   University essay from Umeå universitet/Institutionen för fysik

   Author : Jonas Tejbo; [2023]
   Keywords : catalyst; metal-oxide; electrolysis;

   Abstract : Finding materials based on non-rare earth metals is vital for the global transition to a more sustainable economy. Discovering useful properties in common metal oxides is a promising avenue for new materials. READ MORE

3. 2. Investigating potential proton conductors: Doping BaTiO3 and SrTiO3 with Fe and Al

   University essay from Uppsala universitet/Strukturkemi

   Author : Julia Löfstrand; [2020]
   Keywords : Proton conductor; perovskite; solid state synthesis;

   Abstract : There are many interesting applications of proton conducting oxides, such as electrolytes in fuel cells, hydrogen sensors and catalytic membranes for hydrogenation or dehydrogenation of organic compounds. Previous work explored doping BaTiO3 with the Rare Earth Element (REE) Sc to introduce oxygen vacancies in the structure, making it a Proton Conductor (PC). READ MORE

4. 3. Characterization of an REE-enriched black substance in fractured bedrock in the Ytterby Mine

   University essay from Stockholms universitet/Institutionen för geologiska vetenskaper

   Author : Susanne Sjöberg; [2014]
   Keywords : ;

   Abstract : A black substance seeping from fractured bedrock was observed in tunnels leading to the mainshaft of the Ytterby mine on Resarö, Sweden. These are dry tunnels at shallow depth, +5 mabove sea level and 29 m below ground surface, resulting from the reconstruction of the mineinto a fuel deposit for the Swedish Armed Forces during the Cold War era.
