| 1 | High expression of ACE2 receptor of 2019-nCoV on the epithelial cells of oral mucosa显示文摘It has been reported that ACE2 is the main host cell receptor of 2019-nCoV and plays a crucial role in the entry of virus into the cell to cause the final infection. To investigate the potential route of 2019-n Cov infection on the mucosa of oral cavity, bulk RNA-seq profiles from two public databases including The Cancer Genome Atlas(TCGA) and Functional Annotation of The Mammalian Genome Cap Analysis of Gene Expression(FANTOM5 CAGE) dataset were collected. RNA-seq profiling data of 13 organ types with para-carcinoma normal tissues from TCGA and 14 organ types with normal tissues from FANTOM5 CAGE were analyzed in order to explore and validate the expression of ACE2 on the mucosa of oral cavity. Further, single-cell transcriptomes from an independent data generated in-house were used to identify and confirm the ACE2-expressing cell composition and proportion in oral cavity. The results demonstrated that the ACE2 expressed on the mucosa of oral cavity. Interestingly, this receptor was highly enriched in epithelial cells of tongue. Preliminarily, those findings have explained the basic mechanism that the oral cavity is a potentially high risk for 2019-nCoV infectious susceptibility and provided a piece of evidence for the future prevention strategy in dental clinical practice as well as daily life. | Hao Xu Liang Zhong Jiaxin Deng Jiakuan Peng Hongxia Dan Xin Zeng Taiwen Li Qianming Chen | 2020 | International Journal of Oral Science2020，12，1： | 69 |
| 2 | Effect of cooling rates on dendrite spacings of directionally solidified DZ125 alloy under high thermal gradient显示文摘The dendrite morphologies and spacings of directionally solidified DZ125 superalloy were investigated under high thermal gradient about 500 K/cm. The results reveal that, with increasing cooling rate, both the spacings of primary and secondary dendrite arms decrease, and the dendrite morphologies transit from coarse to superfine dendrite. The secondary dendrite arms trend to be refined and be well developed, and the tertiary dendrite will occur. The predictions of the Kurz/Fisher model and the Hunt/Lu model accord basically with the experimental data for primary dendrite arm spacing. The regression equation of the primary dendrite arm spacings λ1 and the cooling rate Vc is λ1=0.013Vc-0.32. The regression equation of the secondary dendrite arm spacing λ2 and the cooling rate Vc is λ2=0.00258Vc-0.31, which gives good agreement with the Feurer/Wunderlin model. | ZHANG Weiguo LIU Lin ZHAO Xinbao HUANG Taiwen YU Zhuhuan QU Min FU Hengzhi | 2009 | Rare Metals2009，28，6： | 11 |

| 4 | Relay-intercropping soybean with maize maintains soil fertility and increases nitrogen recovery efficiency by reducing nitrogen input显示文摘Optimized nitrogen(N)management can increase N-use efficiency in intercropping systems.Legume-nonlegume intercropping systems can reduce N input by exploiting biological N fixation by legumes.Measurement of N utilization can help in dissecting the mechanisms underlying N uptake and utilization in legume-nonlegume intercropping systems.An experiment was performed with three planting patterns:monoculture maize(MM),monoculture soybean(SS),and maize-soybean relay intercropping(IMS),and three N application levels:zero N(NN),reduced N(RN),and conventional N(CN)to investigate crop N uptake and utilization characteristics.N recovery efficiency and 15N recovery rate of crops were higher under RN than under CN,and those under RN were higher under intercropping than under the corresponding monocultures.Compared with MM,IMS showed a lower soil N-dependent rate(SNDR)in 2012.However,the SNDR of MM rapidly declined from 86.8%in 2012 to 49.4%in 2014,whereas that of IMS declined slowly from 75.4%in 2012 to 69.4%in 2014.The interspecific N competition rate(NCRms)was higher under RN than under CN,and increased yearly.Soybean nodule dry weight and nitrogenase activities were respectively 34.2%and 12.5%higher under intercropping than in monoculture at the beginning seed stage.The amount(Ndfa)and ratio(%Ndfa)of soybean N2 fixation were significantly greater under IS than under SS.In conclusion,N fertilizer was more efficiently used under RN than under CN;in particular,the relay intercropping system promoted N fertilizer utilization in comparison with the corresponding monocultures.An intercropping system helps to maintain soil fertility because interspecific N competition promotes biological N fixation by soybean by reducing N input.Thus,a maize-soybean relay intercropping system with reduced N application is sustainable and environmentally friendly. | Qing Du Li Zhou Ping Chen Xiaoming Liu Chun Song Feng Yang Xiaochun Wang Weiguo Liu Xin Sun Junbo Du Jiang Liu Kai Shu Wenyu Yang Taiwen Yong | 2020 | The Crop Journal2020，8，1： | 7 |
