| 2 | 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 |
| 3 | A new kind of optimal second-order symplectic scheme for seismic wave simulations显示文摘Here we introduce generalized momentum and coordinate to transform seismic wave displacement equations into Hamiltonian system.We define the Lie operators associated with kinetic and potential energy,and construct a new kind of second order symplectic scheme,which is extremely suitable for high efficient and long-term seismic wave simulations.Three sets of optimal coefficients are obtained based on the principle of minimum truncation error.We investigate the stability conditions for elastic wave simulation in homogeneous media.These newly developed symplectic schemes are compared with common symplectic schemes to verify the high precision and efficiency in theory and numerical experiments.One of the schemes presented here is compared with the classical Newmark algorithm and third order symplectic scheme to test the long-term computational ability.The scheme gets the same synthetic surface seismic records and single channel record as third order symplectic scheme in the seismic modeling in the heterogeneous model. | LIU ShaoLin LI XiaoFan WANG WenShuai LIU YouShan ZHANG MeiGen ZHANG Huan | 2014 | Science China Earth Sciences2014，57，4： | 8 |
| 4 | Polyoxometalate-based silica-supported ionic liquids for heterogeneous oxidative desulfurization in fuels显示文摘With the aim of deep desulfurization, silica-supported polyoxometalate-based ionic liquids were successfully prepared by a one-pot hydrothermal process and employed in heterogeneous oxidative desulfurization of various sulfur compounds. The compositions and structures of the hybrid samples were characterized by various methods such as FT-IR, XPS, Raman,UV–Vis, wide-angle XRD and N_2 adsorption–desorption. The experimental results indicated that the hybrid materials presented a high dispersion of tungsten species and excellent catalytic activity for the removal of 4,6-dimethyldibenzothiophene without any organic solvent as extractant, and the sulfur removal could reach 100.0% under mild conditions.The catalytic performance on various substrates was also investigated in detail. After cycling seven cycles, the sulfur removal of the heterogeneous system still reached 93.0%. The GC-MS analysis results demonstrated that the sulfur compound was first adsorbed by the catalyst and subsequently oxidized to its corresponding sulfone. | Ming Zhang Miao Wang Jiapeng Yang Hongping Li Jiaqi Liu Xiao Chen Wenshuai Zhu Huaming Li | 2018 | Petroleum Science2018，15，4： | 5 |
| 5 | Boosting photocatalytic degradation of RhB via interfacial electronic effects between Fe-based ionic liquid and g-C_3N_4显示文摘The Fe-based ionic liquid doped g-C_3N_4(Fee CN) photocatalyst was firstly prepared base on ultrathin g-C_3N_4 obtained by multiple calcination method with a metal-based reactive ionic liquid [Omim]FeCl_4 for the degradation of Rhodamine B(RhB). Experimental results revealed that Fe3+species were doped into the framework of g-C_3N_4. The effect of the amount of Fe-doping on the catalytic activity was performed. The result showed that the Fee CN could effectively degrade RhB under the condition of visible light irradiation. The photocurrent analysis showed that the incorporation of Fe^(3+)into g-C_3N_4 material could accelerate the separation of the photogenerated carriers significantly.At the same time, the reactive species generated during the photodegradation process were tested by radicals trapping experiments and electron spin resonance(ESR). It was proposed that the synergistic effect of■ and ·OH contributed to degrade RhB efficiently. | Xiaowei Li Bin Wang Yuhong Huang Jun Di Jiexiang Xia Wenshuai Zhu Huaming Li | 2019 | Green Energy & Environment2019，4，2： | 4 |
