    A MEASUREMENT CAMPAIGN TO INVESTIGATE THE EFFECT OF USING SOFT RAILPADS ON GROUND-BORNE VIBRATIONS FROM UNDERGROUND RAILWAYS by Alsharo, Anas

    Published 2023
    “…Insertion Gains were calculated from the acquired data, and the findings demonstrated that using the soft resilient railpads decreased the vibration level on the free surface by around 10 dB for the majority of frequencies in the range of 40-200 Hz.…”

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

    Published 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 by Halawa, Taher

    Published 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 by Almomani F.

    Published 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. …”
