The Jagpura Au-Cu deposit is situated within the Aravalli craton in northwestern part of India. In present work, petrography, mineral chemistry, fluid inclusion and sulfur isotopic compositions were used to study deposit. ore association arsenopyrite, loellingite, chalcopyrite, pyrrhotite pyrite, along with native gold, magnetite apatite. gold fineness ranges from 914–937‰ (avg. 927‰). presence...

The emergence of nematic electronic states accompanied by a structural phase transition is a recurring theme in many correlated electron materials, including the high-temperature copper oxide- and iron-based superconductors. We provide evidence for nematic electronic states in the iron-chalcogenide superconductor FeSe0.4Te0.6 from quasi-particle scattering detected in spectroscopic maps. The sy...

In order to maximize the utilization value of copper slag, a process smelting copper–iron alloy with slag is proposed here. The reduction kinetics by H2 are studied in this paper. main phases were Fe2SiO4 and Fe3O4. suitable conditions temperature 1373.15 K, partial pressure 40%, calcium oxide addition amount 30%. these conditions, metal ratio was 85.12%. after reduction, heated 1773.15 K for 4...

The way in which iron is handled by the duodenal mucosa, the reticuloendothelial system, the hepatic parenchymal cell, and the normoblast was investigated in copper-deficient swine.Copper-deficient swine failed to absorb dietary iron at the normal rate. Increased amounts of stainable iron were observed in fixed sections of duodenum from such animals. When (59)iron was administered orally, the m...

Nanoparticles have received much attention recently due to their use in cancer therapy. Studies have shown that different metal oxide nanoparticles induce cytotoxicity in cancer cells, but not in normal cells. In some cases, such anticancer activity has been demonstrated to hold for the nanoparticle alone or in combination with different therapies, such as photocatalytic therapy or some antican...

A simple flow injection analysis (FIA) method is described for the sequential determination of iron and copper. The detection method for iron and copper is based on their catalytic activities in the oxidation reaction of N,N-dimethyl-p-phenylenediamine (DPD) with hydrogen peroxide. The sequential determination of iron and copper can be carried out by injecting two sample plugs into the FIA syst...

In this work, we report synthesis of surface modified superparamagnetic iron oxide nanoparticles (SPION) by co-precipitation method using FeSO4.7H2O and Fe2(SO4)3.5H2O as precursors and trisodium citrate dihydrate as surfactant. Surface modification of the as prepared samples was performed in pot by sol-gel precipitation method u...
