| 1 | Two-dimensional heterostructure promoted infrared photodetection devices显示文摘It is a rapidly developed subject in expanding the fundamental properties and application of two-dimensional(2D)materials.The weak van der Waals interaction in 2D materials inspired researchers to explore 2D heterostructures(2DHs)based broadband photodetectors in the far-infrared(IR)and middle-IR regions with high response and high detectivity.This review focuses on the strategy and motivation of designing 2DHs based high-performance IR photodetectors,which provides a wide view of this field and new expectation for advanced photodetectors.First,the photocarriers'generation mechanism and frequently employed device structures are presented.Then,the 2DHs are divided into semimetal/semiconductor 2DHs,semiconductor/semiconductor 2DHs,and multidimensional semi-2DHs;the advantages,motivation,mechanism,recent progress,and outlook are discussed.Finally,the challenges for next-generation photodetectors are described for this rapidly developing field. | Gaofeng Rao Xuepeng Wang Yang Wang Peihua Wangyang Chaoyi Yan Junwei Chu Lanxin Xue Chuanhui Gong Jianwen Huang Jie Xiong Yanrong Li | 2019 | InfoMat2019，1，3： | 12 |
| 2 | A mini-review of MXene porous films:Preparation,mechanism and application显示文摘MXene presents excellent electrical conductivity,abundant surface functional groups and wonderful filmforming performance,but the lamellar layers are prone to self-stacking during film formation,which will reduce the loss of electromagnetic waves,hinder ion transmission,and limit the effective load of other functional materials.The construction of the porous structure can effectively solve the self-stacking problem of MXene sheets.This article reviews the research progress of MXene porous films for electromagnetic interference(EMI)shielding,lithium/sodium ion batteries,pseudocapacitors,and biomedical science applications.It focuses on the preparation methods of MXene porous films,and discusses the pore-forming mechanism of the porous structure formed by different preparation methods and the internal relationship between the“microstructure-macroscopic performance”of the MXene porous films,points out the key scientific and technical bottlenecks that need to be solved urgently in the preparation and application of the MXene porous films.It is hoped to provide certain guidance for the design,preparation,optimization,industrial application,and development of MXene porous films. | Yali Zhang Yi Yan Hua Qiu Zhonglei Ma Kunpeng Ruan Junwei Gu | 2022 | Journal of Materials Science & Technology2022，，8： | 9 |
| 3 | Ambient volatile organic compounds at a receptor site in the Pearl River Delta region:Variations,source apportionment and effects on ozone formation显示文摘We present the continuously measurements of volatile organic compounds(VOCs)at a receptor site(Wan Qing Sha,WQS)in the Pearl River Delta(PRD)region from September to November of 2017.The average mixing ratios of total VOCs(TVOCs)was 36.3±27.9 ppbv with the dominant contribution from alkanes(55.5%),followed by aromatics(33.3%).The diurnal variation of TVOCs showed a strong photochemical consumption during daytime,resulting in the formation of ozone(O_(3)).Five VOC sources were resolved by the positive matrix factorization(PMF)model,including solvent usage(28.6%),liquid petroleum gas(LPG)usage(24.4%),vehicle exhaust(21.0%),industrial emissions(13.2%)and gasoline evaporation(12.9%).The regional transport air masses from the upwind cities of south China can result in the elevated concentrations of TVOCs.Low ratios of TVOCs/NO_(x)(1.53±0.88)suggested that the O_(3) formation regime at WQS site was VOC-limited,which also confirmed by a photochemical box model with the master chemical mechanism(PBM-MCM).Furthermore,the observation on high-O_(3) episode days revealed that frequent O_(3) outbreaks at WQS were mainly caused by the regional transport of anthropogenic VOCs especially for aromatics and the subsequent photochemical reactions.This study provides valuable information for policymakers to propose the effective control strategies on photochemical pollution in a regional perspective. | Yao Meng Junwei Song Lewei Zeng Yingyi Zhang Yan Zhao Xufei Liu Hai Guo Liuju Zhong Yubo Ou Yan Zhou Tao Zhang Dingli Yue Senchao Lai | 2022 | Journal of Environmental Sciences2022，34，1： | 5 |
