Functional Ecology, Volume 40, Issue 5, Page 1428-1442, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract The stoichiometric imbalance caused by nitrogen (N) deposition typically exacerbates phosphorus (P) limitation in plants. However, it remains unclear whether this effect extends to soil microbes, particularly those in the rhizosphere.

Shuitu Baochi Xuebao, 2011 对大宝山矿区自然定居和人工种植的13种优势植物根际土壤污染状况及其对重金属的富集特征进行研究。结果表明,大宝山矿区土壤受重金属Cd、Pb、Zn、Cu污染,其中以Cd、Cu的污染最为严重。在调查的13种优势植物中,铺地黍地上部分的Pb含量达到1 214.00mg/kg,泡桐叶中Cu含量达到1 024.80mg/kg,超过了Pb和Cu超富集植物含量的临界值(1 000mg/kg);其运转系数分别为1.77,13.74,都大于1.0,符合超富集植物的标准,表明铺地黍可能是Pb的超富集植物 ...

High‐Value Targeted Conversion of Copper Slag as LiFePO4 Material for Lithium‐Ion Batteries
Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT The massive stockpiling of copper slag (CS) presents severe environmental and resource‐waste challenges. Existing strategies for CS valorization typically yield low‐value‐added products. Herein, we propose an innovative hierarchical regulation approach to transform CS into high‐performance LiFePO4 (LFP) cathode materials.

, 2008 本发明公开了一种微型质谱中样品直接进样在线富集的膜进样装置，采用无孔致密聚二甲基硅氧烷片状膜，能够有效限制进入质谱的气体量，同时可以做为质谱和大气的中间接口。装置中采用了单层超薄膜对样品进行快速富集，膜后具有一真空差分腔体，该腔体用来进行富集样品的缓冲和存储。该腔体处于低真空条件下，所以允许加大膜的面积，从而加大样品与膜的接触面积，富集效率提高。差分口处安装有电磁阀，当要进行气体富集时关闭抽气口，气体经过膜进入缓冲腔体进行富集。样品分析完毕后开通电磁阀门进行差分抽气，把富集后的样品迅速抽出防止记忆效应 ...

, 2011 本发明公开了一种利用金属氧化物富集糖肽以及同时富集糖肽和磷酸化肽的方法。本方法特点在于利用金属氧化物做为固相萃取材料，从蛋白酶解液中分离富集糖肽，并且利用简单的操作可以从一份样品中实现磷酸化肽和糖肽的同时富集。具体地说是在中性或弱酸性条件下将金属氧化物和样品混合，酸性条件洗脱得到糖肽，碱性条件洗脱得到磷酸化肽，可以在同一份样品中实现磷酸化肽和糖肽的高效率、高选择性的富集 ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Formic acid (FA) is considered to be a safe and convenient hydrogen source; however, achieving controlled and efficient FA dehydrogenation under mild conditions using stable solid catalysts remains a significant challenge. Pd‐based catalysts have been extensively studied due to their superior catalytic activity to other metal catalysts.

Shuitu Baochi Xuebao, 2008 通过盆栽实验,以小白菜(上海青)、大白菜和萝卜为指示作物,研究了酸雨作用下Cu,Zn,Pb,Cd,Cr和Ni复合污染物在土壤-作物系统中的吸收与富集情况。结果表明,酸雨-重金属复合污染处理使Cu,Pb,Cr和Ni在蔬菜中积累量明显高于对照处理;Zn和Cd一般只有在复合污染处理中外源Zn或Cd含量较高时才明显高于对照处理。与对照相比,酸雨-重金属复合污染处理使Pb和Ni的富集系数增大,Cu的富集系数多数情况下增大,Cd的富集系数多数情况下减小,Zn和Cr富集系数的变化在不同蔬菜之间存在较明显的差异 ...
