A kind of complex additive mainly containing Al, Mg, F, and O was prepared. The synthetical performances of the property-modified prebaked anodes containing additives were tested in laboratory. On the basis of ideal testing results obtained, a large number of industrial prebaked property-modified anodes are prepared in a large-scale aluminum company. Further more, they are all used in 160 kA prebaked anode aluminum electrolysis cells. The statistic result show that, compared with common anodes, the property-modified ones enhance current by 11.6 kg per ton aluminum averagely.

KINETIC AND APPliCATION: STUDIES ON THE REACTION SYSTEM OF OSMIUM(Ⅳ)-ARSENIC(Ⅲ)-CHLORATE

引用

Chinese Chemical Letters 1991年第8期2卷 641-644页

作者： Chen Zhen QIN xiao jin li Zhi liang JIANG Department of Chemistry Guangxi Normal UniversityGuilin 541004

The experiments have proved that Os(Ⅳ) has very strong catalytic effect on the chlorate oxidation of As(Ⅲ) in perchloric acid media, and As(Ⅲ) exhibits a sensitive single-sweep oscillopolarographic wave at-0.75 V vs. SCE. The kinetics of this catalytic reaction has been investigated by the initial rate procedure. The mechanism has been proposed. A new and highly sensitive catalytic reaction-oscillopolarographic method for the determination of ultratrace amounts of osmium has been described, based on the Os(Ⅳ) catalytic effect on the reaction. The linear range of 5.0×10^(-11)-4.4×10^(-9) mol/L and 6.0×10^(-9)-1.3×10^(-7) mol/L Os was obtained using the fixed-time procedure and the initial rate procedure, respectively. Osmium in refined ore was analysed by this method.

　　Many dihydropyrimidinones and their derivatives play an important role in medicine due to their therapeutic and pharmacological properties. [1] They have emerged as the integral backbones of several calcium channel blockers, antihypertensive agents, alpha-1α-antagonists. [2] Strategies for the synthesis of dihydropyrimidinone nucleus have varied from one-pot to multistep approaches. Although high yields can be achieved by the following complex multistep procedures, these methods lack the simplicity comparing with Biginelli protocol which firstly reported by Biginelli by one-pot condensation of aryl aldehyde, β-ketoesters and urea with catalytic acid in 1993, and these multistep methods suffer from low yields particularly for substituted aromatic aldehyde.……

针对船舶交通流时间序列的非线性和非平稳性特点,设计一种结合集合经验模态分解(ensemble empirical mode decomposition,EEMD)和差分进化算法优化BP神经网络(back propagation neural network optimized with differential evolution algorithm,DEBPNN)的船舶交通流组合预测模型(EEMD-DEBPNN).首先,利用EEMD算法降低船舶交通流时间序列的非平稳性;然后,对EEMD分解后获得的各非线性分量采用DEBPNN模型(先采用DE算法对BPNN的初始权值和阈值进行预寻优,再利用预寻优获得的初始权值和阈值训练BP神经网络得到最优的权值和阈值)进行预测;最后,再将各分量预测值进行叠加即得到最终预测结果.基于长江某港口航道船舶月交通流数据,将该组合模型与BPNN、DEBPNN模型进行实例对比分析.结果表明,EEMD-DEBPNN较DEBPNN、BPNN模型的预测精度更高.

Unlocking the stable interface in aqueous zinc-ion battery with multifunctional xylose-based electrolyte additives

引用

Journal of Energy Chemistry 2025年第1期100卷 770-778页

作者： xiaoqin li Jian Xiang Lu Qiu xiaohan Chen Yinkun Zhao Yujue Wang Qu Yue Taotao Gao Wenlong liu Dan xiao Zhaoyu jin Panpan li Institute for Advanced Study Chengdu University School of Mechanical Engineering Chengdu University College of Food and Biological Engineering Chengdu University Institute of Fundamental and Frontier Sciences University of Electronic Science and Technology of China College of Materials Science and Engineering Sichuan University

The growth of dendrites and the side reactions occurring at the Zn anode pose significant challenges to the commercialization of aqueous Zn-ion batteries（AZIBs）. These challenges arise from the inherent conflict between mass transfer and electrochemical kinetics. In this study, we propose the use of a multifunctional electrolyte additive based on the xylose（Xylo） molecule to address these issues by modulating the solvation structure and electrode/electrolyte interface, thereby stabilizing the Zn anode. The introduction of the additive alters the solvation structure, creating steric hindrance that impedes charge transfer and then reduces electrochemical kinetics. Furthermore, in-situ analyses demonstrate that the reconstructed electrode/electrolyte interface facilitates stable and rapid Zn2+ion migration and suppresses corrosion and hydrogen evolution reactions. As a result, symmetric cells incorporating the Xylo additive exhibit significantly enhanced reversibility during the Zn plating/stripping process, with an impressively long lifespan of up to 1986 h, compared to cells using pure ZnSO4electrolyte. When combined with a polyaniline cathode, the full cells demonstrate improved capacity and long-term cyclic stability. This work offers an effective direction for improving the stability of Zn anode via electrolyte design, as well as highperformance AZIBs.
