Entrapment Behavior of Solid Surrogate Fission Products at Engineered UN Nano‐Hetero‐Interfaces Within Metallic Nuclear Fuels

Advanced Materials Interfaces, Volume 12, Issue 22, November 22, 2025.
This work endeavors to engineer uranium mononitride (UN) nanostructures within a metallic nuclear fuel (U─Mo), in order to trap potential fission products (Nd). From consolidation of the nanostructured U─Mo powders all the way to 1000 h at reactor‐like temperatures (500 °C), Nd preferentially migrates to nanostructure boundaries (hetero‐interfaces ...

Tailoring strength and ionic conductivity in zirconia‐based solid oxide electrolytes using a multimaterial approach

Journal of the American Ceramic Society, Volume 108, Issue 11, November 2025.
Abstract A multimaterial approach is explored for tailoring the mechanical and functional properties of zirconia‐based ceramic electrolytes to be employed in electrochemical solid oxide cells (SOCs). The combination of alumina‐toughened zirconia (ATZ) surface layers with an embedded 8 mol% yttria‐stabilized zirconia (8YSZ) core layer introduces ...
