  1. 1. Two facets of Innovation in Engineering Education : The interplay of Student Learning and Curricula Design

    Författare :Anders Berglund; Sofia Ritzén; Martin Edin Grimheden; Margareta Norell Bergendahl; William Ion; KTH; []
    Nyckelord :Engineering education; innovation; design; learning elements; student; change; Ingenjörsutbildning; innovation; design; lärandeelement; student; förändring;

    Sammanfattning : This thesis covers two main perspectives ofinnovation; first, innovation is regarded as an outcome-related mechanism wherelearning is expressed through artefact presentations at the end of adevelopment process; second, innovation comprises a change mechanism in theprocess of student learning, influencing educators to reconsider new methods andpractices. Building on qualitative data from engineering design courses, theaim has been to explore how learning elements in engineering educationinfluence students during early-phase innovation. LÄS MER

  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

    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

  5. 4. Characterizing ions in solution by NMR methods

    Författare :Marianne Giesecke; István Furó; Peter Griffiths; KTH; []
    Nyckelord :electrophoretic NMR; diffusion NMR; NMR imaging; ion pairing; ion association; polyethylene oxide; metal-ion complex; Li ion batteries; electrolyte characterization; Kemi; Chemistry;

    Sammanfattning : NMR experiments performed under the effect of electric fields, either continuous or pulsed, can provide quantitative parameters related to ion association and ion transport in solution.  Electrophoretic NMR (eNMR) is based on a diffusion pulse-sequence with electric fields applied in the form of pulses.

  7. 5. Structural Lithium Ion Battery Electrolytes

    Författare :Niklas Ihrner; Mats Johansson; Daniel Brandell; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Structural batteries; Structural battery electrolyte; Lithium ion batteries; Polymerization induced phase separation; Carbon fibers; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : A major challenge in the electrification of vehicles in the transport industry is that batteries are heavy, which reduces their effectiveness in mobile applications. A solution to this is structural batteries, which are batteries that can carry mechanical load while simultaneously storing energy. LÄS MER
