title: Anomalous capillary length in cellular nematic-isotropic interfaces.
abstract: The long-standing puzzle of why capillary lengths measured in cellular nematic-isotropic interfaces are much longer than the value of 0.05 A predicted by Mullins-Sekerka theory has been solved. The resolution of the paradox is that in confined systems the substrate-nematic anchoring energy contributes to the capillary length which is greatly increased by selective adsorption of ions on the substrate.
