  1. 1. Open-Framework Germanates : Synthesis, Structure, and Characterization

    Författare :Andrew Kentaro Inge; Xiaodong Zou; Anthony Cheetham; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Open-framework; zeolites; germanates; porous materials; crystallography; hydrothermal synthesis; crystal structure; Structural Chemistry; strukturkemi;

    Sammanfattning : Novel open-framework germanates and open low-dimensional structures were synthesized and characterized. Their crystal structures were solved by single crystal X-ray diffraction or X-ray powder diffraction combined with other techniques. LÄS MER

  3. 2. Visualizing structural dynamics: from small molecules to membrane proteins

    Författare :Magnus Andersson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; membrane protein; bacteriorhodopsin; proteorhodopsin; halorhodopsin; structural dynamics; time-resolved X-ray scattering;

    Sammanfattning : To fully understand the mechanism of a chemical reaction, it is important to characterize the rapid structural dynamics of transient chemical species as the reaction propagates. Since chemical processes are heavily influenced by the solvent in which they occur, the interaction with the surrounding solution also needs to be elucidated. LÄS MER

  4. 3. Structural assessment procedures for existing concrete bridges : Experiences from failure tests of the Kiruna Bridge

    Författare :Niklas Bagge; Björn Täljsten; Paulo Cruz; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anchorage; carbon fibre reinforced polymers; concrete; existing bridges; finite element analysis; flexure; full-scale test; load-carrying capacity; residual prestress force; punching; safety verification; shear; structural assessment; structural behaviour; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Assessing existing bridges is an important task in the sustainable management ofinfrastructure. In practice, structural bridge assessments are usually conducted usingtraditional and standardised methods, despite knowledge that these methods oftenprovide conservative estimates. LÄS MER

  5. 4. Open-Framework Germanates : Crystallography, structures and cluster building units

    Författare :Kirsten Elvira Christensen; Xiaodong Zou; Osamu Terasaki; Angeles Monge; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; germanate; crystallography; building unit; zeotype; scale chemistry; Chemistry; Kemi; strukturkemi; Structural Chemistry;

    Sammanfattning : This thesis is focussing on the crystallographic challenges and what knowledge we can gain from studying the different open-framework germanates. Five new open-framework germanates have been synthesized and the structures have been determined by single crystal X-ray diffraction. LÄS MER

  7. 5. Crustal architecture of the Kiruna mining district : Structural framework, geological modeling, and physical rock property distribution

    Författare :Ervin Csaba Veress; Tobias Bauer; Stefan Luth; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kiruna mining district; geological modeling; structural framework; common earth modeling; petrophysical characterization; mineral exploration; iron oxide-apatite; Ore Geology; Malmgeologi;

    Sammanfattning : Rapid technological advancements and growing environmental consciousness created a shifting dynamic of metal demand within the context of contemporary global challenges. The metals play a pivotal role in this transformation and remarkable surge in demand is expected. LÄS MER
