| 1 | A new insight into cattle's maternal origin in six Asian countries显示文摘The domestication of cattle fuelled the development of agricultural society in the history of human being.The evolution and genetic relationship of cattle can be elucidated by investigating the variation of mitochondrial DNA(mtDNA) D-loop sequence.In this study,we built a cattle phylogeny with a pool of 856 individual D-loop sequences,of which 264 Chinese cattle D-loop sequences were obtained in this study(141 ones were first analyzed,and 123 were first submitted) and the rest sequences of cattle from six Asian countries(Japan,Korea,Mongolia,Nepal,India and China) were retrieved from GenBank.Our results indicated that cattle from six Asian countries fell into three clades,Bos taurus(taurine),Bos indicus(zebu) and yak.Four main haplogroups T1A,T2,T3(including T3A and T3B) and T5 were found in taurine,and two haplogroups I1 and I2 in zebu.Furthermore,we found that I1 and I2 haplogroups were separated by four variable sites rather than five ones and four haplogroups or sub-haplogroups of T1A,T3A,T3B and T5 were found for the first time in these Asian cattle.These data brought us a new insight into cattle's genetic structure in these six Asian countries.The geographical distribution of haplogroups was also outlined to provide systematic information on cattle genetic resources. | Shangang Jia Yan Zhou Chuzhao Lei Ru Yao Zhiying Zhang Xingtang Fang Hong Chen | 2010 | Journal of Genetics and Genomics2010，37，3： | 8 |
| 2 | Investigation of tribological properties of composite C_(60)-LB films显示文摘Composite C60-LB films were fabricated by the Langmuir-Blodgett (LB) technique, their micro- structures, micro- and macro-tribological properties were investigated using atomic force microscope/ friction force microscope (AFM/FFM). The results showed that in the confined C60-LB films there were two kinds of structures for the special C60 assembly: grain diameters of one kind were in the range of 150 -230 nm; the other was smaller than 20 nm. Mi- cro-tribological studies showed that topographical images of tiny C60 aggregates (<20 nm) were con- sistent with their frictional ones very well, namely, low friction occurred on tiny C60 aggregates compared with fatty chains LB monolayer, and ‘Micro-rolling effect’ was apparent; but for big large ones frictional forces were relatively high and ‘ratchet mechanism’ was seen apparently. Macro-tribological data proved large C60 aggregates had wear resistance and load-carrying capacities and anti-wear lives for com- posite C60-LB films were prolonged greatly with dis- persibility of C60 improved and its grain diameter re- duced. Tiny C60 aggregates were mainly the lubri- cating agents. Friction coefficients of composite C60-LB films gradually reduced with loads increasing having the same friction coefficient-load relations with boundary lubrication films. | YANG Guanghong ZHANG Xingtang XUN Jun JIANG Xiaohong ZHANG Pingyu DU Zuliang | 2006 | Chinese Science Bulletin2006，51，15： | 3 |
| 3 | Chemical modification and the photoluminescence stabilization of titanic acid nanotubes显示文摘Titanic acid nanotubes (H2Ti2O4(OH)2) were surface-modified with cetyl alcohol through dehydration reaction because of existence of Ti–OH. The modified nanotubes were characterized by transmission electron microscopy (TEM), Fourier Transform Infrared (FT-IR) spectrometry and pho-toluminescence (PL) spectra. The results indicate that the modified nanotubes can be easily dis-persed into organic solvent such as chloroform and toluene in contrast with the unmodified nanotubes, which makes it easier to be assembled by LB technique. Moreover, the Ti-O-CH2(CH2)14CH3 on the surface of the nanotubes can hinder the adsorption of water and consequently the photoluminescence property of the nanotubes can be stabilized. Even though kept in humid condition or in air for a long time, the modified nanotubes also maintain the special photoluminescence property in the visible re-gion. | ZHANG Xingtang WANG Yumei ZHANG Chunmei JIANG Xiaohong TIAN Baoli LI Yuncai HUANG Yabin DU Zuliang | 2006 | Science China Chemistry2006，49，2： | 2 |
| 4 | Solvothermal synthesis of CdS nanorods and photovoltaic characteristics of CdS/PVK composite system显示文摘Large quantities of CdS nanorods are successfully synthesized through Cd(CH3COO)2·2H2O reacting with Na2S·9H2O and EDA in aqueous solution. XRD result shows that the sample is of hexagonal structure. And TEM result shows that the morphologies of the resulting CdS are mainly in three-armed rod-like structure with a diameter of 10―15 nm and a length of 100 nm. The nanocomposites of CdS/PVK with different molar ratios are prepared by spin coating method on tin-doped indium oxide (ITO) substrate. A notable decrease of photoluminescence (PL) efficiency and a significant enhance-ment of surface photovoltage signal have been observed in CdS/PVK composites when the molar frac-tion of CdS increases. We interpret these results as the energy level matching between CdS and PVK in nanocomposites. This energy level matching facilitates fast interfacial charge transfer then increases the separation efficiency of electron-hole pairs and the carrier generation efficiency. The detailed charge transfer process has also been demonstrated. | JI YanLing CHENG Ke ZHANG HongMei ZHANG XingTang LI YunCai DU ZuLiang | 2008 | Chinese Science Bulletin2008，53，1： | 2 |
