1. Material Supply Risks for the Energy Transition: A Quantitative Analysis of Resources, Production Concentration and Geopolitical Risks
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The Paris Agreement aims to limit the global temperature to below 2°C above the pre-industrial level. In order to achieve this target, almost 200 countries committed to Nationally Determined Contributions to reduce their greenhouse gas emissions. Diverse strategies are applied to achieve the necessary emissions reductions. LÄS MER
2. A Fabry–Pérot Cavity for Rare-Earth-Ion-Doped Nanocrystals
Kandidat-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenSammanfattning : This thesis work contributes to the effort of detecting single rare earth ions doped into crystals, an operation crucial for the development of rare earth quantum computer hardware. Doping crystals with rare earth elements, their trivalent ions substitute some of the crystal’s original bonds. LÄS MER
3. Single Ion Detection of Cerium in Y2SiO5 Microcrystals
Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenSammanfattning : Quantum computing with single instances of rare earth-ions doped into inorganic crystals shows great promise as a scalable design in the field of quantum information. A detectable and controllable single readout ion is necessary for the scheme proposed in Lund to work. LÄS MER
4. Rare-Earth Elements in the Swedish Alum Shale Formation: A Study of Apatites in Fetsjön, Västerbotten
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The Caledonian alum shales of Sweden host a vast number of economically interesting metals. In Fetsjön, Västerbotten, the shales contain significant amounts of rare-earth elements, vanadium, molybdenum and uranium. LÄS MER
5. Minerals and Magic Machines: A critical approach to modern agricultural technology and its connection to world-system flows of rare earth elements
Master-uppsats, Lunds universitet/HumanekologiSammanfattning : This thesis connects agricultural technology (ag-tech) within a Danish context to a world system of production in which rare earth elements (REs) play a crucial role. These elements are essential for modern technology. LÄS MER
