A method is presented and applied, capable of retrieving form-free particle size distributions complete with uncertainties from small-angle scattering patterns. Special attention is paid to particle observability in the scattering patterns, accurate estimation of data uncertainty and the effect of uncertainty on the resulting size distribution statistics.
laboratory notes
Window materials for small-angle X-ray scattering measurements have been evaluated using a vacuum camera. It is shown that window materials vary in how they scatter the background signal depending on the q range.

An algorithm for determining the element-selective charge density is developed using multi-wavelength anomalous synchrotron X-ray powder diffraction data. The method is employed in order to resolve the disordered structure of yttrium in (Y@C82)(C6H5CH3).

A high-precision spin-coater system has been designed, implemented and used to investigate the formation process and film thickness of a triblock copolymer using grazing-incidence small-angle X-ray scattering (GISAXS) with high temporal resolution.
