  1. 1. Fabrication and Characterization of Nano-Confined Pd Catalysts for CO Oxidation

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Alfred Larsson; [2019]
    Nyckelord :Catalysis Palladium Nano Nanopore CO oxidation; Physics and Astronomy;

    Sammanfattning : During this thesis nanoporous alumina has been used as a template for the synthesis of nano-confined palladium structures. The nanoporous templates have been synthesized by anodization of aluminum and characterized using atomic force microscopy (AFM), scanning electron microscopy (SEM) and small angle X-ray scattering (SAXS), resulting in good statistics of the pore diameter and interpore distance of these nanoporous structures.

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

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

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

    Sammanfattning : 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. LÄS MER

  3. 3. Fabrication and Evaluation of Perovskite LaCrO3 Nanoparticles as Catalyst for Electrochemical Ammonia Synthesis

    Master-uppsats, Lunds universitet/Institutionen för Energivetenskaper

    Författare :Mathilda Ohrelius; [2019]
    Nyckelord :nitrogen reduction reaction; electrochemical ammonia synthesis; catalyst; perovskite; LaCrO3; fuel cell; renewable energy; Science General;

    Sammanfattning : As our way of living exploits the resources of the earth and our energy use keeps on increasing, we are now facing a climate crisis never seen before in modern time. To face these consequences and try to ease the harm we need to transform our extraction and use of energy. LÄS MER

  4. 4. MAGNETIC CHARACTERIZATION OF SELF-ASSEMBLED ONE-DIMENSIONAL NETWORKS OF MAGNETIC NANOPARTICLES

    Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen
