We discuss the peculiarity of thin nematic films on solid substrates with a free surface, underlining the differences with what is usually seen in dewetting. We review the thermodynamic basis of the coupled phase/thickness separation that has previou

Adhesion of colloids on a cell surface in competition for mobile receptors

Autor: Didier Roux, D. van Effenterre

Publikováno v: Europhysics Letters (EPL). 64:543-549

In this letter, we study theoretically the adhesion of colloidal particles (such as virus, liposomes, nanovectors...) on the surface of a cell. The Brownian colloidal particles bear specific ligands at their surface and might bind to one or several f

Coupling between the nematic/isotropic transition and a thickness transition: A theoretical approach

Autor: M. P. Valignat, D. van Effenterre, Didier Roux

Publikováno v: Europhysics Letters (EPL). 62:526-532

In this letter, we develop a theoretical model of the effect of a free surface on the nematic-to-isotropic phase transition in a confined geometry. Simply by coupling a bulk first-order phase transition with a thickness-dependent elastic distortion f

Thin films in wetting and spreading

Autor: Christophe Poulard, F. Vandenbrouck, D. van Effenterre, M. Cachile, M. P. Valignat, O Bénichou, Anne-Marie Cazabat

Publikováno v: Advances in Colloid and Interface Science. :381-398

Thin films differ from bulk phases both from a thermodynamic point of view, i.e. the chemical potential of a molecule in a film depends on the film thickness, and in their dynamical response, because relaxation times may become large in these confine

Confined diffusion of hydrophilic probes inserted in lyotropic lamellar phases

European Physical Journal A, EDP Sciences, 2008, 26, pp. 225-234. ⟨10.1140/epje/i2007-10318-9⟩

The dynamic behaviour of three hydrophilic probes (two dyes and one fluorescently-labelled protein) inserted in the water layers of lyotropic lamellar phases has been studied by confocal fluorescence recovery experiments. Two different, ionic (AOT/Na

Binary separation in very thin nematic films: thickness and phase coexistence

Autor: A. M. Cazabat, R. Ober, D. van Effenterre, M. P. Valignat

Publikováno v: Physical review letters. 87(12)

The behavior as a function of temperature of very thin films (10 to 200 nm) of pentylcyanobiphenyl (5CB) on silicon substrates is reported. In the vicinity of the nematic/isotropic transition we observe a coexistence of two regions of different thick
