Mechanochemical synthesis is an attractive preparative method that combines a green approach with versatility, efficiency, and rapidity of reaction. However, it often yields microcrystalline materials, and their small crystal size is a major hindrance to structure elucidation with conventional single-crystal or powder X-ray diffraction methods. This work presents the novel …

mortar and pestles, sonicators, mixer mills, and vortexers are several of the more common tools used for mechanical and physical disruption. Sample disruption, or homogenization, is not the most exciting methodology to examine, but none-the-less it does have significant impact on the end results of a process. Though used daily and extensively,
