Magnetic behavior of Fe3O4 nanostructure fabricated by template method

Fe3O4/PS magnetic nanoparticles: Synthesis, characterization and their application as sorbents of oil from waste water

“…There are numerous magnetic materials, in which the Fe 3 O 4 is of great interest due to its non-toxic characteristic, low cost and strong magnetic response. At present, there are many methods for the synthesis of Fe 3 O 4 such as co-precipitation method [28][29], solution casting technique [30], template method [31] and so on [32]. In this work, we reported a kind of recyclable, environmentally friendly and highly selective oil-absorbent materials based on core-shell structure for removing oils from water surface.…”

Study of Faraday effect on Co1-xZnxFe2O4 nanoferrofluids

“…During the transition of electrons between degenerate states, rotation of plane of polarization is accompanied by the development of an ellipticity of the originally polarized light [22]. Also, it was reported that Faraday rotation can be enhanced due to crystal field transitions and intervalence charge transfer transitions between neighboring ions [22,23]. Varying the occupancy of tetrahedral and octahedral sites changes the Faraday rotation.…”

Magnetic Iron Oxide Nanoparticles for Biomedical Applications

“…Certain inorganic coatings, such as gold [96], alumina [97] or silica [98] also allow improvement of the stability in aqueous dispersion, as well as fictionalization of the magnetic particles for various biomedical applications. By ensuring simultaneously chemical stabilization on a broad pH range and bio compatibility, silica represents an ideal choice for obtaining stable ferrofluids [99,100].…”
