| 1 | A first-principles study of site occupancy and interfacial energetics of an H-doped TiAl-Ti_3 Al alloy显示文摘We investigate the site occupancy and the interfacial energetics of TiAl-Ti 3 Al binary-phase system with H using a first-principles method.H energetically prefers to occupy the Ti-rich octahedral interstitial site because H prefers to bond with Ti rather than with Al.The occupancy tendency of H in the binary phase TiAl-Ti 3 Al alloy from high to low is 2-Ti 3 Al to/2 interface and-TiAl,because the decrease of the Ti local concentration is in the same order.We demonstrate that H can largely affect the mechanical properties of the TiAl-Ti 3 Al system.On the one hand,H at the interface reduces the interface energy with the H 2 molecule as a reference,implying the TiAl/Ti 3 Al interface is stabilized.On the other hand,the ratio between the cleavage energy and the unstable stacking fault energy decreases after H-doping,indicating H will reduce the ductility of the TiAl/Ti 3 Al interface.Consequently,the mechanical property variation of TiAl alloy due to the presence of H not only depends on the amount of TiAl/Ti 3 Al interfaces but also is related to the H concentration in the alloy. | WEI Ye ZHANG Ying LU GuangHong XU HuiBin | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，2： | 8 |
| 2 | Label-free and real-time detection of antigen-antibody interactions by Oblique-incidence Reflectivity Difference(OIRD) method显示文摘We label-free and real-time detected three interaction processes of antigen-antibodies,Human Immunoglobulin G(IgG),Rabbit IgG,and Mouse IgG as the targets,and Goat Anti-human IgG,Goat Anti-rabbit IgG,and Goat Anti-mouse IgG as the probe,by the Oblique-incidence Reflectivity Difference(OIRD) method.The interaction dynamic curves of the OIRD signal,corresponding to the interaction processes of antigen-antibodies,are generated.The reaction times from beginning to equilibrium state are about 1800,900,and 1200 s for Human IgG,Rabbit IgG,and Mouse IgG,respectively.The experimental results demonstrate that the OIRD method not only can distinguish biomolecular interactions,but also can be used in real-time detection of interactions and dynamic processes of biomolecules. | HE LiPing SUN Yue DAI Jun WANG JingYi LU HuiBin WANG ShuFang JIN KuiJuan ZHOU YueLiang YANG GuoZhen | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，9： | 4 |
| 3 | A study on surface symmetry and interfacial enhancement of SrTiO_3 by second harmonic generation显示文摘The symmetry of the surfaces of SrTiO3and slightly Nb-doped SrTiO3crystals was investigated by the optical reflected second harmonic generation technique.The good agreement between experimental and theoretical results of the second harmonic intensity dependence on the azimuth angle indicates that the SrTiO3(001)surface is with 4mm symmetry and the Nb-doped SrTiO3(111)surface with 3m symmetry.The measurements of the polarization dependent second harmonic intensity confirm that conclusion.The enhancement of the surface polarization in the structure of SrTiO3capped La0.9Sr0.1MnO3films compared with that in the La0.9Sr0.1MnO3films has been obtained. | ZHAO RuiQiang JIN KuiJuan GUO HaiZhong LU HuiBin YANG GuoZhen | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，12： | 3 |
| 4 | Oxygen vacancy induced magnetism in BaTiO_(3-δ) and Nb:BaTiO_(3-δ) thin films显示文摘The unusual magnetic properties are observed in oxygen deficient BaTiO3-δ(BTO) and Nb:BaTiO3-δ(BNTO) thin films fabricated on SrTiO3 substrates by laser molecular beam epitaxy.The distinct magnetic hysteresis loops are observed in the oxygen deficient BTO and BNTO thin films in a temperature range of 5 to 300 K,whereas the diamagnetism is observed in both BTO and BNTO annealed at 1 atm of oxygen.The dopant Nb only enhances the magnetization in BNTO thin films,but has little effect on the coercivity.The magnetism of BTO and BNTO films is proposed to be the oxygen vacancies by origin. | YANG Fang,JIN KuiJuan,LU HuiBin,HE Meng,WANG Cong,WEN Juan & YANG GuoZhen Beijing National Laboratory for Condensed Matter Physics,Institute of Physics,Chinese Academy of Sciences,Beijing 100190,China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，5： | 3 |
| 5 | Identification of the metabolites of polybrominated diphenyl ether 99 and its related cytochrome P450s显示文摘Objective:To investigate the metabolites of polybrominated diphenyl ether 99(BDE-99)and its related cytochrome P450s in an in vitro system.Methods:Rat primary hepatocytes were isolated and treated with BDE-99 for 24-72 h.Metabolites were then extracted from the hepatocytes and media,and detected by GC/MS.Several mRNAs of metabolic enzymes were also extracted from the same cells and the gene expression levels were determined using quantitative real-time PCR.In addition,selected recombinant cytochrome P450s(CYPs) were expressed in a bacurovirus/sf9 system,and these were further used to explore the metabolism of BDE-99 in vitro.The parent depletion approach was used for screening the ability of CYPs to eliminate BDE-99.Results: A reductively debrominated metabolite,BDE-47,and three oxidative metabolites,2,4,5-tribromophenol,5-OH-BDE-47,and 5'-OH-BDE-99,were identified from the BDE-99-treated rat hepatocytes,whereas no MeO metabolite was detected in the system.RT-PCR analysis showed that CYP 3A23/3A1,1A2,and 2B1/2 were induced by BDE-99.Furthermore,using the heterological expressed CYP proteins in in vitro BDE-99 metabolism experiments we found that CYP1A2 and CYP3A4 showed the highest metabolic efficiency for BDE-99,with the metabolic clearance rates of CYP1A2 and CYP3A4 being 30.3%and 27.7%,respectively.CYP1A1 and CYP2A6 displayed relatively low clearance rates,while CYP2E1 seemed not to be associated with the BDE-99 metabolism.Conclusions:In our in vitro rat primary hepatocyte metabolism system,four metabolites of BDE-99 were identified,and CYP3A4 and CYP1A2 were demonstrated to be involved in the BDE-99 metabolism. | Huibin Dong Ziyin Li Xiaoming Man Jingping Zhou Huiyuan Lu Shoulin Wang | 2010 | The Journal of Biomedical Research2010，24，3： | 2 |
| 6 | Colossal magnetoresistance and spin-glass properties of La(1-x)TexMnO3(x=0.04,0.1)显示文摘For the first time, a novel material of La1-x- TexMnO3 (x = 0.04, 0.1), in which the La ions are replaced by the nonmetal element Te in the Chalcogen, has been synthesized. The material has a rhombohedral lattice with the space group of R3c, and Te ions have a tetravalence state. The curves of the resistivity vs. temperature indicate that this material has the property of a metal-semiconductor transition and the colossal magnetoresistance (CMR) effect. The maximum magnetoreistance ratio MR=[(0)()]/(0)H? is about 51% at 4 T for x = 0.1. Besides, a spin-glass behavior at low magnetic fields is observed in this compound. | TAN Guotai, DUAN Peng, DAI Shouyu, CHEN Zhenghao, LU Huibin & ZHOU Yueliang Laboratory of Optical Physics, Institute of Physics & Center for Condensed Matter Physics, Chinese Academy of Sciences, Beijing 100080, China Correspondence should be addressed to Chen Zhenghao (e-mail: zhchen @aphy.iphy.ac.cn) | 2003 | Chinese Science Bulletin2003，48，13： | 1 |

