张衡一号卫星探测的赤道附近电场分布及其与电离层分布的关系

open access: yesKongjian kexue xuebao, 2023
利用张衡一号卫星搭载的电场探测仪(Electric Field Detector,EFD)获得的VLF频段2019年电场功率谱数据,研究赤道附近区域近东西向电场的背景分布、季节变化以及与电离层背景的关系。结果表明:白天电场背景在赤道及其附近随季节呈不同波形结构,以3波、4波为主;夜间电场背景规律性稍差,仍呈随季节变化的经向波形结构分布特征;白天电场背景与电离层背景的季节变化呈高度正相关性,春秋季为峰值;夜间电场背景的季节变化特征是夏冬季峰值,与夜间电离层背景整体上呈负相关性 ...

Bio‐Inspired Continuous Gradient Nanocomposites for Ultrahigh‐Temperature Dielectric Energy Storage at 150°C–200°C

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Dielectric polymers commonly suffer from severe performance degradation above 150°C, hindering advanced power systems. Herein, we demonstrate a polyetherimide (PEI) nanocomposite that overcomes this by mimicking the gradient architecture of nacre and bamboo, incorporating a continuous vertical gradient of fluorinated boron nitride nanosheets ...

高压开关柜三维瞬态电场计算研究

open access: yesGaoya dianqi, 2020
高压开关柜运行过程中承受的不均匀电场将会导致绝缘介质内部或表面出现高场强区域,危害电力设备的安全可靠运行。针对12 kV铠装型移开式交流金属封闭开关设备,文中利用Ansys Maxwell建立了开关柜电缆室三维瞬态电场有限元仿真模型,获得了开关柜电缆室在10 kV系统标称电压下的电场分布特征和电场集中区域。在此基础上,研究了不同母线电压值、三相电压不平衡对触头盒、避雷器、接地开关支柱绝缘子以及母线相间处最大电场强度单元节点的影响。仿真结果表明:触头盒内部、避雷器高压端 ...

Structural Modulation of Magnetic Softness in Fe‐Based Amorphous Alloys via Pulse Current Training

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Fe‐based amorphous alloys, despite their intrinsically low magnetocrystalline anisotropy, suffer from quasi‐dislocation dipoles and localized stress fields that impede domain‐wall motion and increase coercivity. Here, we introduce pulse current training (PCT) as an energy‐efficient technique to overcome these limitations in a Fe76Si9B10P5 ...

Political Cycles, Electricity Policy, and Mexico's Economy

open access: yesLatin American Policy, Volume 17, Issue 2, June 2026.
ABSTRACT Electricity reform in Mexico should stimulate economic growth, improve energy efficiency, and reduce greenhouse gas emissions. This article evaluates the successes and failures of reform and draws lessons across political cycles by analyzing changes in political dynamics—often tied to policy reversals—and the legal framework during the pro ...

Superior Abrasibility of YSZ(ESP)/BN@ZrO2‐Polyester Composite Sealing Coating Reinforcing With Hybrid Micron/Nanometer Multiscaled Pore Structure

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Composite materials hold significant potential for abrasive sealing, yet composite materials used for abrasive sealing fall short in service durability under extreme environments. Here, a controllable strategy for adjusting pore structure is proposed, aiming to design a YSZ(ESP)/BN@ZrO2‐polyester coating with hybrid micron/nanometer ...

Synergistic Activation of the Inert (001) Facet in Janus ZnIn2S4 Through Co 3d and P 3p Orbital Hybridization for Superior Photocatalytic Hydrogen Evolution

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT The Janus structure of ZnIn2S4 (ZIS) endows it with an intrinsic built‐in electric field that effectively drives photogenerated charge separation. However, this very structure also renders the predominant (001) facet (In–S termination) catalytically inert due to its low electron density and high energy barrier for the hydrogen evolution ...

From Dendrite Accelerator to Suppressor: Engineering a Self‐Assembled Monolayer for Ultrafast and Dendrite‐Free Zinc Deposition

open access: yesRare 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.
