    Application of magnetic nanoparticles for the removal of oil from oil-in-water emulsion: Regeneration/reuse of spent particles by Elmobarak W.F.

    Published 2021
    “…Up to 98.6% of the %Roil was attained for Coil in the range from 0 to 800 mg/L using only a DMNP of 10 mg/L. A lower DMNP of 5 mg/L recovered up to 55.6% of the oil, while increasing the DMNP > 50 mg/L did not significantly affect the %ηdem nor the %Roil. …”

    A new design of solar tower system amplified with a thermoelectric unit to produce distilled water and power by Khanmohammadi, Shoaib

    Published 2021
    “…Additionally, the results show that employing TEGs in the primary system leads to the net output power, energy, and exergy efficiencies increment about 941 kW, 3.7%, and 5.28%, respectively. Based on the parametric analysis with an increasing inlet temperature of the gas turbine, the net output power, energy, and exergy efficiencies, and volume flow rate of the freshwater increase. …”

    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%. …”
