Double emulsion thermomorphous droplets flowing in a capillary outside (top) and inside (bottom) of the heating bath. Cooling and heating takes some time but the phase transition can be seen clearly. (Video not available)
Collecting and phase separation of the reaction mixture (colorized example). Orange: organic phase; colorless: catalyst containing FC40 ; blue: water phase
