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

    University dissertation from Stockholm : Department of Materials and Environmental Chemistry, Stockholm University

    Author : Yunchen Wang; Stockholms universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; three-dimensional electron diffraction; structure determination; rotation electron diffraction; oorganisk kemi; Inorganic Chemistry;

    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.

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

    University dissertation from Stockholm : Department of Materials and Environmental Chemistry, Stockholm University

    Author : Elina Kapaca; Stockholms universitet.; [2020]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electron crystallography; Zeolites; Structure determination; Rotation electron diffraction; Continuous rotation electron diffraction; Disorder; oorganisk kemi; Inorganic Chemistry;

    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.

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

    University dissertation from Stockholm : Department of Materials and Environmental Chemistry (MMK), Stockholm University

    Author : Taimin Yang; Stockholms universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 3D Electron microscopy; continuous rotation electron diffraction; structure determination; data quality; electron tomography; mesoporous materials; zeolites; oorganisk kemi; Inorganic Chemistry;

    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

  4. 4. Development of rotation electron diffraction as a fully automated and accurate method for structure determination

    University dissertation from Department of Materials and Environmental Chemistry (MMK), Stockholm University

    Author : Bin Wang; Stockholms universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; electron crystallography; structure determination; structure refinement; metal-organic framework; guest molecules; software development; automation; hierarchical cluster analyses; high-throughput data processing; data merging; frame orientations; least-squares optimization; data processing; TEM goniometer; oorganisk kemi; Inorganic Chemistry;

    Abstract : Over the past decade, electron diffraction methods have aroused more and more interest for micro-crystal structure determination. Compared to traditional X-ray diffraction, electron diffraction breaks the size limitation of the crystals studied, but at the same time it also suffers from much stronger dynamical effects.

  5. 5. Unraveling the structures of complex nanocrystalline materials by combining TEM and XRPD – development and application

    University dissertation from Stockholm : Department of Materials and Environmental Chemistry (MMK), Stockholm University

    Author : Magdalena Ola Cichocka; Stockholms universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Structure determination; 3D electron diffraction; Complex materials; X-ray powder diffraction; Transmission electron microscopy; oorganisk kemi; Inorganic Chemistry;

    Abstract : Knowledge of the three-dimensional (3D) atomic structure of materials is essential to a fundamental understanding of their properties. The key to understanding the functionality of many materials, particularly those of commercial and industrial interest, is often hidden in the details at the nanoscale. READ MORE
