Application of magnetic nanoparticles for the removal of oil from oil-in-water emulsion: Regeneration/reuse of spent particles
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. …”

Application of Fe3O4 magnetite nanoparticles grafted in silica (SiO2) for oil recovery from oil in water emulsions
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. …”

A new design of solar tower system amplified with a thermoelectric unit to produce distilled water and power
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
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. …”
