Atmospheric cold plasma to improve printability of polyethylene terephthalate

Sandanuwan, T; Hendeniya, N; Attygalle, D; Amarasinghe, DAS; Weragoda, SC; Samarasekara, AMPB [Conference-Full-text]

Though paper is still the most common substrate in the printing industry, polymeric substrates are becoming common by the day. Commercially available polymers such as polyethylene terephthalate (PET), polyvinyl chloride ...
Atmospheric pressure plasma treatment as a cost-effective and eco-friendly pre-treatment method to enhance seed perfomance in germination and early seedling growth

Hendeniya, N; Sandanuwan, T; Amarasinghe, DAS; Attygalle, D; Weragoda, S; Ranaweera, B; Rathnayake, K; Lalanka, M [Conference-Full-text]

Novel methods of improving the seed quality have gained a lot of attention recently, cold atmospheric pressure plasma being one of the most promising methods. The effects of cold atmospheric pressure plasma treatment of ...
Effects of current density on the solder wettability of nickel electrodeposited ni20cr alloy

Kumarasiri, A; Herath, HS; Amarasinghe, DAS; Attygalle, D [Conference-Full-text]

Nickel-chromium alloys are in high demand in the electrical industry, as they have some favorable electrical properties. The formation of a thin chromium oxide layer on the alloy surface protects the alloy from further ...
Individualization of nanofibrillated cellulose from Sri Lankan rice straw: structural characteristics and thermal properties

Ratnakumar, A; Samarasekara, AMPB; Amarasinghe, DAS; Karunanayake, L [Conference-Full-text]

Rice straw is the agricultural production residue which is considered as an agricultural waste. Though it is utilized in various ways, there is a greater possibility for value addition by disintegrating nanofibrillated ...
Linear and non linear creep modeling of talc filled peek composite

Janith, GI; Amarasinghe, DAS; Attygalle, D; Weragoda, VSC; Samarasekara, AMPB [Conference-Full-text]

The creep compliance of a viscoelastic material is a crucial material parameter that controls the time dependent creep. Viscoelastic materials and their composites are being widely used in electronic and structural components ...
Microfibrillated cellulose fabrication and characterization from sri lankan rice straw: a comparison between traditional and hybrid variety

Ratnakumar, A; Samarasekara, AMPB; Amarasinghe, DAS; Karunanayake, L [Conference-Full-text]

Rice is one of the major cereal crops cultivated globally. In the recent past, rice straw has gained momentum as a source of cellulose. However, it is notable that rice straw generated from rice cultivation has less or no ...
Modeling of laser assisted thermal reduction of graphene oxide

Rajapakshe, VS; Warnakulasooriya, WMDS; Amarasinghe, DAS; Attygalle, D [Conference-Full-text]

A computational model to predict the degree of reduction of graphene oxide by using laser irradiation was developed. 3-Dimensional thermal distribution was modeled using heat conduction equation and computational modeling ...
Moisture transportation in polyester fabrics by plasma printed wicking channels

Gunarathna, RNP; Sandanuwan, T; Amarasinghe, DAS; Attygalle, D; Weragoda, SC; Hendeniya, N [Conference-Full-text]

By dissipating the absorbed moisture on clothes quickly, the wearer's comfortability can be improved. Wicking plays a vital role in transporting sweat away through the fabric from the generation areas of the body. Usually, ...
Process optimization of microfibrillated cellulose extraction from cotton waste using response surface methodology

Jayasinghe, JMR; Ratnakumar, A; Samarasekara, AMPB; Amarasinghe, DAS [Conference-Full-text]

Cotton is a natural staple fiber that mostly consists of cellulose compared to wood. The major economic value of cotton is in textile industry. Over the recent past years the demand for cotton consumption has increased ...
