1. PGE Geochemistry and Mineralogy of Dunite, Chromitite, and Laterite Samples from the Acoje Ophiolite Block, Philippines
Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknikSammanfattning : Ni-laterites have the potential to become unconventional ore deposits for platinum group elements (PGE). This study was conducted to determine enrichment trends of PGE as a result of the Ni-laterization process. LÄS MER
2. A Simulation-Based Decision Support Tool for Circularity : Remanufacturing of an Electric Machine Case Study
Master-uppsats, KTH/ProduktionsutvecklingSammanfattning : Over the last years, environmental concerns have grown regarding the pressure manufacturing activities exerts on natural resources. Many materials have been classified by the EU as scarce, rare earth elements found in magnets are amongst critical materials with high supply risk. LÄS MER
3. The Promise of a Green Revolution : Conceptions of climate change and sustainability in local movements objecting to mining establishment
Master-uppsats, Uppsala universitet/Institutionen för kulturantropologi och etnologiSammanfattning : This study explores how vernacular understandings of climate change and sustainability are formed in relation to local disputes concerning mineral exploration. In a search for a solution to climate change, the interest in rare earth elements (REEs), and other metals used in green technology has resulted in granting mining companies processing concessions in Sweden.

4. A numerical comparison of the thermoacoustics for different equivalence ratios for n-dodecane using LES
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : Klimatförändringarna påverkar vår värld och det behövs ett mer hållbart samhälle. Flygindustrin är i behov av förändring, men flygmotorer är mycket komplexa och tar tid att utveckla. Termoakustiska instabiliteter har kraften att förstöra en motor, men också att minska miljöpåverkan. LÄS MER
5. Rare Earth Metals' Resiliency and Volatility Spillover Effects : A Critical Supply Assessment for Western Technologies From a Risk Management Perspective
Master-uppsats, Linköpings universitet/Nationalekonomi; Linköpings universitet/Filosofiska fakultetenSammanfattning : This paper explores the relationship between Chinese rare earth metals (REMs) and the industries in the U.S and Europe that heavily rely on them. LÄS MER
