| 1 | Towards 6G wireless communication networks:vision,enabling technologies,and new paradigm shifts显示文摘The fifth generation(5G)wireless communication networks are being deployed worldwide from 2020 and more capabilities are in the process of being standardized,such as mass connectivity,ultra-reliability,and guaranteed low latency.However,5G will not meet all requirements of the future in 2030 and beyond,and sixth generation(6G)wireless communication networks are expected to provide global coverage,enhanced spectral/energy/cost efficiency,better intelligence level and security,etc.To meet these requirements,6G networks will rely on new enabling technologies,i.e.,air interface and transmission technologies and novel network architecture,such as waveform design,multiple access,channel coding schemes,multi-antenna technologies,network slicing,cell-free architecture,and cloud/fog/edge computing.Our vision on 6G is that it will have four new paradigm shifts.First,to satisfy the requirement of global coverage,6G will not be limited to terrestrial communication networks,which will need to be complemented with non-terrestrial networks such as satellite and unmanned aerial vehicle(UAV)communication networks,thus achieving a space-airground-sea integrated communication network.Second,all spectra will be fully explored to further increase data rates and connection density,including the sub-6GHz,millimeter wave(mmWave),terahertz(THz),and optical frequency bands.Third,facing the big datasets generated by the use of extremely heterogeneous networks,diverse communication scenarios,large numbers of antennas,wide bandwidths,and new service requirements,6G networks will enable a new range of smart applications with the aid of artificial intelligence(AI)and big data technologies.Fourth,network security will have to be strengthened when developing 6G networks.This article provides a comprehensive survey of recent advances and future trends in these four aspects.Clearly,6G with additional technical requirements beyond those of 5G will enable faster and further communications to the extent that the boundary between physical and cyber worlds disappears. | Xiaohu YOU Cheng-Xiang WANG Jie HUANG Xiqi GAO Zaichen ZHANG Mao WANG Yongming HUANG Chuan ZHANG Yanxiang JIANG Jiaheng WANG Min ZHU Bin SHENG Dongming WANG Zhiwen PAN Pengcheng ZHU Yang YANG Zening LIU Ping ZHANG Xiaofeng TAO Shaoqian LI Zhi CHEN Xinying MA Chih-Lin I Shuangfeng HAN Ke LI Chengkang PAN Zhimin ZHENG Lajos HANZO Xuemin(Sherman)SHEN Yingjie Jay GUO Zhiguo DING Harald HAAS Wen TONG Peiying ZHU Ganghua YANG Jun WANG Erik GLARSSON Hien Quoc NGO Wei HONG Haiming WANG Debin HOU Jixin CHEN Zhe CHEN Zhangcheng HAO Geoffrey Ye LI Rahim TAFAZOLLI Yue GAO HVincent POOR Gerhard P.FETTWEIS Ying-Chang LIANG | 2021 | Science China(Information Sciences)2021，64，1： | 122 |

| 3 | High-Chern-number and high-temperature quantum Hall effect without Landau levels显示文摘The quantum Hall effect(QHE)with quantized Hall resistance ofh/ve2 started the research on topological quantum states and laid the foundation of topology in physics.Since then,Haldane proposed the QHE without Landau levels,showing nonzero Chern number|C|=1,which has been experimentally observed at relatively low temperatures.For emerging physics and low-power-consumption electronics;the key issues are how to increase the working temperature and realize high Chern numbers(C>1).Here,we report the experimental discovery of high-Chern-number QHE(C=2)without Landau levels and C=1 Chern insulator state displaying a nearly quantized Hall resistance plateau above the Neel temperature in MnBi2Te4 devices.Our observations provide a new perspective on topological matter and open new avenues for exploration of exotic topological quantum states and topological phase transitions at higher temperatures. | Jun Ge Yanzhao Liu Jiaheng Li Hao Li Tianchuang Luo Yang Wu Yong Xu Jian Wang | 2020 | National Science Review2020，7，8： | 10 |
