The magnetic metals were also prepared by a method [25] based on the rapid expansion of supercritical fluid solutions (RESS) coupled with chemical reduction to produce nickel, cobalt, iron, and iron oxide nanopartides of reasonably narrow size distribution. Under the protection of a polymer stabilization agent, the largely amorphous metal nanopartides form stable suspensions in room-temperature solvents.

The maximum SAR calculated for pure Fe- and Co-based systems can be significantly higher compared to iron oxide nanopartides [204, 284, 285]. However, the main concern for use for in vivo applications is their potential toxicity assodated with the release of cytotoxic Co ions.

A typical TEM image of hybrid magnetic nanowires is shown in Figures 50(a) and 50(b). As the polymeric parts lack enough contrast in the TEM characterization, they appear transparent. When iron oxide nanopartides are formed, they...

All these technological and medical apvplications require that the nanoparticles are superparamagnetic with size smaller than 20 nm and the overall particle size distribution is narrow so that the part ides have uniform physical and chemical properties. In the last years, various methods for the preparation of such particles have been developed and optimized. High-quality monodisperse iron oxide nanopartides with high crystalline and narrow size distribution have been prepared by a high-temperature organic phase decomposition method. 

A simple and economical method to achieve stable water-soluble iron oxide nanopartides is based on dispersions in an ionic liquid containing acrylic add anion. Distinct particles were synthesized by an organic phase decomposition method. The synthesis of magnetite nanopartides in our laboratories was carried out only by simple precipitation of ferrous salts in alkaline aqueous solutions at low temperature. It was found that the ionic liquid can be used as solvent and stabilizer to effidently tune the particle growth and prevent nanopartide aggregation (Zhai et al., 2009). 

As it has been shown in Section 7.3, the longitudinal coefficients of elasticity Cjj and viscosity and shear viscosity coefficients 7/44 of the nanocomposite polymeric materials under study almost always decrease with increasing the concentration of nanopartides. The only exception was for the nanocomposite material with the iron oxide nanopartides. In this case, the value of Cjj decreased with increasing the concentration nanopartides, passed through a minimum at their concentration of 15%, and increased again. As for the shear elastic coefficient its value exhibited nonmonotonic variation depending on the concentration of the nanopartides in all cases.
