| 1 | Assessment of heavy metal pollution characteristics and human health risk of exposure to ambient PM_(2.5) in Tianjin,China显示文摘To examine the features of heavy metal pollution of PM_(2.5)(particulate matter less than 2.5 μm) in Tianjin,China,as well as the exposure risk of PM_(2.5) to human health,we analyzed ambient PM_(2.5) samples collected from a campus of Nankai University in June,August,and October 2012.The concentrations of PM_(2.5) and heavy metals(Ni,Cu,Pb,Zn,Cr,Cd,Hg,As and Mn) in PM2.5 were analyzed by gravimetric analysis and inductively coupled plasma-mass spectrometry,respectively.The results show that the heavy metals contained in PM_(2.5) were,in descending order,Cu,Zn,Pb,Mn,Cr,Ni,Cd,As,and Hg.The proportion of Cd exceeded the secondary level of National Ambient Air Quality Standard of China(GB 3095-2012) by 1.3times,while others were within the limit.Enrichment factor analysis indicated that Cu,Zn,Cd,Pb,and Hg are mainly from anthropogenic sources.Principal component analysis indicated that the main sources of the heavy metals are vehicle exhaust,chemical waste,and coal-burning activities.The nine heavy metals which may cause health issues by exposure through the human respiratory system and should be further examined are Cr,Cd,As,Ni,Cu,Pb,Mn,Zn,and Hg,in the order of decreasing risk levels.With reference to the U.S.EPA standard the risk levels of all nine metals were below the acceptable level(10^(-6)/year). | Peifei Chen Xiaohui Bi Jiaqi Zhang Jianhui Wu Yinchang Feng | 2015 | Particuology2015，13，3： | 43 |
| 2 | Perturbed Solving Method for Interdecadal Sea-air Oscillator Model显示文摘A coupled system of the interdecadal sea-air oscillator model is studied.The El Nio-southern oscillation(ENSO) atmospheric physics oscillation is an abnormal phenomenon involved in the tropical Pacific ocean-atmosphere interactions.The oscillator model is involved with the variations of both the eastern and western Pacific anomaly pat-terns.This paper proposes an ENSO atmospheric physics model using a method of the perturbation theory.The aim is to create an asymptotic solving method for the ENSO model.Employing the perturbed method,the asymptotic solution of corresponding problem is obtained,and the asymptotic behaviour of the solution is studied.Thus we can obtain the prognoses of the sea surface temperature anomaly and related physical quantities. | MO Jiaqi LIN Yihua LIN Wantao CHEN Lihua | 2012 | Chinese Geographical Science2012，22，1： | 38 |

| 4 | Environmentally Friendly and Multifunctional Shaddock Peel-Based Carbon Aerogel for Thermal-Insulation and Microwave Absorption显示文摘Eco-friendly electromagnetic wave absorbing materials with excellent thermal infrared stealth property,heat-insulating ability and compression resistance are highly attractive in practical applications.Meeting the aforesaid requirements simultaneously is a formidable challenge.Herein,ultra-light carbon aerogels were fabricated via fresh shaddock peel by facile freeze-drying method and calcination process,forming porous network architecture.With the heating platform temperature of 70℃,the upper surface temperatures of the as-prepared carbon aerogel present a slow upward trend.The color of the sample surface in thermal infrared images is similar to that of the surroundings.With the maximum compressive stress of 2.435 kPa,the carbon aerogels can provide favorable endurance.The shaddock peel-based carbon aerogels possess the minimum reflection loss value(RLmin)of−29.50 dB in X band.Meanwhile,the effective absorption bandwidth covers 5.80 GHz at a relatively thin thickness of only 1.7 mm.With the detection theta of 0°,the maximum radar cross-sectional(RCS)reduction values of 16.28 dB m^(2) can be achieved.Theoretical simulations of RCS have aroused extensive interest owing to their ingenious design and time-saving feature.This work paves the way for preparing multi-functional microwave absorbers derived from biomass raw materials under the guidance of RCS simulations. | Weihua Gu Jiaqi Sheng Qianqian Huang Gehuan Wang Jiabin Chen Guangbin Ji | 2021 | Nano-Micro Letters2021，13，7： | 11 |
| 5 | Factors influencing the concentration of negative air ions during the year in forests and urban green spaces of the Dapeng Peninsula in Shenzhen, China显示文摘Negative air ions(NAIs)benefit the mental and physical health of humans,but rapid urbanization can decrease the abundance of NAIs.Quantifying the spatial and seasonal distribution of NAIs and determining the factors that infl uence the concentration during urbanization is thus essential.In the present study of a typical developing urban district in southern China,negative air ion concentrations(NAICs)in 60 forests sites and 30 urban green spaces were quantifi ed on seven consecutive days in each of the four seasons.Large seasonal variations in NAIC were revealed in forests and urban green spaces with trough values in summer.NAIC