  1. 1. Exploring the effects of pressure on the magnetic properties of quasi-low dimensional quantum magnets via thermodynamic measurements

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

    Författare :Emelie Zhu; [2024]
    Nyckelord :Physics and Astronomy; Technology and Engineering;

    Sammanfattning : Four model solid state compounds were used to experimentally investigate the effects of pressure on the interactions in one- and two-dimensional Heisenberg magnetic models. BaCuSi2O6, BaCu2V2O8, SrCuO2 and CuGeO3 were successfully synthesized via solid-state reactions and characterized via x-ray diffraction. LÄS MER

  3. 2. 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

  4. 3. Ion pair chromatography of carboxylic and sulfonic acids with trialkylamines : An investigation of the relationship between the adsorption isotherm of the IPR and the retention factor of the analyte

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Karl Kullberg; [2023]
    Nyckelord :;

    Sammanfattning : Ion pair chromatography has found many uses within analytical chemistry and understanding of the chromatographic process with an ion-pairing reagent have been studied since the 1970s. The adsorption of the Ion-pairing reagent to the stationary phase is understood to be important and many studies have been dedicated to looking at the adsorption isotherms of the earlier quaternary alkylammonium ions.

  5. 4. Design av ångexplosionsreaktor : Utformning av ångexplosionsreaktor för laborativt bruk

    Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Institutionen för naturvetenskap, design och hållbar utveckling (2023-)

    Författare :Jonatan Nordlund; [2023]
    Nyckelord :Steam explosion; pretreatment; biomass; lignocellulose; laboratory use; Ångexplosion; förbehandling; ångbehandling; biomassa; lignocellulosa; laborativt bruk;

    Sammanfattning : Förbehandling av lignocellulosa genom ångexplosion är en förbehandling av biomassa som förändrar strukturen i fibrernas cellväggar. Vid förbehandlingen värms biomassa med mättad ånga under tryck till minst 140 ˚C, detta leder till att flyktiga ämnen avgår från biomassan. LÄS MER

  7. 5. Thermal Analysis of Wave Energy Converter : Developing a Compact CHT Model for Operational Insights

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Jakob Jidbratt; Joel Leckström; [2023]
    Nyckelord :Computational Fluid Dynamics; CFD; Conjugate Heat Transfer; CHT; Wave Energy Converter; WEC; Moving mesh; Ball screw;

    Sammanfattning : Climate change is a critical global issue that continues to shape the way we understand and interact with the world around us. It is discussed more than ever before, especially in politics. LÄS MER
