Stable and efficient single atom catalysts(SACs)are highly desirable yet challenging in catalyzing acidic oxygen evolution reaction(OER).Herein,we report a novel iridium single atom catalyst structure,with atomic Ir doped in tetragonal PdO matrix(IrSAs-PdO)via a lattice-confined *** optimized IrSAs-PdO-0.10 exhibited remarkable OER activity with an overpotential of 277 mV at 10 mA·cm^(-2) and long-term stability of 1000 h in 0.5 M H_(2)SO_(4).Furthermore,the turnover frequency attains 1.6 s^(-1) at an overpotential of 300 mV with a 24-fold increase in the intrinsic *** high activity originates from isolated iridium sites with low valence states and decreased Ir–O bonding covalency,and the excellent stability is a result of the effective confinement of iridium sites by Ir–O–Pd ***,we demonstrated for the first time that SACs have great potential in realizing ultralow loading of iridium(as low as microgram per square center meter level)in a practical water electrolyzer.

Degradation mechanisms and stabilization strategies of ruthenium-based catalysts for OER in the proton exchange membrane water electrolyzer

引用

Progress in Natural Science:Materials International 2024年第1期34卷 207-222页

作者： Ming Yang Hongxiang wu Zhaoping Shi yibo Wang Jiahao Yang Jing Ni Pengbo Wang Yuqing Cheng Ziang Wang Meiling Xiao Changpeng Liu Wei Xing Laboratory of Advanced Power Sources Changchun Institute of Applied Chemistry Chinese Academy of Sciences School of Applied Chemistry and Engineering University of Science and Technology of China Jilin Province Key Laboratory of Low Carbon Chemical Power Sources State Key Laboratory of Electroanalytical Chemistry Changchun Institute of Applied Chemistry Chinese Academy of Sciences

Designing economical oxygen evolution reaction(OER) electrocatalysts with high activity and long-term stability is essential to promote the scale-up applications of proton exchange membrane water electrolyzer(PEMWE) for hydrogen production. Ruthenium(Ru)-based materials with high intrinsic activity are hailed as the most promising catalysts, but still infeasible for practical application considering their long unresolved poor stability(only dozens of lifespan). Thus, tremendous efforts have been devoted to uncovering the degradation mechanisms and developing stabilization strategies for the Ru-based catalysts. In this review, starting from summarizing the fundamental understanding of deactivation mechanisms, a picture of the stability issue of Ru-based catalysts is proposed, which is followed by a detailed discussion on the recently developed strategies and progress made on enhancing durability. Finally, insights on the prospects for the future development of stable and practical Rubased OER catalysts are provided.

Comparative Analysis of Noise Margin between Pure SET-SET and Hybrid SET-PMOS Inverters

引用

Chinese Journal of Electronics 2024年

作者： Fan ZHANG Yi LIU yibo WANG Minghu wu Sheng HU Youli DONG Hubei Key Laboratory for High-Efficiency Utilization of Solar Energy and Operation Control of Energy Storage System Hubei University of Technology School of Electrical and Electronic Engineering Hubei University of Technology

Single-electron transistor（SET） is considered as one of the promising candidates for future electronic devices due to its advantages of low power consumption and high integration. The comparative analysis of SETbased inverters, especially the noise margin, is carried out. Pure SET-SET and hybrid SET with p type metal oxide semiconductor（SET-PMOS） inverters are designed for investigation. The effects of SET supply voltage, junction resistance and junction capacitance on noise tolerance and power consumption of inverters are studied. For hybrid SET-PMOS inverters, the noise margin for a logic high（NMH） is less than 60 mV under various conditions, which may become the bottleneck of its application. For pure SET-SET inverters, both NMH and the noise margin for a logic low（NML） could reach 300 mV at a supply voltage of 0.8 V. The minimum power consumption of pure SETSET and hybrid SET-PMOS inverters is 2.85 nW and 58 nW, respectively. The pure SET-SET inverters have greater noise tolerance and lower power consumption, which is more conducive to large-scale integration. When junction capacitance CJ= 0.0273 aF and junction resistance V, the NMH and NML are not significantly affected by the junction resistance and the noise margin fluctuates at 300mV.

作为技术与艺术相结合的产物,数字字体携带着文化基因与技术因子的双重因素,两者互相依存和影响。20世纪70年代以后,计算机技术开始普及并得到迅猛发展,西方的字体技术与桌面出版系统的诞生,促使西文数字字体设计进入新纪元。借助于技术的变革力量,字体排印设计与实践呈现出对技术与文化的双重映射的印记。它不但重组了字体设计表层组合、转换的形式,创造了围绕字体设计展开的存在环境和工作方式,而且还摆脱了人们思想的束缚,改变着人们的文化生活、精神需求和价值观念。尤其这一时期,哲学领域的后现代思潮深刻地影响着字体排印的发展,成为数字字体实践可以利用的"思想媒介"。字体设计师正是利用这种"媒介"创作出反映时代、社会及文化的设计作品。
