| 1 | Recent advances in graphene-based planar micro-supercapacitors for on-chip energy storage显示文摘The current development trend towards miniaturized portable electronic devices has signiicantly increased the demand for ultrathin, lexible and sustainable on-chip micro-supercapacitors that have enormous potential to complement, or even to replace, micro-bateries and electrolytic capacitors. In this regard,graphene-based micro-supercapacitors with a planar geometry are promising micro-electrochemical energy-storage devices that can take full advantage of planar coniguration and unique features of graphene.his review summarizes the latest advances in on-chip graphene-based planar interdigital micro-supercapacitors, from the history of their development, representative graphene-based materials(graphene sheets, graphene quantum dots and graphene hybrids) for their manufacture, typical microfabrication strategies(photolithography techniques, electrochemical methods, laser writing, etc.),electrolyte(aqueous, organic, ionic and gel), to device coniguration(symmetric and asymmetric). Finally,the perspectives and possible development directions of future graphene-based micro-supercapacitors are briely discussed. | Zhong-Shuai Wu Xinliang Feng Hui-Ming Cheng | 2014 | National Science Review2014，1，2： | 17 |
| 2 | Insulin improves cardiac myocytes contractile function recovery in simulated ischemia-reperfusion:Key role of Akt显示文摘The present study examined cardiac myocytecontractile and Ca2+ transient responses to insulin duringsimulated ischemia/reperfusion (I/R) and furtherinvestigated the role of protein kinase B (Akt) in the insulin-induced inotropic effect. Ventricular myocytes wereenzymatically isolated from adult Sprague-Dawley rats and perfused with Tyrode solution while electrically field-stimulated. Simulated I/R was induced by perfusing the cells with chemical anoxic solution including sodiumcyanide-sodium lactate for 15 min followed by reperfusionwith normal oxygenated Tyrode solution with or withoutinsulin. It is found that insulin only at concentration as high as 10 IU/L could increase cell shortening (16±5%, P < 0.05) in normal myocytes, whereas it concentration-dependently (0.01—10 IU/L) increased the contraction,the velocity ofshortening/releng- thening and Ca2+ transient in I/Rmyocytes. In addition, insulin treatment (1 IU/L) increasedAkt phosphorylation of I/R cardiomyocytes by 2.4-foldcompared with that of the control (P < 0.01). Mostimportantly, pretreatment with LY 294002, a specificinhibitor of phosphatidylinositol 3′-kinase (PI3-kinase), significantly inhibited both Akt phosphorylation and thepositive inotropic response to insulin in the I/Rcardiomyocytes. These results suggest that insulin exertsdirect positive inotropic effect by increasing Ca2+ transient of cardiomyocytes, which is enhanced in the pathologicalcondition of I/R. Akt activation plays an important role inthe insulin-induced improvement of myocyte contractile function following I/R. | ZHANG Bo, ZHANG Haifeng, FAN Qian, MA Xinliang & GAO Feng Department of Physiology, The Fourth Military Medical University,Xi抋n 710032, China Correspondence should be addressed to Gao Feng (e-mail: fgao@fmmu.edu.cn) | 2003 | Chinese Science Bulletin2003，48，13： | 9 |
| 3 | Fault plane parameters of Tancheng M81/2 earthquake on the basis of present-day seismological data显示文摘The great Tancheng earthquake of M81/2 occurred in 1668 was the largest seismic event ever recorded in history in eastern China.This study determines the fault geometry of this earthquake by inverting seismological data of present-day moderate-small earthquakes in the focal area.We relocated those earthquakes with the double-difference method and found focal mechanism solutions using gird test method.The inversion results are as follows:the strike is 21.6°,the dip angle is 89.5°,the slip angle is 170°,the fault length is about 160 km,the lower-boundary depth is about 32 km and the buried depth of upper boundary is about 4 km.This shows that the seismic fault is a NNE-trending upright right-lateral strike-slip fault and has cut through the crust.Moreover,the surface seismic fault,intensity distribution of the earthquake,earthquake-depth distribution and seismic-wave velocity profile in the focal area all verified our study result. | Cuiying Zhou Guiling Diao Jie Geng Yonghong Li Ping Xu Xinliang Hu Xiangdong Feng | 2010 | Earthquake Science2010，23，6： | 7 |

| 6 | Wideband adaptive microwave frequency identification using an integrated silicon photonic scanning filter显示文摘Photonic-assisted microwave frequency identification with distinct features, including wide frequency coverage and fast tunability, has been conceived as a key technique for applications such as cognitive radio and dynamic spectrum access. The implementations based on compact integrated photonic chips have exhibited distinct advantages in footprint miniaturization, light weight, and low power consumption, in stark contrast with discrete optical-fiber-based realization. However, reported chip-based instantaneous frequency measurements can only operate at a single-tone input, which stringently limits their practical applications that require wideband identification capability in modern RF and microwave applications. In this article, we demonstrate, for the first time, a wideband, adaptive