| 1 | Liquid Crystal Motion Picture Projector显示文摘LiquidCrystalMotionPictureProjector①SHIYongji(LuoyangTechnologyColege,Luoyang471003,CHN)Abstract:Aliquidcrystalmovingpicturep... | SHI Yongji(Luoyang Technology College,Luoyang 471003,CHN)Abstract: A liquid crystal moving picture projector and method are described.Light incident on a liquid crystal display-type device is selectively scattered or transmitted by respective portions of liquid crystal display,and a projection mechanism projects an image formed by either such scattered light or such transmitted light.A liquid crystal moving picture projector includes a liquid crystal display for creating characteristics of an image,and projecttion optics for projecting images sequentially created by the display.The display includes a liquid crystal material capable of temporary storing information at respective areas.The temporary storage may be a function of charge storing directly on liquid crystal material.A method of projecting plural images in sequence includes:creating an image or characteristics of an image in a liquid crystal material,storing such image in such liquid crystal material,directing light at such liquid crystal material,projecting such image as a function of light transmitted through or scattered by such liquid crystal material,and creating a further image in such liquid crystal material for subsequent projection. | 1997 | Semiconductor Photonics and Technology1997，3，3： | 35 |
| 2 | A novel function for the cellulose binding module of cellobiohydrolase I显示文摘A homogeneous cellulose-binding module(CBM)of cellobiohydrolase I(CBHI)from Trichoderma pseudokoningii S-38 was obtained by the limited proteolysis with papain and a series of chromatographs filtration.Analysis of FT-IR spectra demonstrated that the structural changes result from a weakening and splitting of the hydrogen bond network in cellulose by the action of CBMCBHI at 40℃for 24 h.The results of molecular dynamic simulations are consistent with the experimental conclusions, and provide a nanoscopic view of the mechanism that strong and medium H-bonds decreased dramatically when CBM was bound to the cellulose surface.The function of CBMCBHI is not only limited to locating intact CBHI in close proximity with cellulose fibrils,but also is involved in the structural disruption at the fibre surface.The present studies provided considerable evidence for the model of the intramolecular synergy between the catalytic domain and their CBMs. | WANG LuShan 1,2 ,ZHANG YuZhong 1 &GAO PeiJi 1 1State Key Laboratory of Microbial Technology,Shandong University,Jinan 250100,China 2Beijing Laboratory of Nanoscale Physics&Devices,Chinese Academy of Sciences,Beijing 100080,China | 2008 | Science China(Life Sciences)2008，51，7： | 10 |
| 3 | Valence band structure of strained Si/(111)Si_(1-x)Ge_x显示文摘The strained Si techique has been widely adopted in the high-speed and high-performance devices and circuits. Based on the valence band E-k relations of strained Si/(111)Si1-xGex, the valence band and hole effective mass along the [111] and [-110] directions were obtained in this work. In comparison with the relaxed Si, the valence band edge degeneracy was partially lifted, and the significant change was observed band structures along the [111] and [-110] directions, as well as in its corresponding hole effective masses with the increasing Ge fraction. The results obtained can provide valuable references to the investigation concerning the Si-based strained devices enhancement and the conduction channel design related to stress and orientation. | SONG JianJun, ZHANG HeMing, HU HuiYong, DAI XianYing & XUAN RongXi Key Laboratory of Wide Band-Gap Semiconductor Materials and Devices, School of Microelectronics, Xidian University, Xi’an 710071, China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，3： | 9 |
