Synthesis of silanized maghemite nanoparticles onto reduced graphene sheets composites [PDF]

, 2014
Novel gamma-Fe2O3@APTES@rGO composites are successfully synthesized by using graphene oxide and silanized maghemite nanoparticles. Graphene oxide and maghemite were obtained by Hummers and Massart methods, respectively.

Improved biocompatibility and efficient labeling of neural stem cells with poly(L-lysine)-coated maghemite nanoparticles

Beilstein Journal of Nanotechnology, 2016
Background: Cell tracking is a powerful tool to understand cellular migration, dynamics, homing and function of stem cell transplants. Nanoparticles represent possible stem cell tracers, but they differ in cellular uptake and side effects.

How temperature determines formation of maghemite nanoparticles [PDF]

, 2020
a b s t r a c t We report on the formation of polymer-stabilized superparamagnetic single-core and multi-core maghemite nanoparticles. The particle formation was carried out by coprecipitation of Fe(II) and Fe(III) sulfate in a continuous aqueous process

Some Canadian occurrences of maghemite

, 1970
Maghemite has been found in samples from the lateritic 'buckshot ' ore bands of the Steep Rock Lake iron deposits. Partial chemical analysis of a magnetic concentrate gave 84. 42 per cent Fe 2o3, 0 . 36 per cent FeO, and 2.8 per cent H 2o. The maghemite has a cell edge of 8 .33 + . 01 A, and an average Vickers microhardness of 920.

Preparation of Monodisperse Iron Oxide Nanoparticles via the Synthesis and Decomposition of Iron Fatty Acid Complexes

Nanoscale Research Letters, 2009
Iron fatty acid complexes (IFACs) are prepared via the dissolution of porous hematite powder in hot unsaturated fatty acid. The IFACs are then decomposed in five different organic solvents under reflux conditions in the presence of the respective fatty ...
