(4) Chiral nematic film made from CNC suspension.
Evaporating suspending liquid of chiral nematic phase under a magnetic
field, we obtain chiral nematic film of CNC which forms a monodomain as
shown by a photo (bottom right), while multidomain is obtained without
magnetic field (top left). [Sci. Technol. Adv. Mater., 9, 024212 (2008)]
