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, Volume 45, Issue 3, March 2026.
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

Design and Implementation of Public Resources Trading System for the Xinjiang Production and Construction Corps Based on .Net technology [PDF]

open access: yes, 2015
近几年,中央不断提出深化行政审批制度改革,随着这项工作的不断推进,也进一步推进了公共资源交易制度的改革,源头防腐和治理腐败亦成为形成规范统一的公共资源交易市场的最终目的。兵团现有14个师,176个团,公共资源交易中又存在资源不共享、监督不全面等问题。 兵团公共资源交易系统就是为了使交易全过程网络化、规范化、透明化运行而产生的。本文对兵团公共资源交易业务现状和需求进行分析,按照兵团党委办公厅、兵团办公厅对公共资源交易的高层次要求以及兵团信息中心对所提出的技术要求,系统基于.Net平台等先进技术,从性能 ...

Ionic‐Liquid‐Assisted Synthesis of NiTe/CoTe Heterostructure With Te Vacancies in N, P, and F Co‐Doped Hollow Carbon Nanorods for Efficient Alkaline Hydrogen Evolution and High‐Performance Flexible Supercapacitors

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Low conductivity, slow ion‐diffusion, and limited reactive sites are common problems in electrocatalysts and electrode materials. In this study, a complex NiTe–CoTe heterojunction with abundant Te vacancies embedded in N, P, and F co‐doped hollow carbon nanorods (NiTe1−x–CoTe1−x/NPFC) was fabricated via a simple ionic liquid‐assisted ...

ZnO压敏电阻的并联结构对通流能力的影响

open access: yesDianci bileiqi, 2015
为了提高电涌保护器中压敏电阻的耐电流冲击性能,生产上均采取压敏电阻的并联组合。在测试过程中发现,论文中的两种并联结构其8/20μs通流容量相差约20%。对并联组合后的压敏电阻劣化原因进行了分析,认为非对称并联结构的电流不均匀,其中一只压敏电阻承受的电流过大,导致性能迅速劣化、失效。通过加大电极片、连接片的宽度,降低阻抗,减小电流值的偏差,同时采用不同通流容量的压敏电阻进行配对并联,从而提高非对称并联结构的通流容量。

Systematic Study of Fermi‐Level Pinning at Crystalline Metal/GaN Interfaces: First‐Principles Calculations and Diode Characterization

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT The Schottky barrier height (SBH), which serves as a pivotal determinant of charge carrier injection efficiency in electronic devices, critically governs electrical behavior at metal/semiconductor interfaces. However, pronounced metal‐induced gap states at metal contact interfaces induce Fermi‐level pinning, which constrains the ...
