| 2 | Damage evolution and dynamic response of cement asphalt mortar layer of slab track under vehicle dynamic load显示文摘The damage evolution and dynamic performance of a cement asphalt(CA)mortar layer of slab track subjected to vehicle dynamic load is investigated in this paper.Initially,a statistical damage constitutive model for the CA mortar layer is developed using continuous damage mechanics and probability theory.In this model,the strength of the CA mortar elements is treated as a random variable,which follows the Weibull distribution.The inclusion of strain rate dependence affords considering its influence on the damage development and the transition between viscosity and elasticity.Comparisons with experimental data support the reliability of the model.A three-dimensional finite element(FE)model of a slab track is then created with the commercial software ABAQUS,where the devised model for the CA mortar is implemented as a user-defined material subroutine.Finally,a vertical vehicle model is coupled with the FE model of the slab track,through the wheel-rail contact forces,based on the nonlinear Hertzian contact theory.The evolution of the damage and of the dynamic performance of the CA mortar layer with various initial damage is investigated under the train and track interaction.The analysis indicates that the proposed model is capable of predicting the damage evolution of the CA mortar layer exposed to vehicle dynamic load.The dynamic compressive strain,the strain rate,and the induced damage increase significantly with an increase in the initial damage,whereas the dynamic compressive stress exhibits a sharp decrease with the increasing initial damage.Also,it is found that the strain rate dependence significantly influences the damage evolution and the dynamic behavior of the CA mortar layer. | ZHU ShengYang FU Qiang CAI ChengBiao SPANOS Pol D | 2014 | Science China(Technological Sciences)2014，57，10： | 19 |
| 3 | Multipartite entanglement concentration for nitrogen-vacancy center and microtoroidal resonator system显示文摘We describe a high efcient entanglement concentration protocol(ECP)for multi-particle less-entangled nitrogen-vacancy(N-V)center and microtoroidal resonator system.In the ECP,we only require one pair of less-entangled state,two auxiliary N-V center in microcavities and some single photons.After the photon passing through the microcavity,by measuring the polarization of the photon,a maximally entangled W state can be obtained with some success probability.This ECP does not need to destroy the solid qubit,which makes it more feasible.Moreover,by resorting to more single photons,it can be repeated to reach a high success probability.These features make this ECP useful in current long-distance quantum communications. | SHENG YuBo LIU Jiong ZHAO ShengYang ZHOU Lan | 2013 | Chinese Science Bulletin2013，58，28： | 10 |
| 4 | Elastic Aerogels of Cellulose Nanofibers@Metal–Organic Frameworks for Thermal Insulation and Fire Retardancy显示文摘Metal–organic frameworks(MOFs)with high microporosity and relatively high thermal stability are potential thermal insulation and flame-retardant materials.However,the difficulties in processing and shaping MOFs have largely hampered their applications in these areas.This study outlines the fabrication of hybrid CNF@MOF aerogels by a stepwise assembly approach involving the coating and cross-linking of cellulose nanofibers(CNFs)with continuous nanolayers of MOFs.The cross-linking gives the aerogels high mechanical strength but superelasticity(80%maximum recoverable strain,high specific compression modulus of^200 MPa cm3 g−1,and specific stress of^100 MPa cm3 g−1).The resultant lightweight aerogels have a cellular network structure and hierarchical porosity,which render the aerogels with relatively low thermal conductivity of^40 mW m−1 K−1.The hydrophobic,thermally stable MOF nanolayers wrapped around the CNFs result in good moisture resistance and fire retardancy.This study demonstrates that MOFs can be used as efficient thermal insulation and flame-retardant materials.It presents a pathway for the design of thermally insulating,superelastic fire-retardant nanocomposites based on MOFs and nanocellulose. | Shengyang Zhou Varvara Apostolopoulou‑Kalkavoura Marcus Vinicius Tavares da Costa Lennart Bergstrom Maria Stromme Chao Xu | 2020 | Nano-Micro Letters2020，12，1： | 10 |
| 5 | Influence of valence electron structures of phase and biphase interfaces of sulfides on hot brittleness in steel显示文摘This paper calculates the electron structures of phase of FeS, MnS and their biphase interface electron structures with austenite in steel. The precipitation and the transformation of FeS and MnS are investigated through studying the valence electron pair numbers on the strongest bond nA with the structure formation factor S. The continuity of electron density and its relation with stress are explored in the biphase interfaces with the electron density difference D. Using nA, S, D? we explain the reason why FeS can bring about hot brittleness in steel and the physical mechanism why MnS may eliminate or inhibit hot brittleness, based on which satisfying results are obtained by calculating several rare-earth sulfides. | LIU Yan1,3, LIU Zhilin1, ZHANG Chengwei1,2 & ZHOU Yingchun1 1.

