Flow-induced lamella-to-MLV transformation: flow-through vs. rheo-SAS
Soft matter under flow is ubiquitous in both industry and biology, but not frequently investigated scientifically. In contrast to rheo-SAS with very well-defined shear and deformation, a flow-through setup is flexible and conceptually easy, but the mechanical stress on the sample is less controlled and homogeneous. In order to complement previous measurements on the lamella to MLV-transition in the system TDMAO/cosurfactant/water done in our group (V4, HZB Berlin), we would like to measure two samples. We will then be able to systematically contrast our results from rheo-SAXS (ID02, ESRF) with the effects observed due to flow-induced shear, which we believe to promise insight not only on the system, but also further development in the analysis of flow-through data.
