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...
Ba2MgSi2O7:Dy3+ (BMSD) white light emitting phosphor was sintered by combustion synthesis route. The phase formation was confirmed with the help of XRD characterization. The results of the XRD study obtained for this phosphor revealed its monoclinic crystal symmetry with a space g...
Despite waste management within the industry contains a vital impact on each economic and environmental issues; the present level of construction waste management performance in Bangladesh is according as comparatively low. To improve any variety of management performance, it's n...
The stability of polymer-based organic solar cells is a crucial factor for the commercialization of solar cells. Testing of organic-inorganic nanostructures in polymer solar cells (PSCs) would be a better option to minimize the drawbacks due to the short lifetime. In this study,...
Introduction: Low cost refractory mixes of adequate resistance to molten glass attack is required for frit furnace lining, but when the corrosion behaviour of alumino-silicate type refractories are studied, kaolin is often neglected. Meanwhile clay is cheap in the study area and...
Abundantly available cassava peels waste was used to prepare porous activated carbon using a nontoxic activating agent, sodium thiosulphate (Na2S2O3). The activation was done under nitrogen flow at 8000C. The resulting porous carbon showed good surface area of 306 m2g-1. The supe...
