  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. Tuning electrolyte-electrode interphases for low-temperature Li-ion batteries

    University essay from Uppsala universitet/Strukturkemi

    Author : Robin Xu; [2023]
    Keywords : Li-ion batteries; Low temperature;

    Abstract : Lithium ion batteries (LIBs) are crucial for modern electronics and electric vehicles (EV). However,their electrochemical performance is facing challenges at low temperatures (e.g ≤ 0 °C) due to reducedLi+ kinetics and increased charge-transfer resistance. READ MORE

  4. 3. Multifunctional ice and snow repellent coatings for photovoltaic modules

    University essay from Uppsala universitet/Solcellsteknik

    Author : Gunnar Sandkvist; [2023]
    Keywords : sol-gel; superhydrophobic; dip-coating; anti-reflective; silica;

    Abstract : Implementation of solar power by photovoltaic modules in cold climates, such as northern Sweden, implies several challenges. Ice and snow coverage not only leads to reduction in energy production due to shading, but it also puts equipment at risk from additional weight. READ MORE

  5. 4. Linking the selectivity of varying surface phases of a real palladium catalyst toward specific methane oxidation pathways with Ambient Pressure X-ray Photoelectron Spectroscopy

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

    Author : Ulrike Küst; [2023]
    Keywords : APXPS; catalysis; palladium; methane; Physics and Astronomy;

    Abstract : The study of heterogeneous catalysis, especially within methane oxidation, is of high importance in order to more efficiently remove unburned methane from bio-fuel exhausts. This is relevant as bio-fuel engines will replace those driven by fossil fuels in the coming decades. READ MORE

  6. 5. Processing techniques of perovskite solar cells : Properties depending on material and manufacturing

    University essay from Uppsala universitet/Fysikalisk kemi

    Author : Andréa Nordmark; Simon Nilsson; [2023]
    Keywords : ;

    Abstract : This project investigates how different types of perovskite solar cells, differentiated by choice of materials and processing techniques, compares to each other regarding performance and characterization. The purpose of the project is to further develop perovskite solar cells and to improve the method of manufacturing for better performance. READ MORE
