| 1 | Broadband achromatic metalens in terahertz regime显示文摘Achromatic focusing is essential for broadband operation, which has recently been realised from visible to infrared wavelengths using a metasurface. Similarly, multi-terahertz functional devices can be encoded in a desired metasurface phase profile. However, metalenses suffer from larger chromatic aberrations because of the intrinsic dispersion of each unit element. Here, we propose an achromatic metalens with C-shaped unit elements working from 0.3 to 0.8 THz with a bandwidth of approximately 91% over the centre frequency. The designed metalens possesses a high working efficiency of more than 68% at the peak and a relatively high numerical aperture of 0.385. We further demonstrate the robustness of our Cshaped metalens, considering lateral shape deformations and deviations in the etching depth. Our metalens design opens an avenue for future applications of terahertz meta-devices in spectroscopy, time-offlight tomography and hyperspectral imaging systems. | Qingqing Cheng Meilin Ma Dong Yu Zhixiong Shen Jingya Xie Juncheng Wang Nianxi Xu Hanming Guo Wei Hu Shuming Wang Tao Li Songlin Zhuang | 2019 | Science Bulletin2019，64，20： | 16 |
| 2 | Reactivation of γ-globin expression through Cas9 or base editor to treat β-hemoglobinopathies显示文摘Dear Editor,Mutations in the β-globin gene,the essential component of adult hemoglobin(HbA;a2p2),results in either a production of aberrant sickle hemoglobin(HbS)leading to sickle cell disease(SCD)or an insufficient β-globin synthesis leading to β-thalassemia.These two major forms of β-hemoglobinopathies cause impaired erythropoiesis and life-threatening anemia.Clinical evidence has suggested that reaaivation of fetal γ-globin(HBG)gene expression which is normally silenced after birth by certain genetic mutations can ameliorate the clinical course of β-hemoglobinopathies. | Liren Wang Linxi Li Yanlin Ma Handan Hu Qi Li Yang Yang Wenbang Liu Shuming Yin Wei Li Bin Fu Ryo Kurita Yukio Nakamura Mingyao Liu Yongrong Lai Dali Li | 2020 | Cell Research2020，30，3： | 14 |

| 4 | Spectral tomographic imaging with aplanatic metalens显示文摘Tomography is an informative imaging modality that is usually implemented by mechanical scanning,owing to the limited depth-of-field(DOF)in conventional systems.However,recent imaging systems are working towards more compact and stable architectures;therefore,developing nonmotion tomography is highly desirable.Here,we propose a metalens-based spectral imaging system with an aplanatic GaN metalens(NA=0.78),in which large chromatic dispersion is used to access spectral focus tuning and optical zooming in the visible spectrum.After the function of wavelength-switched tomography was confirmed on cascaded samples,this aplanatic metalens is utilized to image microscopic frog egg cells and shows excellent tomographic images with distinct DOF features of the cell membrane and nucleus.Our approach makes good use of the large diffractive dispersion of the metalens and develops a new imaging technique that advances recent informative optical devices. | Chen Chen Wange Song Jia-Wern Chen Jung-Hsi Wang Yu Han Chen Beibei Xu Mu-Ku Chen Hanmeng Li Bin Fang Ji Chen Hsin Yu Kuo Shuming Wang Din Ping Tsai Shining Zhu Tao Li | 2019 | Light(Science & Applications)2019，8，1： | 12 |
| 5 | Assessing the numbers of SNPs needed to establish molecular IDs and characterize the genetic diversityof soybean cultivars derived from Tokachi nagaha显示文摘The development of a core set of SNP molecular markers that could be widely used in soybean genetic research would greatly facilitate research into the genetic diversity of soybean.We conducted an analysis of Tokachi nagaha and 137 of its descendant soybean cultivars using 4044 SNP markers with the goal of determining the appropriate number of single-nucleotide polymorphisms(SNPs)needed to construct unambiguous molecular IDs and characterize genetic diversity based on a genetic distance matrix correlation method.When the number of SNPs was held constant,the number of accession pairs that could be distinguished increased as the polymorphism informative content(PIC)value of the SNPs increased.A core panel of 20 selected SNPs from 11 linkage groups with a mean PIC value of 0.3703 and a range of 0.3640–0.3749 was able to identify almost all of the accession pairs in our study[9445 pairs(99.92%)].The eight accession pairs that could not be identified with this core SNP set all originated from the same province and some of them had the same parental cultivars.The molecular IDs of the 138 accessions were constructed using the core 20 SNPs.It is known that both the number of SNPs and PIC values should be considered when SNPs are selected for use in the analysis of genetic diversity.In this study,when the PIC value was 0.3460,the correlation coefficient between the genetic distance matrices associated with a panel of 200 SNPs and the total population was>0.800,indicating satisfactory correlation.Our high-accuracy,high-resolution core SNP panel for germplasm fingerprinting and our findings about assessing genetic diversity will likely markedly improve the management and utilization efficiency of soybean germplasm resources. | Zhangxiong Liu Jun Li Xuhong Fan Nang Myint Phyu Sin Htwe Shuming Wang Wen Huang Jiyu Yang Lili Xing Lijun Chen Yinghui Li Rongxia Guan Ruzhen Chang Dechun Wang Lijuan Qiu | 2017 | The Crop Journal2017，5，4： | 10 |
