| 3 | Characteristics of Settings and Etiologic Agents of Foodborne Disease Outbreaks—China,2020显示文摘Introduction:Foodborne diseases are a growing public health problem and have caused a large burden of disease in China.This study analyzed epidemiological characteristics of foodborne diseases in China in 2020 to provide a scientific basis for prevention and control measures.Methods:Data were collected from 30 of 31 provincial-level administrative divisions(PLADs)in the mainland of China,excluding Xizang(Tibet)Autonomous Region,via the National Foodborne Disease Outbreaks Surveillance System・The number and proportion of outbreaks,illnesses,hospitalizations,deaths by setting,pathogen-food category pairs and etiology were calculated.Results:In 2020,7,073 foodborne disease outbreaks were reported,resulting in 37,454 illnesses and 143 deaths.Among the identified pathogens,microbial pathogens were the most common confirmed etiology,accounting for 41.7%of illnesses.Poisonous mushrooms caused the largest proportion of outbreaks(58.0%)and deaths(57.6%).For venues where foodborne disease outbreaks occur,household had the highest number of outbreaks(4,140)and deaths(128),and catering service locations caused the largest proportion of illnesses(59.9%).Outbreaks occurring between June and September accounted for 62.8%of total outbreaks.Conclusions:Foodborne disease outbreaks mainly occurred in households・Microbial pathogens remained the top cause of outbreak-associated illnesses.Poisonous mushrooms were ranked the top cause of deaths in private homes in China.The supervision and management of food safety and health education should be strengthened to reduce the burden of foodborne diseases・Publicity should be increased to reduce the incidence of mushroom poisonings in families,and supervision and management of food should be strengthened to reduce microbial contamination. | Hongqiu Li Weiwei Li Yue Dai Yuyan Jiang Junhua Liang Santao Wang Maoqiang Zhuang Zheng Huang Lizi Xu Bo Xue Jikai Liu Haihong Han Sara M.Pires Ping Fu Yunchang Guo | 2021 | China CDC weekly2021，3，42： | 14 |
| 4 | 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 |
| 5 | CO2 hydrogenation to methanol over Cu/CeO2 and Cu/ZrO2 catalysts:Tuning methanol selectivity via metal-support interaction显示文摘Copper-based catalysts for CO2 hydrogenation to methanol are supported on ZrO2 and CeO2,respectively.Reaction results at 3.0 MPa and temperatures between 200 and 300°C reveal that Cu catalysts supported on ZrO2 and CeO2 exhibit better activity and selectivity than pure Cu catalyst due to Cu-support(ZrO2 and CeO2)interaction.Combining the structural characterizations with in-situ diffuse reflectance infrared Fourier transform spectroscopy(in-situ DRIFTS),Cu/CeO2 shows the higher methanol selectivity due to the formation of main carbonates intermediates,which are closely related with the oxygen vacancies over Cu/CeO2.In contrast,bicarbonate and carboxyl species are observed on Cu/ZrO2,which originates from the hydroxyl groups presented on catalyst surfaces.Difference in CO2 adsorption intermediates results in the distinct methanol selectivity over the two catalysts. | Weiwei Wang Zhenping Qu Lixin Song Qiang Fu | 2020 | Journal of Energy Chemistry2020，29，1： | 11 |
| 6 | Preventive effect of Shenkang injection against high glucose-induced senescence of renal tubular cells显示文摘Shenkang injection (SKI) is a classic prescription composed of Radix Astragali, rhubarb, Astragalus, Safflower, and Salvia. This treatment was approved by the State Food and Drug Administration of China in 1999 for treatment of chronic kidney diseases based on good efficacy and safety. This study aimed to investigate the protective effect of SKI against high glucose (HG)-induced renal tubular cell senescence and its underlying mechanism. Primary renal proximal tubule epithelial cells were cultured in (1) control medium (control group), medium containing 5 mmol/L glucose;(2) mannitol medium (mannitol group), medium containing 5 mmol/L glucose, and 25 