| 1 | Approaches to prediction of impact of Qinghai-Tibet Railway construction on alpine ecosystems alongside and its recovery显示文摘With the aid of the Remote Sensing (RS) and Geographic Information System (GIS) technology, the eco-system pattern and fragility distribution maps of the 50-km-wide zone along the Qinghai-Tibet Railway were com-piled and by using the superimposition method, range, area and indexes of the impact of various engineering activities on the ecosystems alongside the railway were studied. By making reference to the ecosystem recovery process of the Qinghai-Tibet Highway, mechanisms of recovery of the al-pine ecosystems alongside the Qinghai-Tibet Railway were studied and extents and rates of the recovery were predicted. The results indicate that the impact of the railway engineer-ing on the Alpine ecosystem depends mainly on how much the original surface soil in the zone has been disturbed and how fragile of the ecosystem per se. Restoration of vegetation coverage and species abundance shows a significantly reverse relationship with disturbance of the original surface soil but an extremely positive one with the length of the restoration period and mean annual precipitation and annual mean rela-tive humidity in the period and no obvious bearings with altitude and temperature. In sections with an annual pre-cipitation over 200 mm, as long as a certain percentage of original soil is left in situ, it takes only 30 years or so for bio-diversity to get basically restored to the original level after the construction is completed but at least 45—60 years or more for vegetation coverage. | SHENWeishou ZHANGHui ZOUChangxin CAOXuezhang TANGXiaoyan | 2004 | Chinese Science Bulletin2004，49，8： | 9 |
| 2 | Low frequency vibration control of railway vehicles based on ahigh static low dynamic stiffness dynamic vibration absorber显示文摘In order to control the low frequency vibration of railway vehicles, a vertical two degrees of freedom(2DOF) low frequency dynamic vibration absorber(DVA) based on acceleration is proposed. Parameters of the dynamic vibration absorber are put forth to control the low frequency vibration of car body bouncing and pitching. Next, the acceleration power spectrum density(PSD)and ride quality of the car body are calculated based on the pseudo excitation method(PEM) and covariance algorithm,respectively. According to the requirement of 2DOF low frequency DVA, the isolators with high static low dynamic stiffness(HSLDS) are designed. A high-speed train dynamic model containing HSLDS isolators is established to validate the effects on the car body vibration. The results reveal that the 2D low frequency DVA can significantly reduce the vibration of the car body bouncing and pitching. Thus, the ride quality of the vehicle is increased, and passenger comfort is improved. | SUN Yu GONG Dao ZHOU JinSong SUN WenJing XIA ZhangHui | 2019 | Science China(Technological Sciences)2019，62，1： | 6 |
| 3 | Novel layered pesticide slow/controlled release materials——supramolecular structure and slow release property of glyphosate intercalated layered double hydroxides显示文摘Two different interlayer structured glyphosate (GLY) intercalated MgAl layered double hydroxides, as novel pesticide slow/controlled release materials, have been synthesized by co-precipitation method under various reac- tion pH values. The slow/controlled release properties have been tested in Na2CO3 aqueous solution. The release mecha- nism has been interpreted on the basis of the ion-exchange between the guest GLY anions in the lamellar host and 23CO ? in the release media, and the diffusion process of GLY anions in the interstice and interlayer of GLY intercalates, i.e diffusion through the particles, is the rate-limiting step of GLY release process. The GLY intercalate assembled at lower pH, possessing higher interlayer gallery height and vertical monolayered arrangement of guest anions in the interlayer with larger packing density, exhibits better slow release property than that assembled at higher pH. The re- sults reveal that the layered double hydroxides have potential application in the pesticide slow/controlled release area. | MENGJinhong ZHANGHui DavidG.Evans DUANXue | 2005 | Chinese Science Bulletin2005，50，8： | 5 |
