| 1 | Comparison of microstructures and mechanical properties of composite extruded AZ31 sheets显示文摘The microstructures and mechanical properties of the composite extruded AZ31/AZ31 and AZ31/4047 Al sheets were investigated and made a comparison to the conventional extruded AZ31 sheet.Owing to the introduced intense shear deformation at the interface during the composite extrusion,grain refinement and tilted texture were detected in AZ31 layers of the AZ31/AZ31 and AZ31/4047 Al sheets,while the conventional extruded AZ31 sheet exhibited a relative coarse,inhomogeneous microstructure and strong basal texture.The compressiontension yield ratio was increased gradually from the AZ31 to the AZ31/AZ31 and AZ31/4047 Al sheets.Besides,the AZ31/4047 Al sheet could successfully accomplish the whole bending forming process at room temperature,while the AZ31 and AZ31/AZ31 sheets were both bend-formed to failure with significant cracks in the outer tensile region under the identical bending parameters.Moreover,under the same bending strain,both the outward offset degree of strain neutral layer and the sheet thickening were more serious in the AZ31/4047 Al composite sheet than those of the AZ31 and AZ31/AZ31 sheets.The foremost reason was the quite wide gap of material properties between Mg alloy AZ31 layer(tensile loading in the outer region)and Al 4047 layer(compressive loading in the inner region). | Yanfu Chai Yan Song Bin Jiang Jie Fu Zhongtao Jiang Qingshan Yang Haoran Sheng Guangsheng Huang Dingfei Zhang Fusheng Pan | 2019 | Journal of Magnesium and Alloys2019，7，4： | 11 |
| 2 | Emerging roles of transforming growth factor β signaling in wet age-related macular degeneration显示文摘Age-related macular degeneration (AMD) is one of the major causes of irreversible blindness among aging populations in developed countries and can be classified as dry or wet according to its progression.Wet AMD,which is characterized by angiogenesis on the choroidal membrane,is uncommonly seen but more severe.Controlling or completely inhibiting the factors that contribute to the progression of events that lead to angiogenesis may be an effective strategy for treating wet AMD.Emerging evidence has shown that transforming growth factor-β(TGF-β) signaling plays a significant role in the progression of wet AMD.In this review,we described the roles of and changes in TGF-β signaling in the development of AMD and discussed the mechanisms of the TGF-β superfamily in choroidal neovascularization (CNV) and wet AMD,including the modulation of angiogenesis-related factors,inflammation,vascular fibrosis,and immune responses,as well as cross-talk with other signaling pathways.These remarkable findings indicate that TGF-β signaling is a potential target for wet AMD treatment. | Kai Wang Haoran Li Ruipu Sun Chaxian Liu Yunfei Luo Shuhua Fu Ying Ying | 2019 | Acta Biochimica et Biophysica Sinica2019，51，1： | 5 |
| 3 | Unveiling annealing texture formation and static recrystallization kinetics of hot-rolled Mg-Al-Zn-Mn-Ca alloy显示文摘The development of Mg-Al-Zn-Mn-Ca series alloys provides a potential prospect to achieve high strength and formability at room temperature(RT).The formation of elliptical annular texture is treated as a crucial factor for the enhanced RT formability.However,the origin of such an elliptical annular texture formation has been rarely reported.Herein,we unveiled the formation and evolution of elliptical annular texture in the hot-rolled Mg-1.6 Al-0.8 Zn-0.4 Mn-0.5 Ca(AZMX1100,wt.%)alloy after annealing at different temperatures for 1 h,and its static recrystallization(SRX)kinetics in given annealing temperature for different time.The results revealed that the formation of elliptical annular texture in the hot-rolled AZMX1100 alloy after annealing was derived from nucleation-oriented SRX mechanism,which took place in 200-300°C,induced by cracked chain-shaped Al2 Ca phases,contraction twins,intersections of double twins,intersections of double twins and grain boundaries and non-basal slips.On further annealing from300-450°C,the grains with 45°–70°transverse direction(TD)preferentially grew,which made elliptical annular texture extended along the TD.Based on the Johnson-Mehl-Avrami-Kolmogorov(JMAK)model,Avrami exponent n value was estimated to be 0.68–1.02,attributed to non-random SRX nucleation,giving rise to the lower activation energy QRof nucleation of^74.24 k J/mol.Since the co-segregation of Al,Zn and Ca atoms in grain boundaries created a strong interaction of solutes and grain boundaries,the hot-rolled AZMX1100 alloy exhibited the higher activation energy Qg(~115.48 k J/mol)of grain growth. | Qinghang Wang Bin Jiang Aitao Tang Jie Fu Zhongtao Jiang Haoran Sheng Dingfei Zhang Guangsheng Huang Fusheng Pan | 2020 | Journal of Materials Science & Technology2020，36，8： | 3 |
