Heavy Metal Concentration and Health Risk Assessment of Selected Fruits Sold in Jos MetropolisAbstract The present study investigated the level of heavy metals in selected fruits sold commonly in Jos, Nigeria. The fresh fruits (Avocado pear, Black currant, Egg Plant, Golden melon, and Soursop) were purchased from five major markets (Terminus, Farin Gada, Building [...] 1206 7222 |
Effect of Convective Mixing Process on Storage of CO2 in Saline Aquifers with Layered PermeabilityAbstract Convective mixing of free-phase CO2 and brine in saline aquifers is an established technique to accelerate the CO2 dissolution process. Correct estimation of the convection onset time and rate of CO2 dissolution into brine are two [...] 727 5754 |

We greatly appreciate the contribution of expert reviewers, which is crucial to the journal's editorial process. We aim to recognize reviewer contr [...] 519 4332 |
Theoretical investigation of the single and double ionization spectra of M(CO)6, M = W and CrAbstract In this work, we study the single and double ionization spectra of the , with complexes by applying the four-component algebraic diagrammatic construction and Fock-space coupled cluster methods to extend earlier studies based on less demanding approaches. The computed single and double ionization po [...] 1236 6176 |
Synthesis of Tris(arylphosphite)-ligated Cobalt(0) Complexes [Co2(CO)6{P(OAr)3}2], and their Reactivity towards Phenylacetylene and DiphenylacetyleneAbstract The dinuclear complexes [Co2(CO)6{P(OAr)3}2] (1a, Ar = Ph; 1b, Ar = o-Tol) were prepared and reacted with PhC≡CH and PhC≡CPh to y [...] 1365 7809 |

Abstract The compound, [cis-dichloro-(tris-2-amino(ethylamine))cobalt(III)]chloride hydrate, [cis-Cl2-(tren)Co(III)Cl]·H2O, a conglomerate crystallizing in P21 with Z = 4 (Z’ = 2), has been used as a precursor in the synthesis of a new dicobalt(III) peroxo complex: [(μ2-hydroxo)(μ2-peroxo)bis(tris-2-amino(et [...] 1313 6851 |
1-Decylbenzimidazole Copper(II) Complexes: Combined Experimental and DFT PCM and TD-DFT Computational StudiesAbstract 1-Decylbenzimidazole (dbim) copper(II) complexes formed during solvent extraction were thoroughly studied, and their structures were predicted. Density functional theory (DFT) calculations of their structures and Time-dependent DFT (TD-DFT) calculations of their spectra indicated that 1-decylbenzimi [...] 1269 7132 |
A Preparation and Structural Characterization of the Hydrated Trifluoride Salt of the [Co(NH3)6]3+ Cation: [Co(NH3)6]F3 · 2H2O. The Unexpected Preparation of [Co(NH3)6](BF4)(SiF6) from Pyrex Glass, and the Syntheses and Structures of (NH4)[Co(NH3)6](BF4)2(2Cl) and of (NH4)[Co(NH3)6]2(SiF6)3(Cl) · 3H2OAbstract It is historically interesting to note that, whereas the [Co(NH3)6]3+ cation was isolated by Tassaert in 1798 (which he described as the tri-chloride) and that, in the early days of Coordination Chemistry, Jørgensen and Werner isol [...] 1216 7555 |
A Methodology to Estimate Net Proton: Phosphorus Co-Adsorption Ratios for Acidic SoilsAbstract Despite extensive research, the behaviour of the key nutrient element, phosphorus (P), in soil is not yet fully understood. This study focussed on the outstanding issue of the co-adsorption of protons (H+) and P by soils. We developed a congruent set of measures to determine the net H+:P co-adsorpti [...] 1284 8143 |
An Estimate of Possible Impacts of Superoxide Chemistry on Seawater pH: A Mapping ExerciseAbstract Superoxide, produced photochemically as well as microbially, is an important reactant present in seawater and a major source of hydrogen peroxide. Superoxide decay may occur through catalyzed or uncatalyzed dismutation forming H2O2 and O2, through oxidation to O2, or through reduction into H2O2. Und [...] 1127 6892 |
