| 3 | Quantitative nanoscale mapping of three-phase thermal conductivities in filled skutterudites via scanning thermal microscopy显示文摘In the last two decades, a nano structuring paradigm has been successfully applied in a wide range of thermoelectric materials, resulting in significant reduction in thermal conductivity and superior thermoelectric performance. These advances, however, have been accomplished without directly investigating the local thermoelectric properties, even though local electric current can be mapped with high spatial resolution. In fact, there still lacks an effective method that links the macroscopic thermoelectric performance to the local micro structures and properties. Here, we show that local thermal conductivity can be mapped quantitatively with good accuracy, nanometer resolution and one-to-one correspondence to the micro structure using a three-phase skutterudite as a model system. Scanning thermal microscopy combined with finite element simulations demonstrate close correlation between sample conductivity and probe resistance,enabling us to distinguish thermal conductivities spanning orders of magnitude, yet resolving thermal variation across a phase interface with small contrast. The technique thus provides a powerful tool to correlate local thermal conductivities, micro structures and macroscopic properties for nano structured materials in general and nano structured thermo electrics in particular. | ehsan nasr esfahani feiyue ma shanyu wang yun ou jihui yang jiangyu li | 2018 | National Science Review2018，5，1： | 6 |

| 5 | Insight into vitronectin structural evolution on material surface chemistries: The mediation for cell adhesion显示文摘Biomaterial surface chemistry engenders profound consequences on cell adhesion and the ultimate tissue response by adsorbing proteins from extracellular matrix,where vitronectin(Vn)is involved as one of the crucial mediator proteins.Deciphering the adsorption behaviors of Vn in molecular scale provides a useful account of how to design biomaterial surfaces.But the details of structural dynamics and consequential biological effect remain elusive.Herein,both experimental and computational approaches were applied to delineate the conformational and orientational evolution of Vn during adsorption onto self-assembled monolayers(SAMs)terminating with-COOH,-NH2,-CH3 and-OH.To unravel the interplay between cell binding and the charge and wettability of material surface,somatomedin-B(SMB)domain of Vn holding the RGD cell-binding motif was employed in molecular dynamics(MD)simulations,with orientation initialized by Monte Carlo(MC)method.Experimental evidences including protein adsorption,cell adhesion and integrin gene expressions were thoroughly investigated.The adsorption of Vn on different surface chemistries showed very complex profiles.Cell adhesion was enabled on all Vn-adsorbed surfaces but with distinct mechanisms mostly determined by conformational change induced reorientation.Higher amount of Vn was observed on negatively charged surface(COOH)and hydrophobic surface(CH3).However,advantageous orientations defined by RGD loop conditions were only obtained on the charged surfaces(COOH and NH2).Specifically,COOH surface straightened up the Vn molecules and accumulated them into a higher density,whereas CH3 surface squashed Vn and stacked them into higher density multilayer by tracking adsorption but with the RGD loops restrained.These findings may have a broad implication on the understanding of Vn functionality and would help develop new strategies for designing advanced biomaterials. | Tianjie Li Lijing Hao Jiangyu Li Chang Du Yingjun Wang | 2020 | Bioactive Materials2020，5，4： | 4 |
