  1. 1. New Electrochemical Tools to Study Exocytosis

    Författare :Joakim Wigström; Chalmers University of Technology; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amperometry; QCM-D; micro electrode array; large dense core vesicles; chromaffin cells; PC-12 cells; microelectrode; exocytosis; electrochemical cytometry; electrochemical imaging; acetylcholine; endocytosis; nanoparticles; enzyme biosensor; microfabrication;

    Sammanfattning : The work described in this thesis has the focus on the development of new analytical tools to study processes related to cellular secretion (exocytosis) in cell models. Four novel techniques were developed, allowing new ways to study processes related to exocytosis, and gain previously unattainable knowledge. LÄS MER

  2. 2. Imaging surface plasmon resonance

    Författare :Olof Andersson; Bo Liedberg; Fredrik Björefors; Thomas Ederth; Jiří Homola; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Chemistry; Kemi;

    Sammanfattning : The central theme of this thesis is the use of imaging Surface Plasmon Resonance (iSPR) as a tool in the characterization of surfaces with laterally varying properties. Within the scope of this work, an instrument for iSPR analysis was designed and built. LÄS MER

  3. 3. Electrochemical Studies of Aging in Lithium-Ion Batteries

    Författare :Matilda Klett; Göran Lindbergh; Charles Delacourt; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; aging; EIS modeling; electrolyte characterization; graphite; hybrid electric vehicles; impedance spectroscopy; LiFePO4; Li-ion batteries;

    Sammanfattning : Lithium-ion batteries are today finding use in automobiles aiming at reducing fuel consumption and emissions within transportation. The requirements on batteries used in vehicles are high regarding performance and lifetime, and a better understanding of the interior processes that dictate energy and power capabilities is a key to strategic development.

  4. 4. Electrochemical and microscopic analysis of chemical signalling in biological systems

    Författare :Anna Larsson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []

    Sammanfattning : Cellular communication is a prerequisite in multicellular organisms in order to survive. Many times, this communication occurs through the highly controlled and regulated release of chemical signals through a process known as exocytosis. LÄS MER

  5. 5. 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.
