Feasibility of Synthesizing Potassium Carbonate Powder from Plantain Peels for Possibly Soap Making

Elelu Sheu Alimi*, Adio Oseni, Ayinla Baba Kuranga I, Alafara A. Baba, Tripathy Bankim Ch., Opadotun Dare, Musa Benjamen

The lack of chemical plants for the manufacture of simple chemicals such as NaOH, KOH and KCOin most part of 2 3  sub-Saharan African countries leads to high cost of importing these chemicals which make them less readily  available for many industrial purposes. An investigation was carried out using waste plantain peels to produce  potassium carbonate for industrial purposes such as paper making, ...

Physicochemical Parameters and Heavy Metals Characterization of Soil from Okpella Mining Area in Edo State, Nigeria

Edema O. G.*, Abel Inobeme, Olori E., Adekoya M. A., Obigwa P. A.

The present study examines the physicochemical parameters and heavy metal contents of soil from Okpella Mining  Area in Edo State. Top soil samples and   control  samples from about 200m from the mining area were analyzed for  their heavy metals content using Atomic Absorption Spectrometer (AAS) techniques. The pH, electrical  conductivity and organic matter were determined using standard procedur...

The Finite Element Modelling of Selective Laser Melting of Metals.

Oluwajobi A.O.*, Adebowale I.I.

The Selective Laser Melting (SLM) is one of the Additive Manufacturing (AM) processes and it is more favoured  over Selective Laser Sintering (SLS) because it can consolidate metal powders to a near full density (with relative  density of more than 99%) and it can achieve a surface roughness of less than 20µm. However, the SLM process  involves the use of high density energy laser to operate, by m...

Finite Element Modelling of the Effect of Cutting Speed on Machining NST 37-2 Steel.

Oluwajobi A.O.*, Egbebode O.E.

The Nigerian Steel (NST) 37-2 has vast applications as a substitute for foreign steels in Nigeria, but, its reliability,  the effects of induced residual stress in the material, optimum cutting parameters, efficient process planning, chip  formation process and surface roughness of the machined products are some of the challenges faced in the industry.  In this study, the finite element modelling ...

3-D Printing as a Veritable Tool for STEM and Non-Technical Education.

Oyelami A.T.*

Rapid Prototyping, which can also be referred to as Solid Freeform Fabrication, Additive Manufacturing, Layered  Manufacturing, or 3D Printing is a process of making a three-dimensional solid object of virtually any shape from a  digital computer model. This paper reviews the advances in this printing technology with a view to popularizing its  use for STEM and non-technical education among other ...
