Poling of liquid crystals in thin films
The European Physical Journal E, 2003We examine the effect of a strong DC electric field on the molecular orientational order and the nonlinear optical response of liquid crystals in thin films. We compare the results of second-harmonic generation measurements with the predictions of two models, one assuming that the dipoles carried by the molecules have no interactions (the isotropic ...

Amphiphilic nanostructures in thin liquid films
Advances in Colloid and Interface Science, 2005A survey on recent experimental investigations of microscopic foam films containing self-assembled amphiphilic nanostructures is presented. The film characteristics are investigated via microinterferometric method, which operates with the measuring cell of Scheludko-Exerowa.

The first studies of thin liquid films were inspired by the vivid colors of films surrounding soap bubbles. These liquid films are stabilized by two monolayers of soap molecules adsorbed at both their inner and outer surfaces. The films thin due to gravity, and when their thickness reaches values of the order of 1 μm, beautiful colors are observed ...

Flagellated microswimmers: Hydrodynamics in thin liquid films
The European Physical Journal E, 2018The hydrodynamics of a flagellated microswimmer moving in thin films is discussed. The fully resolved hydrodynamics is exploited by solving the Stokes equations for the actual geometry of the swimmer. Two different interfaces are used to confine the swimmer: a bottom solid wall and a top air-liquid interface, as appropriate for a thin film. The swimmer

Marginal Regeneration in Thin Vertical Liquid Films
Journal of Colloid and Interface Science, 1998Marginal regeneration is the rate-determining drainage mechanism in mobile vertical liquid films stabilized with surfactants. Mysels, Frankel, and Shinoda explained this process from (thermal) thickness fluctuations, like capillary waves. The Laplace underpressure in the Plateau border would exert a larger force on a thick, rather than on a thinner ...

Hydrodynamics of thin liquid films. Rate of thinning of emulsion films from pure liquids
International Journal of Multiphase Flow, 1976Abstract A hydrodynamic theory of the process of thinning of one-sided and symmetrical emulsion films is presented. The theory is essentially based on three assumptions: 1. the film is considered as being thin in the hydrodynamic sense; 2. the film surfaces are assumed to be plane-parallel, and 3.

Dynamics of Liquid Films and Thin Jets
SIAM Journal on Applied Mathematics, 1979The theory of liquid films and thin jets as one- and two-dimensional continuums is examined. The equations of motion have led to solutions for the characteristic speeds of wave propagation for the parameters characterizing the shape. The formal analogy with a compressible fluid indicates the possibility of shock wave generation in films and jets and ...

Abstract Liquid boiling has been studied experimentally in a thin film formed over a limited surface area by supplying liquid through a spray nozzle. Water, ethanol, carbon tetrachloride and benzene were used in these experiments. Pressure ranged within 0·08-1 bar. In this study some new correlations have been obtained such as higher critical fluxes

The study of soap films, which are symmetrical, has a distinguished history. More recently, other asymmetric liquid films (e.g. pseudo-emulsion films and wetting films on solids) have been widely investigated. The (meta)stability of thin liquid films can be understood in terms of disjoining pressure isotherms, the shapes of which reflect the nature of ...
