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

    Published 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%. …”

    Effect of outdoor temperature on the power-conversion efficiency of newly synthesized organic photosensitizer based dye-sensitized solar cells by Mehmood U.

    Published 2018
    “…The results indicate that DSSC shows power conversion efficiency of 2.58% at 25 °C under air mass (AM) 1.5 G illumination at 100 mW/cm2. It has also been found out that the efficiency of DSSCs drops with the rise of temperature. …”
