A-site deficient perovskite La0.57Sr0.15TiO 3 (LSTO) materials are synthesized by a modified polyacrylamide gel route. X-ray diffraction pattern of LSTO indicates an orthorhombic structure. The thermal expansion coefficient of LSTO is 10.0 × 10-6 K -1 at 600 °C in 5%H2/Ar. LSTO shows an electrical conductivity of 2 S cm-1 at 600 °C in 3%H2O/H 2. A new composite material, containing the porous LSTO backbone impregnated with small amounts of Ce0.9Gd0.1O 2-δ (CGO) (3.4-8.3 wt.%) and Ni/Cu (2.0-6.3 wt.%), is investigated as an alternative anode for solid oxide fuel cells (SOFCs). Because of the substantial electro-catalytic activity of the fine and well-dispersed Ni particles on the surface of the ceramic framework, the polarization resistance of 6.3%Ni-8.3%CGO-LSTO anode reaches 0.73 Ω cm2 at 800 °C in 3%H2O/H2. In order to further improve the anodic performance, corn starch and carbon black are used as pore-formers to optimize the microstructure of anodes. © 2014 Elsevier Masson SAS. All rights reserved.

The centrosymmetric title molecule, C28H32N 2O2, has a central benzene ring subsituted in the 1-and 4-positions by (ethene-2,1-diyl)pyridine groups, and in the 2-and 5-positions by butoxy groups. The whole molecule is X-shaped and relatively flat, the dihedral angle between the pyridine and the central benzene ring being 11.29 (10)°. In the crystal, neighboring molecules are linked by weak C-H⋯N inter-actions, forming a two-dimensional undulating network.
