Shuitu Baochi Xuebao, 2004 从适用于陡坡的水动力学模型出发,研究坡面水流细沟侵蚀临界状态的判断方法。讨论了坡长、坡度、坡面投影长对细沟侵蚀的影响,采用临界摩阻流速随坡度变化、临界摩阻流速不随坡度改变两种假定分别进行模拟计算,以摩阻流速作为判别坡面细沟流侵蚀临界状态的水动力学指标,在给定的坡面尺寸、净雨强和初始微地形条件下,计算得出了细沟流摩阻流速达到临界值时所对应的坡度。

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT The use of Ti6Al4V alloy in dental implantation is constrained by its high elastic modulus and biological inertness, which lead to delayed osseointegration and a high failure risk. Additionally, its chemical incompatibility with hydroxyapatite (HA) impedes the development of stable bioactive composites.

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Lithium‐rich manganese‐based cathodes (LRM) deliver high discharge capacities beyond 250 mAh g−1, but their practical deployment is restricted by irreversible oxygen redox, structural reconstruction, sluggish kinetics and unstable cathode‐electrolyte interfaces (CEI). Here, we develop a colloid‐assisted anchoring‐diffusion engineering strategy

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Developing rapid, precise gas sensors for Listeria monocytogenes (LM) biomarker detection faces challenges due to suboptimal gas‐solid interactions. Herein, we report the rational synthesis of amino‐functionalized mesoporous SiO2 hollow nano‐doughnuts (MS‐2‐NH2‐2) via modification with (3‐aminopropyl) trimethoxysilane (AAPTMS), which enables ...

Bidirectional Interfacial Chemical Regulation Enables Durable Aqueous Zn‐I2 Batteries
Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Aqueous Zn‐I2 batteries hold great promise for large‐scale energy storage, yet their practical deployment is hindered by coupled interfacial instabilities at both electrodes, where Zn‐anode parasitic reactions and cathodic polyiodide shuttle mutually aggravate each other.

Gaoya dianqi, 2011 XPLE电力电缆因其优异的机械性能和电绝缘性能得到广泛的使用,在交联电缆接头安装过程中,对交联聚乙烯主绝缘表面进行打磨会使接头交联聚乙烯—硅橡胶界面产生不同的粗糙程度,但是对存在于两个有机绝缘之间的接触面的电绝缘强度的研究很少,笔者针对交联聚乙烯电力电缆接头的交联聚乙烯和硅橡胶两绝缘界面经常出现放电光的现象,建立了电痕破坏实验平台,用不同型号的砂纸对XPLE片横向和纵向打磨制备实验样品,采用高速相机对发生在交联聚乙烯和透明硅橡胶界面上的放电光进行记录。结果表明:界面粗糙度越大 ...

Functionalized Silica‐Constructed Self‐Supporting Composite Separator for Lithium Metal Batteries
Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Lithium metal batteries (LMBs) are considered highly promising next‐generation energy storage systems owing to their exceptionally high theoretical specific capacity and ultralow electrochemical potential. Nevertheless, the practical deployment of LMBs is still severely restricted by the uncontrollable formation and propagation of lithium ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT The central challenge in photocatalysis is to direct photogenerated electrons and holes toward the simultaneous and efficient production of hydrogen and value‐added chemicals. To address the pronounced charge recombination and sluggish surface kinetics of ZnIn2S4 nanoflowers, we construct a ternary photocatalyst synergistically decorated with ...
