  1. 1. Structure Determination and Prediction of Zeolites A Combined Study by Electron Diffraction, Powder X-Ray Diffraction and Database Mining

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

    Author : Peng Guo; Stockholms universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; zeolites; rotation electron diffraction; structure determination; structure prediction; strong reflections approach; oorganisk kemi; Inorganic Chemistry;

    Abstract : Zeolites are crystalline microporous aluminosilicates with well-defined cavities or channels of molecular dimensions. They are widely used for applications such as gas adsorption, gas storage, ion exchange and catalysis. The size of the pore opening allows zeolites to be categorized into small, medium, large and extra-large pore zeolites. READ MORE

  2. 2. Characterization of crystalline materials by rotation electron diffraction Phase identification and structure determination

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

    Author : Yifeng Yun; Stockholms universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; electron microscopy; phase identification; rotation electron diffraction; structure determination; three-dimensional electron diffraction; oorganisk kemi; Inorganic Chemistry;

    Abstract : Electron crystallography is powerful for determination of complex structures. The newly-developed 3D electron diffraction (ED) methods make structure determination from nano- and micron-sized crystals much easier than using other methods, for example X-ray diffraction. READ MORE

  3. 3. 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.

  4. 4. Protein production, characterization and structure determination in structural genomics

    University dissertation from Bioteknologi

    Author : Esmeralda A. Woestenenk; KTH.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; protein production; protein solubility; fusion tags; nuclear magnetic resonance; structure determination; Biologi; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi;

    Abstract : This thesis covers the process from expression of a heterologous gene in Escherichia coli to structure determination of a protein by nuclear magnetic resonance (NMR) spectroscopy.The first part concerns structural genomics-related parallel screening studies on the effect of fusion tags (in particular the His tag) on protein solubility and the use of fusion tags in fast, parallel purification protocols intended for initial biophysical characterization of human proteins produced in E.

  5. 5. From Sequence to Structure Using predicted residue contacts to facilitate template-free protein structure prediction

    University dissertation from Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Author : Mirco Michel; Stockholms universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein bioinformatics; protein structure prediction; contact prediction; machine learning; biokemi med inriktning mot bioinformatik; Biochemistry towards Bioinformatics;

    Abstract : Despite the fundamental role of experimental protein structure determination, computational methods are of essential importance to bridge the ever growing gap between available protein sequence and structure data. Common structure prediction methods rely on experimental data, which is not available for about half of the known protein families. READ MORE
