| 1 | Effects of particle composition and environmental parameters on catalytic hydrodechlorination of trichloroethylene by nanoscale bimetallic Ni-Fe显示文摘Catalytic nickel was successfully incorporated into nanoscale iron to enhance its dechlorination efficiency for trichloroethylene(TCE), one of the most commonly detected chlorinated organic compounds in groundwater. Ethane was the predominant product. The greatest dechlorination efficiency was achieved at 22 molar percent of nickel. This nanoscale Ni-Fe is poorly ordered and inhomogeneous; iron dissolution occurred whereas nickel was relatively stable during the 24-hr reaction. The morphological characterization provided significant new insights on the mechanism of catalytic hydrodechlorination by bimetallic nanoparticles. TCE degradation and ethane production rates were greatly affected by environmental parameters such as solution pH, temperature and common groundwater ions. Both rate constants decreased and then increased over the pH range of 6.5 to 8.0, with the minimum value occurring at pH 7.5. TCE degradation rate constant showed an increasing trend over the temperature range of 10 to 25?C. However, ethane production rate constant increased and then decreased over the range, with the maximum value occurring at 20?C. Most salts in the solution appeared to enhance the reaction in the first half hour but overall they displayed an inhibitory effect. Combined ions showed a similar effect as individual salts. | Jianjun Wei Yajing Qian Wenjuan Liu Lutao Wang Yijie Ge Jianghao Zhang Jiang Yu Xingmao Ma | 2014 | Journal of Environmental Sciences2014，26，5： | 9 |
| 2 | Effect of rich R-TiO2 on the rate and cycle properties of Li4Ti5O12 as anode for lithium ion batteries显示文摘Li4Ti5012 (LTO) with rich R-TiO2 (17.06, 23.69, and 34.42 wt%), namely, R-TiO2@Li4Ti5O12 composites, were synthesized using the hydrothermal method and tetrabutyl titanate (TBT) as the precursor. Rietveld refinement of X-ray diffraction (XRD) results show that the proportion of Li occupying 16d sites is extraordinary low and the lattice constants of LTO and R-TiO2 change with the ritanium dioxide content. EIS measurements showed that with in creasing R-TiO2 content, both its charge transfer impedance (Rct) and lithium ion diffusion coefficient (DLi) decreased. The changes of Rct and DLi caused by the increase of titanium dioxide content have synergic-antagonistic effects on the rate and cycle properties of Li4Ti5012. The rate performance is positively related to DLi, while the cycle property is negatively correlated with Rct, indicati ng that the rate performs nee is mainly related to DLi, while Rct more significantly affects the cycle performance. LTO-RT-17.06% exhibited excellent rate properties, especially under a high current density (5.0 C, 132.5 mAh/g) and LTO-RT-34.42% showed superior long-term cycle performance (0.012% capacity loss per cycle) compared to that of LTO-RT-17.06% and LTO-RT-23.69%. | Delai Qian Yijie Gu Shuainan Guo Hongquan Liu Yunbo Chen Juan Wang Guoxuan Ma Chuan Wu | 2019 | Journal of Energy Chemistry2019，28，5： | 3 |
| 3 | Distribution and spectral characteristics of chromophoric dissolved organic matter in a coastal bay in northern China显示文摘The absorption spectra of chromophoric dissolved organic matter(CDOM),along with general physical,chemical and biological variables,were determined in the Bohai Bay,China,in the springs of 2011 and 2012. The absorption coefficient of CDOM at 350 nm(a350) in surface water ranged from 1.00 to 1.83 m-1(mean: 1.35 m-1) in May 2011 and from 0.78 to 1.92 m-1(mean:1.19 m-1) in April 2012. Little surface-bottom difference was observed due to strong vertical mixing. The a350 was weakly anti-correlated to salinity but positively correlated to chlorophyll a(Chl-a) concentration. A shoulder over 260–290 nm,suggestive of biogenic molecules,superimposed the overall pattern of exponentially decreasing CDOM absorption with wavelength. The wavelength distribution of the absorption spectral slope manifested a pronounced peak at ca. 300 nm characteristic of algal-derived CDOM. All a250/a365 ratios exceeded 6,corresponding to CDOM molecular weights(Mw) of less than 1 kDa. Spectroscopically,CDOM in the Bohai Bay differed substantively from that in the Haihe River,the bay's dominant source of land runoff; photobleaching of the riverine CDOM enlarged the difference.Results point to marine biological production being the principal source of CDOM in the Bohai Bay during the sampling seasons. Relatively low runoff,fast dilution,and selective photodegradation are postulated to be among the overarching elements responsible for the lack of terrigenous CDOM signature in the bay water. | Guiju Li Jing Liu Yulan Ma Ruihua Zhao Suzheng Hu Yijie Li Hao Wei Huixiang Xie | 2014 | Journal of Environmental Sciences2014，26，8： | 2 |
