Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Platinum (Pt) single‐atom catalyst (SAC) shows great promise for hydrogen evolution reaction (HER), but faces a huge challenge in activity enhancement due to the isolated single‐atom sites. Fabricating support with partially amorphous (pa) structures to realize the synergetic interaction in neighboring single atoms could facilitate H2O ...

Gaoya dianqi, 2022 环氧树脂由于其优异的绝缘密封性能被广泛应用于干式空心电抗器，然而在湿热环境中环氧树脂易吸水受潮导致材料性能劣化，严重影响设备的安全稳定运行，掌握材料的吸水与脱水行为对其实际应用具有重要意义，因此文中研究了环氧树脂在不同酸碱盐溶液中的吸水与脱水特性。实验结果表明：环氧树脂在不同溶液中的吸水过程符合菲克第二定律；吸水速率和饱和吸水率与两侧溶液浓度差有关，环氧树脂在去离子水中的吸水速率最大；脱水过程也是一种渗透作用，环氧树脂脱水速率很快，相对平衡脱水率几乎能达到100%。

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Layered double hydroxides (LDHs) are attractive non‐noble catalysts for overall water splitting (OWS), yet their hydrogen evolution reaction (HER) activity is often limited by suboptimal *H adsorption and a paucity of accessible sites. Herein, we introduce an oxygen‐vacancy (Ov) engineering strategy to construct ultrathin Ni‐Fe LDH nanosheets ...
