Smectic liquid crystals can be viewed as model systems for lamellar structures for which there has been extensive theoretical development. We demonstrate that a nonlinear energy description is required with respect to the usual Landau-de Gennes elast

Behavior of colloidal particles in thin liquid crystal films

Autor: Jeridi, Haïfa

Publikováno v: Matière Molle [cond-mat.soft]. Université de Tunis El Manar, 2017. Français

The confinement of colloidal particles in thin liquid films is typically accompanied with interfacial deformations which give rise to long-range capillary forces, attractive in most of the cases. In simple fluids, these capillary forces compete mostl