| 4 | Melanin nanoparticles alleviate sepsis-induced myocardial injury by suppressing ferroptosis and inflammation显示文摘Myocardial injury as one of the severe complications leads to the increasing morbidity and mortality in patients with sepsis.Recent studies reported that reactive oxygen species(ROS)-mediated ferroptosis plays a critical role in the development of heart diseases.Therefore,we hypothesized that anti-ferroptosis agent might be a novel potential therapeutic strategy for sepsis-induced cardiac injury.Herein,we demonstrated that a small biocompatible and MRI-visible melanin nanoparticles(MMPP)improves myocardial function by inhibiting ROS-related ferroptosis signaling pathway.In LPS-induced murine sepsis model,after a single dose intravenously injection of MMPP treatment,MMPP markedly alleviated the myocardial injury including cardiac function and heart structure disorder through suppressing iron-accumulation induced ferroptosis.In vitro,MMPP inhibited cardiomyocyte death by attenuating oxidative stress,inflammation and maintaining mitochondrial homeostasis.Collectively,our findings demonstrated that MMPP protected heart against sepsis-induced myocardial injury via inhibiting ferroptosis and inflammation,which might be a novel therapeutic approach in future. | Chang Liu Quan Zou Huixin Tang Jia Liu Shiqi Zhang Caihong Fan Junwei Zhang Ruiqing Liu Yashan Liu Ruiyan Liu Yan Zhao Qiang Wu Zhi Qi Yanna Shen | 2023 | Bioactive Materials2023，，6： | 5 |
| 5 | Effect of surface area and heteroatom of porous carbon materials on electrochemical capacitance in aqueous and organic electrolytes显示文摘A series of porous carbon materials with wide range of specific surface areas and different heteroatom contents had been prepared using polyaniline as carbon precursor and KOH as an activating agent. Effect of surface area and heteroatom of porous carbon materials on specific capacitance was investigated thoroughly in two typical aqueous KOH and organic 1-butyl-3- methylimidazolium tetrafluoroborate/acetonitirle electrolytes. The different trends of capacitance performance were observed in these two electrolytes. Electrochemical analyses suggested that the presence of faradaic interactions on heteroatom-enriched carbon materials in organic environment is less significant than that observed in aqueous electrolytes. Thus, in aqueous electrolyte, a balance between surface area and heteroatom content of activated porous carbon would be found to develop a supercapacitor with high energy density. In organic electrolyte, the capacitance performance of porous carbon is strongly dependent on the surface area. The results may be useful for the design of porous carbon-based supercapacitor with the desired capacitive performance in aqueous and organic electrolytes. | WANG RuTao LANG JunWei YAN XingBin | 2014 | Science China Chemistry2014，57，11： | 4 |

| 7 | Feedback control design with vibration suppression for flexible air-breathing hypersonic vehicles显示文摘This paper investigates the problem of feedback control design with vibration suppression for a flexible air-breathing hypersonic vehicle(FAHV).FAHV includes intricate coupling between the engine and flight dynamics,as well as complex interplay between flexible and rigid modes,which results in an intractable system for the control design.In this paper,a longitudinal model,which is described by a coupled system of ordinary diferential equations(ODEs)and partial diferential equations(PDEs),is adopted.Firstly,a linearized ODE model for the rigid part is established around the trim condition,while vibration of the fuselage is described by PDEs.Secondly,based on the Lyapunov direct method,a control law via ODE state feedback and PDE boundary output feedback is designed for the system such that the closed-loop exponential stability is ensured.Finally,simulation results are given to illustrate the efectiveness of the proposed design method. | GAO Yan WU HuaiNing WANG JunWei GUO Lei | 2014 | Science China(Information Sciences)2014，57，3： | 3 |
