Investigation of the thermal stability of epoxy and unsaturated polyester filled with some agricultural waste of Dates palm (Phoenix dactylifera) and African elemi (Canarium shweinfurthii) pits particulate composites has been conducted at a heating rate of 10°C/min using thermogr...
The engineering of bandgap in materials is desired to develop new optoelectronic and photonic devices. The structure, electronic and optical properties of MgO (an insulator) mixed with CdO (a semiconductor) in the stoichiometry (0) are calculated using the ab initio density func...
This study focused on the effects of materials management on the performance of SMEs in Kogi State. For this study, the method used was research survey design. The population of the study comprised of the SMEs in food processing and manufacturing industries in the Eastern Senator...
The chemical formulae Ni1-xZnxGa0.5Fe1.5O4 (x= 0, 0.5, and 1) with spinel structure was prepared by a solid-state reaction at 1200 oC. The effect of irradiation by thermal neutrons is discussed on the structure by X-ray diffraction and by the Fourier transforms infrared absorptio...
Treatments of lignocellulosics material have been found to be useful in preparation of polymer composites since such treatment help to improve their properties. Epoxy filled with untreated and 5% NaOH treated date particulates of particle size 150 µm composites were prepared with...
This work focuses on the optimization of the adsorption technique using fatty acid grafted ogbono shell for the removal oil from polluted water surface. The shell was carbonized at a temperature of 600oC for 4h and then further modified with stearic acid. The surface morphology o...
Perylene (C20H12) is an important member of the polycyclic aromatic hydrocarbons (PAHs) that has a wide applications such as organic photovoltaic cells, field effect transistors and biosensors. Optimized bond lengths and bond angles, HOMO-LUMO energy gap, global chemical indices,...
The research focused on statistical evaluation of the impact strength on mild steel cladding weld metal geometry. The weld specimen of length 60 mm by width 40 mm and thickness of 10 mm was used for the experiment. A butt joint method was prepared and tungsten inert gas welding p...
The rapid growth in industrialization and urbanization as much as contributing to India’s growth story is also causing enormous negative environmental externalities. The sustainability of the industrial economy can be ensured only if the issues of resource constraints, energy ine...
Carbon nanotubes have demonstrated their versatility in the manufacture of various devices such as molecular probes, pipes, cables, fibers and springs. Recently, they have been used in cement composites to improve their physical and mechanical properties, but there are still many...