| 4 | Recent progress of morphable 3D mesostructures in advanced materials显示文摘Soft robots complement the existing efforts of miniaturizing conventional,rigid robots,and have the potential to revolutionize areas such as military equipment and biomedical devices.This type of system can accomplish tasks in complex and time-varying environments through geometric reconfiguration induced by diverse external stimuli,such as heat,solvent,light,electric field,magnetic field,and mechanical field.Approaches to achieve reconfigurable mesostructures are essential to the design and fabrication of soft robots.Existing studies mainly focus on four key aspects:reconfiguration mechanisms,fabrication schemes,deformation control principles,and practical applications.This review presents a detailed survey of methodologies for morphable mesostructures triggered by a wide range of stimuli,with a number of impressive examples,demonstrating high degrees of deformation complexities and varied multi-functionalities.The latest progress based on the development of new materials and unique design concepts is highlighted.An outlook on the remaining challenges and open opportunities is provided. | Haoran Fu Ke Bai Yonggang Huang Yihui Zhang | 2020 | Journal of Semiconductors2020，41，4： | 2 |
| 5 | Rapid report of seismic damage to buildings in the 2022 M 6.8 Luding earthquake,China显示文摘The report summarizes the observed damage to a variety of buildings near the epicenter of the M6.8 Luding earthquake in Sichuan Province,China.They include base-isolated buildings,multi-story reinforced concrete(RC)frame buildings,and masonry buildings.The near-field region is known to be tectonically highly active,and the local intensity level is the highest,that is,0.4g peak ground acceleration(PGA)for the design basis earthquake,in the Chinese zonation of seismic ground motion parameters.The extent of damage ranged from the weak-story collapse that claimed lives to the extensive nonstructural damage that suspended occupancy.The report highlights the first observation of the destruction of rubber bearings and viscous dampers in the isolation layer of Chinese seismically isolated buildings.It also features the rare observation of the brittle shear failure of RC columns in moment-resisting frames in a region of such a high seismic design requirement.Possible reasons that may have attributed to the reported damage are suggested by providing facts observed in the field.However,careful forensic analyses are needed before any conclusive judgment can be made. | Zhe Qu Baijie Zhu Yuteng Cao Haoran Fu | 2023 | Earthquake Research Advances2023，3，1： | 2 |
| 6 | Role of surface roughness in the magnesite flotation and its mechanism显示文摘Surface roughness has a significant influence on mineral flotation.The assisting effect of surface roughness on minerals flotation is extensively investigated from its physical properties(e.g.,the existing form of asperity and its size),however,the associated effect on mineral flotation based on the differences in surface chemical property caused by surface roughness has been rarely touched.With such a question in mind,in this study,we investigated the flotation recoveries of two batches of magnesite particles with varying degree of surface roughness produced by two different mills,and associated the flotation performances to their surface chemical properties(amount of adsorption sites for the collector)via a series of detections,including Scanning Electron Microscope-Energy Dispersive Spectrometry(SEM-EDS)observations,X-ray photoelectron spectroscopy(XPS)analysis,adsorption capacity tests,and contact angle measurements.Finally,we concluded that rougher magnesite particles could provide more active sites(Mg^(2+))for a larger capacity of sodium oleate(NaOL),thereby improving the hydrophobicity and floatability. | Zhanglei Zhu Yafeng Fu Wanzhong Yin Haoran Sun Keqiang Chen Yuan Tang Bin Yang | 2022 | Particuology2022，20，3： | 2 |
