| 1 | Accelerated flow softening and dynamic transformation of Ti-6Al-4V alloy in two-phase region during hot deformation via coarsening αgrain显示文摘The flow softening is an important phenomenon during hot deformation of metallic materials.In the present work,a more evident flow softening of Ti-6 Al-4 V alloy when deformed in two-phase region was observed in coarser a grain sample,which was attributed to an accelerated dynamic transformation from harder α phase into β phases.Notably,full β microstructure was observed in coarse grain samples at strain of 1.2,while retained a phase was observed in fine a grain specimens.In the views of thermodynamics and crystallographic analysis,the in-depth mechanisms of dynamic transformation were further investigated. | Xiankun Ji Baoqi Guo Fulin Jiang Hong Yu Dingfa Fu Jie Teng Hui Zhang John J.Jonas | 2020 | Journal of Materials Science & Technology2020，36，1： | 5 |
| 2 | Differentiation of neuron-like cells from mouse parthenogenetic embryonic stem cells显示文摘Parthenogenetic embryonic stem cells have pluripotent differentiation potentials,akin to fertilized embryo-derived embryonic stem cells.The aim of this study was to compare the neuronal differentiation potential of parthenogenetic and fertilized embryo-derived embryonic stem cells.Before differentiation,karyotype analysis was performed,with normal karyotypes detected in both parthenogenetic and fertilized embryo-derived embryonic stem cells.Sex chromosomes were identified as XX.Immunocytochemistry and quantitative real-time PCR detected high expression of the pluripotent gene,Oct4,at both the mRNA and protein levels,indicating pluripotent differentiation potential of the two embryonic stem cell subtypes.Embryonic stem cells were induced with retinoic acid to form embryoid bodies,and then dispersed into single cells.Single cells were differentiated in N2 differentiation medium for 9 days.Immunocytochemistry showed parthenogenetic and fertilized embryo-derived embryonic stem cells both express the neuronal cell markers nestin,βIII-tubulin and myelin basic protein.Quantitative real-time PCR found expression of neurogenesis related genes(Sox-1,Nestin,GABA,Pax6,Zic5 and Pitx1) in both types of embryonic stem cells,and Oct4 expression was significantly decreased.Nestin and Pax6 expression in parthenogenetic embryonic stem cells was significantly higher than that in fertilized embryo-derived embryonic stem cells.Thus,our experimental findings indicate that parthenogenetic embryonic stem cells have stronger neuronal differentiation potential than fertilized embryo-derived embryonic stem cells. | Xingrong Yan Yanhong Yang Wei Liu Wenxin Geng Huichong Du Jihong Cui Xin Xie Jinlian Hua Shumin Yu Liwen Li Fulin Chen | 2013 | Neural Regeneration Research2013，8，4： | 4 |
| 3 | Influence of Ni interlayer on interfacial microstructure and mechanical properties of Ti-6Al-4V/AZ91D bimetals fabricated by a solid–liquid compound casting process显示文摘The solid–liquid compound casting of Mg-AZ91D and Ti-TC4 alloys was developed by using pure Ni electro-deposited coating.The pouring temperatures of 660℃,690℃,720℃and 750℃were chosen to investigated the effects of casting temperatures on microstructural evolution,properties,and fracture behaviors of Ni-coated TC4/AZ91D bimetals by the solid–liquid compound casting(SLCC).The scanning electron microscopy(SEM)and the energy dispersive spectroscopy(EDS)results showed that the interfacial zone mainly composed of nickel,Mg_(2)Ni and Mg-Al-Ni in the