| 2 | Comparison of the toxicity of silver nanoparticles and silver ions on the growth of terrestrial plant model Arabidopsis thaliana显示文摘Silver nanoparticles (AgNPs) are one of the most widely used nanomaterials, but the mechanism of AgNP toxicity in terrestrial plants is still unclear. We compared the toxic effects of AgNPs and Ag+ on Arabidopsis thaliana at the physiological, ultrastructural and molecular levels. AgNPs did not affect seed germination; however, they showed stronger inhibitory effect on root elongation than Ag+ . The results of transmission electron microscopy and metal content analysis showed that AgNPs could be accumulated in leaves. These absorbed AgNPs disrupted the thylakoid membrane structure and decreased chlorophyll content, which can inhibit plant growth. By comparison, a small amount of Ag+ was absorbed by seedlings, and it did not pronouncedly affect chloroplast structure and other metal ion absorption as AgNPs did. Compared with Ag+ , AgNPs could alter the transcription of antioxidant and aquaporin genes, indicating that AgNPs changed the balance between the oxidant and antioxidant systems, and also affected the homeostasis of water and other small molecules within the plant body. All the data from physiological, ultrastructural and molecular levels suggest that AgNPs were more toxic than Ag+ . | Haifeng Qian Xiaofeng Peng Xiao Han Jie Ren Liwei Sun Zhengwei Fu | 2013 | Journal of Environmental Sciences2013,25,9: | 14 |
| 3 | Characteristics of Cd isotopic compositions and their genetic significance in the lead-zinc deposits of SW China显示文摘Up to now,the evaporation and condensation,as well as the biological absorption and inorganic absorptions,have been proved to be major factors in Cd isotope fractionation.And Cd isotopes have been widely applied in studies on the universal evolution and marine environment and so on.However,only a few researches have been conducted in applying Cd isotopes to trace the source of metallogenic material and the evolution of the ore-forming fluid in a complex mineralization environment,especially in a hydrothermal ore-formation system.We measured the Cd isotopic compositions of sphalerite,galena,and ores from five lead-zinc deposits in SW China,and found that the 114/110Cd values varied from 1.53‰to 0.34‰,with a total range of1.87‰,which is greater than most of measured geological samples.Meanwhile,through contrasting the Cd content with Cd isotopic compositions of different deposits,it may be concluded that different genetic lead-zinc deposits have different Cd content and isotopic compositions,which could be a tool for the studies on the origin of ore deposits.Also,the biomineralization and crystal fractionation may also result in Cd isotope fractionation.In a word,although the research of Cd isotopes is presently at the preliminary stage(especially in hydrothermal ore-formation system),this study demonstrated that Cd isotopes can give a clue in tracing the evolution of ore-forming fluid and metallogenic environment. | ZHU ChuanWei WEN HanJie ZHANG YuXu FAN HaiFeng FU ShaoHong XU Juan QIN TingRong | 2013 | Science China Earth Sciences2013,56,12: | 14 |

| 6 | Diclofop-methyl affects microbial rhizosphere community and induces systemic acquired resistance in rice显示文摘Diclofop-methyl(DM),a widely used herbicide in food crops,may partly contaminate the soil surface of natural ecosystems in agricultural area and exert toxic effects at low dose to nontarget plants.Even though rhizosphere microorganisms strongly interact with root cells,little is known regarding their potential modulating effect on herbicide toxicity in plants.Here we exposed rice seedlings(Xiushui 63) to 100 μg/L DM for 2 to 8 days and studied the effects of DM on rice rhizosphere microorganisms,rice systemic acquired resistance(SAR) and rice-microorganisms interactions.The results of metagenomic 16 S rDNA Illumina tags show that DM increases bacterial biomass and affects their community structure in the rice rhizosphere.After DM treatment,the relative abundance of the bacterium genera Massilia and Anderseniella increased the most relative to the control.In parallel,malate and oxalate exudation by rice roots increased,potentially acting as a carbon source for several rhizosphere bacteria.Transcriptomic analyses suggest that DM induced SAR in rice seedlings through the salicylic acid(but not the jasmonic acid) signal pathway.This response to DM stress conferred resistance to infection by a pathogenic bacterium,but was not influenced by the presence of bacteria in the rhizosphere since SAR transcripts did not change significantly in xenic and axenic plant roots exposed to DM.The present study provides new insights on the response of rice and its associated microorganisms to DM stress. | Si Chen Xingxing Li Michel Lavoie Yujian Jin Jiahui Xu Zhengwei Fu Haifeng Qian | 2017 | Journal of Environmental Sciences2017,29,1: | 8 |

