This work focused on the removal of methylene blue dye from aqueous solution using modified clay from Ngbo clay deposit in Ebonyi State, Nigeria. The clay was modified to zeolite by alkaline activation at a high temperature. Characterization of the clay was used to determine the...
New Schiff base ligand was synthesis via a condensation of the ligands in methanol. The Schiff base were synthesized in 1:2 molar ratio reactions. The complexes [Mn(HL1)2Cl, Cu(HL1)2 and Ni(HL1)2Cl] have been characterized on the basis of FTIR, electronic spectra, melting points/...
Metal complexes have been synthesized by the reaction of thiophene-2- aldehyde thiosemicarbazone with Cu(OAc)2 and Ni(OAc)2. The thiosemicarbazone coordinates to metal ions through the thionic sulfur and the azomethine nitrogen. The thiosemicarbazone is obtained by the reaction o...
Photodegradation of methyl orange spectrum in aqueous ZnO suspension by UV irradiation has shown time-dependent UV photodegradation. Methyl orange shows absorption peaks at 463 nm in the visible region. The rate of decolourization was recorded with respect to the change in the in...
In this initial investigation, oil palm empty fruit bunch (OPEFB) biocomposites incorporated with nickel zinc ferrite (NZFO) were prepared via heat blending technique followed by a compression molding technique, the percentages of NZFO were varied from 2.5 to 12.5%. All microwave...
The study was carried out to identify the types of non-farm activities engaged in by rural women in Kajuru LGA of Kaduna State and the type of activity that substantially improves their income as an indicator of empowerment. Data obtained through questionnaire were analysed using...
This study investigates the synthesis and characterization of organophilic bentonite, from natural organophobic bentonite from Ebenebe Anambra State, Nigeria. The clay was used after milling and drying at 110°C overnight. The natural bentonite was then converted to sodium bentoni...
An empirical model is developed and tested on cubic solids for the calculation of bandgaps. The dataset for the model is derived from a semi-local approximation in which the local density approximation (LDA) treats the exchange-correlation energy and potential. The agreement betw...
The inhibitive performance of aqueous Vigna unguiculata coat extract on the corrosion of pipeline steel in 0.5 M HCl solution was studied by electrochemical, Gravimetric and UV-Visible spectroscopy techniques at varying temperatures. The extract was characterized using Gas Chroma...
Cassava peels have been recognized as an ecological burden for the society. Their main advantageous application is animal feeding. However, cassava peels, as many lignocellulosic biomass-rich materials, have stimulated new gateways for the production of renewable, low cost and su...
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...
