| 1 | Microstructural Evolution and Mechanical Properties of Inconel 625 Alloy during Pulsed Plasma Arc Deposition Process显示文摘Pulsed plasma arc deposition(PPAD),which combines pulsed plasma cladding with rapid prototyping,is a promising technology for manufacturing near net shape components due to its superiority in cost and convenience of processing.In the present research,PPAD was successfully used to fabricate the Ni-based superalloy Inconel 625 components.The microstructures and mechanical properties of deposits were investigated by scanning electron microscopy(SEM),optical microscopy(OM),transmission electron microscopy(TEM) with energy dispersive spectrometer(EDS),microhardness and tensile testers.It was found that the as-deposited structure exhibited homogenous columnar dendrite structure,which grew epitaxially along the deposition direction.Moreover,some intermetallic phases such as Laves phase,minor MC(NbC, TiC) carbides and needle-likeδ-Ni_3Nb were observed in y-Ni matrix.Precipitation mechanism and distribution characteristics of these intermetallic phases in the as-deposited 625 alloy sample were analyzed.In order to evaluate the mechanical properties of the deposits,microhardness was measured at various location (including transverse plane and longitudinal plane).The results revealed hardness was in the range of 260—285 HV_(0.2).In particular,microhardness at the interface region between two adjacent deposited layers was slightly higher than that at other regions due to highly refined structure and the disperse distribution of Laves particles.Finally,the influence of precipitation phases and fabrication strategies on the tensile properties of the as-deposited samples was investigated.The failure modes of the tensile specimens were analyzed with fractography. | Fujia Xu Yaohui Lv Yuxin Liu Fengyuan Shu Peng He Binshi Xu | 2013 | Journal of Materials Science & Technology2013，29，5： | 33 |

| 3 | Remanufacturing Shaping System Based on Pulsed Plasma Arc Welding显示文摘Based on the pulsed plasma arc welding(PPAW),a rapid remanufacturing shaping system,including a structured light scanning reverse engineering(RE)system,a robot system and a PPAW source system have been developed.The new rapid remanufacturing shaping system can rapidly and accurately repair the worn parts with different damaged degrees and thus extend their life cycle.In the present paper,the whole process of repairing worn parts is described.Firstly,the scanning model of a worn part is obtained by using RE system based on reconstructing approach.Compared with standard CAD model in the undamaged setting,the surface profile and the extent of damage area are obtained.Secondly,the weld repair path is designed by slicing the point cloud model of damage area.This path consists of multilayer parallel lines that produce parallel overlapped weld beads which cover the damaged area.By off-line programming techniques,the robot executable program as document format is transmitted to the robot controller for repairing worn parts.Finally,the weld repair experiments on worn steel plane plate and damaged column are performed to evaluate the remanufacturing system. | Xu Fujia Xu Binshi Lv Yaohui Xiang, Wu Peng, He Liu Yuxin | 2012 | 稀有金属材料与工程2012，41，S1： | 3 |
| 4 | Ion association tailoring SEI composition for Li metal anode protection显示文摘Electrolyte additives play an important role in suppressing lithium dendrites through tailoring the composition/property of the SEI,however lacking of additives can achieve high performances both in ether and carbonate electrolytes hinders further enhancement of the high voltage lithium^-metal batteries.Here,lithium perchlorate(LiClO4)has been presented as an excellent additive to meet the above requirements.An optimized chemical composition of SEI can be achieved through the formation of ionic association.Our results indicate that the LiClO4 behaves like a catalyst,which promotes LiTFSI to form a better SEI to inhibit further reaction.Superior coulombic efficiencies and cycling performances were obtained both in ether and carbonate electrolytes.This study paves a new pathway for designing bi-soluble additives for safe lithium metal batteries. | Yitao He Yaohui Zhang Peng Yu Fei Ding Xifei Li Zhihong Wang Zhe Lv Xianjie Wang Zhiguo Liu Xiqiang Huang | 2020 | Journal of Energy Chemistry2020，29，6： | 2 |
