Preparation of monodispersed hybrid nanospheres with high magnetite content from uniform Fe3O4 clusters

Preparation and magnetic properties of Fe3O4 microparticles with adjustable size and morphology

“…The exploration of the methods for synthesizing magnetic microcrystals with desired morphology and size has been of scientific and technological interest [7]. Employing various methods, the Fe 3 O 4 with different morphologies have been successfully synthesized, such as spheres [8][9][10][11], octahedrons [12][13][14][15][16][17], cubes [18,7], tetrakaidecahedrons [19], wires [20,21], fractals [22], dendrites [23], hollow structures [24], urchin-like structures [5], nanosheets [1,25], and nanoprisms [26]. However, fine shape control of Fe 3 O 4 microparticles through a simple synthesis process with good size and shape-dependent properties remains a difficult task [27].…”

Magnetic CMP microspheres: multifunctional poly(phenylene ethynylene) frameworks with covalently built-in Fe3O4 nanocrystals exhibiting pronounced sensitivity for acetaminophen microdetection

“…It reveals a saturation magnetization of $6.5 emu g À1 , which can be used to calculate the magnetic content, giving about 8.8%, compared with 72.8 emu g À1 for pure Fe 3 O 4 nanocrystals. 20 It is a little more than the result evaluated from the thermolysis curves (7.4 wt%). The possible reason for this is that the residual Pd catalysts were included in the calculation of magnetic content when the data of weight loss were used, leading to a slight error.…”

Encapsulation of Inorganic Nanoparticles by Miniemulsion Polymerization

“…On the other hand, magnetite/polystyrene latexes with narrow size distribution and high magnetite content were also prepared by a hybrid miniemulsion polymerization process containing binary droplets [102][103][104]. First of all, magnetite nanoparticles modified with oleic acid were synthesized and dispersed in octane.…”