| 8 | Isothermal Oxidation Behavior of Dysprosium/S-Doped β-NiAl Alloys at 1200°C显示文摘A β-NiAl alloy with normal purity, a S-doped and a Dy and S co-doped b-NiAl alloys were prepared by arc-melting and their corresponding S contents were less than 20×10 6, 33×10-6 and 22×10-6, respectively. The isothermal oxidation behavior of the alloys at 1200° C was investigated and the extent of S segregation at the scalee alloy interface was determined by scanning Auger microscopy. S-doping had no significant effect on the phase transformation rate from q- to a-Al2O3, while the addition of Dy retarded this process. For the Sdoped alloy, scale rumpling occurred only after 2 h thermal exposure and numerous large voids were observed at the scalee alloy interface where S segregated. In contrast to this, the oxide scale formed on the Dy and S co-doped alloy still remained flat even after 50 h isothermal oxidation and only small voids existed at the interface where S segregation was not detected. | Lu Wang Dongqing Li Jian Chang Hongbo Guo Shengkai Gong Huibin Xu | 2014 | Journal of Materials Science & Technology2014，30，3： | 1 |
| 9 | Interfacial-Strain-Induced Structural and Polarization Evolutions in Epitaxial Multiferroic BiFeO_3(001) Thin Films显示文摘Varying the film thickness is a precise route to tune the interfacial strain to manipulate the properties of the multiferroic materials.Here,to explore the effects of the interfacial strain on the properties of the multiferroic BiFeO_3films,we investigated thickness-dependent structural and polarization evolutions of the BiFeO_3 films.The epitaxial growth with an atomic stacking sequence of BiO/TiO_2 at the interface was confirmed by scanning transmission electron microscopy.Combining X-ray diffraction experiments and first-principles calculations,a thickness-dependent structural evolution was observed from a fully strained tetragonality to a partially relaxed one without any structural phase transition or rotated twins.The tetragonality(c/a) of the BiFeO_3 films increases as the film thickness decreases,while the polarization is in contrast with this trend,and the size effect including the depolarization field plays a crucial role in this contradiction in thinner films.These findings offer an alternative strategy to manipulate structural and polarization properties by tuning the interfacial strain in epitaxial multiferroic thin films. | 郭海中 Ruiqiang Zhao Kui-juan Jin Lin Gu Dongdong Xiao Zhenzhong Yang Xiaolong Li Le Wang Xu He Junxing Gu Qian Wan Can Wang Huibin Lu Chen Ge Meng He Guozhen Yang | 2015 | 功能材料信息2015，12，3： | 1 |

