“…The magnitude of the band gap directly determines the insulation performance and directly affects the breakdown field strength, which is a key indicator of energy-storage performance. Thus, the hv − (αhv) 2 (α and h are absorption coefficient and Planck constant, respectively) curves of 100xNT ceramics with different NT contents are obtained by measuring the UV-visible absorption spectra of ceramics. As presented in Figure 3, with increasing NT content, the band gap of ceramics increases first and then decreases.…”

Currently, the energy‐storage properties of dielectric ceramic capacitors have aroused wide attention; however, most materials exhibiting excellent energy‐storage properties are based on high electric fields, which increase the cost of insulation technology. Herein, the energy‐storage and charge–discharge properties of (1 − x)(0.7Bi0.65Na0.35Fe0.3Ti0.7O3–0.3Sr0.85Bi0.1TiO3)–xNaTaO3 (x = 0.03–0.18, abbreviated as 100xNT) ceramics are investigated. 9NT achieves superior energy‐storage properties under a low electric field of 210 kV/cm, with an energy‐storage density (Wrec) of 3.44 J/cm3 and efficiency (η) of 86.6%. The energy‐storage properties exhibit excellent frequency stability in 3–100 Hz as well as temperature stability between 25 and 175°C. Furthermore, the charge–discharge performance features a high‐power density (PD = 67.04 MW/cm3), and an ultrafast discharge speed (t0.9 = 52 ns). This work paves a new way to explore energy‐storage competitive materials under low electric fields.

A plate-type nuclear fuel consisting of a solid monolithic foil of U-10wt%Mo is under development for use in the United States' high performance research reactors. In support of developing this fuel, the fuel has been fabricated for the first time by a commercial fuel vendor and subsequently irradiated in a test reactor. This provides an opportunity to evaluate post-irradiation mechanical properties of the commercially fabricated fuel. Four-point bend testing was conducted on the irradiated U-10Mo samples to generate the fuel material properties, including the modulus of elasticity and the bending strength. Although the material behaves in a brittle manner due to the accumulated porosity, a general trend of strength and modulus reduction were found as fission density increases. The data produced was evaluated using both Weibull statistics and a modulus degradation model with recommendations provided.