| 4 | Synthesis of nanostructural ZnO using hydrothermal method for dye-sensitized solar cells显示文摘ZnO nanocrystals with different morphologies were successful synthesized by a simple hydrothermal method combined with and without hexadecyl trimethyl ammonium bromide(CTAB).The phases and morphologies of the products were measured using X-ray diffraction(XRD),scanning electron microscopy(SEM),and transmission electron microscopy(TEM),respectively.The results indicated that the ZnO nanocrystals with different morphologies were of hexagonal wurtzite structure.ZnO nanorods were obtained without using CTAB,and then the morphology of ZnO changed to ZnO nanoflower and the density of nanoflower became denser with the increase of CTAB concentration.ZnO nanoflower and ZnO nanorod as photoanode were applied to dye-sensitized solar cells(DSSC),respectively.The nanoflower shows a higher dye loading,so DSSC with the use of the ZnO nanoflower possesses a higher conversion efficiency than ZnO nanorod. | WANG ChunXiao1,2,ZHANG XiaoDan1,WANG DongFeng1,YANG ZhenHua1,2,JI WeiWei1,ZHANG CunShan2 & ZHAO Ying1 1 Institute of Photo-electronic Thin Film Devices and Technology of Nankai University,Key Laboratory of Photo-electronic Information Science and Technology(Nankai University),Ministry of Education,Tianjin 300071,China 2 College of Information Engineering,Hebei University of Technology,Tianjin 300130,China | 2010 | Science China(Technological Sciences)2010，53，4： | 8 |
| 5 | Antibodies against the C-terminal peptide of rabbit oviductin inhibit mouse early embryo development to pass 2-cell stage显示文摘A full-length rabbit oviductin cDNA(1909bp) was cloned. It consists of a 5’-UTR of 52bp, an open reading frame (ORF) of 1374bp and a 3’-UTR of 483bp and has more than 80% homology with that of other mammal oviductins. N-terminal peptide (NTP) (384 residues) and C-terminal peptide (CTP) (73 residues) of deduced protein precursor has about 80% and 50% identity with that of other mammals respectively. Fusion proteins GST-NTP 368(1R-368N)and GST-CTP73 (369F-441A) were expressed and purified. NH2-terminal of CTP sequencing reveals that the purified protein is consistent with the deduced one. In order to study the function of NTP and CTP the mouse anti-NTP and rabbit anti-CTP antisera were prepared. Tissue-specific (skeleton muscle, oviduct, uterus, ovary, liver, heart and brain) analysis indicated that rabbit oviductin was only found in oviduct. The conditioned medium derived from the rabbit oviduct mucosa epithelial cells has a function of overcoming the early embryonic development block of Kunming mous e cultured in vitro. Anti-CTP antiserum could totally inhibit the early embryo development at 2-cell stage cultured in the conditioned culture medium, but anti-NTP antiserum couldn’t. There was a positive relationship between the ratio of early embryos at development block and the dosage of anti-CTP antiserum added in the conditioned culture medium. These results suggest that oviductin has a function not only on fertilization, but also on the release of early embryonic development block, and the later function domain of rabbit oviductin may be situate in its C-terminal. | PAN YONG, ZHENG GU, JIN PING LUO, JUN Ru WANG, JIA KE TSO National Laboratory of Contraceptives and Devices Research, Shanghai Institute of Planned Parenthood Research, 21.40 Xietu Road, Shanghai 200032, China | 2002 | Cell Research2002，12，1： | 8 |
| 6 | A novel ubiquitin carboxyl terminal hydroase is involved in toad oocyte maturation显示文摘p28, a 28kD protein from toad (Bufo bufo gargarizans) oocytes, was identified by using p13suc1-agaroseaffinity chromatography. Sequence homology analysis of the full-length cDNA of p28 (Gene Bank accessionnumber: AF 314091) indicated that it encodes a protein containing 224 amino-acids with about 55% iden-tities and more than 70% positives to human, rat or mouse UCH-L1, and contains homological functionaldomains of UCH family. Anti-p28 monoclonal antibody, on injecting into the oocytes, could inhibit theprogesterone-induced resumption of meiotic division in a dose-dependent manner. The recombinant proteinp28 showed similar SDS/PAGE behaviors to the native one, and promoted ubiquitin ethyl ester hydrolysis,a classical catalytic reaction for ubiquitin carboxyl terminai hydrolases (UCHs). The results in this paperreveal that a novel protein, p28, exists in the toad oocytes, is a UCH L1 homolog, was engaged in theprocess of progesterone-induced oocyte maturation possibly through an involvement in protein turnover anddegradation. | ZHAO GUI SUN1,2,3,*, WEI HUA KONG2,*, YAN JUN ZHANG2, SHAN YAN1, JI NING LU1, ZHENG GU1, FENG LIN1, JIA KE TSO1,**1 National Laboratory of Contraceptives and Devices Research, Shanghai Institute of Planned ParenthoodResearch, Shanghai 200032, China2 Colle | 2002 | Cell Research2002，12，4： | 8 |