mmol/L mannitol;(3) HG medium (HG group) containing 30 mmol/L glucose;(4) SKI treatment at high (200 mg/L), medium (100 mg/L), or low (50 mg/L) concentration in HG medium (HG+ SKI group);or (5) 200 mg/L SKI treatment in control medium (control+ SKI group) for 72 h. HG-induced senescent cells showed the emergence of senescence associated heterochromatin foci, up-regulation of P16INK4 and cyclin D1, increased senescence-associated β-galactosidase activity, and elevated expression of membrane decoy receptor 2. SKI treatment potently prevented these changes in a dose-independent manner. SKI treatment prevented HG-induced up-regulation of pro-senescence molecule mammalian target of rapamycin and p66Shc and down-regulation of anti-senescence molecules klotho, sirt1, and peroxisome proliferator-activated receptor-g in renal tubular epithelial cells. SKI may be a novel strategy for protecting against HG-induced renal tubular cell senescence in treatment of diabetic nephropathy. | Biqiong Fu Jie Yang Jia Chen Lirong Lin Kehong Chen Weiwei Zhang Jianguo Zhang Yani He | 2019 | Frontiers of Medicine2019，13，2： | 8 |
| 7 | Inactivation of SACE_3446, a TetR family transcriptional regulator, stimulates erythromycin production in Saccharopolyspora erythraea显示文摘Erythromycin A is a widely used antibiotic produced by Saccharopolyspora erythraea;however,its biosynthetic cluster lacks a regulatory gene,limiting the yield enhancement via regulation engineering of S.erythraea.Herein,six TetR family transcriptional regulators(TFRs)belonging to three genomic context types were individually inactivated in S.erythraea A226,and one of them,SACE_3446,was proved to play a negative role in regulating erythromycin biosynthesis.EMSA and qRT-PCR analysis revealed that SACE_3446 covering intact N-terminal DNA binding domain specifically bound to the promoter regions of erythromycin biosynthetic gene eryAI,the resistant gene ermE and the adjacent gene SACE_3447(encoding a longchain fatty-acid CoA ligase),and repressed their transcription.Furthermore,we explored the interaction relationships of SACE_3446 and previously identified TFRs(SACE_3986 and SACE_7301)associated with erythromycin production.Given demonstrated relatively independent regulation mode of SACE_3446 and SACE_3986 in erythromycin biosynthesis,we individually and concomitantly inactivated them in an industrial S.erythraea WB.Compared with WB,the WBΔ3446 and WBΔ3446Δ3986 mutants respectively displayed 36%and 65%yield enhancement of erythromycin A,following significantly elevated transcription of eryAI and ermE.When cultured in a 5 L fermentor,erythromycin A ofWBΔ3446 and WBΔ3446Δ3986 successively reached 4095 mg/L and 4670 mg/L with 23%and 41%production improvement relative to WB.The strategy reported here will be useful to improve antibiotics production in other industrial actinomycete. | Hang Wu Yansheng Wang Li Yuan Yongrong Mao Weiwei Wang Lin Zhu Panpan Wu Chengzhang Fu Rolf Muller David T.Weaver Lixin Zhang Buchang Zhang | 2016 | Synthetic and Systems Biotechnology2016，1，1： | 7 |
| 8 | Building a sequence map of the pig pan-genome from multiple de novo assemblies and Hi-C data显示文摘Pigs were domesticated independently in the Near East and China,indicating that a single reference genome from one individual is unable to represent the full spectrum of divergent sequences in pigs worldwide.Therefore,12 de novo pig assemblies from Eurasia were compared in this study to identify the missing sequences from the reference genome.As a result,72.5 Mb of nonredundant sequences(~3% of the genome)were found to be absent from the reference genome(Sscrofa11.1)and were defined as pan-sequences.Of the pan-sequences,9.0 Mb were dominant in Chinese pigs,in contrast with their low frequency in European pigs.One sequence dominant in Chinese pigs contained the complete genic region of the tazarotene-induced gene 3(TIG3)gene which is involved in fatty acid metabolism.Using flanking sequences and Hi-C based methods,27.7% of the sequences could be anchored to the reference genome.The supplementation of these sequences could contribute to the accurate interpretation of the 3D chromatin structure.A web-based pan-genome database was further provided to serve as a primary resource for exploration of genetic diversity and promote pig breeding and biomedical research. | Xiaomeng Tian Ran Li Weiwei Fu Yan Li Xihong Wang Ming Li Duo Du Qianzi Tang Yudong Cai Yiming Long Yue Zhao Mingzhou Li Yu Jiang | 2020 | Science China(Life Sciences)2020，63，5： | 7 |