| 5 | Far-red light: A regulator of plant morphology and photosynthetic capacity显示文摘Plant photosynthetic capacity directly determines crop yield. Light quality regulates photosynthetic capacity. This review discusses plant responses to far-red light from the phenotypic to the molecular level, focusing specifically on the improvement of photosynthetic capacity by adjustment of photosynthetic electron transport and the path of light energy. Far-red light can also regulate leaf angle and increase plant height and leaf area, via expression of associated genes, to capture more light energy.Thus, far-red light regulates plant morphology and photosynthetic capacity. Identifying the mechanism of this regulation may lead to increased crop yields. | Tingting Tan Shenglan Li Yuanfang Fan Zhonglin Wang Muhammad Ali Raza Iram Shafiq Beibei Wang Xiaoling Wu Taiwen Yong Xiaochun Wang Yushan Wu Feng Yang Wenyu Yang | 2022 | The Crop Journal2022，10，2： | 4 |
| 6 | Influence of directional solidification variables on primary dendrite arm spacing of Ni-based superalloy DZ125显示文摘The primary dendrite morphology and spacing of DZ125 superalloy have been observed during directional solidification under high thermal gradient about 500 K/cm.The results reveal that the primary dendrite arm spacing decreases from 94μm to 35.8μm with the increase of directional solidification cooling rate from 2.525 K/s to 36.4 K/s.The regression equation of the primary dendrite arm spacingsλ 1 versus cooling rate is λ 1 =0.013(GV)-0.32.The predictions of Kurz/Fisher model and Hunt/Lu model accord reasonably well with the experimental data.The influence of directional solidi fication rate under variable thermal gradient on the primary dendrite arm spacing has also been investigated. | Zhang Weiguo Liu Lin Huang Taiwen Zhao Xinbao Qu Min Yu Zhuhuan Fu Hengzhi | 2009 | China Foundry2009，6，4： | 3 |
| 7 | Preparation of Inoculants Used in Superalloy and Analysis of the Atomic Matching Models显示文摘The mechanisms of grain refinement were investigated on two kinds of grain refiners used in Ni—Fe based superalloys and complete atomic matching modes were constructed in this study.It is found that there are at least three matching crystal planes having the small lattice disregistry between the refiner and the nucleated phase,which can lead to grain refinement of y matrix.The results indicate that the(0001),(01—10) planes of CrFeNb have a fine crystallographic matching relationship with the(111),(110) planes ofγmatrix.The disregistry of(0001)_(CrFeNb)//(111)_γ,(0110)_(CrFeNb)//(111)_γand(0110)_(CrFeNb)//(110)_γis 3.34%,6.60%and 5.90%, respectively.The(0001),(0110) planes of Co_3FeNb_2 and(111),(110) planes ofγmatrix also have this relationship.The disregistry of(0001)_(Co3FeNb2)//(111)_γ,(0001)_(Co3FeNb2)//(110)_γ,(0110)_(Co3FeNb2)//(111)_γand (0110)_(Co3FeNb2)//(110)_γis 4.45%,9.35%,8.38%and 6.12%,respectively. | Fu Wang Jun Zhang Taiwen Huang Lin Liu Hengzhi Fu | 2013 | Journal of Materials Science & Technology2013，29，4： | 3 |
| 8 | Coarsening kinetics of γ' precipitates in a Re-containing Ni-based single crystal superalloy during long-term aging显示文摘The morphological evolution and coarsening kinetics ofγ'precipitates in a Re-containing Ni-based single crystal superalloy were investigated during isothermal aging at 900,950 and 1000℃.After heat treatment,well-defined cuboidalγ'precipitates with low misfit was obtained within the experimental alloy.Then coarsening rate constants and particle size distribution(PSD)ofγ'phases were calculated and specified based on the measured precipitate sizes for va rying periods of aging times from 100 to 2000 h.After aging for 2000 h,γ'precipitates maintained cubical shape at 900℃,while exhibited sphere at 950 and 1000℃.Coarsening models based on diffusion-controlled process with a functional relationship of r^(3) vs.t(classic Lifshitz-Slyozov-Wagner coarsening model)and interface-controlled model with a function of r^(2) vs.t(trans-interface diffusion-controlled coarsening model)were investigated to fit between the experimental results and theoretical analysis.It was found that Re as the slowest diffusing solute in the alloy constituted the rate-limited step for coarsening based on LSW model,while the process limiting coarsening as governed by an interface diffusion process could possibly be related to the Al diffusion through theγ/γ'interface.The PSDs and coarsening exponent were discussed by comparing the experimental data with predictions of LSW and TIDC models.Finally,coarsening mechanism could be divided into four regimes:(i)coarsening by diffusion-controlled;(ii)coarsening by diffusion and interface cocontrolled;(iii)coarsening by interface-controlled;(iv)coarsening by interface-controlled accompanied withγ'coalescence. | Jiachen Zhang Lin Liu Taiwen Huang Jia Chen Kaili Cao Xinxin Liu Jun Zhang Hengzhi Fu | 2021 | Journal of Materials Science & Technology2021，，3： | 2 |