| 6 | KD-S SiC_f/SiC composites with BN interface fabricated by polymer infiltration and pyrolysis process显示文摘Continuous silicon carbide fiber reinforced silicon carbide matrix(SiC_f/SiC) composites are attractive candidate materials for aerospace engine system and nuclear reactor system. In this paper, SiC_f/SiC composites were fabricated by polymer infiltration and pyrolysis(PIP) process using KD-S fiber as the reinforcement and the LPVCS as the precursor, while the BN interface layer was introduced by chemical vapor deposition(CVD) process using borazine as the single precursor. The effect of the BN interface layer on the structure and properties of the SiC_f/SiC composites was comprehensively investigated. The results showed that the BN interface layer significantly improved the mechanical properties of the KD-S SiC_f/SiC composites. The flexure strength and fracture toughness of the KD-S SiC_f/SiC composites were evidently improved from 314±44.8 to 818±39.6 MPa and 8.6± 0.5 to 23.0±2.2 MPa·m^(1/2), respectively. The observation of TEM analysis displayed a turbostratic structure of the CVD-BN interface layer that facilitated the improvement of the fracture toughness of the SiC_f/SiC composites. The thermal conductivity of KD-S SiC_f/SiC composites with BN interface layer was lower than that of KD-S SiC_f/SiC composites without BN interface layer, which could be attributed to the relative low thermal conductivity of BN interface layer with low crystallinity. | Honglei WANG Shitao GAO Shuming PENG Xingui ZHOU Haibin ZHANG Xiaosong ZHOU Bin Li | 2018 | Journal of Advanced Ceramics2018，7，2： | 10 |
| 7 | Vehicle Planar Motion Stability Study for Tyres Working in Extremely Nonlinear Region显示文摘Many researches on vehicle planar motion stability focus on two degrees of freedom(2DOF) vehicle model,and only the lateral velocity (or side slip angle) and yaw rate are considered as the state variables.The stability analysis methods,such as phase plane analysis,equilibriums analysis and bifurcation analysis,are all used to draw many classical conclusions.It is concluded from these researches that unbounded growth of the vehicle motion during unstable operation is untrue in reality thus one limitation of the 2DOF model.The fundamental assumption of the 2DOF model is that the longitudinal velocity is treated as a constant,but this is intrinsically incorrect.When tyres work in extremely nonlinear region,the coupling between the vehicle longitudinal and lateral motion becomes significant.For the purpose of solving the above problem,the effect of vehicle longitudinal velocity on the stability of the vehicle planar motion when tyres work in extremely nonlinear region is investigated.To this end,a 3DOF model which introducing the vehicular longitudinal dynamics is proposed and the 3D phase space portrait method is employed for visualization of vehicle dynamics.Through the comparisons of the 2DOF and 3DOF models,it is discovered that the vehicle longitudinal velocity greatly affects the vehicle planar motion,and the vehicle dynamics represented in phase space portrait are fundamentally different from that of the 2DOF model.The vehicle planar motion with different front wheel steering angles is further represented by the corresponding vehicle route,yaw rate and yaw angle.These research results enhance the understanding of the stability of the vehicle system particularly during nonlinear region,and provide the insight into analyzing the attractive region and designing the vehicle stability controller,which will be the topics of future works. | LIU Li SHI Shuming SHEN Shuiwen CHU Jiangwei | 2010 | Chinese Journal of Mechanical Engineering2010，23，2： | 8 |
| 8 | Characterization of Hemicelluloses Extracted from Populus tomentosa Carr. by the Hydrothermal Method with Ethanol显示文摘The aim of this study was to investigate the hemicelluloses extracted from Populus tomentosa Carr.by the hydrothermal method with ethanol.The influence of ethanol concentration on the hemicellulosic fractions was systematically studied.The chemical compositions and structural features of the hemicellulosic fractions were investigated by a combination of sugar analysis,gel-permeation chromatography,Fourier transform infrared spectroscopy,and one-dimensional proton and carbon-13 nuclear magnetic resonance,and two-dimensional heteronuclear single quantum coherence spectroscopy.Neutral sugar analysis of the hemicellulosic fractions revealed that a higher ethanol concentration(45%~80%) favored the isolation of hemicelluloses with more side chains and lower glucose contents.The molecular weights of these polysaccharides ranged between 2842 g/mol and 5101 g/mol.The results of this study indicate that the hydrothermal ethanol process provides a new pretreatment strategy for the isolation and extraction of biomass. | LianHua Fu Shan Liu ShuMing Li YaYu Li MingGuo Ma | 2017 | Paper And Biomaterials2017，2，3： | 7 |
