Polymorphism, the ability of a material to adopt different crystal forms, is well documented for many types of materials, including ceramics, metals, and polymers. Ward’s experience in synthesis and characterization of organic solid-state chemistry and polymorphism will be combined with Bilyeu’s expertise in thermal analysis of phase transitions and rearrangements in polymers and Stevens’ experience in x-ray crystallography of biomedical organic and inorganic crystals to develop new methods for the kinetic analyses of solid state polymorphic transitions in organic materials, with an emphasis on the nanoscale.
