2. 1. Electropermutation assisted by ion-exchange textile : removal of nitrate from drinking water

   Author : Carl-Ola Danielsson; Anders Dahlkild; Mårten Behm; Anna Velin; Gerald Pourcelly; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ion-exchange textile; Ion-exchange membrane; Electropermutation; Electroextraction; Electrodialysis; Electrodeionisation; Modeling; Conducting spacer; Nitrate removal; Water treatment; Water dissociation; Fluid mechanics; Strömningsmekanik;

   Abstract : Increased levels of nitrate in ground water have made many wells unsuitable as sources for drinking water. In this thesis an ion-exchang eassisted electromembrane process, suitable for nitrate removal, is investigated both theoretically and experimentally. READ MORE

4. 2. Aromatic Polymers Functionalized with Anionic and Cationic Groups for Ion Exchange Membranes

   Author : Annika Weiber; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ion exchange membranes; fuel cells; polycondensation; local ion density; poly arylene ether sulfone s;

   Abstract : Fuel cells, redox flow batteries and some water desalination technologies such as reverse osmosis and electrodialysis require efficient ion exchange membranes to perform in an optimum way. Thus, by enhancing the properties of these membranes there is a possibility to improve this type of applications and technologies. READ MORE

5. 3. Diffusion and carrier transport of ions in charged membranes : a comparative study of transport processes and electrical phenomena in solid and liquid ion exchange membranes

   Author : John P. Sandblom; Uppsala universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : .... READ MORE

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

   Author : Pascal F. Meier; David Drew; Simon Newstead; Stockholms universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

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

   Author : Lina Karlsson; Kemiska institutionen; []
   Keywords : 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;

   Abstract : 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. READ MORE
