WebPhase transitions into and from discotic liquid crystalline states can be called crystallization transitions, since they are associated with the formation of partial or complete translational ordering. The natural order parameters for such transitions can be chosen as the density modulation δρ (r ). WebUpon increasing temperature, melting of solids often occurs as a multi-step process, with mesophases in-between crystalline and fluid phases of matter. Our findings show how natural biological processes can drive transitions in the opposite direction, from disordered fluid to orientationally ordered nematic fluid and solid-like hydrogel states.