| 5 | Distribution and origin of high magnetic anomalies at Luobusa Ophiolite in Southern Tibet显示文摘The Luobusa Ophiolite,Southern Tibet,lies in the eastern portion of Indus–Yarlung Zangbo suture zone that separates Eurasia from the Indian continent.An aeromagnetic reconnaissance survey has revealed an EWtrending Yarlung Zangbo River aeromagnetic anomaly zone,and it is considered to be caused mainly by the Indus–Yarlung Zangbo Ophiolite.The Luobusa Ophiolite reflects the eastern portion of the Yarlung Zangbo River aeromagnetic anomaly zone.Conventionally,the ultramafic rock in the Luobusa Ophiolite is considered as the origin of the high magnetic anomalies.However,results from the surface magnetic survey and the magnetic susceptibility measurements from drill cores indicate that the high magnetic anomalies are distributed inhomogeneously in the Luobusa Ophiolite.In some cases,the susceptibility exhibits more than 30 times difference between two sides of the same sample.A fact emerged that the susceptibility of dunite with serpentinization is higher than that of fresh dunite,harzburgite and chromite when we analyzed the measurement results.In order to understand the origin of the high magnetic anomalies,we measured the density and susceptibility of 17 samples,microscopic and electron probe analyses have been performed as well.The result indicates the presence of dunite with serpentinization containing an abundant of micro-fissures filled with magnetite.Olivine has a susceptibility of about 2.7–351(910-5SI),pyroxene about 16–320,and chromite about200–800.All these units feature relatively low susceptibility in ultramafic rock,and only the magnetite is characterized by a high susceptibility of about 200,000(910-5SI).Based on these observations,we conclude that the precipitation of magnetite in the process of serpentinization of the olivine caused by the geological process in the Luobusa Ophiolite is the origin of high magnetic anomalies. | Lanfang He Xiumian Hu Yabing Zha Ligui Xu Yaohui Wang | 2014 | Chinese Science Bulletin2014，59，23： | 2 |

| 7 | Experimental Study on the Improvement of Yaw Stability by Coordination Control between the Caudal Fin and Anal Fin显示文摘Due to the unique locomotion,the head-shaking problem of biomimetic robotic fish inevitably occurs during rectilinear locomotion,which strongly hinders its practical applications.In this paper,we experimentally study this problem by proposing the method of coordination control between the caudal fin and anal fin.First,an untethered biomimetic robotic fish,equipped with an anal fin,a caudal fin and two pectoral fins,is developed as the experimental platform.Second,a Central Pattern Generator(CPG)-based controller is used to coordinate the motions of the anal fin and caudal fin.Third,extensive experiments are conducted to explore different combinations of the flapping frequencies,the flapping amplitudes,and the phase differences between the anal fin and caudal fin.Notably,through proper control of the anal fin,the amplitude of the yaw motion can be as small as 4.32°,which sees a 65%improvement compared to the scenario without anal fin,and a 57%improvement compared to that with a stationary anal fin.This paper provides a novel way to alleviate the head-shaking problem for biomimetic robotic fish,and first test this method on an untethered,freely swimming robotic platform,which can shed light on the development of underwater robotics. | Jiang Ding Changzhen Zheng Chaocheng Song Qiyang Zuo Yaohui Xu Bingbing Dong Jiaxu Cui Kai He Fengran Xie | 2022 | Journal of Bionic Engineering2022，19，5： | 1 |
| 8 | The synthesis of PROTAC molecule and new target KAT6A identification of CDK9 inhibitor i CDK9显示文摘Cyclin-dependent kinases(CDKs) have become potential targets for treating various diseases, especially cancer. Compound i CDK9 is an excellent and selective CDK9 inhibitor, but its major limitation is the potential toxicity and poor understanding of the underlying mechanism. The PROTAC(proteolysis targeting chimera) degraders of bioactive molecules can significantly induce in vitro and in vivo degradation of their target protein with high selectivity and effectively reduce the dose-limiting toxicity of small molecule drugs. Therefore, we designed and synthesized the bifunctional PROTAC molecules of i CDK9, being used for identifying its previously unknown target and revealing the underlying pharmacological mechanism.The PROTAC bifunctional molecule CD-5 could selectively and significantly degrade CDK9 with low cell toxicity. Therefore, we selected CD-5 as a chemical prober in the SILAC quantitative proteomic analysis, which disclosed that CD-5 could enormously lessen the lysine acetyltransferase KAT6A. Furthermore,KAT6A degradation induced by CD-5 repressed the levels of H3K14Ac and H3K23Ac. Lastly, the streptavidin immunoprecipitation(IP) assay confirmed a direct interaction between KAT6A and i CDK9. Collectively, our results uncover that KAT6A is a potential non-kinase target of i CDK9. Notably, this study also demonstrates that the PROTAC-SILAC strategy is an alternative approach for cellular target identification of bioactive molecules. | Mingtao Ao Jun Wu Yin Cao Yaohui He Yuxiang Zhang Xiang Gao Yuhua Xue Meijuan Fang Zhen Wu | 2023 | Chinese Chemical Letters2023，34，4： | 1 |

