Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Vanadium redox flow batteries show considerable promise for energy storage, yet their overall performance is still hindered by the limited electrochemical activity of graphite felt (GF) electrodes. Herein, using folic acid and metal salts as precursors, M–N–C functionalized carbon nanosheets (M–NC, M=Co, Fe, and Ni) were prepared via a ...

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Capacitive deionization (CDI) using activated carbon (AC) electrodes holds great promise for seawater desalination, yet its practical application is severely constrained by the intrinsic hydrophobicity of carbon surfaces. Herein, we propose a solid‐state superhydrophilic modulation strategy that physically wet‐mixes superhydrophilic MOF ...

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 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 ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Regulating oxygen vacancies (Ov) in SnO2 to facilitate high‐efficiency carbon dioxide electroreduction reduction reaction (CO2RR) is still a significant challenge. Therefore, a strategy based on Ag‐induced interfacial electron transfer was proposed to modulate Ov in SnO2 for CO2 electroreduction. The prepared Ag/SnO2 with an optimal Ov content

, 2017 表面电势是微纳流控芯片中流体流动的重要参数。本文介绍了基于AFM胶体探针技术测量液固界面DLVO力并进一步测量表面电势及表面电荷密度的方法。本文改进了胶体探针制作的技术手段，并提出用双探针法测量胶体探针的弹性系数。在0.1-1mM浓度范围内的NaCl溶液中，测量了硅、二氧化硅和氮化硅液固界面双电层内的DLVO力及表面电势。实验结果表明胶体探针技术可以很好地测量液固界面的DLVO力，尤其对静电力指数变化段非常敏感。通过DLVO力曲线可以间接测量表面电势、表面电荷密度等重要参数 ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT A central challenge in high‐performance photoelectrochemical (PEC) systems is mitigating the intrinsic limitations in photogenerated carrier separation and transport, while enabling efficient broad‐spectrum solar harvesting. Inspired by the synergistic effect between plasmonic resonance and heterojunction built‐in electric fields, a ternary ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT High‐yield photocatalytic H2O2 production in sacrificial agent‐free pure water constitutes a critical bottleneck requiring urgent advances in energy catalysis. Although ZnIn2S4 (ZIS) exhibits favourable visible light absorption, it is plagued by severe bulk charge carrier recombination and scarce accessible surface‐active sites.

Dianci bileiqi, 1993 据美国《IEEE Trans.Elec.Insul.》杂志报道。对在SF6气体中表面电荷对绝缘子冲击闪络的影响进行了研究。由电晕放电电源使绝缘子表面产生线性分布或均匀分布的多极性电荷,或者具有相邻电极（同号电荷）或相反电极（混合电荷）的双极电荷。拥有分裂电极的试验装置借助电容式探测器可以测定整个绝缘子的表面。研究得出了如下结论:使阴极电场增大的表面电荷分布对在SF6气体中的绝缘子表面的冲击闪络有重大影响;当均勺分布或线性分布的正极性电荷的密度大于25μC/m～2时,表面冲击放电强度减小 ...
