| 1 | Organochlorine compounds and polycyclic aromatic hydrocarbons in surface sediment from Baiyangdian Lake,North China:Concentrations,sources profiles and potential risk显示文摘Organochlorine pesticides(OCPs),polychlorinated biphenyls(PCBs),and polycyclic aromatic hydrocarbons(PAHs) were determined in nineteen surface sediment samples collected from Baiyangdian Lake and its inflowing river(Fuhe River) in North China.Total concentrations of OCPs,PCBs and PAHs in sediments ranged from 5.4 to 707.6 ng/g,2.3 to 197.8 ng/g,and 101.3 to 6360.5 ng/g,respectively.The levels of contaminants in Fuhe River were significantly higher than those in Baiyandian Lake.For hexachlorocyclohexane(HCHs) and dichlorodiphenytrichloroethanes(DDTs),α-HCH and p,p-DDT were predominant isomers;while for PCBs,PCB 28/31,PCB 40/103,PCB 60,PCB 101,and PCB 118 were predominant congeners.Possible sources derived from historical usage for OCPs and incomplete combustion fuel,wood,and coal and exhaustion of boats or cars for PAHs.Risk assessment of sediment indicated that sediments in Fuhe River were likely to pose potential biological adverse impact. | Guocheng Hu Xiaojun Luo Fengchao Li Jiayin Dai Jianyang Guo Shejun Chen Cao Hong Bixian Mai Muqi Xu | 2010 | Journal of Environmental Sciences2010，22，2： | 42 |

| 3 | Ab initio study of the effects of Ag/Mn doping on the electronic structure of LiFePO_4显示文摘Based on density functional theory (DFT) of the first-principle for the cathode materials of lithium ion battery, the electronic structures of Li(Fe1-xMex)PO4 (Me = Ag/Mn, x = 0―0.40) are calculated by plane wave pseudo-potential method using Cambridge serial total energy package (CASTEP) program. The calculated results show that the Fermi level of mixed atoms Fe1-xAgx moves into its conduction bands (CBs) due to the Ag doping. The Li(Fe1-xAgx)PO4 system displays the periodic direct semiconductor characteristic with the increase of Ag-doped concentration. However, for Fe1-xMnx mixed atoms, the Fermi level is pined at the bottom of conduction bands (CBs), which is ascribed to the interaction be-tween Mn(3d) electrons and Fe(4s) electrons. The intensity of the partial density of states (PDOS) near the bottom of CBs becomes stronger with the increase of Mn-doped concentration. The Fermi energy of the Li(Fe1-xMnx)PO4 reaches maximum at x = 0.25, which is consistent with the experimental value of x = 0.20. The whole conduction property of Mn-doped LiFePO4 is superior to that of Ag-doped LiFePO4 cathode material, but the structural stability is reverse. | HOU XianHua HU SheJun LI WeiShan ZHAO LingZhi RU Qiang YU HongWer HUANG ZhaoWen | 2008 | Chinese Science Bulletin2008，53，11： | 9 |
| 4 | Lithium intercalation/de-intercalation behavior of a composite Sn/C thin film fabricated by magnetron sputtering显示文摘A tin film of 320 nm in thickness on Cu foil and its composite film with graphite of ~50 nm in thickness on it were fabricated by magnetron sputtering. The surface morphology, composition, surface distributions of alloy elements, and lithium intercalation/de-intercalation behaviors of the fabricated films were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), electron probe microanalyzer (EPMA), X-ray photoelectron spectroscopy (XPS), inductively coupled plasma atomic emission spectrometry (ICP), cyclic voltammetry (CV), and galvanostatic charge/discharge (GC) measurements. It is found that the lithium intercalation/de-intercalation behavior of the Sn film can be significantly improved by its composite with graphite. With cycling, the discharge capacity of the Sn film without composite changes from 570 mAh/g of the 2nd cycle to 270 mAh/g of the 20th cycle, and its efficiency for the discharge and charge is between 90% and 95%. Nevertheless, the discharge capacity of the composite Sn/C film changes from 575 mAh/g of the 2nd cycle to 515 mAh/g of the 20th cycle, and its efficiency for the discharge and charge is between 95% and 100%. The performance improvement of tin by its composite with graphite is ascribed to the retardation of the bulk tin cracking from volume change during lithium intercalation and de-intercalation, which leads to the pulverization of tin. | ZHAO Lingzhi HU Shejun LI Weishan LI Liming HOU Xianhua | 2008 | Rare Metals2008，27，5： | 8 |
