Size-Controlled Synthesis of Magnetite Nanoparticles

Journal of the American Chemical Society, 2002
Monodisperse magnetite nanoparticles have been synthesized by high-temperature solution-phase reaction of Fe(acac)3 in phenyl ether with alcohol, oleic acid, and oleylamine. Seed-mediated growth is used to control Fe3O4 nanoparticle size, and variously sized nanoparticles from 3 to 20 nm have been produced.

Lanthanide(III)-Doped Magnetite Nanoparticles

Journal of the American Chemical Society, 2009
Nearly monodisperse lanthanide-doped magnetite nanoparticles were obtained by thermally decomposing a mixture of Fe(acac)(3) and Ln(acac)(3) (acac = acetylacetonate; Ln = Sm, Eu, Gd) in the presence of passivating surfactants. Magnetic studies revealed room-temperature ferromagnetic behaviors of these doped nanoparticles, distinctly different from ...

Physical and Chemical Properties of Magnetite and Magnetite-Polymer Nanoparticles and Their Colloidal Dispersions

Journal of Colloid and Interface Science, 1999
The properties of polymer-coated magnetite nanoparticles, which have the potential to be used as effective magnetic resonance contrast agents, have been studied. The magnetite particles were synthesized by using continuous synthesis in an aqueous solution.

Characterization of magnetite nanoparticles

2014 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings, 2014
This paper deals with the chemical preparation and magnetic characterization of nanoparticles of magnetite. A new hydrothermal synthesis of magnetite is adopted to prepare samples with different particle sizes and magnetic measurements are performed in two different laboratories adopting two different measurement methods.

Fortification of water kefir with magnetite nanoparticles

Food Research International, 2021
The aim of this work was to evaluate the suitability of incorporating Fe3O4 (magnetite, M) NPs into water kefir (wKef) beverages. Magnetite NPs were synthesized and coated with pectins (cM), and incorporated into wKef beverages obtained by fermentation of a muscovado sugar solution with wKef grains.

Organophosphorous functionalization of magnetite nanoparticles

Colloids and Surfaces B: Biointerfaces, 2013
In this work magnetite nanoparticles covered by gold and silver shell were obtained. Analyzed particles were modified by two kinds of organophosphorous compounds: 3-phosphonopropionic acid and 16-phosphonohexadecanoic acid. Enzyme immobilization on particles modified in such a way was tested.
