Calculation and optimization of the copper (II) sulphate monohydrate from copper (II) sulphate pentahydrate production process in a fluidized bed dryer [PDF]

open access: yesHemijska Industrija, 2015
In this paper the process of the copper (II) sulphate monohydrate from copper (II) sulphate pentahydrate (also known as a Blue vitriol or Bluestone) production was analyzed.

The Oxidative Coupling of 2,6-Xylenol Catalyzed by Polymeric Complexes of Copper, 2. Physicochemical Study on Copper(II) Complexes of Partially Dimethylaminomethylated Polystyrene [PDF]

open access: yes, 1977
The polymeric catalyst formed by complexation of copper(II) chloride and partially dimethylaminomethylated polystyrene was investigated to explain its behaviour in the oxidative coupling of 2,6-xylenol.

Inhibition of phosphofructokinases by copper(II) [PDF]

open access: yesFEMS Microbiology Letters, 2001
The biochemical inhibition by Cu2+ on eight phylogenetically and biochemically different phosphofructokinases (PFKs) was investigated. The enzymes screened included representatives from thermophilic and mesophilic bacteria, a hyperthermophilic archaeon and a eukaryote, covering all three phosphoryl donor subtypes (ATP, ADP and pyrophosphate).

A minimalist chemical model of matrix metalloproteinases- Can small peptides mimic the more rigid metal binding sites of proteins? [PDF]

open access: yes, 2013
In order to develop a minimalist chemical model of matrix metalloproteinases (MMPs), we synthesized a pentadecapeptide (Ac-KAHEFGHSLGLDHSK-NH2) corresponding to the catalytic zinc(II) binding site of human MMP-13.

Q-band electron nuclear double resonance (ENDOR) and X-band EPR of the sulfobetaine 12 heat-treated cytochrome c oxidase complex [PDF]

open access: yes, 1997
Heat treatment of the bovine cytochrome c oxidase complex in the zwitterionic detergent sulfobetaine 12 (SB-12) results in loss of subunit III and the appearance of a type II copper center as characterized by electron paramagnetic resonance (EPR ...

Structurally Distinct Active Sites in the Copper(II)-Substituted Aminopeptidases from \u3cem\u3eAeromonas proteolytica\u3c/em\u3e and \u3cem\u3eEscherichia coli\u3c/em\u3e [PDF]

open access: yes, 2002
The aminopeptidase from Aeromonas proteolytica (AAP) was titrated with copper, which bound sequentially at two distinct sites. Both the mono- and disubstituted forms of AAP exhibited catalytic hyperactivity relative to the native dizinc enzyme ...

A copper(II)-copper(II) bond in a dimeric molecule of a mineral [PDF]

open access: yesActa Crystallographica Section A Foundations of Crystallography, 2009
Copper(II) acetate monohydrated, mineral hoganite, shows a dimeric structure with four acetate residuals bridging a metal-metal moiety. The ferromagnetism of the compound has been attributed to spin pairing obtained either through a direct Cu(II)-Cu(II) bond or through the carboxylate ligands.

Absorption spectra of gelatin copper complexes and copper (II) sulfate and their impact on cotton peroxide bleaching

open access: yesJournal of Natural Fibers, 2019
A gelatin copper complex was synthesized with gelatin and copper (II) sulphate. The previous study had indicated that the gelatin copper complex could improve peroxide bleaching effectiveness of cotton in low-temperature.
