1. 1. Material Supply Risks for the Energy Transition: A Quantitative Analysis of Resources, Production Concentration and Geopolitical Risks

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Ria Pozybill; [2022]
   Keywords : Sustainable development; Critical minerals; Geopolitical risks; Cobalt; Rare earths; Lithium;

   Abstract : 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. READ MORE

3. 2. A Fabry–Pérot Cavity for Rare-Earth-Ion-Doped Nanocrystals

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

   Author : Andre Nüsslein; [2019]
   Keywords : Quantum Computer; Rear Earth Ions; Cavity; Laser; Cavity Quantum Electrodynamics; QED; Solidworks; Physics and Astronomy;

   Abstract : 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. READ MORE

4. 3. Single Ion Detection of Cerium in Y2SiO5 Microcrystals

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

   Author : Vassily Kornienko; [2019]
   Keywords : cerium; YSO; rare-earths; quantum computing; microcrystals; Physics and Astronomy;

   Abstract : 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. READ MORE

5. 4. Rare-Earth Elements in the Swedish Alum Shale Formation: A Study of Apatites in Fetsjön, Västerbotten

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Fredrik Engström; [2019]
   Keywords : apatite; rare-earth elements; uranium; alum shales; caledonides; apatit; sällsynta jordartsmetaller; uran; alunskiffer; kaledoniderna;

   Abstract : 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. READ MORE

6. 5. Minerals and Magic Machines: A critical approach to modern agricultural technology and its connection to world-system flows of rare earth elements

   University essay from Lunds universitet/Humanekologi

   Author : Niklas Sjøbeck Jørgensen; [2018]
   Keywords : Technology; ag-tech; agriculture; Denmark; rare earths; extractivism; mining; China; discourse; reductionism; politics; nature; machines; fetishism; world system; supply chain; critical realism; Social Sciences;

   Abstract : 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. READ MORE