| 7 | Wood plastic composites based wood wall’s structure and thermal insulation performance显示文摘In order to solve the problem of poor thermal insulation in the current wood-plastic building,two kinds of structural wood wall integrated with wood plastic composite(WPC)are designed,and the thermal insulation performances of the walls are studied.The results show that the WPC integrated wall with frame-shear structure has a good stability,and the excellent performance of the WPC can be fully realized.Wall studs and wall panels are important factors affecting the thermal performance of the walls.Wood plastic materials can meet the thermal performance requirements of the walls.The single-layer frame walls and double-layer frame walls integrated with the WPC both have a good thermal performance.According to‘Design Standard for Energy Efficiency of Public Buildings(GB 50189-2015)’,the heat transfer coefficient of the single-layer frame wall integrated with 20 mm thick WPC wall boards and WPC wall studs is 0.414 W/(m^(2)•K),which can meet the standard of wall thermal levelⅡt and is suitable for cold areas.The heat transfer coefficient of the double-layer frame wall integrated with 50 mm thick WPC wall panel and WPC wall studs is 0.207 W/(m^(2)•K),which can meet the standard of wall thermal levelⅠt and is suitable for severe cold areas. | Lu Zhang Zehua Chen Haoran Dong Shuai Fu Lan Ma Xiaojun Yang | 2021 | Journal of Bioresources and Bioproducts2021，6，1： | 1 |
| 8 | Efficient degradation of organic pollutants by S-NaTaO_(3)/biochar under visible light and the photocatalytic performance of a permonosulfate-based dual-effect catalytic system显示文摘Removing large concentrations of organic pollutants from water efficiently and quickly under visible light is essential to developing photocatalytic technology and improving solar energy efficiency.This study used a simple hydrothermal method to prepare a non-metallic,S-doped NaTaO_(3)(S-NTO) photocatalyst,which was then loaded onto biochar (BC) to form a S-NTO/BC composite photocatalyst.After uniform loading onto BC,the S-NTO particles transformed from cubic to spherical.The photogenerated electron-hole pair recombination probability of the composite photocatalyst was significantly lower than those of the NTO particles.The light absorption range of the catalyst was effectively widened from 310 nm UV region to visible region.In addition,a dual-effect catalytic system was constructed by introducing peroxymonosulfate (PMS) into the environment of the pollution to be degraded.The Rhodamine B,Methyl Orange,Acid Orange 7,tetracycline,and ciprofloxacin degradation efficiency at 40 mg/L reached 99.6%,99.2%,84.5%,67.1%,and 70.7%,respectively,after irradiation by a 40 W lamps for 90 min.The high-efficiency visible-light catalytic activity of the dual-effect catalytic system was attributed to doping with non-metallic sulfur and loading of catalysts onto BC.The development of this dual-effect catalytic system provides new ideas for quickly and efficiently solving the problem of high-concentration organic pollution in aqueous environments,rationally and fully utilizing solar energy,and expanding the application of photocatalytic technology to practice. | Yuehui Tai Jinlong Sun Haoran Tian Fuyue Liu Boyu Han Wei Fu Zhangpei Liu Xiuye Yang Qifeng Liu | 2023 | Journal of Environmental Sciences2023，，3： | 1 |

| 10 | Miniaturization of mechanical actuators in skin-integrated electronics for haptic interfaces显示文摘Skin-integrated electronics,also known as electronic skin(e-skin);are rapidly developing and are gradually being adopted in biomedical fields as well as in our daily lives.E-skin capable of providing sensitive and high-resolution tactile sensations and haptic feedback to the human body would open a new e-skin paradigm for closed-loop human-machine interfaces.Here,we report a class of materials and mechanical designs for the miniaturization of mechanical actuators and strategies for their integration into thin,soft e-skin for haptic interfaces.The mechanical actuators exhibit small dimensions of 5 mm diameter and 1.45 mm thickness and work in an electromagnetically driven vibrotactile mode with resonance frequency overlapping the most sensitive frequency of human skin.Nine mini actuators can be integrated simultaneously in a small area of 2 cm×2 cm to form a 3×3 haptic feedback array,which is small and compact enough to mount on a thumb tip.Furthermore,the thin,soft haptic interface exhibits good mechanical properties that work properly during stretching,bending,and twisting and therefore can conformally fit onto various parts of the human body to afford programmable tactile enhancement and Braille recognition with an accuracy rate over 85%. | Dengfeng Li Jiahui He Zhen Song Kuanming Yao Mengge Wu Haoran Fu Yiming Liu Zhan Gao Jingkun Zhou Lei Wei Zhengyou Zhang Yuan Dai Zhaoqian Xie Xinge Yu | 2021 | Microsystems & Nanoengineering2021，7，5： | 1 |

