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.

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Thermo‐responsive hydrogels based on poly(N‐isopropylacrylamide) (PNIPAM) are promising candidates for soft actuation, yet their practical applications are often constrained by sluggish thermo‐responsive kinetics and insufficient mechanical robustness.

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The development of high‐voltage aqueous zinc‐ion batteries (AZIBs) is primarily hindered by the lack of suitable cathode materials and electrolytes that can work in broad voltage windows. Herein, we propose a synergistic strategy that concurrently addresses these challenges through the integration of an amorphous vanadium oxyphosphate/graphene

Gongye shui chuli, 2014 对钢渣进行粉碎和烧结造粒，通过批次试验考察了其吸附除磷的特性。结果表明：钢渣陶粒的除磷效果显著，且对进水pH有较好的适应性。与颗粒内扩散模型相比，准二级动力学方程能更好地描述钢渣陶粒对磷的吸附全过程；钢渣陶粒对磷的等温吸附是以化学吸附为主的单层吸附，符合Langmuir模型，是自发、吸热的熵增型反应，升温有利于吸附的进行。

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.

Gongye shui chuli, 2014 研究了电子受体和碳源对活性污泥反硝化除磷的影响。亚硝酸盐和硝酸盐都可以作为电子受体在缺氧的条件下实现对磷的吸收，但其吸磷效率比氧低。较高的亚硝酸盐浓度会严重抑制污泥的活性，当一次加入NO2-质量浓度为46 mg/L时，反硝化吸收磷不能发生；而分4次加入（每次11.5 mg/L），吸磷量可达到19.5 mg/L。电子受体浓度为0.24 mmol/L时，吸收的P和加入的N的物质的量比：NO2-为1.7，NO3-为4.7。在低的碳源浓度下，碳源可以促进反硝化磷吸收；碳源浓度过高，系统形成厌氧环境，磷反而被释放。

Shuitu Baochi Xuebao, 2020 稻-麦轮作是太湖流域典型的集约化粮食作物种植体系，化肥用量大，氮磷流失控制广为关注。采用大区田间对比试验，研究了习惯施肥（FP）和优化控制施肥（CM）2种施肥模式对作物产量及氮磷肥料偏生产力的影响，同时探讨了2种施肥模式下农田径流水中各形态氮、磷的特征和径流氮、磷损失的差异。结果表明：优化控制施肥水稻和小麦地上部总生物量、籽粒产量、植株地上各部位养分（氮磷钾）含量及积累量与习惯施肥差异不显著（P>0.05）；优化控制施肥水稻和小麦的氮肥偏生产力显著大于习惯施肥 ...

Gongye shui chuli, 2015 采用低饱和共沉淀的方法合成了n(Fe):n(Mg):n(Al)=1:1:1的铁镁铝三元类水滑石。研究其对磷的吸附特性,考察了吸附时间、投加量、温度、pH等因素对吸附效果的影响。结果表明:此类水滑石对磷的吸附在前20 min吸附量急剧增加,40 min之后趋于稳定;当投加量为1.0 g/L时,吸附率和吸附容量都相对较高;初始pH为3～10时,对吸附效果无明显影响;温度对吸附效果影响较大,温度升高吸附量增加,表明此吸附过程是吸热过程。此类水滑石对磷的等温吸附数据与Langmuir方程的相关系数很高,45 ...

Gongye shui chuli, 2015 选用煤渣和沙子两种基质进行等温吸附和吸附动力学试验,并结合表面流人工湿地处理含磷废水的效果,研究了煤渣和沙子对磷的吸附特性以及两种基质在表面流湿地中的除磷效果。结果表明:吸附实验中,Freundlich和Langmuir方程均能较好地拟合两种基质对磷的吸附特性,一级反应动力学方程能够很好拟合沙子的吸附动力学曲线,煤渣的动力学拟合情况较差。以煤渣为基质的表面流人工湿地对磷的平均去除率(35.79%)低于以沙子为基质的表面流人工湿地对磷的平均去除率(48.25%),并且沙子湿地除磷的稳定性好于煤渣湿地。

Shuitu Baochi Xuebao, 2019 针对滨海盐渍化土壤水稻种植过程中根系生长受盐碱胁迫，导致养分利用率低的问题。采用田间试验研究了有机肥与磷肥配施对滨海盐渍化土壤水稻不同生育期根系生长、水稻产量及养分利用率的影响。试验采用双因素设计，3个碳水平：（1）C0，无碳；（2）C1：低碳，450 kg/hm2；（3）C2：高碳，900 kg/hm2；3个磷水平：（1）P0：无磷；（2）P1：低磷，P2O5 64 kg/hm2；（3）P2：高磷，P2O5 128 kg/hm2。结果表明，在水稻成熟期，低碳低磷（T5 ...