| 5 | Dead lithium phase investigation of Sn-Zn alloy as anode materials for lithium ion battery显示文摘In this work, based on First-principle plane wave pseudo-potential method, we have carried out an in-depth study on the possible dead lithium phase of Sn-Zn alloy as anode materials for lithium ion batteries. Through investigation, we found that the phases LixSn4Zn4(x = 2, 4, 6, 8) contributed to re-versible capacity, while the phases LixSn4Zn8-(x-4)(x = 4.74, 7.72) led to capacity loss due to high forma-tion energy, namely, they were the dead lithium phases during the charge/discharge process. And we come up with a new idea that stable lithium alloy phase with high lithiation formation energy (dead lithium phase) can also result in high loss of active lithium ion, besides the traditional expression that the formation of solid electrolyte interface film leads to high capacity loss. | HUANG ZhaoWen HU SheJun HOU XianHua RU Qiang YU HongWen ZHAO LingZhi LI WeiShan | 2009 | Chinese Science Bulletin2009，54，6： | 6 |
| 6 | Effects of Ti_(0.5)Al_(0.5)N coatings on the protecting against oxidation for titanium alloys显示文摘Ti0.5Al0.5N coatings were deposited on TC11(Ti-6.5Al-3.5Mo-1.5Zr-0.3Si) and silicon substrates using a cathode arc ion-plating system.The microstructure, composition, phase structure, and oxidation-resistance of the alloys and nitride coatings were investigated by scanning electron microscopy, X-ray diffraction, transmission electron microscopy, Auger electron spectroscopy, and thermal analyzer.The results show that the oxidation resistance of the titanium alloy is relatively limited;the compound structures of Ti mixed with Al oxides are formed during the heating process.The phases of the Ti0.5Al0.5N coatings are composed of a TiN solid solution phase.The oxidation kinetics obeys the parabolic law.During the oxidation process, the selective oxidation of Al occurs, thus protecting the underlying coating and substrate. | RU Qiang HU Shejun | 2010 | Rare Metals2010，29，2： | 6 |
| 7 | TiO_2-coated SnO_2 hollow spheres as anode materials for lithium ion batteries显示文摘TiO2-coated SnO2(TCS) hollow spheres,which are new anode materials for lithium ion(Li-ion) batteries,were prepared and characterized with X-ray diffraction(XRD) ,scanning electron microscopy(SEM) ,transmission electron microscopy(TEM) ,cyclic voltammetry(CV) ,and galvanostatic charge/discharge tests.The results obtained from XRD,SEM,and TEM show that TiO2 can be uniformly coated on the surface of SnO2 hollow spheres with the assistance of anionic surfactant.The cyclic voltammograms indicate that both TiO2 and SnO2 ex-hibit the activity for Li-ion storage.The charge/discharge tests show that the prepared TCS hollow spheres have a higher reversible coulomb efficiency and a better cycling stability than the uncoated SnO2 hollow spheres. | YI Jin LI Xiaoping HU Shejun LI Weishan ZENG Ronghua FU Zhao CHEN Lang | 2011 | Rare Metals2011，30，6： | 4 |
| 8 | First principles studies on the electronics structures of(Li_(1-x)Me_x)FePO_4(Me=Na and Be)显示文摘Based on density functional theory(DFT)of the first-principle for cathode materials of lithium ion battery,the electronic structures of(Li1-xMex)FePO4(Me=Na and Be,x=0-0.40)are calculated by plane wave pseudo-potential method using Cambridge serial total energy package(CASTEP)program.The calculated results show that Li-site doping can improve the electronic conductivity enormously.Doping with Na has a noticeable effect on improving its electrical conductivity.However,serious structural distortion will occur when its doping density is beyond 0.25.In view of this,the best density of doping Na is less than 0.25.Doping with Be has an inconspicuous effect on increasing its electrical conductivity and has good cyclical stability,but it cannot achieve as good results as when it is doped with Na.Therefore we cannot find a middle ground between the two proposals.Considering cost and environmental protection,it is ideal to choose Na.So this method gives a reasonable prediction to the improvement of electronic conductivity through Li-site doping in LiFePO4 material. | HOU XianHua HU SheJun | 2010 | Chinese Science Bulletin2010，55，27： | 4 |
