  4. 28. Structure determination of beam sensitive crystals by rotation electron diffraction : the impact of sample cooling

    Författare :Fei Peng; Junliang Sun; Xiaodong Zou; Dag Nores; Ute Kolb; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electron crystallography; rotation electron diffraction; structure determination; cooling; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : Electron crystallography is complementary to X-ray crystallography. Single crystal X-ray diffraction requires the size of a crystal to be larger than about 5 × 5 × 5 μm3 while a TEM allows a million times smaller crystals being studied. This advantage of electron crystallography has been used to solve new structures of small crystals. LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Adsorbents; Analysis; Cultivation; Determination; Gas chromatography; Identification; Indicator substances; Indoor air; Mass spectrometry; Metabolites; Microbial volatile organic compounds; Optimization; Sampling; Sick buildings; Thermal desorption; Aspergillus versicolor; Cladosporium cladosporioides; Paecilomyces variotii; Pénicillium commune; Phialophora fastigiata; Streptomyces albidoflavus;

    Sammanfattning : Microorganisms are able to produce a wide variety of volatile organic compounds. This thesis deals with sampling, analysis and identification of such compounds, produced by microorganisms commonly found in buildings. LÄS MER

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

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

    Sammanfattning : 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.