| 6 | Scalable and facile synthesis of V_(2)O_(5) nanoparticles via ball milling for improved aerobic oxidative desulfurization显示文摘In recent years, transition-metal oxides(TMOs) have been long employed for aerobic oxidative desulfurization. However, the inherent bottlenecks, such as the low explosion of active sites, limit the application of bulk TMOs catalyst. In this study, V_(2)O_(5) nanoparticles with oxygen vacancies were prepared in large-scale via facile ball milling strategy with adding oxalic acid as a reducing agent. The as-prepared catalysts exhibit remarkable sulfur removal for oils with different initial S-concentrations and different substrates. Sulfur removal could reach up to 99.7%(< 2 ppm) under the optimized reaction conditions. This work provides a feasible desulfurization strategy for fuel oils. | Yiru Zou Chao Wang Hanxiang Chen Haiyan Ji Qian Zhu Wenshu Yang Linlin Chen Zhigang Chen Wenshuai Zhu | 2021 | Green Energy & Environment2021，6，2： | 4 |
| 7 | Amorphous TiO_2-supported Keggin-type ionic liquid catalyst catalytic oxidation of dibenzothiophene in diesel显示文摘Supported ionic liquid(IL) catalysts [C_nmim]_3PMo_(12)O_(40)/Am TiO_2(amorphous TiO_2) were synthesized through a one-step method for extraction coupled catalytic oxidative desulfurization(ECODS) system. Characterizations such as FTIR, DRS,wide-angle XRD, N_2 adsorption–desorption and XPS were applied to analyze the morphology and Keggin structure of the catalysts. In ECODS with hydrogen peroxide as the oxidant, it was found that ILs with longer alkyl chains in the cationic moiety had a better effect on the removal of dibenzothiophene. The desulfurization could reach 100% under optimal conditions, and GC–MS analysis was employed to detect the oxidized product after the reaction. Factors affecting the desulfurization efficiencies were discussed, and a possible mechanism was proposed. In addition, cyclic experiments were also conducted to investigate the recyclability of the supported catalyst. The catalytic activity of [C_(16)mim]_3 PMo_(12)O_(40)/Am TiO_2 only dropped from 100% to 92.9% after ten cycles, demonstrating the good recycling performance of the catalyst and its potential industrial application. | Zhendong Yu Donghui Wang Suhang Xun Minqiang He Ruliang Ma Wei Jiang Hongping Li Wenshuai Zhu Huaming Li | 2018 | Petroleum Science2018，15，4： | 3 |
| 8 | Clinical characteristics in lymphangioleiomyomatosis-related pulmonary hypertension: an observation on 50 patients显示文摘Lymphangioleiomyomatosis (LAM) is a rare diffuse cystic lung disease. Knowledge on LAM-related pulmonary hypertension (PH) is limited. This study aimed to analyze the clinical characteristics of LAM with elevated pulmonary artery pressure (PAP) and evaluate the potential efficacy of sirolimus. The study involved 50 LAM patients who underwent echocardiography. According to the tricuspid regurgitation velocity (TRV), these patients were divided into the TRV≤2.8 m/s group and TRV>2.8 m/s group. Both groups comprised 25 females with an average age of 38.6±8.1 and 41.5±8.9 years. In the TRV>2.8 m/s group, the estimated systolic PAP (SPAP) was significantly elevated (52.08±12.45 mmHg vs. 30.24±5.25 mmHg, P<0.01). Linear analysis showed that SPAP was correlated with forced expiratory volume in 1 s (FEV1), diffusing capacity of the lungs for carbon monoxide, alveolar arterial oxygen gradient (PA-aO2), and 6 min walking distance (r =-0.392,-0.351, 0.450, and -0.591, respectively;P<0.05), in which PA-aO2 was a risk factor for SPAP elevation (β= 0.064, OR= 1.066, P<0.05). Moreover, in 10 patients who received sirolimus therapy, SPAP decreased from 57.0±12.6 mmHg to 35.2±11.1 mmHg. The study showed that LAM patients with PH exhibit poor pulmonary function and hypoxemia and may benefit from sirolimus treatment. | Xiuxiu Wu Wenshuai Xu Jun Wang Xinlun Tian Zhuang Tian Kaifeng Xu | 2019 | Frontiers of Medicine2019，13，2： | 3 |

