NANO HIGHLIGHT Synthesis and Classification of Monodisperse Magnetic Nanoparticles NSF NIRT Grant 0304649

antiferromagnetic materials) have many promising industrial and biomedical applications such as catalysis, magnetocooling, optical and recording devices, purification of enzymes and other biological materials, and water purification devices. Most of the conventional methods for the synthesis of magnetic nanoparticles are rather complex, usually involving several steps; efforts have been made to establish direct preparation routes of these magnetic particles. In this project, γ-phase iron oxide nanoparticles were synthesized using a flame aerosol reactor. The effects of flame temperature profile and sampling conditions have been investigated on the morphology and magnetic properties of synthesized maghemite nanoparticles. The particle size and magnetic properties of the powders can be controlled b
