| 1 | Effect of dissolved organic matter on adsorption and desorption of mercury by soils显示文摘Effects of dissolved organic matter (DOM) on adsorption and desorption of Hg were investigated in two kinds of soils, Xanthi-Udic Ferralosols (XUF) and Typic Purpli-Udic Cambosols (TPUC). The DOM was obtained from humus soil (DOMH), rice straw (DOMR), and pig manure (DOMP). The presence of DOM obviously reduced Hg maximum adsorption capacity with up to 40% decreases over the control, being an order of DOMH (250.00 mg/kg)< DOMR (303.03 mg/kg) < DOMP (322.58 mg/kg) < CK (control 416.67 mg/kg) for the XUF and DOMH (270.27 mg/kg) < DOMR (312.50 mg/kg) < DOMP (324.23 mg/kg) < CK (476.11 mg/kg) for the TPUC, respectively. The inhibition of DOM on Hg adsorption was slightly weaker in XUF than in TPUC. Meanwhile, the DOM promoted Hg desorption from the soils. The kinetic models, the Two-constant equation and Elovich equation, were applicable to describe the adsorption and desorption processes of Hg in soils. The speed of Hg adsorption was consistently slowed down by the existence of DOM. | YANG, Yongkui LIANG, Li WANG, Dingyong | 2008 | Journal of Environmental Sciences2008，20，9： | 23 |
| 2 | MicroRNA-548 down-regulates host antiviral response via direct targeting of IFN-λ1显示文摘Interferon(IFN)-mediated pathways are a crucial part of the cellular response against viral infection.Type III IFNs,which include IFN-λ1,2 and 3,mediate antiviral responses similar to Type I IFNs via a distinct receptor complex.IFN-λ1 is more effective than the other two members.Transcription of IFN-λ1 requires activation of IRF3/7 and nuclear factor-kappa B(NF-κB),similar to the transcriptional mechanism of Type I IFNs.Using reporter assays,we discovered that viral infection in-duced both IFN-λ1 promoter activity and that of the 3′-untranslated region(UTR),indicating that IFN-λ1 expression is also regulated at the post-transcriptional level.After analysis with microRNA(miRNA)prediction programs and 3′UTR targeting site assays,the miR-NA-548 family,including miR-548b-5p,miR-548c-5p,miR-548i,miR-548j,and miR-548n,was identified to target the 3′UTR of IFN-λ1.Further study demonstrated that miRNA-548 mimics down-regulated the expression of IFN-λ1.In contrast,their inhibitors,the complemen-tary RNAs,enhanced the expression of IFN-λ1 and IFN-stimulated genes.Furthermore,miRNA-548 mimics promoted infection by enterovirus-71(EV71)and ve-sicular stomatitis virus(VSV),whereas their inhibitors significantly suppressed the replication of EV71 and VSV.Endogenous miRNA-548 levels were suppressed during viral infection.In conclusion,our results sug-gest that miRNA-548 regulates host antiviral response via direct targeting of IFN-λ1,which may offer a poten-tial candidate for antiviral therapy. | Yongkui Li Jiajia Xie Xiupeng Xu Jun Wang Fang Ao Yushun Wan Ying Zhu | 2013 | Protein & Cell2013，4，2： | 22 |

| 4 | Hepatitis B virus X protein suppresses virus-triggered IRF3 activation and IFN-β induction by disrupting the VISA-associated complex显示文摘Viral RNAs produced during viral infection are recognized by the cytoplasmic RNA helicases retinoic acid-inducible gene-I(RIG-I)and melanoma differentiation-associated gene 5(MDA5).A central adapter protein downstream of RIG-I and MDA5 is the mitochondrial membrane protein virus-induced signaling adaptor(VISA),which mediates the induction of type I interferons(IFNs)through the activation of transcription factors such as nuclear factor-kappaB(NF-kB)and IFN-regulatory factor-3(IRF3).Here we found that hepatitis B virus(HBV)-encoded X protein(HBx)acts as an inhibitor of virus-triggered IRF3 activation and IFN-b induction.Reporter and plaque assays indicate that HBx inhibits signaling by components upstream but not downstream of VISA.Immunoprecipitation experiments indicate that HBx interacts with VISA and disrupts the association of VISA with its upstream and downstream components.These findings suggest that HBx acts as a suppressor of virus-triggered induction of type I IFNs,which explains the observation that HBV causes transient and chronic infection in hepatocytes but fails to activate the pattern recognition receptor-mediated IFN induction pathways. | Xianmiao Wang Ying Li Aiping Mao Chao Li Yongkui Li Po Tien | 2010 | Cellular & Molecular Immunology2010，7，5： | 13 |
