| 1 | Structure and property of metal melt Ⅳ——Evolution of titanium melt residual bond structure and its effect on dynamic viscosity显示文摘Based on the concept of melt residual bonds, a calculating model quantitatively describing the evolution of the residual bond structure of titanium melt at the melting point or in a certain range above the melting point was established; i.e., both the size dS and the bond number n of the residual bond structure decrease monotonously with the increase of temperature. By mathematical deduction, a linear relationship between the residual bond structure size dS and the dynamic viscosity of Titanium melt was revealed, i.e., = 0.876 + 0.471·dS, which is of great significance to the investigation of the relationship between the melt microstructure and the macroscopic properties of metals with high melting temperature. | MI GuangBao CAO JingXia HUANG Xu CAO ChunXiao LIPeiJie HE LiangJu | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，8： | 3 |

| 6 | Micellar Catalysis:Visible-Light Mediated Imidazo[1,2-a]pyridine C—H Amination with N-Aminopyridinium Salt Accelerated by Surfactant in Water显示文摘A light-promoted metal-free protocol for the amination of imidazo[1,2-a]pyridines with N-aminopyridinium salt by the assistance of surfactants in water was reported,charactering mild and environmentally benign conditions,as well as great functional group tolerance.Micelles with negatively charged polar surface and hydrophobic core formed from sodium dodecyl sulfate serve as an ideal medium for visible-light mediated radical reaction of cationic pyridine salt and imidazo[1,2-a]pyridine in aqueous phase.The electrostatic interaction between positively charged N-aminopyridinium and negatively charged surface of micelles is of great significance in this method. | Zhonglie Yang Kun Cao Xiaoyan Peng Li Lin Danchen Fan Jun-Long Li Jingxia Wang Xiaobin Zhang Hezhong Jiang Jiahong Li | 2021 | Chinese Journal of Chemistry2021，39，12： | 0 |
| 7 | Inhibition of MALT1 paracaspase activity improves lesion recovery following spinal cord injury显示文摘Spinal cord injury(SCI) is a devastating traumatic injury that causes persistent, severe motor and sensory dysfunction. Immune responses are involved in functional recovery after SCI. Mucosa-associated lymphoid tissue lymphoma translocation 1(MALT1) has been shown to regulate the survival and differentiation of immune cells and to play a critical role in many diseases, but its function in lesion recovery after SCI remains unclear. In this paper, we generated KI(knock in) mice with a point mutation(C472 G) in the active center of MALT1 and found that the KI mice exhibited improved functional recovery after SCI.Fewer macrophages were recruited to the injury site in KI mice and these macrophages differentiated into anti-inflammatory macrophages. Moreover, macrophages from KI mice exhibited reduced phosphorylation of p65, which in turn resulted in decreased SOCS3 expression and increased pSTAT6 levels.Similar results were obtained upon inhibition of MALT1 paracaspase with the small molecule inhibitor‘‘MI-2' or the more specific inhibitor ‘‘MLT-827'. In patients with SCI, peripheral blood mononuclear cells(PBMC) displayed increased MALT1 paracaspase. Human macrophages showed reduced proinflammatory and increased anti-inflammatory characteristics following the inhibition of MALT1 paracaspase. These findings suggest that inhibition of MALT1 paracaspase activity in the clinic may improve lesion recovery in subjects with SCI. | Hua Zhang Guodong Sun Xiaowei Li Zhen Fu Chengbin Guo Guangchao Cao Baocheng Wang Qian Wang Shuxian Yang Dehai Li Xichun Xia Peng Li Jing Zhu Wei Zhou Liangyan Zheng Jingxia Li Lei Zhang Jianlei Hao Libing Zhou Frederic Bornancin Zhizhong Li Zhinan Yin Yunfei Gao | 2019 | Science Bulletin2019，64，16： | 0 |
| 8 | Research and development of the longitudinal feedback system digital signal processing electronics in BEPCII显示文摘Background The current strategy to achieve high luminosity for high energy physics experiments is to store huge currents distributed in many bunches in circular machines such as BEPCII,so the longitudinal coupled bunch instabilities of the beam are inevitable.Purpose Therefore,a longitudinal feedback system is needed to suppress longitudinal oscillation.Otherwise,the beam energy spread will increase;the luminosity and the beam lifetime will decrease under a certain beam current.Methods For filter design of the feedback system,the time domain least square fitting(TDLSF)method is compared to the selective wave filter method;digital signal processing electronics based on commercial board have been developed and tested on BEPCII.Results The final result shows that the self-developed longitudinal feedback system can suppress the longitudinal beam oscillation at 750 mA beam current and meet the requirements of BEPCII;the restrain depth to the sidebands reaches to 40.8 dB. | Di Yin Junhui Yue Huizhou Ma Jianshe Cao Shujun Wei Cunbiao Hao Yanfeng Sui Jun He Jingxia Zhao Zhi Liu | 2021 | Radiation Detection Technology and Methods2021，5，2： | 0 |
| 9 | Stoichiometric NbTiAl_3 (γ1 Phase) Alloy in Ti-Al-Nb Ternary System显示文摘The microstructure and phase constitution in stoichiometric NbTiAl3 (γ1 phase) alloy treated at 1000℃ were examined by metallography and X-ray diffraction. The alloy microstructure is mainly γ1 phase containing η second phase [(Ti,Nb)Al3] less than 1%. DTA analysis shows no phase transformation from room temperature to 1200℃. In the diffusion couple of NbTiAl3 with 7-TiAl compound, clear phase boundary and composition jump exist between γ1 and γ phase.These results further confirm the existence of γ1 single phase at 1000℃ in Ti-Al-Nb ternary system. | Jingxia CAO Jinjun DING and Shiming HAO (Dept. of Materials Science and Technology, Northeastern University Shenyang 110006, China)(To whom correspondence should be addressed)Guoliang CHEN (Dept. of Materials Science and Technology University of Science | 1996 | Journal of Materials Science & Technology1996，12，6： | 0 |
