copper sulfate was used as a precursor to prepare cuo nanoparticles in reverse micelles (o/w microemulsion).  this is a technique which allows the preparation of ultrafine metal oxide nanoparticles within the size ranging from 50 to 60 nm. the preparation of nano copper (ii) oxide studied was investigated in the inverse microemulsion system. therefore the nucleation of metal particles proceeds ...

The increasing use of manufactured nanoparticles (NP) in different applications has triggered the need to understand their putative ecotoxicological effects in the environment. Copper oxide nanoparticles (CuO NP) are toxic, and induce oxidative stress and other pathophysiological conditions. The unique properties of NP can change depending on the characteristics of the media they are suspended ...

Copper oxide nanoparticles within hollow mesoporous silica spheres were prepared by binding/adsorbing Cu2+ or [Cu(NH3)4(H2O)2]2+ ions on the surface of carbon spheres, followed by formation of a mesoporous silica shell by sol-gel processing and calcination in air. The CuO nanoparticles can subsequently be converted into Cu3N nanoparticles by nitridation with ammonia. The effect of the different...

Hierarchically mesoporous CuO/carbon nanofiber coaxial shell-core nanowires (CuO/CNF) as anodes for lithium ion batteries were prepared by coating the Cu2(NO3)(OH)3 on the surface of conductive and elastic CNF via electrophoretic deposition (EPD), followed by thermal treatment in air. The CuO shell stacked with nanoparticles grows radially toward the CNF core, which forms hierarchically mesopor...

CuO nanoparticles (CuO-NP) were synthesized in a hydrogen diffusion flame. Particle size and morphology were characterized using scanning mobility particle sizing, Brunauer-Emmett-Teller analysis, dynamic light scattering, and transmission electron microscopy. The solubility of CuO-NP varied with both pH and presence of other ions. CuO-NP and comparable doses of soluble Cu were applied to duckw...

nano structured materials have wide range of applications due to their interesting size-dependent chemical and physical properties compared to particles of size in the range of micrometer. copper oxide nano materials are of interest on account of their potential uses in many technological fields. in this study  cuo nanoparticles were synthesized via simple sol gel method using basic cuso4 as we...

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...

The attractive force between the nanoparticles can cause them to aggregate. Therefore, nanoparticles have to be dispersed by different methods, in order to utilize their unique material characteristics completely. This study aims to use the self-developed nanofluids synthesis system to produce a Cu-based nanofluid with good suspension stability and particle dispersion. Parameters such as peak c...

The interaction of copper oxide nanoparticles and copper ions and proteinase K from Tritirachium album Limber has been investigated employing UV spectroscopy and kinetics measurements. The aim of this study was to evaluate the effect of nanoparticles of CuO for proteinase K. In this paper we compare the effect of copper oxide nanoparticles with the effect of copper ions on proteinase K stabilit...

highly stabilized monodispersed silver nanoparticles (agnps) were synthesized by rhizopus stolonifer and the antifungal efficacy of silver nanoparticles (agnps) against candida sp. were studied. characterization of biosynthesized nanosilver was made by tem-eds and afm. minimum inhibitory concentration (mic) of biosynthesized agnps, amphotericin b, and fluconazole have been studied on pathogenic...
