Retraction of ‘Yttrium- and zirconium-decorated Mg12O12–X (X = Y, Zr) nanoclusters as sensors for diazomethane (CH2N2) gas’ by Terkumbur E. Gber et al., RSC Adv., 2023, 13, 25391–25407, https://doi.org/10.1039/D3RA02939E.
Cyanogen gas has been reported to be poisonous and poses a great threat to human life when been exposed to its high concentration. Hence, the need to develop sensor materials that have the potential of detecting cyanogen gas is aroused. In this work, using the density functional theory (DFT)-based HSE, M06-2X, PBE0, and ωB97X-D/6-311G + + (d, p) fu...
Diazomethane (CH2N2) presents a notable hazard as a respiratory irritant, resulting in various adverse effects upon exposure. Consequently, there has been increasing concern in the field of environmental research to develop a sensor material that exhibits heightened sensitivity and conductivity for the detection and adsorption of this gas. Therefor...
This study investigated the levels of pesticide residues in beans (Vigna unguiculata) in Wukari Local Government Area of Taraba State. Three samples of beans were randomly collected from Wukari township market (Yam, New and Old markets) and milled into powder form for pesticide residues concentrations analysis. The pesticide residue analysis was ca...
Human consumption of cyanide in cassava food products above the threshold has detrimental effect on the body system. This study investigated ten (10) different cassava products purchased to determine their levels of cyanide content. The residual cyanide in the cassava processed products were used as obtained without any pre-treatment, fermented for...
Consequent upon their widespread use as plasticizers and high volume of production, phthalates constantly diffuse and release into the various environmental components (air, water, soil) has become noticeable. In this study, levels and presence of phthalate esters were analyzed in newly purchased plastic toys and in polyethylene terphthalate (PET)...
This work evaluated the level of rancidity of edible oil in six (6) fried snacks food, namely, beans cake (Akara), groundnut cake (Kuli-kuli), bread buns, fried fish, fried yam chips and fried potatoes chips, purchased from hawkers in Wukari, Taraba State, Nigeria.. The rancidity indicators and their ranges in the samples obtained, include, Acid Va...
The isomers of C4H5N consisting of eleven members (2-vinyl-2H-azirene, Isocyanocyclopropane, Ally isocyanide, N-vinylethyleneimine, Cyanocyclopropane, 2H-pyrrole, 3H-pyrrole, Ally cyanide, 2-cyanopropene, 2-butenenitrile, Pyrrole) have been studied computationally using the Gaussian-4 (G4) compound model with the Gaussian 09 suite of programs. Quan...
Rapid industrialization has generated large quantities of liquid effluents from heavy metals such as cadmium, cobalt, lead, chromium, nickel, mercury, uranium, selenium, zinc, arsenic, gold, silver, copper and Manganese, etc. The presence of heavy metals such as chromium and cadmium with high level of toxicity detected in surface water has attracte...
