Facility for Absorption and Surface Tension (FASTER) - 12.03.13
Science Objectives for Everyone
Facility for Absorption and Surface Tension (FASTER) investigates how surfactants (surface acting agents that reduce the surface tension of water) will affect the physical chemistry properties and emulsion stability of droplet interfaces.

FASTER is scheduled for its first operations on ISS Increment 23/24.
- FASTER aims to determine the characteristics of liquid/liquid interface surfactant adsorption dynamics (how the surfactant interaction with liquids affects the flow).
- FASTER will investigate adsorption dynamics (how binding of molecules to a surface affects flow), surfactant transfer (when the surfactant crosses the liquid/liquid boundary), interfacial rheology (flow properties of interfaces), and the role of surfactants in stabilization (maintaining droplet interfaces).
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 characteristic scales of time and length will help engineers predict the behaviour of emulsions and factor it into the design of space systems.Earth Applications
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. FASTER can provide knowledge enabling optimisation of the design of surfactants, or of their utilisation, towards greener products.
