    Polyaniline/Polystyrene Blends: In-Depth Analysis of the Effect of Sulfonic Acid Dopant Concentration on AC Conductivity Using Broadband Dielectric Spectroscopy حسب Noora Al-Thani (14147829)

    منشور في 2018
    "…Increasing CSA resulted in a decrease in the AC conductivity of the blends. This behaviour was explained in terms of the availability of a lone pair of electrons of the NH groups in the polyaniline, which are typically attacked by the electron-withdrawing sulfonic acid groups of CSA. …"

    Insights on the effect of water content in carburizing gas mixtures on the metal dusting corrosion of iron حسب El Tayeb Bentria (9904024)

    منشور في 2022
    "…At later stage, the formation of oxide scale leads to an elevated concentration of H<sub>2</sub>O/OH molecules on the surface due to the decrease in Fe affinity to dissociate water. This results into blocking the Fe catalytic sites leading to lower C and O diffusion to the bulk of the sample.…"

    A comparison of metals in sediments and water in the River Nahr-Ibrahim, Lebanon حسب Korfali, Samira Ibrahim

    منشور في 2003
    "…Data revealed a drop in metal concentrations (Zn, Cu, Pb, Cd) in sediments at quarry site after its closure. The decrease in precipitation rate, lowering the level of water and the dilution of industrial discharges and decrease in water pH led most probably to the desorption of metals from sediments into the water.…"
