| 2 | Diffusion tensor imaging detects Wallerian degeneration of the corticospinal tract early after cerebral infarction显示文摘To investigate the feasibility and time window of early detection of Wallerian degeneration in the corticospinal tract after middle cerebral artery infarction,23 patients were assessed using magnetic resonance diffusion tensor imaging at 3.0T within 14 days after the infarction.The fractional anisotropy values of the affected corticospinal tract began to decrease at 3 days after onset and decreased in all cases at 7 days.The diffusion coefficient remained unchanged.Experimental findings indicate that diffusion tensor imaging can detect the changes associated with Wallerian degeneration of the corticospinal tract as early as 3 days after cerebral infarction. | Ruiman Xie Min Fang Linjiang Zhou Shanghua Fan Jianying Liu Hongbo Quan Man Luo Dongying Qiu | 2012 | Neural Regeneration Research2012，7，12： | 20 |
| 3 | Structure and photocatalytic properties of TiO_2-Graphene Oxide intercalated composite显示文摘TiO2-Graphene Oxide intercalated composite (TiO2-Graphene Oxide) has been successfully prepared at low temperature (80°C) with graphite oxide (GO) and titanium sulfate (Ti(SO4)2) as initial reactants.GO was firstly exfoliated by NaOH and formed single and multi-layered graphite oxide mixture which can be defined as graphene oxide,[TiO]2+ induced by the hydrolysis of Ti(SO4)2 diffused into graphene oxide interlayer by electrostatic attraction.The nucleation and growth of TiO2 crystallites took place at low temperature and TiO2-Graphene Oxide composite was successfully synthesized.Furthermore,the photocatalytic properties of TiO2-Graphene Oxide under the irradiation of UV light were also studied.The results show that the degradation rate of methyl orange is 1.16 mg min-1 g-1(refer to the efficiency of the initial 15 min).Compared with P25 powder,this kind of intercalation composite owns much better efficiency.On the other hand,the reusable properties and stable properties of TiO2-Graphene Oxide intercalated composite are also discussed in this paper.At last,crystalline structure,interface status,thermal properties and microscopic structure of TiO2-Graphene Oxide were characterized by X-ray diffraction (XRD),X-ray photoelectron spectroscopy (XPS),thermogravimetric analysis (TGA),field emission scanning electron microscopy (FESEM) and high-resolution Transmission Electron Microscopy (HRTEM).Also,we have analyzed major influencing factors and mechanism of the composite structures which evidently improve the photocatalytic properties. | ZHANG Qiong HE YunQiu CHEN XiaoGang HU DongHu LI LinJiang YIN Ting JI LingLi | 2011 | Chinese Science Bulletin2011，56，3： | 14 |
| 4 | Texture control by {10-12} twinning to improve the formability of Mg alloys: A review显示文摘Texture control of wrought Mg alloys, particularly in rolled Mg alloy sheets, has been an important research topic for the past several decades because it has significant influence on stretch formability at room temperature. For Mg alloys, {10-12} twinning can be easily activated and causes a 86.3° lattice rotation. Thus, pre-twinning deformation is considered as an effective and low-cost method for texture control in wrought Mg and its alloys. Furthermore, it has been verified that texture control via pre-twinning deformation can remarkably improve stretch formability of rolled Mg alloy sheets. In this review, recent researches on texture control via twinning deformation and its influence on stretch formability will be critically reviewed. The main contents include the micro-mechanism and impact factors of control in twin-orientation, plastic processing techniques of pre-inducing twins and the application of pre-induced twins in improvement of stretch formability. Finally, further research directions on this field were proposed. | Bo Song Qingshan Yang Tao Zhou Linjiang Chai Ning Guo Tingting Liu Shengfeng Guo Renlong Xin | 2019 | Journal of Materials Science & Technology2019，35，10： | 8 |
