| 1 | Special Section:SARS-CoV-2 Preliminary evidence from a multicenter prospective observational study of the safety and efficacy of chloroquine for the treatment of COVID-19显示文摘Effective therapies are urgently needed for the SARS-CoV-2 pandemic.Chloroquine has been proved to have antiviral effect against coronavirus in vitro.In this study,we aimed to assess the efficacy and safety of chloroquine with different doses in COVID-19.In this multicenter prospective observational study,we enrolled patients older than 18 years old with confirmed SARS-CoV-2 infection excluding critical cases from 12 hospitals in Guangdong and Hubei Provinces.Eligible patients received chloroquinephosphate s00 mg,orally,once(half dose)or twice(full dose)daily.Patients treated with non-chloroquine therapy were included as historical controls.The primary endpoint is the time to undetectable viral RNA.Secondary outcomes include the proportion of patients with undetectable viral RNA by day 10 and 14,hospitalization time,duration of fever,and adverse events.A total of 197 patients completed chloroquine treatment,and 176patients were included as historical controls.The median time to achieve an undetectable viral RNA was shorter in chloroquine than in non-chloroquine(absolute difference in medians-6.0 days;95%CI-6.0 to—4.0).The duration of fever is shorter in chloroquine(geometric mean ratio 0.6;95%CIO.5 to 0.8).No serious adverse events were observed in the chloroquine group.Patients treated with half dose experienced lower rate of adverse events than with full dose.Although randomized trials are needed for further evaluation,this study provides evidence for safety and efficacy of chloroquine in COVID-19 and suggests that chloroquine can be a cost-effective therapy for combating the COVID-19 pandemic. | Mingxing Huang Man Li Fei Xiao Pengfei Pang Jiabi Liang Tiantian Tang Shaoxuan Liu Binghui Chen Jingxian Shu Yingying You Yang Li Meiwen Tang Jianhui Zhou Guanmin Jiang Jingfen Xiang Wenxin Hong Songmei He Zhaoqin Wang Jianhua Feng Changqing Lin Yinong Ye Zhilong Wu Yaocai Li Bei Zhong Ruilin Sun Zhongsi Hong Jing Liu Huili Chen Xiaohua Wang Zhonghe Li Duanqing Pei Lin Tian Jinyu Xia Shanping Jiang Nanshan Zhong Hong Shan | 2020 | National Science Review2020，7，9： | 20 |
| 2 | A potential red-emitting phosphor Ca_(2)YTaO_(6):Eu^(3+):Luminescence properties,thermal stability and applications for white LEDs显示文摘A novel red-emitting phosphor tantalate Ca_(2)YTaO_(6):Eu^(3+)was synthesized by a solid-state reaction.The purity and surface morphology of the phosphors were characterized.The Ca_(2)YTaO_(6):Eu^(3+)phosphors show a sharp emission peak at 612 nm under near-ultraviolet(n-UV) at 395 nm because of the ^(5)D0→^(7)F_(2) transition of Eu^(3+).The optimal Eu^(3+)doping concentration in Ca_(2)YTaO_(6) is 40 mol% and the critical energy-transfer distance of Eu^(3+)ions was calculated to be 0.9 nm.The emission spectra of Ca_(2)YTaO_(6):Eu_(3+)from 300 to 480 K were investigated.The thermal-quenching temperature(T_(0.5)) of Ca_(2)YTaO_(6):Eu^(3+)is above 480 K.The color purity of Ca_(2)YTaO_(6):40 mol%Eu^(3+)is as high as 99.8%.The luminescence lifetime of Ca_(2)YTaO_(6):40 mol%Eu^(3+)was also discussed.The high color purity and high thermal stability of Eu^(3+)-doped Ca_(2)YTaO_(6) phosphors contribute to its application value in white lightemitting diodes(w-LEDs). | Ka Ding Siru A Shuo Pang Leyan Shan Yaqi Zhang Pengfei Sun Bin Deng Ruijin Yu | 2021 | Journal of Rare Earths2021，39，7： | 4 |
| 3 | Active and stable Cu doped NiMgAlO catalysts for upgrading ethanol to n-butanol显示文摘Upgrading ethanol to n-butanol is an attractive way for renewable n-butanol production. Herein, Cu was selected to modify NiMgAlO catalysts for improving ethanol conversion and n-butanol selectivity. Over the optimized 2%Cu-NiMgAlO catalyst, ethanol conversion and n-butanol selectivity were enhanced to 30.0% and 64.2%, respectively, in 200 h time on stream at 523 K. According to physicochemical characterizations and theoretical calculations, the key role of multiple active sites in this reaction was extensively investigated. The plate-like structure of hydrotalcite was maintained over 2%Cu-NiMgAlO catalysts, with an average Ni particle size of ca. 5.4 nm. The presence of Cu species created CuNi alloy sites and Lewis acid-base pairs, and increased hydrogen transfer and condensation reactions, resulting in elevated ethanol conversion and n-butanol selectivity. Additionally, CuNi alloy had a strong interaction with CuNiMgAl oxides, forming homogeneous boundary due to their close ionic radius and lattice matching, and afforded the long time stability in the ethanol to n-butanol reaction. | Zhinuo Wang Ming Yin Jifeng Pang Xianquan Li Yanan Xing Yang Su Shimin Liu Xiaoyan Liu Pengfei Wu Mingyuan Zheng Tao Zhang | 2022 | Journal of Energy Chemistry2022，31，9： | 2 |
