Catalyst–support interaction plays a crucial role in improving the catalytic activity of oxygen evolution reaction(OER).Here we modulate the catalyst–support interaction in polyaniline-supported Ni_(3)Fe oxide(Ni_(3)Fe oxide/PANI)with a robust hetero-interface,which significantly improves oxygen evolution activities with an overpotential of 270 mV at 10 mA cm^(-2)and specific activity of 2.08 mA cm_(ECSA)^(-2)at overpotential of 300 mV,3.84-fold that of Ni_(3)Fe *** is revealed that the catalyst–support interaction between Ni_(3)Fe oxide and PANI support enhances the Ni–O covalency via the interfacial Ni–N bond,thus promoting the charge and mass transfer on Ni_(3)Fe *** the excellent activity and stability,rechargeable Zn-air batteries with optimum Ni_(3)Fe oxide/PANI are assembled,delivering a low charge voltage of 1.95 V to cycle for 400 h at 10 mA cm^(-2).The regulation of the effect of catalyst–support interaction on catalytic activity provides new possibilities for the future design of highly efficient OER catalysts.

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.

Bilateral bidirectional superior cavopulmonary shunt is more beneficial in medium and long term clinical outcomes than unilateral shunt

引用

Chinese Medical Journal 2009年第2期122卷 129-135页

作者： XU Yao-qiang liU Ying-long lu xiao-dong li Yong-qing YU Cun-tao Pediatric Cardiac Center Cardiovascular Institute and Fuwai Hospital Chinese Academy of Medical Sciences and Peking Union Medical College Beijing 100037 China

Background The present study was aimed to compare the effects of bilateral and unilateral bidirectional superior cavopulmonary shunt （b-BDG and u-BDG） on pulmonary artery growth and clinical outcomes. Methods The 51 subjects enrolled in this study were divided into two groups： those receiving b-BDG （n=21） and those receiving u-BDG （n=30）. Clinical records were reviewed retrospectively at a mean of 43.3 months after BDG procedures. Chi square and t-tests were performed to analyze the data. Results Left and right pulmonary artery diameters increased 27%-37% in both groups. The pulmonary artery index increased 37.2% after b-BDG and 27.0% after u-BDG, b-BDG patients experienced a significant decrease in mean hemoglobin concentration and hematocrit value, and a correlated change in postoperative diameter of left pulmonary artery （LPA） and pulmonary artery index （y=0.2719, x=-1.8278; R=0.564, P=-0.008）. The change ratio of hemoglobin and postoperative LPA were also correlated in b-BDG patients （y= -0.0522x ＋ 0.3539; R=-0.479, P=-0.028）. Only one b-BDG patient versus twelve u-BDG patients needed total cavopulmonary connections 31.8 months after BDG surgery （P=-0.0074）. Moreover, only one （4.8%） b-BDG patient but eight u-BDG patients （26.7%） developed pulmonary arteriovenous malformations. Conclusions b-BDG increases bilateral pulmonary blood flow and promotes growth of bilateral pulmonary arteries, with preferable physiological outcomes to u-BDG. Results may imply that subsequent Fontan repair may not always be needed. Chin Med J 2009; 122（2）： 129-135

随着生态旅游的流行与快速发展对生态旅游这个术语的概念也不断的增长扩散。由于缺乏对其内涵的科学认知和梳理,生态旅游概念的应用具有泛化的危险。不断涌现出的大量有关生态旅游的概念给学术研究和旅游管理带来了许多困惑。运用内容分析的方法对中外旅游文献近10～15a内有影响力的40个生态旅游概念进行了分析,提炼出生态旅游概念中最频繁出现的能代表其内涵的6个标准,它们是:以自然为基础、对保护的贡献、当地社区受益、环境教育、道德规范与责任和可持续性。通过对这些标准的识别,结合先前的生态旅游概念,本文对生态旅游的概念在操作层面上进行了重新架构,将生态旅游这一术语定义为:生态旅游是以可持续旅游和伦理道德规范原则为指导,在旅游过程中强调环境教育、影响管理和社区受益,并为其所依赖的环境保护做贡献的负责任的自然之旅。
