Studies in interface science ; v. 5
Inhalt:
The main physicochemical aspects of foam and foam films such as preparation, structure, properties, are considered, giving a special emphasis on foam stability. It is shown that the foam and foam films are an efficient object in the study of various surface phenomena and in establishing regularities common for different interfaces, in particular, water/oil interface. The techniques and results on foam films have an independent meaning and involve the latest achievement in this field, with a focus on authors' results. The book has an expressed monographic character. It reveals joint ideas, i.
