Highly Stable Aqueous Zinc Anodes Enabled by Synergistic Modulation of Interface and Solvation Structures

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT The stability of aqueous Zn2+ batteries is severely hindered by parasitic reactions at the Zn anode/electrolyte interface. Herein, itaconic acid (IA) is introduced as an effective electrolyte additive to achieve a highly stable zinc anode. Remarkably, IA concurrently modulates both the zinc anode/electrolyte interfacial structure and the Zn2 ...

The Optimization and Application of Indicator System of Liquidity Risk Management in Security Company [PDF]

open access: yes, 2016
随着证券行业创新业务快速发展,资本消耗型业务增长迅速,行业平均杠杆率快速提升,加之表外业务如担保、流动性支持承诺的履行导致证券公司流动性需求快速增加。证券公司融资主要通过向股东融资、发债、银行授信借款等渠道,稳定的、可用于解决流动性风险的融资手段有限。证券公司的风险管理水平有待提升,经营实践中短期负债匹配长期资产,资产负债结构失衡等问题时有发生。上述原因的综合作用导致证券公司流动性风险隐患增加,流动性风险逐步显现。 将流动性风险管理定位于满足监管要求已经难以适应发展的需求,证券公司必须进行主动性管理 ...

基于多层降维与FOA优化的接地网腐蚀故障诊断

open access: yesDianci bileiqi, 2016
针对变电站接地网腐蚀故障的精准定位与诊断问题,将果蝇优化算法运算速度快、全局收敛效果好的优点与电阻腐蚀倍数优化相结合,提出基于多层降维与果蝇优化的接地网腐蚀故障诊断方法。该方法以电压法与电阻法作为诊断机理,以果蝇优化算法作最优解全局搜索,结合多层降维解决接地网支路个数多的问题,降低优化复杂度,提高优化速度。以60条支路、36个节点的变电站接地网为例进行方法检验对比,结果表明,以果蝇优化算法为基础的电压法和电阻法均能取得较好的腐蚀故障诊断效果,电阻法的平均诊断误差略低于电压法,诊断效果较好,但时间代价更大。

Study on the On-line Photochemical Derivatization-Fluorescence Determination in HPLC and the Mechanism Investigation [PDF]

open access: yes, 2010
光化学衍生(photochemicalderivatization,PCD)分析法是基于光化学反应而建立的一类分析方法。它以其独特的衍生方式与传统的荧光、化学发光、紫外-可见、电化学等检测方法相结合,提高了原有方法的灵敏度与选择性,极大地拓展了传统检测方法的应用范围,在药物、复杂生物样品、环境样品分析测定等方面得到广泛应用。然而,已报道的光化学衍生方法中的光化学衍生装置比较简易,难于满足液相色谱柱后在线衍生对多种组分同时测定的需要;另一方面,大多分析工作者主要是从“表面”去优化光化学衍生的条件 ...
