  1. 6. Microphase Separated Cation Conducting Polymers : Design, Synthesis, and Properties

    Författare :Hannes Nederstedt; Centrum för analys och syntes; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Polymer; Litiumbatteri; Mikrofasseparering; Bränslceller; Elektrolyt; Polymerelektrolyt; Polymera bränslecellsmembran; Polymer electrolyte fuel cells; Polymer electrolyte; Polymer electrolyte membrane; Microphase separation; Lithium battery; Polymer; Fuel cell; Proton exchange membrane PEM ;

    Sammanfattning : This thesis describes the synthesis and properties of five different cation conducting polymer systems. These systems were designed so that the polymers would be able to microphase separate into distinct phases with one phase for mechanical strength and one for ionic conductivity. LÄS MER

  3. 7. Design, Synthesis and Thermodynamic Studies of Galectin Ligands

    Författare :Maria Luisa Verteramo; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; galectin; conformational entropy; solvation; thermodynamic; interaction; molecular recognition; thiodigalactoside; diastereomer; structure-based design;

    Sammanfattning : The signaling within and between cells in biology is governed by molecular recognition between natural or synthetic ligands and proteins. This thesis project aimed to investigate the thermodynamic properties of specific interaction between synthetic ligands and galectin proteins. LÄS MER
