Nanocubes and Cuboctahedra: Entropic Stabilization Versus Thermal Segregation in Rock Salt‐ and Spinel‐Type Multinary Oxides from Spray‐Flame Synthesis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Spray‐flame synthesis enables highly flexible and scalable production of multinary and high‐entropy oxide nanoparticles due to high synthesis temperatures with subsequent quenching. Temperature‐dependent in situ diffraction of as‐synthesized materials clearly reveals entropy stabilization in rock salt lattices, while spinels—featuring tetrahedral and ...

NiO Dissolution in Molten Carbonate Fuel Cell Cathodes: Challenges and Strategies for Long‐Term Stability

ChemElectroChem, Volume 13, Issue 13, 2 July 2026.
Molten carbonate fuel cells (MCFCs) enable efficient power generation and CO2 capture but suffer from nickel oxide (NiO) cathode dissolution, which limits lifetime. This review summarizes strategies to mitigate NiO degradation, including coatings, doping, alternative cathode materials, and electrolyte modification.
