Fundamental and Applied Studies of Emulsion Stability (FASES) - 07.14.16
Emulsions are very common on Earth, in nature such as milk, and also in man-made products. The Fundamental and Applied Studies of Emulsion Stability (FASES) is investigates the physical principles which determine the stability of different emulsions and which compounds can influence this. This knowledge is very helpful to industry in using/designing the best compounds to stabilise or destabilise different emulsions depending on their use and optimising their utilisation towards greener products.

FASES (Fundamental and Applied Studies in Emulsion Stability) will investigate the emulsion stability in relation to the physical-chemistry of droplet interfaces in order to obtain a model of emulsion dynamics that can be transferred to industrial applications.
The main objective of the FASES is the study and observation of emulsion coarsening kinetics in a 0-g environment.
- Microgravity provides a unique possibility for an effective study of all the basic mechanisms (Ostwald ripening, coalescence and aggregation) underlying the emulsion stability. This environment also provides for the avoidance of the perturbing effects of convective flows and of droplet segregation. It is an effective condition for the study of adsorption dynamics and droplet coalescence and aggregation.
These studies will address single and multiple interfaces, as affected by various surfactants. An important part of the program aims at establishing links between emulsion stability and physico-chemical characteristics of droplet interfaces. Further experiments are planned to investigate droplet dispersion in emulsions and phase inversion. On the basis of these studies, the team plans to generate a model of emulsion dynamics to be transferred to industrial applications.
Some fluid handling processes in space are prone to involve emulsions and there the absence of the effect of gravity may influence their life time. A good knowledge of the mechanisms involved and their characteristics will help engineers predict the behaviour of emulsions and factor it into the design of space systems.
Emulsions are present everywhere in our daily lives starting with milk and most dairy products, and including also common water-oil mixtures in other food or industrial products. Depending on the process or product it deals with, industry is in demand of knowledge about how to stabilise or destabilise an emulsion. FASES can provide knowledge enabling optimisation of the design of surfactants or of their utilisation towards greener products. Data from the experiment will help with the generation of emulsion dynamics models to be transferred to industrial applications.
Operational Requirements and Protocols
2) The ground filling procedure of the 28 ITEM sample cells and 16 EMPI sample cells shall be performed in such a way that some of the ITEM and EMPI samples are processed in orbit as quickly as feasible after filling.
3) The EC shall be unstowed and transferred from cargo upload vehicle within berthing +12hrs so that the first set of samples (4 in total) can be processed within optimally within 50days from filling.
FASES will operate in the Fluid Science Laboratory (FSL) between 85 and 200 days while on board ISS.
