    Sammanfattning : The Polymer Electrolyte Membrane Fuel Cell (PEMFC) is a promising energy converting technology for powering automotives and electrical equipment using hydrogen gas as fuel and producing water as the only exhaust. The active carbon-supported platinum catalyst present in the electrodes limits the maximum power generation in state-of-the-art PEMFCs due to platinum’s poor activity for the oxygen reduction reaction (ORR) taking place at the cathode.

  3. 2. lnterfacial Design and Characterization of Oligo(ethylene glycol) Self-Assembled Monolayers : Templates for Biomolecular Architectures

    Författare :Ramūnas Valiokas; Stephen D. Evans; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis presents efforts to better understand and control the interfacial properties of oligo(ethylene glycol)-containing self-assembled monolayers (OEG SAMs) on gold. This has been done by means of molecular and interfacial design, followed by extensive characterization of the SAMs using a variety of surface analytical techniques. LÄS MER
