Applications of electron crystallography

Show Summary Details


Several recent and advanced applications of electron crystallography are reviewed. They range from a series of intermetallic compounds solved from electron diffraction data by direct methods and a large number of structures with different complexity solved from electron diffraction data collected using the recently developed automated diffraction tomography (ADT). 3D reconstruction of HRTEM images from several different zone axes are demonstrated on one of the most complex zeolites IM-5 and the first tricontinuous mesoporous silica IBN-9. Combination of electron crystallography and powder X-ray diffraction for structure determination of two zeolite catalysts IM-5 and ITQ-37 is demonstrated. Finally, applications of crystallographic image processing to planar defects in silicate minerals are shown, using so-called artificial crystals, produced by repeating the defect in a crystalline way by image processing. Most of those crystals are nanosized, too small to be studied by single-crystal X-ray diffraction. They are also too complex to be solved by powder X-ray diffraction. Only electron crystallography can handle these nanosized crystals.
