Effect of Nanoclay Loading on the Hardness Property of Epoxy Composites

Egere B.C*, Yusuf L.O, Abdulkadir Suleiman Abdulrahman

This study examines the influence of nanoclay loading on the hardness properties of epoxy composites. Nanocomposites were fabricated using varying weight percentages of nanoclay and epoxy via the hand layup method with an open mould. Mechanical characterisation was carried out using a Rockwell hardness tester, while the dispersion and morphology of nanoclay particles within the epoxy matrix were a...

Structural and Optical Properties of Ag-Decorated ZnO Nanoparticles Synthesised via Hydrothermal Method for Optoelectronic Devices

Mohammed Isah Kimpa*, Muhammad Mustapha Kpanje, Haruna Isah, Fati Muhammad Abdullahi, Ahmad Alhaji Abubakar, Y. Titus, Isah Kasim Uthman

Zinc oxide (ZnO) nanoparticles have attracted considerable attention due to their wide bandgap and excellent physicochemical properties, making them promising materials for optoelectronic and photocatalytic applications. However, intrinsic defects such as zinc and oxygen vacancies introduce mid-gap trap states that promote charge carrier recombination, thereby limiting their performance. In this s...

Electrochemical Impact of Zinc-Magnesium Oxide-Cellulose Nano-particle Electrodeposited Composite Coatings on Low Carbon Steel in Sodium Chloride Media

Benedict Uche Anyanwu*, Owoeye S.O., Olamide O.O, Olaitan K.L, Anibaba A.D, Yussouff A.A, Okpako O

Low-carbon steel (LCS) is applied in numerous engineering applications, such as construction, automobile  manufacturing, and product and component manufacturing, due to its unique mechanical properties. They are readily  available, hence are very cost-effective when considered in any application. However, they are usually affected by  corrosion when exposed to chloride-induced media, due to the pe...

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

Abdulkadir Suleiman Abdulrahman*, Wakala B, Okpanachi Benjamin, 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 prepared sa...

Synergistic Enhancement of Mechanical and Thermal Properties of Hybrid Polyvinyl Chloride Composites Modified with Polyvinyl Acetate, Epoxidized Soybean Oil and Graphene Oxide

Ayanwale Olushola Johnmark*, Mamza Paul Andrew, Iyun Ogunkemi Risikat Agbeke

Polyvinyl chloride (PVC) composites modified with polyvinyl acetate (PVAc), epoxidized soybean oil (ESO), and graphene oxide (GO) were developed to investigate the synergistic effects of hybrid modification on mechanical and thermal properties. The composites were prepared using melt mixing followed by compression moulding. Tensile properties were evaluated in accordance with ASTM D638 standards, ...

Design and Performance Evaluation of a Battery-Assisted Fuel-Less Generator Using a Permanent Magnet Synchronous Generator with Automated Feedback Control

Ezekiel B Omoniyi*, Onyenefa Chukwuemeke O, John-Taiwo, Stella. O, Ajayi Sunday T

The energy insufficiency experienced in Nigeria is estimated to affect upwards of 85 million people, thus leading todependence on fuel-based generators. As such, environmental as well as socio-economic consequences are inevitable.This paper describes the process of designing, fabricating, and analyzing a closed-loop battery-assisted generator systemthat is fuel-free. The components used for the fa...
