| 1 | Direct numerical simulation of impinging shock wave and turbulent boundary layer interaction over a wavy-wall显示文摘The interaction of an impinging oblique shock wave with an angle of 30°and a supersonic turbulent boundary layer at Ma_(∞)=2.9 and Re_(θ)=2400 over a wavy-wall is investigated through direct numerical simulation and compared with the interaction on a flat-plate under the same flow conditions.A sinusoidal wave with amplitude to wavelength ratio of 0.26 moves in the streamwise direction and is uniformly distributed across the spanwise direction.The influences of the wavy-wall on the interaction,including the characterization of the flow field,the skin-friction,pressure and the budget of turbulence kinetic energy,are systematically studied.The region of separation grows slightly and decomposes into four bubbles.Local peaks of skin-friction are observed at the rear part of the interaction region.The low-frequency shock motion can be seen in the wall pressure spectra.Analyses of the turbulence kinetic energy budget indicate that both diffusion and transport significantly increase near the crests,balanced by an amplified dissipation in the near-wall region.Proper orthogonal decomposition analyses show that the most energetic structures are associated with the separated shock and the shear layer over the bubbles.Only the bubbles in the first two troughs are dominated by a low-frequency enlargement or shrinkage. | Fulin TONG Dong SUN Xinliang LI | 2021 | Chinese Journal of Aeronautics2021，34，5： | 3 |
| 2 | 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 |

| 7 | UBA3 promotes the occurrence and metastasis of intrahepatic cholangiocarcinoma through MAPK signaling pathway显示文摘Intrahepatic cholangiocarcinoma(icC)accounts for approximately 15%of primary liver cancers,and the incidence rate has been increasing in recentyears.Surgical resection is the best treatment for IcC,but the 5-year survival rate is less than 30%.IcC signature genes are crucial for the early diagnosis of IcC,so it is especially important to identify signature genes.The aim of this study is to screen the signature genes of IcC and find the potential target for the treatment of ICC.We find that UBA3 is highly expressed in ICC,and knockdown of UBA3 inhibits ICC proliferation,invasion and migration.Mechanistic experiments show that UBA3 promotes IcC proliferation,invasion and mi-gration by affecting ANXA2 through the MAPK signaling pathway.UBA3 is a target of bufalin,and bufalin targeting UBA3 inhibits ICC development and progression through the MAPK signaling pathway.In conclusion,our study shows that bufalin inhibits IcC by targeting UBA3,which has emerged as a new biomarker and potential therapeutic target forIcc. | Huhu Zhang Jiahua Yang Qinghang Song Xiaoyan Ding Fulin Sun Lina Yang | 2024 | Acta Biochimica et Biophysica Sinica2024，56，2： | 0 |
| 8 | Hypersonic shock wave and turbulent boundary layer interaction in a sharp cone/flare model显示文摘A direct numerical simulation of hypersonic Shock wave and Turbulent Boundary Layer Interaction(STBLI)at Mach 6.0 on a sharp 7.half-angle circular cone/flare configuration at zero angle of attack is performed.The flare angle is 34.and the momentum thickness Reynolds number based on the incoming turbulent boundary layer on the sharp circular cone is Re θ=2506.It is found that the mean flow is separated and the separation bubble occurring near the corner exhibits unsteadiness.The Reynolds analogy factor changes dramatically across the interaction,and varies between 1.06 and 1.27 in the downstream region,while the QP85 scaling factor has a nearly constant value of 0.5 across the interaction.The evolution of the reattached boundary layer is characterized in terms of the mean profiles,the Reynolds stress components,the anisotropy tensor and the turbulence kinetic energy.It is argued that the recovery is incomplete and the near-wall asymptotic behavior does not occur for the hypersonic interaction.In addition,mean skin friction decomposition in an axisymmetric turbulent boundary layer is carried out for the first time.Downstream of the interaction,the contributions of transverse curvature and body divergence are negligible,whereas the positive contribution associated with the turbulence kinetic energy production and the negative spatial-growth contribution are dominant.Based on scale decomposition,the positive contribution is further divided into terms with different spanwise length scales.The negative contribution is analyzed by comparing the convective term,the streamwise-heterogeneity term and the pressure gradient term. | Fulin TONG Junyi DUAN Jiang LAI Dong SUN Xianxu YUAN | 2023 | Chinese Journal of Aeronautics2023，36，3： | 0 |
| 9 | Single-cell manipulation by two-dimensional micropatterning显示文摘Cells are highly sensitive to their geometrical and mechanical microenvironment that directly regulate cell shape,cytoskeleton and organelle,as well as the nucleus morphology and genetic expression.The emerging two-dimensional micropatterning techniques offer powerful tools to construct controllable and well-organized microenvironment for single-cell level investigations with qualitative analysis,cellular standardization,and in vivo environment mimicking.Here,we provide an overview of the basic principle and characteristics of the two most widely-used micropatterning techniques,including photolithographic micropatterning and soft lithography micropatterning.Moreover,we summarize the application of micropatterning technique in controlling cytoskeleton,cell migration,nucleus and gene expression,as well as intercellular communication. | Xuehe Ma Haimei Zhang Shiyu Deng Qiushuo Sun Qingsong Hu Yuhang Pan Fen Hu Imshik Lee Fulin Xing Leiting Pan | 2024 | Journal of Innovative Optical Health Sciences2024，17，1： | 0 |

| 11 | Substituent engineering in g-C_(3)N_(4)/COF heterojunctions for rapid charge separation and high photo-redox activity显示文摘The heterojunction composed of covalent organic frameworks(COFs)with adjustable structure and other photocatalysts has great potential in the field of photocatalysis.However,effectively enhancing the photocatalytic performance of organic heterojunctions by designing the structure of COFs has not been explored.Herein,TPB-TP-COFs fabricated from 1,3,5-tris(4-amino-phenyl)benzene(TPB)and terephthalaldehyde(TP)with different substituents(−H,−OH,−OCH_(3),−Br and−F groups),were applied to construct g-C_(3)N_(4)/COFs.The performance improvement of the heterojunction could be affected by substituents,and only−OCH_(3) groups can significantly improve both the photocatalytic phenol oxidation and Cr(Ⅵ)reduction.DFT calculation demonstrated that the substituents will affect the electron cloud distribution of CBM,and the location of CBM in the TPB segment is beneficial for the charge transport between TPB-TP-OCH_(3) and g-C_(3)N_(4).The enhanced charge transfer from g-C_(3)N_(4) to TPB segment and the improved light absorption of TPB-TP-OCH_(3) jointly optimize the photocatalytic redox capacity of g-C_(3)N_(4)/TPB-TP-OCH_(3).On the basis of this study,regulating the electronic effects of semiconductors played a vital role in improving photocatalytic performance in organic heterojunctions. | Jiayun Guo Dongge Ma Fulin Sun Guilin Zhuang Qi Wang Abdullah M.Al-Enizi Ayman Nafady Shengqian Ma | 2022 | Science China Chemistry2022，65，9： | 0 |
