In-situ study of the growth process of magnetite mesocrystals by self-assembly of nanoparticles using simultaneous small- and wide-angle di

DOI

We propose detailed in situ studies of the nanoparticle-mediated growth process of magnetite single domain mesocrystals by X-ray diffraction. Such mesocrystalline systems are characterized by both long-range packing arrangement and orientational order of nanoparticles. Therefore, the in-situ study of the self-assembly process should reveal the aggregation dynamic of nanoparticles and their crystallographic alignment during mesocrystal growth. Recently, we have demonstrated that simultaneous collection of small- and wide-angle X-ray scattering with the same detector greatly improves the precision of scattering geometry optimization and increases the recoverable information content. Thus, simultaneously the average structure of nanoparticle units and their assembly can be studied. The approach allows us to answer scientific requests such as the general understanding of the microscopic assembly mechanism of natural and human-made mesocrystalline materials.
