  1. The monodisperse Fe2O3 particles were produced using a spinning top aerosol generator with subsequent online heat degradation of the particles in a tube furnace at 800°C. The aerodynamic characterization of the particles was continuously monitored with an aerodynamic particle sizer (Type APS33, TSI Inc.) and by low-angle forward-scattering optical aerosol spectrometry.
