Influence of Weight Fraction on the Average Crystallite Size of Hybrid ZnO/Al2O3 Supported Bio-Waste Activated Carbon Composites

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

Due to the inherent high surface energy and the multifaceted interaction between them and the matrix interface, metal nanoparticles tend to coalesce in the absence of repulsive forces provided by a capping agent. It is therefore imperative to provide a support system that will moderate the spatial behaviour of the particles to prevent the formation of bulk particles a...

A Review of Some Welding Parameters and their Effects on the Heat-Affected Zone of Mild Steel Plate

S. E. Apeh^*, S. I. Kuye, O. R. Adetunji, Benedict Uche Anyanwu

Welding is one of the most important processes in manufacturing and construction industries. Various categories of welding exist and there are many welding processes available from which and industrial engineers can select for a particular application. The fusion category include the arc welding processes, resistance welding and gas welding methods; the non-fusion or solid state include cold w...

Treatment of Textile Liquid Effluents Using Activated Carbon from Palm Kernel Shells

ILIYA E. B^*

Effluents from the primary discharge points of two textile industries were subjected to analysis and subsequent purification utilizing particulate substrates derived from palm kernel shells. The shells underwent cleaning, milling, and sieving to produce four distinct particle size fractions. Five-gram aliquots of raw, carbonized, and chemically activated (using FeCl3, CaCl2, and a 2:1 ZnCl2:Fe...

Microstructure and Hardness Profiles of Hybrid Laser-Arc Welded Joint for UltrahighStrength Steel.

Olugbade Emmanuel^*, Zhou Bin, Ikeagwuonu Clement, Yang Li, Huang Gen-Zhe

In this investigation, hybrid laser-arc welding was performed on 6-mm thick ultrahigh-strength quenched and tempered steel plates. Laser-arc welds were characterized for hardness and metallurgical properties in three defined cooling cycles. Destructive tests of the joints revealed that the joints were characterized by tensile strength similar to that of the base material. Microstructural charac...

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, ...

Quantitative Evaluation of Carbon-Enriched Stabilised Austenite in Cast Austempered Ductile Iron of Varying Section Thickness

Olawale John Oluyemi^*, Ibitoye Simeon Ademola, Oluwasegun Kunle Michael.

The quantity of carbon-enriched stabilised austenite (γHC) in austempered ductile iron (ADI) with various casting thicknesses was evaluated in this study. Ductile iron grade that conforms to ASTM A536 65-45-12 was cast, specimens of section thickness in the range of 5 to 25 mm were machined, isothermally treated to 820°C austenitising temperature, and austempered at austempering temperature (T ...

Synthesis and Characterization of Zeolite-Goethite Nanocomposite

Adegoke H. I.^*, Bello M. O., Dolapo A. F.

In recent years, nanocomposite materials have received much interest in nanotechnology. This new trend in nanotechnology is aimed at producing materials of unique properties. In view of this, zeolite goethite nanocomposite was synthesized to reinforce zeolite properties. Zeolite was synthesized hydrothermally from sodium aluminate, sodium silicate and sodium hydroxide at 100 oC for 24 h. The compo...

Production of citric acid from lemon and cassava waste peels

NWOSU F O^*, KAREE A O

The high demand for citric acid by many industries cannot be over emphasized. Presently, 70 % of the total citric acid produced globally is consumed by food industries, 12 % by pharmaceutical industries and the remaining 18 % by other industries. Moreover, rapid increase in food/beverage industries in Nigeria with no known company producing citric acid in Nigeria makes its scarcity severe. Cass...
