Duplex stainless steel are designed to provide better corrosion resistance, particularly chloride stress corrosion and chloride pitting corrosion, and higher strength than standard austenitic stainless steels. In Spray Forming processing, the gas atomizes a liquid metal stream an...
Sudden outbreak of the Coronavirus Disease (COVID-19) in December 2019 has brought global and domestic disturbances in the commodity market systems and processes. This has mostly affected the demand as well as the supply of the extractive sector commodities. The oil and gas marke...
The local availability of biowaste, which can be used as possible source of fibers, is an important trigger for research into new lignocellulosic materials for potential introduction into biocomposites: to evaluate this possibility, characterization is needed. In this work, soapb...
The corrosion of HVOF metallic coatings is a complex electrochemical process where numerous physical and electrochemical processes occurred at the surface. Researchers have adopted different approaches to study these processes. A significant cache of research material is availabl...
The present level of exploitation of Manganesemineral from its ore is very low due to depletion of its ore; therefore, there is need for appropriate processing technique that will help in providing solution to the exploitation problem encountered. Chemical, Petrological, Mineralo...
This article is aimed at carrying out comparative analysis of prepared erasable ink from locally sourced carboneous wastes (lampblack, tyre and coconut shell soot). Different formulation and modification were adapted in this research with effect to three different pigments for th...
Phytochemical analysis was carried out on the leaves and stem extracts of Commelinabenghalensis L and Acanthospermumhispidum DC plants to determine their corrosion inhibition potentials. The leaves and stem parts were processed by washing, air-drying under shade and then ground i...
Chlorella vulgaris was isolated from the African Regional Aquacultural Centre Aluu, Rivers State. The culture was grown and was analysed for oil contents using three different extraction methods and was also analysed for pigments and the algae oil was characterized. Pigment analy...
The performance of concrete samples mixed with different water sources, namely: tap water, river, borehole and hand-dug well from small scale mining catchment areas (known as “galamsey” in Ghana) was assessed. Concrete in the “galamsey” areas are being produced with these water s...
This research work reports the optimization and modeling of injection moulding parameters in the production of plantain fibre particles reinforced high density polyethylene (PFRHDPE) for impact responses evaluation. Composite materials have some limitations, and one of the most s...
The industry of plastics has grown rapidly since its inception in the 1940s, the use of plastics as an optical material only really started to pick up in the 1970s and has had a much slower underlying growth than for the commodity industry e.g. packaging, closures, etc. After tha...
Quantum dots (QDs) provide a powerful material to engineer various optoelectronics devices as well as it provides many opportunities in the biomedical field. QDs have received a great attention due to their significant properties. QDs are one of the foremost nanotechnologies to b...
This paper reports on the compressive strength and flexural tensile behavior of recycled polyethylene fibre reinforced concrete. Twelve concrete cubes of dimension 150 mm ×150 mm × 150 mm containing 0%, 0.25%, 0.50% and 1.0% of polyethylene fibres were cast and tested per BS 1881...
Aim: This study investigated the molecular characterization of hydrocarbon-utilizing rhizobacteria isolates from hydrocarbon-impacted mangrove soil from K-Dere Gokana and Gio Tai, Ogoni land, Nigeria. Study Design: Cross-sectional study. Place and Duration of Study: K-Dere Gokana...
This review surveys the research work published in the field of nanoclay (montmorillonite, MMT)-filled composites with particular reference to the effect of nanoclay (NC) introduction on the tensile, flexural, impact and compressive strength of nanocomposites. The matrix most fre...
