| 1 | Multiresidue determination and potential risks of emerging pesticides in aquatic products from Northeast China by LC-MS/MS显示文摘A simple method for determining 33 pesticides with a wide polarity range(log Kow0.6-4.5) in aquatic products was developed based on LC–MS/MS. The target analytes included three types of widely used pesticides: insecticides, fungicides and herbicides. Based on the optimization of ultrasonic assisted extraction and GPC clean-up procedures, the matrix effect, extraction recoveries and LOD were improved distinctively. LOQ of this method was below 0.5 ng/g for all pesticides, which is superior to values in the literature, and the matrix effect was reduced effectively(-14.7% to 7.5%). The method was successfully applied to investigate the pesticide residue levels of twenty-five samples including seven common kinds of fishes from Northeast China. The results showed that all targeted pesticides were present in the fish samples; however, their levels were low, except for atrazine, linuron,ethoprophos, tetrachlorvinphos, acetochlor and fenthion. Atrazine and linuron caught our attention because the concentrations of atrazine in fish samples from Liaoning province were in the range of 0.5-8 ng/g(w/w) with mean concentration of 2.3 ng/g, which were far above those of other pesticides. The levels of linuron were in the range of 0.6-6 ng/g(mean concentration 2.8 ng/g), which were the highest among all targeted pesticides in the Inner Mongolia. This is the first systematic investigation on the characteristics and levels of these pesticides in aquatic products from northeast China. Considering their toxicity and bioaccumulation, the potential risk of atrazine and linuron from consuming aquatic products should be paid more attention. | Lei Fu Xianbo Lu Jun Tan Longxing Wang Jiping Chen | 2018 | Journal of Environmental Sciences2018，30，1： | 17 |
| 2 | Hexabromocyclododecane and tetrabromobisphenol A in sediments and paddy soils from Liaohe River Basin, China: Levels, distribution and mass inventory显示文摘Hexabromocyclododecane(HBCD) and tetrabromobisphenol A(TBBPA) are two kinds of brominated flame retardants and widely present in the environment and biota. The levels,spatial distributions and mass inventories of HBCD and TBBPA were investigated in sediments and paddy soils from the Liaohe River Basin in northeast China. The concentrations of ΣHBCD and TBBPA were in the range of not detected(nd) to 4.02 ng/g dry weight(dw) and 0.03 to 4.06 ng/g dw, respectively. γ-HBCD was dominated in sediments,while the abundance of α-HBCD was relatively high in paddy soils. The spatial distributions of HBCD and TBBPA in surface sediments and paddy soils indicated that the local point-input was their major source. The significant correlation between total organic carbon(TOC) contents and the HBCD levels suggested that TOC content also exerted an influence on the distribution of HBCD in sediments. Meanwhile, it was found that the irrigation with river water was not the major transportation pathway of HBCD and TBBPA in paddy soils. Based on the study, it was estimated that there were about 1.67 tons HBCD and 2.20 tons TBBPA deposited into sediments of the Liaohe River system every year. The total mass inventories of HBCD and TBBPA in sediments were far higher than that in paddy soils. | Fang Li Jing Jin Dongqin Tan Longxing Wang Ningbo Geng Rong Cao Yuan Gao Jiping Chen | 2016 | Journal of Environmental Sciences2016，28，10： | 7 |

| 5 | Asymmetric flow effect in a horizontal natural ventilated tunnel with different aspect ratios under the influence of longitudinal fire locations显示文摘This paper has analyzed the asymmetric flow effect of fire-induced thermal flow in a horizontal tunnel under the natural ventilation condition by conducting large eddy simulations (LES). The key objective is to reveal and to have a better understanding of the asymmetric flow effect caused by the upstream and downstream tunnel length difference. The mechanism behind it can be explained based on the conservation of mass and dynamic force analysis on the smoke and fresh air. The strength of the asymmetric flow effect is characterized by the mass flow rate of the induced longitudinal flow (net mass flow rate of a cross-section). An empirical correlation to predict the induced longitudinal mass flow rate is proposed. Furthermore, the law of smoke and air flow distribution within a horizontal tunnel is established. The proportion of smoke (or air) flowing out (or coming in) through the opening increase (or decrease) linearly with the increasing distance between that opening to the fire location. The variation of the air flow with the longitudinal fire location in a tunnel is more sensitive than the smoke flow. Results have shown that as the fire approaches the tunnel exit from the middle of the tunnel, the smoke spilling out through this opening is reduced from 50% to 40%, while the fresh air incoming from this opening is increased from 50% to 100% and vice versa. | Longxing Yu Huaxian Wan Jie Ji | 2021 | Building Simulation2021，14，4： | 3 |
| 6 | Switch type PANI/ZnO core-shell microwire heterojunction for UV photodetection显示文摘In this study,single crystal ZnO microwires(MW)with size of~5.4 mm×30μm are prepared through a chemical vapor deposition technique at high temperature(1200℃).Subsequently,p-type conducting polyaniline(PANI)polymers with different conductivities are densely coated on part of the ZnO MW to construct organic/inorganic core-shell heterojunction photodetectors.The hetero-diodes reach an extremely high rectifcation ratio(I_(+3V)/I_(-3V))of 749230,and a maximum rejection ratio(I_(350nm)/I_(dark))of 3556(at-3 V),indicating great potential as rectifed switches.All the heterojunction devices exhibit strong response to ultraviolet(UV)radiation with high response speed.Moreover,the obvious photovoltaic behavior can also be obtained,allowing the device to operate as an independent and stable unit without externally supplied power.Under 0 V bias voltage,the self-powered photodetector shows a maximum responsivity of 0.56 mA W~(-1)and a rapid response speed of 0.11 ms/1.45 ms(rise time/decay time).Finally,a fnite difference time domain(FDTD)simulation is performed to further demonstrate the interaction mechanism between the incident light feld and the hexagonal cavity,which strongly supports the enhancement of the light absorption in whispering-gallery-mode resonator. | Yihan Chen Longxing Su Mingming Jiang Xiaosheng Fang | 2022 | Journal of Materials Science & Technology2022，，10： | 3 |