| 5 | Fabrication of metal oxide nanostructures based on Atomic Force Microscopy lithography显示文摘Atomic Force Microscopy (AFM) mechanical lithography is a simple but significant method for nanofabrication. In this work, we used this method to construct nanos- tructures on Pt/Cu bilayer metal electrodes under ambient conditions in air. The influence of various scratch parameters, such as the applied force, scan velocity and circle times, on the lithography patterns was investigated. The Pt-Cu-CuxO-Cu-Pt nanostructure was constructed by choosing suitable scratch parameters and oxidation at room temperature. The properties of the scratched regions were also investigated by friction force microscopy and conductive AFM (C-AFM). The I-V curves show symmetric and linear properties, and Ohmic contacts were formed. These results indicate that AFM mechanical lithography is a powerful tool for fabricating novel metal-semiconductor nanoelectronic devices. | ZHU XiaoYang CHENG Gang WANG ShuJie DAI ShuXi WAN ShaoMing ZHANG XingTang DU ZuLiang | 2008 | Science China(Physics,Mechanics & Astronomy)2008，51，10： | 1 |

| 7 | Fabrication of gold nanoelectrodes based on nanolithography electrochemically through a conductive AFM tip显示文摘Gold nanoelectrodes were fabricated by ap- proach of combining surface self-assembly with nanolitho- graphy electrochemically through a conductive AFM tip. The controllable structure with width and distance in nanometer as a template was constructed by nanolithography patterning process, which was accomplished by a conductive AFM tip on certain highly ordered long-tail organosilane monolayers. Then through adsorption of Cd2+ and exposure of the Cd2+-loaded surface to gaseous H2S, CdS nanowires were generated in a template-controlled self-assembly process. Finally, metallic gold nanowires were conversed from CdS nanowires by treatment with the aqueous solution of HAuCl4 via a redox chemical process, which had good conductivity proved by C-AFM. | LI Tianfeng ZHANG Xingtang JIANG Xiaohong LI Yuncai DU Zuliang | 2005 | Chinese Science Bulletin2005，50，22： | 1 |
| 8 | A hyperspectral image compression algorithm based on wavelet transformation and fractal composition (AWFC)显示文摘Starting with a fractal-based image-compression algorithm based on wavelet transformation for hyperspectral images, the authors were able to obtain more spectral bands with the help of of hyperspectral remote sensing. Because large amounts of data and limited bandwidth complicate the storage and transmission of data measured by TB-level bits, it is important to compress image data acquired by hyperspectral sensors such as MODIS, PHI, and OMIS; otherwise, conventional lossless compression algorithms cannot reach adequate compression ratios. Other loss-compression methods can reach high compression ratios but lack good image fidelity, especially for hyperspectral image data. Among the third generation of image compression algorithms, fractal image compression based on wavelet transformation is superior to traditional compression methods,because it has high compression ratios and good image fidelity, and requires less computing time. To keep the spectral dimension invariable, the authors compared the results of two compression algorithms based on the storage-file structures of BSQ and of BIP, and improved the HV and Quadtree partitioning and domain-range matching algorithms in order to accelerate their encode/decode efficiency. The authors' Hyperspectral Image Process and Analysis System (HIPAS) software used a VC++6.0 integrated development environment (IDE), with which good experimental results were obtained. Possible modifications of the algorithm and limitations of the method are also discussed. | HU Xingtang ZHANG Bing ZHANG Xia ZHENG Lanfen TONG Qingxi | 2006 | Science China(Technological Sciences)2006，49，z2： | 1 |

| 12 | Preparation of sodium titanate nanotubes modified by CdSe quantum dots and their photovoltaic characteristics显示文摘Sodium titanate nanotubes have been prepared and modified chemically with CdSe quantum dots (QDs) using bifunctional modifiers (HS-COOH). Their photovoltaic characteristics have also been studied. The results indicate that the surface photovoltage response of nanotubes extends to the visible light region, and the intensity of surface photovoltage is enhanced after modification with CdSe QDs. The field-induced surface photovoltage spectroscopy (FISPS) shows that sodium titanate nanotubes have different photovoltaic response before and after modification. That is, the surface photovoltaic re-sponse of pure sodium titanate nanotubes increases with the enhancement of positive applied bias and decreases with the enhancement of negative applied bias. Meanwhile, the surface photovoltaic re-sponse of CdSe modified sodium titanate nanotubes is different from that of the pure sodium titanate nanotubes. The whole spectrum increases with the enhancement of applied bias at the first stage. However, when the applied bias reaches a certain value, the surface photovoltage response keeps in-creasing in some spectrum regions, while decreasing in other spectrum regions. This novel phe-nomenon is explained by using an electric field induced dipole model. | ZHANG HongMei CHENG Ke JI YanLing LIU XiaoLan LI LinSong ZHANG XingTang DU ZuLiang | 2008 | Science China Chemistry2008，51，10： | 0 |
| 13 | Fabrication and green emission of ZnO nanowire arrays显示文摘Well-aligned single-crystalline wurzite zinc oxide (ZnO) nanowire arrays were successfully fabricated on a Si substrate by a simple physical vapor-deposition (PVD) method at a relatively low temperature of about 500℃. The as-fabricated nanowires were preferentially arranged along the [001] direction of ZnO. The photoluminescence spectrum of ZnO nanowire arrays showed two emission bands: a strong green emission at around 500 nm and a weak ultraviolet emission at 380 nm. The strong green light emission was related to the existence of the oxygen vacancies in ZnO crystals. Corresponding growth mecha- nism of the ZnO nanowires was briefly discussed. | Bin Zhang ShaoMin Zhou Bing Liu HeChun Gong XingTang Zhang | 2009 | Science China(Technological Sciences)2009，52，4： | 0 |
