| 1 | Enhanced removal of ethylbenzene from gas streams in biotrickling filters by Tween-20 and Zn(Ⅱ)显示文摘The effects of Tween-20 and Zn(II)on ethylbenzene removal were evaluated using two biotrickling filters(BTFs),BTF1 and BTF2.Only BTF1 was fed with Tween-20 and Zn(II).Results show that ethylbenzene removal decreased from 94%to 69%for BTF1 and from 74%to 54%for BTF2 with increased organic loading from 64.8 to 189.0 g ethylbenzene/(m3·hr)at EBRT of 40 sec.The effect of EBRT(60–15 sec)at a constant ethylbenzene inlet concentration was more significant than that of EBRT(30–10 sec)at a constant organic loading.Biomass accumulation rate within packing media was reduced significantly. | Lu Wang Chunping Yang Yan Cheng Jian Huang Haining Yang Guangming Zeng Li Lu Shanying He | 2014 | Journal of Environmental Sciences2014，26，12： | 8 |
| 2 | Microstructure and Mechanical Properties of Aer Met 100 Ultra-high Strength Steel Joints by Laser Welding显示文摘Aer Met100 ultra-high strength steel plates with a thickness of 2 mm were welded using a CO2 laser welding system. The influences of the welding process parameters on the morphology and microstructure of the welding joints were investigated, and the mechanical property of the welding joints was analyzed. The experimental results showed that the fusion zone of welding joint mainly consisted of columnar grains and a fine dendrite substructure grew epitaxially from the matrix. With the other conditions remaining unchanged, a finer weld microstructure was along with the scanning speed increase. The solidification microstructure gradually transformed from cellular crystal into dendrite crystal and the spaces of dendrite secondary arms rose from the fusion line to the center of the fusion zone. In the fusion zone of the weld, the rapid cooling caused the formation of martensite, which led the microhardness of the fusion zone higher than that of the matrix and the heat affected zone. The tensile strength of the welding joints was tested as 1 700 MPa, which was about 87% of the matrix. However, the tensile strength of the welding joints without defects existed was tested as 1832 MPa, which was about 94% of the matrix. | 刘奋成 YU Xiaobin HUANG Chunping HE Lihua CHEN Yuhua BU Wende | 2015 | Journal of Wuhan University of Technology(Materials Science)2015，30，4： | 4 |

| 4 | Generation and Analysis of Pathogenicity-related Gene Mutants of Colletotrichum gloeosporioides Using a Novel Promoter Trapping System显示文摘Agrobacterium tumefaciens-mediated transformation(ATMT) is an efficient tool for insertional mutagenesis and is used in a wide variety of plants. This paper reports a promoter trapping method to generate mutants in the filamentous fungus,Colletotrichum gloeosporioides,by ATMT insertion of a trapping vector(pCAHPH) that carries a promoterless hygromycin phosphotransferase(hph) gene. Transformants were selected on the media containing 200 μg/mL hygromycin B,and screened for pathogenicity-related gene mutants. Their pathogenicity-related mutants T-DNA flanking sequences were then cloned and analyzed. Hph genes were amplified from mutant genomic DNA but not from wild-type DNA,indicating that the phenotypic alternations of these mutants were the results of T-DNA insertion. T-DNA flanking sequences were obtained using modified thermal asymmetric interlaced PCR. Two right-sided flanking sequences were highly homologous to proteins from other species. | Zheng Xiaolan Liu Yan Wei Xiaohui He Chunping Wu Weihuai Liang Yanqiong Li Rui Zheng Fucong | 2013 | Plant Diseases and Pests2013，4，3： | 3 |
| 5 | Biodegradation of 3,5-dimethyl-2,4-dichlorophenol in saline wastewater by newly isolated Penicillium sp.yz11-22N2显示文摘In this study,the performance of 3,5-dimethyl-2,4-dichlorophenol(DCMX) degradation by a screened strain was investigated.18 S r DNA and the neighbor-joining method were used for identification of the isolated strain.The results of phylogenetic analysis and scanning electron micrographs showed that the most probable identity of the screened strain should be Penicillium sp.Growth characteristics of Penicillium sp.and degradation processes of DCMX were examined.Fourier transform infrared spectroscopy of the inoculated DCMX solution was recorded,which supported the capacity of DCMX degradation by the screened Penicillium sp.Under different salinity conditions,the highest growth rate and removal efficiency for DCMX were obtained at p H 6.0.The removal efficiency decreased from 100%to 66% when the DCMX concentration increased from 5 to 60 mg/L,respectively.Using a Box–Behnken design,the maximum DCMX removal efficiency was determined to be 98.4%.With acclimation to salinity,higher removal efficiency could be achieved.The results demonstrate that the screened Penicillium sp.has the capability for degradation of DCMX. | Zhou Yan Huijun He Chunping Yang Guangming Zeng Le Luo Panpan Jiao Huiru Li Li Lu | 2017 | Journal of Environmental Sciences2017，29，7： | 3 |