| 4 | Feverfew: a scalable coverage-based hybrid overlay for Internet-scale pub/sub networks显示文摘The publish/subscribe(pub/sub)paradigm is a popular communication model for data dissemination in large-scale distributed networks.However,scalability comes with a contradiction between the delivery latency and the memory cost.On one hand,constructing a separate overly per topic guarantees real-time dissemination,while the number of node degrees rapidly increases with the number of subscriptions.On the other hand,maintaining a bounded number of connections per node guarantees small memory cost,while each message has to traverse a large number of uninterested nodes before reaching the subscribers.In this paper,we propose Feverfew,a coverage-based hybrid overlay that disseminates messages to all subscribers without uninterested nodes involved in,and increases the average number of node connections slowly with an increase in the number of subscribers and nodes.The major novelty of Feverfew lies in its heuristic coverage mechanism implemented by combining a gossip-based sampling protocol with a probabilistic searching protocol.Based on the practical workload,our experimental results show that Feverfew significantly outperforms existing coverage-based overlay and DHT-based overlay in various dynamic network environments. | MA XingKong WANG YiJie SUN WeiDong | 2014 | Science China(Information Sciences)2014，57，5： | 1 |

| 15 | Engineering Sodium Metal Anode with Sodiophilic Bismuthide Penetration for Dendrite-Free and High-Rate Sodium-Ion Battery显示文摘Sodium(Na)metal batteries with a high volumetric energy density that can be operated at high rates are highly desirable.However,an uneven Na-ion migration in bulk Na anodes leads to localized deposition/dissolution of sodium during high-rate plating/stripping behaviors,followed by severe dendrite growth and loose stacking.Herein,we engineer the Na hybrid anode with sodiophilic Na_(3)Bi-penetration to develop the abundant phase-boundary ionic transport channels.Compared to intrinsic Na,the reduced adsorption energy and ion-diffusion barrier on Na_(3)Bi ensure even Na^(+)nucleation and rapid Na^(+)migration within the hybrid electrode,leading to uniform deposition and dissolution at high current densities.Furthermore,the bismuthide enables compact Na deposition within the sodiophilic framework during cycling,thus favoring a high volumetric capacity.Consequently,the obtained anode was endowed with a high current density(up to 5 mA∙cm^(−2)),high areal capacity(up to 5 mA∙h∙cm^(−2)),and long-term cycling stability(up to 2800 h at 2 mA∙cm^(−2)). | Wanyu Zhao Min Guo Zhijun Zuo Xiaoli Zhao Huanglin Dou Yijie Zhang Shiying Li Zichen Wu Yayun Shi Zifeng Ma Xiaowei Yang | 2022 | Engineering2022，8，4： | 0 |
| 16 | A new method to prepare calcium oxalate films for marble protection显示文摘Artificial calcium oxalate films have been applied to protect sculptures,monuments,and buildings made of marble due to their potential protective capacities.Unfortunately,artificially prepared calcium oxalate films are usually loose,and easy to peel off in contrast to the natural ones.In this paper,a new method was developed for the preparation of a compact and cohesive calcium oxalate film,using ethylene glycol as an additive.The morphology,elemental composition,structure,and crystal phase of the film were analyzed by SEM,EDX,IR,and XRD,and the protective effects were investigated by acid resistance test,while its adhesion to the underlying marble by the Scotch tape test.The porosity,water absorption,and color of treated marble were also assessed.The results showed that a calcium oxalate film with a compact structure,good adhesion,and a protective effect against acid rain can be successfully obtained by including ethylene glycol as an additive.With the new preparation method,a better bond between the stone and the film is obtained which contributes to solving the spalling problem of the artificial calcium oxalate films. | HE Lu JIANG YiJie MA WenTing LIU Yan YANG FuWei LU RuiCong WANG Lu ZHANG Kun CHEN XinNan GAO Xiang | 2023 | Science China(Technological Sciences)2023，66，8： | 0 |
| 17 | Realizing n-type CdSb with promising thermoelectric performance显示文摘Realizing high performance in both n-type and p-type materials is essential for designing efficient ther-moelectric devices.However,the doping bottleneck is often encountered,i.e.,only one type of conduction can be realized.As one example,p-type CdSb with high thermoelectric performance has been discovered for several decades,while its n-type counterpart has rarely been reported.In this work,the calculated band structure of CdSb demonstrates that the valley degeneracy is as large as ten for the conduction band,and it is only two for the valence band.Therefore,the n-type CdSb can potentially realize an ex-ceptional thermoelectric performance.Experimentally,the n-type conduction has been successfully real-ized by tuning the stoichiometry of CdSb.By further doping indium at the Cd site,an improved room-temperature electron concentration has been achieved.Band modeling predicts an optimal electron con-centration of∼2.0×1019 cm−3,which is higher than the current experimental values.Therefore,future optimization of the n-type CdSb should mainly focus on identifying practical approaches to optimize the electron concentration. | Peng Zhao Honghao Yao Shizhen Zhi Xiaojing Ma Zuoxu Wu Yijie Liu Xinyu Wang Li Yin Zongwei Zhang Shuaihang Hou Xiaodong Wang Siliang Chen Chen Chen Xi Lin Haoliang Liu Xingjun Liu Feng Cao Qian Zhang Jun Mao | 2023 | Journal of Materials Science & Technology2023，，13： | 0 |
