Surface-assisted monodomain formation of an ordered phase of soft matter via the first-order phase transition

We produced a monodomain ordered structure with the help of a surface-mediated first-order transition, using a sponge-to-lamella transition in a membrane suspension as a model system. The long characteristic length and time scales of the system allow us to observe the process of the phase ordering in a confined geometry with optical microscopy in real time. We demonstrate that a homogeneously ordered domain can be attained if we prevent nucleation in bulk by using its kinetic coupling to nucleation on the surface.
