Trends in Colloid and Interface Science IX

This volume contains the proceedings of the VIIIth annual meeting of the European Colloid and Interface Society (ECIS) which took place in Montpellier, France, in September 1994.
The contributions cover a broad range of fields in modern colloid science, as well as their technical, experimental and theoretical aspects. Specific emphasis is given to:
- Mixed systems: amphiphilic phases incorporating foreign particles
- Concentrated suspensions and emulsions: structure and mechanical properties
- Interactions and long-range order
- Supramolecular structures under flow
- Bio-colloids
