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...
bioleaching processes for extraction of cu and mo from molybdenite cons. are more environmentally friendly and consume less energy than conventional technologies, yet less economically efficient. one necessary step towards arriving at a cost-effective bioleaching process is using appropriate methodology to optimize pertinent factors in such processes. to this end, the present study employed res...
Mineral resource classification is an important step in mineral exploration and mining engineering. In this study, copper molybdenum resources were classified using a combination of the Turning Bands Simulation (TBSIM) Concentration–Volume (C–V) fractal model based on Conditional Coefficient Variation (CCV) for Cu realizations Masjed Daghi porphyry deposit, NW Iran. research, 100 scenarios loca...
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...
A tubular array of TiO2 nanotubes on Ti matrix was used as a support for Ag or Cu sputter-deposited layers intended for surface-enhanced Raman scattering (SERS) investigations. Composite samples of Ag/TiO2-nanotube/Ti and Cu/TiO2nanotube/Ti were studied with the aid of scanning electron microscopy (SEM) and Auger electron spectroscopy (AES and SAM) to reveal their characteristic morphological a...
