Abstract This work showed the preparation of Copper oxide nanoparticles (CuO NPs) from leaf extract Cinnamomum camphora (C.camphora) by a green synthetic method. To prepare CuO NPs, about 10 ml 0.01 M copper sulphate and 30 C.camphora were mixed heating for 60 min at temperature 80 °C. Various techniques such as x-ray diffraction analysis (XRD), Energy-dispersive spectroscopic (EDS), Fourier-tr...

Copper ions are an effective antimicrobial agent used to control Legionnaires' disease and Pontiac fever arising from institutional drinking water systems. Here, we present data on an alternative bactericidal agent, copper oxide nanoparticles (CuO-NPs), and its efficacy on Legionella pneumophila. In broth cultures, the CuO-NPs caused growth inhibition, which appeared to be concentration and exp...

A numerical simulation model for laminar flow of nanofluids in a pipe with constant heat flux on the wall was built to study the effect of the Reynolds number on convective heat transfer and pressure loss. The investigation was performed for hybrid nanofluids consisting of CuO-Cu nanoparticles and compared with CuO and Cu in which the nanoparticles have a spherical shape with size 50, 50, 50nm ...

A green synthesis of silver nanoparticles was done using a particular plant extract of Limonia acidissima. Silver nanoparticles were synthesised by the bioreduction of silver nitrate using different concentrations of plant extract, and UV–visible spectral analysis was carried out to confirm the formation of silver nanoparticles. The presence of various phytochemicals like flavonoids, steroids, ...

Supported copper oxide nanoparticles have attracted considerable attention as active and non-precious catalysts for many catalytic oxidation reactions. Herein, mesoporous xCuO-TiO2 nanotube catalysts were fabricated, and their activity and kinetics toward CO oxidation were studied. The morphology and structure of the prepared catalysts were systematically studied using SEM, TEM, EDS, EDX, XRD, ...
