Effect of chemical modification on the flow and electrical properties of neem oil derivatives

ABDELMALIK A. A*, Umar S., Sadiq U.

Seed oil has been proposed as alternative base fluid for drilling mud but its stability to oxidation is still an issue to deal with. This paper reports the influence of stabilizing neem oil through chemical modification on its flow and electric conduction properties. Ester derivatives were produced from laboratory purified neem oil. The purified neem oil (PNO) was epoxidized to convert the doub...

Computational Study of CO Adsorption Potential of MgO, SiO2, Al2O3, and Y2O3 Using a Semiempirical Quantum Calculation Method

Oyegoke Ademola*, Oyegoke Toyese, Jacob John Olusanya

Air pollution has been a vital subject attracting experts' attention towards the search for ways in which the pollution can  better be controlled and minimized to avert the ongoing global warming and climatic changes experienced globally due to  the release of poisonous gas regularly release to our environment. The bulk of the discharged gases are traced to the use of  fossil fuel and the burning ...

Physico-Chemistry of Azara Barytes and its Suitability for Industrial Applications

Abdullahi, Y.*, Lawal, A. O

Azara baryte was subjected to analysis, revealing an average specific gravity of 4.3 g/cm³ and a loss on ignition of 1.71 wt%. The contents of Fe2O3, Al2O3, and BaO were determined using atomic absorption spectrometry. Gravimetric methods were employed to measure SiO2 and SO3, while flame photometry was utilized for the determination of CaO, MgO, Na2O, and K2O. The average percentage values for th...

Production of uniformly disperse carbon nanotube/high density polyethylene nanocomposite using novel nanofeeder injection moulding machine

GADIMOH S.*, IBRAHIM H. D, Kolawole E. G., NKEONYE P.O, MUSTAPHA A.

Uniformly disperse single-walled carbon nanotube (SWCNT)/High density polyethylene (HDPE) nanocomposite has been produced using the developed nanofeeder injection mould machine. The dispersion state of SWCNTs in the HDPE matrix was evaluated by transmission electron microscope and Atomic force microscope images and confirmed with conductivity test. It was found that the dispersion state of SWC...

Physical and Mechanical Properties of Filler Loading on Low- Density Polyethylene/Doum Fibre Composite

Abdulkadir S. A*, Wakala B, Okpanachi C B, Muktari S, Egere B.C, Yusuf L.O

This study investigates the physical and mechanical properties of low-density polyethylene (LDPE)/doum fibre composites with varying filler loadings. Six composite samples were fabricated using a metal mould of dimensions 120 × 120 × 3 mm, with LDPE and doum fibre mixed in ratios of 100:0, 90:10, 80:20, 70:30, 60:40, and 50:50. Processing was carried out at 120 °C for 5–10 minutes. The prepa...

Modelling reliability of distribution network fault diagnostic tools using petri-nets

OKORIE P U*, ALIYU U O, JIMOH B, SANI S. M

The aim of the work presented in this paper is to evaluate and develop a framework for reliability analysis of distribution system modeling and simulation using Petri-Nets. The problem of detecting, isolating and restoring fault events in dynamic systems modeled is considered. As the complexity of power system increases, fault diagnosis become very difficult task therefore necessitate the devel...

Gold Cyanidation and Characterization of Itagunmodi Gold Deposit using Cyanide from Cassava

Ogundare O. D.*, Adetunji A. R., Adeoye M. O.

This work has investigated gold cyanidation and characterization of Itagunmodi gold deposit using cyanide from cassava. The gold ore was subjected to selective removal of associated minerals, treated to varied concentrations of cyanide extracted from cassava and precipitation of the gold. The precipitated gold was characterized using optical microscope, SEM - EDX, EDXRF and XRFS. The result sh...

Physicochemical, Thermal and Cooling Curve Characterisation of Sulfate Salt–Modified Sesame Oil as a Potential Bio-Based Quenching Medium

Hafiz Bashir Aminu*, R. M. Dodo, Tever Ause, Ajah Ocholi

The development of environmentally safe quenching media is critical for sustainable heat treatment operations. Vegetable oils have emerged as promising bio-based alternatives to petroleum-derived quenchants due to their renewability, biodegradability and favourable thermal characteristics; however, their direct industrial application is often limited by inadequate thermal stability and sub-opti...

Influence of Fibre Properties on the Absorption Behavior of Aqueous Solutions in Web Structures

ILIYA E. B*, Abdulraheem Giwa, Sunmonu O K

Ten cotton varieties indigenous to the region were evaluated for their physical characteristics under standardized conditions using established protocols. Parallel-laid, cross-laid, and random-laid fibre webs with defined weight and dimensions (specific mass) were prepared from raw (unscoured), scoured, and scoured-mercerized samples of each variety. The vertical plane capillary rise of a dye solu...

Characterization of Some Selected Silica Sand Deposits in South West Nigeria for Sand Moulding in Foundry Industry

Omotajo Adewole Adeyemi*, Omotola Tobilola Emmanuel, Olawale J. Olawale, Isadare Dayo A, Adetunji A. R., Adekoya O., Adeyemo O.

This study determined the clay content, chemical composition, grain fineness number, distribution and shape of  some selected silica sand deposits in south west Nigeria. This is with a view to document the silica sand deposits in  Nigeria for sand moulding in the foundry industry. The silica sand deposits were collected from four river bed de posits in Igbokoda (Ondo State), Ote (Ogun State), Opa ...