| 7 | Eu^(3+)-doped LaPO_4 and LaAlO_3 nanosystems and their luminescence properties显示文摘Eu3+ ion-doped LaPO4 nanowires or nanorods have been successfully synthesized by a simple hydrothermal method.The influence of varying the hydrothermal and subsequent sintering conditions on the morphology and structure of the LaPO4 host has been investigated by scanning electron microscopy(SEM) and X-ray diffraction(XRD).For comparison,the Eu3+ ions were also doped into monoclinic monazite LaPO4 nanoparticles and perovskite LaAlO3 nanoparticles.The relative intensities of the emission lines of the LaPO4:Eu3+ nanosystems were essentially independent of their shape.The optimal doping concentrations in the monoclinic LaPO4 and perovskite LaAlO3 nanosystems were determined to be about 5.0 and 3.5 mol%,respectively.Under appropriate UV-radiation,the red light emitted from LaAlO3:Eu3+(3.5 mol%) was brighter than that from LaPO4:Eu3+(5.0 mol%) nanomaterial,resulting from differences in their spin-orbit couplings and covalence,which indicates that the nanoscale LaAlO3 is a promising host material for rare earth ions. | WAN Qiang,HE YuPing,DAI Ning & ZOU BingSuo State Key Laboratory of State Key Laboratory of Chemo/Biosensing and Chemometrics and Key Laboratory for Micro-Nano Opto-Electronic Devices of Ministry of Education,Hunan University,Changsha 410082,China | 2009 | Science China Chemistry2009，52，8： | 6 |

External quantum efficiency (QE) of the diode fabricated from the copolymer with 15% DBT content reaches 1.4% (ph/el), over 1.0 cd/A in luminance efficiency at the driving voltage of 4.2 V. The highest luminance can reach 3780 cd/m2 at 8.2 V.

| 12 | Fabrication of multi-level branched metal nanowires by AAO template electro-deposition显示文摘Anodic aluminum oxide (AAO) tem- plates with various branched pores were prepared through one- to multi-step varying the anodic voltage by a factor of 1/ 2 during an anodization of alumi- num. The corresponding branched Fe nanowires (i.e. Y-branched, two-level branched and more complex tree-like nanostructures) were achieved by electrodepositing Fe into the branched pores of the AAO template. Selecting area electron diffraction and high-resolution TEM images show that the stem and branches of the branched Fe nanowires are single- crystalline with a face-centered cubic lattice. These branched Fe nanowires will be of great fundamental and practical significance. | XU Liping1,2, YUAN Zhihao1,2 & ZHANG Xiaoguang1,21.

| 13 | Improved electrical properties of the two-dimensional electron gas in AlGaN/GaN heterostructures using high temperature AlN interlayers显示文摘The electrical properties of two-dimensional electron gas (2DEG) in AlGaN/GaN heterostructures using high temperature (HT) AlN interlayers (ITs) grown on c-plane sapphire substrate by metal organic chemical vapor deposition (MOCVD) have been investigated.It is found that the electrical properties (electron mobility and sheet carrier density) are improved compared with those in the conventional AlGaN/GaN heterostructures without HT AlN ITs,and the improved 2DEG properties result in the reduction of the sheet resistance.The results from high resolution X-ray diffraction (HRXRD) and Raman spectroscopy measurements show that HT AlN ITs increase the in-plane compressive strain in the upper GaN layer,which enhances the piezoelectric polarization in it and consequently causes increasing of 2DEG density at the AlGaN/GaN interface.Meanwhile,the compressive strain induced by HT AlN ITs leads to a less tensile strain in AlGaN barrier layer and causes positive and negative effects on the sheet carrier density of 2DEG,which counteract each other.The HT AlN ITs reduce the lattice mismatch between the GaN and AlGaN layers and smooth the interface between them,thus increasing the electric mobility of 2DEG by weakening the alloy-related interface roughness and scattering.In addition,the surface morphology of AlGaN/GaN heterostructures is improved by the insertion of HT AlN ITs.The reason for the improved properties is discussed in this paper. | XUE JunShuai,HAO Yue,ZHANG JinCheng & NI JinYu Key Laboratory of Wide Band-Gap Semiconductors and Devices,School of Microelectronics,Xidian University,Xi’an 710071,China | 2010 | Science China(Technological Sciences)2010，53，6： | 4 |
