Query: Electro-osmosis in nematic liquid crystals   We derive a mathematical model of a nematic electrolyte based on a
variational formulation of nematodynamics. Extending our previous work, we
consider a general setup which incorporates dielectric anisotropy of the
liquid-crystalline matrix and the full set of nematic viscosities. We verify
the model by comparing its predictions to the results of the experiments on the
substrate-controlled liquid-crystal-enabled electrokinetics. In the experiments
a nematic liquid crystal confined to a thin planar cell with surface-patterned
anchoring conditions exhibit electro-osmotic flows along the "guiding rails"
imposed by the spatially varying director.
