2Protonation induced high-T_c phases in iron-based superconductors evidenced by NMR and magnetization measurements显示文摘Chemical substitution during growth is a well-established method to manipulate electronic states of quantum materials, and leads to rich spectra of phase diagrams in cuprate and iron-based superconductors. Here we report a novel and generic strategy to achieve nonvolatile electron doping in series of(i.e.11 and 122 structures) Fe-based superconductors by ionic liquid gating induced protonation at room temperature. Accumulation of protons in bulk compounds induces superconductivity in the parent compounds, and enhances the Tclargely in some superconducting ones. Furthermore, the existence of proton in the lattice enables the first proton nuclear magnetic resonance(NMR) study to probe directly superconductivity. Using Fe S as a model system, our NMR study reveals an emergent high-Tcphase with no coherence peak which is hard to measure by NMR with other isotopes. This novel electric-fieldinduced proton evolution opens up an avenue for manipulation of competing electronic states(e.g.Mott insulators), and may provide an innovative way for a broad perspective of NMR measurements with greatly enhanced detecting resolution.Yi Cui Gehui Zhang Haobo Li Hai Lin Xiyu Zhu Hai-Hu Wen Guoqing Wang Jinzhao Sun Mingwei Ma Yuan Li Dongliang Gong Tao Xie Yanhong Gu Shiliang Lie Huiqian Luo Pu Yu Weiqiang Yu 2018Science Bulletin2018,63,1:7

5Implementation of an efficient segregated algorithm-IDEAL on 3D collocated grid system显示文摘The segregated algorithm-IDEAL (inner doubly-iterative efficient algorithm for linked-equations) is an efficient and stable algorithm. In this algorithm, there exist inner doubly-iterative processes for pres-sure equation, which almost completely overcome two approximations in SIMPLE algorithm. Thus the coupling between velocity and pressure is fully guaranteed, greatly enhancing the convergence rate and stability of iteration process. In this paper, implementation of the IDEAL algorithm on a 3D collo-cated grid system is conducted. The interface velocity is calculated by the modified momentum inter-polation method (MMIM), by which the converged result is independent of the under-relaxation factor. Finally, five three-dimensional incompressible fluid flow and heat transfer problems are provided to compare the convergence rate and robustness between the IDEAL and three other most widely-used algorithms (SIMPLER, SIMPLEC and PISO). By the comparison it can be concluded that the IDEAL al-gorithm is more robust and efficient than the three other algorithms.SUN DongLiang QU ZhiGuo HE YaLing Tao WenQuan 2009Chinese Science Bulletin2009,54,6:5
6Numerical study of flow pattern modulation in a vertical phase separation condenser tube显示文摘The passive phase separation concept was proposed to modulate flow patterns for heat transfer enhancement. By the flow pattern modulation, the gas tends to be near the wall and the liquid tends to be in the tube core. Experiment has been performed to verify the fresh idea and the flow pattern modulation mechanism was analyzed qualitatively. This paper focuses on the numerical simulation of the bubble dynamics for a single bubble in the vertical phase separation condenser tube to quantitatively explore the flow pattern mechanism, based on a multiscale grid system and the volume-of-fluid (VOF) method. It is found that: (1) the modulated liquid film thickness can be decreased by 70% compared to that in the bare tube region; (2) the modulated bubble traveling velocity can be doubled, causing the increased liquid velocity and velocity gradient in the annular region to weaken the fluid boundary layer; (3) the significantly increased bubble traveling velocity in the annular region promotes the mass and momentum exchange between the annular region and the core region, and yields the self-sustained pulsating flow in the core region. The above three factors are benefit for the performance improvement of the heat transfer facilities.SUN DongLiang XU JinLiang CHEN QiCheng CAO Zhen 2013Chinese Science Bulletin2013,58,13:4
7Tocilizumab in patients with moderate or severe COVID-19: a randomized, controlled, open-label, multicenter trial显示文摘Tocilizumab has been reported to attenuate the“cytokine storm”in COVID-19 patients.We attempted to verify the effectiveness and safety of tocilizumab therapy in COVID-19 and identify patients most likely to benefit from this treatment.We conducted a randomized,controlled,open-label multicenter trial among COVID-19 patients.The patients were randomly assigned in a 1:1 ratio to receive either tocilizumab in addition to standard care or standard care alone.The cure rate,changes of oxygen saturation and interference,and inflammation biomarkers were observed.Thirty-three patients were randomized to the tocilizumab group,and 32 patients to the control group.The cure rate in the tocilizumab group was higher than that in the control group,but the difference was not statistically significant(94.12%vs.87.10%,rate difference 95%CI−7.19%–21.23%,P=0.4133).The improvement in hypoxia for the tocilizumab group was higher from day 4 onward and statistically significant from day 12(P=0.0359).In moderate disease patients with bilateral pulmonary lesions,the hypoxia ameliorated earlier after tocilizumab treatment,and less patients(1/12,8.33%)needed an increase of inhaled oxygen concentration compared with the controls(4/6,66.67%;rate difference 95%CI−99.17%to−17.50%,P=0.0217).No severe adverse events occurred.More mild temporary adverse events were recorded in tocilizumab recipients(20/34,58.82%)than the controls(4/31,12.90%).Tocilizumab can improve hypoxia without unacceptable side effect profile and significant influences on the time virus load becomes negative.For patients with bilateral pulmonary lesions and elevated IL-6 levels,tocilizumab could be recommended to improve outcome.Dongsheng Wang Binqing Fu Zhen Peng Dongliang Yang Mingfeng Han Min Li Yun Yang Tianjun Yang Liangye Sun Wei Li Wei Shi Xin Yao Yan Ma Fei Xu Xiaojing Wang Jun Chen Daqing Xia Yubei Sun Lin Dong Jumei Wang Xiaoyu Zhu Min Zhang Yonggang Zhou Aijun Pan Xiaowen Hu Xiaodong Mei Haiming Wei Xiaoling Xu 2021Frontiers of Medicine2021,15,3:2
