3Graphene TiO_2 nanocomposites with high photocatalytic activity for the degradation of sodium pentachlorophenol显示文摘A series of graphene–TiO2photocatalysts was synthesized by doping TiO2 with graphene oxide via hydrothermal treatment. The photocatalytic capability of the catalysts under ultraviolet irradiation was evaluated in terms of sodium pentachlorophenol(PCP-Na) decomposition and mineralization. The structural and physicochemical properties of these nanocomposites were characterized by X-ray diffraction, N2adsorption–desorption, transmission electron microscopy, scanning electron microscopy, Ultraviolet–visible diffuse reflectance spectroscopy, X-ray photoelectron spectroscopy, electron paramagnetic resonance spectra, and Fourier-transform infrared spectroscopy. The graphene–TiO2nanocomposites exhibited higher photocatalytic efficiency than commercial P25 for the degradation of PCP-Na, and 63.4% to 82.9% of the total organic carbon was fully mineralized. The improved photocatalytic activity may be attributed to the accelerated interfacial electron-transfer process and the significantly prolonged lifetime of electron-hole pairs imparted by graphene sheets in the nanocomposites. However,excessive graphene and the inhomogeneous aggregation of TiO2 nanoparticles may decrease photodegradation efficiency.Yaxin Zhang Zeyu Zhou Tan Chen Hongtao Wang Wenjing Lu 2014Journal of Environmental Sciences2014,26,10:6
4Global structures of the DE3 tide显示文摘The Hough mode decomposition (HMD) is used to investigate the global structures of the eastward propagating diurnal tide of zonal wavenumber 3 (DE3). The tide is delineated by using the SABER/ TIMED temperatures collected during 2002―2006. The HMD analysis results show that the DE3 tide is primarily dominated by two leading propagating Hough modes, i.e., (-3, 3) and (-3, 4) modes; the in-fluences .of the other Hough modes including trapped modes can be neglected. Based upon the HMD analysis results, this paper first reported the maximum of the tidal activity in the MLT region. The re-sults show that the DE3 tide exhibits annual unimodal distribution with the maximal amplitude occur-ring at 110 km in late summer (around July each year). Moreover, characteristic 2-year period variation is observed in the (-3, 3) Hough mode. And this type of inter-annual variation is further reflected in the tidal amplitude at 110 km height. For example, corresponding to the 2-year variation of the (-3, 3) mode, the DE3 tidal amplitude exhibits two substantially enhanced activities with maximal amplitude exceed-ing 12 K in 2002 and 2004, respectively. Moreover, current investigation results indicate that the influ-ence of the second propagating Hough mode, (-3, 4) mode, is important, in particular at the height un-der 100 km, where the DE3 amplitudes exhibit antisymmetric distribution with respect to the equator. The (-3, 4) mode exhibits bimodal distribution over a yearly course, which dominates the DE3 tide in the lower mesosphere. For example, two maximal DE3 activities were observed in late-winter-to-early- spring and late-autumn-to-early-winter, respectively. The first maximum is seen in the south of the equator, and the second maximum is in the north of it.CHEN ZeYu LU DaRen 2009Chinese Science Bulletin2009,54,6:4
5基于界面改性的碳纳米管增强水泥基复合材料力学性能与机理研究显示文摘为研究界面改性的碳纳米管(CNTs)增强水泥基复合材料力学性能与机理,用酸处理CNTs的表面,并采用聚乙烯醇(PVA)作为桥联剂改善CNTs与水泥基体间的界面,首先采用XPS光谱、FTIR测试及ToF-SIMS质谱法评价CNTs的表面处理和界面结合情况,然后对比分析了水泥/PVA、水泥/a-CNTs、水泥/PVA/a-CNTs和水泥/PVA/CNTs复合材料的力学性能测试结果。结果表明:CNTs通过表面处理可以得到有效官能团,从而增强和水泥之间的连接,PVA的加入也可以有效改善CNTs与水泥的结合程度;未经处理的原始CNTs对水泥复合材料的抗折强度增强效果不明显,而含有PVA和经表面处理的CNTs的水泥复合材料,其抗折强度显著增加,可从5.52 MPa增加到12.61 MPa。研究证明,通过强化CNTs和水泥基体之间的界面,可以明显增强水泥/CNTs复合材料的力学性能。邵玉 杨哲 邢明亮 孙岳 陈华鑫 Guoxing Sun Rui Liang Zeyu Lu 2018中外公路2018,38,1:2
