    Författare :Valeria Saavedra; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; water oxidation; charge-separation; photoinduced electron transfer; solar fuel; dye-sensitized;

    Sammanfattning : Conversion of solar energy and its storage in the form of chemical bonds is a current scientific and technological challenge. Different approaches to achieve light-harvesting followed by efficient charge separation are the focus on this thesis. LÄS MER

  3. 7. Zwitterionic Separation Materials for Liquid Chromatography and Capillary Electrophoresis : Synthesis, Characterization and Application for Inorganic Ion and Biomolecule Separations

    Författare :Wen Jiang; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Zwitterionic; stationary phase; separation; liquid chromatography; capillary electrophoresis; sulfobetaine; modification; covalently bonded; graft polymerization; ζ-potential; Analytisk kemi; Analytical chemistry; Analytisk kemi;

    Sammanfattning : Liquid Chromatography (LC) and Capillary Electrophoresis (CE) are modern analytical techniques that play very important roles in many areas of modern science such as life science, biotechnology, biomedicine, environmental studies, and development of pharmaceutics. Even though these two techniques have existed and been subjected to studies for several decades, the developments of new separation materials for them are still very important till now in order to meet the different new demands for improvement from other disciplines in science.

  4. 8. Bioanalytical separation using capillary electrophoresis : Applications with microbubbles and proteins

    Författare :Leila Josefsson; Åsa Emmer; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Background electrolyte; capillary electrophoresis; contrast agents; electroosmotic flow; ethylammonium nitrate; ionic liquids; microbubbles; particles; polyvinyl alcohol microbubbles; and separation; Kemi; Chemistry;

    Sammanfattning : In this thesis the possibilities of using capillary electrophoresis as a separation technique for analysis of proteins and microbubbles is presented.A complete analytical process consists of five necessary steps of which one is the actual analysis step. For this step a suitable analytical technique is needed. LÄS MER

  7. 10. Triboelectric charge characteristics and electrical separation of industrial minerals

    Författare :Hamid-Reza Manouchehri; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Sammanfattning : Despite the fact that triboelectric separation process has not been completely perceived, it pronounced to be environmentally amiable and economically viable for minerals and wastes beneficiation, especially when fine particles with relatively similar electrical properties are being to be separated. Since the method mainly depends on the charges developed on particles for a successful separation, it is necessary to develop different charge polarities on minerals undergoing separation. LÄS MER
