Preparation of Ni–YSZ thin and thick films on metallic interconnects as cell supports. Applications as anode for SOFC [PDF]
, 2008 In this work, we propose the preparation of a duplex anodic layer composed of both a thin (100 nm) and a thick film (10 lm) with Ni–YSZ material. The support of this anode is a metallic substrate, which is the interconnect of the SOFC unit cell.

Chemical characterization of BiFeO3 obtained by Pechini method [PDF]
Journal of the Brazilian Chemical Society, 2008 This work describes the synthesis and characterization of BiFeO3 obtained by the Pechini route using bismuth nitrate and iron nitrate as precursors. The powders were annealed at 800 °C in air for 2 h. X-ray diffraction patterns showed that the material presents two phases, BiFeO3 (95%) and α-Bi2O3 (5%). The ferroelectric transition of the sample at 821

ZrTiO4 Nanowire Growth Using Membrane-assisted Pechini Route
Orbital - The Electronic Journal of Chemistry, 2016 The high surface-to-volume ratio of nanowires makes them natural competitors as newer device components. In this regard, a current major challenge is to produce quasi-one-dimensional nanostructures composed of well-established oxide-based materials.
