    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). …"

    Influence of changing casing groove parameters on the performance of centrifugal compressors near stall condition حسب Halawa, Taher

    منشور في 2016
    "…The casing grooves parameters considered are the groove cross section aspect ratio (the groove height to width ratio), groove location, and the number of grooves. Five groove aspect ratios were considered ranging from 0.2 to 1.8. …"

    Electrochemical oxidation of ammonia (NH4+/NH3) ON synthesized nickel-cobalt oxide catalyst حسب Almomani F.

    منشور في 2021
    "…The addition of Co to Ni–C enhanced ammonia oxidation reaction (AOR) by decreasing the oxidation peaks in the range of 0.23–0.56 V, increasing the reversible production of metal-hydroxides and generating power (Pgen) to sustain the reaction. …"

    Visible Light Photocatalytic Activity of Ag/WO3 Nanoparticles and its Antibacterial Activity Under Ambient Light and in The Dark حسب Maha, Matalkeh

    منشور في 2022
    "…Ultraviolet–visible spectra analysis observed a large redshift in the absorbing band edge and decreased bandgap energy from 2.6 to 2.1 eV. Photocatalytic analysis at different concentrations of 1% Ag/WO3 under visible light indicated a high degradation efficiency. …"
