In situ recovery (ISR) is the predominant method of uranium extraction in the United States. During ISR, uranium is leached from an ore body and extracted through ion exchange. The resultant production bleed water (PBW) contains contaminants such as arsenic and other heavy metals. Samples of PBW from an active ISR uranium facility were treated with cupric oxide nanoparticles (CuO-NPs). CuO-NP t...

This manuscript reports the use of nanoparticle-modified voltammetric sensors for rapid and green determination chemical oxygen demand in river waters from agricultural waste. Four different variants modified electrodes have been prepared: CuO nanoparticles electrogenerated over Cu covered with Nafion film (CuO/Cu-Nf), graphite–epoxy composites Cu, CuO, Cu–Ni alloy nanoparticles. The response f...

CuO-nanoparticles were found to be an excellent heterogeneous catalyst for C-arylation of active methylene compounds using various aryl halides. The products were obtained in good to excellent yield. The catalyst can be recovered and reused for four cycles with almost no loss in activity.

In this paper, CuO nanoparticles are synthesized using Tilia platyphyllos extract as reducing and stabilizing agents and TiO2are prepared via facile sol-gel method as an ideal support. FT-IR spectroscopy, UV-Vis spectroscopy, X-ray Diffraction (XRD), Scanning Electron Microscopy (FESEM), Energy Dispersive X-ray Spectroscopy (EDS), and Transmission Electron Microscopy (TEM) were used to characte...

In this research we are synthesized CuO nanoparticles (NPs) using water extract of. Also the total phenolic content of Sambucusnigra L. leaves water extract was measured by the Folin-Ciocalteu method. For confirmation the structure of synthesized bio-CuO-NPs we are employed X-ray Diffraction (XRD), Ultraviolet-visible (UV–vis), Fourier Transform Infrared (FTIR) spectroscopies, Scanning...

In this work, copper oxide nanoparticles have been synthesized via extractive Rosmarinus Officinalis leaves by simple and economic co-precipitation method at ambient conditions which it has used (CH3COO)2Cu+H2O individually as Cu sources. It was found that uniform copper oxide nanoparticles have been successfully produced at various temperature, namely 400, 600, and 800 0C. Powder X-ray Diffrac...

Cupric oxide (CuO) nanoparticles were prepared by the chemical route by calcinations at a higher temperature from 300 o C to 400 o C. For the comparison transmission electron microscopy (TEM) and x-ray diffraction (XRD) measurements were made through JCPDS. There is good agreement between data produced by spectroscopy and the microscopic measurements.

we report on the synthesis, morphology, chemically and structurally of tio2-cuo-sio2 nanostructure with different precursors molar ratio and calcined temperatures. in the present work, ternary reactive powders in the tio2-cuo-sio2 systems have been obtained using the sol-gel method, by the simultaneous gelation of all cations. the compounds and other elements change in special chemical and phys...
