Assembly of magnetite nanocrystals into spherical mesoporous aggregates with a 3-D wormhole-like pore structure
Byong Yong Yu,Seung-Yeop Kwak +1 more
TL;DR: In this article, a single iron precursor (iron(III) ethoxide) and an amphiphilic poly(ethylene oxide)-block-poly(propylene oxide)-poly(poly(methylene oxide) triblock copolymer (PEO100/PPO65/PEO 100) as a soft template were used to synthesize spherical mesoporous magnetite (Fe3O4) aggregates with wormhole-like pore structure.
Journal ArticleDOI
Stability and magnetic characterization of oleate-covered magnetite ferrofluids in different nonpolar carriers.
TL;DR: A thermodynamic analysis demonstrated that the observed stability of the suspensions in liquids with epsilon(r) < 5 is well correlated with the very low lyophobic attraction between the particles, and can be surmounted by thermal agitation, since the van der Waals attraction is negligible.

Magnetic Properties of Stable Dispersions of Subdomain Magnetite Particles
Robert Kaiser,G. Miskolczy +1 more
TL;DR: In this article, stable colloidal dispersions of subdomain-size magnetic particles have been prepared that retain their liquid characteristics in the presence of a magnetic field, correcting for the formation of a nonmagnetic surface mantle one unit cell thick.
