| 1 | Influence of Al-Ti-B addition on the microstructure and mechanical properties of A356 alloys显示文摘The mechanical properties (σb,σ0.2,and δ) and fracture behavior of tensile specimens of the refined A356 alloys were investigated as a function of the addition level of Al-Ti-B master alloy under both as-cast and T6 heat-treated conditions. The results show that as the addition level of Al-5Ti-1B master alloy increases from 0.1 wt.% to 5.0 wt.%,the mechanical properties of refined A356 alloys improve steadily and then decrease slightly under both as-cast and T6 heat-treated conditions. Also,they display excellent mechanical properties with σb = 231.30-258.30 MPa,σ0.2 =134.00-155.50 MPa,and δ = 8.5%-11.75% at T6 heat-treated state. The excellent mechanical properties of refined A356 alloys are ascribed to the formation of α-Al equiaxed dendrites,the improvement of eutectic structure from needle/plate-like to short-lathy/block-shaped,and the Mg2Si aging precipitation phase after T6 heat treatment. The fracture surface examined by SEM exhibits a mixed fracture mode of refined A356 alloys at as-cast state,while it reveals a ductile fracture mode after T6 heat treatment. | Zhu Man Yang Gencang Yao Lijuan Cheng Suling Zhou Yaohe | 2009 | Rare Metals2009，28，2： | 11 |
| 2 | Microstructures and Morphology Evolution of Icosahedral Phase of As-cast Mg_(67.4)Zn_(28.9)Y_(3.7) Ternary Alloy Subjected to the Pouring Temperature显示文摘The microstructure,chemical composition and morphology evolution of icosahedral quasicrystalline phase of Mg67.4Zn28.9Y3.7 ternary alloy were investigated in detail at different pouring temperatures by X-ray diffraction(XRD),scanning electron microscopy(SEM) and energy-dispersive spectrum(EDS).Low interfacial energy favors the formation of I-phase.The experimental results show that the primary I-phase reveals petal-shaped with five and six branches,where each branch has facetted growth morphology with the size ranging from 50 to 100 μm.As the temperature decreases,the polygon-shaped I-phase forms,attributed to the decomposition of branch of petal-shaped I-phase,and then it grows bigger and some of the fine polygons join together to form large polygons.Besides these,(α-Mg+I-phase) eutectic structures disappear and the relative amount of Mg7Zn3 phase increases as the pouring temperature decreases.The chemical composition and morphology evolution of I-phase were also discussed. | Man Zhu Gencang Yang Diqing Wan Suling Cheng Yaohe Zhou | 2009 | Journal of Materials Science & Technology2009，25，4： | 1 |

| 7 | Effect of Bath pH on the Squareness of Electroless CoNiWP Magnetic Films显示文摘Electroless CoNiWP magnetic films were prepared by varying the bath pH and then characterized by energy dispersive X-ray analysis,X-ray diffraction and magnetic force microscopy.It has been found that the mi- crostructure and the magnetic properties of films were influenced greatly by the bath pH.At the bath pH 8.06, the grain size and coercivity of the films reach maximum,while the squareness(M_r/M_s)of MH curves reaches minimum.The Henkel plots indicates that the exchange-coupling interaction is very weak at this pH,which may be caused by phase-separation and large grain size,and then results in the lowest squareness.At pH above 8.5,obvious exchange-coupling interaction is observed because of the inexistence of phase-separation and the refinement of grain size. | Haibin CHENG Shuai XU Wenyu ZHAO Suling ZHAO Pengcheng ZHAI Zhigang SUNand Qingjie ZHANGt Pengcheng ZHAI Zhigang SUN Qingjie ZHANG | 2008 | Journal of Materials Science & Technology2008，24，5： | 0 |
| 8 | An integrative drug repositioning framework discovered a potential therapeutic agent targeting COVID-19显示文摘The global spread of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)requires an urgent need to find effective therapeutics for the treatment of coronavirus disease 2019(COVID-19).In this study,we developed an integrative drug repositioning framework,which fully takes advantage of machine learning and statistical analysis approaches to systematically integrate and mine large-scale knowledge graph,literature and transcriptome data to discover the potential drug candidates against SARS-CoV-2.Our in silico screening followed by wet-lab validation indicated that a poly-ADP-ribose polymerase 1(PARP1)inhibitor,CVL218,currently in Phase I clinical trial,may be repurposed to treat COVID-19.Our in vitro assays revealed that CVL218 can exhibit effective inhibitory activity against SARS-CoV-2 replication without obvious cytopathic effect.In addition,we showed that CVL218 can interact with the nucleocapsid(N)protein of SARS-CoV-2 and is able to suppress the LPS-induced production of several inflammatory cytokines that are highly relevant to the prevention of immunopathology induced by SARS-CoV-2 infection. | Yiyue Ge Tingzhong Tian Suling Huang Fangping Wan Jingxin Li Shuya Li Xiaoting Wang Hui Yang Lixiang Hong Nian Wu Enming Yuan Yunan Luo Lili Cheng Chengliang Hu Yipin Lei Hantao Shu Xiaolong Feng Ziyuan Jiang Yunfu Wu Ying Chi Xiling Guo Lunbiao Cui Liang Xiao Zeng Li Chunhao Yang Zehong Miao Ligong Chen Haitao Li Hainian Zeng Dan Zhao Fengcai Zhu Xiaokun Shen Jianyang Zeng | 2021 | Signal Transduction and Targeted Therapy2021，6，5： | 0 |
| 9 | Global Rainstorm Disaster Risk Monitoring Based on Satellite Remote Sensing显示文摘Methods of rainstorm disaster risk monitoring(RDRM)based on retrieved satellite rainfall data are studied.Due to significant regional differences,the global rainstorm disasters are not only affected by geography(such as topography and surface properties),but also by climate events.It is necessary to study rainstorm disaster-causing factors,hazard-formative environments,and hazard-affected incidents based on the climate distribution of precipitation and rainstorms worldwide.According to a global flood disaster dataset for the last 20 years,the top four flood disaster causes(accounting for 96.8%in total)related to rainstorms,from most to least influential,are heavy rain(accounting for 61.6%),brief torrential rain(16.7%),monsoonal rain(9.4%),and tropical cyclone/storm rain(9.1%).A dynamic global rainstorm disaster threshold is identified by using global climate data based on 3319 rainstorm-induced floods and rainfall data retrieved by satellites in the last 20 years.Taking the 7-day accumulated rainfall,3-and 12-h maximum rainfall,24-h rainfall,rainstorm threshold,and others as the main parameters,a rainstorm intensity index is constructed.Calculation and global mapping of hazard-formative environmental factor and hazard-affected body factor of rainstorm disasters are performed based on terrain and river data,population data,and economic data.Finally,a satellite remote sensing RDRM model is developed,incorporating the above three factors(rainstorm intensity index,hazard-formative environment factor,and hazard-affected body factor).The results show that the model can well capture the rainstorm disasters that happened in the middle and lower reaches of the Yangtze River in China and in South Asia in 2020. | Suling REN Xiuzhen HAN Jun YANG Shihao TANG Yang ZHANG Tianchan SHAN Cheng LIU | 2022 | Journal of Meteorological Research2022，36，1： | 0 |
