基于复合钝化剂施用植物轮作模式对农田土壤Cd和As污染的修复

open access: yesShuitu Baochi Xuebao, 2022
镉(Cd)和砷(As)是土壤环境中广泛存在的重金属污染物,具有不可降解性和生物累积性的特点,应及时开展Cd和As污染的修复工作。研究以湖南中、轻度Cd和As污染农田土壤为对象,选取当地优势植物。通过田间试验,添加生物炭与纳米零价铁的复合钝化剂,利用不同植物(油菜-蚕豆、玉米-苎麻)配套种植模式,探讨基于复合钝化剂施用植物轮作模式对土壤中Cd和As污染的修复效果。结果表明:(1)间作种植模式(蚕豆-油菜、玉米-苎麻)更有利于土壤中Cd和As的固定,试验土壤中Cd和As的最佳固定效果依次为原供试土壤的45 ...

Directed Construction of a Synergistic Li3P‐LiF Inorganic Solid Electrolyte Interphase Toward Stable Silicon Anodes

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Silicon–carbon composite anodes offer exceptionally high energy density, but their practical application is severely constrained by the structural instability and continuous evolution of the solid electrolyte interphase (SEI). In this work, moving beyond conventional LiF‐enrichment strategies, we propose a directional regulation approach based

钝化外形对旋成体气动性能的影响

open access: yes, 2014
为考察钝化外形对高超声速飞行器气动性能的影响,基于CFD分析,针对典型旋成体比较2种不同钝化外形(钝化半径均匀/非均匀)的气动性能.结果表明:在较小的钝化半径/高度下,由于前缘流向投影面积占整个旋成体流向投影面积比例较小,前缘气动性能对整个旋成体气动性能影响不大;但是,随着钝化半径/高度的增加 ...

Al2O3膜钝化晶体管的快中子辐照效应

open access: yes四川大学学报. 自然科学版, 1989
由于Al2O3钝化膜具有密度大,对Na+离子的阻挡能力强,介电常数约为SiO2的二倍等优点,因此,我们采用直流反应溅射法对3CK和3CG型小功率管进行了Al2O3膜的钝化处理,将钝化了的和未钝化的晶体管进行高能电子,快中子辐照.电子辐照结果表明:钝化晶体管比未钝化晶体管抗辐射能力提高了近半个数量级.

Effect of Worm‐Like Amorphous Phase on Corrosion Resistance and Antibacterial Properties of NiTiCu Alloy

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT By adding CuO, the worm‐like amorphous phase and atomic clusters were simultaneously introduced, enabling the (Ni40Ti40Cu20)99.9O0.1 alloy micron columns to exhibit a uniform flow strain of over 40% and a strength of over 2.5 GPa during compression.

不同钝化剂组合对土壤铬铜赋存形态及在水稻中积累的影响

open access: yesShuitu Baochi Xuebao, 2019
为了筛选出能有效抑制水稻各部位吸收积累Cr和Cu的有机和无机材料钝化剂组合,选取水稻土以盆栽试验研究了15种钝化剂组合对土壤Cr和Cu赋存形态及水稻各部位吸收积累Cr和Cu的影响。结果表明:15种钝化剂组合施用使土壤pH上升0.25~1.04,土壤阳离子交换量增加2.65%~50.96%,土壤有机质含量增加0.22%~17.20%,土壤可交换态Cr含量降低35.21%~55.63%;除生石灰+钝化剂4+鸡粪组合使土壤可还原态显著增加外,其他组合的土壤可还原态Cr无显著变化 ...

Unveiling Temperature‐Dependent Corrosion Behaviors of FeNiCrMoCBY Amorphous Alloy Coatings In Spent‐Fuel Storage Environments

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT A comparative study was performed to elucidate the temperature‐dependent corrosion kinetics and the semiconductor/structural characteristics of the passive film formed on Fe40Ni7Cr17Mo12C13B9Y2 (at%) amorphous alloy coatings. The results indicate that increasing temperature accelerates the corrosion kinetics of the coating.

高铁酸钠的电化学合成及铁阳极钝化机理研究

open access: yesGongye shui chuli, 2022
以铁片为阳极、金属钛板为阴极,采用电化学氧化法合成高铁酸钠,研究了NaOH电解液浓度、制备温度和电流密度对高铁酸钠生成的影响及机理,并探析了高铁酸钠制备过程中铁阳极钝化的机理。结果表明,提高NaOH浓度和制备温度不仅有利于高铁酸钠的生成,同时也有利于提高电流效率;提高电流密度虽会增加高铁酸钠的生成量,但也会显著降低电流效率。综合考虑电流效率和制备成本,高铁酸钠的最佳制备条件为:NaOH浓度为14 mol/L、温度为45 ℃、电流密度为5 mA/cm2。在最佳制备参数下电解后,利用FESEM ...

Broad‐Spectral Response Lead Halide Perovskite Solar Cells Through Integration of Multifunctional Organic Bulk‐Heterojunction and Quantum‐Cutting Downconversion Materials

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Expanding near‐infrared (NIR) spectral response and utilizing ultraviolet (UV) photons are effective strategies for enhancing the power conversion efficiency (PCE) of lead halide perovskite solar cells (PSCs). However, the range of NIR spectral response extension and the utilization of UV light for devices are not enough, and the loss of ...
