| 3 | Enhanced N_(2)-to-NH_(3)conversion efficiency on Cu3P nanoribbon electrocatalyst显示文摘Ambient electroreduction of nitrogen(N_(2))is considered as a green and feasible approach for ammonia(NH_(3))synthesis,which urgently demands for efficient electrocatalyst.Morphology has close relationship with catalytic activity of heterogeneous catalysts.Nanoribbon is attractive nanostructure,which possesses the flexibility of one-dimensional nanomaterials,the large surface area of two-dimensional nanomaterials,and lateral size confinement effects.In this work,Cu_(3)P nanoribbon is proposed as a highly efficient electrocatalyst for N_(2)-to-NH_(3)conversion under benign conditions.When measured in N_(2)-saturated 0.1 M HCl,such Cu_(3)P nanoribbon achieves high performance with an excellent Faradaic efficiency as high as 37.8%and a large yield of 18.9μg·h^(−1)·mgcat.−1 at−0.2 V.It also demonstrates outstanding stability in long-term electrolysis test at least for 45 h. | Qian Liu Yiting Lin Shuang Gu Ziqiang Cheng Lisi Xie Shengjun Sun Longcheng Zhang Yongsong Luo Abdulmohsen Ali Alshehri Mohamed SHamdy Qingquan Kong Jiahong Wang Xuping Sun | 2022 | Nano Research2022，15，8： | 1 |

| 5 | A facile design for multifunctional AIEgen based on tetraaniline derivatives显示文摘Aniline oligomers have been widely used in many fields due to their excellent physicochemical properties. Owing to strong intermolecular interactions, their emission is always weakened or quenched when they are in high concentration or aggregated state, which greatly limits their fluorescent applications. Inspired by the concept of aggregation-induced emission(AIE), herein we introduced large steric groups onto the aniline oligomer to prevent the formation of packing structure. In particular, diphenyl vinyl group was bonded with oligomeric tetraaniline by a facile synthetic procedure with high yield. The obtained aniline oligomer derivative exhibited typical AIE features, which was also confirmed by density functional theoretical calculation. More importantly, this AIE oligomer was able to detect Fe^(3+) ions selectively and quantitatively. The fluorescence intensity decreased linearly along with the increment of Fe^(3+) concentration. Moreover, we demonstrated that this AIE oligomer could stain live bacteria, such as E. coli and S. aureus efficiently. All these results suggest that such a readily accessible and multifunctional tetraaniline derivative provides a new platform for the construction of fluorescent materials. | Beibei Liu Wei He Hao Lu Kun Wang Mingming Huang Ryan Tsz Kin Kwok Jacky Wing Yip Lam Longcheng Gao Jiping Yang Benzhong Tang | 2019 | Science China Chemistry2019，62，6： | 1 |

| 9 | Stretchable and Superhydrophilic Polyaniline/Halloysite Decorated Nanofiber Composite Evaporator for High Efficiency Seawater Desalination显示文摘Here,authors report on composition of a stretchable,mechanically durable and superhydrophilic polyaniline(PANI)/hal-loysite nanotubes(HNTs)decorated PU nanofiber(PANI/HNTs@PU).The polymer nanofibers are placed as the core and PANI/HNTs makes the shell section.The PANI/HNTs creates a membrane with outstanding light absorption and photo-thermal conversion performance.The strong solar absorption capability and superhydrophilicity of the PANI/HNTs@PU remain almost unchanged during stretching,abrasion,and ultrasonic washing tests,exhibiting superior surface stability and durability.When the PANI/HNTs@PU is used for the interfacial evaporation,the evaporation rate and efficiency reach as high as 1.61 kg m^(-2) h^(-1) and 94.7%,respectively.No salt precipitation is observed on the solar absorber surface even under a high salinity or during the long term or cyclic evaporation test.Furthermore,the excellent interfacial evaporation function is maintained when the nanofiber composite is mechanically stretched.The PANI/HNTs@PU based evaporation device shows promising applications in high performance solar desalination. | Jiang Han Wenqian Xing Jun Yan Jing Wen Yuntao Liu Yuqing Wang Zefeng Wu Longcheng Tang Jiefeng Gao | 2022 | Advanced Fiber Materials2022，4，5： | 1 |
