    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; polymer interlayer; polymer solar cells; stability; conjugated polymers; fullerene derivatives;

    Sammanfattning : Polymer solar cells have emerged as a promising alternative to silicon based solar cells. One of the advantages of polymer solar cells is the possibility to use roll-to-roll techniques for large-scale device production. However, in order to fully utilize this technique, several issues need to be resolved. LÄS MER

  3. 3. Electrochromic Polymer Devices: Active-Matrix Displays and Switchable Polarizers

  5. 5. Development of a polymer based neural probe - How to record intracortical neural activity while minimizing the tissue response

    Författare :Fredrik Ejserholm; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Neural Probes; Electrode Modification; Polymer; Neurophysiology; OSTE ;

    Sammanfattning : Intracortical neural probes have in the last couple of years been developed from stiff single probes to stiff multi-electrode neural probes to flexible multi-electrode neural probes. One reason for the change in design is that more than one recording/stimulation electrode, as in the case with a single wire, is needed for more advanced studies. LÄS MER