| 18 | Application of different molecular sieves in photothermal catalysis of Jatropha oil显示文摘The preparation of green and economical bio-aviation fuel is a priority for the sustainable development industry.In this study,Jatropha oil was used as a raw material to catalyze the conversion of raw material to aviation kerosene fraction by photothermal coupling under the conditions of light and low temperature.The correlations among conversion rate,target alkane selectivity,composition distribution,and catalyst microstructure were investigated by X-ray diffraction(XRD),high-resolution transmission electron microscopy(HRTEM),nitrogen(N2)adsorption and desorption,X-ray fluorescence(XRF),ammoniatemperature programmed desorption(NH3-TPD),ultraviolet-visible spectrophotometry(UV-Vis),and other characterization.The correlation between conversion and target alkane selectivity and composition distribution and catalyst microstructure was investigated,and different modification methods and different molecular sieve materials were selected.The results showed that the molecular sieves modified with the solid dispersion method could retain the structural stability of titanium dioxide(TiO2)and molecular sieves to a great extent while slightly enhancing the pore capacity and pore size of the catalyst to make it easier to adsorb reactants;the introduction of active metal platinum(Pt)could reduce the forbidden bandwidth of the catalyst,increase the weak acid amount of the catalyst,improve the adsorption capacity of hydrogen(H2),and thus improve the catalytic ability,resulting in a suitable catalyst for this study:P-21.The photothermal catalytic reaction of Jatropha oil using P-21 catalyst obtained 97.21%conversion and 74.99%selectivity of the target alkanes under the optimal process parameters.The results of this study provide effective catalyst parameters for research in the field of clean energy. | Yijie Yang Longlong Ma Lumin Sun Xinghua Zhang Chao Gui Yubao Chen | 2023 | International Journal of Agricultural and Biological Engineering2023，16，5： | 0 |
| 19 | New Insights of Neuromedin B and Its Receptor NMBR Involvement in Immunity显示文摘Neuromedin B(NMB)is a member of mammalian bombesin-like peptide family and almost all its potent biological actions take place exclusively through its receptor NMBR,which has been identified as a G-protein couple receptor with seven trans-membrane regions.NMB and NMBR represent an interesting signaling axis over which NMB/NMBR perform multiple biological activities,in particularly,they have been highlighted in the regulation of the immunology system.This review aims to provide a brief overview of the recent advancements in our understanding regarding the potential immunological functions of NMB and NMBR in cell proliferation,tumorigenesis,angiogenesis,neurogenic inflammation,anti-influenza A virus(IAV)infections,and briefly discusses the potential importance of these observations.All these implicated that targeting NMBR or developing analogues of NMB may represent a useful strategy for development of new anti-IAV agents. | Chunyu LI Yijie MA Shimao TIAN Qianhui WAN Mengyao TANG Hongya NING Shujie MA Guihong YANG | 2021 | Asian Agricultural Research2021，13，6： | 0 |
| 20 | From microstructure evolution to thermoelectric and mechanical properties enhancement of SnSe显示文摘Defect existing form and its evolution play an important role in the thermoelectric transport process. Here different forms of Pb into the Sn Se system were introduced in order to improve the thermoelectric and mechanical properties of Sn Se. Pb/Sn Se samples were fabricated by vacuum melting, solid phase diffusion,spark plasma sintering and annealing treatment. The element valence mapping diagram and the X-ray photoelectron spectra(XPS) characteristic peaks of Pb show that a certain amount of elemental Pb exists in the initial state, and evolves into Pb^(2+)ion after annealing treatment. The micro-structure evolution leads to significant enhancement of the power factor and the ZT value. The power factor(PF) and the ZT value for Pb/Sn Se increases to 623 μW/m/K^(2) and 1.12 at 773 K after annealing treatment, respectively.Compared with Sn Se matrix, the hardness and fracture toughness of Pb/Sn Se samples increased by about40% and 10%, respectively. Reasonable control of microstructure evolution is expected to be a design idea to improve thermoelectric and mechanical properties of Sn Se. | Chi Ma Xue Bai Qiang Ren Hongquan Liu Yijie Gu Hongzhi Cui | 2020 | Journal of Materials Science & Technology2020，58，23： | 0 |
