Equilibrium shape of lyotropic cubic monocrystals
The faceting of air bubbles included in large monocrystals of a lyotropic cubic phase is described The shape of the bubbles, which form « negative crystals », is analyzed the facets are found to corrrespond to (211) reticular planes of the crystal, which are indeed the reticular planes having the largest inter-reticular spacing It is suggested that the observed shape is close to an equilibrium ...
متن کاملLyotropic Liquid Crystal Phases from Anisotropic Nanomaterials
Liquid crystals are an integral part of a mature display technology, also establishing themselves in other applications, such as spatial light modulators, telecommunication technology, photonics, or sensors, just to name a few of the non-display applications. In recent years, there has been an increasing trend to add various nanomaterials to liquid crystals, which is motivated by several aspect...
متن کاملSurface relaxation of lyotropic lamellar phases
– We study the relaxation modes of an interface between a lyotropic lamellar phase and a gas or a simple liquid. The relaxation is found to be qualitatively different from those of both simple liquids and single-component smectic-A liquid crystals. It is governed by a non-inertial, diffusive mode whose decay rate increases quadratically with wavenumber, |ω| = Aq. The coefficient A depends on th...
متن کاملAlkyl-bis(imidazolium) salts: a new amphiphile platform that forms thermotropic and non-aqueous lyotropic bicontinuous cubic phases.
New ionic amphiphiles with a hexyl-bridged bis(imidazolium) headgroup; Br(-), BF4(-), or Tf2N(-) anions; and a long n-alkyl tail can form thermotropic bicontinuous cubic liquid crystal phases in neat form and/or lyotropic bicontinuous cubic phases with several non-aqueous solvents or water.
