Full Description
The 37th General Meeting of the German Colloid Society, held in Dresden, September 1995, is the basis of this volume. It points to the important role that interface phenomena play in technological processes. This volume deals with theory and application aspects in the fields of
- preparation and stability of dispersions and emulsions;
- adsorption of surfactants;
- polyelectrolytes and neutral polymers on solid surfaces
- wetting processes and
- electrokinetic phenomena.
Investigations on new methods to characterize interfaces, surfactants and colloids are also presented.
