Effect of aluminum content on dislocation loops in model FeCrAl alloys

Nuclear Materials and Energy, 2019
Five kinds of iron-chromium-aluminum (FeCrAl) alloy samples with different contents of aluminum (Al)—Fe-12Cr, Fe-12Cr-2Al, Fe-12Cr-4Al, Fe-12Cr-6Al, and Fe-12Cr-8Al—were designed and prepared. All samples were then irradiated with 200 keV argon ions (Ar2+

The Role of Open Cell Foams Supports on the Kinetics of PdO/Co3O4 for the Wet and Dry Lean Methane Combustion

ChemCatChem, Volume 18, Issue 5, 13 March 2026.
Kinetic analysis performed on FeCrAl, SiC and alumina open‐cell foams, washcoated with PdO/Co3O4 for the lean CH4 combustion in wet & dry environments. All structures demonstrated comparable catalytic activity and excellent H2O stability over time. The activation energies were 117 and 129 kJ mol−1 in dry & wet conditions.

Probabilistic Failure Analysis of SiC‐CMC/Nb Fuel Claddings Under Loss‐Of‐Coolant Accident Conditions

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
A numerical framework leveraging finite element analysis is established to examine the thermomechanical behavior and burst safety of a novel accident‐tolerant fuel (ATF) cladding design. This design incorporates a thin niobium (Nb) liner positioned between two layers of silicon carbide ceramic matrix composites (SiC‐CMC).

Scalable Exsolution‐Derived E‐Ni/m‐MgAlOx Catalysts with Anti‐Sintering Stability for Methane Dry Reforming

Small, Volume 21, Issue 43, October 29, 2025.
A sintering‐resistant E‐Ni/m‐MgAlOx catalyst with exsolved Ni nanoparticles shows >1000 h stability in methane dry reforming, achieving cumulative greenhouse gas conversion above 20000 L·gcat−1 at 800 °C–900 °C. Abstract Sintering and carbon deposition are primary causes of deactivation in Ni‐based catalysts during methane dry reforming (MDR).
