    Sammanfattning : Mass spectroscopy imaging (MSI) has become a vital tool in modern research due to its ability to visualize the spatial distribution of molecules within tissue samples. The collaboration between researchers at AZ, the University of Gothenburg, and Chalmers University of Technology using the NanoSIMS instrument and MSI-SIMS technology has opened up new avenues of exploration in pharmaceutical development, particularly in examining drugs and metabolites at sub-cellular levels.

  3. 7. Beständigheten hos brandimpregnerat trä

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Filip Engström; Hannes Psajd; [2024]
    Nyckelord :Fire retardant treated wood; ISO 5660–1; Permanence; Euroclass; Cone Calorimeter; ConeTools; Infrared spectroscopy; Technology and Engineering;

    Sammanfattning : This report explores the properties of fire-retardant treated wood. This report has investigated the permanence for this material as well as seeing if the process of accelerated aging, which are used to determine the life span of the material, can be comparable to natural aging.

  4. 8. The active phase of Pt(110) during catalytic CO oxidation

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

    Författare :Hira Qazilbash; [2024]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : CO oxidation is an important topic in heterogeneous catalysis, due to its role in industrial processes such as pollution reduction in the auto industry, and ethanol or other fuel production. In the automotive catalytic converters CO oxidation reduces the poisonous CO to CO2 by reacting with O2. LÄS MER

  5. 9. Hyperspectral and multispectral satellite data analysis of nitrogen in grazed and ungrazed tundra in Långfjället, Sweden

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Emma Dahlstedt; [2023-08-18]
    Nyckelord :Hyperspectral imaging; Imaging spectroscopy; Nitrogen; Reindeer; Herbivory; Tundra; Grazing;

    Sammanfattning : Reindeer are a keystone species in the circumpolar north, where they hold great cultural and ecological importance. Continued climate change threatens the long-term sustainability of reindeer husbandry. Reindeer can affect the tundra landscape, influencing the soil nutrient cycling, including the soil nitrogen availability. LÄS MER

  7. 10. FÖRUNDERSÖKNING AV EN EGYPTISK POLYKROM KISTA Dokumentation, tillståndsbeskrivning och analys

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Ida Kingo; [2023-06-15]
    Nyckelord :consolidation; heritage science; ancient Egypt; polychrome coffin; XRF; FTIR;

    Sammanfattning : On ancient Egyptian polychrome art and mainly on coffins, it was normal practice to apply a thick ground and gesso before painting the wood. Sometimes varnish was also applied. Due to fluctuating levels of relative humidity and temperature, the wood swells and shrinks, causing the layers on top of the wood to become damaged. LÄS MER
