| 1 | Spatial Pattern Evolution and Casual Analysis of County Level Economy in Changsha-Zhuzhou-Xiangtan Urban Agglomeration, China显示文摘In order to evaluate whether or not the county units′ economy in the Changsha-Zhuzhou-Xiangtan(Chang-Zhu-Tan) Urban Agglomeration was growing as expected, this study analyzed the spatial economy pattern at county-level by using the Exploratory Spatial Data Analysis(ESDA) method. In this process, the global Moran′s I and local Getis-Ord G*i indexes were employed to analyze indicators including per capita GDP and three industrials(i.e. primary, secondary and tertiary industry) from 2000 to 2010. The results show that: 1) the county units′ economy in the Chang-Zhu-Tan Urban Agglomeration has exhibited a strong spatial autocorrelation and an accelerated integration trend since 2008(Moran′ s I increased from 0.26 to 0.56); 2) there is a significant difference in economy development between the northern and southern county units in the Chang-Zhu-Tan Urban Agglomeration: the hotspot zone with high economic level was formed among the northern county units whereas the coldspot zone with low economic level was located in the southern areas. This difference was caused primarily by the increasingly prominent economic radiation effect of Changsha ′upheaval′; 3) town density, secondary industry, and the integration policy are the major contributors driving the evolution of the spatial economy pattern in the Chang-Zhu-Tan Urban Agglomeration. | DONG Minghui ZOU Bin PU Qiang WAN Neng YANG Lingbin LUO Yanqing | 2014 | Chinese Geographical Science2014,24,5: | 8 |
| 2 | A flow cytometer based protocol for quantitative analysis of bloom-forming cyanobacteria(Microcystis) in lake sediments显示文摘A quantitative protocol for the rapid analysis of Microcystis cells and colonies in lake sediment was developed using a modified flow cytometer,the CytoSense.For cell enumeration,diluted sediment samples containing Microcystis were processed with sonication to disintegrate colonies into single cells.An optimized procedure suggested that 5 mg dw(dry weight)/mL dilution combined with 200 W × 2 min sonication yielded the highest counting efficiency.Under the optimized determination conditions,the quantification limit of this protocol was 3.3×10 4 cells/g dw.For colony analysis,Microcystis were isolated from the sediment by filtration.Colony lengths measured by flow cytometry were similar to those measured by microscopy for the size range of one single cell to almost 400 μm in length.Moreover,the relationship between colony size and cell number was determined for three Microcystis species,including Microcystis flos-aquae,M.aeruginosa and M.wessenbergii.Regression formulas were used to calculate the cell numbers in differentsized colonies.The developed protocol was applied to field sediment samples from Lake Taihu.The results indicated the potential and applicability of flow cytometry as a tool for the rapid analysis of benthic Microcystis.This study provided a new capability for the high frequency monitoring of benthic overwintering and population dynamics of this bloom-forming cyanobacterium. | Quan Zhou Wei Chen Huiyong Zhang Liang Peng Liming Liu Zhiguo Han Neng Wan Lin Li Lirong Song | 2012 | Journal of Environmental Sciences2012,24,9: | 5 |

| 10 | Efficient photocatalytic hydrogen evolution coupled with benzaldehyde production over 0D Cd_(0.5)Zn_(0.5)S/2D Ti_(3)C2 Schottky heterojunction显示文摘Converting water into hydrogen fuel and oxidizing benzyl alcohol to benzaldehyde simultaneously under visible light illumination is of great significance,but the fast recombination of photogenerated carriers in photocatalysts seriously decreases the conversion efficiency.Herein,a novel dual-functional 0D Cd_(0.5)Zn_(0.5)S/2D Ti_(3)C2 hybrid was fabricated by a solvothermally in-situ generated assembling method.The Cd_(0.5)Zn_(0.5)S nano-spheres with a fluffy surface completely and uniformly covered the ultrathin Ti_(3)C2 nanosheets,leading to the increased Schottky barrier(SB)sites due to a large contact area,which could accelerate the electron–hole separation and improve the light utilization.The optimized Cd_(0.5)Zn_(0.5)S/Ti_(3)C2 hybrid simultaneously presents a hydrogen evolution rate of 5.3 mmol/(g·h)and a benzaldehyde production rate of 29.3 mmol/(g·h),which are~3.2 and 2 times higher than those of pristine Cd_(0.5)Zn_(0.5)S,respectively.Both the multiple experimental measurements and the density functional theory(DFT)calculations further demonstrate the tight connection between Cd_(0.5)Zn_(0.5)S and Ti_(3)C2,formation of Schottky junction,and efficient photogenerated electron–hole separation.This paper suggests a dual-functional composite catalyst for photocatalytic hydrogen evolution and benzaldehyde production,and provides a new strategy for preventing the photogenerated electrons and holes from recombining by constructing a 0D/2D heterojunction with increased SB sites. | Junnan TAO Mingyuan WANG Guiwu LIU Qinqin LIU Lei LU Neng WAN Hua TANG Guanjun QIAO | 2022 | Journal of Advanced Ceramics2022,11,7: | 1 |

