| 1 | Defects enriched hollow porous Co-N-doped carbons embedded with ultrafine CoFe/Co nanoparticles as bifunctional oxygen electrocatalyst for rechargeable flexible solid zinc-air batteries显示文摘The construction and design of highly efficient and inexpensive bifunctional oxygen electrocatalysts substitute for noble-metal-based catalysts is highly desirable for the development of rechargeable Zn-air battery(ZAB).In this work,a bifunctional oxygen electrocatalysts of based on ultrafine CoFe alloy(4-5 nm)dispersed in defects enriched hollow porous Co-N-doped carbons,made by annealing SiO2 coated zeolitic imidazolate framework-67(ZIF-67)encapsulated Fe ions.The hollow porous structure not only exposed the active sites inside ZIF-67,but also provided efficient charge and mass transfer.The strong synergetic coupling among high-density CoFe alloys and Co-N_(x) sites in Co,N-doped carbon species ensures high oxygen reduction reaction(ORR)and oxygen evolution reaction(OER)activity.First-principles simulations reveal that the synergistic promotion effect between CoFe alloy and Co-N site effectively reduced the formation energy of from O^(*)to OH^(*).The optimized CoFe-Co@PNC exhibits outstanding electrocatalytic stability and activity with the overpotential of only 320 mV for OER at 10 mA·cm^(−2) and the half-wave potential of 0.887 V for ORR,outperforming that of most recent reported bifunctional electrocatalysts.A rechargeable ZAB constructed with CoFe-Co@PNC as the air cathode displays long-term cyclability for over 200 h and high power density(152.8 mW·cm^(−2)).Flexible solid-state ZAB with our CoFe-Co@PNC as the air cathode possesses a high open circuit potential(OCP)up to 1.46 V as well as good bending flexibility.This universal structure design provides an attractive and instructive model for the application of nanomaterials derived from MOF in the field of sustainable flexible energy applications device. | Zhao Lei Yangyang Tan Zeyi Zhang Wei Wu Niancai Cheng Runzhe Chen Shichun Mu Xueliang Sun | 2021 | Nano Research2021，14，3： | 9 |

| 3 | Tuning the dual-active sites of ZIF-67 derived porous nanomaterials for boosting oxygen catalysis and rechargeable Zn-air batteries显示文摘The rational control of the active site of metal-organic frameworks(MOFs)derived nanomaterials is essential to build efficient bifunctional oxygen reduction/evolution reaction(ORR/OER)catalysts.Accordingly,through designing and constructing a Co_(3)O_(4)-Co heterostructure embedded in Co,N co-doped carbon polyhedra derived(Co_(3)O_(4)-Co@NC)from the in-situ compositions of ZIF-67 and cobalt nanocrystals synthesized by the strategy of in-situ NaBH4 reduction,the dual-active site(Co_(3)O_(4)-Co and Co-N_(x))is synchronously realized in a MOFs derived nanomaterials.The formed Co_(3)O_(4)-Co@NC shows excellent bifunctional electrocatalytic activity with ultra-small potential gap(ΔE=E_(j=10)(OER)–E_(1/2)(ORR))of 0.72 V,which surpasses the commercial Pt/C and RuO_(2) catalysts.The theory calculation results reveal that the excellent bifunctional electrocatalytic activity can be attributed to the charge redistribution of Co of Co-N_(x) induced by the synergistic effects of well-tuned active sites of Co_(3)O_(4)-Co nanoparticle and Co-N_(x),thus optimizing the rate-determining step of the desorption of O_(2)^(*)intermediate in ORR and OH^(*)intermediate in OER.The rechargeable Zn-air batteries with our bifunctional catalysts exhibit superior performance as well as high cycling stability.This simple-effective optimization strategy offers prospects for tuning the active site of MOF derived bifunctional catalyst in electrochemical energy devices. | Zeyi Zhang Yangyang Tan Tang Zeng Liyue Yu Runzhe Chen Niancai Cheng Shichun Mu Xueliang Sun | 2021 | Nano Research2021，14，7： | 3 |
| 4 | 287例盆腔及腹主动脉旁淋巴结清扫术与卵巢上皮性癌生存预后的临床分析(英文)显示文摘Objective: To evaluate the relationship between the pelvic and para-aortic lymphadenectomy and the prognosis of epithelial ovarian cancer. Methods: 287 patients suffering from primary epithelial ovarian cancer from 1995 to 2005 were analyzed retrospectively. Results: The 3-, 5-, 10-year survival with systematic lymphadenectomy (SL) were slightly higher than those without SL, but there were no statistically significance (P > 0.05). The 3-, 5-, 10-year survival of clinical stages without SL were lower than those with SL, but there were no significant difference either (P > 0.05). The 3-,5-, and 10-year survival rates with SL were higher than those without SL with no statistically differences (P > 0.05) among the subgroups such as absent, ≤ 2 cm and > 2 cm residual tumor. The survival rates of the groups without residual tumor and the group with ≤ 2 cm residual tumor were significantly higher than that of > 2 cm (P < 0.005). On multivariate analysis, patient staging (P = 0.01) and size of residual disease after primary cytoreductive surgery (P < 0.001 and = 0.002, respectively) retained prognostic significance. SL was not proved to be an independent prognostic factor (P = 0.69). Conclusion: Systematic pelvic and para-aortic lymphadenectomy can not improve and prolong the survival time significantly. | Xiaoyun Yang Minmin Hou Kaixuan Yang Hongjing Wang Zhilan Peng Zeyi Cao Mingrong Xi | 2007 | The Chinese-German Journal of Clinical Oncology2007，6，5： | 2 |

