abstract = {Nanoparticle (NP) self-assembly is a promising tool for the
straightforward preparation of complex materials without
lithography. Self-assembly on liquid subphases is
established for the preparation of thin NP films with
quasicrystalline order on large scales. Small-angle X-ray
scattering (SAXS) at synchrotron radiation sources is in
particular advantageous to study self-assembly in situ,
providing detailed structural information with high temporal
resolution. Here we present a new experimental setup that
allows measuring SAXS in a vertical geometry. This way it is
possible to study the self-assembly of nanoparticles on
liquid subphases in situ as demonstrated with gold
nanoparticles. In contrast to measurements with grazing
incidence (GISAXS), spatial resolution in the µm range and
sampling of the volume material is possible. Integration of
optical microscopy allows observing the measurement position
and formation of supercrystal flakes. The setup can be used
to study self-assembly of various nanoparticles on liquid
subphases but is not limited to such studies. It was
realized at the beamline P10 at PETRA III (Deutsches
Elektronen-Synchrotron DESY, Hamburg, Germany).},
