Abstract:
Research papers and issued patents involving polymorphism (i.e., crystal systems for which a substance can exist in structures characterized by different unit cells, but in which each of the forms has exactly the same elemental composition) and solvatomorphism (i.e., systems in which the crystal structures of the substance are defined by different unit cells, but wherein these unit cells differ in their elemental composition through the inclusion of one or more molecules of solvent) have been summarized in an annual review. The works cited in this review were published during 2009, and were sourced from the major physical, crystallographic, and pharmaceutical journals. The review is divided into sections that cover articles of general interest, computational and theoretical studies, preparative and isolation methods, structural characterization, properties of polymorphic and solvatomorphic systems, studies of phase transformations, effects associated with secondary processing, and US patents issued during 2009.

Factors Affecting Dissolution: Polymorphism, Amorphism and Pseudopolymorphism
Some polymorphic crystals possess lower aqueous solubility than their amorphous counterparts, leading to incomplete absorption. For instance, the oral suspension of Chloramphenicol, which...

Polymer Classification: Crystallinity
Crystalline domains are the regions where polymer chains are aligned in an orderly manner and held together in proximity by intermolecular forces. For example, chains in the crystalline domains of polyethylene and nylon are bound together by van der Waals...

Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...
