    Facile Electrochemical Synthesis of Highly Efficient Copper-Cobalt Oxide Nanostructures for Oxygen Evolution Reactions حسب Nath, Narayan Chandra Deb

    منشور في 2020
    "…An optimized nanopetal structure of CuxCo3-xO4 (x = 0.95, annealed at 200 °C) shows a considerably high Faradaic efficiency (∼93%) with a remarkably low overpotential (∼230 mV) at a benchmark current density (J) of 10 mA cm-2; at the same J in an alkaline solution (1 M KOH) for OER, it also exhibits high durability (up to 100 h). …"

    Synthesis and properties of HA/ZnO/CNT nanocomposite حسب Ding M.

    منشور في 2018
    "…The goal of this study was to examine the tribomechanical properties of hydroxyapatite (HA)/ZnO and HA/ZnO/CNT composite ceramics (carbon nanotubes; with different ratios 0.5 wt%, 1.0 wt%, and 1.5 wt%). The composites were synthesized using the hydrothermal method in an autoclave. …"