| 4 | 2D titanium carbide(MXene) electrodes with lower-F surface for high performance lithium-ion batteries显示文摘MXene has shown distinctive advantages as anode materials of lithium-ion batteries. However, local surface chemistry, which was confirmed that can block ion transfer and limit redox reaction, has a significant effect on electrochemical performance. Herein, annealing MXene under hydrogen was employed for removing-F and turning-OH to-O terminations. We demonstrate that it improves the kinetics of Li-ion transport between the electrolyte and electrode. As a result, a lower interfacial charge transfer impedance was obtained. The electrochemical measurement exhibited that a nearly 2-fold increase of specific capacity was achieved for the annealed MXene. | Ming Lu Haojie Li Wenjuan Han Junnan Chen Wen Shi Jiaheng Wang Xiang-Min Meng Jingang Qi Haibo Li Bingsen Zhang Wei Zhang Weitao Zheng | 2019 | Journal of Energy Chemistry2019，28，4： | 8 |
| 5 | Employing MXene as a matrix for loading amorphous Si generated upon lithiation towards enhanced lithium-ion storage显示文摘Although Si-based nanomaterials provide incomparable lithium ion storage ability in theory, it suffers from low initial Coulombic efficiency, electrical disconnection, and fracture due to huge volume changes after extended cycles. As a result, it leads to a severe capacity fading and an increase in internal impedance. Herein, Ti-elemental MXene was employed as a matrix for the intermediate product of Si electrodes. The boundary between the inner core of pristine Si and its outer shell of amorphous Li x Si alloy was reconstructed. Smaller amorphous aggregates were observed in the MXene&Si hybrid electrode after 500 cycles by using transmission electron microscopy. Consequently, an enhanced specific capacity was achieved as MXene as a matrix enables loading amorphous Si. | Haojie Li Ming Lu Wenjuan Han Haibo Li Yucheng Wu Wei Zhang Jiaheng Wang Bingsen Zhang | 2019 | Journal of Energy Chemistry2019，28，11： | 4 |
| 6 | Safe and Stable Lithium Metal Batteries Enabled by an Amide-Based Electrolyte显示文摘The formation of lithium dendrites and the safety hazards arising from flammable liquid electrolytes have seriously hindered the development of high-energy-density lithium metal batteries.Herein,an emerging amide-based electrolyte is proposed,containing LiTFSI and butyrolactam in different molar ratios.1,1,2,2-Tetrafluoroethyl-2,2,3,3-tetrafluoropropylether and fluoroethylene carbonate are introduced into the amide-based electrolyte as counter solvent and additives.The well-designed amide-based electrolyte possesses nonflammability,high ionic conductivity,high thermal stability and electrochemical stability(>4.7 V).Besides,an inorganic/organic-rich solid electrolyte interphase with an abundance of LiF,Li3N and Li-N-C is in situ formed,leading to spherical lithium deposition.The formation mechanism and solvation chemistry of amide-based electrolyte are further inves-tigated by molecular dynamics simulations and density functional theory.When applied in Li metal batteries with LiFePO4 and LiMn2O4 cathode,the amide-based electrolyte can enable stable cycling performance at room temperature and 60℃.This study provides a new insight into the development of amide-based electrolytes for lithium metal batteries. | Wanbao Wu Yiyang Bo Deping Li Yihong Liang Jichuan Zhang Miaomiao Cao Ruitian Guo Zhenye Zhu Lijie Ci Mingyu Li Jiaheng Zhang | 2022 | Nano-Micro Letters2022，14，3： | 2 |
| 7 | Resonance Y-type soliton solutions and some new types of hybrid solutions in the(2+1)-dimensional Sawada–Kotera equation显示文摘In this paper,based on N-soliton solutions,we introduce a new constraint among parameters to find the resonance Y-type soliton solutions in(2+1)-dimensional integrable systems.Then,we take the(2+1)-dimensional Sawada–Kotera equation as an example to illustrate how to generate these resonance Y-type soliton solutions with this new constraint.Next,by the long wave limit method,velocity resonance and module resonance,we can obtain some new types of hybrid solutions of resonance Y-type solitons with line waves,breather waves,high-order lump waves respectively.Finally,we also study the dynamics of these interaction solutions and indicate mathematically that these interactions are elastic. | Jiaheng Li Qingqing Chen Biao Li | 2021 | Communications in Theoretical Physics2021，73，4： | 2 |

