| 2 | Serum IgA,IgM,and IgG responses in COVID-19显示文摘Currently,detecting SARS-CoV-2 RNAs is a standard approach for COVID-19 diagnosis.However,there is an urgent need for reliable and rapid serological diagnostic methods to screen SARS-CoV-2-infected people including those who do not have overt symptoms.Most emerging studies described serological tests based on detection of SARS-CoV-2-specific IgM and IgG.1–4 Although detection of SARS-CoV-2-specific IgA in serum has been reported in few papers,5,6 analyses of IgA levels in a larger number of COVID-19 patients are still lacking. | Huan Ma Weihong Zeng Hongliang He Dan Zhao Dehua Jiang Peigen Zhou Linzhao Cheng Yajuan Li Xiaoling Ma Tengchuan Jin | 2020 | Cellular & Molecular Immunology2020，17，7： | 12 |
| 3 | From structural ceramics to 2D materials with multi-applications:A review on the development from MAX phases to MXenes显示文摘MAX phases(Ti_(3)SiC_(2),Ti_(3)AIC_(2),V_(2)AlC,TiqAlN_(3),etc.)are layered ternary carbides/nitrides,which are generally processed and researched as structure ceramics.Selectively removing A layer from MAX phases,MXenes(Ti_(3)C_(2),V_(2)C,Mo_(2)C,etc.)with two-dimensional(2D)structure can be prepared.The MXenes are electrically conductive and hydrophilic,which are promising as functional materials in many areas.This article reviews the milestones and the latest progress in the research of MAX phases and MXenes,from the perspective of ceramic science.Especially,this article focuses on the conversion from MAX phases to MXenes.First,we summarize the microstructure,preparation,properties,and applications of MAX phases.Among the various properties,the crack healing properties of MAX phase are highlighted.Thereafter,the critical issues on MXene research,including the preparation process,microstructure,MXene composites,and application of MXenes,are reviewed.Among the various applications,this review focuses on two selected applications:energy storage and electromagnetic interference shielding.Moreover,new research directions and future trends on MAX phases and MXenes are also discussed. | Aiguo ZHOU Yi LIU Shibo LI Xiaohui WANG Guobing YING Qixun XIA Peigen ZHANG | 2021 | Journal of Advanced Ceramics2021，10，6： | 4 |
| 4 | Experimental investigations of granular shape effects on the generation of electrostatic charge显示文摘In solid processing systems,electrostatic problems are commonly observed for granules of various shapes.However,a complete understanding of the basic dependence of electrostatic charge generation on particle shape has yet to be established.This observation motivated the present study on examining the effect of granular shape on electrostatics.In this study,polyvinyl chloride(PVC) granules(diameter 1.1-4.1 mm,in the shape of a triangle or trapezium) were first discharged to remove any residual charges and subsequently their electrostatic charging characteristics were studied by allowing a granule to slide along a pipe wall.Several factors such as granular front-facing angle,length-ratio,sliding area,sliding orientation,sliding times,and relative humidity were considered when studying their effects on the electrostatic charging of granules.It was found that triangular granules with smaller front-facing angles tended to generate more electrostatic charge.The amount of electrostatic charge increased with granular lengthratio and sliding area but decreased with humidity.In addition,granular sliding in the orientation of the front-facing angle(for triangular granules) or the short side(for trapezoidal granules) generated more electrostatic charge than that in the orientation of the long side.For both granule shapes,the electrostatic charge increased with granular sliding times and reached a saturated state after around 8-9 sliding movements.The saturated electrostatic charge increased with either granular length ratio or sliding area. | Jun Yao Jiejie Wu Yanlin Zhao Eldin Wee Chuan Lim Peigen Cao Fang Zhou Chi-Hwa Wang Ning Li | 2014 | Particuology2014，12，4： | 2 |
