Abstract
The goals of this research are: (i) to study the effects of the rate of supersaturation on crystallization kinetics and polymorph selectivity; and (ii) to develop a generalized phase diagram from first principles and verify its applicability to a wide range of molecular solutions. This thesis investigates how the rate of supersaturation affects macroscopic phase transitions and final crystal properties and how the microscopic particle interactions influence both the equilibrium solution phase behavior such as solubility boundary and the nonequilibrium phase transitions such as liquid-liquid phase separation and gel formation.
