Dark-Field X-ray Microscopy for 2D and 3D imaging of Microstructural Dynamics at the European X-ray Free Electron Laser
Sara J. Irvine, Kento Katagiri, Trygve M. Ræder +26
Dark field X-ray microscopy (DXFM) can visualize microstructural distortions in bulk crystals. Using the femtosecond X-ray pulses generated by X-ray free-electron lasers (XFEL), DF…
Nanoscale inhomogeneity of charge density waves dynamics in LaSrNiO
Gaetano Campi, Antonio Bianconi, Boby Joseph +7
While stripe phases with broken rotational symmetry of charge density appear in many complex correlated systems, the heterogeneity of spatial ordering and dynamics remains elusive.…
On the use of multilayer Laue lenses with X-ray Free Electron Lasers
Mauro Prasciolu, Kevin T. Murray, Nikolay Ivanov +34
Multilayer Laue lenses were used for the first time to focus x-rays from an X-ray Free Electron Laser (XFEL). In an experiment, which was performed at the European XFEL, we demonst…
Resolving molecular diffusion and aggregation of antibody proteins with megahertz X-ray free-electron laser pulses
Mario Reiser, Anita Girelli, Anastasia Ragulskaya +26
X-ray free-electron lasers (XFELs) with megahertz repetition rate can provide novel insights into structural dynamics of biological macromolecule solutions. However, very high dose…
Using low dose X-ray Speckle Visibility Spectroscopy to study dynamics of soft matter samples
Johannes Möller, Mario Reiser, Jörg Hallmann +10
We demonstrate the successful application of X-ray Speckle Visibility Spectroscopy (XSVS) experiments to study the dynamics of radiation sensitive, biological samples with unpreced…
Measurement of spin dynamics in a layered nickelate using x-ray photon correlation spectroscopy: Evidence for intrinsic destabilization of incommensurate stripes at low temperatures
Alessandro Ricci, Nicola Poccia, Gaetano Campi +15
We study the temporal stability of stripe-type spin order in a layered nickelate with X-ray photon correlation spectroscopy and observe fluctuations on time scales of tens of minut…
Direct Visualization of Spatial inhomogeneity of Spin Stripes Order in La1.72Sr0.28NiO4
Gaetano Campi, Nicola Poccia, Boby Joseph +14
In several strongly correlated electron systems, defects, charge and local lattice distortions are found to show complex inhomogeneous spatial distributions. There is growing evide…
Unravelling structural rearrangement of polymer colloidal crystals under dry sintering conditions
Alexey V. Zozulya, Ivan A. Zaluzhnyy, Nastasia Mukharamova +7
Structural rearrangement of polystyrene colloidal crystals under dry sintering conditions has been revealed by in situ grazing incidence X-ray scattering. Measured diffraction patt…
Low dose X-ray speckle visibility spectroscopy reveals nanoscale dynamics in radiation sensitive ionic liquids
Jan Verwohlt, Mario Reiser, Lisa Randolph +6
X-ray radiation damage provides a serious bottle neck for investigating μs to s dynamics on nanometer length scales employing X-ray photon correlation spectroscopy. This limitation…
Nucleation of dislocations and their dynamics in layered oxides cathode materials during battery charging
A. Singer, S. Hy, M. Zhang +15
Defects and their interactions in crystalline solids often underpin material properties and functionality as they are decisive for stability, result in enhanced diffusion, and act…