| 8 | Early Cretaceous Climate Changes Recorded in Magnetic Susceptibility and Color Index Variations of the Lower Liupanshan Group, Central China显示文摘This study carried out comprehensive analysis on sedimentology, magnetic susceptibility(χlf) and color data of the continental sediments of the Liupanshan Group in Central China so as to obtain climatic change information during the 129.14–122.98 Ma interval. Based on the results of the ?lf and of the redness(a*), the section can be divided into two segments:(1) 129.14–126.3 Ma, with the lowest ?lf values and strongly variable relatively high values of redness and(2) 126.3–122.98 Ma, with high ?lf values and relatively low redness. Analysis of the lithology and facies as well as the magnetic minerals and their contents points to a detrital origin of the magnetic minerals and this allow us to interpret the relationship between magnetic susceptibility variations and climate changes. Our study shows that the climate was significantly dry and hot during the whole studied interval although the interval between 126.3 Ma and 122.98 was a little bit cooler with increased humidity. | DAI Shuang ZHU Qiang HUANG Yongbo DA SILVA Anne-Christine ZHAO Jie LIU Junwei KONG Li PENG Dongxiang LUO Lingling YAN Ningyun WANG Wenjie ZHANG Xiang | 2016 | Acta Geologica Sinica(English Edition)2016，90，3： | 3 |
| 9 | Digital holographic microscopy with phase-shift-free structured illumination显示文摘When structured illumination is used in digital holographic microscopy(DHM),each direction of the illumination fringe is required to be shifted at least three times to perform the phase-shifting reconstruction.In this paper,we propose a scheme for spatial resolution enhancement of DHM by using the structured illumination but without phase shifting.The structured illuminations of different directions,which are generated by a spatial light modulator,illuminate the sample sequentially in the object plane.The formed object waves interfere with a reference wave in an off-axis configuration,and a CCD camera records the generated hologram.After the object waves are reconstructed numerically,a synthetic aperture is performed by an iterative algorithm to enhance the spatial resolution.The resolution improvement of the proposed method is proved and demonstrated by both simulation and experiment. | Juanjuan Zheng Peng Gao Baoli Yao Tong Ye Ming Lei Junwei Min Dan Dan Yanlong Yang Shaohui Yan | 2014 | Photonics Research2014，2，3： | 2 |
| 10 | Key point selection in large-scale FBG temperature sensors for thermal error modeling of heavy-duty CNC machine tools显示文摘Thermal error is one of the main factors that influence the machining accuracy of computer numerical control(CNC)machine tools.It is usually reduced by thermal error compensation.Temperature field monitoring and key temperature measurement point(TMP)selection are the bases of thermal error modeling and compensation for CNC machine tools.Compared with small-and medium-sized CNC machine tools,heavy-duty CNC machine tools require the use of more temperature sensors to measure their temperature comprehensively because of their larger size and more complex heat sources.However,the presence of many TMPs counteracts the movement of CNC machine tools due to sensor cables,and too many temperature variables may adversely influence thermal error modeling.Novel temperature sensors based on fiber Bragg grating(FBG)are developed in this study.A total of 128 FBG temperature sensors that are connected in series through a thin optical fiber are mounted on a heavy-duty CNC machine tool to monitor its temperature field.Key TMPs are selected using these large-scale FBG temperature sensors by using the density-based spatial clustering of applications with noise algorithm to reduce the calculation workload and avoid problems in the coupling of TMPs for thermal error modeling.Back propagation neural network thermal error prediction models are established to verify the performance of the proposed TMP selection method.Results show that the number of TMPs is reduced from 128 to 5,and the developed model demonstrates good prediction effects and strong robustness under different working conditions of the heavy-duty CNC machine tool. | Jianmin HU Zude ZHOU Quan LIU Ping LOU Junwei YAN Ruiya LI | 2019 | Frontiers of Mechanical Engineering2019，14，4： | 2 |

