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 ...

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 ...

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 ...

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 ...

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
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
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.
