| 1 | Effect of the simultaneous application of a high static magnetic field and a low alternating current on grain structure and grain boundary of pure aluminum显示文摘Effect of the simultaneous application of a high static magnetic field and a low alternating electric current on the solidification structure of pure aluminum has been investigated. Results show that the refinement of the solidification structure is enhanced by the electric current under a certain magnetic field. However,when the magnetic field intensity exceeds a certain value, the refinement is impaired under a certain electric current. The observation by electron backscattered diffraction(EBSD) shows the complex fields have led to the increase of the low angle boundaries with the refinement. Moreover, the application of the static gradient magnetic field is capable of modifying the distribution of the refined grains. The above results may be attributed to the formation of the cavities during the electromagnetic vibration process and the high magnetic field. | Chengshuai Li Shaodong Hu Zhongming Ren Yves Fautrelle Xi Li | 2018 | Journal of Materials Science & Technology2018，34，12： | 7 |
| 2 | Effect of transverse static magnetic field on radial microstructure of hypereutectic aluminum alloy during directional solidification显示文摘The effect of different scales thermoelectric magnetic convection(TEMC)on the radial solidification microstructure of hypereutectic Al alloy has been investigated under transverse static magnetic field during directional solidification,focusing on the formation of freckle.Our experimental and numerical simulation results indicate that the TEMC circulation at sample scale under transverse static magnetic field leads to the enrichment of solute Al on one side of the sample.The TEMC and the solute enrichment degree increase with the increase of magnetic field when the magnetic field increases to 0.5 T.The enrichment degree of solute elements under magnetic field is affected by temperature gradient and growth rate.The non-uniform distribution of solute Al in the radial direction of the sample results in the non-uniform distribution of primary dendrite arm spacing(PDAS).Moreover,the applied magnetic field can lead to freckle formation and its number increases with the increase of magnetic field.The change of freckle is consistent with the anisotropy TEMC caused by the anisotropy of primary dendrite or primary dendrite network under magnetic field.Finally,the mechanism of synergism effect of the anisotropy TEMC,the distribution of solute Al and the PDAS on freckle formation and evolution is studied during directional solidification under magnetic field. | Shaodong Hu Long Hou Kang Wang Zhongmiao Liao Wen Zhu Aihua Yi Wenfang Li Yves Fautrelle Xi Li | 2021 | Journal of Materials Science & Technology2021，，17： | 4 |

| 5 | Controlling and adjusting the concentration distribution during solidification process using static magnetic fields显示文摘As concentration distribution changes have important effects on material structures and properties,controlling the concentration distribution is essential to alloy performance.The aim of the present work is to control and adjust the concentration distribution by the static magnetic field.It is found that the magnetic field disperses grain boundary segregation and causes the uniform distribution of concentration.Further,by the three-dimensional computed tomography(3 D-CT) reconstruction,the flow distribution is seen and the effect mechanism of the magnetic field is revealed.The present work may clarify the ambiguous understanding on the effect of the static magnetic field on solidification process. | Pinfang Jiang Jiantao Wang Long Hou Yves Fautrelle Xi Li | 2020 | Journal of Materials Science & Technology2020，47，15： | 3 |

