1Fluid/melt in continental deep subduction zones: Compositions and related geochemical fractionations显示文摘Plate subduction is the most magnificent process in the Earth. Subduction zones are important sites for proceeding matter- and energy- transports between the Earth's surface and the interior, continental crust growth, and crust-mantle interactions. Besides, a number of geological processes in subduction zones are closely related to human beings' daily life, such as volcanic eruptions and earthquakes, formation of mineral deposits. Subduction process thus has long been the centric topic of Earth sciences. The finding in 1980 s that continental crust could be subducted to mantle depths is a revolutionary progress in plate tectonic theory. Compared to oceanic crust, continental crust is colder, drier, lighter, and much more geochemically/isotopically heterogeneous. Hence, continental subduction process would affect the structure, compositions and evolutions of the overlying mantle wedge even more. During continental subduction and subsequent exhumation, fluids and melts can be generated in the(de)hydration process and partial melting process, respectively. These melts/fluids play important roles in crust-mantle interactions, elemental migrations, isotopic fractionations, and mantle metasomatism. By summarizing recent research works on subduction zones in this paper, we present a review on the types, physicochemical conditions and compositions of fluids/melts, as well as the migration behaviors of fluid-related characteristic elements(Nb-Ta-V) and the fractionation behaviors of non-traditional stable isotopes(Li-Mg) in subduction zones. The aim of this paper is to provide the readers an update comprehensive overview of the melt/fluid activities in subduction zones and of Li-Mg isotope systematics in subduction-related rocks and minerals.XIAO YiLin SUN He GU HaiOu HUANG Jian LI WangYe LIU Lei 2015Science China Earth Sciences2015,58,9:12
2Acupuncture preconditioning protects hippocampal neurons from transient ischemia/reperfusion injury显示文摘The present study established a model of brain ischemia in aged rats using four-vessel occlusion.We observed hippocampal CA1 neuronal apoptosis and apoptosis-mediated protease caspase-3 expression following preconditioning of electroacupuncture at Baihui(GV 20).Our results showed that the number of hippocampal CA1 normal neurons was decreased,and degenerated neurons were increased 12 hours to 3 days following cerebral ischemia/reperfusion.The number of hippocampal CA1 apoptotic neurons and caspase-3-positive neurons in rats with cerebral ischemia/reperfusion injury was significantly decreased following acupuncture preconditioning.Acupuncture preconditioning protects aged rats against ischemia/reperfusion injury by regulating caspase-3 protein expression.Mingshan Wang Haipeng Zhou Fei Shi Shilong Ma Yanlin Bi Yuqiu Liu Hong Liu Haiou Li 2011Neural Regeneration Research2011,6,15:12
3Microstructure and Mechanical Properties of Al_2O_3/ZrO_2 Directionally Solidified Eutectic Ceramic Prepared by Laser 3D Printing显示文摘Directionally solidified eutectic ceramics such as(Al)_2O_3/ZrO_2 are promising structural materials for applications in harsh environment with an ultrahigh temperature. In this work, through adopting assistant heating laser 3D printing,(Al)_2O_3/ZrO_2eutectic samples were manufactured with suppressing the formation of cracks. The dependence of the average rod spacing(λav) on the scanning rate(V) follows a relation with λav V0.5= 1 μm1.5s–0.5. Typical eutectic microstructures, so-called complex regular, were analyzed with respect to its evolution with modulating the growth conditions. Formation mechanism of the solidification defect, shrinkage porosity, was discussed and the defect is found to be significantly suppressed by optimizing the solidification parameters. The maximum hardness and fracture toughness are measured to be 16.7 GPa and 4.5 MPa m1/2, respectively. The interplay between the propagation of cracks and the (Al)_2O_3/ZrO_2 interface is discussed.Zhi Liu Kan Song Bo Gao Tian Tian Haiou Yang Xin Lin Weidong Huang 2016Journal of Materials Science & Technology2016,32,4:12
4High strength and ductility of 34CrNiMo6 steel produced by laser solid forming显示文摘Because of the excellent mechanical properties of 34 CrNiMo6 steel, it is widely used in high-value components. Many conventional approaches to strengthening-steels typically involve the loss of useful ductility.In this study, 34 CrNiMo6 Steel having high strength and ductility is produced by laser solid forming(LSF)with a quenching-tempering(QT) treatment. Tempering of bainite is mainly by solid phase transformation in the previous LSF layers during the LSF process. The stable microstructure of LSF consists of ferrite and fine carbides. The microstructure transfers to tempered sorbite after heat-treatment. The tensile properties of the LSF steel meet those of the wrought standard. The UTS and elongation of LSF sample at 858 MPa, 19.2%, respectively, are greater than those of the wrought. The QT treatment enhanced the ultimate tensile strength and yield strength of the LSF sample. The ultimate tensile strength, yield strength, reduction in area, and elongation of the LSF+QT sample at 980 MPa, 916 MPa, 58.9%, and 13.9%,respectively, are greater than those of the wrought standard. The yield strength of the LSF+QT sample is approximately 1.27 times that of the wrought. The LSF samples failed in a ductile fracture mode, while the LSF+QT samples showed mixed-mode failure. The defects have only a small effect on the tensile properties owing to the excellent ductility of the LSF sample.Chunping Huang Xin Lin Fencheng Liu Haiou Yang Weidong Huang 2019Journal of Materials Science & Technology2019,35,2:6
