Alleviation of phosphorus rather than nitrogen limitation driven by permafrost and landscape effects on Dahurian larch forests

Functional Ecology, Volume 40, Issue 8, Page 2590-2601, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Permafrost thaw is reshaping nutrient dynamics in boreal forests, but its impacts on tree nutrient limitation and functional strategies remain poorly understood. Clarifying these responses is crucial for predicting the response of boreal forests to climate change.

一种单原子钯负载氮化碳催化剂及其制备和在去除NO中的应用

, 2020
本发明属于光催化材料制备与环境污染物处理领域，公开了一种单原子钯负载氮化碳催化剂及其制备和在去除一氧化氮的应用。本发明采用光还原法合成的单原子钯负载氮化碳去除一氧化氮。该法采用尿素作为氮化碳的前驱体，然后使氮化碳和钯源充分混合、光照还原，得到单原子钯负载的氮化碳。而且相比于氮化碳，单原子钯负载氮化碳对一氧化氮具有良好的去除效果和稳定性，对一氧化氮具有58％的去除率，材料循环使用120min而性能不衰减。单原子钯负载氮化碳对一氧化氮终产物硝酸根有更高的选择性 ...

Leaf C:P ratio as a universal indicator of photosynthesis in subtropical woody species: Stoichiometric thresholds and metabolic trade‐offs

Functional Ecology, Volume 40, Issue 7, Page 2332-2344, July 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The stoichiometric ratios of carbon (C), nitrogen (N) and phosphorus (P) serve as important indicators for assessing nutrient balance in forest ecosystems, but their relationships with photosynthetic dynamics require deeper characterization.

低碳氮比下MABR同步硝化反硝化过程的构建

Gongye shui chuli, 2020
以市政污水为研究对象，应用曝气膜生物反应器（MABR）技术探讨同步硝化反硝化（SND）过程的构建及其在不同低碳氮比下运行的特点，为今后应用MABR处理低碳氮比废水提供有益参考。结果表明：曝气压力为0.049 MPa，HRT为12 h，碳氮比为6.3~8.0时，经过45 d的连续运行，成功实现了稳定的SND工艺，SND率达87.48%，且不存在亚硝酸型硝化；当碳氮比由4.4降至2.3时，平均SND率由87.34%降至84.53%；碳氮比降低对生物膜与主料液菌群多样性影响较小，对优势属种类影响较大。

Nitrogen–Doped Carbon Nanotube–Supported Ni3Se4–CeO2 Heterojunctions With Multi–Orbital Hybridization for Efficient Hydrogen Evolution Reaction

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Engineering of the catalyst interface and modulation of transition–metal d–band play critical roles in the electrocatalytic hydrogen evolution reaction (HER). Herein, a synthetic strategy is developed to fabricate nitrogen‐doped carbon nanotubes (N–CNTs)–supported Ni3Se4–CeO2 heterojunction catalysts through a facile chemical vapor deposition (

地膜覆盖对黄土高原旱作春玉米田土壤碳氮组分的影响

Shuitu Baochi Xuebao, 2017
基于2 a田间试验，研究了地膜覆盖对旱作春玉米田土壤有机碳、全氮及其组分的影响，试验包括地膜覆盖玉米田、无覆盖玉米田和裸地休闲3个处理，分层测定了0—40 cm土层有机碳、全氮、颗粒有机碳氮、潜在矿化碳氮和微生物量碳氮含量。结果表明：在0—40 cm土层，各处理间土壤有机碳和全氮含量均无显著差异。与不覆盖相比，地膜覆盖处理0—40 cm土层颗粒有机碳氮及其所占比例分别降低了29.0%，33.3%，29.9%，35.7%；0—10 cm土层潜在矿化碳及其所占比例分别降低了17.8%和16.1 ...
