Aim: Fibre serves primarily as support to the plant and its characteristics are essential for growth, being also a considerable factor for pulp and paper production. Debarking of tree logs is one of the steps in converting wood into chips suitable for pulping. However, the bark o...
Graphite as a conventional anode material has been unsuccessful in satisfying the requirements of future high-performance lithium-ion batteries due to its low theoretical specific capacity (372 mAh g−1) and low operating potential (~0.1 V). This has resulted in strong demand for...
Light plays an important role in many functions of the human body. It improves visual acuity, contrast sensitivity and colour perception while improving mood, memory and maintaining hormonal balance through the regulation of the sleep-wake cycle. The low wavelength violet-blue li...
In this study, the jute polyethylene nanocomposites were developed using hot-press technique. In order to enhance the compatibility between fiber, polymer and nanofillers, chemically treated jute (with 3-isocyanatopropyltriethoxy silane) and organically modified nanoclay were use...
Major problems encountered in industries, science and engineering is corrosion failure. The gravimetric, the electrochemical impedance spectroscopy (EIS) technique and Vickers hardness test were employed in investigating the anti-corrosion process of Aluminum alloy in acidic envi...
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...
