  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. THE TINY WEIGHT OF EMPTY SPACE

    Master-uppsats, Göteborgs universitet/Institutionen för pedagogik, kommunikation och lärande

    Författare :Maria do Carmo Salgueiro Pinto Antunes; [2023-10-10]
    Nyckelord :Death; Grief; Digitalization; Professional practice; Multimodal literacies;

    Sammanfattning : Purpose: The primary purpose of this study is to display the multimodal literacies embedded in how professionals deal with death and grief within two digitalized professional environments. One is a center for palliative care, in which death is at the center of professional practice. LÄS MER

  4. 3. The chemical evolution of the Milky Way: pushing APOGEE to higher precision and accuracy

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

    Författare :Erik Fridén; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : In the recent decade, a rapid increase in all-sky spectroscopic surveys has occurred, and with it, the wealth of observational data and information on our Galaxy. Consequently, numerous detections of new structures, such as new open clusters, accreted and in-situ components, are discovered. LÄS MER

  5. 4. Reprocessing and Characterization of Polybenzimidazole for High-Temperature Polymer Electrolyte Membrane Fuel Cells

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Douglas Björkengren; [2023]
    Nyckelord :polymer electrolyte membrane fuel cells; PEMFC; HTPEMFC; polymer technology; polymer characterization; reprocessing; recycling; polybenzimidazole; PBI; Technology and Engineering;

    Sammanfattning : A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was successful and the subsequent washing procedure produced PBI that could be redissolved in N,N-dimethyl acetamide (DMAc) and suitable for solution casting of new membranes.

  7. 5. Dagvatten blir badvatten : ett gestaltningsförslag på en baddamm i Gränbyparken med naturlig rening

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Urban and Rural Development

    Författare :Ludvig Pärlefors Prado; [2023]
    Nyckelord :Baddamm; dagvattenrening; naturlig pool; hållbar dagvattenhantering;

    Sammanfattning : Att rena och fördröja dagvatten sker i allt högre grad lokalt. Då dagvattenanläggningarna kommer närmare inpå den bebyggda miljön och i kontakt med stadens invånare, får landskapsarkitekten en viktig roll, genom att utforma öppna dagvattenlösningar. LÄS MER
