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...

The Cu(In,Ga)(S,Se)(2)Mo interface in thin-film solar cells has been investigated by surface-sensitive photoelectron spectroscopy, bulk-sensitive x-ray emission spectroscopy, and atomic force microscopy. It is possible to access this deeply buried interface by using a suitable lift-off technique, which allows us to investigate the back side of the absorber layer as well as the front side of the...

Umbrella stoichiometries are relatively unstable compositions that can be leveraged to promote the formation of unconventional solid III II VI V V state structures. La and Cu in a one to one ratio is such a stoichiometry. The addition of a third metal such as Mo , V , or Ru generates a complex set of potential products. Nonetheless, La Cu MoO forms a single phase because no low energy multiphas...

The aim of this work was to investigate whether Cu, alone or in combination with Mo, reduces the Se status of sheep. Thirty-six Hampshire ewes were separated prior to mating into four treatment groups of nine sheep each. The four groups consisted of 1) basal (alfalfa hay or legume-grass low-moisture silage, corn, oats), 2) basal plus 10 mg Cu/kg diet, 3) basal plus 10 mg Mo/kg and 4) basal plus...

During the last 40 years, crop breeding has strongly increased yields but has had adverse effects on the content of micronutrients, such as Fe, Mg, Zn and Cu, in edible products despite their sufficient supply in most soils. This suggests that micronutrient remobilization to edible tissues has been negatively selected. As a consequence, the aim of this work was to quantify the remobilization of...

In this work, the concentration gradient (CG) analysis of local-scale exploration for Porphyry-Cu deposits is applied in two zones using the G(Vz) index (CG(Zn*Pb)/CG(Cu*Mo)). The first zone is covered by a 1:2000 map of the Sungun and Astamal areas in NW Iran and the second one in the Inza area in British Columbia, Canada. The rock samples are taken from Sungun and Astamal and the soil samples...

Ammonium tetrathiomolybdate (TTM) is the treatment of choice for chronic Cu poisoning in sheep and is recommended in Wilson's disease. However, the long-term effects have not been fully evaluated and some evidence questions the long-term safety of the drug. The aim of the present study was to investigate the systemic distribution and retention of Cu and Mo in TTM-treated sheep of different bree...

Under some conditions, the use of high-sulphur fertilisers has been thought to be associated with an increase in the incidence of copper deficiency among ruminants grazing the fertilised pastures or fed treated herbage. In this study 35 Romney lambs grazing ryegrass–white clover pasture of low molybdenum content (<0.5 mg Mo/kg DM) received dietary supplements of elemental S and Cu 3 times weekl...

The rumen is the site of significant interactions between Cu, S and Mo. It also shows reactions between Cu, S and Fe. The interaction between Mo and S results in the formation of thiomolybdates, which in the absence of adequate quantities of rumen Cu are absorbed into the animal and bind to Cu in biological compounds. This is the cause of thiomolybdate toxicity, often misleadingly called Cu def...

In this study, inductive coupled plasma-optical emission spectroscopy (ICP-OES) is employed for the evaluation of soil pollution for selected metals in the Vanderbijlpark area of South Africa. Soil samples investigated were collected from five different sites in the city based on their proximity to the industrial areas of Vanderbijlpark. Soil samples were collected from close to traffic robots,...
