1. 1. Reduction of iron oxide by hydrogen studied using environmental transmission electron microscopy

   Master-uppsats, Lunds universitet/Centrum för analys och syntes

   Författare :David Wahlqvist; [2020]
   Nyckelord :Transmission Electron Microscopy; Electron Diffraction; Iron Oxide; Reduction; Iron; Environmental Transmission Electron Microscopy; ETEM; Materials chemistry; Materialkemi; Chemistry;

   Sammanfattning : This thesis aims to explore how the reduction of iron oxide by hydrogen should be explored in an environmental transmission electron microscope (ETEM). This is done by performing a series of reduction attempts in the ETEM at nCHREM, Lund University, and exploring how the ETEM conditions are different from those used commercially. LÄS MER
