    Enhancing the corrosion resistance of reinforcing steel under aggressive operational conditions using behentrimonium chloride حسب A. Bahgat Radwan (9631720)

    منشور في 2019
    "…Herein, the inhibition efficiency of a new corrosion inhibitor, behentrimonium chloride (BTC, C25H54ClN), is explored in a simulated-concrete pore solution (SCP) with 3.5 wt.% NaCl at different pH using electrochemical impedance spectroscopy (EIS) and polarization methods. …"

    Enhanced thermoelectric properties of Bi<sub>2</sub>Te<sub>2.55</sub>Se<sub>0.45</sub> nanocomposites using eco-friendly Eocene Midra Shale palygorskite nanofillers: A sustainable... حسب Farah M. El-Makaty (14157090)

    منشور في 2025
    "…The EMS was obtained from one of Qatar’s substantial hydrocarbon reservoirs and mixed with the Bi2Te2.55Se0.45 alloy using ball-milling and hot-pressing techniques. Different wt% of EMS (0.025, 0.05, 0.1, 0.5, and 1) were considered. …"

    Corrosion Evaluation of 316L Stainless Steel Exposed to CNT-Water Nanofluid حسب Dana Abdeen (18147583)

    منشور في 2019
    "…Adsorption isotherm for CNTs adsorption on the surface of the metal and some thermodynamic properties of adsorption were found to help in proposing a mechanism for CNTs corrosion inhibition. It was observed that the SS tested in CNTs nanofluids presented low corrosion rates, which were comparable to those for tap water and lower than those for 3.5 wt.% NaCl solutions. …"

    Part II.: Dissimilar friction stir welding of nickel titanium shape memory alloy to stainless steel – microstructure, mechanical and corrosion behavior حسب Parker West (17268946)

    منشور في 2021
    "…Importantly, the transformation temperatures of NiTi, measured by differential scanning calorimetry (DSC) from different weld zones, varied by no more than 4 °C. Corrosion properties of the weld zone investigated in 3.5 wt. % NaCl solution showed moderately inferior corrosion resistance of dissimilar weld, compared to individual base metals, as characterized by the surface film impedance and corrosion current density. …"
