Due to the high performance material requirement for automotive application and impact sensitivity of car bumper as one of the main car parts used as protection for passengers from collision and the safety requirement of the material to improve crashworthiness during low impact c...
More powerful of extraction natural dye from Neem leaves (Azadirachta indica) with respect to different dye bath concentrations in the range 20-80 g/L on wool fabrics was the aim of the present work. Also, the effect of artificial daylight up to 160 hours on the wool fabrics was...
Cement bonded boards 6 mm thick were produced using Thaumatococcus daniellii stalk. Thaumatococcus daniellii and cement were mixed together at two different mixing ratios and three board densities of 2.5:1 and 3:1 and 500, 600 and 700 g/cm3, respectively. After 24 h of cold-water...
G. arborea wood is a preferred choice for making musical instrument in Nigeria. However, its utilization is solely dependent on indigenous knowledge. Meanwhile, for optimum acoustic performance there is need to study acoustic properties of wood. Thus, this work aim to study the a...
In this paper, the potential capacitance of shea butter (SB) was studied using thermal influenced by varying the temperature between 30°C and 80°C, and distance between the plates from 1 cm to 3 cm. Though different samples were not used for this research, the qualities of variou...
Waste paper and sawdust poses huge problems as degrading urban environment, producing offensive odor during rain and pollute the air with smoke when burnt indiscriminately, thus contributing to environmental degradation and global warming. In addition, if not timely disposed, bec...
The objective of this study is to develop a process for producing alkali-resistant zirconium-containing glasses for use as a heavy metal retention matrix contained in fly ashes. For this, we have developed 5 glass compositions: Two alkali-resistant model glasses type CEMFIL, V1 (...
The main purpose of this study is to synthesize and investigate the optical and electrical properties of zinc sulphide (ZnS) thin film which has some interesting optoelectronic properties. The films were grown by chemical bath deposition (CBD) technique on clean soda-lime substra...
This work concerns the application of waste filler, consisting of scrap iron powder as received from machining in a small-scale workshop, in a self-produced thermoplastic starch (TPS) based on corn starch, acidified with acetic acid and plasticized with glycerol. The films obtain...
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...
