Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Developing oxygen evolution reaction (OER) catalysts that combine high performance with cost‐effectiveness is a critical challenge for advancing the commercialization of anion exchange membrane water electrolysis (AEMWE). Practical application is often hindered by issues such as poor batch reproducibility and low‐cost efficiency.

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Metal oxide‐based catalysts for oxygen reduction reaction (ORR) have drawn great attention in recent years. However, it remains technically challenging for the precise regulation of the overall performance due to the trade‐off effect among the activity, selectivity, and stability of electrocatalysts. Herein, a balancing strategy to control the

Zhongguo shiyan zhenduanxue, 2015 人体的正常温度总是维持在37℃,上下波动幅度不会超过1℃,这主要是通过神经调节来实现的。体温的升高或降低,都会影响到人体内正常的生理过程,进而发生代谢紊乱[1]。患者在接受手术的过程中,往往因为麻醉药的作用而无法正常调节体温,加之大量输液,手术室温度较低,使之在术中出现低体温现象。有报道称,50%以上的患者,在术中都会出现低体温现象。低体温会造成患者苏醒时间延长、凝血功能受损 ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Driven by global energy transition and sustainability, sodium‐ion batteries (SIBs) have emerged as key alternatives to lithium‐ion batteries for low‐to‐medium energy storage, because of abundant sodium resources and low cost. However, their commercialization is hindered by the lack of anodes with high capacity, fast kinetics, and long‐term ...

Zhongguo shiyan zhenduanxue, 2009 目的研究亚低温状态下,大鼠急性脑缺血时氧自由基—超氧化物歧化酶（SOD）和一氧化氮（NO）、一氧化氮合酶（NOS）的改变,探讨亚低温对缺血脑组织的保护机制。方法将45只Wistar大鼠随机分为9组,假手术组5只,缺血组及亚低温组又根据缺血、亚低温时间不同分为:3 h2、4 h4、8 h7、2 h亚组（各组均为5只）。采用颈内动脉线栓法制备大鼠大脑中动脉闭塞（MCAO）模型。结果比较缺血组和亚低温组,可见亚低温组栓塞侧脑组织超氧化物歧化酶（SOD）的生成和释放明显增加;亚低温组血清中一氧化氮（NO ...

Comparative proteomic analysis reveals cold acclimation enhances the cold tolerance in mangrove plant Sonneratia apetala [PDF]
, 2016 低温是一种重要的非生物胁迫因子，对植物的产量、分布具有重要的影响，特别是对生长、发育起着至关重要的作用。无瓣海桑(Sonneratiaapetala)是一种重要的红树植物，自1985年从孟加拉国引入中国后，以其生长迅速、树体高大、结实率高、在抵御护花米草入侵中发挥重要作用等特点迅速成为红树林湿地生态恢复中的理想树种。但无瓣海桑对低温较敏感，不耐寒，因此温度成为其生长和分布的重要限制因子之一。本论文研究经低温驯化和未经低温驯化无瓣海桑响应寒害的生理变化以及差异表达蛋白特性，阐明无瓣海桑的可能耐寒机理 ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT The high operating temperatures and sluggish kinetics of Mg‐based hydrogen storage materials (HSMs) are urgently being addressed. In this work, a novel Mg–Ni–Ga HSM with dual‐phase synergistic catalysis is developed, including the fishbone‐like Mg3Ni2Ga1 catalytic phase and the Mg2Ni phase with stacking faults (SFs).
