Enhancing the Ionic Conduction of Ceria‐Based Electrolytes for LT‐SOFCs via Entropy Engineering
Rare Metals, EarlyView.ABSTRACT Developing alternative electrolytes with enhanced ionic conductivity is crucial to reducing the operating temperature of solid oxide fuel cells (SOFCs) for broader applications. Entropy engineering offers many opportunities for material design, presenting a promising avenue to develop new electrolytes.

Small, EarlyView.A novel Pr‐based nanocomposite cathode consisting of PrNi0.7Co0.3O3‐δ (simple perovskite) and Pr4Ni3O10+δ (Ruddlesden‐Popper) demonstrates enhanced oxygen absorption/surface diffusion and oxygen reduction reaction activity than pure PrNi0.7Co0.3O3‐δ. Combined with the precursor‐based cathode layer deposition technique, the nanocomposite cathode also ...

steel research international, EarlyView.This review investigates the processing‐microstructure‐property relationships in ferritic stainless steels (FSSs). It highlights advances in deformation behavior, heat treatments, surface modifications, and alloying effects. Theoretical models, including Johnson‐Mehl‐Avrami‐Kolmogorov, Arrhenius, nucleation theory, and diffusion theories, are discussed