| 5 | Downwash distribution of single-rotor unmanned agricultural helicopter on hovering state显示文摘The effective coverage and velocity of downwash are directly related to the assemblage of spraying system and spraying effect.The downwash of the unmanned agricultural helicopter(UAH)N-3 was discussed in the paper.The computational fluid dynamics(CFD)methods were used to simulate and analyze the distribution of the downwash,and a wind field measurement device had been designed to test the downwash of UAH N-3.In the tests,the UAH N-3 was raised up to 5.0 m,6.0 m and 7.0 m from the ground,“annular-radial-distribution-point”method was introduced,8 directions separated by an angle of 45°(the radial direction)with the intersection point of the main rotor shaft and the ground plane as the center,0.5 m as the step length for the longitudinal(to 2.5 m)and radial(to 4.0 m)direction to set the sample points,considering the range of the rotor rotating circular area mainly.The 5 m height results of N-3 were fully discussed to describe the downwash distribution with the longitudinal altitude increased and the radial distance increased.The standard deviations of five test altitudes for eight directions were comparatively analyzed,the results showed that the total standard deviation was not greater than 0.6 m/s.The overall relative maximum margin of error calculated from the simulation and measurement data was between 0.6 and 0.7,which verified the credibility of the simulation data.High-order polynomials were used to fitting the simulation and measurement data,the fitting results showed that the polynomial coefficient of determination R^(2) met or exceeded 0.75 when the altitudes were more than 1 m,indicating the fit equation having the reference values.When the altitudes equal or less than 0.5 m,the polynomial coefficient of determination R^(2) was smaller,ranging during 0.3 to 0.7.The study would provide some foundations for the optimization of the assemblage of spraying system on the single-rotor UAH,which would promote China aviation plant protection. | Zhang Songchao Xue Xinyu Sun Zhu Zhou Lixin Jin Yongkui | 2017 | International Journal of Agricultural and Biological Engineering2017，10，5： | 13 |
| 6 | Grasping institutional complexity in infrastructure megaprojects through the multi-level governance system: A case study of the Hong Kong-Zhuhai-Macao Bridge construction显示文摘This study analyzes the design and operation of multi-level governance system for the smooth delivery of infrastructure mega-projects with high institutional complexity caused by market transition. From an institutional perspective, this study scrutinizes the structure,elements, and dynamics of the governance system of infrastructure mega-projects and then proposes an integrative framework based on the inductive case study of the Hong Kong-Zhuhai-Macao Bridge mega-project. Multiple evidences of archives, field studies, and interviews related to the case project are triangulated to further analyze the institutional effects, specifically those with government logics and market structures, on the design and operation of the three-level governance system. Results reveal that the co-evolution between governments and markets in China has shaped the vertical levels of the mega-project governance system and has further affected their evolution and operation across various stages of project development. This study contributes to the rapidly emerging research on complex system governance by proposing a systematic model of three-level mega-project governance to enhance the timely delivery of infrastructure megaprojects within budget. | Yi HU Yun LE Xinglin GAO Yongkui LI Mingqiang LIU | 2018 | Frontiers of Engineering Management2018，5，1： | 9 |
| 7 | Low-temperature activation of methane over rare earth metals promoted Zn/HZSM-5 zeolite catalysts in the presence of ethylene显示文摘At low temperature of 723 K, methane can be easily activated in the presence of ethylene in the feed, and converted to higher hydrocarbons (C2–C4) and aromatics (C6–C10), through its reaction over rare metals modified Zn/HZSM-5 zeolite catalysts without undesirable carbon oxides formation. Methane can get 37.3% conversion over the above catalysts under low temperature, and the catalysts show a longer lifetime than usual metal supported HZSM-5 zeolite catalysts without adding any rare earth metals. The effects of methane activation over various rare earth metal promoted Zn/HZSM-5 catalysts on the products and influences of several reaction conditions such as temperature, catalyst lifetime and molar ratio of CH4/C2H4 have been discussed. | Hengqiang Zhang Aiguo Kong Yongjie Ding Chengyong Dai Yongkui Shan | 2011 | Journal of Natural Gas Chemistry2011，20，3： | 4 |

