Size-controlled synthesis of Fe3O4 magnetic nanoparticles via an alternating magnetic field and ultrasonic-assisted chemical co-precipitation

Fe3O4-PEI Nanocomposites for Magnetic Harvesting of Chlorella vulgaris, Chlorella ellipsoidea, Microcystis aeruginosa, and Auxenochlorella protothecoides

“…The reaction yield can be increased by vigorous stirring. The grain size and magnetic properties of the nanoparticles can be adjusted by controlling the reaction conditions [ 56 , 57 ]. Furthermore, the addition of different oxidizing and chelating agents, e.g., surfactants, saccharides, and polymers, is possible, which can influence the characteristic properties of the prepared nanoparticles [ 58 ].…”

Pharmaceuticals removal by synergistic adsorption and S-scheme photocatalysis using nano-CeO2-coupled Fe3O4 on a CTAB matrix and investigation of the nanocomposite's antibacterial and antibiofilm activities: intrinsic degradation mechanism

“…Compared to the biological and physical methods of synthesis, chemical methods are relatively reproducible and costeffective. 17 The ultrasonication process during synthesis involves uniform nucleation and increased surface area and plays a vital role in enhancing photocatalytic and antibacterial activities. 18 The present contribution is focused on the adsorptive/ photocatalytic removal of tetracycline from an aqueous solution using Fe 3 O 4 -CeO 2 -CTAB nanocomposites (NCs).…”

Functionalized iron oxide nanoparticles: synthesis through ultrasonic-assisted co-precipitation and performance as hyperthermic agents for biomedical applications

“…IONPs generated localized heat energy under the alternating magnetic field. This increased energy forms the basis of the application of magnetic induction heating properties in cancer therapy [ 24 , 25 , 26 , 27 ]. Next, the influences of viscous carriers (ethanol and water) and the magnetic field power (1 and 0.5 kW) with a frequency of 142 kHz on the heating profile of the synthesized IONPs were investigated.…”

“…The temperature elevated linearly with time and then the increase in temperature decelerated gradually until reaching the saturation stage. Thereafter, the temperature did not increase any further due to the occurrence of thermal equilibrium which is defined as a point at which heating rate equals cooling rate [ 24 ]. The specimens became heated faster, and the heating rate rose with the power increase ( Figure 9 ).…”
