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...

BACKGROUND CuO is one of the most important transition metal oxides due to its captivating properties. It is used in various technological applications such as high critical temperature superconductors, gas sensors, in photoconductive applications, and so on. Recently, it has been used as an antimicrobial agent against various bacterial species. Here we synthesized different sized CuO nanoparti...

Many studies have shown the effect of solution chemistry on the environmental behavior of metal-based nanoparticles (NPs), except CuO NPs. Here, we investigated the agglomeration, sedimentation, dissolution, and speciation of CuO NPs by varying pH, ionic strength, ionic valence, and natural organic matter (NOM). The results showed that as the pH moved away from 6, the size of CuO agglomerates d...

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...

Abstract Biosynthesis of antioxidant nanoparticles using plant extracts is a simple, rapid, environmentally friendly, and cost-effective approach. In this study, in vitro copper mixed oxide (CuO/Cu 2 O) were prepared from the alcoholic extract Phoenix Dactylifera L. different aqueous concentrations CuSO 4 ·5H O. The composition, crystallinity, morphology, particle size CuO/Cu O NPs tuned by inc...

Copper nanoparticles were fabricated by electro-reduction of CuSO4solution in the presence of cetyltrimethylammonium bromide (CTAB) cationic surfactant as an additive through potentiostatic method. The prepared copper nanoparticles were characterized by scanning electron microscopy (SEM) and electrochemical methods. The SEM images reveal that the nanoparticles with diameters at about 70 n...

Owing to its environment-friendly, biocompatible, non-toxic nature of nanoparticles attained from green plant extract, it has remarkable significance in the field nanotechnology towards effective biomedical application. This work reports synthesis copper oxide by means Cissus quadrangularis and Piper betle via green-synthesis route. The medicinal leaf extracts possessing phytochemicals such as ...

Copper is an essential microelement that indispensable for plant growth and development. The use of copper oxide nanoparticles (CuO NPs) in industry agriculture has also increased because their beneficial properties. However, excess amounts CuO NPs may negatively affect the monocotyledonous species, primarily through generation reactive oxygen which results oxidative stress. Despite increasingl...

BACKGROUND Copper oxide (CuO) nanoparticles have attracted huge attention due to catalytic, electric, optical, photonic, textile, nanofluid, and antibacterial activity depending on the size, shape, and neighboring medium. In the present paper, we synthesized CuO nanoparticles using gum karaya, a natural nontoxic hydrocolloid, by green technology and explored its potential antibacterial applicat...
