  1. 1. Coke on Supported Palladium and Platinum Catalysts

    Författare :Mikael Larsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TPO; palladium; deactivation; coke; propane dehydrogenation; microbalance; vegetable oil hydrogenation; acetylene hydrogenation; catalysis; platinum;

    Sammanfattning : Catalyst deactivation by coke formation has been investigated in three heterogeneous catalytic processes, propane dehydrogenation, acetylene hydrogenation and hydrogenation of vegetable oil. Palladium and/or platinum supported on alumina were used as catalysts in all reactions. LÄS MER

  5. 4. On the Frequency and Q Factor Response of the Quartz Crystal Microbalance to Liquid Overlayers

    Författare :Michael Rodahl; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; piezoelectric effect; solid-liquid interface; sensors; protein adsorption; QCM; tribology; quartz crystal microbalance;

    Sammanfattning : The quartz crystal microbalance (QCM) is an ultra-sensitive weighing device. It consists of a piezoelectric quartz crystal, often in the form of a disk, which is sandwiched between a pair of evaporated electrodes. LÄS MER

  7. 5. Self Assembled Monolayers for Quartz Crystal Microbalance based Biosensing

    Författare :Annica Myrskog; Bo Liedberg; Sofia Svedhem; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : The work in this thesis has been focused on developing surfaces for use in biosensor systems, especially for quartz crystal microbalances. The surfaces were prepared by adsorption of organosulfur molecules onto gold substrates, so called self assembled monolayers (SAMs). LÄS MER
