  1. 1. Application of Fourier Transforms to time-resolved ambient pressure spectroscopy operando studies of CO oxidation over Pt(111)

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

    Författare :Grigore-Leon Ratiu; [2024]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The study of heterogeneous catalysis has important implications in increasing the efficiency of industrial processes and in reducing the emissions of greenhouse gases from sources such as automobiles. A reaction with high industrial relevance is the oxidation of CO on noble metal catalysts. LÄS MER

  3. 2. Desiccant Dehumidifier Reactivation Stream : Unlocking Waste Heat Recovery Potential

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Fanny Bleckur; [2023]
    Nyckelord :;

    Sammanfattning : Northvolt is committed to developing the world’s greenest battery. To achieve this,energy-efficient production processes are essential and dehumidification is a crucial, yet energy-intensive, process for battery production. 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. High Temperature Tribology of Exhaust Components in Alternative Fuel Engines

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Muhammad Hashir Zaheer; [2023]
    Nyckelord :High temperature tribology; Wear; Friction; Exhaust manifold; Lip seal ring; Wear resistant coatings; Inconel 718c; SiMo51 ductile cast iron; AlTiN; Tribaloy 400;

    Sammanfattning : Internal Combustion Engine (ICE) exhaust components are exposed to extreme operating temperatures. Thus, it is necessary that they are designed with materials that can sustain thermal and vibrational stresses. LÄS MER

  7. 5. Mäta HRR från Li-jonbatterier med hjälp av OCC (oxygen consumption calometry) och andra metoder

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Olof Skyllberg; [2023]
    Nyckelord :Litium-jon batteri; Termisk rusning; Oxygen consumption calorimetry OCC ; Sensible enthalpy rise approach SERA ; effektutveckling. Lithium-ion batteries; Thermal runaway; Heat release rate.; Technology and Engineering;

    Sammanfattning : One of the most important parameters to measure in the fire discipline is the heat release rate (HRR). Therefore it is very important that these measurements are accurate and as correct as possible. The most common method for measuring heat release rate of fires is the OCC method (oxygen consumption calorimetry). LÄS MER
