| 1 | Mechanical Behaviour and Microstructure Evolution of Superplastic Mg-8.4 wt pct Li Alloy and Effect of Grain Size and Phase Ratio on Its Elongation显示文摘Mechanical properties and microstructure evolution of Mg-8.4 wt pct Li alloy have been investi- gated. The superplastic elongation-to-failure 920% at 573 K and initial strain rate of 5 × 10-4 s-1 at low nominal stress 2 MPa has been demonstrated. It was shown through optical microstructure that the average grain sizes at gauge length section before and after superplastic tension and at grip section were 7.5 μm, 31.7 μm and 20 μm respectively, indicating significant deformation induced grain growth and static grain growth. Comparison of experiment data with published data for superplastic Mg-Li alloys shows that fine grain size and about 50 to 50 phase ratio contribute to achieving the largest superplasticity. Some related research works in other alloys are compiled and further evidences to such theoretic argument are provided. | Cao, FR Cui, JZ Wen, JL Lei, F | 2000 | Journal of Materials Science & Technology2000，16，1： | 5 |
| 2 | Voltage-induced penetration effect in liquid metals at room temperature显示文摘Room-temperature liquid metal is discovered to be capable of penetrating through macro-and microporous materials by applying a voltage.The liquid metal penetration effects are demonstrated in various porous materials such as tissue paper;thick and fine sponges;fabrics;and meshes.The underlying mechanism is that the high surface tension of liquid metal can be significantly reduced to near-zero due to the voltage-induced oxidation of the liquid metal surface in a solution.It is the extremely low surface tension and gravity that cause the liquid metal to superwet the solid surface^leading to the penetration phenomena.These findings offer new opportunities for novel microfluidic applications and could promote further discovery of more exotic fluid states of liquid metals. | Frank F Yun Zhenwei Yu Yahua He Lei Jiang Zhao Wang Haoshuang Gu Xiaolin Wang | 2020 | National Science Review2020，7，2： | 3 |
| 3 | Development of a reverse transcription quantitative polymerase chain reaction-based assay for broad coverage detection of African and Asian Zika virus lineages显示文摘The Zika virus(ZIKV) is an arbovirus that has spread rapidly worldwide within recent times. There is accumulating evidence that associates ZIKV infections with Guillain-Barré Syndrome(GBS) and microcephaly in humans. The ZIKV is genetically diverse and can be separated into Asian and African lineages. A rapid, sensitive, and specific assay is needed for the detection of ZIKV across various pandemic regions. So far, the available primers and probes do not cover the genetic diversity and geographic distribution of all ZIKV strains. To this end, we have developed a one-step quantitative reverse transcription polymerase chain reaction(qRT-PCR) assay based on conserved sequences in the ZIKV envelope(E) gene. The detection limit of the assay was determined to be five RNA transcript copies and 2.94 × 10^(–3) 50% tissue culture infectious doses(TCID50) of live ZIKV per reaction. The assay was highly specific and able to detect five different ZIKV strains covering the Asian and African lineages without nonspecific amplification, when tested against other flaviviruses. The assay was also successful in testing for ZIKV in clinical samples. Our assay represents an improvement over the current methods available for the detection ZIKV and would be valuable as a diagnostic tool in various pandemic regions. | Yang Yang Gary Wong Baoguo Ye Shihua Li Shanqin Li Haixia Zheng Qiang Wang Mifang Liang George F Gao Lei Liu Yingxia Liu Yuhai Bi | 2017 | Virologica Sinica2017，32，3： | 3 |
| 4 | Methods for measuring soil infiltration:State of the art显示文摘Soil infiltration is the process by which water on the soil surface penetrates the soil.Quantifying the soil infiltration capacity(soil infiltrability)is very important for determining components of the hydrological modeling,irrigation design and many other natural or man made processes.In this paper,commonly used methods for soil infiltration rate measurement with their principles and application conditions are introduced.The advantages and disadvantages of each method under various application conditions are discussed for comparison.Three new methods for soil infiltrability measurement,including the corresponding algorithm models,and the experimental apparatus and procedures are introduced.These analyses should facilitate the choice of method used for soil infiltrability measurement. | Mao Lili V F Bralts Pan Yinghua Liu Han Lei Tingwu | 2008 | International Journal of Agricultural and Biological Engineering2008，1，1： | 2 |
