The flow of wormlike polymeric micelles can be studied using SAXS by scanning the microfluidic channel with a microfocused X-ray beam. (a) The measured SAXS patterns reveal micelles in parallel, tilted, transitional and perpendicular orientations depending on their location, as indicated by the straight lines. (b) The information from these SAXS patterns is used to generate color maps in real time using DPDAK. Each of these pixels is color coded on the basis of the averaged ROI of the parallel or the perpendicular micelle orientation. (c) The SAXS results are also in good agreement with the corresponding polarization microscopic images that are based on the samples birefringence. Here, the blue color represents a parallel micelle orientation with respect to the flow, while the orange color indicates a perpendicular orientation.