| 12 | Effect of carboxylic acid groups on the supercapacitive performance of functional carbon frameworks derived from bacterial cellulose显示文摘Three-dimensional(3D) carbonaceous materials derived from bacterial cellulose(BC) has been introduced as electrode for supercapacitors in recent. Here, we report a simple strategy for the synthesis of functional carbon frameworks through 2,2,6,6-tetramethylpilperidine 1-oxyl radical(TEMPO)-mediated oxidation of bacterial cellulose(BC) followed by carbonization. TEMPO-mediated oxidation can efficiently convert the hydroxyls on the surface of BC to carboxylate groups to improve electrochemical activity. Because of its high porosity, good hydrophilicity, rich oxygen groups, and continuous ion transport in-between sheet-like porous network, the TEMPO-oxidized BC delivers a much higher gravimetric capacitance(137.3 F/g) at low annealing temperature of 500℃ than that of pyrolysis BC(31 F/g) at the same annealing temperature. The pyrolysis modified BC obtained at 900℃ shows specific capacitance(160.2 F/g), large current stability and long-term stability(84.2% of its initial capacitance retention after 10,000 cycles). | Tianyun Zhang Junwei Lang Li Liu Lingyang Liu Hongxia Li Yipeng Gu Xingbin Yan Xin Ding | 2017 | Chinese Chemical Letters2017，28，12： | 2 |
| 13 | Effects of water deficit and high N fertilization on wheat storage protein synthesis,gluten secondary structure,and breadmaking quality显示文摘The content and composition of wheat storage proteins are the major determinants of dough rheological properties and breadmaking quality and are influenced by cultivation conditions.This study aimed to investigate the effects of water deficit and high N-fertilizer application on wheat storage protein synthesis,gluten secondary structure,and breadmaking quality.Reverse-phase ultrahigh-performance liquid chromatography analysis showed that storage protein and gluten macropolymer accumulation was promoted under both independent applications and a combination of water-deficit and high N-fertilizer treatments.Fourier-transform infrared spectroscopy showed that water deficit and high N-fertilizer treatments generally improved protein secondary structure formation and lipid accumulation,and reduced flour moisture.In particular,high N-fertilizer application increasedβ-sheet content by 10.4%and the combination of water-deficit and high N-fertilizer treatments increased random coil content by 7.6%.These changes in gluten content and secondary structure led to improved dough rheological properties and breadmaking quality,including superior loaf internal structure,volume,and score.Our results demonstrate that moderately high N-fertilizer application under drought conditions can improve gluten accumulation,gluten secondary structure formation,and baking quality. | Junxian Liu Junwei Zhang Gengrui Zhu Dong Zhu Yueming Yan | 2022 | The Crop Journal2022，10，1： | 2 |

| 15 | The roles of graphene in advanced Li-ion hybrid supercapacitors显示文摘Lithium-ion hybrid supercapacitors(LIHSs), also called Li-ion capacitors, are electrochemical energy storage devices that combining the advantages of high power density of supercapacitor and high energy density of Li-ion battery. However, high power density and long cycle life are still challenges for the current LIHSs due to the imbalance of charge-storage capacity and electrode kinetics between capacitor-type cathode and battery-type anode. Therefore, great efforts have been made on designing novel cathode materials with high storage capacity and anode material with enhanced kinetic behavior for LIHSs. With unique two-dimensional form and numerous appealing properties, for the past several years, the rational designed graphene and its composites materials exhibit greatly improved electrochemical performance as cathode or anode for LIHSs. Here, we summarized and discussed the latest advances of the stateof-art graphene-based materials for LIHSs applications. The major roles of graphene are highlighted as(1) a superior active material,(2) ultrathin 2D flexible support to remedy the sluggish reaction of the metal compound anode, and(3) good 2D building blocks for constructing macroscopic 3D porous carbon/graphene hybrids. In addition, some high performance aqueous LIHSs using graphene as electrode were also summarized. Finally, the perspectives and challenges are also proposed for further development of more advanced graphene-based LIHSs. | Junwei Lang Xu Zhang Bao Liu RutaoWang Jiangtao Chen Xingbin Yan | 2018 | Journal of Energy Chemistry2018，27，1： | 2 |
