  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. Tuning Photovoltaic Properties of Two-dimensional Molybdenum Disulfide by Alloying: An ab initio study

    Master-uppsats, KTH/Materialvetenskap

    Författare :Mochen Li; [2023]
    Nyckelord :Photovoltaic; Molybdenum disulfide; Absorption coefficient; ab initio material design; Fotovoltaisk; Molybdendisulfid; Absorptionskoefficient; ab initio materialdesign;

    Sammanfattning : Addressing the urgent need for innovative energy solutions amidst increasing environmental concerns, the focus on photovoltaic solar cells is intensifying. Currently limited by the Shockley-Queisser limit, conventional silicon-based solar cells offer a maximum power conversion efficiency of 32%. LÄS MER

  4. 3. Robust BECCS deployment strategies under deep uncertainty : A case study of Stockholm Exergi

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

    Författare :Oscar Stenström; [2023]
    Nyckelord :Bioenergy carbon capture and storage; BECCS; decision making under deep uncertainty; DMDU; Dynamic Adaptive Planning; DAP; Robust Decision Making; RDM; Bioenergy carbon capture and storage; BECCS; decision making under deep uncertainty; DMDU; Dynamic Adaptive Planning; DAP; Robust Decision Making; RDM;

    Sammanfattning : The most recent IPCC assessment shows that negative emissions (NEs) and carbon dioxide removal (CDR) technologies are becoming increasingly important in scenarios that limit global warming to 2 °C or lower. In these scenarios, one key set of CDR technologies is bioenergy carbon capure and storage (BECCS). LÄS MER

  5. 4. Återvinning av platinametaller ur fordons katalysatorer : Litteraturstudie om återvinningsprocesser av katalysatorer inom fordonsindustrin med avseende på miljöpåverkan

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

    Författare :Jack Danha; Zahid Abedin; [2023]
    Nyckelord :;

    Sammanfattning : Antalet bilar fortsätter att öka kraftigt i världen vilket skapar stora mängder av utsläpp som orsakar allvarliga miljöproblem. För att minska utsläppet av fordon med förbränningsmotorer används fordons katalysatorer. LÄS MER

  7. 5. Synthesis and characterization of half-sandwich complexes with salicylaldimine ligand derivatives

    Kandidat-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Ujala Mahmud; [2021]
    Nyckelord :Malaria; Plasmodium; Ruthenium; Iridium; Rhodium; Inorganic chemistry; Chemistry;

    Sammanfattning : New half-sandwich complexes of pentamethylcyclopentadienyl-rhodium, iridium, and p-cymene-ruthenium have been synthesized and characterized. All metal complexes contain ligands based on a 4-chloroquinoline framework analogous to the antimalarial drug chloroquine. LÄS MER
