05) Thilakarathne,N.M. H. N; Udawatte,C. S; Rathnaweera,C .N
Hodgkin’s disease is a malignant tumor which is one of the most common cancers among the elderly and children. It is characterized by the overexpression of ADAM-10 protein with increased release of NKG2D ligand which causes impaired immune response against tumor cells.1

Synthesis and characterization of graphene oxide coated silica nanoparticles
(Institute of Chemistry Ceylon, 2019-05) Weerasinghe,M. A .S .N; Liyanage,J .A; Kumarasinghe,A .R
Graphene oxide (GO) is capable of absorbing many common pollutants of water such as heavy metals and organic contaminants. However, graphene oxide membranes easily disintegrate in water and aggregates. T his decreases its adsorption capacity and diminishes its practical applications. Therefore, to prevent the above problems graphene oxide is combined with silica nanoparticles.

Fabrication and characterization of water stable multi-layer graphene oxide membranes by potassium ion crosslinking
(Institute of Chemistry Ceylon, 2019-05) Bandara,W. R. N. M; Liyanage,J. A; Kumarasinghe,A. R
Graphene Oxide (GO) was synthesized from vein graphite sourced from Bogala mine using Improved Hummer’s method. GO nano sheets are the oxidative exfoliation products of graphite. GO contains oxygenated functional groups attached to their basal planes and edges.

DFT study on classical Koshland retention mechanism of Linamarin hydrolysis
(Institute of Chemistry Ceylon, 2019-05) Dinuka,D. L. S; Ratnaweera,C. N
T he hydrolysis of glucosidic linkage catalyzed by every carbohydrate-hydrolase is a reaction in which the product retains (α→α or β→β) or inverts (α→β or β→α) the anomeric configuration of the substrate. By releasing α-glucose and β-glucose, respectively, from the common substrates having α or β -glucosidic linkages, α-glucosidase and β-glucosidase are essentially distinguished.

A study on the use of Bathophenanthroline as a fluorescence sensor for iron(II)
(Institute of Chemistry Ceylon, 2019-05) Perera,P.P.P; De Costa,M D P; Senthilnithy,R
Although Fe2+ is present as a trace element, it plays a vital role in living systems. Therefore measurement of trace amounts of Fe2+ is very important for many biological and ecological studies. Bathophenanthroline (BPhen) forms a stable 1:3 red color complex with Fe2+ and appears as a promising colorimetric probe for Fe2+. Using colorimetry, it has been possible to detect 10 parts of Fe2+ in 109 parts of water (540 nM).1,2
