Functional Ecology, Volume 40, Issue 6, Page 1725-1739, June 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Root exudates play a key role as signals and nutrients in mediating plant–microbe communication. However, critical knowledge gaps remain regarding how root exudates mediate soil–microbe–plant interactions to regulate crop yield under long‐term straw mulching combined ...

Functional Ecology, Volume 40, Issue 6, Page 1878-1891, June 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecological communities are stressed by rapid and complex anthropogenic changes, threatening the persistence of biotic interactions and ecosystem functioning. Plant–pollinator communities, for instance, undergo structural transformations as a result of land‐use change ...

Gongye shui chuli, 2015 利用溶胶凝胶法实现了N掺杂改性的TiO2在粉煤灰漂珠(FAC)表面的负载,成功制备出N-TiO2/FAC复合光催化剂。以亚甲基蓝为降解对象,研究了不同煅烧温度、不同N掺杂量的复合光催化剂在可见光条件下的光催化活性与反应动力学性能。试验表明:煅烧温度为450 ℃,N掺杂量为25%的条件下制备的N-TiO2/FAC光催化降解亚甲基蓝的效果最优,对亚甲基蓝的降解效率比N-TiO2高10%,比TiO2/FAC高40%,且该催化剂漂浮于水面可通过相分离得以回收。

Ecology and Evolution, Volume 16, Issue 5, May 2026.This study reveals a shift in woody plant community assembly from competitive exclusion in early succession to habitat filtering in later stages within karst areas. Environmental distance (80.54%) contributed significantly more than geographical distance (9.95%), providing strong quantitative evidence that niche processes, particularly habitat ...

Shuitu Baochi Xuebao, 2007 不同施氮措施条件下，对保护地黄瓜生育期内氮素吸收利用效率、氮素淋洗损失进行了研究，同时也研究了不同处理对黄瓜产量及品质的影响。试验结果表明，传统施肥处理（2100kg／hm^2）与推荐施肥处理（900kg／hm^2）之间氮素吸收量没有显著差异，传统施肥处理中大量的氮肥没有用于促进黄瓜对养分的吸收利用，其氮肥利用率、农学利用率以及生理利用率都很低，每千克纯氮增产只有2．06kg，91．65％的氮素以各种途径被损失掉，其中土壤硝态氮淋洗是主要形式。同时研究发现，传统施肥处理过量氮肥施用阻碍其它营养元素的吸收，

Gaoya dianqi, 1993 首先考察了16种常用气体构成的SF6混合气体。通过分析其液化温度、介电强度、电弧产物的毒性及腐蚀性、热物理性质和传输特性以及价格成本,认为SF6/N2混合气体可以代替纯SF6做为GCB（气体断路器）在低温环境下的灭弧介质。之后,研究了SF6/N2的开断特性。研究结果证明,SF6/N2混合气体具有较好的开断特性。

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Integrating light emission and electromagnetic wave (EMW) absorption into a single material opens up possibilities for multienvironmental applications. Herein, we propose a novel “molecular engineering‐pyrolysis conversion” strategy to construct a bifunctional system with tunable photoluminescence and efficient EMW absorption performance.

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Composite materials hold significant potential for abrasive sealing, yet composite materials used for abrasive sealing fall short in service durability under extreme environments. Here, a controllable strategy for adjusting pore structure is proposed, aiming to design a YSZ(ESP)/BN@ZrO2‐polyester coating with hybrid micron/nanometer ...