| 6 | Effect of loading on the Ni_2P/Al_2O_3 catalysts for the hydrotreating reactions显示文摘The 80%Ni2P/Al2O3 catalysts were prepared by the phosphidation of corresponding 80%Ni/Al2O3 with triphenylphosphine in liquid phase and compared with the 60%Ni2P/Al2O3 for hydrotreating reactions. Both the60%Ni2P/Al2O3 and 80%Ni2P/Al2O3 in comparison exhibited the small and uniform Ni2 P particles(6.3 and8.4 nm,respectively),high CO uptakes(305 and 345 μmol/g,respectively) and thus high activities for the hydrotreating reactions. After the hydrotreating reactions,the small and uniform Ni2 P particles were remained,although the CO uptakes on the used 60%Ni2P/Al2O3 and 80%Ni2P/Al2O3 were greatly decreased(to 68 and95 μmol/g,respectively) due to the incorporation of S into the Ni2 P surfaces. The 80%Ni2P/Al2O3 was found to be significantly more active than the 60%Ni2P/Al2O3 due to that the 80%Ni2P/Al2O3 possessed more,and more active Ni2 P sites than the 60%Ni2P/Al2O3,probably due to the less S incorporated in the 80%Ni2P/Al2O3 than in the 60%Ni2P/Al2O3 during the hydrotreating reactions. | Junen Wang Shaozhong Li Jun Xu Hui Chen Jiangyu Yuan Jianyi Shen | 2015 | Journal of Energy Chemistry2015，24，4： | 4 |

| 8 | Tectono-Sedimentary History of Southeastern Coast Region,China:a Synthesis显示文摘According to the ideas and concepts of systems dynamic of continent structure, using previous information related to the study area, combining analyses on orogenic belt, basin and magmatic rock, the present paper synthesizes the tectono-sedimentary development of southeastern coast region, China, with special emphasis on the mountain making, basining and magmafc activity. The tectonic evolution after Late Caledonian orogeny was dominated by alternating rifting and converging, subsiding and uplifting, mountain making and basining in central and southern parts of southeastern China and the adjacent regions to the east and west. Seventeen geologic events, nine events of plate or terrain convergence , and continental crust accretion, as well as eight events of intracontinental rifting and basin faulting , are closely related to the tectonic and sedimentary evolution of the study area.

| 9 | A Comparative Study on the Dominant Factors Responsible for the Weaker-than-expected El Ni?o Event in 2014显示文摘Anomalous warming occurred in the equatorial central-eastern Pacific in early May 2014,attracting much attention to the possible occurrence of an extreme El Ni?o event that year because of its similarity to the situation in early 1997. However,the subsequent variation in sea surface temperature anomalies(SSTAs) during summer 2014 in the tropical Pacific was evidently different to that in 1997,but somewhat similar to the situation of the 1990 aborted El Ni?o event. Based on NCEP(National Centers for Environmental Prediction) oceanic and atmospheric reanalysis data,the physical processes responsible for the strength of El Ni?o events are examined by comparing the dominant factors in 2014 in terms of the preceding instability of the coupled ocean–atmosphere system and westerly wind bursts(WWBs) with those in 1997 and 1990,separately. Although the unstable ocean–atmosphere system formed over the tropical Pacific in the preceding winter of 2014,the strength of the preceding instability was relatively weak. Weak oceanic eastward-propagating downwelling Kelvin waves were forced by the weak WWBs over the equatorial western Pacific in March 2014,as in February 1990. The consequent positive upper-oceanic heat content anomalies in the spring of 2014 induced only weak positive SSTAs in the central-eastern Pacific–unfavorable for the subsequent generation of summertime WWB sequences. Moreover,the equatorial western Pacific was not cooled,indicating the absence of positive Bjerknes feedback in early summer 2014. Therefore,the development of El Ni?o was suspended in summer 2014. | LI Jianying LIU Boqi LI Jiandong MAO Jiangyu | 2015 | Advances in Atmospheric Sciences2015，32，10： | 3 |
| 10 | Mapping the elastic properties of two-dimensional MoS_(2) via bimodal atomic force microscopy and finite element simulation显示文摘Elasticity is a fundamental mechanical property of two-dimensional(2D)materials,and is critical for their application as well as for strain engineering.However,accurate measurement of the elastic modulus of 2D materials remains a challenge,and the conventional suspension method suffers from a number of drawbacks.In this work,we demonstrate a method to map the in-plane Young’s modulus of mono-and bi-layer MoS_(2) on a substrate with high spatial resolution.Bimodal atomic force microscopy is used to accurately map the effective spring constant between the microscope tip and sample,and a finite element method is developed to quantitatively account for the effect of substrate stiffness on deformation.Using these methods,the in-plane