High‐Pressure Synthesis of a Novel Body‐Centered Tetragonal Vanadium Carbide

Elizabeth E. Cote, Tracey L. Nelson, Scott D. Ambos, John Arigbede et autres

ABSTRACT High‐pressure synthesis is a powerful tool for the discovery of new phases, and can be used to uncover new metastable phases even within well‐explored systems. The vanadium–carbon system is one of the most well‐studied binary systems due to its importance in …

A remediation approach for the petroleum industry using optimized biodegradable single-use SDS-surfactant in the treatment of soil contaminated with domestic-purpose-kerosene

Vincent Oshevwiyo Akpoveta, Ese Queen Umudi, Bright O. Ogbolu, Mabel Ajevwaye Afure et autres

Surfactants are known to aid in removing organic contaminants from soil. However, selecting a suitable surfactant for mitigating hydrocarbon pollution is an important environmental consideration during remediation. Previous studies report surfactant mixtures with a remediation focus on petroleum products, other than kerosene. …

High‐Pressure Synthesis and Recovery of Single Crystals of the Metastable Manganese Carbide, MnCx

Paul V. Marshall, Scott D. Thiel, Elizabeth E. Cote, John Arigbede et autres

Abstract Transition metal carbides find widespread use throughout industry due to their high strength and resilience under extreme conditions. However, they remain largely limited to compounds formed from the early d‐block elements, since the mid‐to‐late transition metals do not form thermodynamically stable …

Epoxidation of melon seed (Citrullus colocynthis L) oil: A kinetic and thermodynamic approach for industrial applications

V. O. Akpoveta, M. A. Fasasi, John Arigbede

Unsaturated melon seed oil had its epoxidation process studied at varied temperatures (30OC -70OC) within a three hours reaction time, for possible oxirane formation because of its industrial significance. Oil was extracted from melon seeds and characterized for its physicochemical properties using …
