Ternary solubility phase diagrams of mandelic acid and N-methylephedrine species in chiral solvents, (S)-methyl lactate, (S)-propyl lactate, and (S)-butyl lactate, have been determined. Solubility measurements were performed ...

Advances in nanotechnology have led to the fabrication of nano-constructs of organic or inorganic origins with well-defined structures, surface properties, and can be made to respond to physical or chemical stimuli. These ...

Several novel thiocarbohydrate phosphinogold(I) complexes were prepared via the reaction of n-gluconamidoalkyl thiol (L1–L7) {where L1–L4 = n-gluconamidoalkyl thiol (n = 1–4),L5– L7 = acetylated n-gluconamidoalkyl thiol ...

Investigations were conducted over a twelve-month period in 3 years on the operational strategy of the larger of the only two sanitary landfills and leachate treatment ponds in Ghana and sub-Sahara Africa. The purpose was ...

The general performance of ten spectrophotometric reagents, namely salicylaldoxime, 22'-dipyridyl, dimedone, 8-hydroxyquinoline, dithiooxamide, cupferron, nioxime, 4-methylnioxime, 1,lO phenanthroline hydrate and a-benzoin ...

An environmental pollution investigation was carried out to determine the concentrations of aluminum (Al), arsenic (As), cadmium (Cd), and mercury (Hg) (heavy metals) in the surface water and river water bed sediments of ...

Mixed-ligand palladium(II) chloride complexes bearing the nucleobases, adenine (Ad), cytosine (Cyt), and guanine (Gua), have been synthesized and characterized by UV-vis spectrophotometric methods, magnetic susceptibility, ...

Polychlorinated biphenyls (PCBs) in tropical soil samples from the Central Region of Ghana, and their variation with the soil characteristics were assessed. The soil characteristics of seventy eight samples were first ...

This paper discusses the nutrients budget and transfers of mineral nutrients from land to the sea that influence significantly the biogeochemical process operating in the coastal ecosystem. Water samples were collected ...

A systematic study of the ternary solubility phase diagrams of chiral mandelic acid species in the chiral solvents (S)-methyl lactate, (S)-propyl lactate, and (S)-butyl lactate has been carried out. Solubility measurements ...