| 5 | A Low Power,High Sensitivity SiGe HBT Static Frequency Divider up to 90 GHz for Millimeter-Wave Application显示文摘A layout and connection optimization for static frequency divider is presented. The layout optimization provides a new circle topology transistors placement and reasonable connection structure, which reduces the parasitic effectively and enables self-oscillation frequency enhancement. Besides, bandwidth enhancement techniques based on a center-tap capacitor in input balun design and inductive peaking in latch design are adopted to improve further high frequency performance with low power consumption. As a proof of concept, design of a divide-by-2 static frequency divider in 0.13 μm SiGe BiCMOS technology is reported. With single-ended input clock signal, the divider is measured to be operated from 40 to 90 GHz. Phase noise measurements of a 90 GHz input clock signal indicate ideal behavior with no measurable noise contribution from the divider. The divider followed by a buffer that can deliver more than-10 dBm output power, which is sufficient to drive succeeding stage. To the author's knowledge, the divider exhibits a competitive power dissipation and the highest FOM among silicon based frequency dividers that operating higher than 70 GHz. | Peigen Zhou Jixin Chen Pinpin Yan Debin Hou Wei Hong | 2019 | China Communications2019，16，2： | 2 |

| 11 | Tin whiskers prefer to grow from the [001] grains in a tin coating on aluminum substrate显示文摘This work aims at understanding the features of the Sn grains from which whiskers prefe rentially grow.The growth behavior of Sn whiskers on a 50 μm thick hypereutectic Sn-Al alloy coating was observed in situ by mapping the grain orientations before and after aging using the electron backscatter diffraction(EBSD) technique.Sn whiskers were found to grow preferentially from the(001) or near-(001) grains surrounded by the grains having perpendicular orientations,such as(100),(110) and(210).The compre s sive stress in the coating was heterogeneous,and the(001) grains exhibited the higher compressive stress close to the grain boundaries.The orientation relationship between α-Al phase and β-Sn phase was confirmed as(200)_(α-A)||(200)_(β-Sn,[011]_(α-A)||[001]_(β-Sn).The plane matching resulted in approximately0.7 % misfit strain in β-Sn,which had little impact on the growth of whiskers.Dislocations pile-ups were found in the(001) grains and repulsed by the Sn oxide layer,giving the probability of cracking the oxide.Grain boundaries were found between the whisker and underneath grain.The dominant diffusion mode for early whisker growth was grain boundary diffusion aided by pipe diffusion. | Shuang Tian Yushuang Liu Peigen Zhang Jian Zhou Feng Xue ZhengMing Sun | 2021 | Journal of Materials Science & Technology2021，，21： | 0 |
| 12 | Research on Silicon-Based Terahertz Communication Integrated Circuits显示文摘With the increasing number of users and emerging new applications, the demand for mobile data traffic is growing rapidly. The limited spectrum resources of the traditional microwave and millimeter-wave frequency bands can no longer support the future wireless communication systems with higher system capacity and data throughput. The terahertz(THz) frequency bands have abundant spectrum resources, which can provide sufficient bandwidth to expand channel capacity and increase transmission data rate. In addition, with the rapid development of silicon-based semiconductor technology,its characteristic size keeps decreasing, and the radio frequency performance of active devices is gradually approaching the performance of III-V semiconductor technology. The realization of THz communication systems based on low-cost, high-stability, and easy-to-integrate silicon-based process has become a feasible solution. This review summarizes the reported silicon-based THz communication systems, as well as the key sub-circuit chips in these systems, including the local oscillator, power amplifier, low noise amplifier, on-chip antenna and transceiver chip, etc. | ZHOU Peigen CHEN Jixin TANG Siyuan YU Jiayang WANG Chen LI Huanbo LU Haiyan YAN Pinpin HOU Debin CHEN Zhe HONG Wei | 2022 | Chinese Journal of Electronics2022，31，3： | 0 |

| 14 | A SiGe W-band frequency tripler with 10.5 dBm output power using harmonic suppression technique显示文摘Dear editor,The rapid development of silicon-based process has motivated great attention in mm-wave applications.Recently,W-band frequencies have become an appealing choice for various wireless applications,such as automotive radar,high data-rate communication,and high resolution imaging.There are two traditional methods to generate local oscillator(LO)singals,implementing voltage-controlled oscillators(VCOs)operating at the desired frequencies directly or low-frequency VCOs followed with a multiplier chain[1–5].The second scheme is more attractive in W-band frequencies for it can relax the designing challenge of the VCO and improve the phase noise. | Huanbo LI Jixin CHEN Peigen ZHOU Debin HOU Wei HONG | 2022 | Science China(Information Sciences)2022，65，4： | 0 |
