Received: 27 February 2021;  Published: 12 May 2021;  doi: 10.21926/acr.2102013

Abstract

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 materials, Bukuru, and Fobur) in Jos. Each fruit sample was collected in triplicate and [...]

Effect of Convective Mixing Process on Storage of CO2 in Saline Aquifers with Layered Permeability

Received: 19 October 2020;  Published: 25 February 2021;  doi: 10.21926/acr.2101012

Abstract

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 crucial parameters regarding safety issues, as the timescale for dissolution corresponds to the same time over which the [...]

Theoretical investigation of the single and double ionization spectra of M(CO)6, M = W and Cr

Received: 26 April 2020;  Published: 14 December 2020;  doi: 10.21926/acr.2004010

Abstract

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 potentials are in good agreement comparing with the avail [...]

Received: 07 September 2020;  Published: 25 November 2020;  doi: 10.21926/acr.2004009

Abstract

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 yield dimetallatetrahedranes [{(ArO)3P}(OC)2Co-Co(μ-RC≡CPh)(CO)2{P(OAr)3}] (3a, Ar = Ph, R = H; 3b, Ar = o-Tol, R = H; 3c, Ar = Ph, R = Ph; 3d, Ar = o-Tol, R = Ph). The main reaction of diphenylacetylene was accompanied [...]

The Unexpected Synthesis of a New (μ2-hydroxo-μ2-peroxo) Dicobalt Complex

Received: 26 July 2020;  Published: 07 September 2020;  doi: 10.21926/acr.2003008

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(ethylamine))di-cobalt(III)] tris(triiodide) dih [...]

1-Decylbenzimidazole Copper(II) Complexes: Combined Experimental and DFT PCM and TD-DFT Computational Studies

Received: 29 June 2020;  Published: 27 August 2020;  doi: 10.21926/acr.2003007

Abstract

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-decylbenzimidazole forms both mono- and binuclear complexes with [...]

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) · 3H2O

Received: 28 June 2020;  Published: 23 July 2020;  doi: 10.21926/acr.2003006

Abstract

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 isolated many of its other salts, the fluoride was never reported. In fact, in relatively modern times, lack of success was [...]

A Methodology to Estimate Net Proton: Phosphorus Co-Adsorption Ratios for Acidic Soils

Received: 07 November 2019;  Published: 13 April 2020;  doi: 10.21926/acr.2002005

Abstract

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-adsorption ratio and tested it on goethite, for which a ratio [...]

An Estimate of Possible Impacts of Superoxide Chemistry on Seawater pH: A Mapping Exercise

Received: 05 September 2019;  Published: 21 January 2020;  doi: 10.21926/obm.acr.2001004

Abstract

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. Under definite circumstances, the redox processes that [...]

Vanadium is an element that is widely distributed in Earth’s crust as well as in sea-water and ground-water reservoirs. Therefore, it exerts a great influence on the issues related to life and environment. Vanadium is utilized by several marine organisms. For example, there are vanadate-dependent haloperoxidases in algae and several bacteria, e.g [...]