6The Corylus mandshurica genome provides insights into the evolution of Betulaceae genomes and hazelnut breeding显示文摘Hazelnut is popular for its flavor,and it has also been suggested that hazelnut is beneficial to cardiovascular health because it is rich in oleic acid.Here,we report the first high-quality chromosome-scale genome for the hazelnut species Corylus mandshurica(2n=22),which has a high concentration of oleic acid in its nuts.The assembled genome is 367.67Mb in length,and the contig N50 is 14.85 Mb.All contigs were assembled into 11 chromosomes,and 28,409 protein-coding genes were annotated.We reconstructed the evolutionary trajectories of the genomes of Betulaceae species and revealed that the 11 chromosomes of the hazelnut genus were derived from the most ancestral karyotype in Betula pendula,which has 14 protochromosomes,by inferring homology among five Betulaceae genomes.We identified 96 candidate genes involved in oleic acid biosynthesis,and 10 showed rapid evolution or positive selection.These findings will help us to understand the mechanisms of lipid synthesis and storage in hazelnuts.Several gene families related to salicylic acid metabolism and stress responses experienced rapid expansion in this hazelnut species,which may have increased its stress tolerance.The reference genome presented here constitutes a valuable resource for molecular breeding and genetic improvement of the important agronomic properties of hazelnut.Ying Li Pengchuan Sun Zhiqiang Lu Jinyuan Chen Zhenyue Wang Xin Du Zeyu Zheng Ying Wu Hongyin Hu Jiao Yang Jianxiang Ma Jianquan Liu Yongzhi Yang 2021Horticulture Research2021,8,1:1
7Squeezing bandwidth controllable twin beam light and phase sensitive nonlinear interferometer based on atomic ensembles显示文摘We review our recent experimental progress in quantum technology employing amplification effect of four-wave mixing in a rubidium vapor. We have produced an intensity difference squeezed light source at frequencies as low as 1.5 kHz which is so far the lowest frequency at which squeezing has been observed in an atomic system. Moreover, we find that the bandwidth of our squeezed light source can be controlled with light intensity pumping. Using our non-classical light source, we have further developed a nonlinear Mach-Zehnder (MZ) interferometer, for which the maximum fringe intensity depends quadratically on the intensity of the phase-sensing field at the high-gain regime, leading to much better sensitivity than a linear MZ interferometer in which the beam splitters have the same phase-sensing intensity. The quantum technologies developed by our group could have great potential in areas such as precision measurement and quantum information.JING JieTai LIU CunJin ZHOU ZhiFan HUDELIST Florian YUAN ChunHua CHEN LiQing LI XiaoYun QIAN Jing ZHANG KeYe ZHOU Lu MA HongMei DONG GuangJiong OU ZeYu ZHANG WeiPing 2012Chinese Science Bulletin2012,57,16:1

10The collaboration between infectious disease modeling and public health decision-making based on the COVID-19显示文摘Public health decision-making may have great uncertainty especially in dealing with emerging infectious diseases,so it is necessary to establish a collaborative mechanism among modelers,epidemiologists,and public health decision-makers to reduce the uncertainty as much as possible.We searched the relevant studies on transmission dynamics modeling of infectious diseases,SARS,MERS,and COVID-19 as of March 1,2021 based on PubMed.We compared the key health decision-making time points of SARS,MERS,and COVID-19 prevention and control,and the publication time points of modeling research,to reveal the collaboration between infectious disease modeling and public health decision-making in the context of the COVID-19 pandemic.Searching with infectious disease and mathematical model as keywords,there were 166,81 and 1289 studies on the modeling of infectious disease transmission dynamics of SARS,MERS,and COVID-19 were retrieved respectively.Based on the modeling application framework of public health practice proposed in the current study,the collaboration among modelers,epidemiologists and public health decision-makers should be strengthened in the future.Yan Niu Zhuoyang Li Ling Meng Shengnan Wang Zeyu Zhao Tie Song Jianhua Lu Tianmu Chen Qun Li Xuan Zou 2021Journal of Safety Science and Resilience2021,2,2:1
