CRYSTAL GROWTH & DESIGN 2008 VOL. 8, NO. 1 2
Editorial Editorial: Facets of Polymorphism in Crystals Nearly two centuries after its formulation, the concept of crystal polymorphism is taking hold to the point that it is moving into the consciousness of those outside the field. The reasons for this turn of events are well highlighted by the articles in this special issue on “Facets of Polymorphism in Crystals”. There is clearly a need for continued exploration of this old problem with increased rigor and indeed for reevaluation of some of the fundamental concepts. Although the economic impact of this phenomenon is most obvious when considering pharmaceuticals, activity related to crystal polymorphism in energetic materials, pigments, and commodity chemicals is also on the upswing. As science and engineering advance, there is a greater demand for control over processes, and crystal polymorphism often frustrates attempts at prediction and control. This driving force coupled with increasing sophistication in polymorph production, identification, and prediction methodologies ensures continued growth in activity and the future vitality of the field. This is the third time that Crystal Growth & Design has devoted a topical issue to crystal polymorphism, and the present collection is a good reflection of the breadth of activities taking place internationally.