8Condensation heat transfer enhancement mechanism for vertical upflows by the phase separation concept at small gravity显示文摘In the field of aerospace, minimum and seal of equipments cause the increase in the thermal loading sharply. Due to the lack of driving force, the performance of conventional condenser deteriorates greatly under the small gravity environment, which leads to reduction in the service life of equipments. In this study, a passive condenser, developed on basis of the phase separation concept,is utilized to improve the performance of the condensation heat transfer under the small gravity environment. As a result of the limitation of experiments, the mechanisms of heat transfer enhancement of the phase separation condenser tube are revealed through numerical simulation based on the volume-of-fluid(VOF) method. The following conclusions could be obtained:(1) A novel phase distribution of ‘‘gas near the tube wall and liquid in the tube core'' is formed. The thin liquid film is indeed created after the flow pattern modulation by inserting mesh cylinder.(2)The condensation quantity for single bubble in the annular region increases about 16 times greater than that in the bare tube region in the case of Jl= 0.0574 m/s and Jg= 0.0229 m/s.(3) Gas volume fraction affects the parameters of liquid film thickness, bubble length and liquid bridge length. The increase in the gas volume fraction results in the decrease in the evaluation index from21.56 to 12.82. The evaluation index is defined as the ratio of the condensation quantities per unit tube length of the annular region and the bare tube region.Qicheng Chen Dongliang Sun 2015Science Bulletin2015,60,20:2
9The bubble leakage mechanism for vertical upflows by the phase separation concept显示文摘Recently,our research group proposed the phase separation condenser tube,in which a mesh cylinder was inserted to form the flow structure of‘‘gas near the tube wall and liquid in the tube core’’,significantly enhance the condensation heat transfer.But the bubble leakage towards the core region may worsen the heat transfer enhancement.In order to prevent the bubble leakage,the critical criterion was proposed based on the Young–Laplace equation,considering the inertia force,viscous force and pulsating flow.It was found that the critical criterion depends on the dimensionless parameter G*,the We number and a coefficient C.The numerical model was developed in terms of the volume of fluid method to predict the two-phase laminar flow in the phase separation condenser tube.The results show that the bubble leakage takes place at the bubble tip,which is agreed with the experimental observations.The critical curve distinguishing the non-bubble-breaking and bubble-breaking was obtained by comparing the bubble dynamics at different G*and We.The coefficient C was determined.The critical criterion for the bubble leakage is given as G We0:22We0:99349 G4:7 103 We0:00651t196:39We0:006514cosa DHW,providing the design and operation guidance for the phase separation condenser tube.Qicheng Chen Jinliang Xu Dongliang Sun 2014Chinese Science Bulletin2014,59,21:2
10Effects of Epstein-Barr virus infection on the development of multiple myeloma after liver transplantation显示文摘Reduced cellular immune function in patients after liver transplantation easily results in many types of viral infections,such as Epstein-Barr virus.Epstein-Barr virus is a γ-herpesvirus and is related to many malignant diseases,especially epithelial and lymph tumors.The abnormal interaction of cluster of differentiation 40 with cluster of differentiation 40 ligand and expression of cluster of differentiation 40 ligand are considered closely related to the development of myeloma cells.This study explored the influence and mechanism of Epstein-Barr virus infection on the phenotype and biological behavior of myeloma cells after liver transplantation.Flow cytometry was used to detect coexpression of cluster of differentiation 40 and cluster of differentiation 40 ligand in 10 samples of freshly isolated multiple myeloma cells.Cluster of differentiation 40 and cluster of differentiation 40 ligand were coexpressed in sample Nos.5,8,9,and 10,particularly in sample No.5.Western blot analysis was used to detect the expression of the Epstein-Barr virus antigens latent membrane protein 1 and Epstein-Barr virus nuclear antigen 2 in the multiple myeloma cell line RPMI 8226 infected with Epstein-Barr virus.The antigen expression indicated that Epstein-Barr virus can infect multiple myeloma virus cells in vitro.Reverse transcription-polymerase chain reaction revealed upregulated expression of cluster of differentiation 40 ligand on the infected RPMI 8226 cells,which may be involved in the anti-apoptosis activity of the infected cells.Confocal microscopy showed that pairs of molecules of cluster of differentiation 40,cluster of differentiation 40 ligand,and latent membrane protein 1 were colocalized on the surface of the infected cells.CXC chemokine receptor 4 was upregulated on the RPMI 8226 cells after Epstein-Barr virus infection.The migratory ability of the infected cells improved in the presence of the chemokine stromal cell-derived factor-1α.Anti-apoptosis and migration are known important biological characteristics of malignant cells.Our results indicate the involvement of Epstein-Barr virus in the origin and development of multiple myeloma.The risk of multiple myeloma increases when Epstein-Barr virus infects B cells in the germinal center,which may result in an anti-apoptosis effect of B cells and an improved ability to migrate from the germinal center to peripheral blood.ZHANG YeWei ZHAO HeWei HE Xia ZHENG SuWen WANG TaiHong YAN DongLiang SUN JingFeng LU Xiang WEN JianFei LAU Wan Yee 2012Science China(Life Sciences)2012,55,8:2
