| 1 | Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event. | TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou | 2018 | Science China(Physics,Mechanics & Astronomy)2018，61，3： | 12 |
| 2 | The Low Energy X-ray telescope (LE) onboard the Insight-HXMT astronomy satellite显示文摘The Low Energy X-ray telescope(LE) is one of the three main instruments of the Insight-Hard X-ray Modulation Telescope(Insight-HXMT). It is equipped with Swept Charge Device(SCD) sensor arrays with a total geometrical area of 384 cm^2 and an energy band from 0.7 to 13 ke V. In order to evaluate the particle induced X-ray background and the cosmic X-ray background simultaneously, LE adopts collimators to define four types of Field Of Views(FOVs), i.e., 1.6°×6°, 4°×6°, 50°-60°×2°-6 oand the blocked ones which block the X-ray by an aluminum cover. LE is constituted of three detector boxes(LEDs) and an electric control box(LEB) and achieves a good energy resolution of 140 e V@5.9 ke V, an excellent time resolution of 0.98 ms, as well as an extremely low pileup(<1%@18000 cts/s). Detailed performance tests and calibration on the ground have been performed,including energy-channel relation, energy response, detection efficiency and time response. | Yong Chen WeiWei Cui Wei Li Juan Wang YuPeng Xu FangJun Lul YuSa Wang TianXiang Chen DaWei Han Wei Hu Yi Zhang Jia Huo YanJi Yang MaoShun Li Bo Lu ZiLiang Zhang TiPei Li ShuangNan Zhang ShaoLin Xiong Shu Zhang RongFeng Xue XiaoFan Zhao Yue Zhu YuXuan Zhu HongWei Liu YiJung Yang Fan Zhang | 2020 | Science China(Physics,Mechanics & Astronomy)2020，63，4： | 8 |
| 3 | Guiding T lymphopoiesis from pluripotent stem cells by defined transcription factors显示文摘Achievement of immunocompetent and therapeutic T lymphopoiesis from pluripotent stem cells(PSCs)is a central aim in T cell regenerative medicine.To date,preferentially reconstituting T lymphopoiesis in vivo from PSCs remains a practical challenge.Here we documented that synergistic and transient expression of Runx1 and Hoxa9 restricted in the time window of endothelial-to-hematopoietic transition and hematopoietic maturation stages in a PSC differentiation scheme(iR9-PSC)in vitro induced preferential generation of engraftable hematopoietic progenitors capable of homing to thymus and developing into mature T cells in primary and secondary immunodeficient recipients.Single-cell transcriptome and functional analyses illustrated the cellular trajectory of T lineage induction from PSCs,unveiling the T-lineage specification determined at as early as hemogenic endothelial cell stage and identifying the bona fide pre-thymic progenitors.The induced T cells distributed normally in central and peripheral lymphoid organs and exhibited abundant TCRαβrepertoire.The regenerative T lymphopoiesis restored immune surveillance in immunodeficient mice.Furthermore,gene-edited iR9-PSCs produced tumor-specific T cells in vivo that effectively eradicated tumor cells.This study provides insight into universal generation of functional and therapeutic T cells from the unlimited and editable PSC source. | Rongqun Guo Fangxiao Hu Qitong Weng Cui Lv Hongling Wu Lijuan Liu Zongcheng Li Yang Zeng Zhijie Bai Mengyun Zhang Yuting Liu Xiaofei Liu Chengxiang Xia Tongjie Wang Peiqing Zhou Kaitao Wang Yong Dong Yuxuan Luo Xiangzhong Zhang Yuxian Guan Yang Geng Juan Du Yangqiu Li Yu Lan Jiekai Chen Bing Liu Jinyong Wang | 2020 | Cell Research2020，30，1： | 7 |

| 5 | Nitrated and parent PAHs in the surface water of Lake Taihu,China:Occurrence,distribution,source,and human health risk assessment显示文摘Nitrated polycyclic aromatic hydrocarbons(NPAHs)have toxic potentials that are higher than those of their corresponding parent polycyclic aromatic hydrocarbons(PAHs)and thus have received increasing attention in recent years.In this study,the occurrence,distribution,source,and human health risk assessment of 15 NPAHs and 16 PAHs were investigated in the surface water from 20 sampling sites of Lake Taihu during the dry,normal,and flood seasons of 2018.The PAH concentrations ranged