| 6 | Pseudocapacitive materials for electrochemical capacitors:from rational synthesis to capacitance optimization显示文摘Among various energy-storage devices,electrochemical capacitors(ECs) are prominent power provision but show relatively low energy density.One way to increase the energy density of ECs is to move from carbon-based electric double-layer capacitors to pseudocapacitors,which manifest much higher capacitance.However,compared with carbon materials,the pseudocapacitive electrodes sufer from high resistance for electron and/or ion transfer,signiicantly restricting their capacity,rate capability and cyclability.Rational design of electrode materials ofers opportunities to optimize their electrochemical performance,leading to devices with high energy density while maintaining high power density.his paper reviews the diferent approaches of electrodes striving to advance the energy and power density of ECs. | Jie Wang Shengyang Dong Bing Ding Ya Wang Xiaodong Hao Hui Dou Yongyao Xia Xiaogang Zhang | 2017 | National Science Review2017，4，1： | 7 |
| 7 | Humic acid and metal ions accelerating the dechlorination of 4-chlorobiphenyl by nanoscale zero-valent iron显示文摘Transformation of polychlorinated biphenyls (PCBs) by zero-valent iron represents one of the latest innovative technologies for environmental remediation. The dechlorination of 4-chlorobiphenyl (4-ClBP) by nanoscale zero-valent iron (NZVI) in the presence of humic acid or metal ions was investigated. The results showed that the dechlorination of 4-ClBP by NZVI increased with decreased solution pH. When the initial pH value was 4.0, 5.5, 6.8, and 9.0, the dechlorination efficiencies of 4-ClBP after 48 hr were 53.8%, 47.8%, 35.7%, and 35.6%, respectively. The presence of humic acid inhibited the reduction of 4-ClBP in the first 4 hr, and then significantly accelerated the dechlorination by reaching 86.3% in 48 hr. Divalent metal ions, Co 2+ , Cu 2+ , and Ni 2+ , were reduced and formed bimetals with NZVI, thereby enhanced the dechlorination of 4-ClBP. The dechlorination percentages of 4-ClBP in the presence of 0.1 mmol/L Co 2+ , Cu 2+ and Ni 2+ were 66.1%, 66.0% and 64.6% in 48 hr, and then increased to 67.9%, 71.3% and 73.5%, after 96 hr respectively. The dechlorination kinetics of 4-ClBP by the NZVI in all cases followed pseudo-first order model. The results provide a basis for better understanding of the dechlorination mechanisms of PCBs in real environment. | Yu Wang Dongmei Zhou Yujun Wang Xiangdong Zhu Shengyang Jin | 2011 | Journal of Environmental Sciences2011，23，8： | 5 |
| 8 | Niobium Tungsten Oxide in a Green Water‑in‑Salt Electrolyte Enables Ultra‑Stable Aqueous Lithium‑Ion Capacitors显示文摘Aqueous hybrid supercapacitors are attracting increasing attention due to their potential low cost,high safety and eco-friendliness.However,the narrow operating potential window of aqueous electrolyte and the lack of suitable negative electrode materials seriously hinder its future applications.Here,we explore high concentrated lithium acetate with high ionic conductivity of 65.5 mS cm−1 as a green“water-in-salt”electrolyte,providing wide voltage window up to 2.8 V.It facilitates the reversible function of niobium tungsten oxide,Nb18W16O93,that otherwise only operations in organic electrolytes previously.The Nb18W16O93 with lithium-ion intercalation pseudocapacitive behavior exhibits excellent rate performance,high areal capacity,and ultra-long cycling stability.An aqueous lithium-ion hybrid capacitor is developed by using Nb18W16O93 as negative electrode combined with graphene as positive electrode in lithium acetate-based“water-in-salt”electrolyte,delivering a high energy density of 41.9 W kg−1,high power density of 20,000 W kg−1 and unexceptionable stability of 50,000 cycles. | Shengyang Dong Yi Wang Chenglong Chen Laifa Shen Xiaogang Zhang | 2020 | Nano-Micro Letters2020，12，12： | 4 |
