Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Overcoming the strength–ductility trade‐off in face‐centered cubic (FCC) multi‐principal element alloys (MPEAs), particularly at cryogenic temperatures, remains a significant challenge. Here, a laser powder bed fusion (LPBF)–enabled direct aging strategy is employed to modify the precipitation behavior in a Ni53Fe20Cr23Nb4 (at%) alloy.

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Sodium‐ion batteries (SIBs) offer a promising, cost‐effective alternative for large‐scale energy storage due to the abundance of sodium. However, their practical deployment is challenged by sluggish interfacial kinetics and unstable interphase formation, which severely limit performance across wide temperature ranges. Here, we demonstrate that

VO2 Hollow Nano‐Reactor: Enabling Near‐Room‐Temperature and Ultrafast Hydrogen Release From α‐AlH3
Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT α‐phase aluminum trihydride (α‐AlH3) is a promising high‐capacity hydrogen storage material, but its practical application is limited by slow dehydrogenation kinetics and high reaction temperatures. This study demonstrates, for the first time, effective modulation of the hydrogen release kinetics of AlH3 by employing a hollow nanostructured ...

Gaoya dianqi, 2019 随着特高压交流工程建设的不断开展,越来越多特高压变电站将建设在低温地区。由于特高压开关设备普遍采用SF6气体绝缘,在低温地区使用会存在低温液化问题,降低设备运行稳定性,提升电网运行风险,需采取措施提高设备耐受低温能力。基于设备重要性的考虑,对于1 100 kV GIS,宜采用户内布置方式。对于户外使用的1 100 kV出线套管和分支母线可采用降低气压的方法降低气体液化温度。对于其他电压等级的GIS设备,可在设备外壳加装加热装置,按一定程序对设备气室加热,保证绝缘和灭弧介质SF6的状态稳定 ...