| 5 | Electron backscatter diffraction investigation of duplex-phase microstructure in a forged Zr-2.5Nb alloy显示文摘Microstructural features of a duplex-phase Zr-2.5Nb alloy were investigated in detail using electron channeling contrast(ECC)imaging and electron backscatter diffraction(EBSD)technique in an emission gun scanning electron microscope(FEGSEM).The excellent resolution provided by the FEGSEM promises the combined utilization of both techniques to be quite adequate for characterizing the duplex-phase microstructures.Results show that the microstructure of the Zr-2.5Nb alloy is composed of bulkαgrains(majority)in equiaxed or plate shape and thinβfilms(minority)surrounding the bulk grains,with their average grain size and thickness measured to be 1.4μm and 72 nm,respectively.Analyses onα-grain boundaries reveal a number of low angle boundaries,most of which belong to deformation-induced dislocation boundaries.Measurements on relative proportions of various Burgers boundaries suggest very weak(if any)variant selection duringβ→αcooling,which should be related to deformation-induced higher nucleation rate ofαphases.Compared to earlier attempts,more satisfactory indexing of fineβphases(down to nanoscale)is attained by the FEGSEM-based EBSD.Examples are presented to clearly reveal well-obeyed Burgers orientation relationships between adjacentαandβphases.Finally,it is deduced that continuing application of the FEGSEM-based EBSD to duplex-phase Zr alloys could help clarify controversies like the deformation priority of the two phases. | CHAI LinJiang WANG ShuYan LUAN BaiFeng LIU Qing | 2016 | Science China(Technological Sciences)2016，59，4： | 5 |
| 6 | Effect of cooling rate on β→α transformation during quenching of a Zr-0.85Sn-0.4Nb-0.4Fe-0.1Cr-0.05Cu alloy显示文摘The effect of β→α cooling rate during quenching on a new Zr-Sn-Nb-Fe-Cr-Cu alloy is reported.The microstructure evolution is well characterized by electron channeling contrast(ECC) imaging and transmission electron microscopy(TEM) techniques.The results show that specimens cooled by water,liquid nitrogen,air and furnace from β-phase present martensitic,coarse basket-weave,parallel-plate and lenticular structure,respectively.Residual β phase is detected by performing electron diffraction and composition analysis in the furnace cooled specimen.Micro hardness values of specimens decrease while the width of α laths increase with the cooling rate decreasing.The preliminarily established quantitative relationship among the cooling rate,microstructure and mechanical properties will shed light on the microstructure control and property optimization. | CHAI LinJiang LUAN BaiFeng CHEN JianWei ZHOU Jun LIU Qing | 2012 | Science China(Technological Sciences)2012，55，10： | 5 |
| 7 | α→β Transformation characteristics revealed by pulsed laser-induced non-equilibrium microstructures in duplex-phase Zr alloy显示文摘Microstructures of a duplex-phase Zr-2.5Nb alloy treated by pulsed laser were characterized by electron backscatter diffraction(EBSD) and electron channeling contrast(ECC) imaging techniques.Major attention has been paid to non-equilibrium hybrid microstructure consisting of both prior a and β phases,and a plates transformed from new β phases to probe α→β transformation characteristics in the alloy.The origin of the hybrid microstructure is attributed to the specific thermodynamic conditions induced by the pulsed laser treatment.ECC observation shows that newly formed β phases during laser heating prefer to nucleate and grow at the expense of edges of prior a grains rather than their interiors.EBSD analyses further reveal that orientations of the new βphases are not determined by the prior a grains according to the Burgers relationship but maintain those of the prior β phases in an epitaxial growth way. | CHAI LinJiang WANG Shu Yan WU Hao GUO Ning PAN HuCheng CHEN Liang Yu MURTY K.L.

