  4. 3. On the accuracy of crystal structural analysis and the potential of unraveling structural details by 3D electron diffraction

    Författare :Meng Ge; Xiaodong Zou; Mauro Gemmi; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electron crystallography; three-dimensional electron diffraction; metal-organic framework; open-framework germanates; guest molecules; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : Knowing the atomic crystal structures of ordered porous solids is essential in understanding their behaviors and properties, developing new applications, and designing new porous materials. Electrons have a much shorter wavelength and much stronger interaction with atoms in a crystal compared with X-ray. LÄS MER
