26. Electrochemical properties of alternative polymer electrolytes in fuel cells
Sammanfattning : Fuel cells, using hydrogen as energy carrier, allow chemically‑stored energy to be utilized for many applications, including balancing the electrical grid and the propulsion of vehicles. To make the fuel cell technology more accessible and promote a sustainable energy society, this thesis focuses on alternative polymer electrolytes, as they can potentially lead to a lower cost and a more environmentally‑friendly fuel cell.

28. Characterization of a new amino acid transport system in human epidermal Langerhans cells
Sammanfattning : Based on the discovery of a new amino acid transport system in Langerhans cells (LC), various aspects concerning the L-dopa uptake mechanism into human epidermal LC and the energy metabolism of epidermis have been examined and subsequently characterised. The system lacks any characteristics of other described amino acid transport systems in other cell types. LÄS MER
29. Analysis of Fluorescence Flicker as a Tool to Monitor Proton Transport and Biomolecular Interactions
Sammanfattning : The overall focus of this thesis is on fluorescence flicker processes of fluorescent molecules, e.g. protonation-deprotonation or singlet-triplet electronic state transitions, intrinsic or generated by their interaction with their environment, monitored by fluorescence spectroscopy.

30. Elucidating the molecular basis of Na+/H+ exchange
Sammanfattning : 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. LÄS MER