| 9 | Association of genetic polymorphisms of GSTM1 and smoking status with lung cancer risk显示文摘Objective Long-term cigarette smoke exposure damages the airway epithelium.However,the correlation among GSTM1 gene polymorphism,smoking status,and lung cancer susceptibility remains unclear.This study aimed to identify the genetic polymorphism of GSTM1 and examine the association of GSTM1 polymorphism and smoking history with lung cancer susceptibility.Methods The genetic polymorphism of GSTM1 was genotyped by polymerase chain reaction(PCR) in 217 lung cancer patients and 198 controls.The demographic data and smoking history of the patients were collected.The age,sex,and residence of the two groups were also obtained.Results Significant differences in GSTM1 polymorphism were observed between the case and control groups(P=0.024).Smoking time and smoking index were significantly different between the case and control groups.With the increase in smoking time and smoking index,the differences became more obvious.There was a synergistic effect between GSTM1 and smoking(S=3.35).The risk of developing lung cancer increased 4.82 fold in smokers carrying deficient-type GSTM1.Compared with patients carrying wild-type GSTM1,the risk of developing lung cancer was higher in those carrying deficient-type GSTM1 with the increase in smoking time and smoking index.In different pathological types,no significant differences were observed in GSTM1 polymorphism.In different pathological types,the proportions of patients increased with the increase in smoking time and smoking index,especially the proportion of patients with squamous cell carcinoma.Compared with wild-type GSTM1,the proportion of patients with deficient-type GSTM1 increased with the increase in smoking time and smoking index(P=0.003 and 0.017).This trend was mainly observed in those with squamous cell carcinoma.Conclusion GSTM1 mutation is associated with lung cancer susceptibility.Smokers carrying deficienttype GSTM1 are more likely to develop lung cancer.Compared with patients carrying wild-type GSTM1,smokers with deficient-type GSTM1 are more likely develop lung cancer when smoking time is more than 30 years and smoking index is more than 400.In patients carrying deficient-type GSTM1,the risk of developing squamous cell carcinoma increases with an increase in smoking time and smoking dose. | Jiaheng Li Lina Zhang Yue Wang Meng Gu Ziyu Wang Weiying Li | 2019 | Oncology and Translational Medicine2019，5，6： | 2 |
| 10 | Fast-convolution multicarrier based frequency division multiple access显示文摘Fast-convolution multicarrier(FCMC), the asynchronous waveform with ultra-low sidelobe, has appeared to be a promising waveform technique for future wireless communications. In this paper, we investigate the filter bank optimization as well as receiver design including low-complexity channel estimator and equalizer for FCMC based frequency division multiple access(FDMA). Starting from the conventional multi-carrier signals, we first derive a vectorized signal model as a framework to systematically design the FCMC transceiver. For nearly perfect reconstruction(NPR) filter banks design, an optimization criterion which consists of minimizing received signal segments’ mean square error(MSE) is proposed. From the fact that Toeplitz matrices can be asymptotically diagonalized by discrete Fourier transform(DFT) matrix, the channel equalizer can be simplified to one-tap frequency domain equalizer when DFT size is large enough.The minimum mean square error(MMSE) criterion is then applied to calculate the coefficients of onetap frequency domain equalizer. In practice, due to the channel fading, the channel estimation has to be performed to obtain the channel state information(CSI) which is required by the channel equalization. To this end, we propose a combined cyclic prefix(CP) and cyclic suffix(CS) pilot structure which facilitates to estimate the frequency domain CSI directly in the receiver end. The proposed FCMC based FDMA features low-complexity receiver, adjustable users’ bandwidth and low peak-to-average power ratio. Simulation results confirm the performance of the proposed scheme. | Yining LI Wenjin WANG Jiaheng WANG Xiqi GAO | 2019 | Science China(Information Sciences)2019，62，8： | 2 |
