(SAXS)The microscopic inhomogeneity in a supercritical mixture of (CO2)1−x(H2O)x (x=0.003) has been studied by small-angle X-ray scattering (SAXS) at 308.2 K and six different pressures/densities. The results show that the correlation length and density fluctuation is maximized near ...
1. Study of molded styrene-4-vinylpyridinium ABA blocks by SAXS and SANS The bulk morphology of 4-vinylpyridinium-b-styrene-b-4-vinylpyridinium ABA block ionomers with short ionic blocks has been studied by small-angle X-ray scattering (SAXS) as a function of the length of both A and ...
We calculate the signal to noise ratio (SNR) of XPCS experiments from a concentrated lysozyme solution at the length scale of the hydrodynamic radius of the protein molecule. We take limitations given by the critical X-ray dose into account and find expressions for the SNR as a function of ...
10 with visual damage. We begin with CT and connect this to a comprehensive SAXS/WAXS mapping of the impact site. We parameterize these data by identifying suitable descriptors at each structural level, and identify different spatial domains. These include domains of severe damage (visual), intact...
Experimental configuration. The experiment was performed at EH3 of BL3 beamline of the Spring-8 Angstrom Compact Free Electron Laser (SACLA)38 in a small-angle X-ray scattering (SAXS) geometry. The photon energy was set to 8 keV with a bandwidth of Δ E/E ~ 5 × ...

In particular, the exceptional large transverse coherence of the X-ray pulses and the high time-averaged flux promises to reach time and length scales that have not been accessible up to now with storage ring based sources. However, due to the fluctuations originating from the stochastic nature ...
