      abstract     = {The controlled synthesis of superparamagnetic iron oxide
                      nanoparticles is crucial for a variety of biomedical
                      applications. Among different synthesis routes thermal
                      precursor decomposition methods are the most versatile,
                      yielding monodisperse nanoparticles on the multi-gram scale.
                      Recent in situ kinetic studies of the nucleation and growth
                      processes during thermal decomposition routes revealed
                      non-classical nucleation and growth paths involving
                      amorphous precursor phases and aggregative growth steps.
                      With the knowledge of this kinetic mechanism we
                      systematically examined a range of different iron oxide
                      heat-up synthesis routes to understand and conclude which
                      methods allow good and reproducible size control over a
                      range of relevant nanoparticle diameters. Using transmission
                      electron microscopy (TEM) and small-angle X-ray scattering
                      (SAXS) for the characterization of the nanoparticle size
                      distribution we find that a set of solvents (1-octadecene,
                      trioctylamine, docosane) provides access to a temperature
                      range between 300 – 370°C allowing to synthesize
                      monodisperse nanoparticles in a size range of 5 – 24 nm on
                      large scale. We confirm that a thermal pretreatment of the
                      iron oxide precursor is essential to achieve reproducible
                      size control. We find that each solvent provides access to a
                      certain temperature range, within which the variation of
                      temperature, heating rate or precursor concentration allows
                      to reproducibly control the nanoparticle size.},