| 11 | X-ray pulsar-based navigation using pulse phase and Doppler frequency measurements显示文摘In order to eliminate the impact of the Doppler effects caused by the motion of the spacecraft on the X-ray pulsar-based navigation, an innovative navigation method using the pulse phase and Doppler frequency measurements of the X-ray pulsars is proposed. Given the initial estimate of the spacecraft's state,the real-time photon arrival model is established at the spacecraft with respect to the spacecraft's position and velocity predicted by the orbit dynamic model and their estimation errors. On this basis, a maximum likelihood estimation algorithm directly using the observed photon event timestamps is developed to extract a single pair of pulse phase and Doppler frequency measurements caused by the spacecraft's state estimation error. Since the phase estimation error increases as the observation time increases, we propose a new measurement updating scheme of referring the measurements to the middle time of an observation interval. By using the ground-based simulation system of X-ray pulsar signals, a series of photon-level simulations are performed. The results testify to the feasibility and real-timeliness of the proposed navigation method, and show that the incorporation of the Doppler measurement as well as the pulse phase into the navigation filter can improve the navigation accuracy. | XUE MengFan LI XiaoPing FU LingZhong FANG HaiYan SUN HaiFeng SHEN LiRong | 2015 | Science China Chemistry2015,58,12: | 5 |
| 12 | Domesticated cynomolgus monkey embryonic stem cells allow the generation of neonatal interspecies chimeric pigs显示文摘Blastocyst complementation by pluripotent stem cell(PSC)injection is believed to be the most promising method to generate xenogeneic organs.However,ethical issues prevent the study of human chimeras in the late embryonic stage of development.Primate embryonic stem cells(ESCs),which have similar pluripotency to human ESCs,are a good model for studying interspecies chimerism and organ generation.However,whether primate ESCs can be used in xenogenous grafts remains unclear.In this study,we evaluated the chimeric ability of cynomolgus monkey(Macaca fascicularis)ESCs(cmESCs)in pigs,which are excellent hosts because of their many similarities to humans.We report an optimized culture medium that enhanced the anti-apoptotic ability of cmESCs and improved the development of chimeric embryos,in which domesticated cmESCs(D-ESCs)injected into pig blastocysts differentiated into cells of all three germ layers.In addition,we obtained two neonatal interspecies chimeras,in which we observed tissue-specific D-ESC differentiation.Taken together,the results demonstrate the capability of D-ESCs to integrate and differentiate into functional cells in a porcine model,with a chimeric ratio of 0.001-0.0001 in different neonate tissues.We believe this work will facilitate future developments in xenogeneic organogenesis,bringing us one step closer to producing tissue-specific functional cells and organs in a large animal model through interspecies blastocyst complementation. | Rui Fu Dawei Yu Jilong Ren Chongyang Li Jing Wang Guihai Feng Xuepeng Wang Haifeng Wan Tianda Li Libin Wang Ying Zhang Tang Hai Wei Li Qi Zhou | 2020 | Protein & Cell2020,11,2: | 4 |
| 13 | Experimental Study on the Dynamic Mechanical Properties of Reinforced Concrete under Shock Loading显示文摘A simple experimental method was introduced to study the mechanical properties of reinforced concrete under shock loading. The one-stage light gas gun was used to test the mechanical properties of reinforced concrete with different reinforcement ratios under various impact velocities. Three Mn-Cu piezoresistive pressure gauges embedded in the target were used to record the voltage-time signals, from which the stress-strain curves of reinforced concrete were obtained using Lagrangian analysis. Experimental results indicated that the load-bearing capacities of reinforced concrete increased greatly with the impact velocity and the reinforcement ratio. The peak stress of the shock wave decreased exponentially with the propagation distance. | Haifeng Liu Jie Fu Jianguo Ning | 2016 | Acta Mechanica Solida Sinica2016,29,1: | 4 |

