    Backgrounds

    Crystalline state of pharmaceutical materials is of great importance in preparation of pharmaceutics, because their physicochemical properties affect bioavailability, quality of products, therapeutic level, and manufacturing process. Although X-ray powder diffractometry (XRPD) is widely used, the usage of X-ray should be taken into..
