  1. 1. Micro-Flow Reactors for Kinetic Studies of Model Catalysts made by Electron-Beam Lithography

    Författare :Stefan Johansson; Chalmers University of Technology; []
    Nyckelord :bistability; catalysis; nano-fabrication; supported model catalyst; CO oxidation; electron-beam lithography EBL ; micro-reactor;

    Sammanfattning : The main objective of this work is to explore the potential of using electron beam lithography (EBL) to prepare well defined supported model catalysts, which can be used for catalytic research. The work has involved three major areas (i) EBL-fabrication of catalysts, (ii) design of a micro-flow reactor for catalytic evaluation, and (iii) problem oriented research using EBL-fabricated model catalysts.

  4. 3. Fuel Reforming for Hydrogen Production in Heavy-Duty Vehicle Applications

    Författare :Moa. Z. Granlund; Lars. J. Pettersson; Robert J. Farrauto; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; aging · autothermal fuel reforming · CeO2-ZrO2 · characterization · diesel · H2-assisted HC-SCR · micro reactor · monolith; Chemical Engineering; Kemiteknik;

    Sammanfattning : The depletion of fossil fuels together with growing environmental concerns have created incitement for developing a more energy-efficient and environmentally-friendly vehicle fleet. The development towards cleaner heavy-duty vehicles started already in the 80’s with the introduction of emission legislations. LÄS MER

  5. 4. Sample Handling Techniques in Biological and Environmental Applications Emphasizing Biomolecular Recognition and MALDI-TOF MS

    Författare :Patrik Önnerfjord; Reumatologi och molekylär skelettbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; protein identification; microchip IMER; microdispensing; MALDI-TOF MS; fluorescence polarization; flow immunoassay; pesticide immunoassays; phenol biosensor; restricted access media; SPE; Analytical chemistry; Analytisk kemi;

    Sammanfattning : The use of restricted access media and other stationary phases for clean-up and trace enrichment of environmental samples coupled on-line to liquid chromatography using diode array detection as well as thermospray MS is described. This on-line configuration was compared with commercially available ELISAs for the determination of triazines in complex matrices, showing superior precision and accuracy with the chromatographic method.

  7. 5. Amperometric Carbon Paste Biosensors Based on Horseradish Peroxidase and Oxidases

    Författare :Vijayakumar Rajendran; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; on-line monitoring; l-lactate; glucose; ethanol; Biosensor; Carbon paste; Analytisk kemi;

    Sammanfattning : Amperometric carbon paste peroxide sensors based on horseradish peroxidase (HRP) were developed. In the first approach, HRP was chemically modified with polyethylene glycol to improve the stability of the enzyme in the organic paste matrix and compared with native HRP electrode. LÄS MER
