  1. 1. Development and understanding of a model V2O5/anatase TiO2(101) SCR catalyst

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

    Författare :Johanna Paulsson; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : A model V2O5/ anatase TiO2(101) SCR catalyst is studied with the purpose of developing and understanding the reaction mechanism through which this catalyst reduces NOx. Several reaction mechanisms have been proposed for this catalyst in the past, but there is still no agreement on which of these describe the reaction the best, if any. LÄS MER

  3. 2. Dependence of Degradation Mechanisms in Magnesium Alloys on Grain Orientation and Interfaces in 3D

    Master-uppsats, Lunds universitet/Materialteknik

    Författare :Johan Ranstad; [2023]
    Nyckelord :Mg-Zn alloys; Diffraction contrast tomography; Isothermal Calorimetry; Immersion testing; Corrosion Rate; Microgalvanic coupling.; Technology and Engineering;

    Sammanfattning : Magnesium alloys are promising candidates as biomedical implants. However, a good understanding of their degradation processes is lacking. In this work, degradation in two magnesium alloys were studied in a simple physiological-fluid electrolyte of H2O+0.9wt%NaCl, Mg-5wt%Zn (Z5) & Mg-5wt%Zn-0. LÄS MER

  4. 3. LAMP on disk

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Joud Toumeh; [2023]
    Nyckelord :;

    Sammanfattning : Projektet har startat med ett samarbete med SciLifeLab forskning center vid Karolinska institutet där den Nano- biologiavdelningen har tagit fram en kemisk reaktion som kunde detektera Covid-19 metoden heter LAMP som står för Loop- mediated isothermal amplification. Den befintliga enheten som labbet har utvecklat används med hjälp av en mobiltelefon som tar bilder på proverna inför analys. LÄS MER

  5. 4. Rare Earth Triflate/Alanine Catalysed Diels-Alder and Michael Reactions in Water and an Alternative Pyrrole Synthesis

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Albin Olsson; [2022]
    Nyckelord :Water; Green Chemistry; Synthesis; Organic Chemistry; Chemistry;

    Sammanfattning : Large amounts of organic solvents are used within the field of chemistry and nearly everything is being discarded and is not reused. A way to reduce the environmental impact that this leads to is to use a safe and natural solvent that is easy to access, like water. LÄS MER

  7. 5. Lejarfjället Garnet(?) Peridotite – Origin and Petrological Characterization of Symplectitic Aggregates in Ultramafic Rocks

    Kandidat-uppsats, Uppsala universitet/Mineralogi, petrologi och tektonik

    Författare :Felicia Eriksson; [2022]
    Nyckelord :ultramafic; high-pressure metamorphism; peridotite; garnet breakdown; Scandinavian Caledonides; ultramafisk; högtrycks metamorfos; peridotit; granat; skandinaviska kaledoniderna;

    Sammanfattning : Ultramafic rocks are abundant in the Earth’s mantle but rare on the surface. Since no in-situ samples from the mantle can be collected, mantle rocks provide knowledge of mechanisms operating in the mantle and large-scale processes that brought them up to the surface. LÄS MER
