1. 16. Computational Study of the Magnetocrystalline Anisotropy Energy of Ordered CoPt

   University essay from Uppsala universitet/Materialteori

   Author : Max Fusté Costa; [2022]
   Keywords : ;

   Abstract : The study of the properties of magnetic materials is of primary importance in the development of newtechnologies. In this project, we aim to investigate the symmetries of some of the relevant properties ofa cobalt and platinum alloy that emerge from the symmetry of the crystal structure of the alloy. READ MORE

3. 17. The Dark Side of Mineral Sourcing : The Responsible Sourcing Practices of Industrial Manufacturing Firms

   University essay from Karlstads universitet/Handelshögskolan (from 2013)

   Author : Ajnur Mujanovic; Erik Österberg; [2022]
   Keywords : Responsible sourcing; supply chain due diligence; supply chain visibility; traceability; supply chain management; Digital Twin; Etiskt inköp; supply chain due diligence; supply chain visibility; spårbarhet; supply chain management; Digital Twin;

   Abstract : In order to succeed with the Sustainable Development Goals, the mining of minerals will need to not only continue, but increase in the coming years. The extraction of minerals such as gold and cobalt is often associated with human rights violations and the financing of criminal enterprises. READ MORE

4. 18. Long-Term Impact of Drought on AcidSulfate Soil Leaching, a Study of NineCatchment Areas in Sweden and Finland

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Emilie Åström; [2022]
   Keywords : acid sulfate soil; hydrological drought; water chemistry; metal leaching; sulfate concentration; sur sulfatjord; hydrologisk torka; vattenkemi; metallurlakning; sulfatkoncentration;

   Abstract : Sediments rich in sulfide were deposited in the Littorina sea in an environment that was shallow, anoxic,and reductive. The sediments were brought above sea level by isostatic uplift and can now be foundalong the coast of the Baltic sea. READ MORE

5. 19. Investigating Brønsted Acidic Deep Eutectic Solvents for Recycling of Lithium Cobalt Oxide

   University essay from Uppsala universitet/Strukturkemi

   Author : Mattias Lindgren; [2022]
   Keywords : Deep eutectic solvents; Recycling; Lithium-Ion Batteries; Cathode Materials; LCO;

   Abstract : Recently, the production of lithium-ion batteries (LIB) has grown rapidly, highlighting the need for efficient and environmentally friendly recycling of LIB waste. In this work, the usage of so-called deep eutectic solvents (DESs) for the leaching of the LIB cathode material lithium cobaltoxide is investigated. READ MORE

6. 20. Demonstration and investigation of hydrogen production by water splitting through plasmon assisted photocatalysis involving a cobalt catalyst.

   University essay from Uppsala universitet/Fysikalisk kemi

   Author : Amal Mendalz; [2022]
   Keywords : ;

   Abstract : Plasmonic heterostructures are of great interest within the industry and in the academia owing to theirapplications in photovoltaics and photocatalysis. The Localised surface plasmon resonance (LSPR) leading to an intensification of the electromagnetic (EM) field on the surface of the plasmonic nanoparticles results in an efficient absorption of light over miniscule thickness of the material.