Young’s modulus of monolayer MoS_(2) can be decoupled from the substrate and determined as 265±13 GPa,broadly consistent with previous reports though with substantially smaller uncertainty.It is also found that the elasticity of mono-and bi-layer MoS_(2) cannot be differentiated,which is confirmed by the first principles calculations.This method provides a convenient,robust and accurate means to map the in-plane Young’s modulus of 2D materials on a substrate. | Yuhao Li Chuanbin Yu Yingye Gan Peng Jiang Junxi Yu Yun Ou Dai-Feng Zou Cheng Huang Jiahong Wang Tingting Jia Qian Luo Xue-Feng Yu Huijuan Zhao Cun-Fa Gao Jiangyu Li | 2018 | npj Computational Materials2018，，1： | 3 |
| 11 | Mapping intrinsic electromechanical responses at the nanoscale via sequential excitation scanning probe microscopy empowered by deep data显示文摘Ever-increasing hardware capabilities and computation powers have enabled acquisition and analysis of big scientific data at the nanoscale routine, though much of the data acquired often turn out to be redundant,noisy and/or irrelevant to the problems of interest, and it remains nontrivial to draw clear mechanistic insights from pure data analytics. In this work, we use scanning probe microscopy(SPM) as an example to demonstrate deep data methodology for nanosciences, transitioning from brute-force analytics such as data mining, correlation analysis and unsupervised classification to informed and/or targeted causative data analytics built on sound physical understanding. Three key ingredients of such deep data analytics are presented. A sequential excitation scanning probe microscopy(SE-SPM) technique is first developed to acquire high-quality, efficient and physically relevant data, which can be easily implemented on any standard atomic force microscope(AFM). Brute-force physical analysis is then carried out using a simple harmonic oscillator(SHO) model, enabling us to derive intrinsic electromechanical coupling of interest.Finally, principal component analysis(PCA) is carried out, which not only speeds up the analysis by four orders of magnitude, but also allows a clear physical interpretation of its modes in combination with SHO analysis. A rough piezoelectric material has been probed using such a strategy, enabling us to map its intrinsic electromechanical properties at the nanoscale with high fidelity, where conventional methods fail.The SE in combination with deep data methodology can be easily adapted for other SPM techniques to probe a wide range of functional phenomena at the nanoscale. | Boyuan Huang Ehsan Nasr Esfahani Jiangyu Li | 2019 | National Science Review2019，6，1： | 2 |
| 12 | Large-scale multiferroic complex oxide epitaxy with magnetically switched polarization enabled by solution processing显示文摘Complex oxides with tunable structures have many fascinating properties,though high-quality complex oxide epitaxy with precisely controlled composition is still out of reach.Here we have successfully developed solution-based single-crystalline epitaxy for multiferroic(1-x)BiTi(1-y)/2FeyMg(1-y)/2O3–(x)CaTiO3(BTFM–CTO)solid solution in large area,confirming its ferroelectricity at the atomic scale with strong spontaneous polarization.Careful compositional tuning leads to a bulk magnetization of 0.07±0.035μB/Fe at room temperature,enabling magnetically induced polarization switching exhibiting a large magnetoelectric coefficient of 2.7–3.0×10^-7 s/m.This work demonstrates the great potential of solution processing in large-scale complex oxide epitaxy and establishes novel room-temperature magnetoelectric coupling in epitaxial BTFM–CTO film,making it possible to explore a much wider space of composition,phase,and structure that can be easily scaled up for industrial applications. | Cong Liu Feng An Paria S.M.Gharavi Qinwen Lu Junkun Zha Chao Chen Liming Wang Xiaozhi Zhan Zedong Xu Yuan Zhang Ke Qu Junxiang Yao Yun Ou Zhiming Zhao Xiangli Zhong Dongwen Zhang Nagarajan Valanoor Lang Chen Tao Zhu Deyang Chen Xiaofang Zhai Peng Gao Tingting Jia Shuhong Xie Gaokuo Zhong Jiangyu Li | 2020 | National Science Review2020，7，1： | 2 |