| 9 | Synthesis of monolithic carbon aerogels with high mechanical strength via ambient pressure drying without solvent exchange显示文摘A simple,fast and cost-effective method for monolithic carbon aerogels(CAs) preparation was proposed through sol-gel polycondensation of resorcinol with fo rmaldehyde in a basic aqueous solution followed by ambient pressure drying without solvent exchange,and carbonization.The microstructure and network strength of CAs were tailored by adju sting the catalyst concentration([resorcinol]/[sodium carbonate] in the range of 300-2000),water content([deionized water]/[resorcinol] equals to 17 and 24,respectively),and gelation temperature(Tgel in the range of 30-90℃).Resultantly,the CAs with a wide range of density(0.30-1.13 g/cm3),high specific surface area(465-616 m2/g),high compressive strength(6.5-147.4 MPa)and low thermal conductivity(0.065-0.120 W·m-1 K-1) were obtained in this work.Moreover,the largesized CAs(100×100×20 mm3) can also be prepared by this method since the formed robust skeleton network can resist shrinkage/collapse of pore structure and prevent cracking during drying.The improved mechanical strength and monolithic forming abilities could be mainly attributed to the uniform arrangement of carbon particles and pores,fine particle size,abundant network structure and enhanced particle neck. | Zhi Yang Jian Li Xiaojing Xu Shengyang Pang Chenglong Hu Penglei Guo Sufang Tang Hui-Ming Cheng | 2020 | Journal of Materials Science & Technology2020，47，15： | 4 |
| 10 | Deep feature extraction and motion representation for satellite video scene classification显示文摘Satellite video scene classification(SVSC)is an advanced topic in the remote sensing field,which refers to determine the video scene categories from satellite videos.SVSC is an important and fundamental step for satellite video analysis and understanding,which provides priors for the presence of objects and dynamic events.In this paper,a two-stage framework is proposed to extract spatial features and motion features for SVSC.More specifically,the first stage is designed to extract spatial features for satellite videos.Representative frames are firstly selected based on the blur detection and spatial activity of satellite videos.Then the fine-tuned visual geometry group network(VGG-Net)is transferred to extract spatial features based on spatial content.The second stage is designed to build motion representation for satellite videos.The motion representation of moving targets in satellite videos is first built by the second temporal principal component of principal component analysis(PCA).Second,features from the first fully connected layer of VGG-Net are used as high-level spatial representation for moving targets.Third,a small network of long and short term memory(LSTM)is further designed for encoding temporal information.Two-stage features respectively characterize spatial and temporal patterns of satellite scenes,which are finally fused for SVSC.A satellite video dataset is built for video scene classification,including 7209 video segments and covering 8 scene categories.These satellite videos are from Jilin-1 satellites and Urthecast.The experimental results show the efficiency of our proposed framework for SVSC. | Yanfeng GU Huan LIU Tengfei WANG Shengyang LI Guoming GAO | 2020 | Science China(Information Sciences)2020，63，4： | 4 |

| 13 | Plasmonic silver/silver oxide nanoparticles anchored bismuth vanadate as a novel visible-light ternary photocatalyst for degrading pharmaceutical micropollutants显示文摘The degradation of pharmaceutical micropollutants is an intensifying environmental problem and synthesis of efficient photocatalysts for this purpose is one of the foremost challenges worldwide.Therefore,this study was conducted to develop novel plasmonic Ag/Ag2O/BiVO4 nanocomposite photocatalysts by simple precipitation and thermal decomposition methods,which could exhibit higher photocatalytic activity for mineralized pharmaceutical micropollutants.Among the different treatments,the best performance was observed for the Ag/Ag2O/BiVO4 nanocomposites (5 wt.%;10 min’s visible light irradiation)which exhibited 6.57 times higher photodegradation rate than the pure BiVO4.Further,the effects of different influencing factors on the photodegradation system of tetracycline hydrochloride (TC-HCl) were investigated and the feasibility for its practical application was explored through the specific light sources,water source and cycle experiments.The mechanistic study demonstrated that the photogenerated holes (h^+),superoxide radicals (·O2^-)and hydroxyl radicals (·OH) participated in TC-HCl removal process,which is different from the pure BiVO4 reaction system.Hence,the present work can provide a new approach for the formation of novel plasmonic photocatalysts with high photoactivity and can act as effective practical application for environmental remediation. | Shengyan Pu Zeng Yang Jing Tang Hui Ma Shengyang Xue Yingchen Bai | 2020 | Journal of Environmental Sciences2020，32，10： | 3 |
