Three-Dimensional Transmission Electron Microscopy: A Novel Imaging and Characterization Technique with Nanometer Scale Resolution for Materials Science
Article Abstract:
First-of-its--kind results are seen from three-dimensional transmission electron microscopy (3D-Tem), effectuated by multiple imaging of a sample combined with image analysis to obtain 3D information with zeolite materials. Virtual cross-sections of the 3D reconstruction of an acid-leached mordenite show the three-dimensional mesoporous channel system (3-20 nm in diameter) is observed with much clarity and definition.

Transmission electron microscopy study of the formation of FAU-type zeolite at room temperature
Article Abstract:
FAU-type zeolite was synthesized at room temperature to study the mechanism of its formation. The processes taking place at the nanometer scale were studied by transmission electron microscopy (TEM) and the crystalline character of the particles observed during the induction period was determined by in situ synchrotron XRD analysis.

Effect of metal coordination on the charge distribution over the cation binding sites of zeolites. A combined experimental and theoretical study
Article Abstract:
Simplified cluster models representing cation bindings sites in a zeolite of ferrierite structure is optimized with a series of divalent and monovalent metal cations. It is observed that the coordination of metal cations significantly perturbs the char ge distribution over the cation binding sites.
