The published crystal structure in the paper by Zibaseresht & Hartshorn (2006) is almost certainly that of the nickel complex and not the copper complex as originally identified. Refinement of the copper occupancy was consistent with the presence of a lighter transition metal ion in the structure, and residuals improved significantly when the complex was refined as the nickel or cobalt salts. U...

The polycrystalline aluminium substituted nanoparticle size copper cobalt ferrite samples CuxCo1-xFe2-2yAl2yO4 (where x= 0.0, 0.2, 0.4, 0.6, 0.8, 1.0; y = 0.05, 0.15 and 0.25) have been prepared by standard ceramic technique. The lattice constants of the phases are evaluated from x-ray diffraction data. The effects of Al on both AC and DC Electrical properties are studied. DC Electrical resisti...

The active centers of carbon catalysts doped with cobalt, nickel, copper, manganese, zinc, and chromium were modeled by density functional theory methods. Likewise, the thermodynamics oxygen reduction reaction (ORR) on model determined. features chemical properties chromium-containing material, namely its spontaneous oxidation into hydroxo form, revealed. In addition, it was established that am...

Copper hexacyanoferrate (CuHCF) is a promising Zn2+ insertion material as positive electrode in mild aqueous Zn-ion batteries for power grid applications, due to its excellent capability, non-toxicity, low cost and easy synthesis route. Here, the effect of reactants’ concentration ratio during CuHCF on performance resulting has been investigated through morphological, crystallographic compositi...

Within the last 18 months there have developed two theories concerning the inorganic factors which influence hematopoietic processes. (I) In rats on a basal diet of milk and iron, supplementary copper alone will stimulate a maximum hemoglobin production. (2) On such a diet a group of elements including copper produces a maximum hemoglobin response while copper alone is slightly less effective. ...

The transaldolase-dihydroxyacetone carbanion intermediate formed in the reaction of transaldolase with its donor substrates fructose-6-P or sedoheptulose-7-P is susceptible to oxidation by hexacyanoferrate(III). The dihydroxyacetone moiety is oxidized to the corresponding 2-ketoaldehyde, i.e. hydroxy-pyruvaldehyde (CH2OH-CO-CHO). This oxidation product is, in contrast to dihydroxyacetone, readi...

A synthetic growth medium was purified with the chelator 1,5-diphenylthiocarbazone to study the effects of copper on partial reactions and product formation of nitrite respiration in Pseudomonas perfectomarinus. This organism grew anaerobically in a copper-deficient medium with nitrate or nitrite as the terminal electron acceptor. Copper-deficient cells had high activity for reduction of nitrat...
