Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Aqueous zinc‐ion batteries are plagued by anode challenges such as dendrite growth and corrosion, which stem from intrinsic surface heterogeneity. Although constructing a homogeneous interfacial layer is a promising strategy, conventional electrolyte additives often suffer from incomplete or unstable coverage.

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Thermally driven hydrogenation of CO2 to light olefins (C2=–C4=) using metal oxide‐zeolite tandem catalysts is an effective strategy for achieving carbon neutrality. However, progress in this area is constrained by zeolite pore transport limitations, acid‐site inactivation, and surface carbon poisoning.

Shuitu Baochi Xuebao, 2017 为明确东北黑土区农田土壤风蚀的主要影响因素，通过室内模拟试验，对比分析了黑土在不同风速（5～14 m/s）、土壤含水量（2%～11%）以及秸秆覆盖率（0～80%）下的风蚀速率差异，进而分析了风蚀速率与各因素之间的数量关系。结果表明，黑土起沙风速略大于5 m/s，其风蚀速率随风速增大呈指数增加，风速14 m/s（含水量2%）时的风蚀速率比8 m/s时增加了11.6～42.7倍。黑土风蚀速率随土壤含水量升高呈先增加后降低趋势；在土壤含水量小于5%时随含水量升高而逐渐增加，至含水量5%时达到峰值并逐渐降低 ...

Functional Ecology, Volume 40, Issue 4, Page 983-1000, April 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Organic phosphorus mineralization is a critical process in the phosphorus cycle, governing phosphorus bioavailability for plants. The PhoD gene, which encodes the key enzyme alkaline phosphatase, serves as a valuable biomarker for this process.

Distribution, scale, and drivers of mass mortality events in Europe's freshwater bivalves
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Mass mortality events (MMEs) are decimating populations and compromising key ecosystem functions around the globe. One taxon particularly vulnerable to MMEs is freshwater bivalve mollusks. This group has important ecosystem engineering capacities and includes highly threatened and highly invasive taxa.

Shuitu Baochi Xuebao, 2016 通过向土壤中均匀添加不同含量（0，10，20，30，40，50，60 g/kg)凹凸棒土（ATP）来研究其对土壤水分运动及土壤水动力学参数的影响。结果表明，随着ATP含量的增大，土壤入渗速率、累积入渗量减小，Philip公式中的吸渗率S和稳渗率A均减小，Kostiakov公式中入渗系数K减小，经验指数β增大；土壤持水性随着ATP含量的增加而增大，van Genuchten公式中滞留含水率θr减小，饱和含水率θs增大，进气值的倒数α增大，形状系数n减小；利用van ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Low conductivity, slow ion‐diffusion, and limited reactive sites are common problems in electrocatalysts and electrode materials. In this study, a complex NiTe–CoTe heterojunction with abundant Te vacancies embedded in N, P, and F co‐doped hollow carbon nanorods (NiTe1−x–CoTe1−x/NPFC) was fabricated via a simple ionic liquid‐assisted ...
