Ultrafast X-ray Scattering from Molecules [PDF]
Journal of Chemical Theory and Computation, 2016 We present a theoretical framework for the analysis of ultrafast X-ray scattering experiments using nonadiabatic quantum molecular dynamics simulations of photochemical dynamics. A detailed simulation of a pump-probe experiment in ethylene is used to examine the sensitivity of the scattering signal to simulation parameters.

Resonant soft X‐ray scattering in polymer science
Journal of Polymer Science, 2021 Resonant soft X-ray scattering (RSoXS) is an emerging, powerful technique to probe the nano-to-mesoscale structure of polymers and other molecules. It joins together small-angle X-ray scattering (a statistical nanoprobe) with X-ray spectroscopy that ...

End-condition for solution small angle X-ray scattering measurements by kernel density estimation
Science and Technology of Advanced Materials: Methods, 2022 We develop a method for calculating the minimum X-ray exposure time for X-ray solution scattering experiments using statistical and mathematical approaches to enhance the measurement efficiency while maintaining data quality.

Stimulated resonant inelastic X-ray scattering in a solid
Communications Physics, 2022 X-ray free electron lasers provide brilliant light with sufficient intensity to strongly drive and probe nonlinear X-ray-matter interactions. Here, spectroscopy of Co/Pd multilayers reveals a nearly one-million-fold enhancement of stimulated resonant ...

X-ray Raman scattering study of aligned polyfluorene [PDF]
, 2006 We present a non-resonant inelastic x-ray scattering study at the carbon K-edge on aligned poly[9,9-bis(2-ethylhexyl)-fluorene-2,7-diyl] and show that the x-ray Raman scattering technique can be used as a practical alternative to x-ray absorption ...

Ray-tracing Simulations and Spectral Models of X-Ray Radiation in Dusty Media
The Astrophysical Journal, 2023 Dust can play an important role in shaping the X-ray spectra and images of astrophysical sources. In this work we report on the implementation of dust in the ray-tracing platform RefleX .
