CuO, known to be multiferroic (MF) from ${T}_{L}\phantom{\rule{4pt}{0ex}}=\phantom{\rule{4pt}{0ex}}213\phantom{\rule{4pt}{0ex}}\mathrm{K}$ ${T}_{N}\phantom{\rule{4pt}{0ex}}=\phantom{\rule{4pt}{0ex}}230\phantom{\rule{4pt}{0ex}}\mathrm{K}$ at ambient pressure, has been the subject of debates about its ability exhibit multiferroicity room temperature (RT) under high hydrostatic pressure. Here we a...

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...

A total of 1110 broiler cockerels were used in three experiments to determine the availability of iron and copper from various sources. A skim milk basal diet was fed in each experiment using chicks maintained in battery brooders beginning at one day of age. Four organic iron compounds (sequestered iron A' and ferric choline chloride in Experiment 1 and sequestered iron B and C in Experiment 2)...

Abstract Cuprous oxide (Cu2O) nanoparticles were successfully synthesized using cupric hydroxide gel as a precursor and glucose reductant. A well-dispersed was prepared by treatment of aqueous cuprous chloride with anion exchange resin. The average diameter the Cu2O 780 nm. Attenuated total reflectance Fourier transform infrared spectroscopy showed that polyethylene from resin present in powder...

As a peroxidase mimic, cupric oxide nanoparticles were found to enhance the chemiluminescence (CL) of luminol-H(2)O(2) system up to 400 folds. The CL spectra and radical scavengers were conducted to investigate the possible CL enhancement mechanism. It was suggested that the enhanced CL could be attributed to the peroxidase-like activity of CuO nanoparticles, which effectively catalyzed the dec...