from 255 to 7298 ng/L and the NPAH concentrations ranged from not-detected(ND)to 212 ng/L.Among the target analytes,2-nitrofluorene(2-n Flu)was the predominant NPAH,with a detection frequency ranging from 85%to 90%and a maximum concentration of 56.2 ng/L.The three-ringed and four-ringed NPAHs and PAHs comprised the majority of the detected compounds.In terms of seasonal variation,the highest levels of the NPAHs and PAHs were in the dry season and flood season,respectively.Diagnostic ratio analysis indicated that the prime source of NPAHs was direct combustion,whereas in the case of PAHs the contribution was predominantly from a mixed pattern including pollution from unburned petroleum and petroleum combustion.The human health risk of NPAHs and PAHs was evaluated using a lifetime carcinogenic risk assessment model.The carcinogenic risk level of the targets ranged from 2.09×10^(-7)to 5.75×10^(-5)and some surface water samples posed a potential health risk. | Jijie Kong Yuxuan Dai Mengshu Han Huan He Jiapeng Hu Junyi Zhang Junzhe Shi Qiming Xian Shaogui Yang Cheng Sun | 2021 | Journal of Environmental Sciences2021，33，4： | 6 |
| 6 | The landscape of aging显示文摘Aging is characterized by a progressive deterioration of physiological integrity,leading to impaired functional ability and ultimately increased susceptibility to death.It is a major risk factor for chronic human diseases,including cardiovascular disease,diabetes,neurological degeneration,and cancer.Therefore,the growing emphasis on “healthy aging” raises a series of important questions in life and social sciences.In recent years,there has been unprecedented progress in aging research,particularly the discovery that the rate of aging is at least partly controlled by evolutionarily conserved genetic pathways and biological processes.In an attempt to bring full-fledged understanding to both the aging process and age-associated diseases,we review the descriptive,conceptual,and interventive aspects of the landscape of aging composed of a number of layers at the cellular,tissue,organ,organ system,and organismal levels. | Yusheng Cai Wei Song Jiaming Li Ying Jing Chuqian Liang Liyuan Zhang Xia Zhang Wenhui Zhang Beibei Liu Yongpan An Jingyi Li Baixue Tang Siyu Pei Xueying Wu Yuxuan Liu Cheng-Le Zhuang Yilin Ying Xuefeng Dou Yu Chen Fu-Hui Xiao Dingfeng Li Ruici Yang Ya Zhao Yang Wang Lihui Wang Yujing Li Shuai Ma Si Wang Xiaoyuan Song Jie Ren Liang Zhang Jun Wang Weiqi Zhang Zhengwei Xie Jing Qu Jianwei Wang Yichuan Xiao Ye Tian Gelin Wang Ping Hu Jing Ye Yu Sun Zhiyong Mao Qing-Peng Kong Qiang Liu Weiguo Zou Xiao-Li Tian Zhi-Xiong Xiao Yong Liu Jun-Ping Liu Moshi Song Jing-Dong J.Han Guang-Hui Liu | 2022 | Science China(Life Sciences)2022，65，12： | 4 |

| 8 | Catalytic alkane dehydrogenations显示文摘Olefins find widespread applications in the synthesis of polyolefins and fine chemicals. With an increasing demand for olefins, the technologies for alkane dehydrogenation have drawn much attention. Several types of heterogeneous catalysts have found applications in industry for the dehydrogenation of light alkanes, mainly ethane, propane, and butane. In the past three decades, a number of transition-metal complexes,particularly pincer-ligated iridium complexes, have been developed as the homogeneous catalysts for alkane dehydrogenations. The homogeneous catalyst systems operate under much milder conditions compared with the heterogeneous systems, and some systems exhibit good activity and high regioselectivity in dehydrogenation of alkanes longer than butane. | Yuxuan Zhang Wubing Yao Huaquan Fang Aiguo Hu Zheng Huang | 2015 | Science Bulletin2015，60，15： | 4 |