| 9 | Micro-droplet Digital Polymerase Chain Reaction and Real-Time Quantitative Polymerase Chain Reaction Technologies Provide Highly Sensitive and Accurate Detection of Zika Virus显示文摘The establishment of highly sensitive diagnostic methods is critical in the early diagnosis and control of Zika virus(ZIKV)and in preventing serious neurological complications of ZIKV infection. In this study, we established micro-droplet digital polymerase chain reaction(ddPCR) and real-time quantitative PCR(RT-qPCR) protocols for the detection of ZIKV based on the amplification of the NS5 gene. For the ZIKV standard plasmid, the RT-qPCR results showed that the cycle threshold(Ct) value was linear from 10~1 to 10~8 copy/l L, with a standard curve R^2 of 0.999 and amplification efficiency of 92.203%;however, a concentration as low as 1 copy/l L could not be detected. In comparison with RT-qPCR, the dd PCR method resulted in a linear range of 10~1–10~4 copy/l L and was able to detect concentrations as low as 1 copy/l L. Thus, for detecting ZIKV from clinical samples, RT-qPCR is a better choice for high-concentration samples(above 10~1 copy/l L),while ddPCR has excellent accuracy and sensitivity for low-concentration samples. These results indicate that the ddPCR method should be of considerable use in the early diagnosis, laboratory study, and monitoring of ZIKV. | Yuan Hui Zhiming Wu Zhiran Qin Li Zhu Junhe Liang Xujuan Li Hanmin Fu Shiyu Feng Jianhai Yu Xiaoen He Weizhi Lu Weiwei Xiao Qinghua Wu Bao Zhang Wei Zhao | 2018 | Virologica Sinica2018，33，3： | 6 |

| 11 | Healthcare data analytics:using a metadata annotation approach for integrating electronic hospital records显示文摘The data in electronic medical records(EMR)are complex in structure.They are independent,yet related to each other.In order to improve information access through the use of EMR,annotating work on these data is necessary.The annotation on metadata,the resource data which contain a meta-model of the database,is the basis of the annotating work if a semi-automated or an automated annotating approach which aims at making the database more accessible is expected.In this study,a method has been proposed to transform the terms which cannot be matched directly by changing them literally but maintaining their semantics,and then annotating them indirectly.After the transforming work,a refinement method which is reducible to phrase sense disambiguation(PSD)is employed to ensure accuracy.A pilot study on a hospital database has been conducted to test the accuracy and effectiveness of the proposed method. | Boyi Xu Ke Xu LiuLiu Fu Ling Li Weiwei Xin Hongming Cai | 2016 | Journal of Management Analytics2016，3，2： | 6 |
| 12 | Changes of Extreme Precipitation and its Associated Mechanisms in Northwest China显示文摘Characterized by scarce water resources and fragile ecosystems,Northwest China(NWC)has experienced a climate shift from warm-dry to warm-wet conditions since the 1980s that has garnered extensive concern in recent years.In this study,the variability in extreme precipitation(EP)during 1961-2016 in different climate zones of NWC and the possible mechanisms for this variation are investigated.The results show that the EP trends significantly increased in most of the westerly zone(WZ)and plateau zone(PZ),while the EP trends did not significantly decrease in the monsoon zone(MZ).The start dates of extreme precipitation(SDEP)and end dates of extreme precipitation(EDEP)advanced and were postponed,respectively,in the WZ and PZ,while the opposite occurred