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...
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...
