    The rising demand to increase fresh food shelf life as well as the need of protection against foodborne diseases urged the development of antimicrobial food packaging. Nanomaterials have increasingly being used in food ...
  • Pathirage, TG; Munasinghe, DKR; Udayakumara, SV [Conference-Abstract]
    In Sri Lanka used papers are re-utilized only for paper and board industry. However ,collecting used papers and recycling them are still highly inhomogeneous. Therefore major part of used papers become garbage. Used ...
  • Dilshan, HADI; Weerasinghe, WDD; Attygalle, D [Conference-Abstract]
    The two semiconductor layers Cu2ZnSnS4 (CZTS) and CdS were successfully fabricated using economical, solution-based fabrication techniques. CZTS thin film fabrication was done by spin coating technique onto soda-lime ...
  • Udaraka, MPSD; Nanayakkara, HATV; Attygalle, D; Amarasinghe, DAS [Conference-Abstract]
    Gas sensors are chemical sensors which have a transducer and an active layer for converting the chemical information into another form of electronic signal. Gas detection and determining the composition of a gas in a ...
  • Kumara, PKSP; Dharshana, WMTS; Udayakumara, SV [Conference-Abstract]
    In modern world, fiber reinforced plastics play a dominant role. The fiber which serves as a reinforcement in composite may be synthetic or natural. Although synthetic fibers (ex. Glass, carbon, etc..) posses higher ...
  • Gunerathne, MGGM; Karunasena, DBTK; Attygalle, D; Amarasinghe, DAS [Conference-Abstract]
