| 2 | Novel Surface Design of Deployable Reflector Antenna Based on Polar Scissor Structures显示文摘Space-deployable mechanisms can be used as supporting structures for large-diameter antennas in space engineering.This study proposes a novel method for constructing the surface design of space reflector antennas based on polar scissor units.The concurrency and deployability equations of the space scissor unit with definite surface constraints are derived using the rod and vector methods.Constraint equations of the spatial transformation for space n-edge polar scissor units are summarized.A new closed-loop deployable structure,called the polar scissor deployable antenna(PSDA),is designed by combining planar polar scissor units with spatial polar scissor units.The overconstrained problem is solved by releasing the curve constraint that locates at the end-point of the planar scissor mechanism.Kinematics simulation and error analysis are performed.The results show that the PSDA can effectively fit the paraboloid of revolution.Finally,deployment experiments verify the validity and feasibility of the proposed design method,which provides a new idea for the construction of large space-reflector antennas. | Pengyuan Zhao Jinguo Liu Chenchen Wu Yangmin Li Keli Chen | 2020 | Chinese Journal of Mechanical Engineering2020,33,5: | 7 |
| 3 | Effectiveness of Catch-Up Vaccinations after COVID-19 Containment--China,2020显示文摘Introduction:In the early stages of the coronavirus disease 2019(COVID-19)epidemic in China,the highest level of public health emergency response(Level 1 Response)was launched in all province-level administrative divisions(PLADs)across the country.Provision of vaccination services was selectively suspended due to the physical distancing and gathering restrictions required of Level 1 Response.The purpose of this paper is to evaluate the impact of COVID-19 on vaccination services and the effectiveness of selective vaccination service suspension and catch-up vaccinations in China.Methods:Vaccine doses administered,routine vaccination coverage levels,catch-up vaccine doses administered,and coverage levels after the catch-up campaign were determined from individual vaccination records in sampled clinics,standard routine immunization administrative coverage reports,and catch-up vaccination activity reports submitted by PLADs between October 2019 and October 2020.Results:National Immunization Program(NIP)and non-NIP vaccine doses administered in sampled clinics decreased by 80% and 90%,respectively,compared with doses administered before the COVID-19 pandemic.Coverage with the birth dose of hepatitis B vaccine(HepB1)and the Bacillus Calmette-Guérin vaccine(BCG)—two vaccinations recommended to continue throughout the epidemic due to their timecritical nature—were maintained at over 85%,while coverage of other NIP vaccines decreased to below 60%by February 2020.Catch-up vaccination coverage of the 29 PLADs,excluding Xinjiang and Xizang(Tibet),began in April 2020 and exceeded 90%;Hubei catch-up coverage was 95% by October 2020.Conclusions and Implications for Public Health Practice:The COVID-19 pandemic had a great impact on China’s vaccination services.During the epidemic and time of local transmission of the coronavirus,HepB1,BCG,rabies vaccine for postexposure prophylaxis,and tetanus antitoxin(TAT)for wound prophylaxis were maintained at high levels.Of the 69 million vaccine doses postponed during the time of local transmission of the coronavirus,94% were administered in the catch-up campaign.China’s pandemic immunization practices may provide evidence for other countries’immunization programs. | Jing Wu Wenzhou Yu Lei Cao Lingsheng Cao Lance Rodewald Jiakai Ye Yifan Song Li Li Xiaoxue Liu Ning Wen Fuzhen Wang Lixin Hao Yixing Li Hui Zheng Keli Li Chao Ma Dan Wu Yanmin Liu Guomin Zhang Zhijie An Huaqing Wang Zundong Yin | 2020 | China CDC weekly2020,2,50: | 6 |
| 4 | Vapor-phase growth of high-quality wafer-scale two-dimensional materials显示文摘Emerging two-dimensional(2D)materials have stimulated tremendous scientific and industrial interests due to their diverse and tunable physical,chemical,and mechanical properties.The scalable production of high-quality wafer-scale 2D materials has become significantly essential to bring us closer to practical industrial applications,particularly in electronic devices.Vapor-phase growth provides attractive opportunities for the synthesis of large-area and high-quality 2D materials.In this review,we will emphasize vapor-phase growth strategies from three aspects,including suppressing nucleation,seamless stitching,and evolutionary selection growth.We discuss the general understanding of the related fundamental mechanism and specific parameter optimization from precursors and substrate design to the adjusting of growth parameters(temperature and pressure).Meanwhile,we present other strategies to produce various kinds of wafer-scale 2D materials.Finally,we conclude the current challenges and future directions in this developing field.This work may inspire researchers to better design routes in the synthesis of wafer-scale 2D materials with high quality. | Xin Tong Keli Liu Mengqi Zeng Lei Fu | 2019 | InfoMat2019,1,4: | 5 |