| 11 | Selenium vacancy-rich and heteroatom-doped CoSe/Mo_(2)CTx MXene prepared using ionic liquid dopants for pH-universal hydrogen evolution and flexible supercapacitors显示文摘Vacancy engineering is a useful methodology in the development of catalysts and electrode materials.Herein,we report the introduction of Se-vacancy pairs in heteroatom-doped(N,B,and F)CoSe/Mo_(2)CT_(x) MXene(NBF-CoSe/Mo_(2)CT_(x))to enhance the hydrogen evolution reaction(HER)and supercapacitor activities via an ionic liquid-mediated method.Se vacancy pairs and heteroatom doping enable the reallocation of local electron states and add active sites,improving the electrochemical activity of NBF-CoSe/Mo_(2)CT_(x) with high HER activities over a broad range of pH.At a current density of 10 mA cm^(-2),overvoltages of 70 and 81 mV are respectively produced in 0.5 M H_(2)SO_(4)and 1 M KOH.The optimal structure also exhibits outstanding electrochemical performance in an asymmetric supercapacitor with an energy density of 34.2 Wh kg^(-1)at a power density of 15989.6Wkg^(-1).This study opens new avenues for the introduction of Se vacancies and heteroatom doping to improve the application performance. | Mingjie Yi Shunyou Hu Na Li Hao Wang Jiaheng Zhang | 2022 | Journal of Energy Chemistry2022，31，9： | 2 |
| 12 | HY5-HDA9 orchestrates the transcription of HsfA2 to modulate salt stress response in Arabidopsis显示文摘Integration of light signaling and diverse abiotic stress responses contribute to plant survival in a changing environment.Some reports have indicated that light signals contribute a plant’s ability to deal with heat,cold,and stress.However,the molecular link between light signaling and the saltresponse pathways remains unclear.We demonstrate here that increasing light intensity elevates the salt stress tolerance of plants.Depletion of HY5,a key component of light signaling,causes Arabidopsis thaliana to become salinity sensitive.Interestingly,the small heat shock protein(sHsp)family genes are upregulated in hy5-215 mutant plants,and HsfA 2 is commonly involved in the regulation of these sH sps.We found that HY5directly binds to the G-box motifs in the HsfA2promoter,with the cooperation of HISTONE DEACETYLASE 9(HDA9),to repress its expression.Furthermore,the accumulation of HDA9 and the interaction between HY5 and HDA9 are significantly enhanced by salt stress.On the contrary,high temperature triggers HY5 and HDA9 degradation,which leads to dissociation of HY5-HDA9from the HsfA2 promoter,thereby reducing salt tolerance.Under salt and heat stress conditions,fine tuning of protein accumulation and an interaction between HY5 and HDA9 regulate HsfA2 expression.This implies that HY5,HDA9,and HsfA2play important roles in the integration of light signaling with salt stress and heat shock response. | Jiaheng Yang Xiao Qu Tao Li Yixiang Gao Haonan Du Lanjie Zheng Manchun Ji Paifeng Zhang Yan Zhang Jinxin Hu Liangyu Liu Zefu Lu Zijian Yang Huiyong Zhang Jianping Yang Yongqing Jiao Xu Zheng | 2023 | Journal of Integrative Plant Biology2023，65，1： | 1 |

| 14 | Crossover from 2D metal to 3D Dirac semimetal in metallic PtTe2 films with local Rashba effect显示文摘PtTe2 and PtSe2 with trigonal structure have attracted extensive research interests since the discovery of type-II Dirac fermions in the bulk crystals. The evolution of the electronic structure from bulk 3D topological semimetal to 2D atomic thin films is an important scientific question. While a transition from 3D type-II Dirac semimetal in the bulk to 2D semiconductor in monolayer(ML) film has been reported for PtSe2, so far the evolution of electronic structure of atomically thin PtTe2 films still remains unexplored.Here we report a systematic angle-resolved photoemission spectroscopy(ARPES) study of the electronic structure of high quality PtTe2 films grown by molecular beam epitaxy with thickness from 2 ML to 6 ML.ARPES measurements show that PtTe2 films still remain metallic even down to 2 ML thickness, which is in sharp contrast to the semiconducting property of few layer PtSe2 films. Moreover, a transition from 2D metal to 3D type-II Dirac semimetal occurs at film thickness of 4–6 ML. In addition, Spin-ARPES measurements reveal helical spin textures induced by local Rashba effect in the bulk PtTe2 crystal, suggesting that similar hidden spin is also expected in few monolayer PtTe2 films. Our work reveals the transition from2D metal to 3D topological semimetal and provides new opportunities for investigating metallic 2D films with local Rashba effect. | Ke Deng Mingzhe Yan Chu-Ping Yu Jiaheng Li Xue Zhou Kenan Zhang Yuxin Zhao Koji Miyamoto Taichi Okuda Wenhui Duan Yang Wu Xiaoyan Zhong Shuyun Zhou | 2019 | Science Bulletin2019，64，15： | 1 |

