The aging of crystals--i.e., the structural changes which occur in              crystals after nucleation and growth have occurred--will be studied.            During aging, recrystallization occurs rapidly in imperfect crystals of         sparingly soluble materials resulting in significant changes in crystal         habit and purity.  In this study, the aging of terephthalic acid                crystals in water, acetic acid, and DMSO will be experimentally                 examined.  Theoretical studies to attempt to predict the aging rate,            mechanism, and final crystal shape and purity also will be conducted.
