Using a magnetic Frederiks transition technique, we measure the temperature and concentration dependences of splay K 1, twist K 2, and bend K 3 elastic constants for the lyotropic chromonic liquid crystal sunset yellow formed through noncovalent reve

The surface alignment of lyotropic chromonic liquid crystals (LCLCs) can be not only planar (tangential) but also homeotropic, with self-assembled aggregates perpendicular to the substrate, as demonstrated by mapping optical retardation and by three-

We report on first successful alignment of a surfactant lyotropic nematic between rubbed glass substrates either clean or spin-coated with a polymer layer. Worsening of the alignment either at small number of rubbings (less than 60), at long time del