| 4 | The specific carbon isotopic compositions of branched and cyclic hydrocarbons from Fushun oil shale显示文摘Various branched and cyclic hydrocarbons are isolated from the Fushun oil shale and their carbon isotopes are determined. The analytical results show that the branched and cyclic hydrocarbons are fully separated from n-alkanes by 5 molecular-sieve adduction using long time and cold solvent. The branched and cyclic hydrocarbon frac-tion obtained by this method is able to satisfy the analytic requests of GC-IRMS. The carbon isotopic compositions of these branched and cyclic hydrocarbons obtained from the sample indicate that they are derived from photoautotrophic algae, chemoautotrophic bacteria (-33.4—-39.0) and methanotrophic bacteria (-38.4—-46.3). However the long-chain 2-methyl-branched alkanes indicate that their carbon isotopic compositions reflect biological origin from higher plants. The carbon isotopic composition of C30 4-methyl sterane (-22.1? is the heaviest in all studied ste- ranes, showing that the carbon source or growth condition for its precursor, dinoflagellate, may be different from that of regular steranes. The variation trend of d 13C values between isomers of hopanes shows that 13C-enriched precursors take precedence in process of their epimerization. Methanotro-phic hopanes presented reveal the processes of strong trans-formation of organic matter and cycling of organic carbon in the water column and early diagenesis of oil shale. | DUANYi WUBaoxiang ZHENGGuodong ZHANGHui ZHENGChaoyang | 2004 | Chinese Science Bulletin2004，49，4： | 3 |
| 5 | InP quantum dots on g-C_(3)N_(4) nanosheets to promote molecular oxygen activation under visible light显示文摘Largely limited by the high dissociation energy of the O—O bond,the photocatalytic molecular oxygen activation is highly challenged,which re strains the application of photocatalytic oxidation technology for atmospheric pollutants removal.Herein,we design and fabricate the InP QDs/g-C_(3)N_(4) compounds.The introduction of InP QDs promotes the charge transfer within the interface resulting in the effective separation of photo-generated carriers.Furthermore,InP QDs greatly facilitates the activation of molecular oxygen and promote the formation of O_(2)·under visible-light illuminatio n.These conclusions are identified by experimental and calculation results.Hence,NO can be combined with the O_(2)·to form O—O—N—O intermediate to direct conversion into NO_(3).As a result,the NO removal ratio of g-C_(3)N_(4) has a one fold increase after InP QDs loaded and the generation of NO_(2) is effectively inhibited.This wo rk may provide a strategy to design highly efficient materials for molecular oxygen activation. | Yuehan Cao Qian Zheng Zhiqiang Rao Ruiyang Zhang Zhanghui Xie Shan Yu Ying Zhou | 2020 | Chinese Chemical Letters2020，31，10： | 3 |
| 6 | Effects of reduction temperature and content of Pd loading on the performance Pd/CeO2 catalyst for CO oxidation显示文摘The content of noble metal loading and the reduction process of the catalysts are important factors influence the economic indicator and catalytic performance for industrial catalysis. In the present work, Pd/CeO2NT (Pd supported on the CeO2 nanotubes) catalysts are prepared with the hydrothermal synthesized CeO2NT and glutathione (GSH) reduced Pd nanoparticles via impregnation. The content of Pd loading as well as the catalysts reduction temperature are optimized to the CO oxidation reduction. Our results show that the best Pd loading is 1.5%Pd/CeO2NT. The catalysts reduced at 350 ℃ for 2 h prior to catalytic reaction perform the best toward CO oxidation, which reaches completely CO conversion at 70 ℃. The XRD, Raman, H2-TPR, TEM, BET and XPS characterization reveal that the excellent catalytic performance of 350 °C 1.5%Pd/CeO2NT sample can be attributed the high Pd^0 species and oxygen vacancy in the sample, which are important factors influence the activity of the catalysts. | Yue Yan Huaxi Li Zhanghui Lu Xuewen Wang Rongbin Zhang Gang Feng | 2019 | Chinese Chemical Letters2019，30，6： | 2 |
