    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. …"

    Impact of trace noble metals on the catalytic performance of LaNiMgO towards methane dry reforming حسب Mohamed, Assem T.

    منشور في 2024
    "…In addition, the presence of noble metals at the Ni surface afforded a high density of adsorbed oxygen species, which enhanced coke gasification and consequently decreased the extent of deactivation of the catalysts by coke formation. …"

    Tailoring the defects of sub-100 nm multipodal titanium nitride/oxynitride nanotubes for efficient water splitting performance حسب Eid, Kamel

    منشور في 2021
    "…These defects decreased the bandgap energy to 2.4 eV, increased visible-light response, and enhanced the incident photon-to-current collection efficiency (IPCE) and the photocurrent density of TiONxNTs by nearly 8 times compared with TiO2NTs, besides a quick carrier diffusion at the nanotube/electrolyte interface. …"

    Functionalization of silica-coated magnetic nanoparticles as powerful demulsifier to recover oil from oil-in-water emulsion حسب Elmobarak W.F.

    منشور في 2021
    "…The Fe–Si-MNP exhibited excellent %Soil, reliable stability, and high magnetization values ranging between 46.1 and 80.2 emu/g. adding a 5 nm silica layer on the surface of the Fe–Si-MNP (i.e., Fe–Si-1) protected them from oxidation conditions, extended their service life, and achieved a %Soil of ∼96.3%. …"