| 4 | NiCo_(2)S_(4)/N microspheres grown on N,S co-doped reduced graphene oxide as an efficient bifunctional electrocatalyst for overall water splitting in alkaline and neutral pH显示文摘It is of vital importance to design efficient and low-cost bifunctional catalysts for the electrochemical water splitting under alkaline and neutral pH conditions.In this work,we report an efficient and stable NiCo_(2)S_(4)/N,S co-doped reduced graphene oxide(NCS/NS-rGO)electrocatalyst for water splitting,in which NCS microspheres are composed of one-dimentional(1D)nanorods grown homogeneously on the surface of NS-rGOs).The synergetic effect,abundant active sites,and hybridization of NCS/NS-rGO endow their outstanding electrocatalytic performance for hydrogen evolution reaction(HER)and oxygen evolution reaction(OER)in both alkaline and neutral conditions.Furthermore,NCS/NS-rGO employed as both anode and cathode in a two-electrode alkaline and neutral system electrolyzers deliver 10 mA/cm^(2) with the low cell voltage of 1.58 V in alkaline and 1.91 V in neutral condition.These results illustrate the rational design of carbon-supported nickel-cobalt based bifunctional materials for practical water splitting over a wide pH range. | Haoquan Li Long Chen Pengfei Jin Yafei Li Jianxiang Pang Juan Hou Shanglong Peng Gang Wang Yulin Shi | 2022 | Nano Research2022，15，2： | 1 |

| 7 | Treating COVID-19 with Chloroquine显示文摘A novel coronavirus disease 2019(COVID-19)emerged around December 2019 in Wuhan,China and has spread rapidly worldwide(Lu et al.,2020).Until March 27,2020,the Chinese health authorities had reported 82082 confirmed COVID-19 cases in China with 3298 deaths and 381443 confirmed cases with 20787 deaths outside China.The World Health Organization(WHO)named the virus SARS-CoV-2,which belongs to a distinct clade from the human severe acute respiratory syndrome CoV(SARS-CoV)and Middle East respiratory syndrome CoV(MERSCoV)(Zhu et al.,2020). | Mingxing Huang Tiantian Tang Pengfei Pang Man Li Ruolan Ma Jiahui Lu Jingxian Shu Yingying You Binghui Chen Jiabi Liang Zhongsi Hong Huili Chen Ling Kong Dajiang Qin Duanqing Pei Jinyu Xia Shanping jiang Hong Shan | 2020 | Journal of Molecular Cell Biology2020，12，4： | 1 |
| 8 | Improved stability of superelasticity and elastocaloric effect in Ti-Ni alloys by suppressing Lüders-like deformation under tensile load显示文摘Functional stability of superelasticity is crucial for practical applications of shape memory alloys.It is degraded by a Lüders-like deformation with elevated local stress concentration under tensile load.By increasing the degree of solute supersaturation and applying appropriate thermomechanical treatments,a Ti-Ni alloy with nanocrystallinity and dispersed nanoprecipitates is obtained.In contrast to conventional Ti-Ni alloys,the superelasticity in the target alloy is accompanied by homogeneous deformation due to the sluggish stress-induced martensitic transformation.The alloy thus shows a fully recoverable strain of 6%under tensile stress over 1 GPa and a large adiabatic temperature decrease of 13.1 K under tensile strain of 4.5%at room temperature.Moreover,both superelasticity and elastocaloric effect exhibit negligible degradation in response to applied strain of 4%during cycling.We attribute the improved functional stability to low dislocation activity resulting from the suppression of localized deformation and the combined strengthening effect of nanocrystalline structure and nanoprecipitates.Thus,the design of such a microstructure enabling homogeneous deformation provides a recipe for stable superelasticity and elastocaloric effect. | Pengfei Dang Jianbo Pang Yumei Zhou Lei Ding Lei Zhang Xiangdong Ding Turab Lookman Jun Sun Dezhen Xue | 2023 | Journal of Materials Science & Technology2023，，15： | 1 |