in the MZ.Summer atmospheric circulation,water vapor transport,and atmospheric instability over NWC varied greatly with the interdecadal shift in EP before and after 1986.During 1986-2016,upper-level divergence and lower-level convergence occurred in the MZ and PZ,which strengthened ascending flow.In addition,the summer water vapor and atmospheric instability increased in the WZ and PZ.These characteristics created favorable conditions for increased occurrences of EP in the WZ and PZ in summer.Conversely,the upper-level convergence and lower-level divergence in the MZ strengthened descending flow.Decreases in summer water vapor and atmospheric instability occurred in the MZ after 1986.Hence,the environmental conditions in the MZ may have prevented the occurrence and development of EP in summer during 1986-2016. | Shan LU Zeyong HU Haipeng YU Weiwei FAN Chunwei FU Di WU | 2021 | Advances in Atmospheric Sciences2021，38，10： | 4 |
| 13 | Responses of nighttime sap flow to atmospheric and soil dryness and its potential roles for shrubs on the Loess Plateau of China显示文摘Aims Nocturnal sap flow(E_(night))has been observed in a variety of plant species and environmental conditions.In water-limited environ-ments,E_(night) is important in the regulation of plant water’s physi-ology.This study was designed to evaluate the way in which E_(night)(defined as sap flow from 20:30 to 06:00)responded to changes in the atmospheric vapor pressure deficit(VPD)and the soil water con-tent(SWC),and explored its potential physiological significance for different plant species in a semi-arid area.Methods We selected three shrub species:Vitex negundo L.(VN),Hippophae rhamnoides L.(HR)and Spiraea pubescens Turcz(SP)in the semi-arid Loess Plateau of China.The plots of the three communities dominated by each of three species were on the same hill slope.Half-hourly sap flow density was measured in six to seven sample stems for each species during the main grow-ing season(June to August 2015).VPD,SWC,leaf water potential(Ψleaf)and stomatal conductance(G_(s))were measured at the same time.Regression analyses were conducted to determine the rela-tionships between E_(night),E_(day),E_(night)/E_(daily),VPD and SWC at half-hourly and daily time scales,as well as between E_(night),E_(day) andΨleaf.Important Findings The mean values of E_(night) and E_(day) were higher,but E_(night)/E_(daily) val-ues were lower for VN compared to HR and SP.The responses of sap flow density to VPD and SWC varied at different temporal scales.VPD was the dominant factor that affected E_(night) and E_(day) at the half-hourly scale for all three species.In contrast,SWC was the key factor that influenced E_(day) at the daily time scale.The values of E_(day) and E_(night)/E_(daily) correlated negatively with SWC because the effect of SWC was stronger on E_(day) than on E_(night).Although the low fraction of E_(night)/E_(daily)(4%-7%)may indicate a minor short-term effect of E_(night) on the standing water balance,E_(night) had eco-physiologically significance to the plants.The discrepancy inΨleaf between sunset and the following day’s predawn(ΔΨ)indicated that stem refilling occurred during this period.SP had the higher fraction of recharge water among the three species,as it had the relatively higher value ofΔΨ/E_(night).E_(night) had positive relation-ship with predawn Gs.The increased Gs facilitated rapid onset of photosynthesis in the early morning.In addition,the positive correlation between E_(night) and E_(day) from 06:00 to 10:30 suggested that E_(night) was beneficial for transpiration in the following morning.The responses of E_(night) to VPD and SWC indicated differences in plant adaptation to drought stress,which provides important infor-mation for our understanding of the reactions to climate changes among species in semi-arid areas. | Weiwei Fang Nan Lu Yu Zhang Lei Jiao Bojie Fu | 2018 | Journal of Plant Ecology2018，11，5： | 3 |
