| 1 | Intrusions of Kuroshio and Shelf Waters on Northern Slope of South China Sea in Summer 2015显示文摘The northern slope region of the South China Sea(SCS) is a biological hot spot characterized by high primary productivity and biomasses transported by cross-shelf currents, which support the spawning and growth of commercially and ecologically important fish species. To understand the physical and biogeochemical processes that promote the high primary production of this region, we conducted a cruise from June 10 and July 2, 2015. In this study, we used fuzzy cluster analysis and optimum multiparameter analysis methods to analyze the hydrographic data collected during the cruise to determine the compositions of the upper 55-m water masses on the SCS northern slope and thereby elucidate the cross-slope transport of shelf water(SHW) and the intrusions of Kuroshio water(KW). We also analyzed the geostrophic currents derived from acoustic Doppler current profiler measurements and satellite data. The results reveal the surface waters on the northern slope of the SCS to be primarily composed of waters originating from South China Sea water(SCSW), KW, and SHW. The SCSW dominated a majority of the study region at percentages ranging between 60% and 100%. We found a strong cross-slope current with speeds greater than 50 cms^(-1) to have carried SHW into and through the surveyed slope area, and KW to have intruded onto the slope via mesoscale eddies, thereby dominating the southwestern section of the study area. | LI Denghui ZHOU Meng ZHANG Zhaoru ZHONG Yisen ZHU Yiwu YANG Chenghao XU Mingquan XU Dongfeng HU Ziyuan | 2018 | Journal of Ocean University of China2018，17，3： | 2 |

| 3 | BiO_(2-x)Nanosheets with Surface Electron Localizations for Efficient Electrocatalytic CO_(2)Reduction to Formate显示文摘To enhance the activity and selectivity of electrocatalytic CO_(2)reduction to formate is of great importance from both environmental and economical viewpoints.Herein,the BiO_(2-x)nanosheets with surface electron localizations were constructed and utilized for the efficient CO_(2)-to-formate conversion.The formate Faraday efficiency reaches 99.1%with current density of 12 mA cm^(−2)at^(−1).1 V versus the reversible hydrogen electrode(RHE)in an H-type cell while those in the flow cell are 91.3%and 319 mA cm^(−2)at^(−1).0 V versus RHE,respectively.Theoretical calculations indicate that the electron localization presenting in the BiO_(2-x)nanosheet favors OCHO*intermediate stabilization and suppresses H*intermediate adsorption,thus improving the CO_(2)-to-formate efficiency.The BiO_(2-x)electrocatalyst is nondopant,easily prepared,low-cost,highly active and selective for CO_(2)RR to formate,which has demonstrated potential for application in the Zn-CO_(2)battery.The maximum power density can reach 2.33 mW cm^(−2),and the charge/discharge cycling stability is>100 h(300 cycles)at 4.5 mA cm^(−2). | Zhonghao Tan Jianling Zhang Yisen Yang Yufei Sha Ran Duan Jiajun Zhong Buxing Han Jingyang Hu Yingzhe Zhao | 2023 | CCS Chemistry2023，5，1： | 0 |
| 4 | Mesoporous Cu_(3−x)Zn_(x)(BTC)_(2)nanocubes synthesized in deep eutectic solvent and their catalytic performances显示文摘To develop high-performance metal-organic frameworks(MOFs)for catalysis is of great importance.Here,we synthesized the mesoporous Cu_(3−x)Zn_(x)(BTC)_(2)(BTC=benzene-1,3,5-tricarboxylate)nanocubes in a deep eutectic solvent of ZnCl_(2)/ethylene glycol solution.The route can proceed at room temperature and the reaction time needed is shortened to be 30 min,which is superior to the conventional solvothermal route that usually needs high temperature and long reaction time.The formation mechanism of the mesoporous Cu_(3−x)Zn_(x)(BTC)_(2)nanocubes in deep eutectic solvent(DES)was investigated by in situ synchrotron X-ray diffraction/small angle X-ray scattering/X-ray absorption fine structure conjunction technique.The mesoporous Cu_(3−x)Zn_(x)(BTC)_(2)nanocubes exhibit high catalytic activity and reusability for cyanosilylation reaction of benzaldehyde and aerobic oxidation reaction of benzylic alcohol. | Jingyang Hu Jianling Zhang Xiuniang Tan Xiuyan Cheng Zhuizhui Su Lixiong Qian Mingzhao Xu Yufei Sha Yanyue Wang Yisen Yang Yunpeng Liu Guang Mo Xueqing Xing Zhonghua Wu | 2023 | Nano Research2023，16，3： | 0 |
