Jellyfish blooms restructure plankton dynamics and trophic linkages in coastal waters

open access: yesFunctional Ecology, Volume 40, Issue 5, Page 1443-1460, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Jellyfish blooms are increasing globally in frequency and intensity, introducing complex ecological interactions, yet the mechanisms by which they alter ecosystem structure remain poorly characterized due to a lack of sustained field observations.

Highly Stable Aqueous Zinc Anodes Enabled by Synergistic Modulation of Interface and Solvation Structures

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT The stability of aqueous Zn2+ batteries is severely hindered by parasitic reactions at the Zn anode/electrolyte interface. Herein, itaconic acid (IA) is introduced as an effective electrolyte additive to achieve a highly stable zinc anode. Remarkably, IA concurrently modulates both the zinc anode/electrolyte interfacial structure and the Zn2 ...

High‐Value Targeted Conversion of Copper Slag as LiFePO4 Material for Lithium‐Ion Batteries

open access: yesRare 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.

黄土区土壤水分循环水分研究

open access: yesShuitu Baochi Xuebao, 1995
土壤水分循环水平是指一定时期内土壤水分波动变化的平均状态。它是判别土壤水分循环状况优劣的标志之一,土壤水分循环达到平衡状态,并不一定说明土壤水分循环处于最佳状态。只有同时对土壤水平稀状态水分循水平进行,杂技和有可能作出可靠的判断,在一定程度上,生态系统的循环水平可以通过人为措施来调节。

Elevation, soil pH and calcium availability shape regional and local scale spatial patterns of PhoD gene abundance in tropical and subtropical forests

open access: yesFunctional Ecology, Volume 40, Issue 4, Page 983-1000, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Organic phosphorus mineralization is a critical process in the phosphorus cycle, governing phosphorus bioavailability for plants. The PhoD gene, which encodes the key enzyme alkaline phosphatase, serves as a valuable biomarker for this process.

旁流弱酸处理应用于循环冷却水的试验研究

open access: yesGongye shui chuli, 2010
循环冷却水采用旁流弱酸处理后,由于工艺改变了循环水运行的碱度、硬度,对判断循环水系统是否结垢带来了困难。通过在循环冷却水的动态模拟试验过程中监测凝汽器管的污垢热阻,循环水的碱度、硬度、pH的变化以及试验结束后观察试片的表面状态等方法,对循环水系统是否结垢进行了探讨。
