  1. 6. A Planar Laser-induced Fluorescence Study of NO + CO oxidation at Pd(100)

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Hanna Sjö; [2020]
    Keywords : Physics and Astronomy;

    Abstract : Catalysis is an essential tool in industry, and the developments in catalysis research during the last decades have led to higher efficiency in many important processes. CO oxidation is a common reaction to use in catalysis research both due to its applications in industry but also since it is a simple reaction where the knowledge gained about its reaction mechanism can be applied to important but more complicated reactions.

  3. 7. In Vitro Evaluation of Laser Induced Fluorescence for Aided Caries Excavation (FACE)

    University essay from Malmö universitet/Odontologiska fakulteten (OD)

    Author : Mattias Tagesson; Hedvig Olsson; [2019]
    Keywords : ;

    Abstract : Syfte: att utvärdera tillförlitligheten hos laserinducerad fluorescens som hjälpmedel vid kariesexkavering (FACE), och om FACE kan användas som ett komplement till befintliga kliniska diagnostiska metoder för att bestämma när kariesskadan är färdigexkaverad.Material och metod: två experimentprotokoll utvecklades.

  4. 8. Calibration of Quenching for laser-induced fluorescence of CO₂ at 2.7 μm

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Philip Stjärneblad; [2019]
    Keywords : Laser-induced fluorescence; CO oxidation; Catalysis; Fluorescence quenching; Calibration; Physics and Astronomy;

    Abstract : Knowledge about the gas-phase close to an active catalyst is essential in order to understand the properties of the catalytic reaction process. By the use of planar laser-induced fluorescence (PLIF), the gas-phase can be visualized with high spatial and temporal resolution without affecting the catalyst. READ MORE

  5. 9. Characterization of biomass pyrolysis and gasification using Raman Spectroscopy

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Henrik Johansson; [2018]
    Keywords : Raman; Raman Spectroscopy; Raman scattering; biomass; biofuel; thermal conversion; pyrolysis; gasification; laser diagnostics; laser-induced fluorescence; LIF; energy; wood pellets; ammonia; aldehydes; ketones; formaldehyde; acetaldehyde; acetone; combustion physics; Physics and Astronomy;

    Abstract : This thesis examines the emissions formed during pyrolysis and gasification of lignocellulosic biomass in pellet form, using vibrational Raman spectroscopy. Seven different samples are studied during the pyrolysis process and six of these are also studied during gasification. READ MORE

  6. 10. CO and CO2 Detection for Catalysis Diagnosis by Means of PLIF

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Sebastian Pfaff; [2017]
    Keywords : plif; laser diagnostics; catalysis; carbon monoxide; carbon dioxide; palladium; planar laser induced fluorescence; Physics and Astronomy;

    Abstract : In order to fully understand the underlying processes of catalysis, it is vital to combine measurements of the catalyst surface, where the reaction occurs, with measurements of the gas concentration close to the catalyst. We have developed a convenient setup, which uses a single laser system to visualise the gas surrounding a working catalyst in situ at realistic operating conditions. READ MORE
