Comparative study of the Magnetoelectric Properties in Core-Shell Nanocomposites as well as mixture of CoFe2O4:BaTiO3
Abstract: Nanostructures of multiferroic materials have been drawing increasing curiosity due to the boosted magnetoelectric coupling and potential for succeeding generation multifunctional devices. Composites of ferroelectric and magnetostrictive materials indicate more magnetoelectric coupling than single phase materials. Core-shell CoFe2O4:BaTiO3 nanocomposites (1:1 weight ratio) and a mixture of both of them have been produced by a combination of hydrothermal and sol gel techniques. X ray diffraction analysis endorses the presence of both …

Prediction of Compressive strength of Periwinkle Shell Aggregate Concrete Using a Quadratic Polynomial Function
Abstract: In this study, a mathematical model is developed to predict the compressive strength of normal concrete made with periwinkle shell as coarse aggregate using a quadratic polynomial function. The response function is expressed as a multivariable function of the proportions of the component materials (water, ordinary Portland cement, sand and periwinkle shell). A total of thirty experimental runs were used to demonstrate the applicability of the mathematical model developed. The …
