  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. Frequency Stabilization in low Inertia Systems With Battery Power Injections

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Leif Lundin; [2023]
    Keywords : ;

    Abstract : The challenges for the power system of the future becomes increasingly larger when large amountsof renewable energy sources are integrated, and when conventional forms of power such asnuclear power are phased out. This results in a greater difficulty in quickly deploying FrequencyContainment Reserves in the event of of power balance disturbance, to stabilize frequency andvoltage. READ MORE

  5. 4. Improving Product Level Sensing in Filling Tubes

    University essay from Lunds universitet/Innovation

    Author : Hannah Schrewelius; [2023]
    Keywords : level sensing; hygienic design; manufacturing; product development; Technology and Engineering;

    Abstract : This thesis examines the possibility to improve the product level sensing in one of Tetra Pak’s filling machines, because the current solution does not detect this with the desirable precision, as well as measuring range. Today, a magnetic float is used together with 16 separate capacitive sensors. READ MORE

  6. 5. Gate Drive Design for SiC MOSFET Device Characterization : Investigation into the impact of the gate inductance and resistance on the switching behaviour of SiC Power MOSFETs

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Elochukwu Mbah; [2023]
    Keywords : Silicon Carbide Power MOSFET; Gate Inductance; Gate Resistance; Miller Period; dv dt and di dt transients; Double Pulse Test; Kiselkarbid Power MOSFET; Gateinduktans; Gate Resistance; Millerperioden; dv dt och di dt transienter; Dubbelpulstest.;

    Abstract : Silicon Carbide as a wide-bandgap semiconductor has several physical and electrical advantages over Silicon for high voltage and high frequency applications. SiC as a MOSFET device has a lot of great characteristics like lower on-resistance and low input capacitances. READ MORE
