  1. 16. Stability improvement to a ruthenium catalyst for partial oxidation of methane

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Melker Axelsson; [2023]
    Nyckelord :catalysis; reaction engineering; kinetics; partial oxidation; chemical engineering; Technology and Engineering;

    Sammanfattning : Catalytic partial oxidation of methane (CPOM) is an energy-efficient alternative to steam reforming, the currently prevailing method for energy production from natural gas. Hulteberg Chemistry & Engineering AB has developed a catalyst for the partial oxidation of methane into syngas, for use in solid oxide fuel cells. LÄS MER

    Sammanfattning : Solute carriers consist of over 400 genes and 66 subfamilies and are the largest group of membrane bound transporters. They facilitate movement of many molecules through cells and organelles and are crucial for upholding many key functions in the human body. They are also involved in the pathophysiology of several diseases. LÄS MER

  4. 18. The Impact of Oat and Fruit Consumption on Short-Chain Fatty Acid Production

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Johanna Margaretha Schilder; [2023]
    Nyckelord :short-chain fatty acids; SCFAs; diet; gas chromatography; serum; mice; applied nutrition and food chemistry; Agriculture and Food Sciences;

    Sammanfattning : This study explored the importance of short-chain fatty acids (SCFAs) in maintaining gut health and how different diets affect their levels. Blood plasma and serum samples from mice subjected to two intervention studies on oats and fruits were analysed to determine SCFA concentrations. LÄS MER

  5. 19. Molecular Insights into the Interactions of Monovalent Cations with Highly charged Fatty Acid Monolayers

    Master-uppsats, KTH/Kemi

    Författare :Ran Carlhamn Rasmussen; [2023]
    Nyckelord :VSFS; Langmuir monolayer; ion specific effects; modified Poisson Boltzmann; carboxylic acid; VSFS; Langmuir monolager; jonspecifika effekter; modifierad Poisson Boltzmann; karboxylsyra;

    Sammanfattning : Vibrational sum frequency spectroscopy har använts för att studera interaktionerna mellan monovalenta joner och laddade fettsyramonolager. Subfasen bestod av utvalda alkalihydroxidsaltlösningar med pH12, med huvudfokus på cesiumjonen. LÄS MER

  7. 20. Multiple-Emitter Super-resolution Imaging using the Alternating Descent Conditional Gradient Method

    Kandidat-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Författare :Dolev Illouz; [2023]
    Nyckelord :super-resolution; alternating descent conditional gradient method; ADCG; multiple-emitter localization; nanoscale imaging; single molecule tracking; Physics and Astronomy;

    Sammanfattning : This thesis examines the state-of-the-art 2D super-resolution technique alternating descent conditional gradient (ADCG) method's ability to accurately localize fluorophores in diffraction-limited single molecule images (SMI) and analyze the impact of pre-processing and post-processing modules on ADCG's fluorophore localization. A synthetic dataset obtained from the 2013 Grand Challenge localization microscopy and a temporally linked dataset obtained from an unpublished set of Optical DNA mapping experiments performed by Jonathan Jeffet at the NanoBioPhotonix Lab at Tel-Aviv University were initially segmented to extract their noise parameters.