| 5 | High flux photocatalytic self-cleaning nanosheet C_(3)N_(4) membrane supported by cellulose nanofibers for dye wastewater purification显示文摘Hazardous dye substances discharged from the textile and dyestuff industries not only threaten local the surrounding ecosystems but are also hard to degraded.We report the preparation of process for a photocatalytic membrane device that can degrade dye pollution under visible light.This filtration membrane,with a well-organized multilayer structure,simultaneously achieves continuous and flow-through separation of degradation products.Cellulose nanofibers(CNFs)were used as a template for nanosheet C_(3)N_(4)(NS C_(3)N_(4))preparation;the performance for the photocatalytic degradation of dyes improved as the morphology changed from bulking to nanosheet.NS C3N4 was then attached to the surface of a prepared CNF membrane via vacuum filtration.This device exhibited high efficiency(the degradation rates of both Rhodamine B and Methylene blue both reached 96%),high flux(above 160 L·h^(-1)·m^(-2)·bar^(-1))and excellent stability(maintaining steady flux and high separation were maintained after 4 h).This easy-preparation,easy-scale-up,and low-cost process provides a new method of fabricating photocatalytic membrane devices for dye wastewater treatment. | Lilong Zhang Ge Meng Guifang Fan Keli Chen Yulong Wu Jian Liu | 2021 | Nano Research2021,14,8: | 3 |
| 6 | Progress in octahedral spherical hohlraum study显示文摘In this paper,we give a review of our theoretical and experimental progress in octahedral spherical hohlraum study.From our theoretical study,the octahedral spherical hohlraums with 6 Laser Entrance Holes(LEHs)of octahedral symmetry have robust high symmetry during the capsule implosion at hohlraum-to-capsule radius ratio larger than 3.7.In addition,the octahedral spherical hohlraums also have potential superiority on low backscattering without supplementary technology.We studied the laser arrangement and constraints of the octahedral spherical hohlraums,and gave a design on the laser arrangement for ignition octahedral hohlraums.As a result,the injection angle of laser beams of 50°-60°was proposed as the optimum candidate range for the octahedral spherical hohlraums.We proposed a novel octahedral spherical hohlraum with cylindrical LEHs and LEH shields,in order to increase the laser coupling efficiency and improve the capsule symmetry and to mitigate the influence of the wall blowoff on laser transport.We studied on the sensitivity of the octahedral spherical hohlraums to random errors and compared the sensitivity among the octahedral spherical hohlraums,the rugby hohlraums and the cylindrical hohlraums,and the results show that the octahedral spherical hohlraums are robust to these random errors while the cylindrical hohlraums are the most sensitive.Up till to now,we have carried out three experiments on the spherical hohlraum with 2 LEHs on Shenguang(SG)laser facilities,including demonstration of improving laser transport by using the cylindrical LEHs in the spherical hohlraums,spherical hohlraum energetics on the SGIII prototype laser facility,and comparisons of laser plasma instabilities between the spherical hohlraums and the cylindrical hohlraums on the SGIII laser facility. | Ke Lan Jie Liu Zhichao Li Xufei Xie Wenyi Huo Yaohua Chen Guoli Ren Chunyang Zheng Dong Yang Sanwei Li Zhiwen Yang Liang Guo Shu Li Mingyu Zhang Xiaoying Han Chuanlei Zhai Lifei Hou Yukun Li Keli Deng Zheng Yuan Xiayu Zhan Feng Wang Guanghui Yuan Haijun Zhang Bobin Jiang Lizhen Huang Wei Zhang Kai Du Runchang Zhao Ping Li Wei Wang Jingqin Su Xuewei Deng Dongxia Hu Wei Zhou Huaiting Jia Yongkun Ding Wanguo Zheng Xiantu He | 2016 | Matter and Radiation at Extremes2016,1,1: | 2 |
| 7 | Active Vaccine Safety Surveillance: Global Trends and Challenges in China显示文摘Importance.The great success in vaccine-preventable diseases has been accompanied by vaccine safety concerns.This has caused vaccine hesitancy to be the top 10 in threats to global health.The comprehensive understanding of adverse events following immunization should be entirely based on clinical trials and postapproval surveillance.It has increasingly been recognized worldwide that the active surveillance of vaccine safety should be an essential part of immunization programs due to its complementary advantages to passive surveillance and clinical trials.Highlights.In the present study,the framework of vaccine safety surveillance was summarized to illustrate the importance of active surveillance and address vaccine hesitancy or safety concerns.Then,the global progress of active surveillance systems was reviewed,mainly focusing on population-based or hospital-based active surveillance.With these successful paradigms,the practical and reliable ways to create robust and similar systems in China were discussed and presented from the perspective of available databases,methodology challenges,policy supports,and ethical considerations.Conclusion.In the inevitable trend of the global vaccine safety ecosystem,the establishment of an active surveillance system for vaccine safety in China is urgent and feasible.This process can be accelerated with the consensus and cooperation of regulatory departments,research institutions,and data owners. | Zhike Liu Ruogu Meng Yu Yang Keli Li Zundong Yin Jingtian Ren Chuanyong Shen Zijian Feng Siyan Zhan | 2021 | Health Data Science2021,,1: | 2 |