| 8 | Evolution of surface microstructure of Cu-50Cr alloy treated by high current pulsed electron beam显示文摘A Cu-50Cr alloy was treated by the high current pulsed electron beam(HCPEB)at 20 and 30 ke V with pulse numbers ranging from 1 to 100.Surface morphologies and microstructures of specimens before and after the treatments were investigated by employing scanning electron microscopy and X-ray diffraction.Results show that the HCPEB technique is able to induce remarkable surface modifications for the Cu-50Cr alloy.Cracks in Cr phases appear even after one-pulse treatment and their density always increases with the pulse number.Formation reason for these cracks is attributed to quasi-static thermal stresses accumulated along the specimen surface.Craters with typical morphologies are formed due to the dynamic thermal field induced by the HCPEB and they are found to prefer the sites near cracks or boundaries between neighboring Cr phases.Another microstructural characteristic produced by the HCPEB is the fine Cr spheroids,which are determined to be due to occurrence of liquid phase separation in the Cu-50Cr alloy.Finally,a general microstructural evolution profile that incorporates various HCPEB-induced surface features is tentatively outlined. | CHAI LinJiang ZHOU ZhiMing XIAO ZhiPei TU Jian WANG YaPing HUANG WeiJiu | 2015 | Science China(Technological Sciences)2015，58，3： | 5 |
| 9 | A DFT study on PtMo resistance to SO_2 poisoning显示文摘Pt is a catalyst in proton exchange membrane fuel cell (PEMFC), and its activity will be degraded in the air due to the existence of SOx impurities. On strategy is introducing of Mo into the Pt catalyst because it can improve the SOx -tolerance capacity. Based on the aforementioned phenomenon, a density function theory (DFT) study on SO x adsorbed on Pt(111) and PtMo(111) was performed to enhance Pt catalytic activity. The adsorption energy of adsorbed species, the net change, partial density of state (PDOS), and d-band center were calculated and analyzed comparatively. The results show that the presence of Mo-atom weakens the S-Pt bond strength and reduces the adsorption energies for SO2 , S and SO3 on PtMo(111). Moreover, the Mo atom weakens the effects of SO2 on the PtMo(111) electronic structure and makes the catalyst maintains its original electronic structure after SO2 adsorption as compared with Pt(111). | XIA MeiRong LIU Ying LI Li XIONG Kun QI XueQiang YANG LinJiang HU BaoShan XUE Yun WEI ZiDong | 2013 | Science China Chemistry2013，56，7： | 4 |
| 10 | Inverse identification of constitutive parameters of Ti_2AlNb intermetallic alloys based on cooperative particle swarm optimization显示文摘Ti_2AlNb intermetallic alloy is a relatively newly developed high-temperature-resistant structural material, which is expected to replace nickel-based super alloys for thermally and mechanically stressed components in aeronautic and automotive engines due to its excellent mechanical properties and high strength retention at elevated temperature. The aim of this work is to present a fast and reliable methodology of inverse identification of constitutive model parameters directly from cutting experiments. FE-machining simulations implemented with a modified Johnson-Cook(TANH) constitutive model are performed to establish the robust link between observables and constitutive parameters. A series of orthogonal cutting experiments with varied cutting parameters is carried out to allow an exact comparison to the 2 D FE-simulations. A cooperative particle swarm optimization algorithm is developed and implemented into the Matlab programs to identify the enormous constitutive parameters. Results show that the simulation observables(i.e., cutting forces, chip morphologies, cutting temperature) implemented with the identified optimal material constants have high consistency with those obtained from experiments,which illustrates that the FE-machining models using the identified parameters obtained from the proposed methodology could be predicted in a close agreement to the experiments. Considering the wide range of the applied unknown parameters number, the proposed inverse methodology of identifying constitutive equations shows excellent prospect, and it can be used for other newly developed metal materials. | Linjiang HE Honghua SU Jiuhua XU Liang ZHANG | 2018 | Chinese Journal of Aeronautics2018，31，8： | 4 |