| 13 | Unexpected boost of thermoelectric performance by magnetic nanoparticles显示文摘Thermoelectric materials are capable of converting heat into electricity and vice versa,and thus they are attractive in waste heat recovery and solid-state thermal management.Nevertheless,thermoelectric technologies are only limited to niche applications so far,for example in space exploration,since it is rather challenging to enhance their conversion efficiency. | Jiangyu Li | 2017 | Science China Materials2017，60，10： | 2 |
| 14 | Double Magnetic Separation-assisted Fluorescence Method for Sensitive Detection of Ochratoxin A显示文摘A double magnetic separation-assisted fluorescence method was developed to rapidly detect ochratoxin A(OTA). The OTA aptamer functionalized magnetic nanomaterial(Fe3O4-Aptanier) and complementary DNA conjugated nitrogen-doped graphene quantum dots(NGQDs-cDNA) were used in this assay. Aptamer could hybridize with cDNA, which induced tlie NGQDs-cDNA to bind onto Fe3O4-Aptamer, and resulted in the fluorescence quenching of NGQDs. After the addition of OTA, the NGQDs-cDNA could release into the solution, and resulted in the recovery of fluorescence signal of NGQDs consequently. By utilizing the magnetic separation, the unbonded NGQDs-cDNA and residual Fe3O4-Aptamer were removed, which significantly increased the fluorescence signal intensity. OTA could be detected in the linear range of 10 nmol/L to 2000 nmol/L, with a limit of detection as 0.66 mnol/L. The advantages of this method include simple operation, good selectivity and high sensitivity, and this method can be used for the rapid detection of ochratoxin A in wheat and com. | WANG Chengke TAN Rong LI Jiangyu ZHANG Zexiang | 2019 | Chemical Research in Chinese Universities2019，35，3： | 2 |
| 15 | Dynamics and manipulation of ferroelectric domain walls in bismuth ferrite thin films显示文摘Ferroelectric domain walls differ from domains not only in their crystalline and discrete symmetry,but also in their electronic,magnetic,and mechanical properties.Although domain walls provide a degree of freedom to regulate the physical properties at the nanoscale;the relatively lower controllability prevents their practical applications in nano-devices.In this work;with the advantages of 3D domain configuration detection based on piezoresponse force microscopy;we find that the mobility of three types of domain walls(tail-to-tail,head-to-tail,head-to-head)in(001)BiFeO3 films varies with the applied electrical field.Under low voltages;head-to-tail domain walls are more mobile than other domain walls;while,under high voltages,tail-to-tail domain walls become rather active and possess relatively long average lengths.This is due to the high nucleation energy and relatively low growth energy for charged domain walls.Finally;we demonstrate the manipulation of domain walls through successive electric writings,resulting in well-aligned conduction paths as designed;paving the way for their application in advanced spintronic;memory and communication nano-devices. | Shuyu Xiao Yaming Jin Xiaomei Lu Sang-Wook Cheong Jiangyu Li Yang Li Fengzhen Huang Jinsong Zhu | 2020 | National Science Review2020，7，2： | 2 |
| 16 | The digestible phosphorus requirement in practical diet for largemouth bass(Micropterus salmoides)based on growth and feed utilization显示文摘The present study was conducted to estimate the optimum requirement of phosphorus in practical diets for largemouth bass(Micropterus salmoides).Six iso-energetic and iso-nitrogenous diets were formulated with the supplementation of monocalcium phosphate(MCP)of 0,5,10,15,20 and 25 g/kg in basal diet containing 350 g/kg fish meal,respectively.The digestible phosphorus of the six diets was measured as 5.7,6.7,7.8,8.7,9.3 and 10.0 g/kg,respectively.Each diet was randomly fed to triplicate groups of 25 juvenile fish(initial body weight,16.0±0.2 g)for 60 days.The results showed that weight gain increased,and feed conversion ratio decreased with the increase of dietary phosphorus.When dietary MCP exceeded 15 g/kg(digestible phosphorus of 8.7 g/kg),the WG and FCR were maintained at the similar values.The crude ash,phosphorus and calcium contents in whole body,apparent digestibility of phosphorus and protein retention also increased with the increasing phosphorus level in diets.Vertebrae phosphorus and calcium levels and plasma phosphorus showed no further increase when dietary MCP reached 20,20 and 10 g/kg with digestible phosphorus of 9.3,9.3 and 7.8 g/kg,respectively.Broken-line analysis indicated that the digestible phosphorus requirement for largemouth bass were 8.9,8.7 and 9.6 g/kg based on weight gain,feed conversion ratio and vertebral phosphorus content.In conclusion,the supplementation of MCP in a diet containing 350 g/kg fish meal improved the growth and feed utilization of largemouth bass,and the digestible phosphorus requirement was suggested to be 8.7–8.9 g/kg with MCP supplementation of 15.0–15.8 g/kg. | Pu Wang Xiaoqin Li Zhen Xu Dong Ji Ming He JiangYu Dang Xiang-jun Leng | 2022 | Aquaculture and Fisheries2022，7，6： | 2 |