| 9 | First-principles calculations and experimental studies of Sn-Zn alloys as negative electrode materials for lithium-ion batteries显示文摘The physical characters and electrochemical properties of various phases in a Sn-Zn electrode,such as formation energy,plateau potential,specific capacity,as well as volume expansion,were calculated by the first-principles plane-wave pseudo-potential method based on the density functional theory.Sn-Zn films were also deposited on copper foils by an electroless plating technique.The actual composition and chemical characters were explored by scanning electron microscopy (SEM),X-ray diffraction (XRD),plasma atomic emission spectrometry (ICP),and constant current charge/discharge measurements (CC).The results show that separation phases with tin and zinc including a small quantity of Cu6Sn5 phase were obtained,the initial lithium insertion capacity of the Sn-Zn film was 661 mAh/g,and obvious potential plateaus of about 0.4 V and 0.7 V were displayed,which is in accordance with the results of theoretical calculations.The capacity of the Sn-Zn film decreased seriously with the increase of cycle number. | RU Qiang PENG Wei ZHANG Zhiwen HU Shejun LI Yanling | 2011 | Rare Metals2011，30，2： | 3 |

| 11 | Effect of Annealing Temperature on GMR of [NiFeCo(10 nm)/Ag(10 nm)]×20 Multilayer Film显示文摘The composition, phase structure, and microstructure of the discontinuous multilayer films [NiFeCo(10 nm)/Ag(10 nm)]×20 annealed at temperature 280,320,360 and 400℃, respectively were investigated. GMR (giant magnetoresistance) ratios of the multilayer films were measured at different temperatures. The results showed that FeNia precipitated at 360℃ and dissolved at 400℃. The films annealed at 360℃ for I h exhibited the highest GMR ratio 11% when saturation field was equal to 79.6 kA/m. | Yuding HE, Shejun HU, Jian LI and Guangrong XIECollege of Material and Energy, Guangdong University of Technology, Guangzhou 510643, China | 2004 | Journal of Materials Science & Technology2004，20，2： | 1 |

| 13 | First-principle study on NiSn_(0.5)Ti_(0.5) phase as electrode materials for lithium ion battery显示文摘The electronic structure and electrochemical parameters of ternary NiSn0.5Ti0.5 phase are investigated by plane-wave pseudopotential method of the first-principle.The interstitial sites are firstly filled with lithium atoms,and then the substitution for Ni sites occurs.The results show that the Fermi level of lithium-intercalated phase goes up with the increasing lithium concentration.These interactions of M-M covalent bonds (M=Ni,Sn,Ti) become weak,while Li-M bonds are found to increase.NiSn 0.5Ti0.5 phase is characterized with high theoretical capacity and low voltage of lithium-intercalation.The obvious volume effect from 77.15%to 189.94% would lead to the failure of the electrode material,and therefore the NiSn0.5Ti0.5 compound should be limited as low as possible in multi-element Sn-based alloy. | RU Qiang HU SheJun ZHANG ZhiWen PENG Wei HOU XianHua HUANG ZhaoWen | 2010 | Chinese Science Bulletin2010，55，27： | 1 |

| 15 | Facile hydrothermal and sol-gel synthesis of novel Sn-Co/C composite as superior anodes for Li-ion batteries显示文摘As an anode material in lithium ion battery,the Sn-Co/C composite electrode materials have been successfully synthesized by hydrothermal and sol-gel methods,respectively.The resultant composites were mainly composed of Sn-based oxides,nanometer Sn-Co alloy and carbon.Carbon and Co,acting as buffer materials,can accommodate to the large volume change of active Sn during the discharge-charge process,thus improving the cycling stability.Although charge/discharge curves revealed the excellent cycle performance for samples synthesized by both methods,composites obtained by the sol-gel showed a better dispersion effect of nanoparticles on the carbon matrix and possessed much more improved stable capacity with*624.9 mAh g-1over 100 cycles and that by hydrothermal method only exhibited*299.3 mAh g-1.Therefore,the Sn-Co/C composites obtained by sol-gel synthesis method could be a perfect candidate for anode material of Li-ion storage battery. | Xiaoli Zou Xianhua Hou Zhibo Cheng Yanling Huang Min Yue Shejun Hu | 2014 | Chinese Science Bulletin2014，59，23： | 1 |

