Carbon coated copper nanostructures as a green and ligand free nanocatalyst for Suzuki cross-coupling reaction
In this work, carbon coated copper nanoparticles and nanowires were synthesized as a ligand free nanocatalyst that naturally contains ppm levels of Pd with no post-modification via a two-steps reduction-hydrothermal process. Transmittance electron...

The Tanurjeh area is located in the Khaf-Darouneh volcano-plutonic belt, North of Darouneh Great fault. Eocene \\\\\\\\\\\\\\"Volcanicrocks such as rhyolite, dacite, rhyodacite and minor andesite are present. They are found ...
A Potentiometric Copper Sensor Based on Polypyrrole doped with 8- hydroxyquinoline-5-sulfonic acid
cyclic voltammetry and also constant potential technique. 8-hydroxyquinoline-5-sulfonic acid
(HQS) was doped in the polymer during electropolymerization process which acts as active
chelating agent and ionophore for copper recognition. Several factors...
Effects of parenteral supply of iron and copper on hematology, weight gain, and health in neonatal dairy calves
The objective of the present study was to examine the effects of parenteral
administration of iron and copper on hematological parameters, weight gain, and health of
neonatal dairy calves in the period when iron and copper deficiency...
Effect of copper content on the microstructure and mechanical properties of multipass MMA, low alloy steel weld metal deposits
Effect of copper content in the range of 0.14–0.94 wt.% on the microstructure and mechanical properties
of Cr–Ni–Cu low alloy steel weld metal deposits was investigated. All welds were prepared by manual
metal arc welding technique...
Histopathological study of cerebral lesions associated with copper deficiency in ovine aborted fetuses and newborn lambs
In an 2-year period, 2007–2009, 280 cases of ovine aborted fetuses and neonatal mortality were submitted to the Veterinary Teaching Hospital, Ferdowsi University of Mashhad. These included a majority of aborted fetuses, ...
Effect of Copper and Organic Matter on Copper Distribution in Two Calcareous Soils
Copper is an essential microelement for plants. Soil organic matter content and copper (Cu) are low in most cultivated soils of Iran. Sequential extraction has been used as a suitable method for identification of chemical forms of heavy metals...