| 14 | Quantifying the effectiveness of SiO_2/Au light trapping nanoshells for thin film poly-Si solar cells显示文摘In order to enhance light absorption of thin film poly-crystalline silicon(TF poly-Si)solar cells over a broad spectral range, and quantify the effectiveness of nanoshell light trapping structure over the full solar spectrum in theory,the effective photon trapping flux(EPTF)and effective photon trapping efficiency(EPTE)were firstly proposed by considering both the external quantum efficiency of TF poly-Si solar cell and scattering properties of light trapping structures.The EPTF,EPTE and scattering spectrum exhibit different behaviors depending on the geometric size and density of nanoshells that form the light trapping layer.With an optimum size and density of SiO2/Au nanoshell light trapping layer,the EPTE could reach up to 40%due to the enhancement of light trapping over a broad spectral range,especially from 500 to 800 nm. | BAI YiMing 1 ,WANG Jun 2 ,CHEN NuoFu 1,3 ,YAO JianXi 1 ,YIN ZhiGang 3 ,ZHANG Han 3 , ZHANG XingWang 3 ,HUANG TianMao 3 ,WANG YanShuo 3 &YANG XiaoLi 3 1School of Renewable Energy Engineering,North China Electric Power University,Beijing 102206,China 2 National Engineering Research Center for Optoelectronic Devices,Institute of Semiconductors, Chinese Academy of Sciences,PO Box 912,Beijing 100083,China 3 Key Laboratory of Semiconductor Materials Science,Institute of Semiconductors, Chinese Academy of Sciences,PO Box 912,Beijing 100083,China | 2010 | Science China(Technological Sciences)2010，53，8： | 4 |
| 15 | The influence of interface exchange coupling on the demagnetization process for perpendicularly oriented FePt/α-Fe/FePt trilayers显示文摘The influence of the interface exchange coupling on the magnetization reversal process for a FePt/α-Fe/FePt tri-layer structure has been studied through a micromagnetic approach.The analytical formula of the nucleation field has been derived.It is found that the nucleation field increases as the interface coupling constant rises.Especially when the thickness of the soft layer is small,the influence of the exchange coupling on the nucleation field is significant.The angular distributions of the magnetization for various exchange coupling constants have been obtained by numerical calculation.It is found that the angular distribution of the magnetization is discontinuous at the interface of the hard and soft layers.In the meantime,the pinning field decreases with the increase of the thickness of the soft layer and the exchange coupling constant. | BO Niao1,ZHAO GuoPing1,2*,YE LinNing3,XU JinSong1 & DENG Ya1 1 College of Physics and Electronic Engineering,Sichuan Normal University,Chengdu 610068,China 2 State Key Laboratory of Electronic Thin Films and Integrated Devices,University of Electronic Science and Technology of China,Chengdu 610054,China 3 School of Economic Information Engineering,Southwestern University of Finance and Economics,Chengdu 610074,China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，10： | 4 |
| 16 | A fast method to diagnose phase transition from amorphous to microcrystalline silicon显示文摘A series of hydrogenated silicon thin films were prepared by the radio frequency plasma enhanced chemical vapor deposition method (RF-PECVD) with various si-lane concentrations. The influence of silane concentration on structural and elec-trical characteristics of these films was investigated to study the phase transition region from amorphous to microcrystalline phase. At the same time,optical emis-sion spectra (OES) from the plasma during the deposition process were monitored to get information about the plasma properties,Raman spectra were measured to study the structural characteristics of the deposited films. The combinatorial analysis of OES and Raman spectra results demonstrated that the OES can be used as a fast method to diagnose phase transition from amorphous to microcrystalline silicon. At last the physical mechanism,why both OES and Raman can be used to diagnose the phase transition,was analyzed theoretically. | HOU GuoFu1,2,3,XUE JunMing1,2,3,YUAN YuJie1,2,3,SUN Jian1,2,3,ZHAO Ying1,2,3 & GENG XinHua1,2,3 1 Institute of Photoelectronics,Nankai University,Tianjin 300071,China 2 Tianjin Key Laboratory of Photoelectronic Thin Film Devices and Technique,Tianjin 300071,China 3 Key Laboratory of Optoelectronic Information Science and Technology of Ministry of Education of China,Tianjin 300071,China | 2007 | Science China(Physics,Mechanics & Astronomy)2007，50，6： | 4 |
