cupric oxide nanostructures were synthesized via a simple reaction between copper nitrate and sodium hydroxide using a sonochemical-assisted method. the synthesized cuo was then characterized using x-ray diffraction, scanning electron microscopy, transmission electron microscopy, fourier transform infrared, ultraviolet-visible and photoluminescence spectroscopy. our studies show that the cuo na...

New metal ion complexes of ampicillin were synthesis by two steps, first N-acylation with benzoyl chloride and sebacoyl chloride, In the second step, prepared compounds reacted cupric to form Cu- complexes. FT-IR, 1H NMR, 13C UV- visible, Elemental analysis, and, a theoretical study was used distinguish The biological efficacy compound found more active against bacteria.

(1) Calcium greatly increased crystallization of monosodium urate in otherwise pure water, by enhancing both nucleation and growth. (2) Acid accelerated urate nucleation, both by its direct action and indirectly by increasing the free calcium in physiological fluids. (3) Synovial fluid from one gouty patient accelerated urate nucleation, while that from one rheumatoid patient inhibited nucleati...

Quantum yields of hydrogen peroxide photolysis increase with the square root of concentration of added Cu(II). The cupric ions are photocatalytically active already at trace concentrations (10~7 M), i.e., at the concentrations present in any real reaction system. Hydrogen peroxide photolysis is completely suppressed on addition of complexing agents such as EDTA. It is believed that no hydrogen ...

Pig plasma benzylamine oxidase is a protein containing cupric copper and pyridoxal phosphate. The pyridoxal phosphate is stably linked to the enzyme. Discrepancies in the numbers of active sites per molecule of enzyme are reported in the literature. This paper shows that the fully active pure enzyme contains 3 mol of pyridoxal phosphate per mol, whereas enzymes with a lower specific activity ar...

Previous papers in this series have described the crystallization and preliminary characterization of beef plasma monoamine oxidase (1) as well as the fact that cupric copper is one of the prosthetic groups of this enzyme (2). In the present paper, studies related to the second prosthetic groups of this enzyme are presented and the results discussed. A preliminary report has already been publis...
