    Self-healing performance of smart coatings modified with different corrosion inhibitors. حسب Habib, Sehrish

    منشور في 2020
    "…EIS measurements revealed the decent corrosion inhibition efficiency of these inhibitors in order of DDA>NMTU. As a result, they are a favorable solution for longer endurance of coated piping steel and decreased operation expense contributing to economic saves, materials reliability and safety…"

    Generation, performance evaluation and control design of single-phase differential-mode buck-boost current-source inverters حسب Darwish, Ahmed

    منشور في 2016
    "…Yet, the investigation, operation and implementation of these types of inverters have not been extensively discussed. As a drawback, the total dc side input current of a single-phase inverter consists of a dc component and an undesirable ac component. …"

    Emerging clay-aryl-gold nanohybrids for efficient electrocatalytic proton reduction حسب Jlassi, Khouloud

    منشور في 2018
    "…Both nanohybrids showed efficient electrochemical activity for HER in acidic condition (0.1 M H2SO4) with high current density up to −25 mA.cm−2 at −1 V and 0.148 mV onset. Negligible decreasing in current density and slight shift in onset was observed after 1000 cycles. …"

    Vertical zonation and functional diversity of fish assemblages revealed by ROV videos at oil platforms in The Gulf حسب Ben-Hamadou, Radhouan

    منشور في 2018
    "…These results suggest that the vertical zonation pattern does not change, or only changes slightly, on a daily basis. The mean centers of mass of the most abundant fish species did not overlap, likely due to potential competition or niche differences. …"

    Utilizing Recycled Polypropylene Fibers as Reinforcement for Concrete Beams حسب Bendjillali, Khadra

    منشور في 2020
    "…The various fiber content ratios tested in this investigation are 0.25, 0.5 and 1%. Based on the results of this study, the presence of recycled PP fibers in concrete decreases its workability; the addition of an adequate superplasticizer to the concrete mix becomes then necessary. …"