| 18 | Structure and electrochemical properties of hypo-stoichiometric hydro-gen storage alloys prepared by twin-roller rapid quenching process显示文摘The stoichiometric alloy MlB5.0 and the hypo-stoichiometric alloy MlB4.85 were prepared by twin-roller rapid quenching process, and their structure and electrochemical properties were studied. The results of XRD show that both of the alloys have a typical single-phase hexagonal CaCu5-type structure. The cell volume of the hypo-stoichiometric alloy MlB4.85 is slightly larger than that of the stoichiometric alloy MlB5.0, although its lattice constant c/a is smaller. Under 2 C discharging rate, i.e. 640 mA/g, the MlB4.85 has a discharge capacity of 320 mAh/g, which is higher than that of the MlB5.0, 312 mAh/g. Nevertheless, the capacities of the MlB4.85 and the MlB5.0 decline 24.7% and 20.2% after 400 cycles, respec- tively. The relationship of electrochemical performances of the alloys with their structures is discussed. | ZHOU Liu LU Dongsheng LI Weishan HU Shejun CAI Yuepeng TANG Renheng XIAO Fangming | 2005 | Rare Metals2005，24，4： | 1 |
| 19 | Preparation and characterization of TiO_2 photoelectrode codoped with aluminum and boron and its application in dye-sensitized solar cell显示文摘Nanocrystalline titania films codoped with aluminum and boron were prepared by cathodic vacuum arc deposition. In the process, titanium alloy target was used under an O2/Ar atmosphere, and sensitization of films were carried out by natural dye-sensitized complex in anhydrous ethanol. The structure, surface morphology and UV-vis spectra of titania films codoped were measured by X-ray diffraction analysis, scanning electron microscopy and ultraviolet-visible spectrometer. The as-deposited films are found to be amorphous. The films annealed were examined to be of anatase structure with orientation along the (101) planes, the average crystal size is in the range between 41 and 45 nm. SEM results show that there are some pores in the codoped titania films, the optical properties of the dye-sensitized films were also measured which reveals that the spectral responses of films shift to the visible region. Under simulated sunlight illumination, the overall energy conversion efficiency of dye-sensitized nanocrystalline solar cell is 0.9%. | CHENG Xiaoling ZENG Peng HU Shejun KUANG Tongchun XIE Guangrong GAO Feng | 2006 | Rare Metals2006，25，z1： | 0 |
| 20 | Hierarchically 3D structured milled lamellar MoS2/nano-silicon@carbon hybrid with medium capacity and long cycling sustainability as anodes for lithium-ion batteries显示文摘A hierarchically 3D structured milled lamellar MoS2/nano-siIicon@carbon hybrid with medium capacity and long-term lifespan is designed by a green and scalable approach using ball milling process and spraydrying/ pyrolysis routes. The microspheres consist of low-content nano-silicon (20 wt%), milled lamellar M0S2 sheets and porous carbon skeletons. A mixture of silicon nanoparticles and M0S2 flakes serves as an inner core, while porous carbon pyrolyzed from petroleum pitch acts as a protective shell. The particular architecture affords robust mechanical support, abundant buffering space and enhanced electrical conductivity, thus effectively accommodating drastic volume variation during repetitive Li+ intercalation/ extraction. The Si/MoS2@C hybrid delivers a high initial discharge specific capacity of 1257.8 mA hg^-1 and exhibits a reversible capacity of 767.52 m A hg^-1 at a current density 100 mA g'1 after 250 cycles. Most impressively, the electrode depicts a superior long-cycling durability with a discharge capacity of 537.6 mA hg^-1 even after 1200 cycles at a current density of 500 m A g^-1. Meanwhile, the hybrid also shows excellent rate performance such as 388.1 mA h g^-1 even at a large current density of 3000 mA g^-1. | Peng Zhang Qiang Rua Honglin Yan Xianhua Hou Fuming Chen Shejun Hu Lingzhi Zhao | 2019 | Journal of Materials Science & Technology2019，35，9： | 0 |
