, 2021 于2018年在晋北典型农牧交错带盐碱化草地设置增减降水和氮添加处理试验,2019年生长季(5—9月)采用原位顶盖PVC埋管法测定不同水、氮处理下土壤净氮矿化速率,研究盐碱化草地土壤净氮矿化速率对降水格局变化和氮沉降的响应。结果表明:土壤净氮矿化速率表现出明显的季节动态。单独增减降水(±50%)和氮添加(10 g·m~(-2)·a~(-1))以及氮添加+增加50%降水处理对土壤净氮矿化速率影响不显著,氮添加+减少50%降水处理显著提高土壤净硝化速率和净氮矿化速率,分别提高10.8和8.6倍 ...

Organ‐specific ozone and nitrogen legacies strengthen substrate control over litter decomposition
Functional Ecology, Volume 40, Issue 8, Page 2548-2559, August 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Elevated tropospheric ozone (O3) and nitrogen (N) deposition are concurrent atmospheric changes that strongly influence terrestrial carbon cycling, yet their combined effects on below‐ground decomposition remain poorly understood.

Global Change Biology, Volume 32, Issue 7, July 2026.Grassland recovery following nutrient cessation is asymmetric and strongly shaped by nutrient enrichment history. Higher nutrient addition rates and longer enrichment duration caused larger departures from control conditions, with biomass recovering more rapidly than species richness over decadal timescales.

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT The development of lightweight, high‐attenuation, and broadband carbon‐based electromagnetic wave absorbers is hindered by the intrinsic trade‐off between impedance matching and dielectric dissipation. Herein, we report a facile and scalable synthesis of N‐doped lignin‐derived interconnected porous carbon (Nx‐LIPC) via hydrogen‐bond self ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Dielectric polymers commonly suffer from severe performance degradation above 150°C, hindering advanced power systems. Herein, we demonstrate a polyetherimide (PEI) nanocomposite that overcomes this by mimicking the gradient architecture of nacre and bamboo, incorporating a continuous vertical gradient of fluorinated boron nitride nanosheets ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT The development of structurally stable anodes with high capacities and long cycle lives is essential for the development of potassium–ion batteries. Conversion‐type anodes have attracted considerable attention in potassium–ion batteries (PIBs) due to their high theoretical capacities.

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 ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT The dual challenges of environmental sustainability and rising energy needs underscore the necessity for high‐energy‐density batteries, making lithium–sulfur (LSB) systems with their high theoretical capacity highly attractive. However, the polysulfide shuttle, coupled with inherent kinetic limitations in the sulfur reduction reaction ...
