Foams from non-aqueous systems

The multi-phase approach to clarify the fundamentals of the stability of foams from non-aqueous liquids has been further developed. The two-phase liquid/liquid crystal line of attack for the liquid oil variety has been extended to foams stabilized by solid particles, in turn leading to progress in the fundamental science of solid metal foams and plastic foams.
