Crystallizing system

The nematic to smectic A phase transition has attracted a great deal of theoretical and experimental interest because it is tire simplest example of a phase transition characterized by tire development of translational order [88]. Experiments indicate tliat tire transition can be first order or, more usually, continuous, depending on tire range of stability of tire nematic phase. In addition, tire critical behaviour tliat results from a continuous transition is fascinating and allows a test of predictions of tire renonnalization group tlieory in an accessible experimental system. In fact, this transition is analogous to tire transition from a nonnal conductor to a superconductor [89], but is more readily studied in tire liquid crystal system. [Pg.2558]

Three different crystallization systems show in values of 2, 3, and 4. Calculate the value required for K in each of these systems so that all will show 6 = 0.5 after 10 sec. Use these m and K values to compare the development of crystallinity with time for these three systems. [Pg.225]
