      abstract     = {Asymmetric oxygen transport membranes have been extensively
                      studied revealing the importance of the support porosity. In
                      this study, asymmetric membranes with vertically channelled
                      pores were prepared from
                      Ba0.5Sr0.5(Co0.8Fe0.2)0.97Zr0.03O3-δ (BSCF-Z) by phase
                      inversion tape casting. The rate-limiting effects of the
                      membrane layer thickness, the support structure, and the
                      activation layers were thoroughly analysed. This entails
                      comparing the permeation rate of the samples with the
                      membrane layer on different sides of the channelled
                      supports. Pore tortuosity and computed permeability were
                      evaluated from 3D-X-ray computed tomography and compared to
                      previously reported asymmetric membranes prepared by
                      tape-casting and freeze-drying. Due to a lower pore
                      tortuosity, the channelled supports have an advantage in gas
                      transport over the tape cast and freeze cast supports.
                      However, this is compensated by a thicker membrane layer
                      (∼54 μm) resulting in similar performance compared to the
                      thinner membrane layers (∼20 μm) with freeze cast and
                      tape cast supports.},