microwave frequency identification solution based on a silicon photonic integrated chip,enabling the identification of different types of microwave signals from 1 to 30 GHz, including single-frequency,multiple-frequency, chirped-frequency, and frequency-hopping microwave signals, and even their combinations.The key component is a high Q-factor scanning filter based on a silicon microring resonator, which is used to implement frequency-to-time mapping. This demonstration opens the door to a monolithic silicon platform that makes possible a wideband, adaptive, and high-speed signal identification subsystem with a high resolution and a low size, weight, and power(SWaP) for mobile and avionic applications. | XU WANG FENG ZHOU DINGSHAN GAO YANXIAN WEI XI XIAO SHAOHUA YU JIANJI DONG XINLIANG ZHANG | 2019 | Photonics Research2019，7，2： | 3 |
| 7 | Coarse root spatial distribution determined using a ground-penetrating radar technique in a subtropical evergreen broad-leaved forest,China显示文摘Coarse roots play a critical role in forest ecosystems and both abiotic and biotic factors affect their spatial distribution.To some extent,coarse root density may reflect the quantity of root biomass and biotic competition in forests.However,using traditional methods(e.g.,excavation)to study coarse roots is challenging,because those methods are time-consuming and laborious.Furthermore,these destructive methods cannot be repeated in the same forests.Therefore,the discovery of non-destructive methods for root studies will be very significant.In this study,we used a ground-penetrating radar technique to detect the coarse root density of three habitats(ridge,slope and valley)and the dominant tree species(Castanopsis eyrei and Schima superba)in a subtropical forest.We found that(i)the mean of coarse root density for these three habitats was 88.04roots m–2,with roots being mainly distributed at depths of 0–40 cm.Coarse root densities were lower in deeper soils and in areas far from the trunk.(ii)Coarse root densities differed significantly among the three habitats studied here with slope habitat having the lowest coarse root density.Compared with S.superba,C.eyrei had more roots distributed in deeper soils.Furthermore,coarse roots with a diameter>3 cm occurred more frequently in the valleys,compared with root densities in ridge and slope habitats,and most coarse roots occurred at soil depths of 20–40 cm.(iii)The coarse root density correlated negatively with tree species richness at soil depths of 40–60 cm.The abundances of the dominant species,such as C.eyrei,Cyclobalanopsis glauca,Pinus massoniana,had significant impacts on coarse root density.(iv)The soil depth of 0–40 cm was the'basic distribution layer'for coarse roots since the majority of coarse roots were found in this soil layer with an average root density of 84.18 roots m–2,which had no significant linear relationships with topography,tree species richness,rarefied tree species richness and tree density.Significant relationships between coarse root density and these factors were found at the soil depth of40–60 cm,which was the'potential distribution layer'for coarse root distribution. | YAN Hui DONG XinLiang FENG Gang ZHANG ShouRen MUCCIARDI Anthony | 2013 | Science China(Life Sciences)2013，56，11： | 3 |
| 8 | Broadband on-chip integrator based on silicon photonic phase-shifted Bragg grating显示文摘All-optical integrators are key devices for the realization of ultra-fast passive photonic networks, and, despite their broad applicability range(e.g., photonic bit counting, optical memory units, analogue computing, etc.), their realization in an integrated form is still a challenge. In this work, an all-optical integrator based on a silicon photonic phase-shifted Bragg grating is proposed and experimentally demonstrated, which shows a wide operation bandwidth of 750 GHz and integration time window of 9 ps. The integral operation for single pulse, inphase pulses, and π-shifted pulses with different delays has been successfully achieved. | XU WANG FENG ZHOU SIQI YAN YUAN YU JIANJI DONG XINLIANG ZHANG | 2017 | Photonics Research2017，5，3： | 3 |
| 9 | Vinylene-Linked Two-Dimensional Covalent Organic Frameworks:Synthesis and Functions显示文摘Two-dimensional covalent organic frameworks(2D COFs)with covalently bonded repeat units and crystalline,porous framework backbones have attracted immense attention since the first 2D COFs were reported by Yaghi’s group in 2005.The extended single-layer structures of 2D COFs are also generally considered to be the 2D polymers.The precise incorporation of molecular building blocks into ordered frameworks enables the synthesis of novel organic materials with designable and predictable properties for specific applications,such as in optoelectronics,energy storage,and conversion.In particular,the 2Dπ-conjugated COFs(2D-c-COFs)represent a unique class of 2D conjugated polymers that have 2D molecular-periodic structures with extended in-planeπ-conjugations.In the 2D-c-COFs,the conjugated skeletons andπ−πstacking interactions can provide the pathways for electron transport,while the porous channel can enable the loading of active sites for catalysis and sensing.Thus far,the synthesis of 2D-c-COFs has been mostly limited to Schiff base chemistry based on the condensation reaction between amine and aldehyde/ketone monomers because