| 10 | A comparative study of the extractive desulfurization mechanism by Cu(Ⅱ)and Zn-based imidazolium ionic liquids显示文摘A comparative study of the extractive desulfurization(EDS) mechanism by Cu(Ⅱ) and Zn-based ILs([C_4mim]_2[MCl_4], M ? Cu(Ⅱ) or Zn)has been performed. It is found that the p–p interaction and C-H/p interaction play important roles in EDS for both Cu(Ⅱ) and Zn-based ILs,which is different from Al, Fe-based ILs. In the gas phase models, the interaction energy between Zn-based ILs and dibenzothiophene(DBT) is stronger than the interaction energy of Cu(Ⅱ)-based ILs. In order to consider the solvent effect, a generic ionic liquid of solvation model has been implemented, which is few considered in the previous calculations of EDS. It is interesting to find that the gap of interaction energies between Cu(Ⅱ), Zn-based ILs and DBT are reduced when the solvent effect is considered. In addition, by combined discussion of currently theoretical and experimental evidences for metal-based ILs with different compositions, we firstly propose that the EDS performance should be influenced by the balance of the contribution of cation, metal-based anion, metal chlorides and the viscosity. | Hongping Li Beibei Zhang Wei Jiang Wenshuai Zhu Ming Zhang Chao Wang Jingyu Pang Huaming Li | 2019 | Green Energy & Environment2019，4，1： | 2 |

| 12 | 3D-printing of integrated spheres as a superior support of phosphotungstic acid for deep oxidative desulfurization of fuel显示文摘Construction of catalysts with integral structure for oxidative reaction process is an essential promotion to catalysts in industrial application.In this work,a 3D printing method was employed to prepare 3D printed spheres(3D-PSs),followed by carbonization to form 3D carbon spheres(3D-CSs).Then,a 3D-CSs supported phosphotungstic acid(HPW/3D-CSs)was prepared for deep oxidative desulfurization.Compared with traditional powder catalysts,the as-prepared catalyst is easy to be operated and separated from oil products.The supported catalyst possesses excellent catalytic performance and the removal of DBT,4-MDBT and 4,6-DMDBT in fuel oil,reaching^100%of sulfur removal.The effects of various experimental parameters on desulfurization efficiency were considered to optimize reaction conditions.Moreover,the catalyst shows excellent thermal and chemical stability,with no obvious decrease in desulfurization activity after 5 cycles.GC–MS analysis indicates DBT sulfone was the solely oxidized product of DBT. | Jie Zhu Peiwen Wu Linlin Chen Jing He Yingcheng Wu Chao Wang Yanhong Chao Linjie Lu Minqiang He Wenshuai Zhu Huaming Li | 2020 | Journal of Energy Chemistry2020，29，6： | 2 |
| 13 | Bioprinting and regeneration of auricular cartilage using a bioactive bioink based on microporous photocrosslinkable acellular cartilage matrix显示文摘Tissue engineering provides a promising strategy for auricular reconstruction.Although the first international clinical breakthrough of tissue-engineered auricular reconstruction has been realized based on polymer scaffolds,this approach has not been recognized as a clinically available treatment because of its unsatisfactory clinical efficacy.This is mainly since reconstruction constructs easily cause inflammation and deformation.In this study,we present a novel strategy for the development of biological auricle equivalents with precise shapes,low immunogenicity,and excellent mechanics using auricular chondrocytes and a bioactive bioink based on biomimetic microporous methacrylate-modified acellular cartilage matrix(ACMMA)with the assistance of gelatin methacrylate(GelMA),poly(ethylene oxide)(PEO),and polycaprolactone(PCL)by integrating multi-nozzle bioprinting technology.Photocrosslinkable ACMMA is used to emulate the intricacy of the cartilage-specific microenvironment for active cellular behavior,while GelMA,PEO,and