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.

Advanced Materials, Volume 38, Issue 1, 2 January 2026.This study reveals an atomic‐level correlation between bulk dislocations and the exsolution of surface nanoparticles through a novel approach for dislocation engineering in epitaxial thin films. Employing in situ scanning transmission electron microscopy, two primary reasons for the frequent nucleation of dislocation‐associated nanoparticles are ...

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.

Redox‐Active Oxide/molten Salt Composites for Hybrid Thermal‐Chemical Energy Storage
Advanced Energy and Sustainability Research, Volume 7, Issue 1, January 2026.Redox‐active oxide–molten salt composites integrate sensible, latent, and thermochemical energy storage within a single particle. A porous Ca2AlMnO5+δ matrix infiltrated with eutectic NaCl/CaCl2 achieves a high‐energy density (267 kJ kg−1) over a narrow, 150 °C temperature window, offering a promising solution for high‐temperature thermal energy ...