| 10 | MEMS ultrasonic transducers for safe,low-power and portable eye-blinking monitoring显示文摘Eye blinking is closely related to human physiology and psychology.It is an effective method of communication among people and can be used in human-machine interactions.Existing blink monitoring methods include videooculography,electro-oculograms and infrared oculography.However,these methods suffer from uncomfortable use,safety risks,limited reliability in strong light or dark environments,and infringed informational security.In this paper,we propose an ultrasound-based portable approach for eye-blinking activity monitoring.Low-power pulse-echo ultrasound featuring biosafety is transmitted and received by microelectromechanical system(MEMS)ultrasonic transducers seamlessly integrated on glasses.The size,weight and power consumption of the transducers are 2.5 mm by 2.5 mm,23.3 mg and 71μW,respectively,which provides better portability than conventional methods using wearable devices.Eye-blinking activities were characterized by open and closed eye states and validated by experiments on dfferent volunteers.Finally,real-time eye-blinking monitoring was successfully demonstrated with a response time less than 1 ms.The proposed solution paves the way for ultrasound-based wearable eye-blinking monitoring and offers miniaturization,light weight,low power consumption,high informational security and biosafety. | Sheng Sun Jianyuan Wang Menglun Zhang Yuan Ning Dong Ma Yi Yuan Pengfei Niu Zhicong Rong Zhuochen Wang Wei Pang | 2022 | Microsystems & Nanoengineering2022，8，3： | 0 |
| 11 | Development of the magnetic separation device for surface cracks of delinted cottonseed显示文摘In seed processing for commercial production,the collision or friction between mechanical parts and seed is inevitable.These collisions or friction can cause cracks on the surface of the seed,which can affect germination rates and ultimately reduce crop yields.Using the difference of the seed motion trajectories with different crack degrees in the magnetic field,the grading of the surface crack seed can be realized.In this study,the motion law of seed in a non-uniform magnetic field was analyzed by taking the delinted cottonseed as an object.A magnetic separation device for crop seeds was developed.This device was essentially composed of the feed throat,magnetic roller,conveyor belt,and variable-frequency adjustable-speed motor.The magnetic powder adhering seeds enter the magnetic separation device through the feed throat and are conveyed to the magnetic roller through the conveyor belt.The magnetic roller has different adsorption forces on seeds with different degrees of cracking,and seeds fall into different outlets,thus completing the grading of the seeds.By adjusting working parameters such as the magnetic field strength and the speed of the conveyor belt,magnetic separation could be made.In order to verify the grading effect,the magnetic separation accuracy was taken as the inspection index,the magnetic powder’s mesh number,the mass mixing ratio between magnetic powder and delinted cottonseed,and the rotation speed of the magnetic roller were taken as the inspection factors.The response surface methodology was used to optimize the working parameters of the experimental device.The results showed that the optimal process parameters of the magnetic separation device were as follows:the number of magnetic powder meshes was 250,the mass mixing ratio between magnetic powder and delinted cottonseed was 1:20,and when the rotational speed of the magnetic separation roller was 20 r/min,the detection rate reached 92.5%.The designed magnetic separation device can realize the non-destructive batch detection of seed surface cracks with high work efficiency and has guiding significance for the high-precision and low-damage classification detection and classification of commercial seed. | Xinwu Du Guodong Wang Jing Pang Pengfei Li Xin Jin Wenhua Mao | 2023 | International Journal of Agricultural and Biological Engineering2023，16，6： | 0 |
