Rapid Fabrication of Electrodes for Symmetrical Solid Oxide Cells by Extreme Heat Treatment

Energy & Environmental Materials 2024年第05期7卷 353-360页

作者： Weiwei Fan Zhu sun Manxi Wang Manxian Li Yuming Chen Key Laboratory of Energy Thermal Conversion and Control of Ministry of Education School of Energy and Environment Southeast University department of Nuclear Science and Engineering Massachusetts Institute of Technology Cambridge School of Materials Science and Engineering Shanghai Jiao Tong University Zhangjiang Institute for Advanced Study (ZIAS) Shanghai Jiao Tong University College of Environmental Science and Engineering and College of physics and Energy Fujian Normal University

Symmetrical solid oxide cells （SSOCs） are very useful for energy generation and conversion. To fabricate the electrode of SSOC, it is very time-consuming to use the conventional approach. In this work, we design and develop a novel method, extreme heat treatment （EHT）, to rapidly fabricate electrodes for SSOC. We show that by using the EHT method, the electrode can be fabricated in seconds （the fastest method to date）, benefiting from enhanced reaction kinetics. The EHT-fabricated electrode presents a porous structure and good adhesion with the electrolyte. In contrast, tens of hours are needed to prepare the electrode by the conventional approach, and the prepared electrode exhibits a dense structure with a larger particle size due to the lengthy treatment. The EHT-fabricated electrode shows desirable electrochemical performance. Moreover, we show that the electrocatalytic activity of the perovskite electrode can be tuned by the vigorous approach of fast exsolution,deriving from the increased active sites for enhancing the electrochemical reactions. At 900℃, a promising peak power density of 966mWcm-2is reached. Our work exploits a new territory to fabricate and develop advanced electrodes for SSOCs in a rapid and high-throughput manner.

Superconductivity and superfluidity as universal emergent phenomena

Frontiers of physics 2015年第4期10卷 67-72页

作者： Mike Guidry yang sun department of physics and Astronomy University of Tennessee Knoxville Tennessee 37996 USA department of physics and Astronomy Shanghai Jiao Tong University Shanghai 200240 China IFSA Collaborative Innovation Center Shanghai Jiao Tong University Shanghai 200240 China State Key Laboratory of Theoretical physics Institute of Theoretical Physics Chinese Academy of Sciences Beijing 100190 China

Superconductivity （SC） or superfluidity （SF） is observed across a remarkably broad range of fermionic systems： in BCS, cuprate, iron-based, organic, and heavy-fermion superconductors, and in superfiuid helium-3 in condensed matter; in a variety of SC/SF phenomena in low-energy nuclear physics; in ultracold, trapped atomic gases; and in various exotic possibilities in neutron stars. The range of physical conditions and differences in microscopic physics defy all attempts to unify this behavior in any conventional picture. Here we propose a unification through the shared symmetry properties of the emergent condensed states, with microscopic differences absorbed into parameters. This, in turn, forces a rethinking of specific occurrences of SC/SF such as high-To SC in cuprates, which becomes far less mysterious when seen as part of a continuum of behavior shared by a variety of other systems.

On the structure of isomeric state in neutron-rich 108Zr: A projected shell model analysis

引用

Science china(physics,Mechanics & Astronomy) 2015年第11期58卷 92-98页

作者： LIU YanXin YU ShaoYing sun yang School of Science Huzhou University department of physics and Astronomy Shanghai Jiao Tong University IFSA Collaborative Innovation Center Shanghai Jiao Tong University State Key Laboratory of Theoretical physics Institute of Theoretical Physics Chinese Academy of Sciences

Inspired by the recent experimental identification of the new isomer with a half-life of （620±150） ns in the very neutron-rich nucleus 180SZr, we apply the projected shell model with axially-deformed bases to discuss possible shapes near the ground state and the nature of the isomer. The structure of the new isomer is investigated by restricting the calculation to prolate and oblate shapes. It is shown that the isomer can be understood as a K-isomer. Meanwhile, the calculation predicts more low-lying high-K configurations, which may be confirmed by future experiments,
