“…The experiments on penetration of a soluble surfactant into an insoluble surfactant monolayer by Schulman et al (see Section 6.10) have shown not only that the structure of the monolayer film is changed by the penetrating species but also that the kinetics of adsorption is affected. Numerous examples of the effects produced by these nonionic additives (foam builders) are described by Miles (1945), Miles et al (1950), Epstein et al (1954a,b), , Davies (1957), Kaertkemeyer (1957), Schick and Fowkes (1957), etc.…”

“…The experiments were conducted in round glass stoppered bottles with fixed internal frames similar to the ones described by Miles et aZ. 16 in a water bath the temperature of which was controlled to 0.01 "C so that evaporation was negligible. A small fluorescent lamp was used for illuminating the films.…”

The conditions under which the two black films-the first of greater and variable thickness and the second of about 44A-are formed by solutions of sodium dodecyl sulphate in the presence of NaCl are established and the effect of several additives upon the relative stability of these two films is investigated. Specific effects of counterions upon this behaviour are marked and are interpreted in terms of an ionic size effect upon the structure of the second black film and of preferential surface adsorption. Some conclusions about the composition and heat of formation of the second black lilm are drawn using Le Chatelier's principle. At higher ionic strengths counterions have atso specific effects upon the thickness of the first black film in line with their hydrated size and adsorption.

“…The role of surface "rigidity" on the mode of foam film thinning was first described by Miles et al [1] and then elaborated in great detail in the classical book "Soap Films" by Mysels et al [2]. In a series of experimental observations with solutions of different surfactants, these authors revealed several modes of foam film thinning and the terms "rigid" and "mobile" films were introduced for the two extreme types of behaviour.…”

Surface phase transitions in surfactant adsorption layers are known to affect the dynamic properties of foams and to induce surface nucleation in freezing emulsion drops. Recently, these transitions were found to play a role in several other phenomena, opening new opportunities for controlling foam and emulsion properties. This review presents a brief outlook of the emerging opportunities in this area. Three topics are emphasized: (1) The use of surfactant mixtures for inducing phase transitions on bubble surfaces in foams; (2) The peculiar properties of natural surfactants saponins which form extremely viscoelastic surface layers; and (3) The main phenomena in emulsions, for which the surface phase transitions areimportant. The overall conclusion from the reviewed literature is that surface phase transitions could be used as a powerful tool to control many foam and emulsion properties, but we need deeper understanding of the underlying phenomena to explore fully these opportunities.
