Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Integrating light emission and electromagnetic wave (EMW) absorption into a single material opens up possibilities for multienvironmental applications. Herein, we propose a novel “molecular engineering‐pyrolysis conversion” strategy to construct a bifunctional system with tunable photoluminescence and efficient EMW absorption performance.

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 ...

Huli yanjiu, 1988 静脉输液在临床上应用极为广泛,已成为抢救中不可缺少的一项重要措施。在输液过程中,有时出现热原反应而影响治疗,甚至引起严重后果。因此,预防热原反应已引起广大医务人员的重视。一般认为在药房制剂、供应室处理输液器及临床输液操作每个环节中任何一个环节如果处理不当,均可引起热原反应,而其中输液器的处理尤为关键。这里谨就热原的特性及其与输液器处理的关系,提出处理输液器的方法,供同志们参考。
