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...

this study aimed to investigate the effects of tow nanoparticles (nps) on the absorption,accumulation, reproduction of the eisenia fetida. a 4×2×2 factorial experiment in a randomized completeblock design with three replications was conducted. the factors included in the experiment are the content ofnps at four levels (0, 0.4, 0.8, and 1.2gr/kg weight of substrate), the type of nps at two level...

This study elaborates the consequences of oxidative stress caused by copper oxide (CuO) and titanium dioxide (TiO2) nanoparticles (NPs) in Brassica juncea. Effect of these two NPs on plant physiology, reactive oxygen scavenging enzyme system (ascorbate peroxidase, catalase, superoxide dismutase), proline content and lipid peroxidation has been estimated in leaves as well as root tissues. Bioacc...

Study of nanofluids is important for different types of heat transfer management systems. Cupric oxide nanoparticles (CuO NPs) were prepared by the chemical route and different nanofluid samples of CuO NPs dispersed in PVA in different concentrations were prepared using ultrasonication. The apparatus acoustic particle sizer (APS-100) was used to make high precision measurements of the ultrasoni...

in the present study, tenorite (cuo) nanoparticles have been assayed for their catalytic properties. the decontamination reaction of chloro ethyl ethyl sulfide (cees) as an surrogate of sulfur mustard simulant have been accomplished on the surface of cuo nps with different weight ratios at ambient temperature and monitored by gas chromatography equipped with flame ionization detector (gc-fid) a...

In this paper, chemically synthesized copper oxide nanoparticles (CuO-NPs), were employed for two processes: one is photocatalytic degradation and second one adsorption for the sorption of safranine (SA) dye in an aqueous medium at pH = 12.01. The optimized analytes amount (nano-adsorbent = 0.10 g, conc. range of SA dye 56.13 ppm to 154.37 ppm, pH = 12.01, temperature 303 K) reached to equilibr...

In nanotoxicology, the capacity of nanoparticles of the same composition but different shape to induce cytotoxicity and genotoxicity is largely unknown. A series of cytotoxic and genotoxic responses following in vitro exposure to differently shaped CuO nanoparticles (CuO NPs, mass concentrations from 0.1 to 100 μg/ml) were assessed in murine macrophages RAW 264.7 and in peripheral whole blood f...

Nanotechnologies research has become a significant priority worldwide. Many engineered nano-sized materials have been increasingly used in consumer products. But the adverse effects of these nanoparticles on the environment and organisms have recently drawn much attention. The present study investigated the effects of different concentrations of copper oxide nanoparticles (CuO NPs) on the sheep...

With the growing availability and use of copper-based nanomaterials (Cu-NMs), there is increasing concern regarding their release and potential impact on the environment. In this study, the short-term (≤5 d) aging profile and the long-term (135 d) speciation of dissolved Cu, copper oxide, and copper sulfide nanoparticles (CuO-NPs and CuS-NPs) were investigated in five different soils using X-ra...
