    Application of Fe3O4 magnetite nanoparticles grafted in silica (SiO2) for oil recovery from oil in water emulsions by Elmobarak W.F.

    Published 2021
    “…Using an MDdose as low as 10 mg/L attained a %ηdem in the range of 93%–94.3% for O/W mixtures with Coil < 2000 mg/L, which slightly decreased to ∼90% for higher concentrations. …”

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

    Published 2021
    “…This study presents an innovative approach for the preparation of Fe3O4 nanoparticles covered with SiO2 shell (denoted as Fe–Si-MNP), which were used to recover oil recovery from oil-in-water emulsion (O/W-emul). The Fe–Si-MNP were prepared with differing silica layer thicknesses (5 nm [Fe–Si-1], 8 nm [Fe–Si-2], 10 nm [Fe–Si-3], and 15 nm [Fe–Si-4]) and tested for the percentage of oil separation (%Soil) under different dosages (DMNP), oil concentration (Doil), surfactant dosages (Dsur), and pH. …”

    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. …”

    Bioactive PCL matrices with a range of structural & rheological properties by Douglas, P.

    Published 2016
    “…Increased loading of PEG to 25% (w/w) caused a 10-fold increase in the melt flow index, a similar increase in the elongational viscosity, and a contact angle decrease of 10°, indicating that the resultant fluid was becoming more Newtonian. …”

    Impact of combined oil-in-water emulsions and particulate suspensions on ceramic membrane fouling and permeability recovery by Abdalla M.

    Published 2019
    “…The addition of 1500 mg·L−1 of bentonite to a 10 vol.% emulsion resulted in a permeability decrease of 3.55 times over that recorded for the emulsion, and 8–36 times lower than that of the bentonite suspension. …”