| 9 | The effect of hydrogen-bond in alcoholic solvent on the solvation ultrafast dynamics of oxazine 750 dye显示文摘The ultrafast dynamics of oxazine 750 dye was studied in methanol,ethanol,1-propanol,1-butanol solvents using the femtosecond time-resolved stimulated emission pumping fluorescence depletion (FS TR SEP FD) technique. The faster decays on the hundreds of femtosecond time scale and the slower decays on the order of picosecond were found. The intramolecular vibrational redistribution (IVR) and the solute-solvent intermolecular photoinduced electron transfer (ET) should account for the faster decay,while the slower decay is attributable to the diffusive solvent relaxation. The results show that the intermolecular hydrogen-bonding network will hinder the rearrangement of the alcoholic molecules in the solvation process and the time constants of the slower diffusive solvent relaxation decays are found to increase with the hydrogen-bonding energy in alcoholic solvents. | ZHOU LiChuan SHI Ying LIU JianYong HAN KeLi | 2008 | Chinese Science Bulletin2008,53,13: | 2 |
| 10 | Doped all-inorganic cesium zirconium halide perovskites with high-efficiency and tunable emission显示文摘Doping enables manipulation of both the electrical and optical properties of halide perovskites.Herein,we incorporated Te^(4+) into Cs_(2)ZrCl_(6) single crystal,simultaneously preserving the vacancy-ordered structure,to obtain an efficient yellow-emitting perovskite with a near-unity photoluminescence quantum yield(PLQY≈97.6%).Te^(4+) doping modifies the hue and emission color of pristine Cs_(2)ZrCl_(6),generates new absorption channels,and successfully extends the excitation energy from<280 nm to 360-450 nm range.Detailed spectral characterizations,including ultrafast femtosecond transient absorption measurements,reveal that the bright yellow light is derived from triplet self-trapped excitons.Moreover,further tuning doping concentration enables Te-doped Cs_(2)ZrCl_(6) single crystals to exhibit efficient warm white light emission.This work provides a new perspective for the development and design of stable lead-free perovskites with highly efficient luminescence. | Pengfei Cheng Daoyuan Zheng Lu Feng Yuefeng Liu Junxue Liu Juntao Li Yang Yang Guoxiong Wang Keli Han | 2022 | Journal of Energy Chemistry2022,31,2: | 2 |

| 15 | Explicit solvent model for spectral shift of acrolein and simulation with molecular dynamics显示文摘By introducing the concept of spring energy of permanent dipole and taking the conforma-tions of solvent molecules into account,the formulas of electrostatic solvation energy in equilibrium and nonequilibrium are derived from the explicit solvent scheme,with the spatial distribution of the discrete permanent charges and induced dipoles of the sol-vent molecules involved. The energy change of sol-ute due to the variation of wave function from the case of vacuum to that in solution is estimated by treating the solvent effect as external field in the it-eration cycles of the self-consistent field. The ex-pression for spectral shift is deduced and applied to the processes of light absorption and emission in solution. According to the new formulations,the av-eraged solvent electrostatic potential/molecular dy-namics program is modified and adopted to investi-gate the equilibrium solvation energy of water mole-cule and spectral shift of acrolein. | ZHU Quan LIU Jifeng FU Kexiang HAN Keli LI Xiangyuan | 2006 | Chinese Science Bulletin2006,51,24: | 1 |

| 17 | Quantifying the Influences of Carbides and Porosities on the Fatigue Crack Evolution of a Ni-Based Single-Crystal Superalloy using X-ray Tomography显示文摘The detrimental effects of carbides and porosity on the fatigue crack initiation and propagation of nickel-based single-crystal superalloys have been reported by many previous studies.However,few studies have quantitatively compared the fatigue damaging effects of carbides and pores on the fatigue crack evolution.In this study,a high-resolution X-ray computed tomography(XCT)characterization of a DD5 nickel-based single-crystal superalloy during fatigue test was performed.The evolution of carbides,pores and cracks at all stages was observed and tracked.In order to quantify the 3D microstructures,a new damage factor that correlates the morphology of fracture surface with crack evolution behaviors was proposed.It was found that porosity was more detrimental than carbides in crack initiation and propagation during fatigue tests.Furthermore,pore spacing has been found to be the most significant factor among all controlling pore characteristics in the crack initiation stage and sphericity is the most critical pore characteristic in the crack propagation stage.Therefore,by statistically analyzing the evolution of carbides and pores during fatigue tests in this study,the underlying fatigue cracking mechanism of nickel-based superalloys is revealed. | Keli Liu Junsheng Wang Bing Wang Pengcheng Mao Yanhong Yang Yizhou Zhou | 2022 | Acta Metallurgica Sinica(English Letters)2022,35,1: | 1 |