| 12 | Role of tannin pretreatment in flotation separation of magnesite and dolomite显示文摘Flotation separation of magnesite and its calcium-containing carbonate minerals is a difficult problem.Recently,new regulat-ors have been proposed for magnesite flotation decalcification,although traditional regulators such as tannin,water glass,sodium carbon-ate,and sodium hexametaphosphate are more widely used in industry.However,they are rarely used as the main regulators in research because they perform poorly in magnesite and dolomite single-mineral flotation tests.Inspired by the limonite presedimentation method and the addition of a regulator to magnesite slurry mixing,we used a tannin pretreatment method for separating magnesite and dolomite.Microflotation experiments confirmed that the tannin pretreatment method selectively and largely reduces the flotation recovery rate of dolomite without affecting the flotation recovery rate of magnesite.Moreover,the contact angles of the tannin-pretreated magnesite and dolomite increased and decreased,respectively,in the presence of NaOl.Zeta potential and Fourier transform infrared analyses showed that the tannin pretreatment method efficiently hinders NaOl adsorption on the dolomite surface but does not affect NaOl adsorption on the magnesite surface.X-ray photoelectron spectroscopy and density functional theory calculations confirmed that tannin interacts more strongly with dolomite than with magnesite. | Xiufeng Gong Jin Yao Jun Guo Bin Yang Haoran Sun Wanzhong Yin Yulian Wang Yafeng Fu | 2024 | International Journal of Minerals,Metallurgy and Materials2024，31，3： | 0 |
| 13 | Failure mechanisms in flexible electronics显示文摘The rapid evolution of flexible electronic devices promises to revolutionize numerous fields by expanding the applications of smart devices.Nevertheless,despite this vast potential,the reliability of these innovative devices currently falls short,especially in light of demanding operation environment and the intrinsic challenges associated with their fabrication techniques.The heterogeneity in these processes and environments gives rise to unique failure modes throughout the devices'lifespan.To significantly enhance the reliability of these devices and assure long-term performance,it is paramount to comprehend the underpinning failure mechanisms thoroughly,thereby,enabling,optimal design solutions.A myriad of investigative efforts have been dedicated to unravel these failure mechanisms,utilizing a spectrum of tools from analytical models,numerical methods,to advanced characterization methods.This review delves into the root causes of device failure,scrutinizing both the fabrication process and the operation environment.Next,We subsequently address the failure mechanisms across four commonly observed modes:strength failure,fatigue failure,interfacial failure,and electrical failure,followed by an overview of targeted characterization methods associated with each mechanism.Concluding with an outlook,we spotlight ongoing challenges and promising directions for future research in our pursuit of highly resilient flexible electronic devices. | Zhehui Zhao Haoran Fu Ruitao Tang Bocheng Zhang Yunmin Chen Jianqun Jiang | 2023 | International Journal of Smart and Nano Materials2023，14，4： | 0 |
| 14 | Leaky Gut Plays a Critical Role in the Pathophysiology of Autism in Mice by Activating the Lipopolysaccharide‑Mediated Toll‑Like Receptor 4-Myeloid Differentiation Factor 88-Nuclear Factor Kappa B Signaling Pathway显示文摘Increased intestinal barrier permeability,leaky gut,has been reported in patients with autism.However,its contribution to the development of autism has not been determined.We selected dextran sulfate sodium(DSS)to disrupt and metformin to repair the intestinal barrier in BTBR T+tf/J autistic mice to test this hypothesis.DSS treatment resulted in a decreased affinity for social proximity;however,autistic behaviors in mice were improved after the administration of metformin.We found an increased affinity for social proximity/social memory and decreased repetitive and anxiety-related behaviors.The concentration of lipopolysaccharides in blood decreased after the administration of metformin.The expression levels of the key molecules in the toll-like receptor 4(TLR4)–myeloid differentiation factor 88(MyD88)–nuclear factor kappa B(NF-κB)pathway and their downstream inflammatory cytokines in the cerebral cortex were both repressed.Thus,“leaky gut”could be a trigger for the development of autism via activation of the lipopolysaccharide-mediated TLR4–MyD88–NF-κB pathway. | Fang Li Haoran Ke Siqi Wang Wei Mao Cexiong Fu Xi Chen Qingqing Fu Xiaori Qin Yonghua Huang Bidan Li Shibing Li Jingying Xing Minhui Wang Wenlin Deng | 2023 | Neuroscience Bulletin2023，39，6： | 0 |
