Copper oxide (CuO) nanoparticles (NPs) were decorated on reduced graphene (rGO) through the effective synthetic route method. Powder X-ray diffraction, Fourier transform infrared, ultraviolet-visible absorption, and scanning electron microscopy techniques used to analyze chemical structure, functional groups, absorbance, morphology. Under visible light illumination, CuO/rGO nanocomposites have ...

INTRODUCTION Increased use of nanomaterials has raised concerns about the potential for undesirable human health and environmental effects. Releases into the air may occur and, therefore, the inhalation route is of specific interest. Here we tested copper oxide nanoparticles (CuO NPs) after repeated inhalation as hazard data for this material and exposure route is currently lacking for risk ass...

We report the synthesis of medicinal plant, Vernonia amygdalina Del. mediated green copper oxide nanoparticles (VeA-CuO NPs). The presence two absorbance maxima, λmax 1 and 2 at 436 nm 452 nm, respectively confirms a mixture biomolecules surface amalgamated CuO NPs with different morphological features. FT-IR spectra plant leaf extract VeA-CuO confirmed efficient role as capping stabilising age...

In this article, the oxidation of alcohols into carbonyl compounds was studied in oxygen atmospheres using a copper oxide on graphene (CuO@GO) nano composites catalyst, synthesized by wet chemistry method. CuO@GO were prepared from GO, and CuO NPs sol-gel The transformation aromatic corresponding good-to-high yields observed catalyst under an atmosphere. Synthesized confirmed FT-IR, XRD, XPS, T...

The Caspian trout is an endangered and quite vulnerable fish, considered for a natural protection program in the southern area of the Caspian Sea. Copper oxide nanoparticles (CuO-NPs) are toxic substances, which induce oxidative stress, not to mention other pathophysiological states. The toxicity of nanoparticles on fish needs more characterization for short- and long-term effects.  Thus, the p...

Wet chemistry was used to produce copper oxide nanoparticles (CuO NPs). The results indicated that most were bacillus-shaped and relatively uniform in size (less than 30 nm). effect of synthesized CuO NPs on wheat (Triticum aestivum L.) germination growth parameters studied compared bulk Cu. showed no significant difference obtained rate among all treatments. Bulk Cu additions significantly aff...

In this current research, we described an enhanced power conversion efficiency of dye sensitized solar cell (DSSC) and fabricated through Few Layered Graphene (FLG)/CuO nanocomposite synthesized by ultrasonic assisted synthesis (UAS) by varying of FLG (1, 2 and 3 wt%) ratio. The FLG/CuOnanocomposites characteristic features understood through various microscopic techniques such as FE-SEM and HR...

The fate of nanoparticles (NPs) in soil under relevant environmental conditions is still poorly understood. In this study, the mobility two metal-oxide (CuO and TiO2) contrasting agricultural soils was investigated water-saturated columns. transport TiO2 CuO-NPs were assessed six with three different textures (from sand to clay) contrasted organic matter (OM) contents for each texture. very low...

An aqueous extract of the shade-dried parts Asparagus aethiopicus L. and densiflorus (Kunth) Jessop was used to synthesize copper (CuO) nanoparticles (Cu NPs). UV-visible spectroscopy performed assess formation Cu NPs. Maximum absorbance obtained between 310–360 nm, confirming CuO NPs were effective against Pseudomonas aeruginosa (ATCC 27853), a gram-negative human pathogenic bacterium. The bac...