| 11 | High sensitive and ultrafast UV photodetector based on ZrO_2 single crystals显示文摘The fast-response ultraviolet (UV) photoelectric effect in ZrO2 single crystals with interdigitated electrodes has been investigated experimentally at room temperature. The photovoltage of ZrO2 single crystals exhibits a linear dependence on applied bias and light power density. The photocurrent responsivity to the UV light with a wavelength of 253.65 nm is 9.8 mA/W. For the photovoltaic pulse, a rise time of 501 ps and a full width at half maximum of 1.5 ns have been obtained, when the ZrO2 single crystal is illuminated by a 266 nm pulsed laser. These results indicate that the ZrO2 single crystal is a promising candidate for UV photodetectors. | XING Jie GUO ErJia LU HuiBin | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，8： | 1 |

| 13 | Low-field positive and high-field negative magneto-resistances in multiphase Fe-oxide thin films at room temperature显示文摘Multiphase Fe-oxide thin films are fabricated on glass substrates by a facing-target sputtering tech- nique. X-ray diffraction and X-ray photoelectron spectroscopy reveal that Fe, Fe3BO4, γ -Fe2BO3B and FeO coexist in the films. High resolution transmission electron microscopy shows the well-defined colum- nar grain structure with the unoxidized Fe as the core and iron-oxide as the shell. The low-field positive and high-field negative magnetoresistances coexist in such a system at room temperature, which can be explained by considering a shell/core model. Nonlinear current-voltage curve and photovoltaic effect further confirm the tunneling-type conduction. | ZHAO Kun XING Jie LIU YuZi ZHAO JianGao LU HuiBin | 2007 | Chinese Science Bulletin2007，52，12： | 1 |

| 16 | High resistance modulation by the electric field based on La_(0.9)Sr_(0.1)MnO_3/SrTiO_3/Si structure显示文摘A field-effect configuration based on La0.9Sr0.1MnO3/SrTiO3/Si structure is fabricated on Si substrate by laser molecular-beam epitaxy. The resistance modulation by electric field of the La0.9Sr0.1MnO3/SrTiO3/Si structure is investigated in detail. An evident resistance modulation effect is observed at 80 K. The channel resistance modulation by field effect reaches 1.4×107% and 2.6×106% when VDS are -2 and -6.5 V, respectively. The ON/OFF ratio of approximately 4000 is obtained. The present results are worthy of further investigations for potential applications of resistance modulation by electrostatic field in the heterostructures consisting of perovskite oxides and Si. | YANG Fang, HE Meng, WEN Juan, JIN KuiJuan, LU HuiBin & YANG GuoZhen Beijing National Laboratory for Condensed Matter Physics, Institute of Physics, Chinese Academy of Sciences, Beijing 100190, China | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，9： | 1 |

| 19 | A VERSATILE CURRENT-MODE BIQUAD USING OPERATIONAL AMPLIFIERS显示文摘A versatile current-mode biquadratic filter using three operational amplifiers and nine passive elements is proposed. By suitably choosing the output branch, lowpass, bandpass, highpass, bandstop and allpass transfer functions are realized simultaneously without changing the circuit configuration and elements. Two circuits, one is for low frequency application and the other for high frequency, are proposed. The center frequency, quality factor and gain constants of the circuit can be tuned independently. Simulated results show that the circuits work successfully. | Yuan Shiwen Lu Huibin Shi Weidong Yutaka Fukui(Yanshan University, Qinhuangdao 066004) (Tottori University, Koyama, Tottori, 680 Japan) | 1999 | Journal of Electronics(China)1999，16，1： | 0 |
| 20 | Oxygen vacancies effects on phase diagram of epitaxial La1-xSrxMnO3 thin films显示文摘We investigated the effects of oxygen vacancies on the structural,magnetic,and transport properties of La_(1-x)Sr_xMnO_3(x=0.1,0.2,0.33,0.4,and 0.5)grown around a critical point(without/with oxygen vacancies)under low oxygen pressure(10 Pa)and high oxygen pressure(40 Pa).We found that all films exhibit ferromagnetic behavior below the magnetic critical temperature,and that the films grown under low oxygen pressures have degraded magnetic properties with lower Curie temperatures and smaller magnetic moments.These results show that in epitaxial La_(1-x)Sr_xMnO_3 thin films,the magnetic and transport properties are very sensitive to doping concentration and oxygen vacancies.Phase diagrams of the films based on the doping concentration and oxygen vacancies were plotted and discussed. | Qian Wan KuiJuan Jin QingQing Li YaQing Feng Can Wang Chen Ge Meng He HuiBin Lu HaiZhong Guo XiaoLong Li YuPing Yang GuoZhen Yang | 2017 | Science China(Physics,Mechanics & Astronomy)2017，60，5： | 0 |
