We have performed 
Si nuclear magnetic resonance (NMR) experiments using single crystal of strongly correlated 
electrons system URuSi under high external field of about 24 T. The temperature dependence of NMR shift in the paramagnetic state varies with external fields. The temperature and field dependences of NMR shifts resembles those of magnetic susceptibility.

In Fe-Cr-Al (ODS) alloys being developed as accident tolerant fuel cladding for light water reactors, it is a challenge to understand and predict the precipitation behaviour of the Cr-rich embrittlement phase (
phase), which occurs at relatively low irradiation temperatures, and its effect on mechanical properties. Therefore, in this study, the 
phase boundary was rationally defined on the alloy state diagram under varying conditions such as temperature and aging time by combining thermal aging experiments on Fe-Cr-Al alloys with systematically varying Cr and Al compositions and machine learning models. The regression model was applied to the 3DAP database to evaluate the relationship between the estimated increase in Vickers hardness and the hardening mechanism due to the phase. The results suggest that the hardening due to the phase can be explained by a particle cutting mechanism.