| 14 | Mechanical characteristic variation of ballastless track in highspeed railway:effect of train–track interaction and environment loads显示文摘Due to the fact that ballastless tracks in highspeed railways are not only subjected to repeated train–track dynamic interaction loads,but also suffer from complex environmental loads,the fundamental understanding of mechanical performance of ballastless tracks under sophisticated service conditions is an increasingly demanding and challenging issue in high-speed railway networks.This work aims to reveal the effect of train–track interaction and environment loads on the mechanical characteristic variation of ballastless tracks in high-speed railways,particularly focusing on the typical interface damage evolution between track layers.To this end,a finite element model of a double-block ballastless track involving the cohesive zone model for the track interface is first established to analyze the mechanical properties of the track interface under the loading–unloading processes of the negative temperature gradient load(TGL)followed by the same cycle of the positive TGL.Subsequently,the effect of wheel–rail longitudinal interactions on the nonlinear dynamic characteristics of the track interface is investigated by using a vehicle-slab track vertical-longitudinal coupled dynamics model.Finally,the influence of dynamic water pressure induced by vehicle dynamic load on the mechanical characteristics and damage evolution of the track interface is elucidated using a fluid–solid coupling method.Results show that the loading history of the positive and negative TGLs has a great impact on the nonlinear development and distribution of the track interface stress and damage;the interface damage could be induced by the wheel–rail longitudinal vibrations at a high vehicle running speed owing to the dynamic amplification effect caused by short wave irregularities;the vehicle dynamic load could produce considerable water pressure that presents nonlinear spatial–temporal characteristics at the track interface,which would lead to the interface failure under a certain condition due to the coupled dynamic effect of vehicle load and water pressure. | Shengyang Zhu Jun Luo Mingze Wang Chengbiao Cai | 2020 | Railway Engineering Science2020，28，4： | 3 |
| 15 | Quantifying the adsorption and uptake of CuO nanoparticles by wheat root based on chemical extractions显示文摘Extensive application of metal nanoparticles is attracting more attention because of their potential environmental risks.Many studies have focused on the uptake of metal nanoparticles (NPs) by plant,but the adsorption of nanoparticles on root surface is often mistakenly regarded as their uptake.This study optimized the methods to distinguish the adsorption and uptake of CuO-NPs on the wheat root by applying different metal competing ions (Na +,Mg 2+,and La 3+ ),surfactant (i.e.,sodium dodecyl benzene sulfonate,SDBS),or complexing agents like NaOAc and Na 4 EDTA,as well as ultrasonic technique.The results indicated that some CuO-NPs is strongly adsorbed on the plant root surface,and part of them by mechanical adhesion.Competing ions could not desorb the CuO-NPs from the root surface,while NaOAc and Na 4 EDTA well dissolved the adsorbed CuO-NPs.In addition,the uptake and adsorption of CuO-NPs increased with increasing exposure concentrations of CuO-NPs in the range of 5-200 mg/L.The amount of CuO-NPs adsorption is always lower than that of their uptake. | Dongmei Zhou Shengyang Jin Lianzhen Li Yu Wang Nanyan Weng | 2011 | Journal of Environmental Sciences2011，23，11： | 3 |
| 16 | Morphological differences in skeletal muscle atrophy of rats with motor nerve and/or sensory nerve injury显示文摘Skeletal muscle atrophy occurs after denervation. The present study dissected the rat left ventral root and dorsal root at L4-6 or the sciatic nerve to establish a model of simple motor nerve injury, sensory nerve injury or mixed nerve injury. Results showed that with prolonged denervation time, rats with simple motor nerve injury, sensory nerve injury or mixed nerve injury exhibited abnormal behavior, reduced wet weight of the left gastrocnemius muscle, decreased diameter and cross-sectional area and altered ultrastructure of muscle cells, as well as