| 1 | Effects of Y on the Microstructure, Mechanical and Bio-corrosion Properties of Mg-Zn-Ca Bulk Metallic Glass显示文摘The micro-alloying effects of Y on the microstructure, mechanical properties, and bio-corrosion behavior of Mg69-xZn27Ca4Yx(x= 0, 1, 2 at.%) alloys were investigated through X-ray diffraction, compressive tests,electrochemical treatments, and immersion tests. The Mg69Zn27Ca4 alloy was found to be absolutely amorphous, and its glass-forming ability decreased with the addition of Y. The Mg68Zn27Ca4Y1 alloy exhibited an ultrahigh compressive strength above 1010 MPa as well as high capacity for plastic strain above 3.1%.Electrochemical and immersion tests revealed that these Y-doped MgeZ neC a alloys had good bio-corrosion resistance in simulated body fluid(SBF) at 37℃. The results of the cytotoxicity test showed high cell viabilities for these alloys, which means good bio-compatibility. | Jingfeng Wang Yang Li Song Huang Yiyun Wei Xingfeng Xi Kaiyong Cai Fusheng Pan | 2014 | Journal of Materials Science & Technology2014，30，12： | 8 |
| 2 | Conceptual and theoretical dimensions of biodiversity research in China: examples from plants显示文摘The search for the underlying mechanisms of species origin,maintenance and extinction is among the highest priorities in biodiversity science.In parallel with the rapid accumulation of empirical evidence for existing theories in this field in China[1],numerous conceptual and theoretical achievements of basic biodiver sity science have been made,accompanied by methodological breakthroughs. | Chengjin Chu Lei Chen Pengfei Fan Ziwen He Yuanzhi Li Jinbao Liao Xubing Liu Kechang Niu Xingfeng Si Shaopeng Wang Xinqiang Xi | 2021 | National Science Review2021，8，7： | 0 |