| 12 | Deformation mode-determined misorientation and microstructural characteristics in rolled pure Zr sheet显示文摘In this work, commercially pure Zr sheets were subjected to β air cooling and then rolled to different reductions(10% and 50%)at room temperature. Microstructures of both the β-air-cooled and the rolled specimens were well characterized by electron channelling contrast imaging and electron backscatter diffraction techniques, with special attentions paid to their misorientation characteristics. Results show that the β-air-cooled specimen owns a Widmanst?tten structure featured by lamellar grains with typical phase transformation misorientations. The 10% rolling allows prismatic slip and tensile twinning({11-21}<11-2-6> and{10-12}<10-11>) to be activated profusely, which produce new low-angle(~3°–5°) and high-angle(~35° and ~85°) misorientation peaks, respectively. After increasing the rolling reduction to 50%, twinning is suppressed and dislocation slip becomes the dominant deformation mode, with the lamellar grains highly elongated and aligned towards the rolling direction.Meanwhile, only one strong low-angle misorientation peak related to the prismatic slip is presented in the 50%-rolled specimen,with all other peaks disappeared. Analyses on local misorientations reveal that hardly any residual strains exist in the β-air-cooled specimen, which should be related to their sufficient relaxation during slow cooling. Residual strains introduced by 10% rolling are heterogeneously distributed near grain/twin boundaries while heavier deformation(50% rolling) produces much larger residual strains pervasively existing throughout the specimen microstructure. | CHAI LinJiang XIA JiYing ZHI Yan GOU YinNing CHEN LiangYu YANG ZhiNan GUO Ning | 2018 | Science China(Technological Sciences)2018，61，9： | 3 |
| 13 | Experiment on Machinability of Ti2AlNb Intermetallic Alloy显示文摘Ti2AlNb intermetallic alloy is a newly developed high-temperature resistant structural material due to its excellent material and mechanical properties,which also make it to be one of the most difficult-to-cut materials.In order to study the machinability of Ti2AlNb alloy,a series of turning experiments of Ti2AlNb alloy with varying cutting speed and feed rate using coated carbide tools are carried out.The results associated with cutting forces,cutting temperature and tool wear are presented and discussed.Moreover,the cutting performance of Ti2AlNb alloy is evaluated in comparison with that of most commonly used Ti6Al4 Vand Inconel 718 alloys in terms of the cutting forces and cutting temperature.The comparison results show that there is a correlation between the machinability and the mechanical properties of work material properties.Additionally,considering material removal rate and tool life,the optimized machining parameters for cutting Ti2AlNb alloys using coated carbide tools are recommended. | He Linjiang Su Honghua Xu Jiuhua Zhang Liang Bai Bing | 2017 | Transactions of Nanjing University of Aeronautics and Astronautics2017，34，5： | 3 |
| 14 | WEAR AND LIFE OF PCBN TOOLS WHEN DRY-CUTTING BEARING STEEL GCr15显示文摘The wear forms and reasons of PCBN tools when dry-cutting bearing steel GCr15 are studied systematically. The effect law of the workpiece hardness on PCBN tools is gained and tool wearing with the quickest speed at the workpiece critical hardness is proved. The life equation at two kinds of workpiece hardness demonstrates that the effect of the cutting speed on the PCBN tool life is less than that of carbide tools and ceramic tools. | Liu Xianli Zhang Zhongmin Li ZhenjiaDepartment of Mechanical Engingeering, Harbin University of Science and Technology,Harbin 150080, ChinaLiu Linjiang Yuan ZhejunJilin University Harbin Institute of Technology | 2002 | Chinese Journal of Mechanical Engineering2002，15，3： | 3 |