bimetals cast at 660℃.As the pouring temperature was increased to 750℃,the width of the interface zone,which mainly composed ofδ(Mg),Mg_(2)Ni,Mg-Al-Ni,Mg_(3)TiNi_(2) and Al_(3)Ni,gradually increased.The microhardness tests showed that the micro-hardness of the interface zone was smaller than that of TC4 substrate but larger than that of the cast AZ91D matrix.At the pouring temperature of 720℃,the Ni-coated TC4/AZ91D bimetals had the most typical homogeneous interface,which had granular Mg-Al-Ni ternary phase but no ribbon-like Al3Ni binary phase,and achieved the highest shear strength of 97.35MPa.Meanwhile,further fracture behavior analysis showed that most fracture failure of Ni-coated TC4/AZ91D bimetals occurred at the Mg_(2)Ni+δ(Mg)eutectic structure and Al_(3)Ni hard intermetallic. | Fulin Wen Jianhua Zhao Miaowang Yuan Jingfeng Wang Dengzhi Zheng Jinyong Zhang Ke He Jingjing Shangguan Yu Guo | 2021 | Journal of Magnesium and Alloys2021，9，4： | 3 |
| 4 | Modifying the Power and Performance of 2-Dimensional MoS_(2)Field Effect Transistors显示文摘Over the past 60 years,the semiconductor industry has been the core driver for the development of information technology,contributing to the birth of integrated circuits,Internet,artificial intelligence,and Internet of Things.Semiconductor technology has been evolving in structure and material with co-optimization of performance–power–area–cost until the state-of-the-art sub-5-nm node.Two-dimensional(2D)semiconductors are recognized by the industry and academia as a hopeful solution to break through the quantum confinement for the future technology nodes.In the recent 10 years,the key issues on 2D semiconductors regarding material,processing,and integration have been overcome in sequence,making 2D semiconductors already on the verge of application.In this paper,the evolution of transistors is reviewed by outlining the potential of 2D semiconductors as a technological option beyond the scaled metal oxide semiconductor field-effect transistors.We mainly focus on the optimization strategies of mobility(μ),equivalent oxide thickness(EOT),and contact resistance(RC),which enables high ON current(Ion)with reduced driving voltage(Vdd).Finally,we prospect the semiconductor technology roadmap by summarizing the technological development of 2D semiconductors over the past decade. | Fulin Zhuo Jie Wu Binhong Li Moyang Li Chee Leong Tan Zhongzhong Luo Huabin Sun Yong Xu Zhihao Yu | 2023 | Research2023，，3： | 2 |
| 5 | Effect of Konjac Food on Blood Glucose Level in Patients with Diabetes显示文摘Seventy-two type II diabetic subjects were given Konjac food for 65 days. The data analyzed by multiple F test indicate that the fasting blood glucose (FBG) and the 2-h postprandial blood glucose (PBG) on the 30th and the 65th days after the food was ingested were significantly reduced (P = 0.001, P < 0.001, respectively), as was the glycosylated hemoglobin level at the end of the trial (P < 0.05). The final FBG and PBG of the subjects with initial FBG-O >200 mg% decreased on the average by 51.8 and 84.6 mg%. respectively; those with FBG-0 150-200 mg% decreased by 24.1 and 68.7 mg%; and those with FBG-O < 150 mg% decreased by 4.8 and 21.4 mg%. No significant changes in blood lipid indexes were observed, except that the triglycer-ide values of subjects with hypertriglyceridemia (>200 mg%) significantly decreased by 118.7 mg%. It was concluded that Konjac food is very useful in the prevention and treatment of hyperglycemia. (C)1990 Academic Press.

