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...

Dissolution Potential of a Nigerian Complex Covellite Ore by Ammonia-Ammonium Chloride Solution

Balogun Ayo F.*, Alafara A. Baba, Abdulkareem Aishat Y., Raji Mustapha A., Olasinde Fausat T., Muhammed Muhammed O., Folahan A. Adekola

With continuous industrial demands and as the market potential of purified copper in Nigeria and around the world  is on the increase, the development of  cheap and eco-friendly methods for the processing of mixed and lower  grade copper ores become paramount. Consequently, this study examines the effect of ammonia-ammonium  chloride concentration, temperature and particle size on the extent of co...

Experimental and Computational Studies of Terminalia Catappa Exudate and its Corrosion Inhibition Potential for Improvised Implant for Medical Application

Agbele I. E.*, Omoniyi K. I., Uba S., Nwokem N. E., Emmanuel E. G

Abstract  Conventional weight loss and thermometric have investigated the inhibitory efficiency of Terminalia catappa on the  corrosion of improvised metallic implants. The improvised metallic implant from the fan guard can be employed as a  short-time profile implant item for the purpose of implantation and fixation in animals after a comparative study with  the standard stainless steel. The GS-M...

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...

Evaluation of Bagasse Ash for Application in Glass Manufacture

Tagwoi J. T.*, Garkida A. D., Ali E. A., Asuke F., Yawas D. S.

Bagasse ash results from burning bagasse, a matted cellulose fiber residue from sugarcane that has been processed in sugar mills. In this paper, Bagasse ash has been chemically characterized in order to evaluate the possibility of its use in glass manufacture. The result of X-ray fluorescence (XRF) showed the ash to contain SiO2 - 31.67%, K2O - 31.41%, P2O5 - 8.14%, MgO - 4.89%, CaO - 3.92%, N...

Potential of Manihot Esculenta (Cassava) Peels for Electricity and Heat Co-Generation in Nigeria

S. I. Kuye*, Oyeniran Timothy O, Adekunle Nurudeen Olatunde, Benedict Uche Anyanwu, Olamide O.O

Nigeria is the largest producer of cassava in the world and the peel accounts for between 5 -15% of the tuber. Cassava peel  is often left unattended in the country, making it a source of methane gas which is one of the culprits of global warming.  Agricultural residues are good sources of renewable energy. This study investigated the potential of electricity and heat  generation from cassava peel...

A study on preferred footwear fastening mechanism for the prevention of diabetic foot complications

TAGANG J. I*, Chen R. C

Use of appropriate footwear among people suffering with diabetic foot complications has been well documented to play a vital role in the prevention and treatment of established foot diseases. The incidence and prevalence rates of diabetes in Africa are increasing and foot complications are rising parallel. However, there is a paucity of literature on the role of people suffering with diabetics ...

Synergistic Effect of Natural and Synthetic Polymers as Drag Reducing Agents in Single Phase Water Flow

Gimba Mohammad M.*, EDOMWONYI-OTU L C, Abubakar Abdulraheem, Nurudeen Yusuf.

One of the most power consuming applications in the process and petroleum industry is the turbulent means of  transporting fluid over long distances through pipelines. High pumping energy is required to overcome the  occurring frictional pressure drop. An economical approach has been reported where addition of small amount in  parts per million (ppm) of high molecular weight polymeric solution can...

The tanning potency of Landolphia owariensis on shoe upper leather

Bulus Habila*, Kogi Cecilia A, Dadah J.S, Igbehinadun Olajide J., Solomon Finfang, Sani M. Taofeeq

Landolphia owariensis belongs to the family Apocynaceae and its roots are commonly used as medicinal plant for the treatment of malaria and as purgative. The leaves extract is antimicrobial and the stem extract is used as a vermifuge. The phytochemical analysis of L. owariensis indicated secondary plant metabolites such as tannins, and flavonoids. The presence of tannins and flavonoids makes i...
