Preparation of low-density superparamagnetic microspheres by coating glass microballoons with magnetite nanoparticles

Photoluminescent and superparamagnetic reduced graphene oxide–iron oxide quantum dots for dual-modality imaging, drug delivery and photothermal therapy

“…The diameter is, however, similar to that of the GQDs (51.9 nm) prepared by the same oxidation and hydrothermal treatment method in our group [40]. The MGQDs are identifiable in both the conventional and high resolution TEM images in dark contrast ( Figure 2A1-2A2, 3A) on the amorphous carbon film support due to the presence of high density IO (4.9 -5.2 g cm -3 for magnetite [41]) within the MGQDs as well as mass-thickness contrast, similar to the identification of IO on GO-IO reported in the literature [9]. Under HR-TEM, a region of magnetite (Fe 3 O 4 ) within an MGQD ( Figure 3B) can be identified by the (400) lattice spacing ~0.227 nm [42], with a similar region of magnetite in Figure 3C, 3D and 3E identifiable by the (220) lattice spacing of ~0.345 nm [42,43].…”

Preparation and microwave absorption properties of Ni–B alloy-coated Fe3O4 particles

“…Therefore, the demands to develop more economical electromagnetic wave absorbers with wider absorbing bandwidths and more effective absorbing are ever increasing [4,5].…”

Enhancement the Armor Shielding Properties of CF/epoxy Composite by Addition Nanoparticles of Magnetic Iron Oxide

“…Super -paramagnetic magnetite (Fe 3 O 4 ) were produced by a co-precipitation method from the aqueous solutions of FeCl 2 and FeCl 3 using a NaOH or NH 4 OH solutions [17][18].By applying the following standard procedures. First, prepare 0.11M FeCl 2 and 0.2 M FeCl 3 in 1 liter distilled water and put the solution in a reactor and stirred vigorously.…”
