Surface micromachining via solid electrochemical reaction on oxide ion conductors [PDF]

open access: yes, 2009
We propose a simple and novel route for the surface microstructuring of tough materials (glassy carbon, SiC, W and Mo) through a solid electrochemical reaction at a microcontact between the oxide ion conductor and target substrate. More specifically, the

Effects on Microstructure and Ionic Conductivity of the Co-Doping with Strontium and Samarium of Ceria with Constant Oxygen Vacancy Concentration

open access: yesSolids, 2021
Partially substituted cerias are attractive materials for use as electrolytes in intermediate-temperature solid oxide fuel cells (SOFCs). Ceria doped with Sm or Gd has been found to have high ionic conductivities.
