  1. 1. 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. 2. Can blue mussel shells be used for retrospective 14C-analysis in the marine environment of nuclear power plants?

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Författare :Sofia Bjarheim; [2024]
    Nyckelord :Radionuclide; Marine Environment; Blue Mussels; 14C; Nuclear Power Plant; Physics and Astronomy;

    Sammanfattning : Carbon-14 (14C) is one of the most important contributors to the collective effective dose of the public due to radioactive releases from nuclear power plants. However, the discharge of 14C from nuclear power plants (NPPs) into water has not been measured previously. LÄS MER

  4. 3. Exhaust system for hydrogen fuelled combustion engines: effect of high-water content on the SCR vanadium catalyst

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

    Författare :Cecilia Zambelli; [2023]
    Nyckelord :;

    Sammanfattning : Transportation represents a key secot in the journey towards a greener future, and alternative solutions are needed to meet the decarbonaisation need. Hydrogen internal combustion engines could represent a solution in the short-term, allowing for emission reduction with limited modification to the already existing traditional combustion engines.

  5. 4. Antarctic Subglacial Lakes as Environmental Analogues for Possible Hidden Biospheres on the Moons Europa and Enceladus

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Jonas Fahlman; [2023]
    Nyckelord :astrobiology; icy moons; subglacial lakes; ice dynamics; thermal regimes; extremophiles; anthropogenic contamination; astrobiologi; ismånar; subglaciala sjöar; is-dynamik; termiska regimer; extremofiler; antropologisk kontaminering;

    Sammanfattning : The evolving science of astrobiology for the search for life beyond Earth has put focus on the possibility of subsurface bodies of liquid water beneath the surface of icy moons within our Solar System. Specifically, the Jovian moon of Europa and the Saturnian moon of Enceladus show telling characteristics of endogenous heating through their complex tidal resonances with their parent planets – suggesting the presence of oceans of liquid water and therefore a potential for astrobiology.

  7. 5. Biopolymers processed and used as enzyme carriers

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Dániel Mészáros; [2023]
    Nyckelord :Biobased materials; plasticized sodium alginate; water stability; extraction kinetics; enzyme carrier; Biobaserade material; Mjukgjort natriumalginat; Vattenstabilitet; extraktionskinetik; Enzymbärare;

    Sammanfattning : Syftet med detta masterprojekt var att undersöka möjligheten att använda biobaserat, mjukgjort natriumalginat (NaAlg) som enzymbärare. Alginaterna görs traditionellt bearbetbara genom att tillsätta olika mjukgörare, såsom polyoler (glycerol, sorbitol, etc.), i detta arbete användes glycerol. LÄS MER
