In this research, the uptake of Cu, Mo, Zn, As(III) and Cr(VI) by mesquite (Prosopis spp.) roots and shoots from two different sources was studied. The first source was seeds collected from plants grown in mine tailings in Arizona, USA (Seeds A) and the other source was seeds from a commercial vendor (Seeds B). In addition, the effects of above mentioned elements on plant growth and nutrient up...

A new coordination polymer of polyoxomolybdate, {[Cu(4)(bbp)(5)Mo(6)O(22)]·(H(2)O)(4)}(∞) (bbp = 1,4-bis(benzoimidazol-1-yl)phenyl), has been synthesized under solvothermal reaction, which represents a double-bridging interpenetrating α-Po network based on the bimetallic cluster {Cu(4)Mo(6)}. The thermogravimetric and electrochemical behaviors have also been studied.

Ab initio calculations show that a possible mechanism for the photomagnetism in copper octacyanomolybdate compounds consists of the initial excitation of the diamagnetic Cu(II)-Mo(IV-CS) pair to a Cu(II)-Mo(IV-T) state, whose geometry relaxation stabilizes the magnetic doublet and quartet states.

Molybdenum supported thin films of ScN, MgO and NaF with a Cu adatom have been studied in the framework of density functional theory. We have observed a charge transfer from the metal/film interface to the Cu atom and investigated its relation to surface and interface deformations. We find that a weak interaction between the metal and the film is a promising prerequisite for adatom charging. Th...

To investigate the correlations among seminal plasma Magnesium (Mg), Phosphorus (P), Potassium (K), Calcium (Ca), Chromium (Cr), Manganese (Mn), Iron (Fe), Copper (Cu), Zinc (Zn), Selenium (Se), Molybdenum (Mo) and Iodine (I) concentrations and semen parameters [1– 15]. 500 fertile and 1000 infertile males provided a standardized semen specimen. Total Magnesium (Mg), Phosphorus (P), Potassium (...

The title compound, (C(4)H(12)N)(3)[CuMo(2)S(8)]·C(3)H(7)NO, was obtained from the self-assembly of tetra-thio-molybdate, tetra-methyl-ammonium nitrate and cuprous sulfide in dimethyl-formamide (DMF). The asymmetric unit contains three (NMe(4))(+) cations, one [Mo(2)S(8)Cu](3-) anion and one DMF solvent mol-ecule, and no obvious inter-actions are observed between these species. The trinuclear a...

It is shown that the M2(DPhIP)4 molecules (M = Cr, Mo; HDPhIP = 2,6-di(phenylimino)piperidine) can each capture two CuI atoms to form molecules with linear Cu...M[symbol: see text] M...Cu chains. In these chains the CuI atoms have only weak interactions with the M atoms (Cr...Cu = 2.628 A; Mo...Cu = 2.615 A) even though their introduction causes marked decreases in the M[symbol: see text]M dist...

The Paraíba is an Au-Cu-Mo deposit located in the southern part of Amazon Craton, Alta Floresta Mineral Province, Mato Grosso State, Brazil. It composed Au-Cu-bearing quartz veins and Cu-Mo-rich hydrothermal breccias stockworks, both associated with several alteration zones. integration spectral (reflectance imaging spectroscopy) conventional techniques (core logging, petrography, mineral chemi...

1. Merino sheep fed on a diet of chopped wheaten hay, chopped lucerne (Medicago sativa) hay and oat grain were the source of rumen contents for the study. The diet contained (mg/kg dry weight) 3.3 copper, 0.24 molybdenum and 2.8 sulphur. The effects of adding between 5 and 25 mg Mo/kg as ammonium molybdate (AM) or tetrathiomolybdate (TTM) on the distribution and forms of Cu and Mo in rumen cont...

The Wunugetushan large porphyry Cu–Mo deposit in NE China is hosted by Mesozoic quartz monzonite and has a Mo-rich core Cu-rich rim space. In this paper, melt inclusions intrusions fluid different-stage veins were studied to explore potential parameters leading decoupling. Melt have rhyolitic compositions of 71.7–85.3 wt.% SiO 2 , 1.9–31.3 ppm Cu 1.7–2.6 Mo. Hydrothermal activity occurred over ...
