This volume contains the proceedings of the IXth annual meeting of the European Colloid and Interface Society (ECIS) which took place in Barcelona, Spain, in September 1995. 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:
- Surfactant aggregates, micelles, vesicles and liquid crystals;
- Colloidal particles: interaction, structure and aggregation;
- Emulsions and concentrated systems;
- Microemulsions;
- Mixed colloidal systems; - Rheology;
- Biocolloids; - Membranes, films and interfaces.
