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.

In Electrochemical Mechanical Planarization process (ECMP), concentrated phosphoric acid is usually used as electrolyte. Role of sodium dodecyl sulfate (SDS) in anodic dissolution of Cu in concentrated phosphoric acid was studied by Cyclic Voltammetry (CV), inhibition efficiency (IE) calculation and in-situ observation of the Cu electrode surface at anodic overpotentials. It was found that pres...

Kahang Cu Porphyry deposit is situated in the central part of a major Iranian magmatic belt, Urumieh-Dokhtar, in central Iran.There are several sub-volcanic stocks (e.g., porphyric granitoids rocks, quartz monzonite, diorite and monzodiorite-monzogranite)within Eocene volcanic and pyroclastic rocks consisting of basaltic, trachy-andesite and dacitic rocks. Hydrothermal alterations at the Kahang...

BACKGROUND In a biological system, an engineered nanomaterial (ENM) surface is altered by adsorbed proteins that modify ENM fate and toxicity. Thus far, protein corona characterizations have focused on protein adsorption, interaction strength, and downstream impacts on cell interactions. Given previous reports of Ag ENM disruption of Cu trafficking, this study focuses on Ag ENM interactions wit...

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...

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...

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...

Maharlu Lake, located in the SW of Iran, has acted as a sink for various wastewater discharges in the last few decades. This study aimed at assessing potentially toxic elements (PTEs) distribution in sediment, surface and pore water samples of Maharlu Lake. To achieve that, the samples were collected from each compartment and the total concentration of PTEs (Al, Fe, Sc, Cr, Co, Ni, Zn, As, Sb, ...

in this study, water samples were collected from 10 thermal and non-thermal springs of mahalat setting during four periods in 2011. the discharge rates of these springs vary from 2 l/s to 45 l/s and their temperature range from an average minimum of 18oc to maximum 47oc. spring water is high in so4-cl and this is related to gypsum dissolution. correlation coefficient, principal component analys...