| 8 | Physics-informed neural network approach for heat generation rate estimation of lithium-ion battery under various driving conditions显示文摘Accurate insight into the heat generation rate(HGR) of lithium-ion batteries(LIBs) is one of key issues for battery management systems to formulate thermal safety warning strategies in advance.For this reason,this paper proposes a novel physics-informed neural network(PINN) approach for HGR estimation of LIBs under various driving conditions.Specifically,a single particle model with thermodynamics(SPMT) is first constructed for extracting the critical physical knowledge related with battery HGR.Subsequently,the surface concentrations of positive and negative electrodes in battery SPMT model are integrated into the bidirectional long short-term memory(BiLSTM) networks as physical information.And combined with other feature variables,a novel PINN approach to achieve HGR estimation of LIBs with higher accuracy is constituted.Additionally,some critical hyperparameters of BiLSTM used in PINN approach are determined through Bayesian optimization algorithm(BOA) and the results of BOA-based BiLSTM are compared with other traditional BiLSTM/LSTM networks.Eventually,combined with the HGR data generated from the validated virtual battery,it is proved that the proposed approach can well predict the battery HGR under the dynamic stress test(DST) and worldwide light vehicles test procedure(WLTP),the mean absolute error under DST is 0.542 kW/m^(3),and the root mean square error under WLTP is1.428 kW/m^(3)at 25℃.Lastly,the investigation results of this paper also show a new perspective in the application of the PINN approach in battery HGR estimation. | Hui Pang Longxing Wu Jiahao Liu Xiaofei Liu Kai Liu | 2023 | Journal of Energy Chemistry2023，，3： | 2 |
| 9 | Monitoring gas-and particulate-phase short-chain polychlorinated paraffins in the urban air of Dalian by a self-developed passive sampler显示文摘The concentration of short-chain polychlorinated paraffins(SCCPs) in the urban air of Dalian,China was monitored from September 2016 to August 2017 with a self-developed passive sampler(PAS1) and an active high-volume sampler, simultaneously. PAS1 successfully collected the entire target SCCPs in the ambient air. Air SCCPs sampled by PAS1 were found be in the linear uptake stage during 181 days of sampling. Passive and active samples showed comparable congener profiles, and the dominant contributors of SCCPs in the two kinds of samples were similar. A significant linear correlation was observed between the total concentration of SCCPs sampled by PAS1 and active sampler in the four seasons. The passive sampling rates of the PAS1 for the gas and particulate phases of SCCPs were measured. The quantitative structure–property relationship of the sampling rate of PAS1(Rair) for gas-phase SCCPs was studied. From the molecular point of view, Rairwas mainly affected by the molecular weight and sub-cooled liquid vapor pressure of SCCPs. In general, SCCPs in the urban air of Dalian mainly existed in gas phase,lower molecular weight SCCPs primarily occurred in the gas phase, whereas higher molecular weight SCCPs were predominately adsorbed or absorbed on airborne particles. The air concentration of SCCPs in the four seasons were different, the correlation of the concentration of SCCPs in the air with the meteorology parameters was conducted. The exposure risk by intake air SCCPs of the residents around the sampling sites was evaluated according to the European risk assessment standards. | Yifan Wang Xiuhua Zhu Yuan Gao Hao Bai Pengyuan Wang Jiping Chen Heping Yuan Longxing Wang Xiaoxiao Li Wei Wang | 2019 | Journal of Environmental Sciences2019，31，6： | 2 |
| 10 | Scalable manufacture of vertical p-GaN/n-SnO_(2) heterostructure for self-powered ultraviolet photodetector, solar cell and dual-color light emitting diode显示文摘Vertical SnO_(2)based p-n junctions are pivotal since they built the core components in photoelectronic systems.Nevertheless,preparation of high-quality p-SnO_(2)with controllable hole mobility and concentration is still a great challenge owing to the self-compensating effect and lattice distortion caused by the radius discrepancy between host and doped atoms.Herein,p type GaN:Mg grown by metal organic chemical vapor deposition is employed as hole transportation layer to construct p-n heterojunction with intrinsic n-SnO_(2)prepared by atomic layer deposition.Both material preparation techniques are compatible with current industrial mass production processes.The p-GaN/n-SnO_(2)heterojunction can be developed as solar cell,dual-color light emitting diode and self-powered,high speed ultraviolet(UV)photodetector with external quantum efficiency of 74%at 0 V bias voltage.In addition,direct recombination of donor bound excitons(D0 X)and UV emission red shifts caused by quantum confinement Stack effect are observed in SnO_(2).Since our device fabrication technique is a standard craft in photoelectronics,the study of p-GaN/n-SnO_(2)heterojunction suggests a simple and effective strategy for large scale device integration in next generation high performance photoelectronic devices. | Longxing Su Yuqing Zuo Jin Xie | 2021 | InfoMat2021，3，5： | 2 |