| 9 | Condition Monitoring for Railway Point Machines Based on Sound Analysis and Support Vector Machine显示文摘Railway point machines(RPMS)are one of the key equipments in the railway system to switch different routes for the trains.Condition monitoring for RPMs is a vital measure to keep train operation safe and reliable.Taking convenience and low cost into consideration,a novel intelligent condition monitoring method for RPMs based on sound analysis is proposed.Time-domain and frequency-domain features are obtained,and normalized using z-score standardization method to eliminate the influences of different dimensions.Binary particle swarm optimization(BPSO)is utilized to select the most significant discrimination feature subset.The effects of the selected optimal features are verified using Support vector machine(SVM),1-Nearest neighbor(1 NN),Random forest(RF),and Naive Bayes(NB).Experiment results indicate SVM performs best on identification accuracy and computing cost compared with the other three classifiers.The identification accuracies on normal switching and reverse switching processes reach 100% and 99.67%,respectively,indicating the feasibility of the proposed method. | SUN Yongkui CAO Yuan XIE Guo WEN Tao | 2020 | Chinese Journal of Electronics2020，29，4： | 3 |
| 10 | (N,F)-codoped TiO_2 Nanocrystals as Visible Light-activated Photocatalyst显示文摘(N, F)-codoped anatase TiO2 nanocrystals with active visible light response were prepared by using a simple sol-gel approach. X-ray photoelectron spectroscopy measurements suggested that the substitutional N and F species replaced the lattice oxygen atoms in TiO2 nanocrystals. Such nanocrystals showed strong absorption from 400 to 550 nm, which was mainly induced by nitrogen doping. The phase transformation from anatase to rutile was hindered by fluorine doping at high calcination temperatures, which was verified by XRD patterns. The N2 adsorption-desorption isotherms revealed the absence of mesopores in these nanocrystals. The (N, F)-codoped TiO2 nanocrystals showed satisfying photocatalytic activity on the photo-degradation of methylene blue under visible light. | Yanling Meng Jiansong Chen Ying Wang Hanming Ding Yongkui Shan | 2009 | Journal of Materials Science & Technology2009，25，1： | 3 |
| 11 | A simulation study of mercury release fluxes from soils in wet–dry rotation environment显示文摘A simulative mesocosm study was conducted to evaluate the influence of wet–dry rotation on mercury(Hg) flux from soil/water to air and the distribution of Hg species in water as well as Hg chemical fractions in soil. Three types of soil were employed including two kinds of paddy soil, Typic Purpli-Udic Cambosols(TPUC) and Xanthi-Udic Ferralosols(XUF), as well as the Alluvial Soil(AS) from Three Gorge reservoir area in Chongqing, China. The results showed that Hg fluxes in wetting periods were significantly higher than that in drying periods. It might be due to the formation of a layer of stable air over the water surface in which some redox reactions promote evasion processes over the water surface. This result indicated that more Hg would be evaporated from the Three Gorge reservoir and paddy soil field during the flooding season. Hg fluxes were positively correlated with air temperature and solar irradiation, while negatively correlated with air humidity and the electronic conductivity of water. Hg fluxes from AS and TPUC were significantly higher than that from XUF, which might be due to the higher organic matter(OM) contents in XUF than TPUC and AS. The reduction processes of oxidized Hg were restrained due to the strong binding of Hg to OM, resulting in the decrease in Hg flux from the soil. | Peng Liang Cheng Zhang Yongkui Yang Dingyong Wang | 2014 | Journal of Environmental Sciences2014，26，7： | 3 |
