  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. Development of a guide system for free neutron oscillation searches at the European Spallation Source

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska Högskola; Lunds universitet/European Spallation Source ESS AB

    Author : Linnéa Björk; [2023]
    Keywords : ESS; neutrons; dark matter; antimatter; neutron guides; Physics and Astronomy;

    Abstract : In this project, a neutron delivery system for the study of free neutron oscillations at the HIBEAM beamline at the European Spallation Source (ESS) has been developed. The HIBEAM experiment is part of a two-stage program at ESS which will address open questions in physics; specifically the nature of dark matter and the observed asymmetry between matter and antimatter in the Universe.

  4. 3. Flight to climate: liquidity commonality in brown equities

    University essay from Stockholms universitet/Företagsekonomiska institutionen

    Author : Haiping Yu; [2023]
    Keywords : ESG; ESG Investing; Climate investing; Liquidity Commonality; Systematic Liquidity Risk;

    Abstract : Emerging ESG studies have established a negative equilibrium correlation between ESG factors and stock returns in an economy predominately influenced by investors with nonpecuniary preference over high ESG credentials. However, little research has delved into a potential systematic liquidity risk phenomenon associated with aggregate trading activities of ESG-motivated investors who share a common nonzero ESG preference component in their utility function.

  5. 4. Digitally Controlled Oscillator Topologies for mm-Wave Pulsed Coherent Radar

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Klas Junskog; [2023]
    Keywords : oscillators; mm-wave; radar; Technology and Engineering;

    Abstract : The advancement of future generations of wireless communication and radar sensing warrants the need for mm-wave digitally controlled oscillators (DCOs) with high-frequency trade-offs in consideration. The purpose of this project is to investigate DCO topologies inspired from scientific literature. READ MORE

  6. 5. Stray capacitance study for HVDC Classic : The use of PSCAD and Mathcad to calculate the equivalent stray capacitance

    University essay from Uppsala universitet/Elektricitetslära

    Author : Saga Dalersand; Fredrik Gjöthlén; [2023]
    Keywords : ;

    Abstract : The reactors placed in the thyristor valve designed by Hitachi Energy have reactor losses which are dependent on the stray capacitance. To find out the stray capacitance, and further get to know the reactor losses, a PSCAD simulation is performed. READ MORE
