Development of a photosensor based on photo dielectric effect of cadmium sulphide

Kumari, TID; Jayasumana, MASD; Attygalle, D [Conference-Abstract]

A photosensor is an electronic component that detects the presence of visible light, infrared radiation, and/ or ultraviolet radiation. A photosensor which changes its electrical capacitance in the presence of visible ...
Development of graphene oxide based capacitive gas sensor for selective detection of NO2

Gunasena, RGSP; Deemantha, MBA; Amarasinghe, DAS; Attygalle, D [Conference-Abstract]

NO2 gas is a harmful vapor that, when present in large quantities, can impose severe threats on health and environment. Gas sensors for NO2 have been in development over the past few decades albeit selectivity towards ...
Identifying better fitting function for asymmetric differential thermo gravimetric signal analysis

Dodampola, R; Egodage, D; Amarasinghe, S; Attygalle, D; Weragoda, S; Perera, T [Conference-Abstract]

Thermogravimetric analysis is one of the main technique used in solid state reaction kinetics studies. Unlike in gaseous and liquids state reactions, most solid-state reaction mechanisms are complex and comprise of ...
Improvement of toner printing on polyethylene terephthalate based transparency sheets using atmospheric plasma

Sandanuwan, GAT; Somaweera, GD; Attygalle, D; Amarasinghe, DAS; Weragoda, VSC [Conference-Abstract]

The application of atmospheric plasma to improve printability on transparency sheets is presented in this paper. Printing on polymer substrates like Polyethylene, polyethylene terephthalate (PET), Poly propylene have ...
Investigation on self-discharge mechanism of neutral aqueous electrolyte based electric double layer supercapacitor

Gunarathna, RNP; Muhandiram, DI; Attygalle, D; Amarasinghe, DAS [Conference-Abstract]

Supercapacitors are capable of holding electrical charges that are much larger than conventional dielectric capacitors. A supercapacitor was constructed using active carbon electrodes, deposited on metal current collectors ...
Lead free solder compatibility improvement on nichrome alloy through contact angle modification

Kumarasiri, A; Attygalle, D; Amarasinghe, DAS [Conference-Abstract]

Nichrome (Ni/Cr) alloys which are used in many industrial applications are known to have a surface passivation layer of chromium oxide (𝐂𝐫𝟐𝐎𝟑 ). This layer alters the surface tension and thereby decreases the surface ...