| 12 | Effect of dissolved organic matter on mercury release from water body显示文摘Dissolved organic matter(DOM) plays an important role in the process of mercury release from water body.In this study,the influence of DOM from different sources(DOMR,DOMS and DOMH,extracted from rice straw,compost and humic soil respectively) on mercury reduction was investigated.The molecular weight distribution and chemical composition of DOM from each source were determined using ultrafiltration membrane technique and elemental analysis respectively.The result showed that mercury release from DOM-added samples was much lower than the control;the lowest mercury release flux was observed in the treatment of DOMH,25.02% of the control,followed by DOMS and DOMR,62.46% and 64.95% of the control,respectively.The higher saturation degree and lower molecular weight of DOMH was responsible for the highest inhibition degree on the mercury release.The link between DOMH,concentration and mercury flux was also estimated and the result showed that mercury flux was increased with DOMH at lower concentration,while decreased with DOMH at higher concentration.Different mechanism dominated the influence of DOM on mercury release with variation of DOM concentration. | Yutao Zhang Xi Chen Yongkui Yang Dingyong Wang Xiao Liu | 2011 | Journal of Environmental Sciences2011，23，6： | 3 |
| 13 | Unadulterated carbon as robust multifunctional electrocatalyst for overall water splitting and oxygen transformation显示文摘Developing the highly efficient and durable non-precious metal electrocatalysts by taking advantage of inexpensive and abundant resources is of paramount importance for the widespread application of energy conversion and storage techniques such as fuel cells and metal-air batteries.Herein,the sponge-like unadulterated carbontube-graphene complexes(D/G-CTs-1,000)with multifarious intrinsic defect active sites are fabricated by boric acid-hydrothermal and pyrolysis treatments.The close contact or juncture between open nanotubes and few-layer graphene in D/G-CTs-1,000 constructs the hierarchical networks with plentifuchannels,the larger surface area and outstanding conductivity.As a result,the as-prepared D/G-CTs-1,000 electrocatalyst exhibits an excellent trifunctional electrocatalytic performance for oxygen reduction reaction(ORR),oxygen evolution reactior(OER)and hydrogen evolution reaction(HER).The primary Zn-air batteries and overall water splitting system using D/G-CTs-1,000 as the electrode materials delivers higher power density outperforming the advanced Pt/C-based batteries and the overall watersplitting performance comparable to those using the non-precious metal/carbon-based materials as electrode.This work provides a universal and efficient synthetic strategy to produce the unadulterated carbons with high activity and long-time durability as trifunctional electrocatalysts and promote the widespread applications of metal-free electrocatalysts in sustainable energy conversior technology. | Fantao Kong Yu Qiao Chaoqi Zhang Xiaohong Fan Aiguo Kong Yongkui Shan | 2020 | Nano Research2020，13，2： | 3 |

| 20 | Direct growth of special-shape graphene on different templates by remote catalyzation of Cu nanoparticles显示文摘A novel method avoiding the complex transfer process is proposed to directly grow low-defect and few-layer graphene on different insulating substrates(SiO_2, Al_2O_3, etc.) by remote catalyzation of Cu nanoparticles(NPs) using ambient pressure chemical vapor deposition(APCVD). The insulating substrates with special structure are used as templates to grow wrapped graphene sheets with special shapes.Hollow graphene species are obtained by removing the substrates. The prime feature of the proposed method is using Cu NPs as catalyst rather than metal foils. The Cu NPs play an important role in the remote catalyzation during the nucleation of graphene. This method can improve the quality and relatively decrease the growth temperature of the graphene on the insulating substrates, which displays the great potential of APCVD direct growth of graphene on dielectric substrates for electronic and photovoltaic applications. | Shuangshuang Han Fan Yang Liyue Liu Mi Zhou Yongkui Shan Dezeng Li | 2017 | Journal of Materials Science & Technology2017，33，8： | 1 |