| 14 | Modes of genetic adaptations underlying functional innovations in the rumen显示文摘The rumen is the hallmark organ of ruminants and hosts a diverse ecosystem of microorganisms that facilitates efficient digestion of plant fibers.We analyzed 897 transcriptomes from three Cetartiodactyla lineages:ruminants,camels and cetaceans,as well as data from ruminant comparative genomics and functional assays to explore the genetic basis of rumen functional innovations.We identified genes with relatively high expression in the rumen,of which many appeared to be recruited from other tissues.These genes show functional enrichment in ketone body metabolism,regulation of microbial community,and epithelium absorption,which are the most prominent biological processes involved in rumen innovations.Several modes of genetic change underlying rumen functional innovations were uncovered,including coding mutations,genes newly evolved,and changes of regulatory elements.We validated that the key ketogenesis rate-limiting gene(HMGCS2)with five ruminant-specific mutations was under positive selection and exhibits higher synthesis activity than those of other mammals.Two newly evolved genes(LYZ1 and DEFB1)are resistant to Gram-positive bacteria and thereby may regulate microbial community equilibrium.Furthermore,we confirmed that the changes of regulatory elements accounted for the majority of rumen gene recruitment.These results greatly improve our understanding of rumen evolution and organ evo-devo in general. | Xiangyu Pan Yudong Cai Zongjun Li Xianqing Chen Rasmus Heller Nini Wang Yu Wang Chen Zhao Yong Wang Han Xu Songhai Li Ming Li Cunyuan Li Shengwei Hu Hui Li Kun Wang Lei Chen Bin Wei Zhuqing Zheng Weiwei Fu Yue Yang Tingting Zhang Zhuoting Hou Yueyang Yan Xiaoyang Lv Wei Sun Xinyu Li Shisheng Huang Lixiang Liu Shengyong Mao Wenqing Liu Jinlian Hua Zhipeng Li Guojie Zhang Yulin Chen Xihong Wang Qiang Qiu Brian PDalrymple Wen Wang Yu Jiang | 2021 | Science China(Life Sciences)2021，64，1： | 3 |
| 15 | Comprehensive and high-resolution emission inventory of atmospheric pollutants for the northernmost cities agglomeration of Harbin-Changchun,China:Implications for local atmospheric environment management显示文摘Using a bottom-up estimation method,a comprehensive,high-resolution emission inventory of gaseous and particulate atmospheric pollutants for multiple anthropogenic sectors with typical local sources has been developed for the Harbin-Changchun city agglomeration(HCA).The annual emissions for CO,NO_(x),SO_(2),NH_(3),VOC S,PM_(2.5),PM 10,BC and OC during 2017 in the HCA were estimated to be 5.82 Tg,0.70 Tg,0.34 Tg,0.75 Tg,0.81 Tg,0.67 Tg,1.59 Tg,0.12 Tg and 0.26 Tg,respectively.For PM 10 and SO_(2),the emissions from industry processes were the dominant contributors representing 54.7%and 49.5%,respectively,of the total emissions,while 95.3%and 44.5%of the total NH_(3)and NO x emissions,respectively,were from or associated with agricultural activities and transportation.Spatiotemporal distributions showed that most emissions(except NH_(3))occurred in November to March and were concentrated in the central cities of Changchun and Harbin and the surrounding cities.Open burning of straw made an important contribution to PM_(2.5)in the central regions of the northeastern plain during autumn and spring,while domestic coal combustion for heating purposes was significant with respect to SO_(2)and PM_(2.5)emissions during autumn and winter.Furthermore,based on Principal Component Analysis and Multivariable Linear Regression model,air temperature,relative humidity,electricity and energy consumption,and the urban and rural population were optimized to be representative indicators for rapidly assessing the magnitude of regional atmospheric pollutants in the HCA.Such indicators and equations were demonstrated to be useful for local atmospheric environment management. | Mengduo Zhang Weiwei Chen Xiangjin Shen Hongmei Zhao Chengkang Gao Xuelei Zhang Wei Liu Chengjiang Yang Yang Qin Shichun Zhang Jing Fu Daniel Tong Aijun Xiu | 2021 | Journal of Environmental Sciences2021，33，6： | 3 |

