  1. 1. Water assisted CO intercalation underneath Ir(111) supported graphene studied with scanning tunneling microscopy

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

    Författare :Kaivalya Mevada; [2018]
    Nyckelord :Graphene; Intercalation; STM; CVD; TPG; Physics and Astronomy;

    Sammanfattning : Graphene have attracted attention recently due to its unique properties and opportunities for development of high performance carbon based devices. The intercalation, absorption and reactions processes of small molecules above and below the graphene islands hold the key for new perspectives in catalysis, molecular sensors and other technologies.

  3. 3. Katalysatorval och beaktanden vid flerstegsomvandling av glukos till glycerol

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Öyvind Nörregård; [2018]
    Nyckelord :Catalysis; chemical engineering; kemiteknik; Technology and Engineering; Chemistry;

    Sammanfattning : Through hydrogenation of glucose to sorbitol followed by hydrogenolysis of sorbitol to glycerol a pathway to produce bio propane from lignocellulosic material has been confirmed. A wide range of catalyst was tested, in an autoclave batch reactor, to scout the activity of catalysts already proven active, according to previous literature, as well as catalysts not mentioned in literature for the specific reaction.

  4. 4. Characterization of core-shell oxide nanoparticles

    Kandidat-uppsats, SLU/Department of Molecular Sciences

    Författare :Eline Goossens; [2018]
    Nyckelord :magnetic core-shell nanoparticles; characterization; iron oxide; silica;

    Sammanfattning : The growing amount of applications of nanoparticles (NP) have led to concern for their possible harmful effect on human health and the leakage in the environment. Characterization and quantification of the content of NPs are of prime importance, especially methods to relate size, composition and morphology of the particles with the possibility of their detection and quantification.

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

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

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

    Sammanfattning : 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. LÄS MER