| 17 | Biological oyster shell waste enhances polyphenylene sulfide composites and endows them with antibacterial properties显示文摘To date,there is no research that deals with biological waste as fillers in polyphenylene sulfide(PPS).In this study,oyster shells were recycled and treated to prepare thermally-treated oyster shells(TOS),which were used as PPS fillers to make new bio-based antibacterial composite materials.The effect of varying the content of TOS was studied by means of structure and performance characterization.PPS/TOS composites were demonstrated to have an antibacterial effect on the growth of E coli and S.aureus.Qualitative analysis showed that when the TOS content was≥30%and 40%,the composite materials had an apparent inhibition zone.Quantitative analysis showed that the antibacterial activity increased with the TOS content.Fourier transform infrared spectroscopy indicated the formation of hydrogen bonds between the molecular chains of TOS and PPS and the occurrence of a coordination reaction.At 10%TOS,the composite tensile strength reached a maximum value of 72.5 MPa,which is 9.65%higher than that of pure PPS.The trend of bending properties is the same as that of tensile properties,showing that the maximum property was reached for the composite with 10%TOS.At the same time,the crystallinity and contact angle were the highest,and the permeability coefficient was the lowest.The fatigue test results indicated that for the composite with 10%TOS,the tensile strength was 23%lower than static tensile strength,and the yield strength was 10%lower than the static yield strength.The results of the study showed that TOS not only could reduce the cost of PPS,but also could impart antibacterial properties and enhance the mechanical and,barrier properties,the thermostability,as well as the crystallinity. | Chi-Hui Tsou Rui Zeng Neng Wan Manuel Reyes De Guzman Xue-Fei Hu Tao Yang Chen Gao Xiaomei Wei Jia Yi Li Lan Rui-Tao Yang Ya-Li Sun | 2023 | Chinese Journal of Chemical Engineering2023,57,5: | 0 |
| 18 | A new localization theory of adaptive machining of near-net-shape blades显示文摘In the fabrication of aero-engine blades,a great deal is gained when massive material removal is avoided at the end of the process,and as little as possible material is left on the blade billet.Due to the uncertainty of pre-process,the billet shapes are inconsistent.Sometimes,the near-net-shape billet doesn’t cover the blade design surface to be cut.Therefore,blade localization is necessary for these billets before the machining.In conventional localization methods,the design surface’s location focused on guaranteeing enough material to be cut.However,because the to-becut surface is in near-net and free-form shape,it is difficult to find a valid localized surface model to generate the tool path.Different from the localized surface is taken as rigid in previous investigation,it is allowed to deviate from the design surface no more than the tolerance band.In term of this principle,the tolerance band is utilized to promote localization ability.A series of optimization models with different priorities is established to avoid the abandonment expensive blade billet.Finally,with the experiments performed on the near-net-shape blades,the blade localization theory and the promotion of localization ability are verified. | Neng WAN Xiaogang SHEN Zhiyong CHANG Zezhong C.CHEN | 2021 | Chinese Journal of Aeronautics2021,34,6: | 0 |
| 19 | rDNA Sequencing and Preliminary Analysis of Microorganisms from Diseased Edible Fungus Using Non-culture Technology显示文摘The metagenomic DNA of disease tissue samples from four kinds of major edible fungus was extracted by CTAB method combined with DNA gel recovery kit. The genomic DNA was amplified by polymerase chain reaction using the universal primers of 16S rDNA and 18S rDNA,and then monoclonal sequenced after ligated and transformed. rDNA sequences of 20 positive clones were selected randomly from each pair of primers for sequence alignment. The results showed that there were two bacterial diseases and two fungal diseases in the samples,respectively. | Yao Qiang Gong Zhiyuan Gao Neng Han Jiandong Wan Luzhang Ren Pengfei Liu Xiao Huang Chunyan Ren Haixia | 2014 | Plant Diseases and Pests2014,5,1: | 0 |