| 11 | 低剂量白细胞介素-2在11种自身免疫疾病中的免疫学和临床疗效:单中心开放临床试验显示文摘背景调节性T(Tregs)细胞可以预防自身免疫并控制炎症,在各种自身免疫性或自身炎症性疾病中的研究都表明Treg细胞不足。由于低剂量白细胞介素-2(low-dose interleukin-2,ld-IL2)能够扩增并激活Tregs细胞,因此ld-IL2具有广泛的治疗潜力。目的我们通过一项临床试验观察ld-IL2治疗11种自身免疫性疾病中1种的效果,旨在评估ld-IL2的治疗潜力并选择疾病,以用于进一步的临床开发。方法本研究为前瞻开放性Ⅰ~Ⅱa期临床观察,入选了46例轻中度患者,诊断分别为类风湿关节炎、强直性脊柱炎、系统性红斑狼疮、牛皮癣、白塞病、肉芽肿性多血管炎、大动脉炎、克罗恩病、溃疡性结肠炎、自身免疫性肝炎或硬化性胆管炎。所有患者都接受了ld-IL2(100万IU/天)5天,然后每两周注射一次,维持6个月。所有患者均接受了深入的免疫监测和临床评估。结果在任何疾病类型以及任何合并药物治疗的患者中,ld-IL2都显示出了良好的耐受性。通过经典的免疫表型分析和广泛的免疫表型分析发现所有患者的Tregs细胞均被特异性地扩增激活,而效应T细胞没有被活化,提示ld-IL2具有临床疗效的前景。结论本研究中所采用的IL-2剂量和治疗方案可以选择性地激活和扩增Tregs细胞,并且对于不同的疾病种类以及不同的合并用药都是安全的。这一临床疗效以及初步结果可以为ld-IL2在各种自身免疫和自身炎症性疾病中开展Ⅱ期临床试验观察疗效提供了依据。试验注册号NCT01988506. | Michelle Rosenzwajg Roberta Lorenzon Patrice Cacoub Hang Phuong Pham Fabien Pitoiset Karim El Soufi Claire RIbet Claude Bernard Selim Aractingi Beatrice Banneville Laurent Beaugerie Francis Berenbaum Julien Champey Olivier Chazouilleres Christophe Corpechot Bruno Fautrel Arsfene Mekinian Elodie Regnier David Saadoun Joe-Elie Salem Jeremie Sellam Philippe Seksik Anne Daguenel-Nguyen Valene Doppler Jeremie Mariau Eric Vicaut David Klatzmann 杨新蕾(译) 张卓莉(校) | 2019 | 英国医学杂志中文版2019，22，2： | 2 |
| 12 | Parametric instability of a liquid metal sessile drop under the action of low-frequency alternating magnetic fields显示文摘A 2-D mathematical model is developed in order to simulate a parametric electromagnetic instability oscillation process of a liquid metal droplet under the action of low frequency magnetic field. The Arbitrary Lagrangian-Eulerian (ALE) method and weak form constraint boundary condition are introduced in this model for implementation of the surface tension and electromagnetic force on liquid droplet free surface. The results of the numerical calculations indicate the appearance of various regimes of oscillation. It is found that according to the magnetic field frequency various types of oscillation modes may be found. The oscillation is originated from an instability phenomenon. The stability diagram of liquid metal droplet in the parameter space of magnetic frequency and magnetic flux density is determined numerically. The diagram is very similar to that found in the so-called parametric instability. | 雷作胜 郭加宏 FAUTRELLE Yves ERNST Roland ETAY Jacqueline 任忠鸣 | 2013 | Journal of Hydrodynamics2013，25，2： | 2 |

| 14 | Nucleation kinetics of paramagnetic and diamagnetic metal melts under a high magnetic field显示文摘The influence of a high magnetic field(HMF)on the nucleation kinetics of paramagnetic aluminum and diamagnetic zinc melts has been investigated by differential thermal analysis(DTA).It is found that the application of an HMF increases the undercooling of pure aluminum and pure zinc at the same heatingcooling rates.Moreover,the quantitative analysis of activation energy calculated from the DTA results using the Kissinger method manifests that the HMF reduces the activation energy of pure aluminum and pure zinc.Regardless of magnetism,the nucleation frequency under an HMF is higher than that without an HMF.Furthermore,the increase in undercooling under the HMF is mainly attributed to the increase of the contact angle,calculated by the functional relationship between the cooling rate and undercooling.This result is consistent with the increase of the calculated nucleation work for pure aluminum and pure zinc.Additionally,the increase in undercooling caused by the HMF is partly ascribed to the magnetic field-induced suppression of thermal convection in the undercooled melt. | Zhipeng Long Qiuyue Jiang Jiantao Wang Long Hou Xing Yu Yves Fautrelle Zhongming Ren Xi Li | 2021 | Journal of Materials Science & Technology2021，，14： | 2 |