| 15 | Adversarial image detection based on the maximum channel of saliency maps显示文摘Studies have shown that deep neural networks(DNNs) are vulnerable to adversarial examples(AEs) that induce incorrect behaviors. To defend these AEs, various detection techniques have been developed. However, most of them only appear to be effective against specific AEs and cannot generalize well to different AEs. We propose a new detection method against AEs based on the maximum channel of saliency maps(MCSM). The proposed method can alter the structure of adversarial perturbations and preserve the statistical properties of images at the same time. We conduct a complete evaluation on AEs generated by 6 prominent adversarial attacks on the Image Net large scale visual recognition challenge(ILSVRC) 2012 validation sets. The experimental results show that our method performs well on detecting various AEs. | FU Haoran WANG Chundong LIN Hao HAO Qingbo | 2022 | Optoelectronics Letters2022，18，5： | 0 |
| 16 | Pore Formation Mechanism in W-C Hard Coatings Using Directed Energy Deposition on Tungsten Alloy显示文摘Porosity is a common phenomenon and can significantly hinder the quality of the coating.Here,the pore formation mechanism and the characteristics of the single tracks of the W-C coating using directed energy deposition(DED)are systematically investigated.The forming quality of the tracks,the distribution of the pores,and the elemental distribution near the pores are analyzed by the observations of the cross-sections of the tracks.The temperature field of the melt pool is discussed comprehensively to reveal the pore formation mechanism.The results confirm that Ni and Co evaporated during the DED process due to the high temperature of the melt pool.Pores were continuously produced adjacent to the fusion line when the melt pool was about to solidify since the temperature at the solidification front was higher than the boiling point of Ni.The vaporization area at the fusion line was proposed,where Ni could also evaporate at the time the melt pool started to solidify.The relationship between the solidification rate,the size of the vaporization area and the DED parameters(laser power and scanning speed)was established to discuss the causes of severe pores above the fusion line.This work contains a practical guide to reduce or eliminate the porosity in the coating preparation process on the surface of the tungsten alloy. | Xinrui Zhang Weijie Fu Chen Wang Zhenglong Lei Haoran Sun Xudong Li | 2024 | Acta Metallurgica Sinica(English Letters)2024，37，1： | 0 |
| 17 | Highly efficient synthesis of boron nitride nanotubes by catalytic chemical vapor deposition of boron/nickel containing precursors显示文摘High-purity and high-yield boron nitride nanotubes with large aspect ratio were prepared by a facile two-step process,including the synthesis of boron/nickel containing precursors by precipitation reactions and subsequent thermally catalytic chemical vapor deposition reactions.The influence of catalyst content and annealing temperature on the phase composition and microstructure of the products were investigated.The results show that it is difficult to exert the catalytic effect of nickel-based catalyst at low temperatures(<1400℃).At appropriate temperatures(1400-1500℃),highly crystalline boron nitride nanotubes with a length of more than 50 mm and a diameter of 50 nm are formed.The content of catalyst in the precursor mainly affects the morphology of the boron nitride product.If the content is too low,it is easy to form boron nitride particles;while high catalyst content can easily lead to catalyst aggregation and form a submicron one-dimensional boron nitride with unregular structure.Based on microstructural evolutions,phase changes,and thermodynamic analysis,the vapor-liquid-solid(V-L-S)growth mechanism of the tip growth mode dominates the formation of boron nitride nanotubes has also been verified. | Heng Wang Haoran Yang Yongzhi Peng Yulin Zheng Dongying Huang Pu Hu Yawei Li Zhengyi Fu | 2022 | Journal of Materiomics2022，8，6： | 0 |