| 17 | A mechanism for enhanced photocatalytic activity of nano-size silver particle modified titanium dioxide thin films显示文摘Ag-TiO2 nanostructured thin films with silver volume fraction of 0–20% were deposited on silicon and quartz substrates by RF magnetron sputtering and annealed in ambient air at 950°C for 1 h. The phase structure and surface topography of the films were characterized by X-ray diffractometer and transmission electron microscope. Photocatalytic activity of the films was evaluated by light induced degradation of methyl orange (C14H14N3NaO3S) solution using a high pressure mercury lamp as lamp-house. The relation of photocatalytic activity and silver content was studied in detail. It was found that silver content influences phase structure of TiO2 thin films, and silver in the films is metallic Ag (Ag0). With increasing silver content from 0 to 20 vol%, photocatalytic activity of the films increases first and then decreases. A suitable amount (2.5–5 vol%) silver addition can significantly enhance the photocatalytic activity of TiO2 films. The enhanced photocatalytic activity was mainly attributed to the extension of visible light absorption region of the films, the presence of anatase phase, the increase of oxy-gen anion radicals O2? and reactive center of surface Ti3+, and the better separation between electrons and holes on the films surface. | MENG FanMing1,2,3*, LU Fei1,3, SUN ZhaoQi1,3 & Lü JianGuo1,2,4 1 School of Physics and Materials Science, Anhui University, Hefei 230039, China 2 Key Laboratory of Materials Modification by Laser, Ion and Electron Beams (Dalian University of Technology), Ministry of Education, Dalian 116024, China 3 Anhui Key Laboratory of Information Materials and Devices, Anhui University, Hefei 230039, China 4 Department of Physics and Electronic Engineering, Hefei Normal University, Hefei 230061, China | 2010 | Science China(Technological Sciences)2010，53，11： | 4 |

| 19 | Influence of CaZrO_3 on dielectric properties and microstructures of BaTiO_3-based X8R ceramics显示文摘The influences of CaZrO3 on the dielectric properties and microstructures of BaTiO3 (BT)-based ceramics have been investigated. The experiment results showed that the dielectric constant at room temperature increased with the addition of CaZrO3 in the range of 0―3.0 mol%, which could be explained by the growth of BT grains. XRD analysis revealed that the tetragonality declined as CaZrO3 concentration in-creased. XRD patterns of BT ceramics with different amounts of CaZrO3 doping were analyzed by a recently developed procedure-materials analysis using diffrac-tion (MAUD), which was based on the Rietveld method combined with Fourier analysis. The results depicted that the high temperature peak of tempera-ture-capacitance characteristics (TCC) was largely dependent on the micro-strain of samples. Furthermore, more CaZrO3 doping resulted in lower porosity and higher density. It was revealed that proper usage of CaZrO3 could improve the di-electric properties significantly, which was benefit to develop X8R multi-layer ce-ramic capacitors. | TANG Bin, ZHANG ShuRen, YUAN Ying, ZHOU XiaoHua & LIANG YiShuai State Key Laboratory of Electronic Thin Films and Integrated Devices, University of Electronic Science and Technology of China, Chengdu 610054, China | 2008 | Science China(Technological Sciences)2008，51，9： | 2 |
| 20 | Simulation study of phase retrieval for hard X-ray in-line phase contrast imaging显示文摘Two algorithms for the phase retrieval of hard X-ray in-line phase contrast imaging are presented. One is referred to as Iterative Angular Spectrum Algorithm (IASA) and the other is a hybrid algorithm that combines IASA with TIE (transport of intensity equation). The calculations of the algorithms are based on free space propagation of the angular spectrum. The new approaches are demonstrated with numerical simulations. Comparisons with other phase retrieval algorithms are also performed. It is shown that the phase retrieval method combining the IASA and TIE is a promising technique for the application of hard X-ray phase contrast imaging. | YU Bin1,2, PENG Xiang1,2, TIAN Jindong1, NIU Hanben1, DIAO Luhong3 & LI Hua3 1.
