Small-Angle X-ray Scattering: Characterization of cubic Au nanoparticles using Debye's scattering formula
Jérôme Deumer, Brian R. Pauw, Sylvie Marguet +4
We propose a versatile software package in the form of a Python extension, named CDEF (Computing Debye's scattering formula for Extraordinary Formfactors), to approximately calcula…
Retarding the growth of the {Rosensweig} instability unveils a new scaling regime
Adrian Lange, Christian Gollwitzer, Robin Maretzki +2
Using a highly viscous magnetic fluid, the dynamics in the aftermath of the Rosensweig instability can be slowed down by more than 2000 times. In this way we expand the regime wher…
Homoclinic snaking near the surface instability of a polarizable fluid
David J. B. Lloyd, Christian Gollwitzer, Ingo Rehberg +1
We report on localized patches of cellular hexagons observed on the surface of a magnetic fluid in a vertical magnetic field. These patches are spontaneously generated by jumping i…
Nanoparticle characterization by continuous contrast variation in SAXS with a solvent density gradient
Raul Garcia-Diez, Christian Gollwitzer, Michael Krumrey
Many low-density nanoparticles show a radial inner structure. This work proposes a novel approach to contrast variation with SAXS based on the constitution of a solvent density gra…
Characterization of an in-vacuum PILATUS 1M detector
Jan Wernecke, Christian Gollwitzer, Peter Müller +1
A dedicated in-vacuum X-ray detector based on the hybrid pixel PILATUS 1M detector has been installed at the four-crystal monochromator beamline of PTB at the electron storage ring…
A diffraction effect in X-ray area detectors
Christian Gollwitzer, Michael Krumrey
When an X-ray area detector based on a single crystalline material, for instance, a state of the art hybrid pixel detector, is illuminated from a point source by monochromatic radi…
