| 1 | First dark matter search results from the PandaX-Ⅰ experiment显示文摘We report on the first dark-matter(DM)search results from PandaX-I,a low threshold dual-phase xenon experiment operating at the China JinPing Underground Laboratory.In the 37-kg liquid xenon target with 17.4 live-days of exposure,no DM particle candidate event was found.This result sets a stringent limit for low-mass DM particles and disfavors the interpretation of previously-reported positive experimental results.The minimum upper limit,3.7×10-44cm2,for the spin-independent isoscalar DM-particle-nucleon scattering cross section is obtained at a DM-particle mass of 49 GeV/c2at 90%confidence level. | XIAO MengJiao XIAO Xiang ZHAO Li CAO XiGuang CHEN Xun CHEN YunHua CUI XiangYi FANG DeQing FU ChangBo GIBONI Karl L.

| 2 | Molecular Characterization of Human Respiratory Adenovirus Infection in Children from November 2016 to October 2017 in Xining City, China显示文摘Human adenoviruses (HAdVs) belong to the genus Mastadenovirus, family Adenoviridae, and can cause respiratory tract and gastrointestinal tract infections, as well as ocular infections in humans[1]. Till date, a total of 84 unique genotypes of AdVs have been identified and classified as human Mastadenovirus species A to G, and specific types are often associated with certain clinical symptoms, epidemiological settings, and demographic risk groups[2]. Among these species, members of the species HAdV-B (HAdV-3, HAdV-7, HAdV-11, HAdV-16, HAdV-21, HAdV-34, HAdV-35, HAdV-50, etc), HAdV-C (HAdV-1, HAdV-2, HAdV-5, and HAdV-6), and HAdV-E (HAdV-4) have been generally associated with respiratory infections[3]. HAdV infections are mild and self-limited in healthy individuals, whereas they can result in high mortality rates in immunocompetent and immunocompromized patients[4]. | YU Juan LI Hong LU Nan Nan LEI You Ju JIANG Shuang Ying ZHAO Sheng Cang RAO Hua Xiang | 2019 | Biomedical and Environmental Sciences2019，32，1： | 3 |
| 3 | Metathesis of 1-butene and 2-butene to propene over Re_2O_7 supported on macro-mesoporous γ-alumina prepared via a dual template method显示文摘Macro-mesoporous γ-alumina support(MMA) was prepared by a sol-gel route in aqueous medium using pseudo-boehmite as aluminum source and polystyrene microspheres and Pluronic P123 as hard and soft dual templates,respectively.MMA had a BET specific surface area of about 259 m2 g-1,total pore volume of about 1.61 cm3 g-1,macropore diameter of about 102 nm,and mesopore diameter of about 14 nm.Re2O7/MMA and conventional Re2O7/Al2O3 were prepared by a incipient-wetness impregnation method,and their catalytic performances in the metathesis of 1-butene and 2-butene were tested in a fixed-bed tubular reactor.The result showed that Re2O7/MMA possessed higher activity and far longer working life-span than conventional Re2O7/Al2O3. | Lei Sang Sheng-Li Chen Guimei Yuan Min Zheng Ju You Aicheng Chen Rui Li Lanjing Chen | 2012 | Journal of Natural Gas Chemistry2012，21，2： | 2 |
| 4 | Influence of catalyst support structure on ethene/decene metathesis and coke formation over WO_3/SiO_2 catalyst显示文摘8wt%WO3/SiO2 metathesis (disproportionation) catalysts with different pore structures were prepared by the incipient-wetness-impregnation method. The as-synthesized catalysts were characterized by N2 adsorption-desorption, scanning electron microscopy (SEM), X-ray diffraction (XRD), UV-visible diffuse reflectance spectroscopy (DRS) and scanning transmission electron microscopy-high-angle annular dark field (STEM HAADF). The results of STEM HAADF showed that WO3 species were not uniformly distributed on the SiO2 support. The experimental results of 8wt%WO3/SiO2 performance in ethene/decene metathesis revealed that the catalytic effect of 8wt%WO3/SiO2 catalyst and coke formation over it were closely related to the support pore structure: The 8wt%WO3/SiO2 catalyst with a more complicated pore structure showed better catalytic performance but the coke deposition rate was also faster. | Zheng Min Chen Sheng-Li Zhang Jun-Hui Liu Yan Sang Lei You Ju Wang Xiao-Dong | 2013 | Petroleum Science2013，10，1： | 1 |
| 5 | Preparation of mesoporous alumina with large pore size and their supported rhenium oxide catalysts in metathesis of 1-butene and 2-butene to propene显示文摘Mesoporous γ-aluminas with large pore size(up to 19 nm,denoted as MA19) are prepared from dispersed pseudo-boehmite using pluronic P123 as template.It is found that these mesoporous alumina supported rhenium oxide catalysts were more active and have far longer working life-span in gas-phase metathesis of 1-butene and 2-butene to propene than rhenium oxide on conventional alumina with small pore size(5 nm).At 60°C and atmospheric pressure with WHSV = 1 h-1,the similar stable conversions of butene(ca.55%) for all the 13 wt% Re 2 O 7 /alumina catalysts were obtained near the chemical equilibrium,and the stable working life-spans of Re 2 O 7 /MA19 were far longer than that of Re 2 O 7 /Al 2 O 3,being about 70 h and 20 h,respectively. | Lei Sang Sheng-Li Chen Guimei Yuan Zheng Zhou Rui Li Aicheng Chen Min Zheng Ju You | 2012 | Journal of Natural Gas Chemistry2012，21，3： | 1 |
| 6 | Synergistic effect of lithiophilic Zn nanoparticles and N-doping for stable Li metal anodes显示文摘Li metal is the most ideal anode material for next-generation high energy lithium-ion batteries.The uncontrollable growth of Li dendrites,however,hinders its practical application.Herein,we propose the adoption of Zn nanoparticles uniformly embedded in N-doped carbon polyhedra homogeneously built on carbon cloth(Zn@NC@CC)to prevent the formation of Li dendrites.Based on theoretical calculation and experimental observation,lithiophilic Zn nanoparticles and N-doping inside of the assynthesized Zn@NC play a synergistic role in enhancing the adsorption capacity with Li,thus resulting in uniform Li deposition and complete suppression of Li dendrites.Moreover,the porous N-doped carbon polyhedras uniformly distributed on carbon cloth effectively relieves the volume change of Li upon repeated Li stripping/plating process,which contributes to preserving the structural integrity of the whole electrode and hence enhancing its long-term cycling stability.Benefiting from these synergistic effects,the Li-Zn@NC@CC electrode delivers a prolonged lifespan of over 1200 h at 1 mA cm^(-2) with an areal capacity of 1 mA h cm^(-2) in symmetric cells and high Coulombic efficiencies of 95.4%under an ultrahigh capacity of 12 mA h cm^(-2).Remarkably,Li-Zn@NC@CC//LiFePO_(4) full cells deliver a high reversible capacity of 110.2 mA h g^(-1) at 1 C over 200 cycles. | Lei You Shunlong Ju Jianwen Liu Guanglin Xia Zaiping Guo Xuebin Yu | 2022 | Journal of Energy Chemistry2022，31，2： | 0 |
