  2. 1. Towards Single Molecule Imaging - Understanding Structural Transitions Using Ultrafast X-ray Sources and Computer Simulations

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Carl Caleman; Uppsala universitet.; [2007]
    Keywords : Molecular biophysics; XFEL; Ultrafast Melting; InSb; Molecular Dynamics; Water Cluster; Evaporation; Secondary Electron; Photo-cathode; Electron Scattering; Energy Loss Function; Single Particle Imaging; X-ray Diffraction; Water; Ice; KI; CsI; Molekylär biofysik;

    Abstract : X-ray lasers bring us into a new world in photon science by delivering extraordinarily intense beams of x-rays in very short bursts that can be more than ten billion times brighter than pulses from other x-ray sources. These lasers find applications in sciences ranging from astrophysics to structural biology, and could allow us to obtain images of single macromolecules when these are injected into the x-ray beam.

  4. 2. Chirality in Crystal Engineering

    University dissertation from Chalmers University of Technology

    Author : Krister Larsson; Chalmers tekniska högskola.; Chalmers University of Technology.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; crystal engineering; 10; 3-nets; networks; chirality; coordination chemistry; single crystal X-ray diffraction; bis-chelating ligands; hydrogen bonding; 2; 2 -biimidazole;

    Abstract : Crystal engineering combines supramolecular chemistry with solid state chemistry. The goal is to make molecular entities assemble into predefined structures with specific properties. At the same time much research is focused on the understanding of the intermolecular interactions governing the crystallisation process. READ MORE

  5. 3. X-ray structural studies of lanthanide alkoxides

    University dissertation from Stockholm : Institutionen för fysikalisk kemi, oorganisk kemi och strukturkemi

    Author : Marat Moustiakimov; Stockholms universitet.; [2003]
    Keywords : Structural Chemistry; strukturkemi;

    Abstract : A number of homo- and hetero-metallic lanthanide (oxo-)isopropoxides with the general composition LnxMyO(OiPr)p(HOiPr)q has been structurally characterized by means of single crystal X-ray diffraction. The studied compounds may be divided into five groups by the geometry of their metal-oxygen core. READ MORE

  6. 4. Cooperative Lithium-Ion Insertion Mechanisms in Cathode Materials for Battery Applications

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Helen Björk; Uppsala universitet.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Li-ion battery; cathode materials; single-crystal; X-ray diffraction; delithiation; superlattice; phase transformation; charge-ordering; Kemi; oorganisk kemi; Inorganic Chemistry;

    Abstract : Understanding lithium-ion insertion/extraction mechanisms in battery electrode materials is of crucial importance in developing new materials with better cycling performance. In this thesis, these mechanisms are probed for two different potential cathode materials by a combination of electrochemical and single-crystal X-ray diffraction studies. READ MORE

  7. 5. A Crystallographic Study of Platinum(II) Complexes

    University dissertation from Inorganic chemistry

    Author : Karin Lövqvist; Lunds universitet.; Lund University.; [1996]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; Oorganisk kemi; X-ray diffraction; single crystal; structure determination; platinum II ; ligands; trans-influence; cis-influence;

    Abstract : Single crystal structural data have been used to estimate the influence of the X, Y and Z ligands on the Pt‹L bond length in [PtLXYZ] complexes, i.e. the ground state cis- and trans-influence. Cl or S were selected as indicator ligands, L, for these studies. READ MORE