| 9 | The temporal-spatial distribution and changes of dissolved oxygen in the Changjiang Estuary and its adjacent waters for the last 50 a显示文摘The Changjiang Estuary and its adjacent waters form one of the most important estuarine and coastal areas in China. Multi source and long-term data are assembled to examine the temporal-spatial distribution features of dissolved oxygen(DO) in the Changjiang Estuary and its adjacent waters for the past 50 a. The results show that the DO concentration in the surface of different seasons generally stays stable, while the DO concentration in winter displays a slight increase for the last 50 a. The DO average concentration in winter and spring varies from 7to 11 mg/L, and in summer and autumn from 6 to 8 mg/L. Hypoxic values first appear in May, and low DO value plume can be observed on the bottom in spring along coastal areas of Zhejiang and Fujian Provinces, China. In summer, the plume advances northward, and the hypoxic intensity of northern transects is much higher than southern transects. Until autumn, hypoxia areas fade away little by little, and completely disappear in winter.Within last 50 a, hypoxia in the Changjiang Estuary and its adjacent waters starts to appear in the 1980 s. Since2000, the degree of hypoxia has increased seriously and the distribution depth has become smaller. It is performed based on a large amount of historical data, and the research results will be of great significance to further study on the dynamic development of hypoxia around the Changjiang Estuary. | LU Wenhai XIANG Xianquan YANG Lu XU Yan LI Xiao LIU Shuming | 2017 | Acta Oceanologica Sinica2017，36，5： | 6 |
| 10 | Room-temperature continuous-wave electrically pumped InGaN/GaN quantum well blue laser diode directly grown on Si显示文摘Current laser-based display and lighting applications are invariably using blue laser diodes(LDs)grown on freestanding GaN substrates,which are costly and smaller in size compared with other substrate materials.1–3 Utilizing less expensive and large-diameter Si substrates for hetero-epitaxial growth of indium gallium nitride/gallium nitride(InGaN/GaN)multiple quantum well(MQW)structure can substantially reduce the cost of blue LDs and boost their applications.To obtain a high crystalline quality crack-free GaN thin film on Si for the subsequent growth of a blue laser structure,a hand-shaking structure was formed by inserting Al-composition step down-graded AlN/AlxGa1−xN buffer layers between GaN and Si substrate.Thermal degradation in InGaN/GaN blue MQWs was successfully suppressed with indium-rich clusters eliminated by introducing hydrogen during the growth of GaN quantum barriers(QBs)and lowering the growth temperature for the p-type AlGaN/GaN superlattice optical cladding layer.A continuous-wave(CW)electrically pumped InGaN/GaN quantum well(QW)blue(450 nm)LD grown on Si was successfully demonstrated at room temperature(RT)with a threshold current density of 7.8 kA/cm^(2). | Yi Sun Kun Zhou Meixin Feng Zengcheng Li Yu Zhou Qian Sun Jianping Liu Liqun Zhang Deyao Li Xiaojuan Sun Dabing Li Shuming Zhang Masao Ikeda Hui Yang | 2018 | Light(Science & Applications)2018，7，1： | 5 |

| 12 | A novel layout for single event upset mitigation in advanced CMOS SRAM cells显示文摘A novel layout has been proposed to reduce the single event upset(SEU) vulnerability of SRAM cells.Extensive 3-D technology computer-aided design(TCAD) simulation analyses show that the proposed layout can recover the upset-state much easier than conventional layout for larger space of PMOS transistors.For the angle incidence,the proposed layout is immune from ion hit in two plans,and is more robust against SEU in other two plans than the conventional one.The ability of anti-SEU is enhanced by at least 33% while the area cost reduced by 47%.Consequently,the layout strategy proposed can gain both reliability and area cost benefit simultaneously. | QIN JunRui LI DaWei CHEN ShuMing | 2013 | Science China(Technological Sciences)2013，56，1： | 4 |