| 8 | Direct numerical simulation of hypersonic boundary layer transition over a liftingbody model HyTRV显示文摘Direct numerical simulation(DNS)of transition over a hypersonic lifting body model HyTRV developed by China Aerodynamics Research and Development Center is performed.The free-stream parameters are:the free-stream Mach number is 6,the unit Reynolds number is 10000/mm,the free-stream temperature is 79 K,the angle of attack is 0,and the wall temperature is 300 K.Weak random blowing-and-suction perturbations in the leading range are used to trigger the transition.A high order finite-difference code OpenCFD developed by the authors is used for the simulation,and grid convergence test shows that the transition locations are grid-convergence.DNS results show that transition occurs in central area of the lower surface and the concaved region of the upper surface,and the transition regions are also the streamline convergence regions.The transition mechanisms in different regions are investigated by using the spectrum and POD analysis. | Han Qi Xinliang Li Changping Yu Fulin Tong | 2021 | Advances in Aerodynamics2021，3，1： | 1 |
| 9 | MoS_(2) nanoflowers coupled with ultrafine Ir nanoparticles for efficient acid overall water splitting reaction显示文摘Bi-functional electrocatalysts for acid overall water splitting reactions are crucial but still challenging to the development of proton exchange membrane water electrolysis.Herein,an efficient bi-functional catalyst of Ir/MoS_(2) nanoflowers(Ir/MoS_(2) NFs) catalyst was reported for acidic water electrolysis which can be constructed by coupling three-dimensionally interconnected MoS_(2) NFs with ultrafine Ir nanoparticles.A more suitable adsorption ability for the H* and *OOH intermediates was revealed,where the Ir sites were proposed as the main active center and MoS_(2) promoted the charge relocation to electronically modify the interfacial structure.The significant interfacial charge redistribution between the MoS_(2) NFs and the Ir active sites synergistically induced excellent catalytic activity and stability for the water electrolysis reaction.Specifically,the catalyst required overpotentials of 270 and 35 mV to reach a kinetic current density of 10 mA cm^(-2)for OER and HER,respectively,loading on the glass carbon electrode,with high catalytic kinetics,stability,and catalytic efficiency.A two-electrode system constructed by Ir/MoS_(2) NFs drove 10 mA cm^(-2)at a cell voltage of 1.55 V,about 70 mV lower than that of the commercial Pt/C||IrO_(2) system.In addition,partial surface oxidation of Ir nanoparticles to generate high-valent Ir species was also found significant to accelerate OER.The enhanced catalytic performance was attributed to the strong metal-support interaction in the Ir/MoS_(2) NFs catalyst system that changed the electronic structure of Ir metal and promoted the synergistic catalytic effect between Ir and MoS_(2) NFs.The work presented a novel platform of Ir-catalyst for proton exchange membrane water electrolysis. | Chunyan Wang Lice Yu Fulin Yang Ligang Feng | 2023 | Journal of Energy Chemistry2023，，12： | 0 |
| 10 | Bias Analysis in the Simulation of the Western North Pacific Tropical Cyclone Characteristics by Two High-Resolution Global Atmospheric Models显示文摘This study compares the atmosphere-only HighResMIP simulations from FGOALS-f3-H(FGOALS)and MRIAGCM3-2-S(MRI)with respect to tropical cyclone(TC)characteristics over the Western North Pacific(WNP)for the July-October months of 1985-2014.The focus is on investigating the role of the tropical easterly jet over the Western Pacific(WP_TEJ)in modulating the simulation biases in terms of their climatological distribution and interannual variability of WNP TC genesis frequency(TCGF)based on the analysis of the genesis potential index(GPI).Results show that the two models reasonably capture the main TC genesis location,the maximum center of frequency,and track density;however,their biases mainly lie in simulating the intense TCs and TCGF distributions.The MRI better simulates the windpressure relationship(WPR)but overestimates the proportion of super typhoons(SSTYs).At the same time,FGOALS underestimates the WPR and the proportion of SSTYs but better simulates the total WNP TC precipitation.In particular,FGOALS overestimates the TCGF in the northeastern WNP,which is strongly tied to an overestimated WP_TEJ and the enhanced vertical circulation to the north of its entrance region.In contrast,the MRI simulates a weaker WP_TEJ and vertical circulation,leading to a negative TCGF bias in most of the WNP.Both models exhibit comparable capability in simulating the interannual variability of WP_TEJ intensity,but the composite difference of large-scale atmospheric factors between strong and weak WP_TEJ years is overestimated,resulting in larger interannual anomalies of WNP TCGF,especially for FGOALS.Therefore,accurate simulations of the WP_TEJ and the associated oceanic and atmospheric factors are crucial to further improving WNP TC simulations for both models. | Qiyang LIU Fengxue QIAO Yongqiang YU Yiting ZHU Shuwen ZHAO Yujia LIU Fulin JIANG Xinyu HU | 2023 | Advances in Atmospheric Sciences2023，40，4： | 0 |
