4TiZr-base Bulk Metallic Glass with over 50 mm in Diameter显示文摘Low-cost TiZr-base bulk metallic glasses(BMGs)(Ti36.1Zr33.2Ni5.8Be24.9)100-xCux(x=5,7 and 9) with a maximum size of over 50 mm in diameter were developed by optimizing the alloy composition.The idea is initiated by selecting a particular microstructure comprising primary β-Ti dendrite and amorphous phase.Afterwards,based on this composition of amorphous phase,a class of TiZr-base bulk metallic glasses was designed step by step to reach the optimum composition range.The glass transition temperature(Tg),initial crystallization temperature(Tx) and width of supercooled region(△T) of(Ti36.1Zr33.2Ni5.8Be24.9)91Cu9 BMG are 611,655 and 44 K,respectively.The(Ti36.1Zr33.2Ni5.8Be24.9)91Cu9 BMG exhibits low density of 5.541 g·cm-3 and high compressive fracture strength of 1800 MPa,which promises the potential application as structural materials.M.

7RESEARCH AND DEVELOPMENT OF HIGH TEMPERATURESTRUCTURAL MATERIALS FOR AERO-ENGINE APPLICATIONS显示文摘The status of research, development of superalloys and materials processing & fabrication technologies for aero-engine applications in China Aviation Industry, with an emphasis on recent achievements at BIAM including directionally solidified and single crystal superalloys for blade and vane applications, wrought superalloys for aero-engine disks and rings, and powder metallurgy (PM) superalloys for high performance disk applications were described. It was also reviewed the development of new class of high temperature structural materials, such as structural intermetallics, and advanced material processing technologies including rapid solidification, spray forming and so on. The trends of research and development of the above mentioned superalloys and processing technologies are outlined. Cast, wrought and PM superalloys are the workhorse materials for the hot section of current aero-engines. New high temperature materials and advanced processing technologies have been and will be the subject of study.

8Contamination by Organochlorine Pesticides in the Estuaries of Southeast China显示文摘Persistent organic pollutants(POPs) such as organochlorine pesticides are of global concern due to their widespread occurrence and persistence. This paper reports recent research studying the distribution and fate of organochlorine pesticides in the Jiulong River, the Minjiang River and the Pearl River estuaries in Southeast China. Eighteen organochlorine pesticides were extracted from water, pore water and sediment samples, followed by analysis by GC ECD. The results showed that the contamination levels were similar in these three estuaries. The levels of the total organochlorine pesticides in porewater were significantly higher than those in surface water, due to the high affinity of these hydrophobic compounds for sediment phase. Among the hexachlorocyclohexane(HCH) compounds, β HCH was found to be the most important isomer. The analysis of 1,1,1 trichloro 2,2 bis chlorophenyl ethane(DDT) and its metabolites showed that 1,1 dichloro 2[ o chlorophenyl] 2[ p chlorophenyl] ethylene(DDE) was dominant in the group.Z. L.

9INFLUENCE OF NaCl DEPOSITION ON ATMOSPHERIC CORROSION OF A3 STEEL IN THE PRESENCE OF SO_2显示文摘The regularities of atmospheric corrosion of A3 steel deposited with different amountof NaCl exposed to the air containing 1ppm SO2 at 80% RH and 25℃ were studied inlaboratory. NaCl can accelerate the corrosion of A3 steel obviously under such con-dition. The relationship between the weight loss of A3 steel and the amount of NaCldeposition can be well described by using a quadratic function. Fourier transform in-frared spectroscopy (FTIR), X-ray diffraction (XRD), Scanning electron microscopyand electron dispersion X-ray analysis (SEM/EDAX) were used to characterize thecorrosion products. In the absence of NaCl, FeSO4 xH2O is the dominant corro-sion products, while Fe3O4, FeSO4@ H2O, β-FeOOH and γ-FeOOH dominate in thepresence of NaCl.Q. Qu, C.W. Yan, L. Zhang , Y. Wan and C.N.

11Progress of applied research on TiO_2 photocatalysis-membrane separation coupling technology in water and wastewater treatments显示文摘Photocatalysis-membrane separation coupling technology has been a heavily researched area in water and wastewater treatment during recent years. The membrane separation process allows the photocatalyst to be easily separated, recovered and reused. More significantly, the membrane is efficient to maintain high flux of membranes as the photocatalyst can reduce the membrane fouling problem which is a hindrance in the development of membrane process. Moreover, some synergistic effects can also be produced, and thus the efficiency of water treatment is enhanced greatly. A comprehensive review of photocatalysis-membrane separation coupling technology is conducted with an insight into its configurations, theories involved, characteristics, and factors that influ-ence the coupling technology. In view of the existing problems, the prospects for future development are also proposed.XIAO YuTang XU ShuangShuang LI ZhiHua AN XiaoHong ZHOU Lei ZHANG YongLai FU Q.

12STUDY ON THE PREDICTIVE METHOD OF BUCKLING DEFORMATIONS OF THIN-PLATE WELDED STRUCTURES显示文摘The buckling formation and influence factors during welding thin - plated structures were investigated based on finite element methods, An engineering treatment method for prdicating the buckling distor- tion was proposed in here. It was used the equivalent applied thermal - load to simulate the welding residual stress,therefore the calculation of complex welding distoriton can be transformed into 3D elas- tic structural applied- load analyses, which can reduce the quantities of calculating works effectively. The validation of the method was verified by comparison of the numerical simulation and experimental results. The simulation of buckling distorition for side - walled structrues of paseenger train was per- formed and the calculation was in agreement with measuring results in general. It was shown that the main factors for producing the buckling were the intermittent fillet and ping the during welding the stiffened beams and columns to the panel.The existence of the free edge of panels would reduce the crit- ical buckling stress and enlarge the deflection obviously,but the continuous weld in closed frames didn’ t degrade the buckling situation.X.

15Hsa-miR-1246, hsa-miR-320a and hsa-miR-196b-5p inhibitors can reduce the cytotoxicity of Ebola virus glycoprotein in vitro显示文摘Ebola virus(EBOV)causes a highly lethal hemorrhagic fever syndrome in humans and has been associated with mortality rates of up to 91%in Zaire,the most lethal strain.Though the viral envelope glycoprotein(GP)mediates widespread inflammation and cellular damage,these changes have mainly focused on alterations at the protein level,the role of microRNAs(miRNAs)in the molecular pathogenesis underlying this lethal disease is not fully understood.Here,we report that the miRNAs hsa-miR-1246,hsa-miR-320a and hsa-miR-196b-5p were induced in human umbilical vein endothelial cells(HUVECs)following expression of EBOV GP.Among the proteins encoded by predicted targets of these miRNAs,the adhesion-related molecules tissue factor pathway inhibitor(TFPI),dystroglycan1(DAG1)and the caspase 8 and FADD-like apoptosis regulator(CFLAR)were significantly downregulated in EBOV GP-expressing HUVECs.Moreover,inhibition of hsa-miR-1246,hsa-miR-320a and hsa-miR-196b-5p,or overexpression of TFPI,DAG1 and CFLAR rescued the cell viability that was induced by EBOV GP.Our results provide a novel molecular basis for EBOV pathogenesis and may contribute to the development of strategies to protect against future EBOV pandemics.SHENG MiaoMiao ZHONG Ying CHEN Yang DU JianChao JU XiangWu ZHAO Chen ZHANG GuiGen ZHANG LiFang LIU KangTai YANG Ning XIE Peng LI DangSheng ZHANG Michael Q.
