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/SynkrotronljusfysikSammanfattning : 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
2. Tuning electrolyte-electrode interphases for low-temperature Li-ion batteries
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/StrukturkemiSammanfattning : 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. LÄS MER
3. Multifunctional ice and snow repellent coatings for photovoltaic modules
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/SolcellsteknikSammanfattning : 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. LÄS MER
