Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Graphitic carbon nitride (g‐C3N4) doped with 3d transition metals (3d‐TM@g‐C3N4) has gained attention as a noble metal‐free alternative for oxygen evolution and reduction reactions (OER/ORR). Yet the key mechanisms driving its performance remain debated, especially across different charge states.

A Multifunctional Reducing Molecular Dopant for 16% Efficient Tin Perovskite Solar Cells
Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Although lead‐based photovoltaics have seen remarkable progress, tin‐based perovskite solar cells (Sn‐PSCs) continue to face challenges due to their limited power conversion efficiency and insufficient operational stability. The primary cause of this performance gap is the susceptibility of Sn2+ to oxidation, which promotes rapid defect ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Intervertebral disc degeneration (IDD) is a predominant cause of low back pain, significantly impacting quality of life. Mitochondrial fitness is essential in the progression of IDD, as it regulates cellular senescence and pyroptosis. This study investigates the role of mitochondrial caseinolytic protease P (ClpP) in alleviating senescence and

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Silicon oxide (SiO) is becoming the main anode for high‐energy lithium‐ion batteries because of its ease of manufacture, outstanding cycling stability, and high capacity. However, low initial Coulombic efficiency (ICE) caused by the irreversible reaction of silica, as the main issue, strictly limits its commercial applications.

Gongye shui chuli, 2021 采用“空气吹脱-硅藻土过滤-Fenton氧化”组合工艺对环氧树脂废水进行深度处理，重点考察预处理方式、不同氧化剂及其工艺条件对废水TOC去除效果的影响。结果表明：废水（TOC 3 000~4 000 mg/L）经预处理后，Fenton氧化工艺优选条件为：初始pH为4左右，双氧水1 200~1 300 mmol/L，Fe2+ 12 mmol/L，双氧水和亚铁试剂采用分次滴加法。在此条件下，废水TOC去除率在98%以上，TOC稳定在100 mg/L左右，可作为生产氯气和烧碱的原料，实现了废水资源化利用。

Gongye shui chuli, 2014 采用次氯酸钠、臭氧及芬顿试剂化学氧化法对焦化废水进行预处理，考察了3种药剂对焦化废水CODCr、氨氮的去除效果及废水可生化性的提高。结果表明，次氯酸钠氧化处理对焦化废水中氨氮的去除率较高，但对废水可生化性的提高不大；臭氧氧化处理对焦化废水中CODCr和氨氮的去除率均较低，但对废水的可生化性提高迅速，反应3 min后废水的可生化性即可由0.068提升到0.281；采用芬顿试剂氧化处理，在较佳条件下，废水的可生化性可达到0.445，但运行成本高。综合考虑，采用臭氧氧化预处理焦化废水更具优势。
