Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT The development of efficient and stable bifunctional electrocatalysts is a key challenge for the industrialization of hydrogen production by water electrolysis. In this work, Co‐doped NiS/Ni3S2 heterostructured nanowire arrays (Co–NiS/Ni3S2 NA) were successfully constructed by precisely modulating the phase‐selective behavior of nickel ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Platinum (Pt)‐based catalysts are crucial for the commercialization of hydrogen/metal air batteries, but they suffer from Pt scarcity, high cost, and nanoparticle dissolution/agglomeration, mainly leading to performance degradation. We address this by synthesizing a PtFe alloy catalyst (PtFe–PA–NC) via a phytic acid (PA) assisted pyrolysis ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Tellurium (Te), emerging as a promising alternative to sulfur (S) and selenium (Se), offers significant advantages for potassium (K) ion storage due to its comparable theoretical volumetric capacity (2619 mAh cm−3) and higher electronic conductivity (∼102 S m−1), which promotes rapid charge transfer and improves reaction kinetics.

Wavelet coding based on predicted classification(一种基于预测分类的小波图像编码)
Zhejiang Daxue xuebao. Lixue ban, 2002 对于小波图像编码,如何有效地组织小波域系数是提高图像压缩效果的关键.本文在研究小波域系数统计特性的基础上,提出一种用于图像压缩的预测分类模式.与基于零树结构的编码不同的是它充分利用了小波域中"重要"系数的各种相关性,并通过结合提出的种子膨胀算法实现系数的分类输出.实验结果表明该方法所取得的压缩效果要优于基于零树结构的图像编码,同时又具有较强的鲁棒性.

Functional Ecology, Volume 40, Issue 3, Page 636-654, March 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract The nested subset pattern (nestedness) has been widely used to explain species distributions in island and fragmented systems. Mountain sky islands serve as critical natural laboratories for understanding the evolutionary consequences of geographic isolation and climate

Subsidies, Net Zero Transition and Public Debt: An Analysis for the Oil and Gas Industry in Brazil
Latin American Policy, Volume 17, Issue 1, March 2026.Abstract Despite awareness of the challenges in promoting the decarbonization of the economy, explicit fossil fuel subsidies have increased considerably worldwide in the past decade, reaching an all‐time high at US$1 trillion in 2022. Considering the net‐zero transition and the increase of modern public debt, this article assesses the most relevant ...

Zhejiang Daxue xuebao. Lixue ban, 2000 本文以依存语法作为语言模型的基础，首先提出了一种全新的句子分析策略：分析在两级上进行。一级是基于中心动词同其他成分间的约束关系，通过寻找汉语语义类之间可能存在的句法关系，实现句子成分过滤，完成句子主干提取。另一级是上下文级，将语法、语义和语境信息一体化，结合依存语法确定汉语句子中各成分间的依存关系。之后给出了一种快速有效的用于完成句子分析的松弛匹配迭代算法。通过实验表明了该分析策略和算法的可行性。
