The corrosion behaviors of SUS 310S in model seawater with different metal cations have been investigated by gravimetric tests and surface analysis. Different corrosion rates were observed in different solutions by the kinds of metal cations, and Zn2+ containing solution showed t...
The potential for indigenous plant fibers to be used as composites in prospective materials and energy applications is growing all the time. SEM, FTIR, XRD, and XRF were used to investigate the potential of new Schizachyrium exiles leaf (SEL) and Raffia Africana otendor (RAOL) sp...
The inhibitive effects of plant leaf, Carica papaya leaves extract (yellow), CPLE (yellow) was studied on mild steel in 1.0 M HCl solution at 30oC using the gravimetric, electrochemical methods and Fourier transform infrared spectroscopy, FT-IR technique. The analysis of spectra...
The effect of hydrochloric acid treatment on the chemical composition of kaolin clay from Awgu Town in Awgu Local Government Area of Enugu State was studied in this work. The raw clay was mined, soaked in water to remove dirt, and sun-dried, followed by grinding to a particle siz...
Aims: To fabricate BiNixFe1-xO3 (x=0-1) ferrite films on a Si substrate with a thin Pt buffer using the spin coating method. Study Design: The focus of the study was two-fold: to examine the properties of the BiNixFe1-xO3 (x=0-1) family of materials and to determine whether Pt is...
The future value of graphite due to its use in lithium-ion batteries, and the scientific possibilities of graphene has markedly increased both the demand and consequently the price of natural flake graphite amidst flat global supply in the last decade. Despite the boom, most grap...
The photodegradation of two Azo reactive dyes (color index Yellow 145 and Blue 194) under sunlight using metal-organic framework MIL-53(Al) were evaluated in this research work. The synthesized material was characterized using FTIR and XRD techniques. The degradation process was...
This article is a review of the state of the art of the last decade on new materials based on cotton stem fibers (CTF) and natural binders such as Grewia Venusta Fresen bark, hulls fruits of Parkia Biglobosa, calyces of Bombax Costatum, etc. The results reported in the literature...
Aim: The structural, morphological and opto-electrical characteristics of cuprous oxide produced by thermal oxidation are investigated in this study. Methodology: Thermal oxidation of copper foils was used to develop high-quality cuprous oxide crystals, and the process proved to...
Currently, about 75% of the energy consumed in the world comes from fossils fuels and Kenya is no exception. Fossils fuels are delectable besides creating other environmental issues like global warming through the emission of green gases. Wood as a source of thermal heat energy i...
Direct conversion of sun energy to electrical energy using nanostructured organic/inorganic hybrid semiconductors is one of the best solutions for today’s energy crisis. In particular, researchers are turning their attention to incorporation of metal or transition metal oxide nan...
In this study, the influence of three submerged arc welding process parameters, namely welding current, welding voltage and travel speed on weld hardness of AISI 1020 mild steel plates has been studied by the application of Taguchi method and analysis of variance (ANOVA). The exp...
The study characterized bacteria isolates on the surface of corroded aluminium coupon. The biofilms on the surface of corroded aluminium material was tested by colony, biochemical test and gram staining reaction to know the microorganism(s) responsible for corroding aluminium cou...
The chemical composition of raw clay deposit in Awgu Town in Awgu Local Government Area of Enugu State, Nigeria was evaluated. The chemical property evaluation was done using x-ray fluorescence spectrometry, in addition to the determination of the loss on ignition test (L.O.I.) u...
Ca2MgSi2O7:Dy3+ (CMSD) white light emitting phosphor was synthesized by combustion route process. In order to find out the phase purity and crystal structure, characterization of the prepared powder samples was done by X-ray diffraction (XRD) technique. The results of the XRD stu...
