Pharmaceutical co-crystal formation represents a straightforward way to dramatically influence the solid-state properties of a drug substance, particularly its solubility and hence bioavailability. This short review summarises this highly topical field, covering why the topic is of interest in pharmaceutical formulation, the definitions and practical scope of co-crystals, co-crystal preparation...

The striking resemblance of the rhombohedral and monoclinic forms of the title molecule to beta- and gamma-quinol provides a crystal engineering approach to new polymorphic systems.

PATTERN INFORMATION EXTRACTION FROM CRYSTAL STRUCTURES Erhan Okuyan M.S. in Computer Engineering Supervisor: Assist. Prof. Dr. Ug̃ur Güdükbay December, 2005 Determining crystal structure parameters of a material is a quite important issue in crystallography. Knowing the crystal structure parameters helps to understand physical behavior of material. For complex structures, particularly for materi...
