About the Cover

Metal oxide nanoparticles have attracted tremendous interest as corrosion inhibitor due to their high surface area on metal surfaces. It is well known that zinc oxide nanoparticles (ZnONPs) have higher reactivity on basic and acidic solution. This article presents a method of synthesizing zinc oxide nanoparticles using Nypa fruticans (NIPA) starch and zinc oxide nanoparticles’ effect on corrosion inhibition in steel. Steel substrates were prepared and immersed in 0.5 M NaCl aqueous solution at 30 0C. The corrosion inhibition efficiency of 25% ZnONPs was determined by weight loss measurement, atomic force microscopy (AFM), scanning electron microscopy (SEM) and electron impedance spectroscopy (EIS) methods. Weight loss measurement was calculated and evaluated within 7 days and suggested that ZnONPs are effective as corrosion inhibitor. The surface morphology of the steel in the absence and presence of ZnONPs was investigated using Atomic Force Microscopy (AFM) and Scanning Electron Microscopy (SEM) techniques and the outcomes indicated a formation of a protective layer over the steel substrate with the ZnONPs. The Electron Impedance Spectroscopy (EIS) showed that charge transfer controls the corrosion process. The results and analyses of this work indicated that a zinc oxide nanoparticle is effective as corrosion inhibitor in steel. (Ref: Janet H Agresor, Karina Milagros R Cui-Lim.

The decline of Ekpe masquerade amongst the Efik speakers

Morenike Folabalogun

Masquerade traditions amongst the Efik speakers in Nigeria, is an interesting theme for discussion in art history. The scope of this paper is to direct attention to that aspect of Efik culture that is deeply rooted in the masquerade traditions and the importance of the masquerade’s cult.

Graphology: An Expressive Poetic Style of Deviation in Niyi Osundare’s Poetry

Tambari Ogbonanwii Dick

Graphological analysis of poetry has found its way into the poetic away from the tradition that governs the analysis of poetry. As a psychological representation of the writer’s state of being, it projects and illuminates the hidden meaning of an expression through the visual concept

Youth Participation in Electoral Processes

Chigozie Azunna, Sam Botchway

The study was carried out to provide an understanding of the participation of the Municipality’s youth in the local electoral processes. The objective of the study measured and examined the extent of youth participation in the local electoral processes of the Municipality, investigated and identified factors that prevents the youth from participating in electoral processes within the Municipality.