| 9 | History,progress and future challenges of artificial blood vessels:a narrative review显示文摘Cardiovascular disease serves as the leading cause of death worldwide,with stenosis,occlusion,or severe dysfunction of blood vessels being its pathophysiological mechanism.Vascular replacement is the preferred surgical option for treating obstructed vascular structures.Due to the limited availability of healthy autologous vessels as well as the incidence of postoperative complications,there is an increasing demand for artificial blood vessels.From synthetic to natural,or a mixture of these components,numerous materials have been used to prepare artificial vascular grafts.Although synthetic grafts are more appropriate for use in medium to large-diameter vessels,they fail when replacing small-diameter vessels.Tissue-engineered vascular grafts are very likely to be an ideal alternative to autologous grafts in small-diameter vessels and are worthy of further investigation.However,a multitude of problems remain that must be resolved before they can be used in biomedical applications.Accordingly,this review attempts to describe these problems and provide a discussion of the generation of artificial blood vessels.In addition,we deliberate on current state-of-the-art technologies for creating artificial blood vessels,including advances in materials,fabrication techniques,various methods of surface modification,as well as preclinical and clinical applications.Furthermore,the evaluation of grafts both in vivo and in vitro,mechanical properties,challenges,and directions for further research are also discussed. | Ke Hu Yuxuan Li Zunxiang Ke Hongjun Yang Chanjun Lu Yiqing Li Yi Guo Weici Wang | 2022 | Biomaterials Translational2022，3，1： | 3 |

| 11 | Research on error compensation of robot based on multi-hole measurement technology and particle swarm optimization显示文摘Robot error compensation is a technique for enhancing the positioning accuracy of the system. This paper presented an error measuring technique for serial robots based on the multi-hole measuring method, combined with the intelligent particle swarm optimisation(PSO) to obtain the optimal solution of the robot’s error compensation values, thereby improving the positioning accuracy of the robot. In the experiment, the robot error was measured using self-made multi-hole measuring plates and probes, and the experimental data were combined with PSO for the error comprehensive analysis. The results showed that on this type of serial robot, the multi-hole measuring method and PSO algorithm had obvious error compensation effects, which effectively improved the positioning accuracy of the robot, with the error reduced by 35% after compensation. | Wang Xianlun Sun Yuxuan Wang Dong Hu Xiaowei | 2021 | The Journal of China Universities of Posts and Telecommunications2021，28，4： | 1 |
| 12 | Remarkably enhanced piezo-photocatalytic performance in BaTiO_(3)/CuO heterostructures for organic pollutant degradation显示文摘Introducing polarization field of piezoelectric materials is an effective strategy to improve photocatalytic performance.In this study,a new type of BaTiO_(3)/CuO heterostructure catalyst was designed and synthesized to achieve high piezo-photocatalytic activity through the synergy of heterojunction and piezoelectric effect.The BaTiO_(3)/CuO heterostructure shows a significantly enhanced piezo-photocatalytic degradation efficiency of organic pollutants compared with the individual BaTiO_(3) nanowires(NWs)and CuO nanoparticles(NPs).Under the co-excitation of ultrasonic vibration and ultraviolet radiation,the optimal degradation reaction rate constant k of polarized BaTiO_(3)/CuO heterostructure on methyl orange(MO)dye can reach 0.05 min^(−1),which is 6.1 times of photocatalytic rate and 7 times of piezocatalytic rate.The BaTiO_(3)/CuO heterostructure with remarkable piezo-photocatalytic behavior provides a promising strategy for the development of high-efficiency catalysts for wastewater purification,and it also helps understand the coupling mechanism between piezoelectric effect and photocatalysis. | Chenye YU Mengxi TAN Chengdong TAO Yuxuan HU Chuanbao LIU Huimin MENG Yanjing SU Lijie QIAO Yang BAI | 2022 | Journal of Advanced Ceramics2022，11，3： | 1 |

