  • Effect of annealing on temperature coefficient of resistance of cu-ni foil as strain gauge material 
    Satheekshana, W; Weragoda, SC; Amarasinghe, DAS; Samarasekara, AMPB [Conference-Full-text]
    Near zero Temperature Coefficient of Resistance (TCR) is an increasing concern in the strain gauge manufacturing industry. The purpose of this study is to investigate the connection between the TCR of the Strain Gauge (SG) ...
  • Feasibility assessment of obtaining kinetic parameters for independent simultaneous first- order reactions using friedman isoconversion analysis 
    Panawala, PSS; Kanchana, PK; Amarasinghe, DAS; Attygalle, D; Samarasekara, AMPB; Weragoda, VSC [Conference-Full-text]
    This research investigates the effect of two independent first-order reactions occurring concurrently within a given temperature range. A theoretical simulation-based approach was employed to analyze the influence of ...
  • New strategy for synthesizing catalyst-free hcl-doped polyaniline 
    Dinujaya, N; Narangoda, C; Karunanayake, L; Panawala, PSS; Tissera, I; Samarasekara, AMPB; Amarasinghe, DAS [Conference-Full-text]
    A new low-cost strategy for the catalyst-free synthesis of HCl-doped polyaniline (PANI) was developed. A 50:50 (water/hydrogen peroxide) solution was used as an oxidant and a 1M HCl solution was used as an acidic ...
  • Polyaniline film-based interdigitated capacitive sensor for ammonia gas detection 
    Panawala, PSS; Tissera, I; Dinujaya, N; Amarasinghe, DAS; Narangoda, C; Karunanayake, L; Attygalle, D; Weragoda, VSC; Samarasekara, AMPB [Conference-Full-text]
    In this work, an ammonia gas sensor based on Polyaniline(PANI) was fabricated using a custom made Interdigitated capacitive sensor(IDC-S). PANI films were successfully deposited on the IDC-S using the solution ...
  • Unlocking composite property secrets with sem 
    Mudalige, SP; Sanjeewa, PVGI; Amarasinghe, DAS; Attygalle, D
    In this study, we present a software application designed for the analysis of polymer composites and the prediction of their mechanical properties utilizing scanning electron microscopy (SEM) micrographs. The ...
  • Unveiling the barrier: a simulation study on face mask filtration 
    Panawala, PSS; Mudalige, SP; Amarasinghe, DAS; Attygalle, D; Samarasekara, AMPB; Weragoda, VSC [Conference-Full-text]
    In recent years, there has been significant discussion surrounding fibrous filters, particularly in relation to respiratory masks. Manufacturing fibrous filters involves paying close attention to the sticking coefficient ...