11Issues and strategies of cathode materials for mild aqueous static zinc-ion batteries显示文摘Researchers prefer mild aqueous static zinc-ion batteries(ASZIBs)for their distinct benefits of excellent safety,abundant zinc resources,low cost,and high energy density.However,at the moment there are some issues with the cathode materials of mild ASZIBs,including dissolution,by-products,poor conductivity,and a contentious energy storage system.Consequently,there are numerous difficulties in the development of high-performance mild ASZIBs cathode materials.This overview examines the mechanisms for storing energy and the de-velopments in inorganic,organic,and other novel cathode materials that have emerged in recent years.At the same time,three solutions—structural engineering,interface engineering,and reaction pathway engineering—as well as the difficulties now faced by the cathode materials of mild ASZIBs are forcefully introduced.Finally,a prospect is made regarding the evolution of cathode materials in the future.Wei Zhong Jiahui Zhang Zongmiao Li Zeyu Shen Shichao Zhang Xinyang Wang Yingying Lu 2023Green Chemical Engineering2023,4,3:0

Results reveal that many of them display considerable in vitro antitubercular activity. Four N-benzyl or N- (pyridine-2-yl)methyl 3,5-dinitrobenzamides A6, All, Cl and C4 have not only the same excellent MIC values of<0.016 μg/mL against both drug-sensitive MTB strain H37 Rv and two drug-resistant clinical isolates as PBTZ169 and the lead 1, but also acceptable safety indices (SI > 1500), opening a new direction for further development.Hongjian Wang Kai Lv Xiaoning Li Bo Wang Apeng Wang Zeyu Tao Yunhe Geng Bin Wang Menghao Huang Mingliang Liu Huiyuan Guo Yu Lu 2019Chinese Chemical Letters2019,30,2:0
13Characterization of road surfacing aggregates based on their mineralogical fingerprint显示文摘To ensure the safety of infrastructure users,the long-term skid resistance is a crucial factor and is determined in large by the mineralogical and morphological characteristics of surfacing aggregate.Most studies have investigated these aggregate properties separately without considering the interrelation between one another.The objective of this study is to consider the morphological characteristics as well as the mineralogical fingerprint of aggregate to develop an innovative approach to optimize the aggregate selection process.The investigations are based on 11 different aggregate types with a broad range of mineralogy,commonly used in Germany.The long-term influence of polishing and wearing on the surface aggregate was simulated by means of the Aachen Polishing Machine and the MicroDeval test respectively.To evaluate the impact of these tests,the aggregate shape was characterized by means of an imaging system called Aggregate Image Measurement System while the skid resistance of aggregates was evaluated with the British Pendulum Test.The test results show that the quartz and calcite are the key crystals to determine the anti-wear resistance of aggregates.A correlation between the skid resistance,morphological properties and mineralogy is derived,which proves the mineralogical fingerprint technology is practical for characterization of aggregates used in pavement surface layers.Dawei Wang Yulin He Chonghui Wang Zeyu Zhang Guoyang Lu Pengfei Liu Markus Oeser 2022Journal of Traffic and Transportation Engineering(English Edition)2022,9,5:0