| 10 | Stress dependence of the creep behaviors and mechanisms of a third-generation Ni-based single crystal superalloy显示文摘Elevated temperature creep behaviors at 1100℃ over a wide stress regime of 120-174 MPa of a thirdgeneration Ni-based single crystal superalloy were studied. With a reduced stress from 174 to 120 MPa, the creep life increased by a factor of 10.5, from 87 h to 907 h, presenting a strong stress dependence. A splitting phenomenon of the close-(about 100 nm) and sparse-(above 120 nm) spaced dislocation networks became more obvious with increasing stress. Simultaneously, ao<010> superdislocations with low mobil让ies were frequently observed under a lower stress to pass through γ precipitates by a combined slip and climb of two ao<110> superpartials or pure climb. However, ao<110> superdislocations with higher mobility were widely found under a higher stress, which directly sheared into y precipitates. Based on the calculated critical resolved shear stresses for various creep mechanisms, the favorable creep mechanism was systematically analyzed. Furthermore, combined with the microstructural evolutions during different creep stages, the dominant creep mechanism changed from the dislocation climbing to Orowan looping and precipitates shearing under a stress regime of 137-174MPa, while the dislocation dim bing mechanism was operative throughout the whole creep stage un der a stress of 120 MPa, resulting a superior creep performanee. | Quanzhao Yue Lin Liu Wenchao Yang Chuang He Dejian Sun Taiwen Huang Jun Zhang Hengzhi Fu | 2019 | Journal of Materials Science & Technology2019，35，5： | 2 |
| 11 | Formation mechanisms and control method for stray grains at melt-back region of Ni-based single crystal seed显示文摘An experimental study together with numerical simulation was conducted to investigate the formation mechanisms and control methods for stray grains at melt-back of seed in this paper.The numerical simulation results showed that the convex solid/liquid(S/L)interface changed very slowly into a concave interface during the initial solidification stage and the undercooling was slightly affected by the S/L curvature change.The formation of stray grains below melt-back interface at seed perimeter could be suppressed with the decrease of clearance between the seed and mold.However when the clearance was further decreased to 0,an orientation deviation layer formed originated from the deformation of un-melted seed caused by different expend coefficient between the seed and mold.The nucleation of stray grains above the melt-back interface at the seed perimeter could be suppressed using the mold with small surface roughness.The isolated un-melted dendrite stem at semi-solid mushy of the seed with the large original primary dendrite spacing transfer to complex network structure,suppressing the formation of the stray grains,when the primary dendrite spacing of seed decreased or the seed underwent solution heat treatment.Then,the formation mechanisms of the stray grains at the melt-back region are discussed based on above results,and a method is proposed to suppress the formation of the stray grains for preparing single crystal components by re-used seed . | Songsong Hu Wenchao Yang Zhuoran Li Hanyuan Xu Taiwen Huang Jun Zhang Haijun Su Lin Liu | 2021 | Progress in Natural Science:Materials International2021，31，4： | 2 |
| 12 | Tailoring Microstructure and Microsegregation in a Directionally Solidified Ni-Based SX Superalloy by a Weak Transverse Static Magnetic Field显示文摘A weak transverse static magnetic field(WTSMF,0–0.5 T)is applied to the directional solidification process of a DD3 Ni-based SX superalloy,aiming to tailor the microstructure and microsegregation of alloys.The mechanisms of microstructural refinement and microsegregation distribution caused by a WTSMF during directional solidification are discussed.It is shown that the primary dendrite arm spacing is rapidly reduced from 181 to 143μm,and the average size ofγ′phase is significantly refined from 0.85 to 0.25μm as the magnetic field increases from 0 to 0.5 T.At the same time,the volumefractions ofγ/γ′eutectic and the segregation coefficient are also gradually decreased.The 3D numerical simulations of the multiscale convection in liquid phase show that the modifications of the microstructure and microsegregation in DD3 are mainly attributed to the enhanced liquid flow caused by thermoelectric magnetic convection(TEMC)at dendrite/sample scale under the WTSMF.The maximum of the TEMC increases with increasing the magnetic field intensity.This work paves a simple way to optimize the microstructure and microsegregation in directionally solidified Ni-based SX superalloys without changing the processing parameters and composition. | Yong Zhao Haijun Su Guangrao Fan Chenglin Liu Taiwen Huang Wenchao Yang Jun Zhang Lin Liu Hengzhi Fu | 2022 | Acta Metallurgica Sinica(English Letters)2022，35，7： | 1 |
