The definition of methodologies for the stabilisation or destabilisation of liquid disperse systems, such as foams and emulsions, is an important scientific and technological goal, with spin-offs for a vast number of technologies, processes and products. Progresses in this area require intensive investigation and modelling of the processes occurring on different timescales and dimensions: the physical chemistry of liquid interfaces and films, droplet interaction and internal dynamics of the emulsion. Through the damping of convection and the suppression of buoyancy, microgravity conditions provide unique opportunities for studies: a purely diffusive environment for the investigation of transport and adsorption of surface active molecules and the possibility of studying droplet coalescence and aggregation processes decoupled from sedimentation or creaming. The fundamental and Applied Studies in Emulsion Stability (FASES) MAP project was set up to study the links between the properties of droplet interfaces and films, and the basic mechanisms (aggregation and coalescence) involved in the destabilisation of emulsions. Key microgravity experiments will provide data and/or tests of the developed models, in conjunction with extensive ground investigations. To this end, two International Space Station facilities are under development: Facility for Adsorption and Surface Tension study (FASTER) to investigate the physical chemistry of the single interfaces and liquid-liquid films, and the FASES Experiment Container for the Fluid Science Laboratory to investigate emulsion dynamics and the drops interaction.
