| 1 | The development of super-high collapse resistant casing显示文摘Super-high collapse resistant casings were developed by using Ti,Nb and V microalloyed CrMo steel and cross rolling techniques.A transmission electron microscope(TEM)and X-ray diffractometer were used to observe the characteristics of the microstructure.It was found that the(111)texture and the nano-scale precipitates distribute in a way that is beneficial to the collapse resistance,and the collapse strength of the prepared casing had a measurement, which was approximately 60% higher than the API standard value.A design concept to attain super-high collapse resistance is proposed based on the texture design and microstructure control. | Tian Qingchao Dong Xiaoming | 2008 | Baosteel Technical Research2008，2，2： | 1 |
| 2 | Fabrication and characterization of Ba Ce_(0.8)Y_(0.2)O_(2.9)-Ce_(0.85)Sm_(0.15)O_(1.925) composite electrolytes for IT-SOFCs显示文摘The Ba Ce0.8Y0.2O2.9-Ce0.85Sm0.15O1.925 composite electrolytes were prepared with Ba Ce0.8Y0.2O2.9(BCY) and Ce0.85Sm0.15O1.925(SDC). The SDC and BCY powders were mixed in the weight ratio of 95:5, 85:15, and 75:25, respectively(named as BS95, BS85, and BS75). Because of the composite effect between the SDC and BCY phases, the BS95 and BS85 exhibit improved conductivity compared with the pure SDC and BCY. The conductivity of BS95 is higher than that of BS85, indicating that the composite effect of BS95 is greater than that of BS85. Nevertheless, the composite effect in BS75 does not exist. Hence, we conclude that the composite effect in the BCY-SDC composites will decrease with the increase of the amount of BCY and even disappear when the amount of BCY exceeds a certain value. In our case, the optimum composition of the composite electrolyte is 95 wt% SDC and 5 wt% BCY. The BS95 has the highest conductivity(σ1t=0.07808 S cm-1, at 800 °C) and the fuel cell based on the BS95 shows the best performance(the maximum power density reaches as high as 526 mw cm-2 at 750 °C). The encouraging results suggest that the BCY-SDC composites are the very promising electrolyte materials for IT-SOFCs. | Ji Yu Ning Tian Yufu Deng Guannan Li Ling Liu Liying Cheng Peng Gao Qingchao Pan Yuancheng Wang Xiuyan Chen Kezhen Qi | 2015 | Science China Chemistry2015，58，3： | 1 |

| 4 | Mechanical behavior of electric resistance welded pipes in pipe-making process显示文摘The changes in the mechanical behavior of electric resistance welded(ERW) pipes before and after the cage roll forming process were investigated through tensile experiments.It is found that the Bauschinger effect does not exist in the pipe product,while the work hardening effect introduced by pipe-making is the direct cause of the mechanical changes.The prestrain introduced during different pipe-making processes are accumulative to the work hardening effect.And the increment of the yield strength for making 244.48×8.94 pipe is approximately 45 MPa,higher than that of hot-rolled plates.It is verified that the strain ε=tD-t is an efficient index representing the work hardening effect from the engineering viewpoint. | TIAN Qingchao DONG Xiaoming SHI Hongde DING Weijun | 2010 | Baosteel Technical Research2010，4，3： | 1 |

| 6 | Avian influenza viruses suppress innate immunity by inducingtrans-transcriptional readthrough via SSU72显示文摘Innate immunity plays critical antiviral roles. The highly virulent avian influenza viruses (AIVs) H5N1, H7N9, and H5N6 can betterescape host innate immune responses than the less virulent seasonal H1N1 virus. Here, we report a mechanism by whichtranscriptional readthrough (TRT)-mediated suppression of innate immunity occurs post AIV infection. By using cell lines, mouselungs, and patient PBMCs, we showed that genes on the complementary strand (“trans” genes) influenced by TRT were involved inthe disruption of host antiviral responses during AIV infection. The trans-TRT enhanced viral lethality, and TRT abolishmentincreased cell viability and STAT1/2 expression. The viral NS1 protein directly bound to SSU72, and degradation of SSU72 inducedTRT. SSU72 overexpression reduced TRT and alleviated mouse lung injury. Our results suggest that AIVs infection induce TRT byreducing SSU72 expression, thereby impairing host immune responses, a molecular mechanism acting through the NS1-SSU72-trans-TRT-STAT1/2 axis. Thus, restoration of SSU72 expression might be a potential strategy for preventing AIV pandemics. | Yan Zhao Fengming Huang Zhen Zou Yuhai Bi Yang Yang Cong Zhang Qiang Liu Daozhen Shang Yiwu Yan Xiangwu Ju Song Mei Peng Xie Xiao Li Mingyao Tian Shuguang Tan Huijun Lu Zongsheng Han Kangtai Liu Yuqing Zhang Junbo Liang Zhu Liang Qingchao Zhang Jiahui Chang William JLiu Cong Feng Tanshi Li Michael Q.Zhang Xiaoyue Wang George FGao Yingxia Liu Ningyi Jin Chengyu Jiang | 2022 | Cellular & Molecular Immunology2022，19，6： | 0 |
| 7 | Superelasticity of TiPdNi Alloys with and without Rare Earth Ce Addition显示文摘Ti50.6Pda0Ni19.4 and Ti51Pd2sNi21 (Ce) alloys have been prepared under various temperatures for long time annealing. Differential scanning calorimetery (DSC), X-ray diffraction (XRD) and tensile test were employed to investigate the phase transformation behavior and superelasticity of the alloys. It has been found that the phase transformation temperature of Ti50.6Pd30Ni19.4 is about 40℃ higher than that of Ti51Pd28Ni21(Ce), and do not change much with different annealed temperature. Obvious superelasticity is retained in Ti50.6Pd30Ni19.4 alloy annealed at 400℃ for 18 h, and annealing at higher temperature shows a deterioration of this property. The Ce addition in Ti51Pd28Ni21 alloy significantly delays recrystallization, increases yied strength and elastic modulus, but the superelasticity is poor. | Qingchao TIAN, Jiansheng WU and Yifeng CHENGKey Laboratory of the Ministry of Education for High Temperature Materials and Tests, School of Materials Science and Engineering, Shanghai Jiao Tong Univ., Shanghai 200030, China | 2003 | Journal of Materials Science & Technology2003，19，2： | 0 |