| 12 | Remnant fertilizer monitoring system for maize fertilizer applicators显示文摘A remnant fertilizer monitoring system utilizing three-dimensional(3D)reconstruction was proposed to detect the amount of remaining fertilizer in the applicator’s tank.Bench tests were carried out to compare the performance of four algorithms to estimate the remnant fertilizer amount:fertilizer remnant monitoring biharmonic spline algorithm(V4),natural nearest-neighbor algorithm(Natural),linear algorithm(Linear),cubic algorithm(Cubic).The average relative error for remnant fertilizer monitoring is 7.33%for the Linear algorithm,7.30%for the Natural algorithm,5.18%for the Cubic algorithm,and 4.30%for the V4 algorithm.Field tests are conducted at three fertilization rates to compare the performances of the V4 and Cubic algorithms.The average relative error for discharged fertilizer monitoring is 8.64%for the Cubic algorithm,which is 1.91%lower than that of the V4 algorithm.The results show that the Cubic algorithm has the best performance for remnant fertilizer monitoring.The average relative error of remnant fertilizer monitoring is 2.42%for the Cubic algorithm,which is 0.43%lower than that of the V4 algorithm.The response time of the remnant fertilizer monitoring system is 0.26 s.The results demonstrate that the proposed remnant fertilizer monitoring system is highly accurate and suitable for real-time applications. | Yaohui Zhang Kailiang Zhang Yang Yu Dongxing Zhang Li Yang Tao Cui Xiantao He | 2023 | International Journal of Agricultural and Biological Engineering2023，16，5： | 0 |
| 13 | Additive Manufacturing of Continuous Fiber-Reinforced Polymer Composite Sandwich Structures with Multiscale Cellular Cores显示文摘The use of composite sandwich structures with cellular cores is prevalent in lightweight designs owing to their superior energy-absorbing abilities.However,current manufacturing processes,such as hot-press molding and mold pressing,require multiple steps and complex tools,thus limiting the exploration of advanced sandwich structure designs.This study reports a novel multi-material additive manufacturing(AM)process that allows the single-step production of continuous fiber-reinforced polymer composite(CFRPC)sandwich structures with multiscale cellular cores.Specifically,the integration of CFRPC-AM and in situ foam AM processes provides effective and efficient fabrication of CFRPC panels and multiscale cellular cores with intricate designs.The cellular core design spans three levels:microcellular,unit-cell,and graded structures.Sandwich structures with a diverse set of unit-cell designs,that is,rhombus,square,honeycomb,and re-entrant honeycomb,were fabricated and their flexural behaviors were studied experimentally.The results showed that the sandwich structure with a rhombus core design possessed the highest flexural stiffness,strength,and specific energy absorption.In addition,the effect of the unit-cell assembly on the flexural performance of the CFRP composite sandwich structure was examined.The proposed design and fabrication methods open new avenues for constructing novel and high-performance CFRPC structures with multiscale cellular cores that cannot be obtained using existing approaches. | Zhenhu Wang Yaohui Wang Jian He Ke Dong Guoquan Zhang Wenhao Li Yi Xiong | 2023 | Chinese Journal of Mechanical Engineering(Additive Manufacturing Frontiers)2023，2，3： | 0 |
