    Abstract: The structural properties and permeability of polycrystalline Ni0.6Mg0.4Fe2O4 ferrite are studied with the addition of Li2CO3 at 0%, 2%, 4%, and 6%. The samples were synthesized by the conventional ceramic method at 1300C sintering temperature for 6 hours. X-ray diffraction method is applied to understand the crystal structure of the following fer... Show More

    Abstract: The complex flow behaviour of partly crosslinked or highly filled polymer melts will be described with a new heuristic flow law, which takes into account the pseudoplastic flow behaviour in the regime of the viscosity curve for low and for high shear rates. The CARPOW law is a combination of the often used power and Carreau law. It describes the fl... Show More

    Abstract: The composites of biodegradable Polypropylene (PP) reinforced with short jute fiber were prepared by melt mixing followed by hot press molding. The composites were prepared with the aim to develop new biodegradable materials for different applications. Jute fiber is well known for its biodegradable properties but PP is not biodegradable material. T... Show More

    Abstract: The paper presents a green, simple and eco-friendly method to synthesize copper/copper oxide nanoparticles (Cu/CuO-NPs) from CuSO4 solution using aqueous extract of lemongrass leaf as the reducing and capping agent. The influence of some factors such as the volume ratio of lemongrass leaf extract and CuSO4 solution, pH and temperature to the synthe... Show More