| 14 | Effect of nano-TiC dopant size on magnetic properties and corrosion resistance of hot-deformed NdFeB显示文摘Effects of dopant size on the magnetic properties and corrosion behavior of hot-deformed NdFeB with the intergranular additions of nano-TiC were investigated using X-ray diffraction(XRD),X-ray photoelectron spectrometer(XPS),scanning electron microscopy(SEM),electrochemical and magnetic measurement technologies.Additions of 50 nm-TiC,unlike 30 nm- and 40 nm-TiC,are found to increase the magnetic energy product and comprehensive magnetic properties,due in main to the improvement of magnet orientation by more strip-shaped Nd-rich phases.Nano-TiC dopants especially with a size of40 nm can increase the electrochemical corrosion resistance of magnets.It is attributed to the hindrance of additives on the reaction channel formation and their barrier effect on the oxidations of Nd and Fe.For 40 nm-TiC doped magnet,the charge transfer resistance in electric double layer structure reaches 15000 Ω·cm^(2) that is one order of magnitude higher than other cases,which is responsible for the lowe st corrosion current density and accordingly the best anti-corrosion properties. | Xiaoqiang Li Jian Li Kai Xu Zhiwei Wang Yu Bian Yuxuan Shao Chengchao Hu Junjie Ni | 2022 | Journal of Rare Earths2022，40，6： | 1 |
| 15 | Controlled growth of two-dimensional InAs single crystals via van der Waals epitaxy显示文摘Two-dimensional(2D)indium arsenide(InAs)is promising for future electronic and optoelectronic applications such as highperformance nanoscale transistors,flexible and wearable devices,and high-sensitivity broadband photodetectors,and is advantageous for its heterogeneous integration with Si-based electronics.However,the synthesis of 2D InAs single crystals is challenging because of the nonlayered structure.Here we report the van der Waals epitaxy of 2D InAs single crystals,with their thickness down to 4.8 nm,and their lateral sizes up to~37μm.The as-grown InAs flakes have high crystalline quality and are homogenous.The thickness can be tuned by growth time and temperature.Moreover,we explore the thickness-dependent optical properties of InAs flakes.Transports measurement reveals that 2D InAs possesses high conductivity and high carrier mobility.Our work introduces InAs to 2D materials family and paves the way for applying 2D InAs in high-performance electronics and optoelectronics. | Jiuxiang Dai Teng Yang Zhitong Jin Yunlei Zhong Xianyu Hu Jingyi Zou Weigao Xu Tao Li Yuxuan Lin Xu Zhang Lin Zhou | 2022 | Nano Research2022，15，11： | 1 |

| 17 | Triboelectric nanogenerators with a constant inherent capacitance design显示文摘Triboelectric nanogenerators(TENGs)utilize the phenomena of contact electrification and electrostatic induction to harvest mechanical energy from the environment.A good match between the motion frequency and the circuit characteristic frequency is critical for the effective power generation of a TENG.However,most TENGs have a time-dependent inherent capacitance(TICTENG),which hinders an optimal design for efficient energy conversion.Here,we propose a novel structure of a TENG with a constant inherent capacitance(CIC-TENG)and a mathematical model is established to provide analytical expressions of key output parameters of the device,which gives numerical simulation results that are in good agreement with the experimentally obtained results.Figures of merit and an optimization strategy are also given as guidelines for the optimization of material selection,geometry design,etc.Furthermore,a disk-formed CIC-TENG(DCIC-TENG)with polarity-switched triboelectric pairs is constructed to harvest unidirectional mechanical energy continuously,achieving an output power density of 55 mW/m^(2).The effects of the motion frequency,the number of electrodes and triboelectric pairs on the charge transfer efficiency of the DCICTENG are assessed and a preferred design strategy is given.Finally,the CIC-TENG demonstrates approximately two-fold advantages in power transfer efficiency over the TIC-TENG,and a DCIC-TENG-based self-powered anemometer was fabricated to measure wind speed in real time. | Lanyue Gan Fan Xia Panpan Zhang Xijun Jiang Yuxuan Liu Simiao Niu Youfan Hu | 2023 | Nano Research2023，16，3： | 0 |