| 7 | Synthesis and characterization of nanoscale magnetic drug-inorganic composites显示文摘The synthesis by direct coprecipitation and characterization of captopril (Cpl) and 5-aminosalicylic acid (5-ASA) intercalated ZnAl layered double hydroxides coated on MgFe2O4 magnetic core particles are reported. Powder XRD analysis shows the well-defined crystallite structure of the composites. TEM and XPS results reveal that a core-shell structure involving a drug-LDHs layer coated on MgFe2O4 particles is formed through Zn-O-Mg and/or Al-O-Mg link- ages. VSM measurements demonstrate that the novel mag- netic drug-inorganic composites possess considerable mag- netization. | SUNHui ZHANGHui DavidG.Evans DUANXue | 2005 | Chinese Science Bulletin2005，50，8： | 2 |
| 8 | Topological Aspect and Bifurcation of Disclination Lines in Two—Dimensional Liquid Crystals显示文摘Using φ-mapping method and topological current theory, the topological structure and bifurcation ofdisclination lines in two-dimensional liquid crystals are studied. By introducing the strength density and the topologicalcurrent of many disclination lines, the total disclination strength is topologically quantized by the Hopf indices andBrouwer degrees at the singularities of the director field when the Jacobian determinant of director field does not vanish.When the Jacobian determinant vanishes, the origin, annihilation and bifurcation processes of disclination lines arestudied in the neighborhoods of the limit points and bifurcation points, respectively. The branch solutions at the limitpoint and the different directions of all branch curves at the bifurcation point are calculated with the conservation lawof the topological quantum numbers. It is pointed out that a disclination line with a higher strength is unstable and itwill evolve to the lower strength state through the bifurcation process. | YANGGuo-Hong ZHANGHui 等 | 2002 | Communications in Theoretical Physics2002，37，5： | 2 |
| 9 | Wavelength-sensitive photocatalytic H2 evolution from H2S splitting over g-C3N4 with S,N-codoped carbon dots as the photosensitizer显示文摘Photocatalytic splitting of hydrogen sulfide(H2S) for hydrogen evolution is a promising method to solve the energy and environmental issues.In this work,S,N-codoped carbon dots(S,N-CDs)/graphitic carbon nitride(g-C3N4) nanosheet is synthesized by hydrothermal method as an efficient photocatalyst for the decomposition of H2S.In addition to the characterization of the morphology and structure,chemical state,optical and electrochemical performances of S,N-CDs/g-C3N4,hydrogen evolution tests show that the activity of g-C3N4 is improved by introducing S,N-CDs,and the enhancement depends strongly on the wavelength of incident light.The photocatalytic hydrogen production rate of S,N-CDs/g-C3N4 composite reaches 832 μmol g-1h-1, which is 38 times to that of g-C3N4 under irradiation at 460 nm.Density functional theory calculations and electron paramagnetic resonance as well as photoluminescence technologies have altogether authenticated that the unique wavelength-dependent photosensitization of S,N-CDs on g-C3N4;meanwhile,a good match between the energy level of S,N-CDs and g-C3N4 is pivotal for the effective photocatalytic activity.Our work has unveiled the detailed mechanism of the photocatalytic activity enhancement in S,N-CDs/g-C3N4 composite and showed its potential in photocatalytic splitting of H2S for hydrogen evolution. | Zhanghui Xie Shan Yu Xiang-Bing Fan Shiqian Wei Limei Yu Yunqian Zhong Xue-Wang Gao Fan Wu Ying Zhou | 2021 | Journal of Energy Chemistry2021，30，1： | 2 |
| 10 | Molecular Cloning and Identification of a Heat Shock Cognate Protein 70 Gene, Thhsc70, in Thellungiella halophila显示文摘Heat shock cognate proteins 70 (hsp70s) act as molecular chaperones. Some hsp70s are also expressed in unstressed plants, known as hsc70. To gain further knowledge about the hsc70, the Thellungiella halophila hsc70 (Thhsc70) gene that encoded the cytosolic hsc70 in salt cress (T.halophila (C.A.Mey.) O.E.Schulz) was identified. In unstressed plants the expression of Thhsc70was shown to be tissue-specific. The Thhsc70 gene was induced by heat and cold stresses, but almost not by salt and drought stresses. Overexpression of Thhsc7Ocould increase thermctolerance and chilling tolerance in transgenic Arabidopsis plants. | ZHANGXia GUOShan-Li YINHai-Bo XIONGDong-Jin ZHANGHui ZHAOYan-Xiu | 2004 | Acta Botanica Sinica2004，46，10： | 2 |
