  2. 1. 3D Electron Diffraction : Application and Development towards High-quality Structure Determination

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

    Abstract : 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.

  4. 2. A journey towards complete structure determination of zeolites by electron crystallography methods

    Author : Elina Kapaca; Xiaodong Zou; Philippe Boullay; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electron crystallography; Zeolites; Structure determination; Rotation electron diffraction; Continuous rotation electron diffraction; Disorder; Inorganic Chemistry; oorganisk kemi;

    Abstract : Electron crystallography has recently become very successful for structural studies of materials with sub-micrometer sized crystals. In this thesis two major techniques have been applied for structure elucidation – 3-dimensional electron diffraction (3D ED) and high-resolution transmission electron microscopy (HRTEM) imaging.

  5. 3. 3D Electron Microscopy Methods and Applications : Structures from Atomic Scale to Mesoscale

    Author : Taimin Yang; Xiaodong Zou; Grüne Tim; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 3D Electron microscopy; continuous rotation electron diffraction; structure determination; data quality; electron tomography; mesoporous materials; zeolites; Inorganic Chemistry; oorganisk kemi;

    Abstract : The crystal structure determines the physical properties of a material. The structure can be analysed at different levels, from atomic level, mesoscale level, all the way up to the macroscale level. READ MORE

  6. 4. Detailed structure features from 3D electron diffraction : Heteroatoms, framework disorders, and guest species in zeolites

    Author : Jungyoun Cho; Xiaodong Zou; Tom Willhammar; Miguel Camblor; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; electron crystallography; zeolite; transmission electron microscope; structure determination; oorganisk kemi; Inorganic Chemistry;

    Abstract : 3D electron diffraction (3D ED) has evolved as a powerful method for ab initio structure determination from sub micrometer-sized crystals. It can be used to elucidate the arrangement of atoms in crystalline materials and to provide insights into the laws of nature that govern the properties of matter. READ MORE

  7. 5. Push the limitations of crystal structure determination by 3D electron diffraction : From inorganic porous materials to biomolecules

    Author : Jingjing Zhao; Xiaodong Zou; Hongyi Xu; Tim Grüne; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; electron crystallography; 3D electron diffraction; cryo-EM specimen preparation; structure determination; porous materials; biomolecules; fysikalisk kemi; Physical Chemistry;

    Abstract : Structure elucidation is fundamental to understanding the chemical and physical properties of a material. Three-dimensional electron diffraction (3D ED) has shown great power for structure determination of nanometer- or submicrometer-sized crystals that are either too small or too complex for X-ray diffraction.