PCL are used to balance printability and physical properties for precise structural stability,form the microporous structure for unhindered nutrient exchange,and provide mechanical support for higher shape fidelity,respectively.Finally,mature auricular cartilage-like tissues with high morphological fidelity,excellent elasticity,abundant cartilage lacunae,and cartilage-specific ECM deposition are successfully regenerated in vivo,which provides new opportunities and novel strategies for the fabrication and regeneration of patient-specific auricular cartilage. | Litao Jia Yujie Hua Jinshi Zeng Wenshuai Liu Di Wang Guangdong Zhou Xia Liu Haiyue Jiang | 2022 | Bioactive Materials2022，7，10： | 2 |

| 17 | Synchronous activation of Ag nanoparticles and BiOBr for boosting solar-driven CO_(2)reduction显示文摘Artificial photosynthesis of valuable chemicals from CO_(2)is a potential way to achieve sustainable carbon cycle.The CO_(2)conversion activity is still inhibited by the sluggish charge kinetics and poor CO_(2)activation.Herein,Ag nanoparticles coupled Bi OBr have been constructed by in-situ photoreduction strategy.The crafting of interface between Ag nanoparticles and Bi OBr nanosheets,achieving an ultra-fast charge transfer.The Bi OBr semiconductor excited electrons and plasmonic Ag nanoparticles generated high-energy hot electrons synchronous accelerates the C=O double bond activation.Thus,the optimized Ag/BiOBr-2 heterostructure shows excellent CO_(2)photoreduction activity with CO production of 133.75 and 6.83μmol/g under 5 h of 300 W Xe lamp and visible light(λ>400 nm)irradiation,which is 1.51 and 2.81 folds versus the pristine Bi OBr,respectively.The mechanism of CO_(2)photoreduction was in-depth understood through in-situ FT-IR spectrum and density functional theory calculations.This study provides some new perspectives into efficient photocatalytic CO_(2)reduction. | Gaopeng Liu Lin Wang Bin Wang Xingwang Zhu Jinman Yang Pengjun Liu Wenshuai Zhu Ziran Chen Jiexiang Xia | 2023 | Chinese Chemical Letters2023，34，6： | 1 |
| 18 | Selenium-enriched Cardamine violifolia protects against sepsis-induced intestinal injury by regulating mitochondrial fusion in weaned pigs显示文摘Sepsis is a life-threatening organ dysfunction caused by the dysregulated response of the host to an infection, and treatments are limited. Recently, a novel selenium source, selenium-enriched Cardamine violifolia(SEC) has attracted much attention due to its anti-inflammatory and antioxidant properties, but little is known about its role in the treatment of sepsis. Here, we found that SEC alleviated LPS-induced intestinal damage, as indicated by improved intestinal morphology, and increased disaccharidase activity and tight junction protein expression. Moreover, SEC ameliorated the LPS-induced release of pro-inflammatory cytokines, as indicated by decreased IL-6 level in the plasma and jejunum. Moreover, SEC improved intestinal antioxidant functions by regulating oxidative stress indicators and selenoproteins. In vitro, TNF-α-challenged IPEC-1 cells were examined and showed that selenium-enriched peptides, which are the main functional components extracted from Cardamine violifolia(CSP), increased cell viability, decreased lactate dehydrogenase activity and improved cell barrier function. Mechanistically, SEC ameliorated LPS/TNF-α-induced perturbations in mitochondrial dynamics in the jejunum and IPEC-1 cells. Moreover, CSPmediated cell barrier function is primarily dependent on the mitochondrial fusion protein MFN2 but not MFN1. Taken together,these results indicate that SEC mitigates sepsis-induced intestinal injury, which is associated with modulating mitochondrial fusion. | Dan Wang Yanling Kuang Qingqing Lv Wenshuai Xie Xiao Xu Huiling Zhu Yue Zhang Xin Cong Shuiyuan Cheng Yulan Liu | 2023 | Science China(Life Sciences)2023，66，9： | 1 |