5ASCS Online Fault Detection and Isolation Based on an Improved MPCA显示文摘Multi-way principal component analysis(MPCA)has received considerable attention and been widely used in process monitoring.A traditional MPCA algorithm unfolds multiple batches of historical data into a two-dimensional matrix and cut the matrix along the time axis to form subspaces.However,low efficiency of subspaces and difficult fault isolation are the common disadvantages for the principal component model.This paper presents a new subspace construction method based on kernel density estimation function that can effectively reduce the storage amount of the subspace information.The MPCA model and the knowledge base are built based on the new subspace.Then,fault detection and isolation with the squared prediction error(SPE)statistic and the Hotelling(T2)statistic are also realized in process monitoring.When a fault occurs,fault isolation based on the SPE statistic is achieved by residual contribution analysis of different variables.For fault isolation of subspace based on the T2 statistic,the relationship between the statistic indicator and state variables is constructed,and the constraint conditions are presented to check the validity of fault isolation.Then,to improve the robustness of fault isolation to unexpected disturbances,the statistic method is adopted to set the relation between single subspace and multiple subspaces to increase the corrective rate of fault isolation.Finally fault detection and isolation based on the improved MPCA is used to monitor the automatic shift control system(ASCS)to prove the correctness and effectiveness of the algorithm.The research proposes a new subspace construction method to reduce the required storage capacity and to prove the robustness of the principal component model,and sets the relationship between the state variables and fault detection indicators for fault isolation.PENG Jianxin LIU Haiou HU Yuhui XI Junqiang CHEN Huiyan 2014Chinese Journal of Mechanical Engineering2014,27,5:3
6Fabrication of 150-nm Al_(0.48)In_(0.52)As/Ga_(0.47)In_(0.53)As mHEMTs on GaAs substrates显示文摘High performance 150-nm gate-length metamorphic Al0.48In0.52As/Ga0.47In0.53 As high electron mobility transistors(mHEMTs) with very good device performance have been successfully fabricated.A T-shaped gate is fabricated by using a combined technique of optical and e-beam photolithography,which is beneficial to decreasing parasitic capacitance and parasitic resistance of the gate.The ohmic contact resistance R c is as low as 0.03 mm when using a novel ohmic contact metal system(Ni/Ge/Ti/Au).The devices exhibit excellent DC and RF performance.A peak extrinsic transconductance of 775 mS/mm and a maximum drain current density of 720 mA/mm are achieved.The unity current gain cut-off frequency(fT) and the maximum oscillation frequency(f max) are 188.4 and 250 GHz,respectively.WU XiaoFeng LIU HongXia LI HaiOu LI Qi HU ShiGang XI ZaiFang ZHAO Jin 2012Science China(Physics,Mechanics & Astronomy)2012,55,12:2
7Precisely installing gold nanoparticles at the core/shell interface of micellar assemblies of triblock copolymers显示文摘Two reduction-cleavable ABA triblock copolymers possessing two disulfide linkages,PMMA-ssPMEO_3MA-ss-PMMA and PDEA-ss-PEO-ss-PDEA were synthesized via facile substitution reactions from homopolymer precursors,where PMMA,PMEO_3MA,PDEA,and PEO represent poly(methyl methacrylate),poly(tri(ethylene glycol) monomethyl ether methacrylate,poly(2-(diethylamino)ethyl methacrylate),and poly(ethylene oxide),respectively.Spherical micelles were obtained through supramolecular self-assembly of these two triblock copolymers in aqueous solutions.The resultant micelles with abundant disulfide bonds could serve as soft templates and precisely accommodate gold nanoparticles in the core/shell interface as a result of the formation of Au-S bonds.Kangning Zhu Zhiyuan Zhu Haiou Zhou Jingyan Zhang Shiyong Liu 2017Chinese Chemical Letters2017,28,6:2

14Enhanced Charge Separation of a-Bi2O3-BiOI Hollow Nanotube for Photodegradation Antibiotic Under Visible Light显示文摘It is highly desirable to exploit semiconductor materials with high photocatalytic degradation activity,es-pecially bismuth oxyhalide semiconductor photocatalysts with special layered structure and suitable bandgap width.The low utilization rate of visible light and high recombination rate of photogenerated electron-hole of BiOl photo catalyst severely restrict its development.Herein,a heterojunction photocatalyst of a-Bi2O3-BiOI hollow nanotube was prepared by electrospinning method,solvothermal method and ion-exchange method.The a-Bi2O3-BiOI(BB-4 the stirring time of Bi2O3 in KI solution was 4 h)exhibited the best photocatalytic performance towards degrading the tetracycline hydrochloride(TC)solution,which could remove 85%of TC(10 mg/L)in 2 h under visible light irradia-tion.The estimated hrc of a-BiO-BiOI(BB-4)was ca.3.9 and 1.8 times as much as that of a-Bi2O3 and pure BiOI respectively.It indicated that the formation of a-BizO3-BiOl heterojunction can significantly improve the separatior efficiency of photogenerated electron-hole pairs,therefore the photocatalytic ability was enhanced.Furthermore,a corresponding photocatalytic mechanism was proposed that Oz radical and holes are the main active components in the photodegradation through trapping experiment.ZHANG Pengfei LIU Huan LIANG Haiou BAI Jie LI Chunping 2020Chemical Research in Chinese Universities2020,36,6:1