decreased cross-sectional area and increased gray scale of the gastrocnemius muscle motor end plate. Moreover, at the same time point, the pathological changes were most severe in mixed nerve injury, followed by simple motor nerve injury, and the changes in simple sensory nerve injury were the mildest. These findings indicate that normal skeletal muscle morphology is maintained by intact innervation. Motor nerve injury resulted in larger damage to skeletal muscle and more severe atrophy than sensory nerve injury. Thus, reconstruction of motor nerves should be considered first in the clinical treatment of skeletal muscle atrophy caused by denervation. | Lei Zhao Guangming Lv Shengyang Jiang Zhiqiang Yan Junming Sun Ling Wang Donglin Jiang | 2012 | Neural Regeneration Research2012，7，32： | 3 |
| 17 | DYNAMIC RECRYSTALLIZATION AND SUPERPLASTICITY IN Al-Li ALLOY显示文摘The behavior of dynamic recrystallization in the superplastic deformation of 8090 and 2091 aluminum-lithium alloys have been investigated.TEM observations indicated that dynamic recrystallization occurs at thetriple junction of grain boundaries.The measurement of grain boundary angle showed that recrystallization indynamic equilibrium exists in the process of superplastic deformation of 8090 Al-Li alloy.It is also indicatedthat,besides the role of refining grains and the grain boundary sliding,dynamic recrystallization playsconcurrently a role of stablizing microstructure.Thus dynamic rccrystallization can be used to induce metalssuperplasticity,which leads to a simplification of pretreatment for superplastic deformation. | Liu,Ziyi Cui,Jianzhong Bai,Guangrun Northeast University of Technology,Shengyang 110006,China | 1993 | 中国有色金属学会会刊:英文版1993，3，2： | 2 |
| 18 | High Initial Reversible Capacity and Long Life of Ternary SnO_(2)-Co-carbon Nanocomposite Anodes for Lithium-Ion Batteries显示文摘The two major limitations in the application of SnO_2 for lithium?ion battery(LIB) anodes are the large volume variations of SnO_2 during repeated lithiation/delithiation processes and a large irreversible capacity loss during the first cycle, which can lead to a rapid capacity fade and unsatisfactory initial Coulombic e ciency(ICE). To overcome these limitations, we developed composites of ultrafine SnO_2 nanoparticles and in situ formed Co(CoSn) nanocrystals embedded in an N?doped carbon matrix using a Co?based metal–organic framework(ZIF?67). The formed Co additives and structural advantages of the carbon?confined SnO_2/Co nanocomposite e ectively inhibited Sn coarsening in the lithiated SnO_2 and mitigated its structural degradation while facilitating fast electronic transport and facile ionic di usion. As a result, the electrodes demonstrated high ICE (82.2%), outstanding rate capability(~ 800 mAh g^(-1) at a high current density of 5 A g^(-1)), and long?term cycling stability(~ 760 mAh g^(-1) after 400 cycles at a current density of 0.5 A g^(-1)). This study will be helpful in developing high?performance Si(Sn)?based oxide, Sn/Sb?based sulfide, or selenide electrodes for LIBs. In addition, some metal organic frameworks similar to ZIF?67 can also be used as composite templates. | Pan Deng Jing Yang Shengyang Li Tian-E Fan Hong-Hui Wu Yun Mou Hui Huang Qiaobao Zhang Dong-Liang Peng Baihua Qu | 2019 | Nano-Micro Letters2019，11，1： | 2 |
| 19 | Yizhi Xingnao prescription improves the cognitive function of patients after a transient ischemic attack显示文摘Patients with mild cognitive impairment after a transient ischemic attack were included in this study. They were treated with Yizhi Xingnao prescription, ergoloid mesylates or aspirin for 60 days. Evaluation using the Montreal Cognitive Assessment Scale showed that cognitive function was significantly improved in all patients, especially after the combined treatment of Yizhi Xingnao and aspirin. The scores from the Montreal Cognitive Assessment Scale were improved overall and the effective treatment rate was as high as 79%, which was higher than patients treated with a combination of ergoloid mesylates and aspirin, or aspirin alone. Our experimental findings indicate that Yizhi Xingnao prescription can improve mild cognitive impairment after a transient ischemic attack, and that it is more effective than ergoloid mesylates. | Donglin Jiang Xing Chu Lingling Hu Shengyang Jiang Feng Hu Junming Sun Chengwan Li | 2012 | Neural Regeneration Research2012，7，6： | 2 |
