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

   Författare :Carl-Ola Danielsson; Anders Dahlkild; Mårten Behm; Anna Velin; Gerald Pourcelly; KTH; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

4. 3. Performance of Conventional and Structural Lithium-Ion Batteries

   Författare :Maria Hellqvist Kjell; Göran Lindbergh; Mårten Behm; Anthony Kucernak; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Lithium-ion batteries have, in recent years, experienced a rapid development from small everyday devices towards hybrid electric vehicle (HEV) applications. Due to this shift in application area, the battery performance andits degradation with time are becoming increasingly important issues to besolved. LÄS MER

5. 4. Battery Health Estimation in Electric Vehicles

   Författare :Verena Klass; Göran Lindbergh; Mårten Behm; Anna Stefanopoulou; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium-ion battery; state-of-health; electric vehicle; support vector machine; resistance; capacity; Chemical Engineering; Kemiteknik;

   Sammanfattning : For the broad commercial success of electric vehicles (EVs), it is essential to deeply understand how batteries behave in this challenging application. This thesis has therefore been focused on studying automotive lithium-ion batteries in respect of their performance under EV operation. LÄS MER

7. 5. Influence of fluid shear on primary nucleation of low molecular organic compounds in solution

   Författare :Jin Liu; Åke Rasmuson; Mårten Behm; Ulf Gedde; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Agitation; Primary nucleation; Induction time; Fluid shear; Energy input; Mass transfer; Molecular alignment; Butyl paraben; Curcumin; m-Hydroxybenzoic acid; Solid-liquid interfacial energy; Nuclei critical radius;

   Sammanfattning : In this project, two experimental systems have been set up to study the influence of fluid shear on primary nucleation. In the first set of experiments, in total about 3000 nucleation experiments have been done with butyl paraben/ethanol solutions, curcumin/ethanol solutions and m-hydroxybenzoic acid/1-propanol solutions in capped vials agitated with magnetic stir bars.
