Coupling x-ray photon correlation spectroscopy and dynamic coherent x-ray diffraction imaging: Particle motion analysis from nano-to-micrometer scale

Physical Review Research, 2023
Two well-known measurement methods use coherent x rays: x-ray photon correlation spectroscopy (XPCS) and coherent x-ray diffraction imaging (CXDI). We propose and demonstrate an approach to analyze particle motion in heterogeneous solutions over a wide ...

Software tools for X-ray photon correlation and X-ray speckle visibility spectroscopy [PDF]

2016 New York Scientific Data Summit (NYSDS), 2016
A set of new data analysis software tools have been developed for the study of structural dynamics of materials using coherent scattering and photon correlation techniques. The new software tools can readily process high-throughput, multidimensional data, enabling studies of slow and fast dynamics of materials using X-ray Speckle Visibility ...

Effects of partial coherence on correlation functions measured by x-ray photon correlation spectroscopy [PDF]

Physical Review B, 2008
We present a rigorous description of the effects of partial coherence and detector resolution on intensity autocorrelation functions as they can be measured by x-ray photon correlation spectroscopy (XPCS). Based on the Huygens-Fresnel propagation law and on the first Born approximation, we derive a general expression for the normalized intensity ...

Kinetic viscoelasticity during early polymer-polymer spinodal dewetting

Physical Review Research, 2021
The dewetting kinetics of a supported polymer bilayer were measured in situ using coherent grazing-incidence x-ray scattering. X-ray photon correlation spectroscopy provides both the two-time correlation functions and the cross-correlation function which

X-ray photon correlation spectroscopy revealing the change of relaxation dynamics of a severely deformed Pd-based bulk metallic glass [PDF]

, 2020
The influence of severe plastic deformation on the relaxation dynamics of a Pd40Ni40P20 (at.%) bulk metallic glass was investigated on the atomic length scale by X-ray photon correlation spectroscopy and fluctuation electron microscopy.
