Two‐Dimensional Catalysts for Enhanced Hydrogen Storage in Magnesium Hydride: Materials, Mechanisms, and Future Perspectives

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Magnesium hydride (MgH2) is a promising solid‐state hydrogen storage material due to its high gravimetric capacity and excellent reversibility. However, its practical application is hindered by high thermodynamic stability and sluggish reaction kinetics.

Anchoring Polyoxometalate (PMo11Fe) on ZnO Nanosheet for Construction of a Novel S‐Scheme Heterojunction Toward Efficient Photodegradation of Levofloxacin Antibiotics

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Currently, the photocatalytic performance of ZnO has been severely limited by its weak light response ability and sluggish charge carrier dynamics, which considerably hinder its extensive application in photocatalytic fields. Herein, through anchoring the synthesized K6PMo11FeO40·nH2O (PMo11Fe) onto ZnO nanosheets, a novel S‐scheme ...

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

open access: yesFunctional Ecology, Volume 40, Issue 9, Page 2726-2736, September 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Revealing the Roles of Electrolyte Concentration on Transition Metal Dissolution and Reaction Pathway of Anion Adsorption Pseudocapacitance

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Conventional lithium‐ion battery cathodes predominantly rely on reversible lithium intercalation in bulk, which inevitably induces phase transitions, transition metal migration, and voltage decay. Electrolytic anion adsorption pseudocapacitance provides a chance for bypassing these issues via a surface‐dominated reaction, especially in ...

Synergy Effects of Dual‐Gel‐Assisted Structural Engineering and Bimetallic Doping Regulation Realize Ultrastable High‐Rate Performance of NASICON Cathodes for Sodium‐Ion Batteries

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Na‐superionic‐conductor‐type (NASICON) Na4MnV(PO4)3 (NMVP) is an appealing cathode for sodium‐ion batteries (SIBs), but its application is hindered by Jahn–Teller distortions, sluggish Na+ kinetics and poor conductivity, leading to rapid capacity fade.

Organ‐specific ozone and nitrogen legacies strengthen substrate control over litter decomposition

open access: yesFunctional 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.

长白山地区黄鼬冬季生境选择

open access: yes野生动物学报, 2008
2007年12月在吉林省蛟河市采用雪地足迹链跟踪法,对长白山地区黄鼬冬季120个利用样方的生境变量进行因子分析,应用主成分分析法,迭代8次,使用Varimax最大方差法进行因子旋转,使用回归方法计算因子得分,根据因子的特征值大于1得出3个公因子:第一为食物因子,第二为地形因子,第三为气候因子。3个因子的累计贡献率大于85%。黄鼬主要选择食物丰富度高、利于捕食、气候条件好的地方作为栖息场所。

Perceived costs as drivers of wildlife management preferences in rural Tanzanian communities

open access: yesConservation Biology, Volume 40, Issue 4, August 2026.
Abstract Effectively managing human–wildlife interactions is crucial for fostering coexistence on shared landscapes. Management options are most effective when aligned with the preferences of people directly affected by wildlife, yet little is known about how socioecological factors influence these preferences.

基于鲸鱼算法的风机接地网优化设计

open access: yesGaoya dianqi, 2023
接地系统是风电机组防雷设计保护的重要部分,接地网的几何形状关乎雷击冲击特性。传统等间距接地网遭受雷击后产生巨大的接触电压,严重危害机组的正常运转,而利用优化算法求解最优压缩比构建不等间距接地网能有效降低接触电压。文中提出基于混沌动态权重因子和非线性收敛因子的优化鲸鱼算法(FWOA),求取最优压缩比,解决传统粒子群算法(PSO)早熟和寻优精度低等缺陷,在ATP-EMTP中搭建集桨叶、塔筒、电缆、接地网为一体的风机全局波阻抗模型,考虑火花效应和增设垂直导体对暂态电位的影响的基础上 ...
