| 1 | Microstructure and Oxidation Behaviors of Nano-particles Strengthened NiCoCrAlY Cladded Coatings on Superalloys显示文摘Nano-particles which can largely improve the microstructure and oxidation resistance of materials are often used as a strengthening component in metal matrix composites. However, few studies were reported on its application in the bond coat of duplex structure thermal barrier coating(TBC). Three kinds of NiCoCrAlY coatings strengthened by different nano-particles with the same addition (1%, mass fraction) were prepared by the laser cladding technique on Ni-based superalloy substrates, aiming to study the effects of the nano-particles on microstructure and oxidation resistance of NiCoCrAlY coatings (the bond coat of the duplex structure thermal barrier coatings). Scanning electron microscope (SEM), X-ray diffractometer(XRD) and thermogravimetry were employed to investigate their morphologies, phases and cyclic oxidation behaviors in atmosphere at 1 050℃, compared with the coating without nano-particles. With the addition of nano-particles, the growth pattern of the grains at the interface changed from epitaxial growth to non-epitaxial growth or part-epitaxial growth; slender dendrites were broken and cellularized; cracks and pores were restrained; and the oxidation weight-gain and the stripping resistance of the oxide scale were improved as well. Among the three kinds of nano-particles, the SiC nano-particles showed the most improvement on microstructure, while the CeO2 nano-particles were insufficient, but its effects on the oxidation resistance are the same as those of the SiC nano-particles. Based on the discussions of the influence mechanism, it is believed that CeO2 nano-particles would show better improvement than SiC nano-particles if the proper amount is added and the proper preparation technique of micro-nanometer composite powders is adopted, with the synergistic action of nanometer effect and reactive element effect. | WANG Hongyu ZUO Dunwen CHEN Xinfeng YU Shouxin GU Yuanzhi | 2010 | Chinese Journal of Mechanical Engineering2010，23，3： | 11 |

| 3 | Differentiation of fetal pancreatic stem cells into neuron-like and islet-like cells in vitro显示文摘Pancreatic stem cells were isolated and cultured from aborted human fetal pancreases of gestational age 14-20 weeks. They were seeded at a density of 1 × 104 in serum-free media for differentiation into neuron-like cells, expressing β-tubulin III and glial fibrillary acidic protein. These neuron-like cells displayed a synapse-like morphology and appeared to form a neuronal network. Pancreatic stem cells were also seeded at a density of 1 × 105 for differentiation into islet-like cells, expressing insulin and glucagon, with an islet-like morphology. These cells had glucose-stimulated secretion of human insulin and C-peptide. Results suggest that pancreatic stem cells can be differentiated into neuron-like and islet-like cells. | Xiufeng Hua Yanwei Wang Peiwen Lian Shouxin Zhang Jianyuan Li Haiyan Wang Shulin Chen Wei Gao | 2012 | Neural Regeneration Research2012，7，7： | 3 |
| 4 | Tensile and Isothermal Fatigue Behaviors of Mg-12Gd-3Y-0.5Zr Alloy at High Temperature显示文摘Tensile and isothermal fatigue tests were carried out on an as-rolled Mg-12Gd-3Y-0.5Zr alloy and its heat-treated counterpart at different temperatures. The experimental results show that the ultimate tensile strengths of two alloys decrease very slowly with increasing temperature up to 200?C. The ultimate tensile strength of heat-treated Mg-12Gd-3Y-0.5Zr is slight lower than that of as-rolled counterpart; however, the fatigue strength of heat-treated alloy is higher. The mechanism of fatigue failure was investigated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). It shows that cyclic slip combined with environmental effect may be the main crack initiation mechanism. | Xiaoming Yang Huajie Yang Fan Yang Shuming Yin Wei Wang Shouxin Li Qudong Wang | 2009 | Journal of Materials Science & Technology2009，25，6： | 2 |

| 8 | Carbon dots confined in 3D polymer network: Producing robust room temperature phosphorescence with tunable lifetimes显示文摘Room temperature phosphorescence(RTP) is important in both organic electronics and encryption. Despite rapid advances, a universal approach to robust and tunable RTP materials based on amorphous polymers remains a formidable challenge. Here, we present a strategy that uses three-dimensional(3 D)confinement of carbon dots in a polymer network to achieve ultra-long lifetime phosphorescence. The RTP of the as-obtained materials was not quenched in different polar organic solvents and the lifetime of the RTP was easily tuned by adjusting the amount of crosslinking or varying the drying temperature of the 3 D molecular network. As a demonstration of potential application, as-obtained RTP materials were successfully used to prepare RTP fibres for flexible textiles. As well as bringing to light a fundamental principle for the construction of polymer materials with RTP, we have endowed traditional carbon dots and polymers with fresh features that will expand potential applications. | Yingxiang Zhai Ping Wang Xinyue Zhang Shouxin Liu Jian Li Zhijun Chen Shujun Li | 2022 | Chinese Chemical Letters2022，33，2： | 1 |

| 10 | Nucleation of dislocations and twins in fcc nanocrystals: Dynamics of structural transformations显示文摘This paper reports on a molecular dynamics study of structural rearrangements in a copper nanocrystal during nucleation of plastic deformation under uniaxial tension. The study shows that the resulting nucleation of partial dislocations on the free surface and their glide occurs through local fcc→bcc→hcp transformations via consistent atomic displacements. We propose an atomic model for the generation of dislocations and twins based on local reversible fcc→bcc→fcc transformations, with the reverse one proceeding through an alternative system. The model gives an insight into possible causes and mechanisms of the generation of partial dislocations and mechanical twins in two and more adjacent planes of plastically deformed nanocrystals. The obtained data allow a better understanding of how plasticity is generated in nanostructured materials. | Aleksandr V.Korchuganov Aleksandr N.Tyumentsev Konstantin P.Zolnikov Igor Yu.Litovchenko Dmitrij S.Kryzhevich Elazar Gutmanas Shouxin Li Zhongguang Wang Sergey G.Psakhie | 2019 | Journal of Materials Science & Technology2019，35，1： | 1 |

