The demand for new, thermally conducting light weight and anti-corrosive materials is tried by incorporating Copper Oxide (CuO) nano powder in polyethylene matrix material. A laboratory level electro deposition technique is adopted here to prepare Copper Oxide (CuO) nano particles. Their phase composition is confirmed with X-Ray diffraction peaks and verified with standard JCPDS file for Copper...

In this study CuO nano sheets were prepared using the cellulose extracted from green synthesis (cotton) as a novel me project. Structural properties were examined using X-Ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), and Ultra Violet (UV-Vis). The optimum copper oxide peak was at 2 theta 〖35.44〗^°corresponding to (1 ̅11) while for the cellulose was 〖22.8〗^°correspon...

Polymer composites of polyvinyl chloride, PVC, were loaded up with micro and nano PbO/CuO particles. The added percentage each by mass was 10 wt.%, 20 30 40 plus wt.% mixed composite (20 CuO + PbO). linear attenuation coefficients the investigated measured as a function gamma-ray energies going from 59.53 keV to 1408.01 utilizing standard radioactive point sources. To confirm validity these res...

By using CuO/graphene-oxide/CuO sandwich-like nanosheets as the building blocks, bulk nacre-inspired copper matrix nano-laminated composite reinforced by molecular-level dispersed and ordered reduced graphene oxide (rGO) with content as high as ∼45 vol% was fabricated via a combined process of assembly, reduction and consolidation. Thanks to nanoconfinement effect, reinforcing effect, as well a...

CuO nanosheets, Cr-doped CuO nanosheets, and Cr-doped CuO nanorods were prepared by heating a slurry containing Cu-hydroxide/Cr-hydroxide. Their responses to 100 ppm NO(2), C(2)H(5)OH, NH(3), trimethylamine, C(3)H(8), and CO were measured. For 2.2 at% Cr-doped CuO nanorods, the response (R(a)/R(g), R(a): resistance in air, R(g): resistance in gas) to 100 ppm NO(2) was 134.2 at 250 °C, which was...

Novel graphitic carbon nitride/CuO (g-C₃N₄/CuO) nanocomposite was synthesized through a facile precipitation method. Due to the strong ion-dipole interaction between copper ions and nitrogen atoms of g-C₃N₄, CuO nanorods (length 200-300 nm, diameter 5-10 nm) were directly grown on g-C₃N₄, forming a g-C₃N₄/CuO nanocomposite, which was confirmed via X-ray diffraction (XRD), transmission electron ...

Optical and nonlinear-optical properties of negativeindex nanocomposite as well as the feasibility of a design of novel photonic microdevices and all-optical data processing chips are numerically simulated. Keywords—Numerical simulation, nano materials and nanostructures, negative-index metamaterials, nanophotonics, nano and micro devices, all-optical switches, optical frequency narrow-band fil...

conclusions increasing the cu nanoparticles in bioactive glass samples leads to the release of cu2+, which has a positive effect on the antibacterial mechanism, as well as decreasing the cultured staphylococcus colonies found on the bioglasses. therefore, it seems that the nanocomposite/bioglass of cuo is a promising option for aerobic bacterial inhibitor systems in common bone implant infectio...

In the present research, an efficient process for the synthesis of propargylamine derivatives catalyzed by a novel nanocomposite of CuO/MnO2 is reported. CuO/MnO2 nano-catalyst was synthesized by the co-precipitation process and characterized by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), X-ray diffraction(XRD), ICP-OES and BET surface area an...
