Amorphous phase Mesomorphous phase Nano-crystalline phase Pair distribution function (PDF) X-ray diffraction (XRD) The majority of active pharmaceutical ingredients (APIs) are used as crystalline phase in order to improve their stability and processability. However, drugs are sometimes processed as amorphous to enhance their solubility, stability and performance which are of great interest in the pharmaceutical industry [ 1 ]. Determination of the atomic structure of pharmaceuticals in general and disordered pharmaceuticals in particular at different length scales is an important prerequisite in understanding materials' physical properties. Traditionally, Bragg diffraction methods are the most commonly used techniques to investigate the average ...
