Estimation of Mechanical Properties of Copper Powder Filled Linear Low-Density Polyethylene Composites
Published 2022“…The input parameters manipulated for the prediction were elongation at break (δ), stress at break (ρ), Young’s modulus (Y), volume fraction of the filler (ϕ) and constants (KE1,KE2,KS1,KS2,KS3,KS4,KY1). Copper powder filled LLDPE has a complex structure which makes it difficult to accurately predict the mechanical properties. …”

Novel electroless deposited corrosion — resistant and anti-bacterial NiP–TiNi nanocomposite coatings
Published 2019“…The addition of TiNi nanoparticles into the NiP matrix leads to the transformation of the amorphous structure of the as-plated NiP into a semi-crystalline one. The microhardness of the composite coating significantly enhances with increasing the TiNi concentration up to 0.4 g L−1 and further improvement takes place after the heat treatment. …”