15Regulation of the activity,selectivity,and durability of Cu-based electrocatalysts for CO_(2) reduction显示文摘CO_(2)electroreduction offers a promising approach to alleviate global warming and reduce petroleum consumption simultaneously,due to its capability to convert the greenhouse gas CO_(2)to valuable fuels and chemicals by using renewable electricity.Electrocatalyst has an essential impact on the CO_(2)electroreduction performance.Among the diverse exploited materials,Cu is the only monometallic electrocatalyst that can produce CO and hydrocarbons.However,its activity,selectivity,and durability are not satisfactory for practical applications.Here,we make a comprehensive survey of the recent progress in enhancing Cu-based electrocatalysts with the strategies such as oxidation pre-treatment,heteroatom doping,morphological control,and surface modification.This review provides an overview of the current status and future opportunities for Cu-catalyzed CO_(2)electroreduction.It may contribute to the rational design of Cu-based electrocatalysts with improved performance and thus advance practical CO_(2)electrolyzer development.Chang Liu Jun Gong Zeyu Gao Li Xiao Gongwei Wang Juntao Lu Lin Zhuang 2021Science China Chemistry2021,64,10:0
16Small-molecule agents for cancer immunotherapy显示文摘Cancer immunotherapy,exemplified by the remarkable clinical benefits of the immune checkpoint blockade and chimeric antigen receptor T-cell therapy,is revolutionizing cancer therapy.They induce long-term tumor regression and overall survival benefit in many types of cancer.With the advances in our knowledge about the tumor immune microenvironment,remarkable progress has been made in the development of small-molecule drugs for immunotherapy.Small molecules targeting PRR-associated pathways,immune checkpoints,oncogenic signaling,metabolic pathways,cytokine/chemokine signaling,and immune-related kinases have been extensively investigated.Monotherapy of smallmolecule immunotherapeutic drugs and their combinations with other antitumor modalities are under active clinical investigations to overcome immune tolerance and circumvent immune checkpoint inhibitor resistance.Here,we review the latest development of small-molecule agents for cancer immunotherapy by targeting defined pathways and highlighting their progress in recent clinical investigations.Fang Wang Kai Fu Yujue Wang Can Pan Xueping Wang Zeyu Liu Chuan Yang Ying Zheng Xiaopeng Li Yu Lu Kenneth Kin Wah To Chenglai Xia Jianye Zhang Zhi Shi Zeping Hu Min Huang Liwu Fu 2024Acta Pharmaceutica Sinica B2024,14,3:0
17A low-cost in-situ CO_(2) sensor based on a membrane and NDIR for long-term measurement in seawater显示文摘The multi-point simultaneous long-term measurement of CO_(2) concentration in seawater can provide more-valuable data for further understanding of the spatial and temporal distribution of CO_(2).Thus,the requirement for a low-cost sensor with high precision,low power consumption,and a small size is becoming urgent.In this work,an in-situ sensor for CO_(2) detection in seawater,based on a permeable membrane and non-dispersive infrared(NDIR)technology,is developed.The sensor has a small size(Ф66 mm×124 mm),light weight(0.7 kg in air),low power consumption(<0.9 W),low cost(Meng LI Baolu DU Jinjia GUO Zhihao ZHANG Zeyu LU Rong’er ZHENG 2022Journal of Oceanology and Limnology2022,40,3:0
18Evolutionary dynamics and conserved function of the Tudor domain-containing(TDRD)proteins in teleost fish显示文摘Tudor domain-containing(TDRD)proteins,the germline enriched protein family,play essential roles in the process of gametogenesis and genome stability through their interaction with the PIWI-interacting RNA(piRNA)pathway.Several studies have suggested the rapid evolution of the piRNA pathway in teleost lineages with striking reproductive diversity.However,there is still limited information about the function and evolution of Tdrd genes in teleost species.In this study,through genome wide screening,13 Tdrd family genes were identified in economically important aquaculture fish,including spotted sea bass(Lateolabrax maculatus),Asian sea bass(Lates calcarifer),and tongue sole(Cynoglossus semilaevis).With copy number,structure,phylogeny,and synteny analysis,duplication of Tdrd6 and Tdrd7,as well as loss of Stk31 and Tdrd10,were characterized in teleost lineages.Codon based molecular evolution analysis indicated faster evolution of teleost Tdrd genes than that in mammals,potentially associated with the accelerated evolution of the piRNA pathway in teleost lineages.The