Oxide dispersion strengthened (ODS) steels are main candidates for structural applications in future fusion reactors. Understanding their irradiation induced behaviour is key to building optimized components with enhanced radiation resistance. In this work, the stability of an ODS Fe12Cr steel was investigated by transmission electron microscopy after single (Fe 4+) and simultaneous triple ion-beam irradiation (Fe 8+ , He + and H +) at room temperature to doses of 4.4 and 10 dpa. The irradiations were accomplished at the JANNUS-Saclay facility. Results after single ion-beam irradiation were also compared with those from a reference Fe12Cr steel produced following the same route. Analyses focused on determining the irradiation-induced loop size and density in the ODS and reference materials, investigating the grain boundary microchemistry and studying the evolution of the secondary phases present. These experiments show that the Y-rich nanoparticles present in the ODS steel are quite stable under these irradiation conditions although evolution of larger Cr-rich carbides could be taking place. Loop sizes are smaller for the ODS steel than for the reference material and appear to increase with dose. Cr segregates at some of the grain boundaries, though this segregation also occurs in the absence of irradiation.

“…As reported in our previous paper, the bright diffraction spots in the reciprocal space are contributed by the heavy atoms M 2+ and X – in perovskite materials (Pd 2+ and I – in this work), while the weaker diffraction spots originated from the light atoms of molecules CH 3 NH 3 + .

The feasibility of Pd-based organic−inorganic hybrid perovskites is comprehensively explored with both theoretical and experimental methods for the first time. Experimentally, the new 3D perovskite CH 3 NH 3 PdI 3 (tetragonal, I4cm) can be transited to a new 2D perovskite (CH 3 NH 3 ) 3 Pd 2 I 7 (tetragonal, P4mm) by modulating the ratio of the organic part to inorganic part. The structure, lattice parameters, and symmetry of these two perovskites are verified by a series of simulations, refinement, and characterizations. The basic optical and electronic properties of these two new perovskites are characterized and calculated with DFT for future applications. Interestingly, both types of perovskites exhibit long stability in air with 50% relative humidity. Two-day stability for the 3D perovskite and one-week stability for the 2D perovskite are observed, consistent with our DFT calculation that 2D perovskite (CH 3 NH 3 ) 3 Pd 2 I 7 is more energetically stable than 3D hybrid perovskite CH 3 NH 3 PdI 3 .
