Nanostructured Anodes for Solid Oxide Fuel Cells Obtained by Screen‐Printing and Infiltration

Fuel Cells, Volume 25, Issue 5, October 2025.
ABSTRACT Nanomaterials were used for the investigation of electrochemical performance tests of solid oxide fuel cells. Two different approaches were chosen to produce symmetrical nanoparticle (NP)‐based cells: screen printing and infiltration. Screen printing, as a state‐of‐the‐art manufacturing process, leads to unstable NiO/gadolinium‐doped ceria ...

Large-scale synthesis of YSZ nanopowder by Pechini method

Bulletin of Materials Science, 2014
Yttria-stabilized zirconia nanopowders were synthesized on a relatively large scale using Pechini method. In the present paper, nearly spherical yttria-stabilized zirconia nanopowders with tetragonal structure were synthesized by Pechini process from zirconium oxynitrate hexahydrate, yttrium nitrate, citric acid and ethylene glycol.

Femtosecond laser crystallization of YAG in yttrium aluminosilicate glasses

International Journal of Applied Glass Science, Volume 16, Issue 4, October 2025.
Abstract This work demonstrates the capability to crystallize YAG via femtosecond pulsed laser. Challenges in using melt‐quench glass are shown to restrict glass composition and have not yielded YAG via femtosecond laser crystallization. An alternative glass‐making technique was used to fabricate a range of compositions not otherwise possible.

PECHINI SYNTHESIS AND CHARACTERIZATION OF Eu3+ DOPED ZnCo2O4 SPINELS [PDF]

Periódico Tchê Química, 2005
Spinel oxides with the composition ZnCo2O4 and ZnCo2O4:Eu3+ have been synthesized by the Pechini method and characterized by X-ray diffraction, infrared spectroscopy, thermal analysis and scanning electron microscopy. IR spectroscopy revealed the presence of n1 and n2 bands, typical of spinel structures.

Characteristics of (Sr0.92Y0.08)0.85Ti1‒xNixO3‒𝛿 (x = 0.05, 0.10, 0.15, 0.20) perovskites for internal dry methane reforming in solid oxide fuel cells

Journal of the American Ceramic Society, Volume 108, Issue 10, October 2025.
Ni‐doped Sr0.92Y0.08TiO3 perovskite has been investigated to improve the catalytic activity for CO2 dry internal reforming of methane in SOFCs. A‐site‐deficient SYTN perovskites eluted 3‒5 nm sized Ni nanoparticles onto the surface. The non‐stoichiometric perovskite catalysts improved the CO2 dry reforming performance as well as enhancing ...

Synthesis of inter‐lanthanide sesquioxides LnLn'O3 by polymeric steric entrapment

Journal of the American Ceramic Society, Volume 108, Issue 10, October 2025.
Abstract Lanthanide oxides are well known in the fields of optical, electronic, and magnetic materials. Even so, there are many application spaces yet to be explored. Previous modeling of inter‐lanthanide sesquioxides, in which the compound contains two lanthanide cations, predicts the lowest level energy structure as a function of chemistry, which ...