| 15 | Decline of SARS-CoV-2-specific IgG,IgM and IgA in convalescent COVID-19 patients within 100 days after hospital discharge显示文摘Dear editor,The 2019 novel coronavirus(later renamed as SARS-CoV-2 in February 2020)infected over 12 million people globally by early July 2020,causing mild to severe COVID-19 in millions.Monitoring the levels of antibodies such as immunoglobin(Ig)G,M and A that are specific to SARS-CoV-2 and present in the blood provides not only an alternative method for diagnosing SARS-CoV-2 infection(including asymptomatic carriers),but also a simple way to monitor immune responses in convalescent patients or after vaccination.A high and persistent level of antibodies specific to SARS-CoV-2,especially those that can bind to and neutralize the virus,would be a strong indication that an immunized host could resist to SRAS-CoV-2 infection.Currently,there are no effective drugs to specifically prevent or cure SARS-CoV-2 infection;therefore,host immune responses and antibody-based therapeutics will continue to play important roles in combating and later preventing COVID-19. | Huan Ma Dan Zhao Weihong Zeng Yunru Yang Xiaowen Hu Peigen Zhou Jianping Weng Linzhao Cheng Xueying Zheng Tengchuan Jin | 2021 | Science China(Life Sciences)2021，64，3： | 0 |
| 16 | Research Towards Terahertz Power Amplifiers in Silicon-Based Process显示文摘In view of the existing design challenges for Terahertz(THz)power amplifiers(PAs),the common design methods and the efforts of the State Key Laboratory of Millimeter Wave,Southeast University,China in the development of silicon-based THz PAs,mainly including silicon-based PAs with operating frequencies covering 100–300 GHz,are summarized in this paper.Particularly,we design an LC-balun-based two-stage differential cascode PA with a center frequency of 150 GHz and an output power of 14 dBm.Based on a Marchand balun,we report a 220 GHz three-stage differential cascode PA with a saturated output power of 9.5 dBm.To further increase the output power of THz PA,based on a four-way differential power combining technique,we report a 211–263 GHz dual-LC-tank-based broadband PA with a recorded 14.7 dBm Psat and 16.4 dB peak gain.All the above circuits are designed in a standard 130 nm silicon germanium(SiGe)BiCMOS process. | CHEN Jixin ZHOU Peigen YU Jiayang LI Zekun LI Huanbo PENG Lin | 2023 | ZTE Communications2023，21，2： | 0 |
| 17 | A two-dimensional tetragonal structure of vanadium telluride显示文摘The family of vanadium chalcogenides with variable stoichiometry and abundant crystallographic structures are promising platforms for realizing exotic emergent phenomena.Here,we report on a novel two-dimensional(2D)tetragonal structure of vanadium telluride(VTe)grown by molecular beam epitaxy.The atomic structures and electronic properties are revealed by scanning tunneling microscopy and first-principles calculations.Different from the hexagonal or trigonal lattices of 2D VTe_(2),the 2D VTe with a V:Te ratio of 1:1 exhibits an uncommon square lattice.Non-zero differential conductivity at the Fermi energy detected by scanning tunneling spectroscopy reveals the metallic feature of VTe.Meanwhile,Friedel oscillations are observed near chiral point defects and domain walls,illustrating the itinerant nature of the electrons close to the Fermi energy.Our firstprinciples structure searches identify a 2D body-centered cubic(bcc)-like structure with a favorable formation energy to be the candidate of the metallic phase of the tetragonal VTe obtained experimentally.Based on our calculations the 2D bcc-like structure possesses a strong 2D antiferromagnetic order.Our work enriches the family of vanadium chalcogenides and provides a possible 2D antiferromagnetic material for fabricating advanced spintronic devices. | Zizhao Liu Ye Tao Zhiqiang Cui Yi Ji Xuhan Zhou Peigen Li Yunwei Zhang Dingyong Zhong | 2023 | Nano Research2023，16，5： | 0 |
