- adj. describing a liquid crystal that exhibits phase transitions as a function of concentration
Sorry, no etymologies found.
As the aqueous concentration of DNA is slowly increased, through evaporation of the aqueous solvent or by dialysis, the macromolecular solution undergoes spontaneous phase transitions to form at least three distinct liquid crystalline phases which are termed lyotropic phase transitions.
This paper deals with the formation in fluidic materials of an intermediate state which is given the term a "lyotropic mesophase system".
LIQUID CRYSTALS: Liquid crystals must be either lyotropic or display thermotropic phases near room temperature.
At DNA concentrations higher than 350 mg / ml, a two-dimensionally ordered columnar hexatic phase is formed, which exhibits a characteristic focal conic texture similar to those seen in both lyotropic and thermotropic liquid crystalline phases with small molecules.