| 12 | Electrode design for multimode suppression of aluminum nitride tuning fork resonators显示文摘This paper is focused on electrode design for piezoelectric tuning fork resonators.The relationship between the performance and electrode pattern of aluminum nitride piezoelectric tuning fork resonators vibrating in the in-plane flexural mode is investigated based on a set of resonators with different electrode lengths,widths,and ratios.Experimental and simulation results show that the electrode design impacts greatly the multimode effect induced from torsional modes but has little influence on other loss mechanisms.Optimizing the electrode design suppresses the torsional mode successfully,thereby increasing the ratio of impedance at parallel and series resonant frequencies(R_(p)/R_(s))by more than 80%and achieving a quality factor(Q)of 7753,an effective electromechanical coupling coefficient(kt_(eff)^(2))of 0.066%,and an impedance at series resonant frequency(R_(m))of 23.6 kΩ.The proposed approach shows great potential for high-performance piezoelectric resonators,which are likely to be fundamental building blocks for sensors with high sensitivity and low noise and power consumption. | Yi Yuan Qingrui Yang Haolin Li Shuai Shi Pengfei Niu Chongling Sun Bohua Liu Menglun Zhang Wei Pang | 2023 | Nanotechnology and Precision Engineering2023，6，4： | 0 |
| 13 | SER performance investigation of UWOC system over composite EGG oceanic turbulence fading channel with BSF显示文摘In this work,the symbol error rate(SER) performance of a relay-assisted underwater wireless optical communication(UWOC) system has been investigated over the composite exponential-generalized gamma(EGG) distribution with the beam spread function(BSF) under two hard decision schemes of fixed decision threshold(FDT) and dynamic decision threshold(DDT).Specifically,the oceanic turbulence is assumed to follow the EGG distribution,and the impacts of absorption,scattering and misalignment loss are characterized by BSF.The cumulative distribution function(CDF) of this UWOC system is derived with the max-min criterion as the best path selection scheme.And with the help of Gauss-Laguerre quadrature function,the analytical SER expressions for these two threshold schemes are then achieved and validated by Monte Carlo(MC) simulation.Moreover,the SER performance is further studied under different temperature gradients,bubble levels(BLs) and water salinity over three water types,as well as the system structure parameters.Results show that the UWOC system with DDT scheme can efficiently overcome the error floor induced by FDT scheme and demonstrates better SER performance.Furthermore,the SER performance would be improved with lower BL,temperature gradients and water salinity as well as the concentration of dissolved particles.This work will benefit the design and research of relay-assisted UWOC system. | YANG Pengfei PANG Weina LI Shuang WANG Ping CHEN Wenwen CHE Hui | 2022 | Optoelectronics Letters2022，18，10： | 0 |
| 14 | Systematic evaluation of IgG responses to SARS-CoV-2 spike protein-derived peptides for monitoring COVID-19 patients显示文摘Serological tests play an essential role in monitoring and combating the COVID-19 pandemic.Recombinant spike protein(S protein),especially the S1 protein,is one of the major reagents used for serological tests.However,the high cost of S protein production and possible cross-reactivity with other human coronaviruses pose unavoidable challenges.By taking advantage of a peptide microarray with full spike protein coverage,we analyzed 2,434 sera from 858 COVID-19 patients,63 asymptomatic patients and 610 controls collected from multiple clinical centers.Based on the results,we identified several S protein-derived 12-mer peptides that have high diagnostic performance.In particular,for monitoring the IgG response,one peptide(aa 1148-1159 or S2-78)exhibited a sensitivity(95.5%,95%CI 93.7-96.9%)and specificity(96.7%,95%CI 94.8-98.0%)comparable to those of the S1 protein for the detection of both symptomatic and asymptomatic COVID-19 cases.Furthermore,the diagnostic performance of the S2-78(aa 1148-1159)IgG was successfully validated by ELISA in an independent sample cohort.A panel of four peptides,S1-93(aa 553-564),S1-97(aa 577-588),S1-101(aa 601-612)and S1-105(aa 625-636),that likely will avoid potential cross-reactivity with sera from patients infected by other coronaviruses was constructed.The peptides identified in this study may be applied independently or in combination with the S1 protein for accurate,affordable,and accessible COVID-19 diagnosis. | Yang Li Dan-yun La Qing Lei Zhao-wei Xu Feng Wang Hongyan Hou Lingyun Chen Jiaoxiang Wu Yan Ren Ming-liang Ma Bo Zhang Hong Chen Caizheng Yu Jun-biao Xue Yun-xiao Zheng Xue-ning Wang He-wei Jiang Hai-nan Zhang Huan Qi Shu-juan Guo Yandi Zhang Xiaosong Lin Zongjie Yao Pengfei Pang Dawei Shi Wei Wang Xiao Yang Jie Zhou Huiming Sheng Ziyong Sun Hong Shan Xionglin Fan Sheng-ce Tao | 2021 | Cellular & Molecular Immunology2021，18，3： | 0 |

