  1. Dynamic Anchoring of Nematic Liquid Crystals by Flowing Oil R. Pelcovits, Department of Physics, Brown University G. Crawford, School of Science, Notre Dame University We are using the unique optical properties of nematic liquid crystals to probe the “dynamic anchoring” of the surface of a nematicmicrowell by oil flowing above. Understanding the interaction between the oil and nematic may provide a novel way to construct a petroleum field sensor as well as shed light on fundamental liquid crystal physics. Liquid crystal sensors shown with fluid flow across the open surface at flow rates of (a) 5 mL/min, (b) 10 mL/min, and (c) 20 mL/min. (a) (b) (c)
