Cupric oxide should not be used as a copper supplement for either animals or humans.
Animal studies have shown conclusively that the copper (Cu) in analytical-grade cupric oxide (CuO) is unavailable for absorption from the gut (Aoyagi and Baker 1993, Baker et al. 1991, Cromwell et al. 1989, Ledoux et al. 1991). In fact, the bioavailability of Cu in CuO relative to that in CuSO4 z 5H2O is not significantly different from zero (Aoyagi and Baker 1993). This finding was important i...
متن کاملCupric oxide as an induced-multiferroic with high-TC.
Materials that combine coupled electric and magnetic dipole order are termed 'magnetoelectric multiferroics'. In the past few years, a new class of such materials, 'induced-multiferroics', has been discovered, wherein non-collinear spiral magnetic order breaks inversion symmetry, thus inducing ferroelectricity. Spiral magnetic order often arises from the existence of competing magnetic interact...
متن کاملFormation of Cupric Oxide Films on Quartz Substrates by Annealing the Copper Films
In the present work, cupric oxide (CuO) films were obtained through thermal annealing of the copper (Cu) films deposited on quartz substrates by DC magnetron sputtering method. The annealing was performed in air atmosphere for different times ranging from 60-240 min at temperature of 400 ºC. The influence of annealing times on structural and morphological properties of the films was investi...
متن کاملUtilization of copper in copper proteinate, copper lysine, and cupric sulfate using the rat as an experimental model.
One hundred twenty male Sprague-Dawley rats, averaging 108.6 g initial body weight, were used in two feeding experiments to evaluate the utilization of Cu in Cu proteinate, Cu lysine, and cupric sulfate. In Exp. 1, 60 rats were randomly assigned to 12 treatments in a 2 x 2 x 3 factorial arrangement of treatments, with Zn supplementation at 0 or 1000 mg/kg diet, Cu supplementation at 5 or 15 mg/...
متن کاملHybrid Nanocomposites of Montmorillonite/Copper Oxide, Synthesis and Evaluation as Effective Growth Inhibitors in Different Biological Systems
The external and interlamellar spaces of montmorilonite (MMT) were used as solid support for synthesis of CuO nanoparticles (NPs) at room temperature by the chemical reduction method. In this project, Copper Nitrate plus water (Cu(NO3)2. xH2O) and Sodium Hydroxide (NaOH) were used as Copper precursor and reducing agent respectively. Then, MMT/Cu2+ nanocomposites were stabilized with different r...