the construction of 2D COFs as thermodynamically controlled products generally requires a highly reversible reaction for error-correction processes.However,the high reversibility of imine linkages would conversely endow moderateπ-electron delocalization due to the polarized carbon−nitrogen bonds and poor stability against strong acids/bases.To achieve robust and highly conjugated 2D-c-COFs,a series of synthesis strategies have been developed,including a one-step reversible reaction with a bond-forming−bond braking−bond reforming function,a quasi-reversible reaction combing reversible and irreversible processes,and postmodifications converting labile bonds to a robust linkage.Among all of the reported 2D-c-COFs,vinylene-linked(also sp^(2)-carbon-linked)2D covalent organic frameworks(V-2D-COFs)with high in-planeπ-conjugation have attracted increasing interest after we reported the first V-2D-COFs via a Knoevenagel polycondensation in 2016.Although CC bonds have low reversibility,making the synthesis of V-2D-COFs quite challenging,there have been around 40 V-2D-COFs reported over the past 5 years,which demonstrated the merits of V-2D-COFs combining with unique optoelectronic,redox,and magnetic properties.In this Account,we will summarize the development of V-2D-COFs,covering the important aspects of synthesis methods,design strategies,unique physical properties,and functions.First,the solvothermal synthesis of V-2D-COFs using different reaction methodologies and design principles will be presented,including Knoevenagel polycondensation,other aldol-type polycondensations,and Horner−Wadsworth−Emmons(HWE)polycondensation.Second,we will discuss the optoelectronic and magnetic properties of V-2D-COFs.Finally,the promising applications of V-2D-COF in the fields of sensing,photocatalysis,energy storage,and conversion will be demonstrated,which benefit from their robust vinylene-linked skeleton,full in-planeπ-conjugation,and tailorable structures.We anticipate that this Account will provide an intensive understanding of the synthesis of V-2D-COFs and inspire the further development of this emerging class of conjugated organic crystalline materials with unique physicochemical properties and applications across different areas. | Shunqi Xu Marcus Richter Xinliang Feng | 2021 | Accounts of Materials Research2021，2，4： | 2 |

| 15 | Tuning the morphology of chevron-type graphene nanoribbons by choice of annealing temperature显示文摘Bottom-up synthesis of graphene nanoribbons (GNRs) by surface-assisted polymerization and cyclodehydrogenation of specifically designed precursor monomers has been shown to yield precise edges and doping.Here we use a precursor monomer containing sulfur atoms to fabricate nanostructures on a Au(111) surface at different annealing temperatures.The nanostructures have distinct configurations,varying from sulfur-doped polymers to sulfur-doped chevron-type GNRs (CGNRs) and,finally,pristine graphene nanoribbons with specific edges of periodic five-member carbon rings.Non-contact atomic force microscopy provides clear evidence for the cleavage of C-S bonds and formation of pristine CGNRs at elevated annealing temperatures.First-principles calculations show that the CGNRs exhibit negative differential resistance. | Yun Cao Jing Qi Yan-Fang Zhang Li Huang Qi Zheng Xiao Lin Zhihai Cheng Yu-Yang Zhang Xinliang Feng Shixuan Du Sokrates T.Pantelides Hong-Jun Gao | 2018 | Nano Research2018，11，12： | 1 |

| 19 | Insight to the enhanced microwave absorption of porous N-doped carbon driven by ZIF-8:Competition between graphitization and porosity显示文摘Porous carbon-based materials are promised to be lightweight dielectric microwave absorbents.Deeply understanding the influence of graphitization grade and porous structure on the dielectric parameters is urgently required.Herein,utilizing the low boiling point of Zn,porous N-doped carbon was fabricated by carbonization of ZIF-8(Zn)at different temperature,and the microwave absorption performance was investigated.The porous N-doped carbon inherits the high porosity of ZIF-8 precursor.By increasing the carbonization temperature,the contents of Zn and N elements are decreased;the graphitization degree is improved;however,the specific surface area and porosity are increased first and then decreased.When the carbonization temperature is 1000°C,the porous N-doped carbon behaves enhanced microwave absorption.With an ultrathin thickness of 1.29 mm,the ideal RL reaches-50.57 dB at 16.95 GHz and the effective absorption bandwidth is 4.17 GHz.The mechanism of boosted microwave absorption is ascribed to the competition of graphitization and porosity as well as N dopants,resulting in high dielectric loss capacity and good impedance matching.The porous structure can prolong the pathways and raise the contact opportunity between microwaves and porous carbon,causing multiple scattering,interface polarization,and improved impedance matching.Besides,the N dopants can induce electron polarization and defect polarization.These results give a new insight to construct lightweight carbon-based microwave absorbents by regulating the graphitization and porosity. | You Zhou Hongpeng Wang Dan Wang Xianfeng Yang Hongna Xing Juan Feng Yan Zong Xiuhong Zhu Xinghua Li Xinliang Zheng | 2023 | International Journal of Minerals,Metallurgy and Materials2023，30，3： | 1 |