| 17 | A Timescale Decomposed Threshold Regression Downscaling Approach to Forecasting South China Early Summer Rainfall显示文摘A timescale decomposed threshold regression(TSDTR) downscaling approach to forecasting South China early summer rainfall(SCESR) is described by using long-term observed station rainfall data and NOAA ERSST data. It makes use of two distinct regression downscaling models corresponding to the interannual and interdecadal rainfall variability of SCESR.The two models are developed based on the partial least squares(PLS) regression technique, linking SCESR to SST modes in preceding months on both interannual and interdecadal timescales. Specifically, using the datasets in the calibration period 1915–84, the variability of SCESR and SST are decomposed into interannual and interdecadal components. On the interannual timescale, a threshold PLS regression model is fitted to interannual components of SCESR and March SST patterns by taking account of the modulation of negative and positive phases of the Pacific Decadal Oscillation(PDO). On the interdecadal timescale, a standard PLS regression model is fitted to the relationship between SCESR and preceding November SST patterns. The total rainfall prediction is obtained by the sum of the outputs from both the interannual and interdecadal models. Results show that the TSDTR downscaling approach achieves reasonable skill in predicting the observed rainfall in the validation period 1985–2006, compared to other simpler approaches. This study suggests that the TSDTR approach,considering different interannual SCESR-SST relationships under the modulation of PDO phases, as well as the interdecadal variability of SCESR associated with SST patterns, may provide a new perspective to improve climate predictions. | Linye SONG Wansuo DUAN Yun LI Jiangyu MAO | 2016 | Advances in Atmospheric Sciences2016，33，9： | 2 |

| 19 | Broadband high-efficiency polymerized liquid crystal metasurfaces with spin-multiplexed functionalities in the visible显示文摘Traditional optical components are usually designed for a single functionality and narrow operation band,leading to the limited practical applications.To date,it is still quite challenging to efficiently achieve multifunctional performances within broadband operating bandwidth via a single planar optical element.Here,a broadband high-efficiency polarization-multiplexing method based on a geometric phase polymerized liquid crystal metasurface is proposed to yield the polarization-switchable functionalities in the visible.As proofs of the concept,two broadband high-efficiency polymerized liquid crystal metalenses are designed to obtain the spin-controlled behavior from diffraction-limited focusing to sub-diffraction focusing or focusing vortex beams.The experimental results within a broadband range indicate the stable and excellent optical performance of the planar liquid crystal metalenses.In addition,low-cost polymerized liquid crystal metasurfaces possess unique superiority in large-scale patterning due to the straightforward processing technique rather than the point-by-point nanopatterning method with high cost and low throughput.The high-efficiency liquid crystal metasurfaces also have unrivalled advantages benefiting from the characteristic with low waveguide absorption.The proposed strategy paves the way toward multifunctional and high-integrity optical systems,showing great potential in mobile devices,optical imaging,robotics,chiral materials,and optical interconnections. | XINJIAN LU XIAOYIN LI YINGHUI GUO MINGBO PU JIANGYU WANG YAXIN ZHANG XIONG LI XIAOLIANG MA XIANGANG LUO | 2022 | Photonics Research2022，10，6： | 2 |