progressively decreased from forests to urban green spaces and was infl uenced by local land morphology,vegetation characteristics,and climatic factors.The vast,heavily vegetated northeastern region was the richest area for NAIs,whereas the narrow central region(urbanized area)was the poorest,implying dramatic impacts of urbanization on the spatial distribution of NAIs.The relationship between air temperature and NAIC was better fi tted with a quadratic equation than a linear equation.Moreover,the NAIC was more sensitive to local morphology in urban green spaces than in urban forests,indicating the vulnerability of NAIs in urbanized areas.Therefore,the appropriate design of local urban morphology is critical. | Yafei Wang Zhuobiao Ni Di Wu Chen Fan Jiaqi Lu Beicheng Xia | 2020 | Journal of Forestry Research2020，31，6： | 11 |
| 6 | Survey of locomotion control of legged robots inspired by biological concept显示文摘Compared with wheeled mobile robots, legged robots can easily step over obstacles and walk through rugged ground. They have more flexible bodies and therefore, can deal with complex environment. Nevertheless, some other issues make the locomotion control of legged robots a much complicated task, such as the redundant degree of freedoms and balance keeping. From literatures, locomotion control has been solved mainly based on programming mechanism. To use this method, walking trajectories for each leg and the gaits have to be designed, and the adaptability to an unknown environment cannot be guaranteed. From another aspect, studying and simulating animals' walking mechanism for engineering application is an efficient way to break the bottleneck of locomotion control for legged robots. This has attracted more and more attentions. Inspired by central pattern generator (CPG), a control method has been proved to be a successful attempt within this scope. In this paper, we will review the biological mechanism, the existence evidences, and the network properties of CPG. From the en- gineering perspective, we will introduce the engineering simulation of CPG, the property analysis, and the research progress of CPG inspired control method in locomotion control of legged robots. Then, in our research, we will further discuss on existing problems, hot issues, and future research directions in this field. | WUQiDi LIU ChengJu ZHANG JiaQi CHEN QiJun | 2009 | Science in China(Series F)2009，52，10： | 11 |

| 9 | Mesoporous Graphene Hosts for Dendrite-Free Lithium Metal Anode in Working Rechargeable Batteries显示文摘Lithium(Li) metal anode has received extensive attentions due to its ultrahigh theoretical capacity and the most negative electrode potential. However, dendrite growth severely impedes the practical applications of the Li metal anode in rechargeable batteries. In this contribution, a mesoporous graphene with a high specific surface area was synthesized to host the Li metal anode. The mesoporous graphene host(MGH) has a high specific surface area(2090 m^2/g), which affords free space and an interconnected conductive pathway for Li plating and stripping, thus alleviating the volume variation and reducing the generation of dead Li during repeated cycles. More importantly, the high specific surface area of MGH efficiently reduces the local current density of the electrode, which favors a uniform Li nucleation and plating behavior, rendering a dendritefree deposition morphology at a low overpotential. These factors synergistically boost the Li utilization(90.1% vs. 70.1% for Cu foil) and life span(150 cycles vs. 100 cycles for Cu foil) with a low polarization of MGH electrode at an ultrahigh current of 15.0 mA/cm^2. The as-prepared MGH can provide fresh insights into the electrode design of the Li metal anode operating at high rates. | He Liu Xinbing Cheng Rui Zhang Peng Shi Xin Shen Xiaoru Chen Tao Li Jiaqi Huang Qiang Zhang | 2020 | Transactions of Tianjin University2020，26，2： | 9 |
| 10 | Detection and suppression of narrow band RFI for synthetic aperture radar imaging显示文摘Radio frequency interference(RFI) is becoming more and more frequently, which makes it an important issue in SAR imaging.RFI presented in synthetic aperture radar either on purpose or inadvertent will distort the useful SAR echoes, thus degrade the SAR image quality.To resolve this issue, a long time study was carried out to study the characteristic of the RFI through the RFIaffected spaceborne and airborne SAR data.Based on the narrow band nature of RFI, this paper proposes a new process which contains both RFI detection and RFI suppression.A useful subband spectral kurtosis detector is first used to detect RFI, and then its results are used for RFI suppression.The proposed process has two advantages: one is the economization on the compute time for unnecessary interference suppression when no RFI existed; the other is improving the performance of the suppression method with knowing the exact position where RFI is.Moreover, the previous RFI suppression method––subband spectral cancelation(SSC) is supplemented and perfected.The subband division step is also elaborated detail in this paper.The experiment results show that the subband spectral kurtosis detector exhibits good performance in recognizing both weak and narrow-band RFI.In addition, the validity of the SSC method with subband spectral kurtosis detector is also validated on the real SAR echoes. | Yang Lin Zheng Huifang Feng Jin Li Ning Chen Jiaqi | 2015 | Chinese Journal of Aeronautics2015，28，4： | 8 |

