| 1 | A Comparative Study on Hydrodynamic Performance of Double Deflector Rectangular Cambered Otter Board显示文摘In the present work,the hydrodynamic performance of the double deflector rectangular cambered otter board was studied using wind tunnel experiment,flume tank experiment and numerical simulation.Results showed that the otter board had a good hydrodynamic performance with the maximum lift-to-drag ratio(K_(MAX) = 3.70).The flow separation occurred when the angle of attack(AOA) was at 45?,which revealed that the double deflector structure of the otter board can delay the flow separation.Numerical simulation results showed a good agreement with experiment ones,and could predict the critical AOA,which showed that it can be used to study the hydrodynamic performance of the otter board with the advantage of flow visualization.However,the drag coefficient in flume tank was much higher than that in wind tunnel,which resulted in a lower lift-to-drag ratio.These may be due to different fluid media between flume tank and wind tunnel,which result in the big difference of the vortexes around the otter board.Given the otter boards are operated in water,it was suggested to apply both flume tank experiment and numerical simulation to study the hydrodynamic performance of otter board. | XU Qingchang FENG Chunlei HUANG Liuyi XU Jiqiang WANG Lei ZHANG Xun LIANG Zhenlin TANG Yanli ZHAO Fenfang WANG Xinxin | 2018 | Journal of Ocean University of China2018，17，5： | 5 |

| 4 | DSC analysis of Al_2O_3-SiO_2 short fiber reinforced Al-Cu-Mg alloy matrix composites显示文摘Al_2O_3-SiO_2 short fiber/Al-Cu-Mg matrix composites containing different Mg contents were fabricated using squeeze casting method.Differential scanning calorimeter(DSC) was used to investigate the reaction condition of the composites with different Mg contents.The microstructure of the composites was observed by transmission electron microscopy(TEM).The experimental results show that the Mg content added to the 2024Al matrix significantly affects interfacial condition between Al2O3-SiO2 short fiber and aluminum matrix.At the temperature above 538 ℃,Al2O3-SiO2 short fiber is prone to react with Mg and forms MgAl2O4 reaction product when Mg content added to aluminum matrix is above 1.0wt%. | XU Hongyu,MENG Qingchang,GENG Lin,and LI Aibin School of Materials Science and Engineering,Harbin Institute of Technology,Harbin 150001,China | 2007 | Rare Metals2007，26，S1： | 1 |
| 5 | IbNIEL-mediated degradation of IbNAC087 regulates jasmonic acid-dependent salt and drought tolerance in sweet potato显示文摘Sweet potato(Ipomoea batatas[L.]Lam.)is a crucial staple and bioenergy crop.Its abiotic stress tolerance holds significant importance in fully utilizing marginal lands.Transcriptional processes regulate abiotic stress responses,yet the molecular regulatory mechanisms in sweet potato remain unclear.In this study,a NAC(NAM,ATAF1/2,and CUC2)transcription factor,IbNAC087,was identified,which is commonly upregulated in salt-and drought-tolerant germplasms.Overexpression of IbNAC087 increased salt and drought tolerance by increasing jasmonic acid(JA)accumulation and activating reactive oxygen species(ROS)scavenging,whereas silencing this gene resulted in opposite phenotypes.JA-rich IbNAC087-OE(overexpression)plants exhibited more stomatal closure than wild-type(WT)and IbNAC087-Ri plants under NaCl,polyethylene glycol,and methyl jasmonate treatments.IbNAC087 functions as a nuclear transcriptional activator and directly activates the expression of the key JA biosynthesisrelated genes lipoxygenase(IbLOX)and allene oxide synthase(IbAOS).Moreover,IbNAC087 physically interacted with a RING-type E3 ubiquitin ligase NAC087-INTERACTING E3 LIGASE(IbNIEL),negatively regulating salt and drought tolerance in sweet potato.IbNIEL ubiquitinated IbNAC087 to promote 26S proteasome degradation,which weakened its activation on IbLOX and IbAOS.The findings provide insights into the mechanism underlying the IbNIEL-IbNAC087 module regulation of JA-dependent salt and drought response in sweet potato and provide candidate genes for improving abiotic stress tolerance in crops. | Xu Li Zhen Wang Sifan Sun Zhuoru Dai Jun Zhang Wenbin Wang Kui Peng Wenhao Geng Shuanghong Xia Qingchang Liu Hong Zhai Shaopei Gao Ning Zhao Feng Tian Huan Zhang Shaozhen He | 2024 | Journal of Integrative Plant Biology2024，66，2： | 0 |
| 6 | Harnessing wrinkling morphologies of graphene on soft substrates for mechanically programmable interfacial thermal conductance显示文摘Strain engineering has been leveraged to tune the thermal properties of materials by introducing stress and manipulating local atomic vibrations,which poses a detrimental threat to the mechanical integrity of materials and structures and limits the capability to regulate thermal transport.Here,we report that the interfacial thermal conductance of graphene on a soft substrate can be regulated by harnessing wrinkling and folding morphologies of graphene,which could be well controlled by managing the prestrain applied to the substrate.These obtained graphene structures are free of significant in-plane mechanical strain and only have infinitesimal distortion to the intrinsic thermal properties of graphene.The subsequent thermal transport studies with pumpprobe non-equilibrium molecular dynamics(MD)simulation show that the thermal conductance between graphene structures and the substrate is uniquely determined by the morphological features of graphene.The atomic density of interfacial interactions,energy dissipation,and temperature distribution are elucidated to understand the thermal transport across each graphene structure and substrate.We further demonstrate that the normalized thermal conductance decreases monotonically with the increase of the equivalent mechanical strain,showing the capability of mechanically programmable interfacial thermal conductance in a broad range of strains.Application demonstrations in search of on-demand thermal conductance are conducted by controlling the geometric morphologies of graphene.This study lays a foundation for regulating interfacial thermal conductance through mechanical loading-induced geometric deformation of materials on a soft substrate,potentially useful in the design of flexible and stretchable structures and devices with tunable thermal management performance. | Qingchang Liu Baoxing Xu | 2023 | Nano Research2023，16，7： | 0 |
