A novel preparation and surface decorated approach for α-Fe nanoparticles by chemical vapor–liquid reaction at low temperature

Electrodeposition and magnetic properties of polypyrrole–Fe nanocomposites

“…These coercivities are larger by an order of magnitude than the coercivities of the nanocomposite consisting of iron oxide and polypyrrole [6]. However, such values for the coercivity of  Fe nanoparticles were reported elsewhere [16] and [17], supporting the X-ray diffraction data. As it is shown in Figure 3A-B, the coercive field in both parallel and perpendicular orientations is enhanced as the applied voltage (U 2 ) is increased.…”

“…Hence; the wide angle X-ray scattering (WAXS) data indicates the presence of alpha iron in polypyrrole-Fe nanocomposites. Recent investigations [16] on  Fe nanoparticles revealed the presence of a strong diffraction peak, characteristic to [1 1 0] reflections, which is absent in our case. This may indicate either a preferential orientation (texture) of Fe clusters or a distorted structure.…”

Solvothermal synthesis and characterization of cobalt microcrystals with hierarchical radial structure

“…Meanwhile, much attention has been paid to magnetic nanoparticles due to their novel physical and chemical properties [11][12][13]. Among magnetic metal nanoparticles, cobalt particles possess more outstanding magnetic properties and have potential applications in many areas including ferrofluids, biomedical systems, catalysts, optical and mechanic devices, high-density magnetic recording media [14][15][16][17][18][19][20][21][22][23].…”

Characteristics of Fe-Cr-Al Alloy Nanopowders Prepared by Electrical Wire Explosion Process under Liquid Media

“…[1][2][3][4] Therefore, metal nanopowders have been intensively investigated in various high performance applications, such as catalysts, ferrofluids, and microwave devices. [5][6][7] Various techniques have been developed to prepare metal nanopowders, such as gas-phase chemical reaction, 8) spray pyrolysis, 9) water-heating reaction, 10) laser ablation, 11) flame processing, 12) vapor deposition, 13) microwave plasma synthesis, 14) and the sol-gel method.…”
