Composite‐Field Annealing Enables Superior High‐Temperature Noise Stability in Fluxgate Sensors With Co‐Rich Amorphous Microwires

open access: yesRare Metals, EarlyView.
ABSTRACT Fluxgate sensors with Co‐rich amorphous microwires, widely used for their low noise in magnetic field measurements, encounter significant challenges in high‐temperature environments such as well drilling and geological exploration. Prolonged thermal aging degrades the performance of Co‐rich amorphous microwires, resulting in increased noise ...

黄土丘陵沟壑区不同退耕模式的土壤水文性质影响对比

open access: yesShuitu Baochi Xuebao, 2021
为系统评价黄土丘陵沟壑区在"退耕还林(草)"工程实施后不同退耕模式下的土壤水分涵养功能,选取0-200 cm土层的蓄水量、土壤含水量分层比、土壤水吸力和土壤含水量年际变化率作为土壤层水分蓄存、渗透、保持和稳定性的表征指标,分别对比了不同退耕模式下的土壤水文性质。结果表明:(1)各退耕模式下土壤蓄水量差异显著,撂荒模式的土壤蓄水量最高,为还灌和还乔模式下的1.6,1.7倍;(2)还乔模式下表层土壤水分的渗透性最优,深层土壤水分的渗透潜力最大;(3)各退耕模式的土壤持水性差异显著 ...

Oxygen Vacancy Engineering of Ultrafine ZnAl2O4 Nanoparticles as a Robust Protective Layer for Dendrite‐Free and Long‐Lifespan Aqueous Zn Metal Anodes

open access: yesRare Metals, EarlyView.
ABSTRACT Aqueous zinc‐ion batteries (AZIBs) hold great promise for safe and sustainable energy storage, but their commercialization is impeded by severe Zn dendrite growth and interfacial instability. To address these challenges, we propose a defect engineering strategy employing ultrafine ZnAl2O4 (ZAO) nanoparticles (∼5 nm) with oxygen vacancy defects
