The Kalmakyr deposit in Uzbekistan is one of the world’s largest gold-rich porphyry Cu deposits, and mineralization was proposed to be closely associated with emplacement latest intrusive phases, that is, granodiorite porphyry. However, it still unclear which features these ore-bearing intrusions are crucial for enormous metal enrichment how they correlate magmatic fertility. In this study, we ...

Cu is an essential cofactor for at least twelve mammalian enzymes including dopamine beta-mono-oxygenase (DBM), which converts dopamine (DA) to noradrenaline (NA). Previous studies reported that certain Cu-deficient (Cu-) rat tissues have lower NA and higher DA than Cu-adequate (Cu+) tissues, suggesting that DBM function was impaired. However, in vitro studies suggested that DBM activity is hig...

Tetrathiomolybdate (TTM) is a powerful and selective copper (Cu) chelator that is used as a therapeutic agent for Wilson disease. TTM is the sole agent that can remove Cu bound to metallothionein (MT) in the livers of Long-Evans rats with a cinnamon-like coat color (LEC rats). However, the administration of excess TTM causes the deposition of Cu and molybdenum (Mo) in the liver. In the present ...

Particles of sub-micron size possess significant capacity to adsorb organic molecules from aqueous media. Semiconductor photocatalysts in particle form could potentially be utilized for dye removal through either physical adsorption or photo-induced chemical process. The photocatalytic and adsorption capabilities of Cu₂O particles with various exposed crystal facets have been studied through se...

Background: Aras River is the main source of drinking water supply in northwestern provinces of Iran. The present study aimed to determine the concentration of heavy metals in the river on the border between Iran and Armenia. Methods: Three samples were taken from the Aras river water, the river bottom sediments and the root of Phragmites australis. In water sampling, the concentration of Hg, ...

Metal crystals were encapsulated in graphitic shells by evaporation of metal and carbon in an electric arc discharge [1–4]. Holes were drilled into the graphite cathodes and filled with a powder consisting of a mixture of graphite and a metal. Gold, platinum, molybdenum, or tungsten powders were used, respectively. An arc (40 V, 55 A) was operated for 510 seconds in a helium atmosphere (330 mba...

The main goal of this research work was to detect the different Cu mineralized zones in the Sungun porphyry deposit in NW Iran using the Spectrum-Volume (S-V) fractal modeling based on the sub-surface data for this deposit. This operation was carried out on an estimated Cu block model based on a Fast Fourier Transformation (FFT) using the C++ and MATLAB programing. The S-V log-log plot was gene...

X-ray transmission (XRT) and computed tomography (CT) was used on five samples from the Niaz porphyry Cu–Mo deposit in Iran, representing different alteration zones. Analysis of three-dimensional CT data revealed structural information groups elements with low, medium high attenuation, which were assigned to minerals previously determined by scanning electron microscopy. Thus, mineralization ca...

The mol-ecule of the title compound, [Cu(2)Mo(2)Br(2)(C(7)H(14)NS(2))(2)S(4)]·2C(3)H(7)OH, comprises one [(i-C(3)H(7))(2)NCS(2)](2)Mo(2)S(4) unit and two CuBr units held together by six Cu-μ(3)-S bonds, thus forming a cubane-like Mo(2)S(4)Cu(2) core. Intramolecular O-H⋯S hydrogen bonds may stabilize the structure. Two methyl groups of the two independent solvent molecules are disordered over tw...