| 13 | Effect of microstructure of Au80Sn20 solder on the thermal resistance TO56 packaged GaN-based laser diodes显示文摘Au80Sn20 alloy is a widely used solder for laser diode packaging.In this paper,the thermal resistance of Ga N-based blue laser diodes packaged in TO56 cans were measured by the forward voltage method.The microstructures of Au80Sn20 solder were then investigated to understand the reason for the difference in thermal resistance.It was found that the microstructure with a higher content of Au-rich phase in the center of the solder and a lower content of(Au,Ni)Sn phase at the interface of the solder/heat sink resulted in lower thermal resistance.This is attributed to the lower thermal resistance of Au-rich phase and higher thermal resistance of(Au,Ni)Sn phase. | Hao Lin Deyao Li Liqun Zhang Pengyan Wen Shuming Zhang Jianping Liu Hui Yang | 2020 | Journal of Semiconductors2020，41，10： | 4 |
| 14 | Atom table convolutional neural networks for an accurate prediction of compounds properties显示文摘Machine learning techniques are widely used in materials science.However,most of the machine learning models require a lot of prior knowledge to manually construct feature vectors.Here,we develop an atom table convolutional neural networks that only requires the component information to directly learn the experimental properties from the features constructed by itself.For band gap and formation energy prediction,the accuracy of our model exceeds the standard DFT calculations.Besides,through dataenhanced technology,our model not only accurately predicts superconducting transition temperatures,but also distinguishes superconductors and non-superconductors.Utilizing the trained model,we have screened 20 compounds that are potential superconductors with high superconducting transition temperature from the existing database.In addition,from the learned features,we extract the properties of the elements and reproduce the chemical trends.This framework is valuable for high throughput screening and helpful to understand the underlying physics. | Shuming Zeng Yinchang Zhao Geng Li Ruirui Wang Xinming Wang Jun Ni | 2019 | npj Computational Materials2019，，1： | 4 |
| 15 | Stainless steel corrosion scale formed in reclaimed water: Characteristics, model for scale growth and metal element release显示文摘Stainless steels generally have extremely good corrosion resistance, but are still susceptible to pitting corrosion. As a result, corrosion scales can form on the surface of stainless steel after extended exposure to aggressive aqueous environments. Corrosion scales play an important role in affecting water quality. These research results showed that interior regions of stainless steel corrosion scales have a high percentage of chromium phases. We reveal the morphology, micro-structure and physicochemical characteristics of stainless steel corrosion scales. Stainless steel corrosion scale is identified as a podiform chromite deposit according to these characteristics, which is unlike deposit formed during iron corrosion. A conceptual model to explain the formation and growth of stainless steel corrosion scale is proposed based on its composition and structure. The scale growth process involves pitting corrosion on the stainless steel surface and the consecutive generation and homogeneous deposition of corrosion products, which is governed by a series of chemical and electrochemical reactions. This model shows the role of corrosion scales in the mechanism of iron and chromium release from pitting corroded stainless steel materials. The formation of corrosion scale is strongly related to water quality parameters.The presence of HClO results in higher ferric content inside the scales. Cl-and SO_4^(2-) ions in reclaimed water play an important role in corrosion pitting of stainless steel and promote the formation of scales. | Yong Cui Shuming Liu Kate Smith Hongying Hu Fusheng Tang Yuhong Li Kanghua Yu | 2016 | Journal of Environmental Sciences2016，28，10： | 3 |
| 16 | Modified Tire-Slip-Angle Model for Chaotic Vehicle Steering Motion显示文摘The 5-DOF vehicle model employs the classical tire-slip-angle model to elicit the stability characteristics in vehicle handling during chaotic motion.However,the energy is not conserved,and the simulation results do not match actual behavior in that the vehicle should stop having lost balance.We have analyzed the limitations of the classical tire-slip-angle equation,and developed another model,which can be applied to all conditions.To ensure the correct use of the Pacejka’s magic formula for vehicle dynamics,we discuss the differences in tire axis systems between the ISO and adapted SAE(Pacejka),and propose a transformation method relating the two different tire axis systems.Finally,simulations are described that are performed in accordance with the established 5-DOF vehicle system dynamics model.The simulation results show that all states returned to the stable region after the vehicle had lost balance.The process involved energy dissipation,and approaches the response actually experienced.The limitations of the classical tire-slip-angle model are fully displayed and the effectiveness of the proposed slip angle model is demonstrated in unsteady vehicle states. | Yu Mu Ling Li Shuming Shi | 2018 | Automotive Innovation2018，1，2： | 3 |
