Foam films as instrumentation in the study of amphiphile self-assembly
Elena Mileva,Dotchi Exerowa +1 more
TL;DR: In this paper, a survey of recent experimental investigations of microscopic foam films containing self-assembled amphiphilic structures is presented, where unstable black patterns (dots and spots) are observed; they have very short lifetimes and the films which contain them rupture quickly.
Journal ArticleDOI
Experimental Evidences of Self-Assembly in Foam Films from Amphiphilic Solutions
TL;DR: In this paper, the authors show that the onset of the unstable black formations results in a sharp increase in the foam film lifetimes, which is interpreted as related to the disintegration of the amphiphilic structures in the process of film drainage.
Journal ArticleDOI
Amphiphilic nanostructures in thin liquid films.
TL;DR: The results show that the microscopic foam film technique has a serious potential as a prospective instrumentation for the study of amphiphilic self-assemblies in surfactant solutions.

Dynamics of surface waves in wetting films
TL;DR: In this article, the dispersion relation of linear waves in wetting films is derived based on the Reynolds lubrication theory, assuming interfacial mobility on the two film surfaces, and the final result accounts for both the Marangoni effect on the liquid/gas surface and the slippage on the solid/liquid interface.
Journal ArticleDOI
Drainage time peculiarities of foam films from amphiphilic solutions
TL;DR: In this article, it is established that the drainage time of thinning foam films goes up in a stepwise manner at the increase of the amphiphile quantity, and that the climb occurs at the same surfactant concentrations where the onset of the kink regions in the surface-tension curves is observed.

The slow motion of a sphere through a viscous fluid towards a plane surface
TL;DR: In this paper, bipolar co-ordinates are employed to obtain exact solutions of the equations of slow viscous flow for the steady motion of a solid sphere towards or away from a plane surface of infinite extent.

Close approach and deformation of two viscous drops due to gravity and van der waals forces
S.G. Yiantsios,Robert H. Davis +1 more
TL;DR: In this article, the rate of approach and deformation of two small drops of different sizes in buoyancy-driven axi-symmetric motion is analyzed within the asymptotic limit of small capillary number, in which deformation becomes important only when the minimum separation between the drops is much smaller than either radius.

Film flow and coalescence-I Basic relations, film shape and criteria for interface mobility
J.C. Lee,T.D. Hodgson +1 more
TL;DR: In this paper, an equation relating the profile of a thin film formed between a drop and an interface, or between two drops, to the pressure drop due to flow is derived, and the influence of interfacial tension gradients on tangential movement of the interface itself is examined in detail.
