As the concentration of the drops increases further, however, the liquid crystal evolves from
the nematic phase to the «columnar» phase, in which the rods pack together like bundles of straws.
In addition, because the worms are constantly moving and changing their configuration,
this nematic phase is active and far from equilibrium.
Not exact matches
During drying, the Sunset Yellow concentration varied within the drop, and microscope images revealed the formation of different fluid
phases such as the isotropic liquid (random), liquid crystal
nematic (aligned) and liquid crystal columnar (cylindrically packed)
phases that segregate to different regions of the drop.
In this situation, we would say the worms form a
nematic liquid crystal, an ordered
phase similar to the materials used in many flat panel displays.
BaFe2As2 is what is called a «
nematic» crystal because its structure goes through a
phase transition before it becomes superconducting.
At a sufficiently high level of concentration, the rods are pushed close enough together that they begin to align parallel to one another, forming what is known as a «
nematic»
phase.