| 17 | Fabric changes induced by super-absorbent polymer on cementelime stabilized excavated clayey soil显示文摘This paper studies the microstructure variation induced by super-absorbent polymer(SAP)to understand the mechanism of macroscopic strength improvement of stabilized soil.The fabric changes of cement elime stabilized soil were analyzed with respect to the variation of SAP content,water content,lime content and curing time,using mercury intrusion porosimetry(MIP)tests.It can be observed that the delimitation pore diameter between inter-and intra-aggregate pores was 0.2 mm for the studied soil,determined through the intrusion/extrusion cycles.Experimental results showed that fabric in both inter-and intra-aggregate pores varied significantly with SAP content,lime content,water content and curing time.Two main changes in fabric due to SAP are identified as:(1)an increase in intra-aggregate pores(<0.2 mm)due to the closer soilecementelime cluster space at higher SAP content;and(2)a decrease in inter-aggregate pores represented by a reduction in small-pores(0.2e2 mm)due to the lower pore volume of soil mixture after water absorption by SAP,and a slight increase in large-pores(>2 mm)due to the shrinkage of SAP particle during the freezeedry process of MIP test.Accordingly,the strength gain due to SAP for cementelime stabilized soil was mainly due to a denser fabric with less interaggregate pores.The cementitious products gradually developed over time,leading to an increase in intra-aggregate pores with an increasing proportion of micro-pores(0.006e0.2 mm).Meanwhile,the inter-aggregate pores were filled by cementitious products,resulting in a decrease in total void ratio.Hence,the strength development over time is attributable to the enhancement of cementation bonding and the refinement of fabric due to the increasing cementitious compounds. | Xia Bian Lingling Zeng Xiaozhao Li Xiusong Shi Shuming Zhou Fuqing Li | 2021 | Journal of Rock Mechanics and Geotechnical Engineering2021，13，5： | 3 |
| 18 | Effect of inhomogeneous broadening on threshold current of GaN-based green laser diodes显示文摘The inhomogeneous broadening parameter and the internal loss of green LDs are determined by experiments and theoretical fitting. It is found that the inhomogeneous broadening plays an important role on the threshold current density of green LDs. The green LD with large inhomogeneous broadening even cannot lase. Therefore, reducing inhomogeneous broadening is a key issue to improve the performance of green LDs. | Yipeng Liang Jianping Liu Masao Ikeda Aiqin Tian Renlin Zhou Shuming Zhang Tong Liu Deyao Li Liqun Zhang Hui Yang | 2019 | Journal of Semiconductors2019，40，5： | 3 |
| 19 | A Novel Routing Strategy to Provide Source Location Privacy in Wireless Sensor Networks显示文摘In order to secure the source location privacy when information is sent back to the base station in wireless sensor network, we propose a novel routing strategy which routes the packets to the base station through three stages: directional random routing, h-hop routing in the annular region and the shortest path routing. These stages provide two fold protections to prevent the source location from being tracked down by the adversary. The analysis and simulation results show that proposed scheme, besides providing longer safety period, can significantly reduce energy consumption compared with two baseline schemes. | LI Shuming XIAO Yan LIN Qiaomin QI Zhuzhu | 2016 | Wuhan University Journal of Natural Sciences2016，21，4： | 2 |
| 20 | Review:Chromatic Dispersion Manipulation Based on Optical Metasurfaces显示文摘Metasurfaces are densely arrayed two⁃dimensional(2D)artificial planar metamaterials,which can manipulate the polarization,distribution,and amplitude of light by accurately controlling the phase of the scattering light.The flat metasurface has the potential to substantially reduce the thickness and complexity of the structures and allows ease of fabrication and integration into devices.However,the inherent chromatic aberration of the metasurface originating from the resonant dispersion of the antennas and the intrinsic chromatic dispersion limit their quality.How to effectively suppress or manipulate the chromatic aberration of metalenses has attracted worldwide attention in the last few years,leading to a variety of excellent achievements.Furthermore,utilizing the chromatic dispersion of metasurface to realize special functionalities is also of significant importance.In this review,the most promising recent examples of chromatic dispersion manipulation based on optical metasurface materials are highlighted and put into perspective. | Boyan Fu Xiujuan Zou Tao Li Shuming Wang Zhenlin Wang Shining Zhu | 2020 | Journal of Harbin Institute of Technology(New Series)2020，27，3： | 2 |
