Evaluation of the Effects of Weight Fraction on the Average Crystallite Size of ZnO Supported Bio-Waste Activated Carbon Composites

Onuoha David Chikaorama^*, Egbe Evudiovo Apha Peter, Abdulrahman Asipita Salawu, Abdulkareem Ambali Saka

Metal nanoparticles are known to possess outstanding mechanical properties, relative to their bulk materials. However, due to large surface energy, nanoparticles tend to coalesce to each other, forming bulk particles and eventually deteriorate in quality. It is therefore, essential to immobilize nanoparticles on a support to help particles stay away from each other. This paper reports the effec...

Agronomic Usefulness of Anaerobic Slurry on Tomato (Lycopersicum Esculentum) Seedlings

Maliki Muniratu^*, Esther Uwidia Ikhuoria

Current anaerobic digestion technologies are geared towards maximizing biogas yield and the subsequent use of the anaerobic slurries as soil amendments. However, only few studies have established the agronomic risk associated with the utilisation of anaerobic slurries. Therefore, this study evaluates the effect of agronomic use of anaerobic slurry on lycopersicum esculentum seedlings. L. escule...

Optimization of the Green Synthesis of Tin Oxide Nanoparticles by Response Surface Methodology (RSM) using Box-Behnken Design.

Kareem Aduagba Ganiyu^*, Abdulrahman Asipita Salawu, Abdulkareem Ambali Saka, Tijani Jimoh Oladejo

Tin oxide nanoparticles has been synthesized via green route using SnCl .2H O and Euphorbia trigona (African  2  2  cactus) plant extract as precursors. In this green route process parameters such as, solution pH, precursor concentration  and synthesis temperature were optimized to produce nanoparticles with smaller size. The degree of sensitivity of the  process parameters vis-a-viz towards optim...

Synthesis and Surface Characterisation of Cu-Doped Tin Oxide Thin Film for Optoelectronic Applications.

Adewumi Olusegun Emmanuel^*, Taleatu Bidini Alade, Adewinbi Saheed Adekunle, Busari Rafiu Adewale, Oyedotun Kabir Oyeniran, Omotoso Ezekiel

Copper doped tin oxide thin film was synthesised by electrodeposition technique. Film growth was maintained at  cathodic potential of 1.60 V at a varied deposition time. Surface morphological studies of the deposited films were  achieved by field emission scanning electron microscopy (FE-SEM). The scanning electron microscopy image revealed  evenly distributed films, across the substrate with rice...