| 15 | In vitro and in vivo studies on the biodegradable behavior and bone response of Mg69Zn27Ca4 metal glass for treatment of bone defect显示文摘In the present work, the biodegradable behavior, cytocompatibility and osteogenesis activity of a Mg69Zn27Ca4 metal glass were investigated. Electrochemical test, immersion test, cytotoxicity test and histopathological evaluation were carried out. The results showed that there was a dense protective layer formed on the surface of Mg69Zn27Ca4 metal glass which could inhibit the degradation process in the Hank’s solution. In vitro cytotoxicity test showed that Mg69Zn27Ca4 metal glass had good biocompatibility. Histopathological evaluation showed that the degradation of Mg69Zn27Ca4 metal glass could promote the new bone formation with no obvious inflammatory reactions. After 2 months implantation, the diameter of the bone defect was reduced from the original φ6 mm to φ3.35 ± 0.40 mm with the degradation of Mg69Zn27Ca4 metal glass. Therefore, it can be concluded that Mg69Zn27Ca4 glass has great potential to be used as bone substitutes. | Junxiu Chen Jiahui Dong Huameng Fu Haifeng Zhang Lili Tan Dewei Zhao Ke Yang | 2019 | Journal of Materials Science & Technology2019,35,10: | 4 |
| 16 | Fe-based metallic glass:An efficient and energy-saving electrode material for electrocatalytic degradation of water contaminants显示文摘Excessive consumption of electrical energy has hampered the widespread application of electrochemical technology for degradation of various contaminants. In this paper, a Fe-based metallic glass(MG) was demonstrated as a new type of electrocatalyst to effectively and economically degrade an azo dye. In comparison to other typical electrodes, Fe-based MG electrodes exhibit a minimized degradation time, and the specific energy is 4-6 orders of magnitude lower than that of dimensionally stable anode(DSA), metal-like boron-doped diamond(BDD) and other electrodes. As sacrificial electrode materials, Fe-based MGs have less specific electrode mass consumption than iron electrodes. The use of Fe-based MGs will promote the practical application of electrochemical technology and the use of MGs as functional materials. | Xindong Qin Zhengkun Li Zhengwang Zhu Huameng Fu Hong Li Aimin Wang Hongwei Zhang Haifeng Zhang | 2018 | Journal of Materials Science & Technology2018,34,12: | 3 |

| 19 | Correlation Between Dynamic Compressive Strength and Fracture Behaviors of Bulk Metallic Glasses显示文摘The mechanical behaviors of Zr43.5Cu43.5Ni4Al8Nb1,Zr55.4Cu31.6Ni4Al8Nb1,Ti32.8Zr30.2Ni5.3Cu9Be22.7(at.%)metallic glass at different strain rates were studied.For all the present alloys,the dispersion over 700 MPa was observed on the strength in the repeated dynamic compressions,which was much stronger than that of the quasi-static compressive strength.Such the dispersion of the dynamic compressive strength was well correlated with the corresponding fracture behaviors.The area of fracture surface was calculated and also showed a strong dispersion for all the fractured specimens tested at the strain rate of 500 s^-1 and 1000 s^-1.All the specimens showed a linear relationship between the square of dynamic compressive strength and the area of fracture surface in the dynamic compression tests.This phenomenon was mainly thought to be related to the difference of mean initial free volume concentration of different samples,stress concentration caused by the split Hopkinson pressure bar experimental setup and high sensitivity of defects under dynamic deformation.These findings were beneficial to deeply understand the effect of strain rate on the mechanical properties of the metallic glass. | Wenqing Li Zhengwang Zhu Guojie Li Long Zhang Zhengkun Li Huameng Fu Hongwei Zhang Hong Li Aimin Wang Haifeng Zhang | 2020 | Acta Metallurgica Sinica(English Letters)2020,33,10: | 2 |
| 20 | Co_(78)Si_(8)B_(14)metallic glass:A highly efficient and ultra-sustainable Fenton-like catalyst in degrading wastewater under universal pH conditions显示文摘Overcoming the pH limitation and increasing the catalyst reusability remain pressing demands for metal-lic glass(MG)in wastewater remediation.Herein,Co_(78)Si_(8)B_(14)MG ribbons are used to degrade dye wastew-ater by activating hydrogen peroxide(H_(2)O_(2))as Fenton-like catalysts.The Co-based MG catalysts exhibit high degradation efficiency under both acidic and alkaline conditions,and the kinetic reaction rate at pH 10(0.176 min^(−1)) and pH 4(0.089 min^(−1)) is 5.9 and 1.2 times higher than that of the extensively studied Fe-based MG catalysts,respectively.Impressively,the Co-based MG catalysts can be reused up to 20-60 times at universal pH conditions,demonstrating fairly good reusability.The newly discovered Co-based MG catalysts do not follow the classical Fenton reactions with H_(2)O^(2) the way Fe-based MGs do.In an acid environment,hydroxyl radicals play a dominant role in the degradation,while in an alkaline environ-ment,the effect of hydroxyl radicals is weakened,and Co^(3+) ions exert a relatively major function on the degradation.The excellent performance in catalytic activity and reusability at universal pH conditions of the Co-based MGs will inspire the development of MGs in wastewater treatment. | Xindong Qin Jiliang Xu Zhengwang Zhu Zhengkun Li Dawei Fang Huameng Fu Shiming Zhang Haifeng Zhang | 2022 | Journal of Materials Science & Technology2022,,18: | 2 |