| 15 | Simultaneous denitrifying phosphorus accumulation in a sequencing batch reactor显示文摘In order to achieve simultaneous nitrogen and phosphorus removal in the biological treatment process,denitrifying phosphorus accumulation(DNPA)and its affecting factors were studied in a sequencing batch reactor(SBR)with synthetic wastewater.The results showed that when acetate was used as the sole carbon resource in the influent,the sludge acclimatized under anaerobic/aerobic operation had good phos-phorus removal ability.Denitrifying phosphorus accumulation was observed soon when fed with nitrate instead of aeration following the anaerobic stage,which is a vital premise to DNPA.If DNPA sludge is fed with nitrate prior to the anaerobic stage,the DNPA would weaken or even disappear.At the high concen-tration of nitrate fed in the anoxic stage,the longer anoxic time needed,the better the DNPA was.Induced DNPA did not disap-pear even though an aerobic stage followed the anoxic stage,but the shorter the aerobic stage lasted,the higher the proportions of phosphorus removal via DNPA to total removal. | YUAN Linjiang HAN Wei WANG Lei YANG Yongzhe WANG Zhiying | 2007 | Frontiers of Environmental Science & Engineering2007，1，1： | 3 |
| 16 | Analytic solution to the magnetotelluric response over anisotropic medium and its discussion显示文摘In the present paper,from the second order partial differential equations for solving the magnetotelluric(MT) fields of general anisotropic medium,we first obtained the second order partial differential equations for some anisotropic media with special conductivity(e.g.diagonal anisotropy,transverse anisotropy,azimuthal anisotropy,etc.) by simplifying the electrical conductivity tensor of anisotropic medium.And then we obtained the analytic solutions to MT fields for the case of transverse and azimuthal anisotropy through converting the conductivity parameter based on that of diagonal anisotropy.We further discussed the influence of the selection of integral limit and step length on precision in solving the analytic solutions for MT fields of isotropic medium.Finally,we presented the MT responses of two transverse and azimuthal anisotropic media as well as some applications of the analytic solutions to MT fields of anisotropic medium. | QIN LinJiang YANG ChangFu CHEN Kun | 2013 | Science China Earth Sciences2013，56，9： | 3 |
| 17 | Microstructural characteristics of cold-rolled Zr-2.5Nb alloy annealed near the monotectoid temperature显示文摘A dual-phase Zr-2.5 Nb alloy was rolled at room temperature to 50% reduction and then annealed at two temperatures(560 and580°C) near the monotectoid temperature. X-ray diffraction, electron channeling contrast imaging and electron backscatter diffraction techniques were jointly used to characterize microstructural characteristics developed in the as-rolled and annealed specimens. Results show that plastic deformation occurs in both bulk α-Zr grains and thin β-Zr films during rolling, allowing large lattice strains to be accumulated in β-Zr and active dislocation slip(especially the prismatic áa?slip) to be initiated in α-Zr. During subsequent annealing at 580°C, the prior β-Zr films are transformed into submicron β-Zr particles, which lose coherency(the Burgers orientation relationship) with surrounding α grains. In the specimen annealed at 560°C, however, the prior β-Zr films are found to be decomposed into nanoscale β-Nb particles. In both the annealed specimens, the β-Zr and the β-Nb particles appeared to be linearly distributed along the rolling direction. Two types of α structures, i.e., small equiaxed crystallites formed by recovery of dislocation structures and coarse bamboo-like recrystallized grains, are revealed in the annealed specimens. Effective boundary pinning due to the dense β-phase particles is demonstrated to play a key role in forming such unusual bamboo-like grains. | CHAI LinJiang WU Hao WANG ShuYan LUAN BaiFeng WU Yue HUANG XiaoYu | 2018 | Science China(Technological Sciences)2018，61，4： | 3 |
