FOR 143
.~.~ In cholesteric phase (359/105)
DEFINITION
Classification: 349/FOR.143
In cholesteric phase:
Foreign Art Collection wherein the enclosed liquid crystal material is in a mesophase having parallel molecular long axes within a given plane and having the additional characteristic that as one moves to successive planes in a direction perpendicular to the planes, the molecular long axes remain mutually parallel but rotate progressively about the direction of travel.
