Dimensional Assembly Engineering of Ce‐MOF Interfaces for Selective Recognition of Phytic Acid
Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Selective molecular recognition is central to chemical sensing yet discriminating structurally similar molecules at complex interfaces remains challenging. Traditional strategies based on tuning size, charge, or binding‐site chemistry often suffer from limited flexibility.

Integrative Conservation, Volume 5, Issue 1, Page 86-103, March 2026.Urbanization may alter bird foraging. Austral Parakeets (Enicognathus ferrugineus) in Patagonia rely on introduced plants in urban areas, especially in winter, despite preferring natives in the wild. This seasonal reliance on introduced species highlights urbanization trade‐offs and underscores the need to manage green areas with native plants to ...

Integrative Conservation, Volume 5, Issue 1, Page 125-136, March 2026.We collated detections of the sun bear from new and previously published camera trap studies across its range. We then analysed these detections at two different spatial scales to assess the habitat associations and diel activity of this species. We found that the sun bear is tolerant to moderate habitat disturbances. ABSTRACT Degraded tropical forests,

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 ...

, 2017 通过气体交换、荧光诱导动力学和荧光淬灭动力学等技术探讨了种植密度对薄荷光合特性及光系统Ⅱ(PSⅡ)功能的影响。结果显示:增加种植密度会显著降低单株的总叶面积、叶绿素含量和光饱和光合速率,但对叶片的表观量子效率(AQY)影响较小。随着种植密度的升高,叶片的快速叶绿素荧光诱导动力学曲线(OJIP)明显改变,但最大光化学效率(φ_(Po))变化不大;进一步分析表明,叶片单位截面有活性反应中心的数量(RC/CS_0)和单位面积吸收(ABS/CS_0)、捕获(TR_0/CS_0)及用于电子传递的能量(ET_0 ...

Shuitu Baochi Xuebao, 2017 以黄土丘陵区4种典型植物种群（狼牙刺、白羊草、铁杆蒿、达乌里胡枝子）为研究对象，采用野外采样、室内模拟试验与分析相结合的方法，对0—30 cm土层的各径级根系密度参数（根长密度、根体积密度、根表面积密度）与土壤理化性质、土壤分离速率间的关系进行了研究。结果表明：（1）4种植物的根系径级主要集中在0＜D≤1.0 mm之间，86%～93%的根长和46%～61%的根系表面积分布在此范围内，且根系径级越大，根系各密度参数越小；（2）4种植物各径级根密度参数对土壤理化性质（容重、有机质、团聚体）的影响各不相同 ...
