      abstract     = {Advanced concepts for oxygen transport membranes focus on
                      thin layers supported by a porous substrate. To warrant long
                      term reliable operation of such systems, an assessment of
                      the mechanical stability of each membrane component is
                      required. With respect to chemical stability, cerium oxide
                      and doped cerium oxides are promising materials for this
                      application. The present work addresses the mechanical
                      properties of cerium oxide variants, aiming to elucidate
                      properties of relevance to the manufacture of reliable
                      cerium oxide components. In particular
                      Ce0.8Gd0.2−yPryO2−δ membrane materials and the
                      influence of an addition 2 $mol\%$ of CoO is assessed.
                      Materials preparation and compositional variations are
                      compared with respect to elastic modulus, hardness and
                      fracture toughness, as characterized using depth sensitive
                      indentation. Furthermore, the creep behavior of doped and
                      undoped cerium oxides, that is important for the long term
                      structural stability at temperatures relevant to the
                      oxygen-membranes operation, is assessed and critically
                      discussed.},
