The Despite the array of old-grown date palm with reduced fruit yields in the northern part of Nigeria, the utilization of its biomass has not been fully explored by the wood-based industries in the country. This study was designed to assess the possibilities of using Date palm (...
Fly Ash, a solid waste (particulate matter) generated from a steel smelting plant was analyzed and characterized. Physical and chemical investigations of the fly ash from a steel manufacturing company was conducted using X-ray diffraction (XRD), Scanning electron microscopy (SEM)...
Acid hydrolysis of Cowpea seed husk was carried out using sulphuric acid with the concentrations of 0.1 M and 0.5 M at a reaction time of 10 to 90 minutes and temperatures of 130ºC to 170ºC. The substrates were characterised using proximate analysis. The effects of process parame...
The indiscriminate disposal of spent motor oil in the soil has led to the contamination of both land and water. The present study analyzes the compounds in spent motor oil from a car and the extraction from the soil of two mechanical workshops located in Gwagwalada area council o...
The current research work is to optimize the gas metal arc welding parameters on the impact strength, hardness and flexural strength of dissimilar weld joints of SS316L and AISI D2 steels by using Taguchi based grey relational method. The experiments were planned as per Taguchi L...
Objectives: This aim of this study was to synthesized CaO@SiO2 nanocomposite using solvent-free mechanochemical method and applied against gram-positive bacteria (Bacillus subtilis, Klebsiella pneunoniae) and gram-negative bacteria (Pseudomonas aeruginasa, Escherichia coli, and S...
This research deals with the study of the band structure, and density of state of silicon, using the first-principles pseudopotential method, based on the density functional theory (DFT) and the plane-wave method as implemented into Quantum Espresso (this is an open source softw...
Advances in engineering reliability and variability have allowed for a vast investigation into the dynamic failure of engineering materials in recent times than previously possible. This report aims to investigate and review the basic model in dynamic failure of High-Density Poly...
Water purification is slowly becoming a problem worldwide due to population growth. Lack of proper wastewater disposal from domestic and industrial sources has escalated water pollution in developing countries. Continuous pollution of water sources has made water purification for...
A refractory high entropy alloy based on MoNbTaW, with varying amounts of Ti and V, has been studied to elucidate the effect of the alloy composition on the electronic structure, phase stability, thermodynamic properties and the elastic properties. A synergistic approach has been...
This study evaluated the kinetics and thermodynamics of the extraction of beta-carotene from palm oil using acetone and ethanol. Six kinetics models which include; first order, second order, pseudo-first order, pseudo-second order, intra-particle diffusion model and power law mod...
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...