| 6 | Influences of anion concentration and valence on dispersion and aggregation of titanium dioxide nanoparticles in aqueous solutions显示文摘Dispersion and aggregation of nanoparticles in aqueous solutions are important factors for safe application of nanoparticles. In this study, dispersion and aggregation of nano-TiO_2 in aqueous solutions containing various anions were investigated. The influences of anion concentration and valence on the aggregation size, zeta potential and aggregation kinetics were individually investigated. Results showed that the zeta potential decreased from 19.8 to-41.4 mV when PO_4^(3-) concentration was increased from 0 to 50 mg/L, while the corresponding average size of nano-TiO_2 particles decreased from 613.2 to 540.3 nm. Both SO_4^(2-) and NO_3^-enhanced aggregation of nano-TiO_2in solution. As SO_4^(2-) concentration was increased from 0 to 500 mg/L, the zeta potential decreased from 19.8 to 1.4 mV, and aggregate sizes increased from 613.2 to 961.3 nm.The trend for NO_3^- fluctuation was similar to that for SO_4^(2-) although the range of variation for NO_3^- was relatively narrow. SO_4^(2-) and NO_3^-accelerated the aggregation rapidly, while PO_4^(3-) did so slowly. These findings facilitate the understanding of aggregation and dispersion mechanisms of nano-TiO_2 in aqueous solutions in the presence of anions of interest. | Huijun He | 2017 | Journal of Environmental Sciences2017，29，4： | 2 |
| 7 | Strongly convex weakly complex Berwald metrics and real Landsberg metrics显示文摘Under the assumption that' is a strongly convex weakly Khler Finsler metric on a complex manifold M, we prove that F is a weakly complex Berwald metric if and only if F is a real Landsberg metric.This result together with Zhong(2011) implies that among the strongly convex weakly Kahler Finsler metrics there does not exist unicorn metric in the sense of Bao(2007). We also give an explicit example of strongly convex Kahler Finsler metric which is simultaneously a complex Berwald metric, a complex Landsberg metric,a real Berwald metric, and a real Landsberg metric. | Yong He Chunping Zhong | 2018 | Science China Mathematics2018，61，3： | 2 |

| 9 | Efficient removal of naphthalene-2-ol from aqueous solutions by solvent extraction显示文摘Naphthalene-2-ol is a typical biologically recalcitrant pollutant in dye wastewater.Solvent extraction of naphthalene-2-ol from aqueous solutions using mixed solvents was investigated.Various extractants and diluents were evaluated,and the effects of volume ratio of extractant to diluent,initial p H,initial concentration of naphthalene-2-ol in aqueous solution,extraction time,temperature,volume ratio of organic phase to aqueous phase(O/A),stirring rate and extraction stages,on extraction efficiency were examined separately.Regeneration and reuse of the spent extractant were also investigated.Results showed that tributyl phosphate(TBP) achieved 98% extraction efficiency for naphthalene-2-ol in a single stage extraction,the highest among the 12 extractants evaluated.Extraction efficiency was optimized when cyclohexane and n-octane were used as diluents.The solvent combination of 20% TBP,20% n-octanol and 60% cyclohexane(V/V) obtained the maximum extraction efficiency for naphthalene-2-ol,99.3%,within 20 min using three cross-current extraction stages under the following extraction conditions:O/A ratio of 1:1,initial p H of 3,25°C and stirring rate of 150 r/min.Recovery of mixed solvents was achieved by using 15%(W/W) Na OH solution at an O:A ratio of 1:1 and a contact time of 15 min.The mixed solvents achieved an extraction capacity for naphthalene-2-ol stably higher than90% during five cycles after regeneration. | Jingjing Shao | 2016 | Journal of Environmental Sciences2016，28，9： | 1 |

| 12 | 乳腺癌干细胞多药耐药基因的表达及意义(英文)显示文摘Objective: To approach the expressions of MDR1 and BCRP in breast cancer stem cells and differentiated cells. Methods: The breast cancer stem cells were separated from human breast cancer primary tissues and MCF-7 by flow cytometry. Then we measured the expressions of MDR1 and BCRP with different subset cells by Realtime-PCR. Results: Contrasted with breast cancer differentiated cells, the expressions of MDR1 and BCRP in breast cancer stem cells were higher (P < 0.01), and the proportion of stem cells rose after chemotherapy (P < 0.01). Conclusion: Contrasted with breast cancer differentiated cells, breast cancer stem cells have stronger ability of drug-resistance with higher level of multi-drug resistance genes, and it is one of key points for chemotherapy failure of breast cancer. | Zhi Li Chunping Liu Yanli He Jinghui Zhang Tao Huang | 2008 | The Chinese-German Journal of Clinical Oncology2008，7，9： | 0 |
| 13 | Two-dimensional 1T-PS2 as a promising anode material for sodium-ion batteries with ultra-high capacity, low average voltage and appropriate mobility显示文摘As electrodes,two-dimensio nal materials show special advantages including the infinite planar lengths,broad electrochemical window,large surface-volume ratio,and much exposed active sites.In theory,the two-dimensional materials consist of the elements with high electronegativity may absorb more Na atoms,resulting in a high battery storage capacity.Based on the above idea,we selected the two dimensional metallic PS2 with 1 T-Type structure as an anode material,and explored its potential applications as an electrode material for Na-ion battery through first-principle calculations.As we expected,when two dimensional PS2 is used as an anode in Na-ion battery,it can adsorb maximum three layers of sodium atoms on both sides of the monolayer,resulting in a maximum theoretical capacity of 1692 mAh/g.Furthermore,it also possesses a rather small sodium diffusion barrier of 0.17 eV,a low average open-circuit voltage of 0.18 V,and a relatively small lattice changes within 13% during the intercalation of Na.These results suggested that the two dimensional PS2 is a potentially excellent Na-ion battery anode.Our idea of designing two-dimensional anode materials with high storage capacity may provide some references for designing the next generation anode materials of metal-ion batteries. | Dawei Zhou Chunping Li Furong Yin Xin Tang Chunying Pu Chaozheng He | 2020 | Chinese Chemical Letters2020，31，9： | 0 |