Their structures were elucidated on the basis of spectroscopic data(NMR, UV, IR, and MS). Compound 1 represents the first example of cis clerodane-type diterpene in the plants of Leonurus genus. Compounds 1 and 4 exhibited weak inhibition of nitric oxide production in lipopolysaccharide-stimulated BV-2 microglial cells with IC_(50) values of 35.8 ± 3.6 mmol/L and 48.6 ± 4.8 mmol/L, | Yunfang Zhao Zheng Huang Jing Sun Daoran Pang Xiaonan Chen Huina Yao Zhixiang Zhu Jiao Zheng Pengfei Tu Jun Li | 2019 | Chinese Chemical Letters2019，30，1： | 0 |
| 16 | Microstructure and mechanical properties stability of pre-hardening treatment in Al-Cu alloys for pre-hardening forming process显示文摘The stability of the microstructure and mechanical properties of the pre-hardened sheets during the pre-hardening forming(PHF)process directly determines the quality of the formed components.The microstructure stability of the pre-hardened sheets was in-vestigated by differential scanning calorimetry(DSC),transmission electron microscopy(TEM),and small angle X-ray scattering(SAXS),while the mechanical properties and formability were analyzed through uniaxial tensile tests and formability tests.The results in-dicate that the mechanical properties of the pre-hardened alloys exhibited negligible changes after experiencing 1-month natural aging(NA).The deviations of ultimate tensile strength(UTS),yield strength(YS),and sheet formability(Erichsen value)are all less than 2%.Also,after different NA time(from 48 h to 1 month)is applied to alloys before pre-hardening treatment,the pre-hardened alloys possess stable microstructure and mechanical properties as well.Interestingly,with the extension of NA time before pre-hardening treatment from 48 h to 1 month,the contribution of NA to the pre-hardening treatment is limited.Only a yield strength increment of 20 MPa is achieved,with no loss in elongation.The limited enhancement is mainly attributed to the fact that only a limited number of clusters are transformed into Guinier-Preston(GP)zones at the early stage of pre-hardening treatment,and the formation ofθ''phase inhibits the nucleation and growth of GP zones as the precipitated phase evolves. | Liping Tang Pengfei Wei Zhili Hu Qiu Pang | 2024 | International Journal of Minerals,Metallurgy and Materials2024，31，3： | 0 |
| 17 | ZmMYC7 directly regulates ZmERF147 to increase maize resistance to Fusarium graminearum显示文摘The jasmonic acid(JA)signaling pathway is involved in plant growth,development,and response to abiotic or biotic stresses.MYC2,a bHLH transcription factor,is a regulatory hub in the pathway.The function of ZmMYC7,a putative MYC2 ortholog,in jasmonate-signaled defense responses of maize has not been reported.In this study,we found that ZmMYC7 possesses JID,TAD,bHLH and Zip domains and essential characteristics of transcription factors:a nuclear location and transactivation activity.The ZmMYC7mutants showed markedly increased sensitivity to Fusarium graminearum and Setosphaeria turcica.The expression levels of the defense-associated genes ZmPR1,ZmPR2,ZmPR3,ZmPR5,ZmPR6,and ZmPR7 in response to F.graminearum infection were downregulated in ZmMYC7 mutants,while ZmPR4 and ZmPR10 were up-regulated.ZmMYC7 interacted with members of the ZmJAZ family,including ZmJAZ8,ZmJAZ11,and ZmJAZ12.ZmMYC7 physically interacted with G-box cis-elements in the ZmERF147 promoter in vitro and transcriptional activation of ZmERF147 by ZmMYC7 was inhibited by ZmJAZ11 and ZmJAZ12.ZmERF147 mutants were more susceptible to F.graminearum infection than inbred line B73with concomitant down-regulation of all defense-associated ZmPRs except ZmPR4.These findings indicate that ZmMYC7 functions in maize resistance to F.graminearum and sheds light on maize defense responses to pathogenic fungi via the JA signaling pathway. | Hongzhe Cao Kang Zhang Wei Li Xi Pang Pengfei Liu Helong Si Jinping Zang Jihong Xing Jingao Dong | 2023 | The Crop Journal2023，11，1： | 0 |
