Gongye shui chuli, 2020 将阴离子交换树脂与电渗析进行耦合，构建了树脂耦合电渗析装置。结果表明：树脂耦合电渗析装置可有效去除N-甲基二乙醇胺（MDEA）吸附液中的热稳定盐（HSS）。该装置最佳操作条件：NaOH溶液质量分数3%，电压为30 V，淡化室厚度为2.5 mm。树脂耦合电渗析对MDEA吸附液中热稳定盐的去除率可达93.84%，远优于电渗析的65.27%；MDEA损耗率降低到3.78%，低于电渗析的MDEA损耗率（21.07%）。

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Nickel‐based materials are highly remarkable as promising transition metal catalysts for the electrochemical hydrogen evolution reaction (HER) in alkaline electrolytes. However, their electrochemical performance is limited by an unfavorable d‐band energy (Ed) level. Herein, we showcase an effective lattice‐strain strategy to modulate the Ed of

Gongye shui chuli, 2020 热力发电机组凝结水是锅炉给水的重要部分。但凝结水的复杂性决定了其发生污染的几率要远大于给水、蒸汽等。凝结水发生污染后会引起机组热力设备结垢、腐蚀、积盐，原因也较复杂。对凝结水污染原因进行分析，建立了凝结水污染诊断模型，用该模型并结合数据库中存储的凝结水数据可以确定污染因子。通过实例验证了污染模型可快速准确查找污染因子，保证机组水汽品质合格，从而达到机组安全稳定运行的目的。

Novel Non‐Equimolar High‐Entropy Zirconates With Superior Thermophysical Properties
Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Rare‐earth zirconates (RE2Zr2O7) are promising candidates for topcoat materials in thermal barrier coatings (TBCs). However, their practical application in TBCs is limited by poor fracture toughness and low thermal expansion coefficient (TEC).
