Summary: This study focuses on the micro-burnup (BU) studies of the uranium-zirconium (U-Zr) fuel system, where the microstructure undergoes a transformation from as-fabricated to starting microstructure in the reactor. Two U-Zr specimens were irradiated and the results show that the U-22.5 at.% Zr specimen retained its bulk features, while the U-52.8 at.% Zr alloy transformed into an equiaxed granular microstructure immediately upon reactor insertion. The study also discovers a face-centered-cubic Zr rind on the surface of the sample, indicating a possible diffusion-based process for the Zr-rind decomposition.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
