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

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Author : Grigore-Leon Ratiu; [2024]
    Keywords : Physics and Astronomy;

    Abstract : 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. READ MORE

  3. 2. Decay Chains of Fast Alpha Emitters in the Actinide Region

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Author : Tanvir Sayed; [2024]
    Keywords : alpha decay; alpha emissions; fine structure; decay chain; decay scheme; alpha spectrometry; actinide; nucleus; nuclear structure; nuclear states; energy levels; uranium isotopes; U310 experiment; parasitic runs; decay station; TASISpec ; moving window deconvolution; digitisers; alpha-gamma coincidence; 221-Th decay; fine structure of alpha decay to 217-Ra; GSI; Gamow s theory; Geiger-Nuttall; chain search; short half-lives; Physics and Astronomy;

    Abstract : With the advent of increasingly advanced spectroscopic instruments after the turn of the century, it has become accessible to unravel the structure of instantly ‘vanishing’ nuclei, with lifetimes as short as 1 μs, and responsible for pile-up events in analog electronics. Experimental data has been recorded by the Nuclear Structure Group at Lund University for 48Ca/50Ti + nat. READ MORE

  4. 3. Impact of nitrogen availability and nitrogen structural composition on fungal enzymatic activity and growth : how nutrient availability governs response and development of three saprotrophic Basidiomycetes

    University essay from SLU/Dept. of Soil and Environment

    Author : Bella Strid; [2024]
    Keywords : nitrogen; tannins; condensed tannins; MnP; manganese peroxidase; peptidase; saprotrophic basidiomycetes;

    Abstract : Fungi excrete a wide variety of extracellular enzymes to scavenge for nutrients, such as the often scarce yet essential nutrient nitrogen. All fungi produce highly specialized hydrolytic enzymes, e.g. peptidases, that depolymerize organic molecules. READ MORE

  5. 4. Sustainable food packaging based on polyhydroxyalkanoate

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Safana Al-Ashor; [2024]
    Keywords : Biopolymers; Sustainable food packaging; Circular economy; Biobased and biodegradable materials; Food packaging; Processing technologies; Food quality; Shelf-life;

    Abstract : The Norwegian Food Research Institute (Nofima) and the University of Borås worked together to develop this project. The commonly used packaging materials pose a serious threat to the environment, as they are produced from nonrenewable crude oil and cannot decompose naturally. READ MORE

  6. 5. A Novel Method for Measuring Low Energy Excitations with BLS

    University essay from Uppsala universitet/Materialfysik

    Author : Christopher Borchert; [2024]
    Keywords : ;

    Abstract : This report presents the work done on an optical setup combining Raman and BLS spectroscopy and discusses the achieved improvements of the system. After some general optimization and minor redesigning, a new alternative beam path was implemented. READ MORE
