Investigation into the Bating Potential of Musa Accuminata (Banana) Peel in the Production of Leather

Bulus Habila*, Tashi Umar Tijjani, Saidu Simon Moses, Uwanta Emaime Jimmy, Gaiya Jonathan Danladi, Shekarri Ninnas Tachye, Muazu Balarabe Babangida, Ahmed Salim, Igbehinadun Olajide J., Adamu Audu

Increasing environmental pressures are forcing tanneries to reduce the level of nitrogenous compounds in generated effluents, due to strict regulations on effluent quality from various unit processes which bating plays a vital role. Bating imparts smoothness and stretchy effect to the resultant leather with the addition of proteolytic enzymes which are expensive, hence the need for alter...

The Re-Imagination of Electrochemical Power: A Global Awakening and Thoughts from Obafemi Awolowo University, Ile-Ife.

Aremo Bolaji*, Adeoye M. O., Obioh Imoh B, Okuwa Charles T, Oyinseye Shola I, Isadare Dayo A, Ayodeji Sodrudeen A, Abiodun Bukunmi J, Adeboye Odun A

From its humble beginnings as Alessandro Volta’s “voltaic pile”, electrochemical power (EP) has been power ing paradigm shifts in technology for the past 150 years. From the life-support systems in manned space explo ration of the 1960s, to the electric vehicles of the last 20 years, EP has been the unsung hero. EP is enjoying  renewed focus and a flurry of R&D activities in today’s resource-const...

Effects of Ingate types on Some Mechanical Properties of Cast Aluminium 6063 Alloy

Shittu M. D.*, Owolabi B. M, Ibitoye S. A, Olawale J. O.

This study examined the effects of inner-gate (ingate) types on some mechanical properties of cast aluminium 6063  (Al-Mg-Si) alloy. In this work, rods of aluminium 6063 alloy were cast using top gating, bottom gating and parting  line gating designs. Ingot of 6063 aluminium alloy was melted using crucible furnace and poured into already pre pared sand moulds. The casting from each gating system d...

Mechanical And Microstructural Properties Of Al-Sic Auto Brake Disc Rotor Composite

S. I. Kuye*, Oladerin Kolawole O, O. R. Adetunji, Makinde Victor O

Aluminium Matrix Composites (AMC) are combinations of aluminium alloy and other components usually non metal and commonly ceramic such as silicon carbide (SiC) and aluminium oxides (Al2O3) in order to improve the  engineering properties of the aluminium alloy. This research work examined the mechanical and microstructural  properties of Al-SiC auto brake disc rotor composite. Aluminium ingots were...

Study on the Thermal Properties of Epoxy Resin Reinforced with Arylidene-based Polybenzoxazine

Abdulrahman Musa*, Hamza A., Muhammad Abubakar Lawal

In this study, a new bis-arylidene derived benzoxazine: 2,6-bis((3-(2-hydroxyethyl)-3,4-dihydro-2H-benzo[e]  [1,3]oxazin-6-yl)methylene)cyclohexanone (HEB) was synthesized from its precursor: 2,6-bis(4 hydroxybenzylidene)cyclohexanone (BCH). The BCH was obtained as an aldocondensation product of cyclo hexanone and 4-hydroxybenzaldehyde, in an acid catalysed organic medium. Both HEB and BCH were ch...

Determination of the Suitability of Locally Available Aluminum Scrap for Production of Motorcycle Brake Shoe

Adeyemi S. S.*, Sogbesan A. O., Adetunji A. R., Isadare D. A, Olawale J. O., Adekoya O., Adeyemo O.

High demand for motorcycle and its spare parts in the country necessitate production of some of its parts locally to  conserve foreign exchange and create jobs. Brake shoes are one of the frequently replaceable parts in the motorcycle,  and hence, need for domestication to reduce pressure on importation. In this paper, aluminum scraps were obtained  from two local aluminum companies and were chara...
