This report mainly focuses on the investigation of morphological, optical, and electrical properties of Al2O3/ZnO nanolaminates regulated by varying bilayer thicknesses. The growth mechanism of nanolaminates based on atomic layer deposition and Al penetration into ZnO layer are proposed. The surface roughness of Al2O3/ZnO nanolaminates can be controlled due to the smooth effect of interposed Al...

In this paper, CuO-ZnO nanocomposite was synthesized and its photocatalytic dye degradation ability from colored wastewater was studied. Basic Red 18 (BR18) and Basic Violet 16 (BV16) were used as model dyes. The characteristics of CuO-ZnO of were investigated using Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscope (SEM) and X-ray diffraction (XRD). Photocatalytic dy...

Microstructural characteristics of various real Cu/ZnO/Al2O3 catalysts for methanol steam reforming (MSR) were investigated by in situ X-ray diffraction (XRD), in situ X-ray absorption spectroscopy (XAS), temperature programmed reduction (TPR) and electron microscopy (TEM). Structure–activity correlations of binary Cu/ZnO model catalysts were compared to microstructural properties of the ternar...

BACKGROUND The release of heavy metal-containing nanoparticles (NP) into the environment may be harmful to the efficacy of beneficial microbes that function in element cycling, pollutant degradation and plant growth. Nanoparticles of Ag, CuO and ZnO are of interest as antimicrobials against pathogenic bacteria. We demonstrate here their antimicrobial activity against the beneficial soil microbe...

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 complete block design with three replications was conducted. The factors included in the experiment are the content of NPs at four levels (0, 0.4, 0.8, and 1.2gr/kg weight of substrate), the type of NPs at two le...

In the present work, ZnO/CuO composite nanostructures have been grown on uorine doped tin oxide coated glass substrate by aqueous chemical growth method. To observe the e ect of post growth annealing (500 ◦C, 1 min) on the structural properties of ZnO nanorods scanning electron microscope and X-ray di raction techniques have been utilized. SEM images of post growth annealed (post growth anneale...

Fuel cell powered electric cars using on-board methanol or hydrocarbon reforming to produce a hydrogenrich gas represent a low-emissions alternative to gasoline internal combustion engines (ICE) with well-towheel efficiencies of 17 %. For the overall methanol process, a simplified model of the reaction network consisting of the total oxidation of methanol, the reverse water-gas shift reaction, ...

We report low-temperature solution-processed p-CuO nanorods (NRs)/n-ZnO NRs heterojunction light emitting diode (LED), exploiting the native point defects of ZnO NRs. ZnO NRs were synthesized at 90 °C by using hydrothermal method while CuO NRs were synthesized at 100 °C by using microwave reaction system. The electrical properties of newly synthesized CuO NRs revealed a promising p-type nature ...
