Abstract
The long-standing puzzle of why capillary lengths measured in cellular nema tic-isotropic interfaces are much longer than the value of 0.05 Angstrom pr edicted by Mullins-Sekerka theory has been solved. The resolution of the pa radox is that in confined systems the substrate-nematic anchoring energy co ntributes to the capillary length which is greatly increased by selective a dsorption of ions on the Substrate.