| 14 | Numerical Simulation Study on Wear of Spur Gears under Dynamic Conditions显示文摘A numerical simulation model is proposed to predict the wear depth of gears,where Archard's wear equation and a nonlinear dynamic model are combined to establish a wear calculation model under dynamic conditions.The dynamic meshing force,determined by the non-linear dynamic model,and the sliding coefficient are used by Archard's wear equation to calculate the surface wear.Then the dynamic meshing force and sliding coefficient would be recalculated according to the surface wear state.After repeated iterations,the simulation results show that the peak and fluctuation of the meshing force increase first,then decrease,and eventually maintain stability during the process of wear.As for the distribution of wear depth,its fluctuation also increases first and then declines.Finally,the distribution of wear depth becomes V-shaped.Comparing the trends of the two factors,it is clear that the meshing force and wear depth are closely related.Moreover,the wear rate maintains a higher constant value first and then declines to a lower constant value. | Changsong Zheng Zhouli Zhang Chunping He Weipeng Lou Huizhu Li Qiu Du | 2019 | Journal of Beijing Institute of Technology2019，28，1： | 0 |
| 15 | Voxel modeling and association of ubiquitous spatiotemporal information in natural language texts显示文摘The ubiquitous spatiotemporal information extracted from Internet texts limits its application in spatiotemporal association and analysis due to its unstructured nature and uncertainty.This study uses ST-Voxel modeling to solve the problem of structured modeling and the association of ubiquitous spatiotemporal information in natural language texts.It provides a new solution for associating ubiquitous spatiotemporal information on the Internet and discovering public opinion.The main contributions of this paper include:(1)It proposes a convolved method for ST-Voxel,which solves the voxel modeling problem of unstructured and uncertain spatiotemporal objects and spatiotemporal relation in natural language texts.Experiments show that this method can effectively model 5 types of spatiotemporal objects and 16 types of uncertain spatiotemporal relation founded in texts;(2)It realizes the unknown event discovery based on voxelized spatiotemporal information association.Experiments show that this method can effectively solve the aggregation of ubiquitous spatiotemporal information in multi-natural language texts,which is conducive to discovering spatiotemporal events.The selection of convolution parameters in voxel modeling is also discussed.A parameter selection method for balancing the discovery capability and discovery accuracy of spatiotemporal events is given. | Dali Wang Xiaochong Tong Chenguang Dai Congzhou Guo Yi Lei Chunping Qiu He Li Yuekun Sun | 2023 | International Journal of Digital Earth2023，16，1： | 0 |
| 16 | Assessing outdoor air quality vertically in an urban street canyon and its response to microclimatic factors显示文摘The vertical distribution of air pollutants in urban street canyons is closely related to residents’health.However,the vertical air quality in urban street canyons has rarely been assessed using field observations obtained throughout the year.Therefore,this study investigated the seasonal and annual concentrations of particulate matter(PM2.5 and PM10),CO,NO_(2),SO_(2),O_(3),air quality index,and their responses to microclimatic factors at three height levels(1.5,27,and 69 m above street level)in an urban street canyon.The PM concentration was higher at 27 m than at 1.5 m in winter,whereas the situation was reversed in other seasons.It was found that photochemical pollutants such as NO_(2) and O_(3) were the primary pollutants in the urban street canyon.The days on which O3 was the primary pollutant at the height of 1.5 m accounted for 81.07% of the entire year.The days on which NO_(2) was the primary pollutant at the height of 27 and 69 m accounted for 82.49% and 72.33%of the entire year,respectively.Substantially higher concentrations of NO2 and O_(3) were found at the height of 27 m than at 69 m.In-canyon concentrations of NO_(2) and O_(3) were strongly correlated with air temperature,wind speed,and wind direction,which played important roles in photochemical reactions and pollutant dispersion. | Chunping Miao Shuai Yu Yue Zhang Yuanman Hu Xingyuan He Wei Chen | 2023 | Journal of Environmental Sciences2023，，2： | 0 |