| 13 | New innovations in pavement materials and engineering:A review on pavement engineering research 2021显示文摘Sustainable and resilient pavement infrastructure is critical for current economic and environmental challenges.In the past 10 years,the pavement infrastructure strongly supports the rapid development of the global social economy.New theories,new methods,new technologies and new materials related to pavement engineering are emerging.Deterioration of pavement infrastructure is a typical multi-physics problem.Because of actual coupled behaviors of traffic and environmental conditions,predictions of pavement service life become more and more complicated and require a deep knowledge of pavement material analysis.In order to summarize the current and determine the future research of pavement engineering,Journal of Traffic and Transportation Engineering(English Edition)has launched a review paper on the topic of'New innovations in pavement materials and engineering:A review on pavement engineering research 2021'.Based on the joint-effort of 43 scholars from 24 well-known universities in highway engineering,this review paper systematically analyzes the research status and future development direction of 5 major fields of pavement engineering in the world.The content includes asphalt binder performance and modeling,mixture performance and modeling of pavement materials,multi-scale mechanics,green and sustainable pavement,and intelligent pavement.Overall,this review paper is able to provide references and insights for researchers and engineers in the field of pavement engineering. | JTTE Editorial Office Jiaqi Chen Hancheng Dan Yongjie Ding Yangming Gao Meng Guo Shuaicheng Guo Bingye Han Bin Hong Yue Hou Chichun Hu Jing Hu Ju Huyan Jiwang Jiang Wei Jiang Cheng Li Pengfei Liu Yu Liu Zhuangzhuang Liu Guoyang Lu Jian Ouyang Xin Qu Dongya Ren Chao Wang Chaohui Wang Dawei Wang Di Wang Hainian Wang Haopeng Wang Yue Xiao Chao Xing Huining Xu Yu Yan Xu Yang Lingyun You Zhanping You Bin Yu Huayang Yu Huanan Yu Henglong Zhang Jizhe Zhang Changhong Zhou Changjun Zhou Xingyi Zhu | 2021 | Journal of Traffic and Transportation Engineering(English Edition)2021，8，6： | 7 |
| 14 | Effects of cerium incorporation on the catalytic oxidation of benzene over flame-made perovskite La_(1-x)Ce_xMnO_3 catalysts显示文摘Perovskite-type La_(1-x)Ce_xMnO_3(x = 0-10%) catalysts were prepared by flame spray pyrolysis and their activities during the catalytic oxidation of benzene were examined over the temperature range of100-450℃.The structural properties and reducibility of these materials were also characterized by X-ray diffraction(XRD),N_2 adsorption/desorption,H_2 temperature-programmed reduction(H_2-TPR) and X-ray photoelectron spectroscopy(XPS).The incorporation of Ce was found to improve the benzene oxidation activity,and the perovskite in which x was 0.1 exhibited the highest activity.Phase composition and surface elemental analyses indicated that non-stoichiometric compounds were present.The incorporation of Ce had a negligible effect on the specific surface area of the perovskites and hence this factor has little impact on the catalytic activity.Introduction of Ce4^(4+) resulted in modification of the chemical states of both B-site ions and oxygen species and facilitated the reducibility of the perovskite.The surface Mn^(4+)/Mn^(3+)ratio was increased as a result of Ce^(4+) substitution,while a decrease in the surface-adsorbed O/lattice O(O_(ads)/O_(latt)) ratio was observed.The relationship between the surface elemental ratios and catalytic activity was established to allow a better understanding of the process by which benzene is oxidized over perovskites. | Gang Liu Jiaqi Li Kun Yang Wenxiang Tang Haidi Liu Jun Yang Renliang Yue Yunfa Chen | 2015 | Particuology2015，13，2： | 6 |

