    Experiment Description

    Research Overview

    • 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.

    Description

    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.

    Applications

    Space Applications

    Understanding the microgravity characteristics of emulsions and related physic-chemical solutions and compounds may allow researchers to better produce and handle items used by future space explorers and enhance our ability to live in space for longer durations.

    Earth Applications

    Emulsions are usually a mixture of two liquids that don’t mix well (immiscible) and are often inherently thermodynamically unstable due to their differing solubilities. Emulsions are associated with a vast number of everyday materials and products including industrial processing solutions, food products, personal care items, and are even used to deliver multiple active pharmaceutical ingredients. In addition, by understanding materials that can greatly reduce the surface tension of a solutions constituents may also enhance our ability to produce more stable and long lived emulsions, thus greatly enhancing shelf life of many products used today.

    Operations

    Operational Requirements

    1) The EC shall never be exposed to freezing temperatures.
    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.

    Operational Protocols

    FASES will operate in the Fluid Science Laboratory (FSL) between 85 and 200 days while on board ISS.