| 16 | Distribution of antibiotic resistance genes and their association with bacteria and viruses in decentralized sewage treatment facilities显示文摘The distribution of antibiotic resistance genes(ARGs)has been intensively studied in large-scale wastewater treatment plants and livestock sources.However,small-scale decentralized sewage treatment facilities must also be explored due to their possible direct exposure to residents.In this study,six wastewater treatment facilities in developed rural areas in eastern China were investigated to understand their risks of spreading ARGs.Using metagenomics and network analysis tools,ARGs and bacterial and viral communities were identified in the influent(INF)and effluent(EFF)samples.The dominant ARGs belonged to the bacitracin class,which are different from most of municipal wastewater treatment plants(WWTPs).The dominant hosts of ARGs are Acidovorax in bacterial communities and Prymnesiovirus in viral communities.Furthermore,a positive relationship was found between ARGs and phages.The ARGs significantly correlated with phages were all hosted by specific genera of bacteria,indicating that phages had contributed to the ARG’s proliferation in sewage treatment facilities.Paying significant concern on the possible enhanced risks caused by bacteria,viruses and their related ARGs in decentralized sewage treatment facilities is necessary. | Jiaheng Zhao Bing Li Pin Lv Jiahui Hou Yong Qiu Xia Huang | 2022 | Frontiers of Environmental Science & Engineering2022，16，3： | 1 |
| 17 | Pressure-induced Lifshitz transition in the type Ⅱ Dirac semimetal PtTe_2显示文摘Numerous exotic properties have been discovered in Dirac Semimetals(DSMs) and Weyl Semimetals(WSMs). In a given DSM/WSM, the Dirac/Weyl nodes usually coexist with other bulk states, making their respective contribution elusive. In this work, we distinguish the role of bulk states from the tilted Dirac nodes on the transport properties in DSMs. Specifically, we applied pressure to a type-II DSM material, PtTe2, and studied its pressure modified electronic and lattice structure systematically by using in situ transport measurements and X-ray diffraction(XRD). A pressure-induced transition at about 20 GPa is revealed in the transport properties, while the layered lattice structure is robust against pressure as illustrated in XRD measurement results.Density functional theory(DFT) calculations suggest that this is originated from the Lifshitz transition in the bulk states. Our findings provide evidence to identify the bulk states' influence on transport from the topologically-protected DSM states in the DSM material. | FengLiang Liu JiaHeng Li KeNan Zhang Shang Peng HuaQing Huang MingZhe Yan NaNa Li Qian Zhang SongHao Guo XuJie Lü Peng Cai LiFeng Yin ShuYun Zhou WenHui Duan Jian Shen WenGe Yang | 2019 | Science China(Physics,Mechanics & Astronomy)2019，62，4： | 1 |

| 19 | Floating Escherichia coli by Expressing Cyanobacterial Gas Vesicle Genes显示文摘Gas vesicles are hollow, air-filled polyprotein structures that provide the buoyancy to cells. They are found in a variety of prokaryotes. In this study, we isolated a partial gas vesicle protein gene cluster containing gvp A and gvp C20Ψ from Planktothrix rubescens, and inserted it into an expression vector and expressed it in E. coli. The gas vesicle was developed in bacterial cells, which made bacterial cells to float on medium surface. We also amplified gvp A and gvp C20Ψ separately and synthesized an artificial operon by fusing these two genes with the standardized gene expression controlling elements of E. coli. The artificial operon was expressed in E. coli, forming gas vesicles and floating bacteria cells. Our findings verified that the whole set of genes and the overall structure of gas vesicle gene cluster are not necessary for developing gas vesicles in bacteria cells. Two genes, gvp A and gvp C20Ψ, of the gas vesicle gene cluster are sufficient for synthesizing an artificial operon that can develop gas vesicles in bacteria cells. Our findings provided a wide range of applications including easing the harvest of cultured microalgae and bacteria, as well as enriching and remediating aquatic pollutants by constructing gas vesicles in their cells. | WANG Tianhe KANG Li LI Jiaheng WU Wenjie ZHANG Peiran GONG Minghao LAI Weihong ZHANG Chunyan CHANG Lei PENG Yong YANG Zhongzhou LI Lian BAO Yingying XU Haowen ZHANG Xiaohua SUI Zhenghong YANG Guanpin WANG Xianghong | 2015 | Journal of Ocean University of China2015，14，1： | 1 |