| 18 | Effects of water adsorption on active site-dependent H_(2)activation over MgO nanoflakes显示文摘Understanding the effect of H_(2)O adsorption on reactant activation is of great importance in heterogeneous catalysis,which remains a grand challenge particularly in oxide catalyst systems with structural complexity.Herein,the effect of D_(2)O adsorption on D_(2)activation over MgO nanocatalysts at different temperatures has been investigated by transmission Fourier transform infrared(FT-IR)and temperature-programmed desorption(TPD).Two sets of hydride and hydroxyl species produced from D_(2)dissociation at more active and less active Mg-O pairs can be observed by FT-IR,which all desorb via the product of D_(2)as confirmed by TPD experiments.We find that the physically adsorbed D_(2)O overlayer does not affect the dissociation of D_(2)since D_(2)may pass through the molecular layer and access the surface-active sites.When D_(2)O is partially dissociated on the MgO surface,D_(2)can only dissociate at the remaining active sites until that dissociated-ODw groups from D_(2)O occupy all active sites.These findings provide a fundamental understanding of the effect of water adsorption on D_(2)activation on oxide catalysts. | Aiyi Dong Kun Li Rentao Mu Conghui Liu Rongtan Li Haoran Jia Le Lin Qiang Fu | 2023 | Nano Research2023，16，7： | 0 |
| 19 | Impact of extreme climate and train traffic loads on the performance of high-speed railway geotechnical infrastructures显示文摘High-speed railways are very important in global transportation.However,the railway subgrade is significantly affected by the environment due to its exposure to the atmosphere.At present,global warming is the primary trend in world climate change and seriously damages railway infrastructure.Owing to the coupling effect of extreme environmental and train loads,various subgrade problems tend to arise,such as settlement,ballast fouling,and mud pumping,thus inducing frequent railway accidents and reducing travel safety.Insights into the problems triggered by extreme climate and train loads are critical to the design and long-term operation of high-speed railway subgrades.This study therefore presents a detailed survey of recent advances in typical subgrade problems through analyzing the problem formation mechanisms and influences.Traditional and emerging detection/monitoring technologies in respect of subgrade problems are discussed in detail,as well as pre-accident and post-accident maintenance methods.Finally,according to the existing challenges in long-term subgrade shakedown assessment,an outlook on open opportunities is provided for future research. | Ying WU Haoran FU Xuecheng BIAN Yunmin CHEN | 2023 | Journal of Zhejiang University-Science A(Applied Physics & Engineering)2023，24，3： | 0 |
| 20 | Student Voice in Digital Classrooms:The Use of Digital Tools for Continuous Student Feedback Collection显示文摘For the proposed paper we report on the use of diverse digital tools for continuous student feedback collection and discuss students’ perceptions of and preferences for different approaches, with the aim of illustrating the influence of digital technologies on student voice. Five different digital tools have been investigated:TodaysMeet,Wiki,Padlet,Socrative, and WhatsApp. Eighty-eight non-English major freshmen from six randomly grouped classes at a Hong Kong university participated in the study. They were all enrolled in a credit-bearing course taught by one of the authors. After finishing all lectures of the course,we conducted a questionnaire survey among the participants,asking them what approach to feedback collection they felt most or least effective for communicating their feedback to teachers and classmates, which tool they felt most or least interesting, which tool they felt most or least convenient,and what advantages and disadvantages the five different digital tools have respectively. We also interviewed twenty participants to obtain further explanations of their answers to the questionnaires. The results showed that generally Padlet was regarded as the most liked and Wiki the least liked tool by the participants.Students highly valued features like effectiveness and interestingness, and considered convenience comparatively less important. | ZOU Di XIE Haoran Fu Lee WANG | 2016 | 外语教育2016，，1： | 0 |
