  7. 15. 3D Electron Diffraction : Application and Development towards High-quality Structure Determination

    Författare :Yunchen Wang; Wei Wan; Xiaodong Zou; Junliang Sun; Mauro Gemmi; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; three-dimensional electron diffraction; structure determination; rotation electron diffraction; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : Electron crystallography has been proven to be effective for structure determination of nano- and micron-sized crystals. In the past few years, 3D electron diffraction (3DED) techniques were used for the structure solution of various types of complex structures such as zeolites, metal-organic frameworks (MOF) and pharmaceutical compounds.
