  1. 6. Gas Chromatographic Method Development for Analysis of Samples from a Carbon Capture Pilot Plant

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :David Wedin; [2024]
    Nyckelord :Carbon Capture and Storage; CCS; AMP DMSO; Gas Chromatography; amine absorption; analysis method development; Chemical Engineering; Chemistry;

    Sammanfattning : In response to the escalating threat of climate change, carbon capture and storage have gained increasing attention as an important component in mitigating the global carbon dioxide emissions. Substantial research efforts have focused on enhancing the energy efficiency and availability of these technologies. LÄS MER

  3. 7. Biologin och naturkunskapens roll i kost- och hälsoundervisning. : En kvalitativ studie om målsättning och undervisningsstrategier från ett gymnasielärareperspektiv.

    Master-uppsats, Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

    Författare :Céline Steib; [2024]
    Nyckelord :Food-related education; adolescents; biology; cross-curricular teaching; integrated curriculum; high-school; Kost- och hälsoundervisning; ämnesövergripande arbete; ämnesintegrerad undervisning; biologi; naturkunskap; gymnasiet; lärarperspektiv;

    Sammanfattning : In Sweden, food-related education is vaguely incorporated in several mandatory high school subjects but not much is known about how it is incorporated in the biology and natural science subjects. This study aimed to understand how Swedish high school biology and natural science teachers approach and contribute to food-related education within and across subjects. LÄS MER

  4. 8. Synthesis of aromatic thiol ligands for the formation of thermoelectric materials

    Master-uppsats, KTH/Kemi

    Författare :Clément Bouchut; [2024]
    Nyckelord :ligand; organic chemistry; organic synthesis; thermoelectric materials; thiol; ligand; organisk kemi; organisk syntes; termoelektriska material; tiol;

    Sammanfattning : I detta arbete så har en uppsättning aromatiska ditiol-ligander framställts (3,5-dimerkaptobensoesyra I, methyl-3,5-dimerkaptobensoat II, 3,5-dimerkaptotoluen III, 4,6-dimerkaptoisoftalaldehyde IV). En trestegssyntes innehållande Newman-Kwart omlagring som nyckelsteg användes för framställning av föreningarna I-III medan förening IV togs fram via en annan syntesväg. LÄS MER

  5. 9. Tau-Leaping Implementations outside of chemistry

    Kandidat-uppsats, Lunds universitet/Statistiska institutionen

    Författare :Lotta Kornö; [2024]
    Nyckelord :Tau leaping; Mathematics and Statistics;

    Sammanfattning : Tau-leaping is an algorithm for model simulations most often used in kinetic chemistry. It was created to make simulations more efficient at the cost of some accuracy. However, its uses outside of chemistry are limited but could help make some model simulations more efficient. LÄS MER

  7. 10. Quantification of Pharmaceuticals at the sub-cellular level using the NanoSIMS

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Analytisk kemi

    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.
