Projects

Fundamental and Applied Studies in Emulsion Stability (FASES)

Funding European Space Agency (ESA)

Start 01-09-2010

End 31-07-2013

Project Team

The project team consists of the representatives from six European Universities, two Research Institutes and three SMEs

Scope

The project FASES is a direct result of the activity of the ESA Topical Team "Equilibrium and Dynamic Properties of Adsorbed Layers". The study of the stability of emulsions, as related to the chemico-physical properties of the corresponding liquid-liquid interfaces, was identified as an important application field that can benefit both from the expertise of the Team and from microgravity studies.

According to the present status of art, the links between the physical chemistry of the droplets interface to the liquid films and finally to the collective properties of an emulsion are only qualitative, so that the criteria used in industry are mainly empirical.

The FASES project aims at filling this gap, which is an important limitation of the emulsion science and for the development of applications. In fact, the study of adsorption dynamics, as applied to the stability of emulsion and supported by the development of new theoretical and experimental tools can lead to a significant improvement of the insight on these systems which will efficiently support the technologic needs.

UNITWE Work Package: Wettability of nanoparticles

(i)Experimental characterization of nanoparticles wettability acting as stabilizers for Pickering and suspoemulsions using indirect characterisation methods such as Washburn, modified Wilhelmy plates as well as by water vapour adsorption isotherms

(ii)Understanding and description of different wetting regimes using a concept developed earlier which is based on Eyring rate processes approach and experimentally obtained parameters

(iii)Analysis of surface roughness parameters, calculation of the Hurst exponent of the surfaces using fractal concept

UNITWE Work Package: Rheology of Pickering and suspo-emulsions

(i)Studies of rheological behaviour (linear and non-linear) of different water-in-oil and oil-in-water emulsion systems stabilized by modified disperable colloidal Boehmite alumina nanoparticles with or without emulsifier at different storage time

(ii)The DSC results, optical microscopic images, TEM images of these emulsion systems will be analysed and discussed in order to get better understanding of the potential relationship among the rheology, microstructure and stability of emulsions     


Since May 2011 University of Twente (responsible: Victoria Dutschk) is the Dutch contact point for experiments on foams and emulsions on Earth as a reference for similar experiments on the space shuttle Mars
