  1. 1. Continuous electropermutation using ion-exchange textile

    Författare :Carl-Ola Danielsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ion-exchange textile; ion-exchange membrane; electopermutation; electroextraction; Mechanical manufacturing engineering; Mekanisk tillverkningsteknik;

    Sammanfattning : Increased levels of nitrate in ground water has made many wells unsuitable as sources for drinking water. In this thesis an ion-exchange assisted electromembrane process, suitable for nitrate removal, is investigated both theoretically and experimentally. LÄS MER

  4. 3. Elucidating the molecular basis of Na+/H+ exchange

    Författare :Pascal F. Meier; David Drew; Simon Newstead; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; membrane protein; secondary-active transporter; Solute Carrier Transporter; ion-exchange; sodium proton exchanger; potassium proton exchanger; protein structure; cryo-EM; regulation; biokemi; Biochemistry;

    Sammanfattning : Solute carrier (SLC) transporters are membrane transport proteins, which catalyse the movement of nutrients, ions, and drugs across cell membranes. Here, I will present our contribution to understanding the mechanism of the sodium/proton exchangers (NHE), belonging to the SLC9 family of membrane transporters. LÄS MER

  5. 4. Proton-Conducting Polymers and Membranes for Fuel Cells-Preparation and Properties

    Författare :Lina Karlsson; Kemiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymer technology; solution properties; aggregation; state of the water; sulfonation; polyelectrolyte; polymer electrolyte; ionomer; acrylamide copolymer; polyphenylsulfone; polysulfone; water absorption; ion exchange membrane; proton conductivity; Polymerteknik; biopolymers;

    Sammanfattning : The development of new materials for use in fuel cells is of importance for the probable replacement of the combustion engine by this technology in public vehicles in the future. The proton-conducting polymer electrolyte membrane is one of the main components in the fuel cell. LÄS MER

  7. 5. Factors affecting MFI membrane quality

    Författare :Charlotte Andersson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Sammanfattning : Zeolites are crystalline aluminosilicates with molecular sieving properties and are widely used in industrial applications such as catalysis, sorption and ion-exchange. Zeolite membranes are highly interesting due to their capability to continuously separate molecules under severe conditions. LÄS MER