| 10 | Electron-ion collider in China显示文摘Lepton scattering is an established ideal tool for studying inner structure of small particles such as nucleons as well as nuclei.As a future high energy nuclear physics project,an Electron-ion collider in China(EicC)has been proposed.It will be constructed based on an upgraded heavy-ion accelerator,High Intensity heavy-ion Accelerator Facility(HIAF)which is currently under construction,together with a new electron ring.The proposed collider will provide highly polarized electrons(with a po-larization of 80%)and protons(with a polarization of 70%)with variable center of mass energies from 15 to 20 GeV and the luminosity of(2–3)×1033 cm^(−2)·s^(−1).Polarized deuterons and Helium-3,as well as unpolarized ion beams from Carbon to Uranium,will be also available at the EicC.The main foci of the EicC will be precision measurements of the structure of the nucleon in the sea quark region,including 3D tomography of nucleon;the partonic structure of nuclei and the parton interaction with the nuclear environment;the exotic states,especially those with heavy flavor quark contents.In addition,issues fundamental to understanding the origin of mass could be addressed by measurements of heavy quarkonia near-threshold production at the EicC.In order to achieve the above-mentioned physics goals,a hermetical detector system will be constructed with cutting-edge technologies.This document is the result of collective contributions and valuable inputs from experts across the globe.The EicC physics program complements the ongoing scientific programs at the Jefferson Laboratory and the future EIC project in the United States.The success of this project will also advance both nuclear and particle physics as well as accelerator and detector technology in China. | Daniele PAnderle Valerio Bertone Xu Cao Lei Chang Ningbo Chang Gu Chen Xurong Chen Zhuojun Chen Zhufang Cui Lingyun Dai Weitian Deng Minghui Ding Xu Feng Chang Gong Longcheng Gui Feng-Kun Guo Chengdong Han Jun He Tie-Jiun Hou Hongxia Huang Yin Huang KrešImir KumeričKi LPKaptari Demin Li Hengne Li Minxiang Li Xueqian Li Yutie Liang Zuotang Liang Chen Liu Chuan Liu Guoming Liu Jie Liu Liuming Liu Xiang Liu Tianbo Liu Xiaofeng Luo Zhun Lyu Boqiang Ma Fu Ma Jianping Ma Yugang Ma Lijun Mao Cédric Mezrag HervéMoutarde Jialun Ping Sixue Qin Hang Ren Craig DRoberts Juan Rojo Guodong Shen Chao Shi Qintao Song Hao Sun PawełSznajder Enke Wang Fan Wang Qian Wang Rong Wang Ruiru Wang Taofeng Wang Wei Wang Xiaoyu Wang Xiaoyun Wang Jiajun Wu Xinggang Wu Lei Xia Bowen Xiao Guoqing Xiao Ju-Jun Xie Yaping Xie Hongxi Xing Hushan Xu Nu Xu Shusheng Xu Mengshi Yan Wenbiao Yan Wencheng Yan Xinhu Yan Jiancheng Yang Yi-Bo Yang Zhi Yang Deliang Yao Zhihong Ye Peilin Yin C-PYuan Wenlong Zhan Jianhui Zhang Jinlong Zhang Pengming Zhang Yifei Zhang Chao-Hsi Chang Zhenyu Zhang Hongwei Zhao Kuang-Ta Chao Qiang Zhao Yuxiang Zhao Zhengguo Zhao Liang Zheng Jian Zhou Xiang Zhou Xiaorong Zhou Bingsong Zou Liping Zou | 2021 | Frontiers of physics2021，16，6： | 1 |
| 11 | Exceptionally flame-retardant flexible polyurethane foam composites:synergistic effect of the silicone resin/graphene oxide coating显示文摘A facile strategy was developed to fabricate flexible polyurethane(PU)foam composites with exceptional flame retardancy.The approach involves the incorporation of graphene oxide(GO)into a silicone resin(SiR)solution,which is then deposited onto a PU foam surface via the dip-coating technique and cured.Fourier-transform infrared spectroscopy,scanning electron microscopy,and Raman spectroscopy measurements demonstrated that the SiR and GO were successfully coated onto the PU skeleton and the intrinsic porous structure of the PU foam remained intact.The effects of SiR and GO on the mechanical and thermal stability and flame retardancy of PU composites were evaluated through compression tests,thermogravimetric analysis,vertical combustion tests,and the limiting oxygen index.The measurement results revealed that the composites(PU@SiR-GO)showed superior flame retardancy and thermal and mechanical stability compared to pristine PU or PU coated with SiR alone.The mechanical and thermal stability and the flame-retardant properties of the PU composites were enhanced significantly with increasing GO content.Based on the composition,microstructure,and surface morphology of PU@SiR-GO composites before and after combustion tests,a possible flame-retardance mechanism is proposed.This work provides a simple and effective strategy for fabricating flame retardant composites with improved mechanical performance. | Qian Wu Jincheng Zhang Shengpeng Wang Bajin Chen Yijun Feng Yongbing Pei Yue Yan Longcheng Tang Huayu Qiu Lianbin Wu | 2021 | Frontiers of Chemical Science and Engineering2021，15，4： | 1 |
