      abstract     = {Hierarchically porous SrTi0.75Fe0.25O3-δ specimens were
                      produced through a freeze drying procedure, which yielded a
                      channel-like porosity, reaching a value of $32\%.$
                      Compressive testing was used to determine apparent elastic
                      modulus and fracture stresses in the transverse
                      (out-of-plane) and longitudinal (in-plane) direction,
                      revealing a strong dependence onto pore orientation. The
                      lower mechanical stability in the in-plane direction appears
                      to be associated with bending mode of the pore walls, being
                      a result of a lower resistance to crack initiation. Acoustic
                      emissions recorded during compressive tests indicated
                      continuous damage of the pore walls before complete failure
                      of the specimen, which could be also confirmed by
                      complementary in-situ compressive tests in a scanning
                      electronic microscope.},
