Nanostructures of metal oxides CuO, and TiO2 were prepared by the hydrothermal method. Also, CuO/TiO2 nanocomposites technique using an equal ratio 1:1 The properties compounds investigated through Field Emission Scanning Electron Microscopy FE-SEM, Transmission TEM, X-Ray Diffraction. images FE-SEM have confirmed that , nanoparticles structured as Nanoparticles, Spherical, CuO/ which mixed in ...

This paper shows the synthesis of CuO/Polystyrene(PS) nanocomposite superhydrophobic layer using spin coating method. The objective this study was to determine effect calcination temperature on contact angle, morphology, and energy gap CuO/PS thin layer. Preparation copper powder into oxide (CuO) nanoparticles method High Energy 3 Dimensional Milling (HEM-3D) for 20 hours. variations used were ...

Micron-size Ni-base alloy (NBA) powders were mixed with both 1.5 wt.% (hereinafter %) micron-size CeO2 (m-CeO2) and also 1.5% and 3.0% nano-size CeO2 (n- CeO2) powders. These mixtures were coated on low-carbon steel (Q235) by 2.0 kW CO2 laser cladding. The effects on the microstructures, phases and electrochemical corrosion of the coatings upon the addition of m- and n- CeO2 powders to NBA (m- ...

Herein, we described novel biogenic preparation of the CuO nanorods and its surface modification with l-alanine amino acid accelerated by microwave irradiation. The effect functionalized on physico-mechanical properties polyvinyl alcohol/carboxymethyl cellulose films were investigated through various characterization techniques. tensile strength was improved from 28.58 ± 0.73 to 43.40 0.93 MPa,...

The production of vanillin from lignin-derived vanillyl alcohol poses a great deal research interest because the availability renewable lignin in abundant quantities. In present study, series copper-doped ceria (CeO2) catalysts were prepared by modified template-assisted method, characterized various techniques, and explored for oxidation to with molecular oxygen as oxidant at normal atmospheri...

Composite coatings synthesized by different morphologies of CeO2 in supergravity devices are highly active in hydrogen evolution reactions (HERs). By adding CeO2 nanoflakes (CeO2 Nf) or CeO2 nanorods (CeO2 Nr), the change in the microstructures of composites becomes quite distinct. Moreover, most Ni–S alloys are attached on the surface of CeO2 and roughen it compare with pure CeO2. In order to ...

Abstract Commercial activities in the field of laundry services, cause problems water environment, hurt air quality, and were dangerous for life. Efforts that are now leading option most people using photocatalyst technology on semiconductor materials. MnO 2 is used as an auxiliary component development CuO-Fe O 3 to increase level degradation organic contaminants environment. This study aimed ...
