Preparation, characterization and application of bilayer surfactant-stabilized ferrofluids

Fe 3O 4 magnetic nanoparticles (MNPs) were prepared by the coprecipitation of Fe 2+ and Fe 3+ using ammonium hydroxide (NH 4OH) as precipitating agent. Transmission electronic microscopy (TEM) showed that the particle-size is around 10 nm. X-ray powder diffraction (XRD) indicated the sole existence...
