“…Most other authors report the formation of spherical particles. [33] As there are only a few reports on the fabrication of g-Fe 2 O 3 particles with diameters comparable to those presented here, [34][35][36][37] our approach is a simple and therefore technologically interesting alternative for the fabrication of welldefined g-Fe 2 O 3 nanoparticles, provided that magnetite formation can be suppressed better than is possible at the moment.…”

We have recently shown that the hydrated ionic liquid tetrabutylammonium hydroxide (TBAH) is an efficient ionic liquid precursor (ILP) for the fabrication of ZnO/carbohydrate materials (D. Mumalo-Djokic, W. B. Stern, A. Taubert, Cryst. Growth Des. 2008, 8, 330). The current paper shows that ZnO is just one example out of the large group of technologically important metal (hydr)oxides that can be made using TBAH. Simply by using different metal acetates as precursors in TBAH, it is possible to make a wide variety of metal (hydr)oxides with well-defined size, morphology, and chemical composition. It is also possible to dope metal oxide particles or to synthesize mixed metal oxide particles, and therefore to control properties like magnetism.

“…Figure 4 shows the X-ray di ractograms of the magnetite nanocomposites loaded with di erent amounts of GO. Two reections are distinguished in these samples (at 2Θ 30.36°a nd 35.6°) that belong to the (220) and (311) lattice planes of the cubic magnetite crystal structure [54]. Since the dominant mass in all samples belongs to the MNP phase, the respective peak intensities do not show much variation with the composition.…”

Nanostructured composite dispersions containing magnetic nanoparticles (MNPs) and graphene oxide (GO) lamellae have been prepared by a simple and easily scalable room temperature procedure. We show that, owing to the enormous surface area and negative surface charge developed in aqueous GO suspensions, large amounts of positively charged MNPs can be electrostatically attached to the layered host. is procedure is superior to many previous synthesis pathways because it exploits the chargeregulated adhesion of naked MNPs to GO resulting in the formation of stable and uniform nanocomposite materials in a wide composition range without any preliminary functionalization steps or harsh conditions that may lead to chemical degradation of the graphene-based nanosheets.

We have investigated the magnetic behavior of magnetite nanoparticles covered by the 11-mercaptoundecanoic acid around magnetite core prepared by a standard co-precipitation method. The particles show superparamagnetic behavior at room temperature, with transition to a blocked state at blocking temperature 91 K estimated from zero eld cooled and eld cooled at 500 Oe experiment. The hysteresis loop measured at 293 K showed magnetization 32.8 emu/g at 50 kOe without any coercivity. The mean particle size (7.1 nm) was determined by tting a magnetization curve obtained at 295 K assuming a lognormal size distribution.
