“…In this case, liquid phase reaction mechanism have dominated. So, the nucleation and growth were accelerated and completed within short time which is indicate that the described technique is suitable for rapid formation of nanoparticles with good crystallinity [27]. The structural parameters are summarized in Table I which reveals that the size of MgFe 2 O 4 is sensitive to the temperature of formation.…”

“…Some of this solution based methods have complicated steps and unfortunate grain growth with necking of particles can usually occur during the calcination step or post-annealing process in atmospheric environment [27]. In case of ultrasonic spray pyrolysis, a nanoscale particles can be yielded in the desired size regime ranging from below the superparamagnetic limit to the monodomain limit with various advantage such as good crystallinity, chemical homogeneity, high purity, short reaction time and available for mass production [28][29][30][31][32][33].…”

Co-Ti and Ru-Ti substituted barium ferrite nanocrystalline particles BaFe 12-2x ) were prepared by ball milling method, and their magnetic properties and their temperature dependencies were studied. The zero-field-cooled (ZFC) and field-cooled (FC) processes were recorded at low magnetic fields and the ZFC curves displayed a broad peak at a temperature T M . In all samples under investigation, a clear irreversibility between the ZFC and FC curves was observed below room temperature, and this irreversibility disappeared above room temperature. These results were discussed within the framework of random particle assembly model and associated with the magnetic domain wall motion. The resistivity data show some kind of a transition from insulator to perfect insulator around M T . At 2 K, the saturation magnetization slightly decreased and the coercivity dropped dramatically with increasing the Co-Ti concentration x. With Ru-Ti substitution, the 2 saturation magnetization showed small variations, while the coercivity decreased monotonically, recording a reduction of about 73% at x = 0.6. These results were discussed in light of the single ion anisotropy model and the cationic distributions based on previously reported neutron diffraction data for the CoTi substituted system, and the results of our Mössbauer spectroscopy data for the RuTi substituted system.

“…Recent years a surge has been seen in magnetic nanoparticles applications in several areas such as microelectronics, optoelectronics, physics, chemistry, biology, and materials science, but particularly in biomedical field [1][2][3][4][5][6][7][8][9][10]. Several sorts of magnetic nanoparticles have been widely investigated for biomedical applications, among which iron oxide-based magnetic nanoparticles are very promising candidates due to their unique features like biocompatibility, large surface area and superparamagnetic behavior that make them an ideal tool for cell separation, magnetic resonance imaging (MRI) [11][12], cancer treatment by hyperthermia [13][14][15] drug delivery systems (DDS) [16,17].…”

recent years a surge has been seen in magnetic nanoparticles applications in several areas, particularly in biomedical field. the promising features of the iron oxide based magnetic nanoparticles make them an ideal tool for mri contrast agents, hyperthermia, and as drug delivery systems (DDs). the present paper describes the design and synthesis of Bao·6Fe 2 o 3 nanostructured meso-macroporous spherical aggregates by sol-gel method via spray drying technique. the obtained spherical aggregates have micrometric size, which let them to be carried by the bloodstream to a specific site where the drug is going to be release. the obtained hierarchical porous structure combined with the interconnected mesoporosity allow the body fluids to be transport through the aggregates; and the macroporosity allows the load of large molecules, like peptides. Furthermore, the structural and morphological characterization of the obtained Bao·6Fe 2 o 3 aggregates were carried out using X-ray diffraction and field emission scanning electron microscopy. keywords: nest-like morphology, hierarchical porous structure, drug delivery, barium hexaferrite.
