Improper fibre volume analyses in most reinforced composites poses great challenges polymer industries which results to the production of with low mechanical strength. This study investigates fraction and impact strength analysis polyester composites. In this study, E-Glass fibres (hard soft mat) were mixed at different composition by volume. The E-glass serves as reinforcement polyester, fourt...

abstract sesbania grandiflora leaves are extensively used locally since ancient time as in traditional systems. base on mainly folkloric use, we investigated to know the potential of sesbania grandiflora leaves extracts through biological works in vivo and in vitro. the ethanolic extract of s. grandiflora leaves was partitioned into ethyl acetate soluble fraction (esf), petroleum ether soluble ...

In this article CuO/water nanofluid was synthesized by using polyvinylpyrolidone (PVP) as the dispersant.  Thenanofluid stability period and the heat transfer enhancement were determinedby measuring the thermal conductivities. To study the nano-fluid stability, zeta (ζ) potential, and absorbency were measured under different pH values and PVP surfactant concentrations; also thermal conductivity...