evolutionary diversity of Tdrd genes was also detected between different teleost lineages.RNA-seq analysis showed that most teleost Tdrd genes were dominantly expressed in gonads,particularly highly expressed in testis,such as Tdrd6,Tdrd7a,Tdrd9,Ecat8,and Tdrd15.The varied expression and evolutionary pattern between the duplicated Tdrd6 and Tdrd7 in teleosts may indicate their functional diversification.All these results suggest a conserved function of teleost Tdrd family in gametogenesis and the piRNA pathway,which could lay a foundation for the evolution of Tdrd genes and be helpful for further deciphering of Tdrd functions in teleosts.Zeyu Liu Saisai Liu Shiyang Guo Wei Lu Quanqi Zhang Jie Cheng 2022Marine Life Science & Technology2022,4,1:0
19Pushing the Electrochemical Performance Limits of Polypyrrole Toward Stable Microelectronic Devices显示文摘Conducting polymers have achieved remarkable attentions owing to their exclusive characteristics,for instance,electrical conductivity,high ionic conductivity,visual transparency,and mechanical tractability.Surface and nanostructure engineering of conjugated conducting polymers offers an exceptional pathway to facilitate their implementation in a variety of scientific claims,comprising energy storage and production devices,flexible and wearable optoelectronic devices.A two-step tactic to assemble high-performance polypyrrole(PPy)-based microsupercapacitor(MSC)is utilized by transforming the current collectors to suppress structural pulverization and increase the adhesion of PPy,and then electrochemical co-deposition of PPy-CNT nanostructures on rGO@Au current collectors is performed.The resulting fine patterned MSC conveyed a high areal capacitance of 65.9 mF cm^(−2)(at a current density of 0.1 mA cm^(−2)),an exceptional cycling performance of retaining 79%capacitance after 10,000 charge/discharge cycles at 5 mA cm^(−2).Benefiting from the intermediate graphene,current collector free PPy-CNT@rGO flexible MSC is produced by a facile transfer method on a flexible substrate,which delivered an areal capacitance of 70.25 mF cm^(−2) at 0.1 mA cm^(−2) and retained 46%of the initial capacitance at a current density of 1.0 mA cm^(−2).The flexible MSC is utilized as a skin compatible capacitive micro-strain sensor with excellent electromechanochemical characteristics.Muhammad Tahir Liang He Lihong Li Yawei Cao Xiaoxia Yu Zehua Lu Xiaoqiao Liao Zeyu Ma Yanlin Song 2023Nano-Micro Letters2023,15,4:0
20Fuzzy Adaptive Filtering-Based Energy Management for Hybrid Energy Storage System显示文摘Regarding the problem of the short driving distance of pure electric vehicles,a battery,super-capacitor,and DC/DC converter are combined to form a hybrid energy storage system(HESS).A fuzzy adaptive filtering-based energy management strategy(FAFBEMS)is proposed to allocate the required power of the vehicle.Firstly,the state of charge(SOC)of the super-capacitor is limited according to the driving/braking mode of the vehicle to ensure that it is in a suitable working state,and fuzzy rules are designed to adaptively adjust the filtering time constant,to realize reasonable power allocation.Then,the positive and negative power are determined,and the average power of driving/braking is calculated so as to limit the power amplitude to protect the battery.To verify the proposed FAFBEMS strategy for HESS,simulations are performed under the UDDS(Urban Dynamometer Driving Schedule)driving cycle.The results show that the FAFBEMS strategy can effectively reduce the current amplitude of the battery,and the final SOC of the battery and super-capacitor is optimized to varying degrees.The energy consumption is 7.8%less than that of the rule-based energy management strategy,10.9%less than that of the fuzzy control energy management strategy,and 13.1%less than that of the filtering-based energy management strategy,which verifies the effectiveness of the FAFBEMS strategy.Xizheng Zhang Zhangyu Lu Chongzhuo Tan Zeyu Wang 2021Computer Systems Science & Engineering2021,36,1:0
