Concentrations of heavy metals, pH, and particle size distribution parameters were measured in Dragica stream and Djetinja River water receiving wastewaters from copper rolling mill industry, Sevojno. The concentrations of copper, zinc, lead, and mercury were determined for water samples collected in summer 2009. It was found that Copper Rolling Mill Sevojno was the significant source of water ...

in this paper, synthesis of the flower-like zinc oxide was performed using microwave assisted dicationic ionic liquid [mmp(im)2 ]br2 . the polycrystalline flower-like zinc oxide nanostructure was obtained when a suitable mole ratio (ionic liquid /zinc acetate) and short duration microwave was used. x-ray diffraction (xrd), scanning electron microscopy (sem), and photoluminescence (pl) spectra w...

Quroum sensing system found in many species of bacteria, including Streptococcus agalactiae that use to regulate virulence and pathogenicity characteristics. So, this study achieved detect the inhibitory effect (CuO, ZnO, TiO2) nanoparticles on quorum agalactiae. The bacterial isolates were obtained from vaginal rectal swabs pregnant women who visited maternity children hospital Al-Diwaniyah ci...

A combined experimental and first principles study of Cu defects in bulk ZnO is presented. Cu particles are epitaxially deposited on the polar O-ZnO(0001) surface at room temperature. Upon heating, a broadening of the quasielastic peak in high resolution electron energy loss spectra is observed, corresponding to an electronic doping effect of Cu atoms in bulk ZnO with an ionization energy of 88...

High quality and purity single crystal ZnO samples doped with single isotopes of (63)Cu and (65)Cu, with equal concentrations of both these isotopes, and with natural Cu using a wet chemical atomic substitution reaction and anneal were studied using low temperature optical spectroscopy. Our data on the zero phonon line of the structured green band in ZnO confirm unambiguously the involvement of...

The aims of this study were to evaluate zinc, copper, and iron concentrations in the transitory milk of Korean lactating mothers and to investigate the relationship between these concentrations and maternal diet. Human milk samples were collected between 5 and 15 days postpartum from 96 healthy, lactating mothers in postpartum care centers in Seoul, Korea. Dietary intake during lactation was de...

introduction minerals and trace elements such as zinc and copper have significant influence on development and growth of the fetus and newborn. the purpose of this study was to determine the relationship between low birth weight and maternal and neonatal zinc, copper levels. materials and methods this case – control study   was done from september 2006 to sep 2007 consisted of 65 infants with b...

High-performance Cu/ZnO/(Al(2)O(3)) methanol synthesis catalysts are conventionally prepared by co-precipitation from nitrate solutions and subsequent thermal treatment. A new synthesis route is presented, which is based on similar preparation steps and leads to active catalysts, but avoids nitrate contaminated waste water.

This study investigated the association of copper and zinc levels in the serum or urine of patients living in northeast China, with either prediabetes or diabetes. From January 2010 to October 2011, patients with type 1 diabetes (T1D, n = 25), type 2 diabetes (T2D, n = 137), impaired fasting glucose (IFG, n = 12) or impaired glucose tolerance (IGT, n = 15), and age/gender matched controls (n = ...

To estimate the levels of serum zinc, copper and prostate specific antigen in patients with benign prostatic hyperplasia (BPH) and prostate carcinoma (PCa) and to correlate their levels as screening test in the diagnosis of prostate neoplasms. Serum zinc and copper were estimated in 25 patients of BPH and 18 patients with PCa over a period of one year. All patients were males and aged between 5...