| 16 | Imputation from SNP chip to sequence: a case study in a Chinese indigenous chicken population显示文摘Background: Genome-wide association studies and genomic predictions are thought to be optimized by using whole-genome sequence(WGS) data. However, sequencing thousands of individuals of interest is expensive.Imputation from SNP panels to WGS data is an attractive and less expensive approach to obtain WGS data. The aims of this study were to investigate the accuracy of imputation and to provide insight into the design and execution of genotype imputation.Results: We genotyped 450 chickens with a 600 K SNP array, and sequenced 24 key individuals by whole genome re-sequencing. Accuracy of imputation from putative 60 K and 600 K array data to WGS data was 0.620 and 0.812 for Beagle, and 0.810 and 0.914 for FImpute, respectively. By increasing the sequencing cost from 24 X to 144 X, the imputation accuracy increased from 0.525 to 0.698 for Beagle and from 0.654 to 0.823 for FImpute. With fixed sequence depth(12 X), increasing the number of sequenced animals from 1 to 24, improved accuracy from 0.421 to0.897 for FImpute and from 0.396 to 0.777 for Beagle. Using optimally selected key individuals resulted in a higher imputation accuracy compared with using randomly selected individuals as a reference population for resequencing. With fixed reference population size(24), imputation accuracy increased from 0.654 to 0.875 for FImpute and from 0.512 to 0.762 for Beagle as the sequencing depth increased from 1 X to 12 X. With a given total cost of genotyping, accuracy increased with the size of the reference population for FImpute, but the pattern was not valid for Beagle, which showed the highest accuracy at six fold coverage for the scenarios used in this study.Conclusions: In conclusion, we comprehensively investigated the impacts of several key factors on genotype imputation. Generally, increasing sequencing cost gave a higher imputation accuracy. But with a fixed sequencing cost, the optimal imputation enhance the performance of WGP and GWAS. An optimal imputation strategy should take size of reference population, imputation algorithms, marker density, and population structure of the target population and methods to select key individuals into consideration comprehensively. This work sheds additional light on how to design and execute genotype imputation for livestock populations. | Shaopan Ye Xiaolong Yuan Xiran Lin Ning Gao Yuanyu Luo Zanmou Chen Jiaqi Li Xiquan Zhang Zhe Zhang | 2018 | Journal of Animal Science and Biotechnology2018，9，2： | 6 |
| 17 | Recent advances in photodynamic therapy based on emerging two-dimensional layered nanomaterials显示文摘Photodynamic therapy(PDT)is a promising non-invasive therapy approach for various diseases including malignant tumor.The process of PDT involves three interrelated aspects,namely photosensitizer(PS),light source,and oxygen,among which PS is the decisive factor that determines its anticancer efficiency.There exist some defects in currently applied PDT,such as inadequate production of reactive oxygen species(ROS),poor penetration of exciting light,insufficient oxygen supply,and nonselective distribution of PS.With unique physicochemical and optical properties,two-dimensional nanomaterials(2DNMs)have aroused great interest in biomedical fields.2DNMs-based PDT is promising to significantly improve antitumor efficacy compared to conventional PDT.In this review,we will firstly introduce the underlying mechanism of PDT and how 2DNMs are absorbed and distribute inside tumor cells.After that,we will not only illustrate how 2DNMs-based PDT can enhance tumor-killing efficacy and minimize side-effects through conquering the above-mentioned defects of conventional PDT and the preparation process of 2DNMs,but also elaborate recent advances about 2DNMs-based PDT.Lastly,we will summarize the challenges and future prospects of 2DNMs-based PDT. | Xinqiang Wu Xiaofeng Jiang Taojian Fan Zhiwei Zheng Zhaoyuan Liu Yubin Chen Liangqi Cao Zhongjian Xie Dawei Zhang Jiaqi Zhao Qiwen Wang Zhenhui Huang Zhijian Chen Ping Xue Han Zhang | 2020 | Nano Research2020，13，6： | 6 |

| 20 | Polyoxometalate-based silica-supported ionic liquids for heterogeneous oxidative desulfurization in fuels显示文摘With the aim of deep desulfurization, silica-supported polyoxometalate-based ionic liquids were successfully prepared by a one-pot hydrothermal process and employed in heterogeneous oxidative desulfurization of various sulfur compounds. The compositions and structures of the hybrid samples were characterized by various methods such as FT-IR, XPS, Raman,UV–Vis, wide-angle XRD and N_2 adsorption–desorption. The experimental results indicated that the hybrid materials presented a high dispersion of tungsten species and excellent catalytic activity for the removal of 4,6-dimethyldibenzothiophene without any organic solvent as extractant, and the sulfur removal could reach 100.0% under mild conditions.The catalytic performance on various substrates was also investigated in detail. After cycling seven cycles, the sulfur removal of the heterogeneous system still reached 93.0%. The GC-MS analysis results demonstrated that the sulfur compound was first adsorbed by the catalyst and subsequently oxidized to its corresponding sulfone. | Ming Zhang Miao Wang Jiapeng Yang Hongping Li Jiaqi Liu Xiao Chen Wenshuai Zhu Huaming Li | 2018 | Petroleum Science2018，15，4： | 5 |