| 12 | Enhancement of red emission assigned to inversion defects in ZnAl2O4:Cr3+ hollow spheres显示文摘ZnAl2O4:Cr3+hollow spheres composed of secondary nanoparticles with single spinel phase were fabricated using carbon templets.Monitoring the emission of 687 nm,two wide excitation bands attributed to the electrons of Cr3+transiting from 4A2g(4F)→4T1g(4F)and 4A2g(4F)→4T2g(4F)were observed.The broad excitation band at about 397 nm was asymmetric and consisted of two peaks,indicating that there was a trigonal distortion existing in the lattices.The intensity of all emitting peaks revealed sharp increasing trend with the sintering temperature increase,and the intensity of emission at 698 nm assigned to inversion defects was more intense than that of emission at 687 nm assigned to octahedral Cr3+ions in the undistorted spinel lattice.The samples with higher synthesized temperature revealed longer decay time,and the relative weightage of shorter decay time component decreased with the increase of sintering temperature,indicating that the surface defects decreased. | Dong Zhang Jingxin Chen Chunyu Du Bingjun Zhu Qingru Wang Qiang Shi Shouxin Cui Wenjun Wang | 2020 | Frontiers of Materials Science2020，14，1： | 0 |

| 15 | Edge localized modes suppression via edge E × B velocity shear induced by RF sheath of ion cyclotron resonance heating in EAST显示文摘The control of large edge localized modes(ELMs) is a critical issue for the successful operation of future burning plasma devices,such as the international thermonuclear experimental reactor(ITER) and China fusion engineering test reactor(CFETR). In this paper, we present a new active and effective means of ELM suppression using ion cyclotron resonant heating(ICRH) on the experimental advanced superconducting tokamak(EAST). We obtained the key role of the external E × B velocity shear near the pedestal top and the scrape-off-layer(SOL) induced by the RF sheath potential of ICRH in ELM suppression. The experimental results showed a positive correlation between the RF sheath and the E × B shear rate in SOL. BOUT++ simulations indicate that increased E × B velocity shear rates in the pedestal and SOL regions promote ELM suppression;thereby, supporting the experimental observations on EAST. These findings suggest a new simple approach to access the ELM suppressed regimes in plasma with low torque input as ITER baseline discharges. | XinJun Zhang Chu Zhou XiaoLan Zou TianYang Xia YanLong Li ChengMing Qin XianZu Gong Qing Zang MingHui Li Tao Zhang ShouXin Wang HaiQing Liu Guillaume Urbanczyk Adi Liu YanMing Duan YanPing Zhao JinPing Qian Robert Isaac Pinsker MinYou Ye BaoNian Wan | 2022 | Science China(Physics,Mechanics & Astronomy)2022，65，3： | 0 |
| 16 | Facile preparation and characterization of novel oleanane-type triterpene functionalized β-cyclodextrin conjugates显示文摘Oleanolic acid(OA) and echinocystic acid(EA), two naturally occurring pentacyclic oleanane triterpenes,are gaining increasing attention due to their promising pharmacological activities. Conjugation with amphiphilic α(β)-cyclodextrin(CD) via 'click chemistry' can improve their solubility and anti-HCV entry potency. In the present work,four water-soluble β-CD-pentacyclic triterpene conjugates were designed and synthesized, in which OA and EA was coupled to one of the primary hydroxyl groups of β-CD via ester and amide bonds. The structures of the conjugates were unambiguously determined by ~1H NMR, ^(13)C NMR and HRMS or MALDI-TOF-MS. All the conjugates showed lower hydrophobicity(AlogP) than their parent compounds and no significant cytotoxicity was found to HL-60, A549, Hela and Bel-7402 cells at concentrations up to 10 μmol/L. Further anti-HCV entry activity and mechanism studies are under way in our laboratory. | Pingxuan Jiao Shouxin Wang Shuobin Liang Man Li Qianqian Gao Dezhong Ji Yingying Chen Haiwei Li Fuxiang Ran Yongmin Zhang Lihe Zhang Demin Zhou Sulong Xiao | 2019 | Chinese Chemical Letters2019，30，3： | 0 |
| 17 | Numerical simulation of shear band localization in geotechnical materials based on a nonlocal plasticity model显示文摘A new nonlocal plasticity model,which is based on the integral-type nonlocal model and the cubic representative volumetric element(RVE),is proposed to simulate shear band localization in geotechnical materials such as soils and rocks.An algorithm is developed to solve the resulting nonlinear system of equations.In this algorithm,the nonlocal averaging of plastic strain over the RVE is evaluated using C0 elements instead of using C1 elements to solve the second-order gradient of plastic strains.To obtain the average plastic strain,a set of special elements,called the nonlocal elements,are constructed to approximate the RVE.The updating of average stresses of the local element is based on the nonlocal plastic strain of the corresponding nonlocal elements.Numerical examples show that meshindependent results can be achieved using the proposed model and the algorithm,and the thickness of the shear band is insensitive to the mesh refinement. | Shouxin WU Xingran WANG | 2011 | Journal of Modern Transportation2011，19，3： | 0 |
