  1. 1. Linking the selectivity of varying surface phases of a real palladium catalyst toward specific methane oxidation pathways with Ambient Pressure X-ray Photoelectron Spectroscopy

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

    Författare :Ulrike Küst; [2023]
    Nyckelord :APXPS; catalysis; palladium; methane; Physics and Astronomy;

    Sammanfattning : The study of heterogeneous catalysis, especially within methane oxidation, is of high importance in order to more efficiently remove unburned methane from bio-fuel exhausts. This is relevant as bio-fuel engines will replace those driven by fossil fuels in the coming decades. LÄS MER

  3. 2. Hypoxic Target Volume Determination in PET/CT Imaging : The Impact of Deformable Image Registration

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Viktor Rosenberg; [2022]
    Nyckelord :Positron emission tomography; image registration; hypoxic tumour volume; dose escalation; tumour control probability;

    Sammanfattning : Using a tailored dose distribution for personalized radiotherapy with the help of positron emission tomography (PET) might give an edge for successful tumour elimination. One of the main determinants for tumour radioresistance in several solid tumours has been investigated as hypoxia, including head and neck cancer (HNC). LÄS MER

  4. 3. Preanalytisk hållbarhetsstudie för analys av vB-Standardbikarbonat

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Författare :Lukas Rydhage; [2022]
    Nyckelord :Standardbikarbonat; Preanalys; Preanalytisk provhantering; Syra-basreglering;

    Sammanfattning : Standardbikarbonat innebär koncentrationen bikarbonat i plasmadelen av helblod under standardiserade förhållanden. Analysen baseras på uppmätta värden av partialtryck för koldioxid (CO2), pH, syrgasmättnad och total-hemoglobin samt en beräkning. LÄS MER

  5. 4. Partial hydrodeoxygenation of a heavy bio-based oil fraction : (A technical feasibility study)

    Master-uppsats, KTH/Kemiteknik

    Författare :Akshay Menon; [2020]
    Nyckelord :Hydrodeoxygenation; Tall oil pitch; oxygen removal; sulphidation; catalyst;

    Sammanfattning : This report is intended to provide the reader with an extensive background information on hydrode oxygenation (HDO) of Tall Oil Pitch (TOP), combined with results from chemical property analyses of the same. Firstly, the importance of hydrogenation and oxygen removal for a biomass-based feed material is highlighted. LÄS MER

  7. 5. Factors influencing the generation of carbon monoxide in fires partially suppressed through water mist application

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Haydn Lewis; [2020]
    Nyckelord :Fire safety engineering; water mist; fire suppression; carbon monoxide; water; combustion; Technology and Engineering;

    Sammanfattning : Fires in the built environment typically consist of diffusion flames with inefficient mixing of fuel and oxygen, resulting in a degree of incomplete combustion and the generation of carbon monoxide. Fire suppression systems, used to control the growth and spread of fire, influence the combustion reaction process. LÄS MER
