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 ...

多源地形数据对地形因子计算及土壤侵蚀评价的影响

open access: yes, 2020
土壤侵蚀预报模型是定量评价土壤侵蚀的科学依据与技术工具。采用通用土 壤流失方程USLE 或其衍生模型评价区域土壤侵蚀时,地形因子(坡长坡度因子 等)通常使用由地形图或航空运载数据集生成的数字高程模型DEM 估算。DEM 数据精度显著影响计算的地形因子可靠性和准确性,从而极大地影响了土壤侵蚀 评价精度,严重制约了土壤侵蚀模型应用。本论文选取我国五个水蚀二级类型区 (东北黑土区、北方土石山区、西北黄土高原区、西南土石山区和南方红壤丘陵 区)中的小流域作为研究对象,采用数理统计、分位数映射、中国土壤流失方程 ...

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.

用自然三角形单元计算应力强度因子

open access: yes, 1984
用有限元法计算应力强度因子的各种奇异元中,由八节点或十二节点的四边形等参数单元所派生的奇异元最为简单,因为这种单元就是原有的等参数单元,无须程序变动,只要适当地改变裂纹顶点单元的边中点的坐标,就可使应变具有γ~(-1/2)的奇异性。这种单元是协调单元,满足收敛准则,当有人提出过渡单元概念以后,使计算结果更为精确,因此,这种单元是工程中广泛应用的一种计算应力强度因子的奇异元。与四边形等参数单元相应的一族单元是自然三角形单元。下面证明六节点的二次三角形单元和十节点的三次三角形单元 ...

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.
