Drag on particles in a nematic suspension by a moving nematic-isotropic   interface
  We report the first clear demonstration of drag on colloidal particles by a moving nematic-isotropic interface. The balance of forces explains our observation of periodic, strip-like structures that are produced by the movement of these particles.
