Popis:	Nonideal mixed yet structured chemical reaction systems tend to exhibit spatial inhomogeneities in their conversion kinetics. Reactive two-phase systems invariably involve coupling phenomena between transport processes and the chemical reaction, at least in the phase boundary region. The spatiotemporal structure of the dispersion determines the contact area as well as contact times, local penetration depths, thus setting the boundary conditions for chemical conversion kinetics and mass transport processes. A monodispersive foam is a system of reduced complexity for investigating spatial and temporal reaction kinetics in conjunction with transport processes. Producing a well-defined foam with equally sized bubbles is a difficult task. After solving this problem, we introduce chemical reactive species into the foams and observe their physicochemical behavior.