| 14 | Interdecadal variability in ecosystem health of Changjiang (Yangtze) River estuary using estuarine biotic integrity index显示文摘Ichthyoplankton samples were collected from Changjiang(Yangtze)River estuary in May 2016.Species composition was studied by DNA barcoding and morphological identification.To make better use of the estuarine biotic integrity index(EBI)to assess the ecosystem health of the Changjiang River estuary over the past 30 years,we collected the data of a spring ichthyoplankton survey in the estuary from 1986 to 2016.The EBI was calculated using 12 evaluation metrics,namely,the number of total ichthyoplankton species,estuarine spawning species,estuarine nursery species,estuarine resident species,benthic species,pelagic species,and intolerant species,and the percentages of tolerant species,omnivores,insectivores,carnivores,and natural hybrid species.EBI was calculated in spring in four periods(1986,1999,2007,and 2016)by assigning points of 1,3 or 5,giving values of 50,38,36,and 32,respectively,corresponding to“Good”,“Fair-Poor”,“Fair-Poor”,and“Poor”EBI levels,respectively.Changes in species composition were the primary reason for the significant decreases in EBI between 1986 and 1999,and for the large differences between 1986 and 2007 and between 2007 and 2016.The changes in species composition were influenced by declines in ichthyoplankton species,pollution sensitive species,estuarine nursery species and estuarine sedentary species,and an increase in pollution resistant species.An analysis of EBI interdecadal variability showed that the health status of the Changjiang River estuary ecosystem over the last 30 years first declined and then stabilized at a lower level.This result further settled the argument for urgent protection and restoration of the Changjiang River estuary. | Shouhai LIU Haijing ZHANG Yanlong HE Xiangsheng CHENG Haofei ZHANG Yutao QIN Xi JI Riguang HE Yaohui CHEN | 2021 | Journal of Oceanology and Limnology2021，39，4： | 0 |
| 15 | Halloysite‒gold core‒shell nanosystem synergistically enhances thermal conductivity and mechanical properties to optimize the wear-resistance of a pheonlic-PBO/PTFE textile composite liner显示文摘Polymer-textile liner composites have potential applications in aerospace applications for reducing the abrasion damage of moving parts during operation owing to their self-lubrication,light weight,and high loading capacity.Herein,Au nanoparticles(AuNPs)are successfully loaded into the lumen of halloysite nanotubes(HNTs)to construct an HNTs‒Au peasecod core‒shell nanosystem to optimize the wear resistance of phenolic resin-based poly(p-phenylene benzobisoxazole)(PBO)/polytetrafluoroethylene(PTFE)textile composites.Transmission electron microscope(TEM)characterization reveals that the AuNPs are well-dispersed inside the HNTs,with an average diameter of 6‒9 nm.The anti-wear performance of the HNTs and Au-reinforced PBO/PTFE composites is evaluated using a pin-on-disk friction tester at 100 MPa.Evidently,the addition of HNTs‒Au induces a 27.9%decrease in the wear rate of the composites.Possible anti-wear mechanisms are proposed based on the analyzed results of the worn surface morphology and the cross-section of the tribofilm obtained by focused ion beam transmission electron microscopy. | Yanling WANG Zhaozhu ZHANG Meng LIU Yaohui HE Peilong LI Junya YUAN Mingming YANG Weimin LIU | 2023 | Friction2023，11，12： | 0 |

| 18 | Spontaneous,scalable,and self-similar superhydrophobic coatings for all-weather deicing显示文摘Herein,we proposed and demonstrated a facile and scalable strategy to fabricate multifunctional self-similar superhydrophobic coatings.Firstly,a hydrophobic cationic cellulose derivative containing imidazolium cation was synthesized by a controllable derivatization.It could effectively disperse one-dimensional(1D)multi-walled carbon nanotubes(MWCNT),because the imidazolium cations formed cation–πinteractions with MWCNT.Further,the synergy effect of the cationic cellulose derivative and MWCNT dispersed two-dimensional(2D)reduced graphene oxide(rGO)to obtain a three-components nano-dispersion.Finally,via a simple spaying process,a superhydrophobic coating with self-similar micro-nano structures spontaneously formed from inside to outside,owing to the various nanostructures with different shapes and sizes in the dispersion and the adhesive effect of the cellulose derivative.This superhydrophobic coating was easy to scale,exhibited superior stability owing to the renewal micro-nano structures.It retained the superhydrophobicity even if it was treated by rubbing for 1500 times.Moreover,it had outstanding photo-thermal and Joule-heating performance,because of the strong solar absorption and high electrical conductivity of MWCNT and rGO.It provided both passive anti-icing and active deicing effects.Thus,it could achieve all-weather anti-icing for wind power generators under sunlight and low voltage conditions.Such facile preparation method and multifunctional renewable superhydrophobic coating hold great application prospects. | Yaohui Cheng Yirong Wang Xin Zhang Jinming Zhang Zhiyuan He Jianjun Wang Jun Zhang | 2023 | Nano Research2023，16，5： | 0 |
