Shuitu Baochi Xuebao, 2022 为明确黄土高原地区植被长期恢复的土壤碳汇效应,采用时空互代的方法,研究子午岭地区150年以来8个植被演替序列的土壤有机碳含量及储量的变化特征,分析影响土壤有机碳储量变化的植被因素。结果表明:从农地演替到气候顶级辽东栎(Quercus wutaishanicaMary.)群落,土壤有机碳含量和储量明显增加,表现为演替前期(草本群落)快速增加,后期(乔木群落)趋向稳定的变化特征。剖面上来看,随着土层加深,土壤有机碳含量迅速减少。0—5 cm土层土壤有机碳含量与5—20,20—40 cm土层差异显著(P＜0 ...

Functional Ecology, Volume 40, Issue 2, Page 534-552, February 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Non‐structural carbohydrates (NSC) are critical mediators of plant adaptation to fluctuating light environments. They are tightly coordinated with plant economic strategy, that is, leaf economics spectrum (LES) and root economics spectrum (RES).

Porous Mn2O3@C Cathode With High Activity and Long Lifespan for Aqueous Zinc Ion Batteries
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Manganese‐based oxides are widely employed as cathode materials for aqueous zinc ion batteries (AZIBs) due to their low toxicity and high theoretical specific capacity. However, their inherent poor electrical conductivity, coupled with the dissolution of manganese into the electrolyte, often leads to structural degradation of the cathode.

Haiyang yu huzhao牡蛎礁是蓝色碳汇的重要组成部分，其通过钙化作用、生物同化作用以及生物沉积作用等来完成对碳的封存，以达到碳中和的目的。目前我国关于热带天然牡蛎礁碳库储量的研究较少。文章评估了海南岛近岸4处典型天然牡蛎礁(文昌龙楼、文昌会文、昌江昌化和儋州海头)的碳库储量，并分析了其时空变化特征及其原因。结果表明，4处礁区的现存总碳库储量为18 734.6 t C，长期总碳库储量为16 883.08 t C。其中海头、昌化、龙楼和会文的现存碳库储量及单位面积平均碳库储量分别为15 923.42 t C (3.46 kg C/

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Sodium‐ion capacitors (SICs) offer high energy and power density with long cycle life, but developing kinetically compatible electrodes remains challenging. This work developed a simple and sustainable strategy to synthesize homologous carbon electrodes from the inner shells of durian husks (ISDH) for high‐performance SICs.

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Metal sulfide, as a type of lithium/sodium‐ion battery material, possesses merits such as high capacity and low cost. Nevertheless, it is prone to structural changes during the cycling process, leading to volume changes and affecting electrochemical performance.

Effects of crop species on soil functions and soil multifunctionality are species‐specific
Functional Ecology, Volume 39, Issue 9, Page 2354-2369, September 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Soil multifunctionality is essential for sustainable agriculture, as soils not only need to support crop growth but also maintain soil biodiversity and sustain other critical ecosystem functions.
