The use of microwave-assisted synthesis (in water) α-Fe2O3 nanomaterials followed by their transformation onto iron oxide Fe3O4-γ-Fe2O3 hollow nanoparticles encoding well-defined sizes and shapes [nanorings (NRs) nanotubes (NTs)] is henceforth described. impact experimental variables such as concentration reactants, volume solvent employed, reaction times/temperatures during the shape-controlled revealed that key factor gated generation morphologically diverse was associated to initial...
The generation of topological magnetic vortex-domain structures in iron-oxide nanomaterials has promising applications biomedical scenarios, such as heat generators for hyperthermia treatments. In this report we describe alternative kinds magnetic-vortex nanoparticles, circular ${\mathrm{Fe}}_{3}{\mathrm{O}}_{4}$ nanodiscs (NDs), and dissect their heating properties by in-depth investigation shape size, stoichiometry, orientations, switching field ``${H}_{S}$'' behaviors, through experiments...