| 18 | Impact of preoperative therapy on surgical outcomes of laparoscopic total gastrectomy for gastric/gastroesophageal junction cancer显示文摘Objective: As laparoscopic surgery is widely applied for primarily treated gastric cancer(GC)/gastroesophageal junction cancer(GEJC) and gains many advantages, the feasibility of laparoscopic total gastrectomy(LTG) for GC/GEJC patients who have received preoperative therapy(PT) has come to the fore. This study aims to analyze the safety and feasibility of LTG after PT for GC/GEJC patients.Methods: We retrospectively analyzed the data of 511 patients with GC/GEJC undergoing LTG, of which 405received LTG(LTG group) and 106 received PT+LTG(PT-LTG group) at Nanfang Hospital between June 2018and September 2022. The surgical outcomes were compared between the two groups.Results: The surgical duration was significantly longer in the PT-LTG group(P<0.001), while the incidence of intraoperative complications(P=1.000), postoperative complications(LTG group vs. PT-LTG group: 26.2% vs.23.6%, P=0.587), the classification of complication severity(P=0.271), and postoperative recovery was similar between two groups. Notably, the incidence of anastomotic complications of esophagojejunostomy was also comparable between the two groups(LTG group vs. PT-LTG group: 5.9% vs. 5.7%, P=0.918). The univariate and multivariate analysis confirmed that positive proximal margin [positive vs. negative: odds ratio(OR)=14.094, 95%confidence interval(95% CI): 2.639-75.260, P=0.002], rather than PT, has an impact on anastomotic complications after LTG(OR=0.945, 95% CI: 0.371-2.408, P=0.905).Conclusions: PT did not increase the surgical risk of LTG for GC/GEJC. Therefore, considering the positive effect of PT on long-term survival, the broader application of PT and LTG for GC/GEJC is supported by our findings. | Yuehong Chen Zhijing Yang Mingli Zhao Chuanjin Xu Yuxuan Zhu Huimin Zhang Huilin Huang Yanmei Peng Yanfeng Hu Tian Lin Tao Chen Hao Chen Liying Zhao Hao Liu Guoxin Li Jiang Yu Xinhua Chen | 2023 | Chinese Journal of Cancer Research2023，35，4： | 0 |

| 20 | Capacitive energy storage from single pore to porous electrode identified by frequency response analysis显示文摘Rate capability,peak power,and energy density are of vital importance for the capacitive energy storage(CES)of electrochemical energy devices.The frequency response analysis(FRA)is regarded as an efficient tool in studying the CES.In the present work,a bi-scale impedance transmission line model(TLM)is firstly developed for a single pore to a porous electrode.Not only the TLM of the single pore is reparameterized but also the particle packing compactness is defined in the bi-scale.Subsequently,the CES properties are identified by FRA,focused on rate capability vs.characteristic frequency,peak power vs.equivalent series resistance,and energy density vs.low frequency limiting capacitance for a single pore to a porous electrode.Based on these relationships,the CES properties are numerically simulated and theoretically predicted for a single pore to a porous electrode in terms of intra-particle pore length,intra-particle pore diameter,inter-particle pore diameter,electrolyte conductivity,interfacial capacitance&exponent factor,electrode thickness,electrode apparent surface area,and particle packing compactness.Finally,the experimental diagnosis of four supercapacitors(SCs)with different electrode thicknesses is conducted for validating the bi-scale TLM and gaining an insight into the CES properties for a porous electrode to a single pore.The calculating results suggest,to some extent,the inter-particle pore plays a more critical role than the intra-particle pore in the CES properties such as the rate capability and the peak power density for a single pore to a porous electrode.Hence,in order to design a better porous electrode,more attention should be given to the inter-particle pore. | Weiheng Li Qiu-An Huang Yu Li Yuxuan Bai Nan Wang Jia Wang Yongming Hu Yufeng Zhao Xifei Li Jiujun Zhang | 2023 | Journal of Energy Chemistry2023，，2： | 0 |