| 18 | Synthesis and properties of binaphthyl chiral thermally activated delayed fluorescence molecules using thioxanthone as acceptor显示文摘The currently reported axial chiral molecules based on the 3,3'-substitution of the binaphthyl skeleton are limited by intrinsic fluorescence properties,resulting in generally low device efficiencies(EQE<5%)of related organic light emitting diodes(OLEDs).Herein,we designed and synthesized four pair of chiral binaphthyl enantiomers(R/S-1-R/S-4)adopting acceptor-donor-donor-acceptor(ADDA)structure by introducing different thioxanthone modification groups on the 3,3'-position of 2,2'-dimethoxy-1,1'-binaphthalene.Among them,emitter R/S-2 and R/S-4 obtained by enhancing intramolecular charge transfer exhibited TADF characteristics due to relatively small Est of 0.12eV and 0.17eV,and relatively moderate SOC matrix elements of 0.28 cm^(-1)and 0.10 cm^(-1)between the 1CT and 3LE states.The CD spectra of these enantiomers in diluted solutions showed perfect mirror images and reasonable gabs for small organic molecules(10^(-4)-10^(-3)).And the external quantum eficiencies(EQE)of 10.9%and 8.32%for device A and B based on emitter S-2 and S-4 were highest compared with currently reported axial chiral molecules based on the 3,3'-position substitution of binaphthyl skeleton,providing simple molecular design strategies to construct efficient CP-OLED device. | Xiangyu Dong Shaogang Shen Yuanyuan Qin Xiaoxiao Hu Honglei Gao Guanhao Liu Teng Ga Zhi Pang Pengfei Wang Ying Wang | 2023 | Chinese Chemical Letters2023，34，12： | 0 |
| 19 | Algorithm to identify circulating tumor cell clusters using in vivo flow cytometer显示文摘Recent studies in oncology have addressed the importance of detecting circulating tumor cell clusters because circulating tumor cell clusters might survive and metastasize more easily than single circulating tumor cells.Signals with larger peak widths detected by in vivo flow cytometer(IVFC)have been used to identify cell clusters in previous studies.However,the accuracy of this criterion might be greatly degraded by variance in blood°ow and the rolling behaviors of circulating tumor cells.Here,we propose a criterion and algorithm to distinguish cell clusters from single cells.In this work,we first used area-based and volume-based models for single°uorescent cells.Simulating each model,we analyzed the corresponding morphology of IVFC signals from cell clusters.According to the Rayleigh criterion,the valley between two adjacent peak signals from two distinguishable cells should be lower than 73.5%of the peak values.A novel signal processing algorithm for IVFC was developed based on this criterion.The results showed that cell clusters can be reliably identied using our proposed algorithm.Intravital imaging was also performed to further support our algorithm.With enhanced accuracy,IVFC is a powerful tool to study circulating cell clusters. | Kai Pang Dan Wei Pengfei Hai Zhangru Yang Xiaofu Weng Xunbin Wei | 2018 | Journal of Innovative Optical Health Sciences2018，，5： | 0 |
| 20 | Ti_(3)AlC_(2)材料辐照后空位型缺陷的演化显示文摘MAX phase material is a layered ternary compound with the chemical formula Mn+1AXn.M represents the transition metal the A represents A-group element and X is the nitrogen or carbon.We take Ti_(3)AlC_(2) as the sample.This material exhibits a combination of the attributes of both metals and ceramics[1].As a result,it has been considered as potential materials for use in current and future nuclear applications.Numerous researches have been focused on the phase transformation progress and anti-amorphization trait of this material[2,3].However,few researches have reported the behavior of vacancy defects after irradiation.We use the PAT and DBS technique to investigate this issue and try to find the relationship among the density of vacancy type defects,phase transformation,the irradiation fluence and temperature. | Deng Tianyu Sun Jianrong Wang Zhiguang Pang Lilong Shen Tielong Zhu Yabin Cui Minghuan Tai Pengfei | 2018 | IMP & HIRFL Annual Report2018，，1： | 0 |
