1. 1. 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

3. 2. Effect of iron redox state on crystallization behaviour of Fayalite slags

   University essay from KTH/Materialvetenskap

   Author : Paolo Mai; [2020]
   Keywords : Copper smelting; Slag; Magnesium Oxide; Iron redox equilibria; Optical basicity; Raman spectroscopy.; Smältning av koppar; Slagg; Magnesiumoxid; Järnredoxjämvikt; Optisk basicitet; Ramanspektroskopi.;

   Abstract : In the copper smelting processes, the viscosity of the matte and the slag is an important factor for establishing efficiency. Impurities in the concentrates affect the viscosity not only by changing the melt structure but also by promoting precipitation of solid phase which sharply rises it. READ MORE

4. 3. Modelling Mössbauer spectra of biotite

   University essay from Lunds universitet/Geologiska institutionen

   Author : Jonas Bermin; [2001]
   Keywords : spectroscopy; geology; biotite; Mössbauer; geography; Earth and Environmental Sciences;

   Abstract : Mössbauer-effekten används i detta arbete för att bestämma oxidationsgrad och plats besättning i biotiter som har blivit behandlade vid olika pH. Arbetet ger också en introduktion till teorin bakom Mössbauereffekten samt till Mössbauer-spektroskopi. READ MORE
