B12 - Imaging of surfactant stabilized nanostructures using microfluids

Our aim is to study how the microscopic and nanoscopic details of interfaces drive the macroscopic behavior of two-phase fluids. Using x-ray imaging techniques and fluorescence microscopy we want to resolve the dynamics of transient mechanisms such as bilayer formation and rupture, network formation of bilayers, and micellar or surfactant transport. We will use microfluidic systems to control these structures to provide new quantitative insights in the understanding of dynamical processes in multiphase fluids.