| 17 | An investigation of Zr/Ce ratio influencing the catalytic performance of CuO/Ce1-xZrxO2 catalyst for CO2 hydrogenation to CH3OH显示文摘A series of CuO/Ce1-xZrxO2 catalysts(x=0.2,0.4,0.6 and 0.8)are applied to elaborate the effect of the Zr/Ce ratio on the catalytic performance of CO2 hydrogenation to CH3OH.The best catalytic performance is achieved with CuO/Ce0.4Zr0.6O2,exhibiting XCO2=13.2%and YCH3OH=9.47%(T=280℃,P=3 MPa).The formation of dispersed surface CuO species and larger number of oxygen vacancies are detected over CuO/Ce0.4Zr0.6O2 due to stronger interaction between CuO and Ce0.4Zr0.6O2,resulting in the superior activation ability for H2 and CO2 respectively.Additionally,the evidence is provided by in situ DRIFTS under the activity test pressure(3 MPa)that bi/m-HCOO* species are preferable for accumulating over ceria-rich(CuO/Ce0.6Zr0.4O2 and CuO/Ce0.8Zr0.2O2)catalysts while zirconia-rich(CuO/Ce0.4Zr0.6O2 and CuO/Ce0.2Zr0.8O2)catalysts are benefit to encourage the transformation of bi/m-HCOO* species to CH3OH.The abundant population and high activity of intermediate species over CuO/Ce0.4Zr0.6O2 give a strong positive effect on the catalytic performance. | Weiwei Wang Zhenping Qu Lixin Song Qiang Fu | 2020 | Journal of Energy Chemistry2020，29，8： | 2 |

Herein we construct three kinds of Cu/Ce_(x)Zr_(y)O_(z)(CCZ) catalysts with different crystal phases of Ce_(x)Zr_(y)O_(z)solid solutions, which demonstrate distinct activity and methanol selectivity in the order of metastable tetragonal-CCZ(CCZ-t’’, parts of oxygen in Ce_(x)Zr_(y)O_(z) were replaced by tetragonal phase from cubic fluorite phase) > tetragonal-CCZ(CCZ-t) > cubic-CCZ(CCZ-c) for CO_(2) hydrogenation to methanol. Structural analysis reveals that oxygen vacancies, surface hydroxyls and unsaturated Cu species of CCZ all follow the same sequence as that of activity and methanol selectivity,indicating that the above features are beneficial to improve the catalytic reaction performance.Temperature programmed experiments and mechanism studies show that the interface between Cu and tetragonal(t and t’’) Ce_(x)Zr_(y)O_(z) can promote CO_(2) adsorption, and the adsorbed CO_(2) is more reactive and can generate active bidentate carbonate species, which can be hydrogenated to form active monodentate and bidentate formate species under CO_(2) and H_(2) atmosphere. These intermediates should be crucial to the formation of methanol product. CCZ-t’’has stronger H_(2) activation ability than CCZ-t, which makes the former catalyst have more intermediates and higher methanol selectivity. In contrast, CO_(2) mainly adsorbs on cubic Ce_(x)Zr_(y)O_(z) support of CCZ-c, but its H_(2) spillover ability is low, which hinders the reaction process. In addition, the strong adsorption of surface intermediates on CCZ-c is also not conducive to methanol formation. Results here demonstrate that constructing active Cu-support interfaces may be an important approach to design effective catalyst for CO_(2)hydrogenation. | Na Li Weiwei Wang Lixin Song Hui Wang Qiang Fu Zhenping Qu | 2022 | Journal of Energy Chemistry2022，31，5： | 2 |
| 20 | Long-term follow-up of optic neuropathy in chronic low cerebrospinal fluid pressure monkeys: the Beijing Intracranial and Intraocular Pressure(iCOP) Study显示文摘Dear Editor,Clinical and anatomic investigations strongly suggest that a low orbital cerebrospinal fluid pressure (CSFP), parallel to an elevated intraocular pressure (IOP), may have a role in the pathogenesis of optic neuropathy (Ren et al., 2011, Wang et al., 2012). Optic neuropathy including glaucoma demonstrated structural alterations in the optic nerve head (ONH)and retinal nerve fiber layer (RNFL), as well as functional abnormalities such as visual field (VF) that eventually cause severe visual impairment and blindness. | Jing Li Diya Yang Jacky MKKwong Jidi Fu Ruowu Hou Jost BJonas Huaizhou Wang Zheng Zhang Weiwei Chen Zhen Li Jinghong Sang Xiaobin Xie Ruojin Ren Robert NWeinreb Ningli Wang | 2020 | Science China(Life Sciences)2020，63，11： | 2 |
