Electron tomography and holography in materials science.
The rapid development of electron tomography, in particular the introduction of novel tomographic imaging modes, has led to the visualization and analysis of three-dimensional structural and chemical information from materials at the nanometre level. In addition, the phase information revealed in electron holograms allows electrostatic and magnetic potentials to be mapped quantitatively with hi...
متن کاملElectron localization function in full-potential representation for crystalline materials.
The electron localization function (ELF) is implemented in the first-principles, all-electron, full-potential local orbital method. This full-potential implementation increases the accuracy with which the ELF can be computed for crystalline materials. Some representative results obtained are presented and compared with the results of other methods. Although for crystal structures with directed ...
متن کاملPreparation and Characterization of Superhard Materials of Crystalline Carbon Nitride
13. ABSTRACT (Maximum 200 words) Prompted by the prediction of Cohen and coworkers that beta carbon nitride may have properties similar to diamond, there have been many attempts to synthesize this hypothetical metastable material. We successfully synthesized this material via epitaxial stabilization using TiN(lll) and ZrN(lll) as the growth template. The coatings were CN/TiN or CN/ZrN multilaye...
متن کاملAccurate Characterization of the Pore Volume in Microporous Crystalline Materials
Pore volume is one of the main properties for the characterization of microporous crystals. It is experimentally measurable, and it can also be obtained from the refined unit cell by a number of computational techniques. In this work, we assess the accuracy and the discrepancies between the different computational methods which are commonly used for this purpose, i.e, geometric, helium, and pro...
متن کاملCharacterization and comparison of pore landscapes in crystalline porous materials.
Crystalline porous materials have many applications, including catalysis and separations. Identifying suitable materials for a given application can be achieved by screening material databases. Such a screening requires automated high-throughput analysis tools that characterize and represent pore landscapes with descriptors, which can be compared using similarity measures in order to select, gr...