| 6 | A novel surrogate modeling strategy of the mechanical properties of 3D braided composites显示文摘In this paper,a surrogate-based modeling methodology is developed and presented to predict the elastic properties of three dimensional(3 D)four-directional braided composites.Using this approach,the prediction process becomes feasible with only a limited number of training points.The surrogate models constructed using Finite Element(FE)method and Diffuse Approximation,reduce the computational time and cost for preparing experimental samples.In the FE model,multiscale method is applied to couple the computations of elastic properties at microscale and mesoscale.Subsequently,a parametric study is performed to analyze the effects of the three design parameters on the elastic properties.Satisfactory results are obtained via the surrogatebased modeling predictions,which are compared with the experimental measurements.Moreover,the predictions obtained from surrogate models concur well with the FE predictions.This study orients a new direction for predicting the mechanical properties based on surrogate models which can effectively reduce the sample preparation cost and computational efforts. | Zeyi LIU Yuliang HOU Qiaoli ZHAO Cheng LI | 2020 | Chinese Journal of Aeronautics2020，33，10： | 2 |
| 7 | Process operation performance of PDMS membrane pervaporation coupled with fermentation for efficient bioethanol production显示文摘There would be strong product inhibition on ethanol fermentation process if ethanol is not removed in situ from broth. PDMS membrane pervaporation coupled with fermentation is a promising process for efficient bioethanol production since ethanol inhibition is relieved or eliminated. From the perspective of process operation, membrane separation performance, ethanol fermentation performance and the subsequent processing on membrane downstream are the three key issues. This review aims at contributing a comprehensive overview on the operation performance of the integrated process. The state-of-the-art of the three key issues related to the operation performance is focused. Finally, the tentative perspective on the possible future prospects of the integrated process is briefly presented. | Senqing Fan Jingyun Liu Xiaoyu Tang Wenguo Wang Zeyi Xiao Boya Qiu YuyangWang Shizhao Jian Yangmei Qin Yinan Wang | 2019 | Chinese Journal of Chemical Engineering2019，27，6： | 2 |

| 16 | A survey of federated learning for edge computing:Research problems and solutions显示文摘Federated Learning is a machine learning scheme in which a shared prediction model can be collaboratively learned by a number of distributed nodes using their locally stored data.It can provide better data privacy be-cause training data are not transmitted to a central server.Federated learning is well suited for edge computing applications and can leverage the the computation power of edge servers and the data collected on widely dis-persed edge devices.To build such an edge federated learning system,we need to tackle a number of technical challenges.In this survey,we provide a new perspective on the applications,development tools,communication efficiency,security&privacy,migration and scheduling in edge federated learning. | Qi Xia Winson Ye Zeyi Tao Jindi Wu Qun Li | 2021 | High-Confidence Computing2021，1，1： | 1 |
| 17 | The Solar Upper Transition Region Imager(SUTRI)Onboard the SATech-01 Satellite显示文摘The Solar Upper Transition Region Imager(SUTRI)onboard the Space Advanced Technology demonstration satellite(SATech-01),which was launched to a Sun-synchronous orbit at a height of~500 km in 2022 July,aims to test the on-orbit performance of our newly developed Sc/Si multi-layer reflecting mirror and the 2k×2k EUV CMOS imaging camera and to take full-disk solar images at the Ne VII 46.5 nm spectral line with a filter width of~3 nm.SUTRI employs a Ritchey-Chrétien optical system with an aperture of 18 cm.The on-orbit observations show that SUTRI images have a field of view of~416×416 and a moderate spatial resolution of~8″without an image stabilization system.The normal cadence of SUTRI images is 30 s and the solar observation time is about16 hr each day because the earth eclipse time accounts for about 1/3 of SATech-01's orbit period.Approximately15 GB data is acquired each day and made available online after processing.SUTRI images are valuable as the Ne VII 46.5 nm line is formed at a temperature regime of~0.5 MK in the solar atmosphere,which has rarely been sampled by existing solar imagers.SUTRI observations will establish connections between structures in the lower solar atmosphere and corona,and advance our understanding of various types of solar activity such as flares,filament eruptions,coronal jets and coronal mass ejections. | Xianyong Bai Hui Tian Yuanyong Deng Zhanshan Wang Jianfeng Yang Xiaofeng Zhang Yonghe Zhang Runze Qi Nange Wang Yang Gao Jun Yu Chunling He Zhengxiang Shen Lun Shen Song Guo Zhenyong Hou Kaifan Ji Xingzi Bi Wei Duan Xiao Yang Jiaben Lin Ziyao Hu Qian Song Zihao Yang Yajie Chen Weidong Qiao Wei Ge Fu Li Lei Jin Jiawei He Xiaobo Chen Xiaocheng Zhu Junwang He Qi Shi Liu Liu Jinsong Li Dongxiao Xu Rui Liu Taijie Li Zhenggong Feng Yamin Wang Chengcheng Fan Shuo Liu Sifan Guo Zheng Sun Yuchuan Wu Haiyu Li Qi Yang Yuyang Ye Weichen Gu Jiali Wu Zhe Zhang Yue Yu Zeyi Ye Pengfeng Sheng Yifan Wang Wenbin Li Qiushi Huang Zhong Zhang | 2023 | Research in Astronomy and Astrophysics2023，23，6： | 1 |
