Products based on foams and emulsions are omnipresent in our modern world and we see them from morning till night. We enjoy foams and emulsions during our meals not only in the form of ice cream or mousse au chocolate. Moreover, we are impressed with foamed metals, which have an enormously lower weight than solid materials and often have even much better mechanical properties.