| 18 | Bimodal plate structures induced by pulsed laser in duplex-phase Zr alloy显示文摘A duplex-phase Zr-2.5Nb alloy was treated by pulsed laser, followed by careful microstructural characterization using field emission gun scanning electron microscope and attached electron backscatter diffraction. Beneath the modification zones with common uniform α-plate structures(UPS), a layer of unreported bimodal α-plate structures(BPS) featured by coarse(submicron)plates forming multiple cores surrounded by dense fine(nanoscale) plates was found. Presence of such BPS is attributed to non-equilibrium thermodynamic conditions induced by the pulsed laser treatments. Limited diffusion of Nb due to the short pulse during laser heating allows β phases with distinctly different Nb contents to be presented: Nb-enriched prior β films and Nb-depleted β phases, transforming into the fine and the coarse plates during cooling, respectively. Orientation analyses show that both types of plates in the BPS are aroused essentially from a single β orientation, suggesting epitaxial growth of the Nb-depletedβ phases from the preexisting β films. | CHAI LinJiang WANG ShuYan WU Hao YANG ZhiNan PAN HuCheng SONG Bo GUO Ning | 2017 | Science China(Technological Sciences)2017，60，4： | 2 |
| 19 | SLC1A1-mediated cellular and mitochondrial influx of R-2-hydroxyglutarate in vascular endothelial cells promotes tumor angiogenesis in IDH1-mutant solid tumors显示文摘Muta nt isocitrate dehydrog en ase 1(mlDH1)drives tumorigenesis via produci ng on cometabolite R-2-hydroxyglutarate(R-2-HG)across various tumor types.However,mlDHl in hibitors appear only effective in hematological tumors.The therapeutic ben efit in solid tumors remains elusive,likely due to the complex tumor microenvironment.In this study,we discover that R-2-HG produced by IDH1-mutant tumor cells is preferentially imported into vascular endothelial cells and remodels mitochondrial respiration to promote tumor angiogenesis,conferring a therapeutic vulnerability in IDH1-mutant solid tumors.Mechanistically,SLC1 Alz a Na'-depe ndent glutamate tran sporter that is prefere ntially expressed in en dothelial cells,facilitates the in flux of R-2-HG from the tumor microenvironment into the endothelial cells as well as the intracellular trafficking of R-2-HG from cytoplasm to mitochondria.R-2-HG hijacks SLC1A1 to promote mitochondrial Na^(+)/Ca^(2+)exchange,which activates the mitochondrial respiratory chain and fuels vascular en dothelial cell migratio n in tumor an giogenesis.SLC1A1 deficiency in mice abolishes mlDHl-promoted tumor an giogenesis as well as the therapeutic benefit of mlDHl in hibitor in solid tumors.Moreover,we report that HH2301,a newly discovered mlDHl inhibitor,shows promising efficacy in treating IDH1-mutant cholangiocarcinoma in preclinical models.Together,we identify a new role of SLC1A1 as a gatekeeper of R-2-HG-mediated crosstalk between IDH1-mutant tumor cells and vascular en dothelial cells,and dem on strate the therapeutic potential of mlDHl in hibitors in treating IDH1-muta nt solid tumors via disrupting R-2-HG-promoted tumor angiogenesis. | Xiaomin Wang Ziqi Chen Jun Xu Shuai Tang Nan An Lei Jiang Yixiang Zhang Shaoying Zhang Qingli Zhang Yanyan Shen Shijie Chen Xiaojing Lan Ting Wang Linhui Zhai Siyuwei Cao Siqi Guo Yingluo Liu Aiwei Bi Yuehong Chen Xiameng Gai Yichen Duan Ying Zheng Yixian Fu Yize Li Liang Yuan Linjiang Tong Kun Mo Mingcheng Wang Shu-Hai Lin Minjia Tan Cheng Luo Yi Chen Jia Liu Qiansen Zhang Leping Li Min Huang | 2022 | Cell Research2022，32，7： | 2 |
| 20 | ~1H MAS NMR spectra of kao-linite/formamide intercalation compound显示文摘The high spinning speed 1H magic angle spinning nuclear magnetic resonance (1H MAS NMR) technique was employed to distinguish the two groups of surface hy-droxyls of kaolinite and investigate the intercalation mechanism of kaolinite/formamide compound. The proton chemical shifts of the inner hydroxyl and inner surface hydroxyl of kaolinte are in the range of δ-1.3--0.9 and δ 2.4-3.0 respectively. After formamide intercalation three proton peaks were detected. The proton peak of the inner surface hydrox-yls of the intercalation compound shifts to high-field with δ2.3-2.7, which is assigned to the formation of the hydrogen bond between the inner surface hydroxyl and formamide carbonyl group. Whereas, the proton peak of the inner hydroxyl shifts to δ-0.3 toward low-field, that is attributed to van der Waal’s effect between the inner hydroxyl proton and the amino group proton of the formamide which may be keyed into the ditrigonal hole of the kaolinite. The third peak, additional proton peak, is in the | Linjiang Wang Daqing Wu Peng Yuan Zhiwei Chen Zhong Chen | 2002 | Chinese Science Bulletin2002，47，6： | 1 |
