| 2 | Coinfection with influenza A virus enhances SARS-CoV-2 infectivity显示文摘The upcoming flu season in the Northern Hemisphere merging with the current COVID-19 pandemic raises a potentially severe threat to public health.Through experimental coinfection with influenza A virus(IAV)and either pseudotyped or live SARS-CoV-2 virus,we found that IAV preinfection significantly promoted the infectivity of SARS-CoV-2 in a broad range of cell types.Remarkably,in vivo,increased SARS-CoV-2 viral load and more severe lung damage were observed in mice coinfected with IAV.Moreover,such enhancement of SARS-CoV-2 infectivity was not observed with several other respiratory viruses,likely due to a unique feature of IAV to elevate ACE2 expression.This study illustrates that IAV has a unique ability to aggravate SARS-CoV-2 infection,and thus,prevention of IAV infection is of great significance during the COVID-19 pandemic. | Lei Bai Yongliang Zhao Jiazhen Dong Simeng Liang Ming Guo Xinjin Liu Xin Wang Zhixiang Huang Xiaoyi Sun Zhen Zhang Lianghui Dong Qianyun Liu Yucheng Zheng Danping Niu Min Xiang Kun Song Jiajie Ye Wenchao Zheng Zhidong Tang Mingliang Tang Yu Zhou Chao Shen Li Zhou Yu Chen Huan Yan Ke Lan Ke Xu | 2021 | Cell Research2021，31，4： | 16 |
| 3 | Earth surface processes and their effects on human behavior in monsoonal China during the Pleistocene-Holocene epochs显示文摘There is a wide diversity of landforms in China.The topography of three major terraces,decreasing in height stepwise from west to east,was formed by the early Miocene.With the commencement of the Great Northern Hemisphere Glaciations(GHGs)and the glacial-interglacial cycles in the Pleistocene,thick loess deposits accumulated in north China,and fluvial terraces were formed and lakes expanded and contracted in eastern and central China.The earliest evidence of hominins in China is dated to ~1.7 Ma;they occupied the monsoon-dominated region for a long interval,until the late Pleistocene,~50 ka.In this study,we investigated a large area rich in the relics and artifacts of early man.The results indicate that the early humans occupied riverine areas,especially medium-sized fluvial basins,and lake shores.Even in the relatively recent geological past,the occupation and abandonment of settlements were directly forced by the shifting of sand dune fields in the desert-loess transitional zone,which in turn was closely associated with variations in the monsoon climate and vegetation patterns.Our observations indicate that landforms were one of the main determinants of early human behavior,in that loess tableland,large alluvial plains,desert-Gobi areas,and the Tibetan Plateau,were not suitable environments for early human settlement.We infer that the early humans in China adapted their behavior to specific landforms and landform processes.The monsoon climate,which shapes the large-scale step-like pattern of fluvial landforms,promotes vegetation coverage and dominates soil formation,provides a crucial context for early human adaptation.The adaptation of early humans to earth surface processes in East Asia is investigated for the first time in this study.Future investigations will provide further information that will increase our understanding of the linkage between early human behavior and landform processes in East Asia. | LU Huayu ZHUO Haixin ZHANG Wenchao WANG Shejiang ZHANG Hongyan SUN Xuefeng JIA Xin XU Zhiwei WANG Xianyan | 2017 | Journal of Geographical Sciences2017，27，11： | 12 |
| 4 | Realizing over 10% efficiency in polymer solar cell by device optimization显示文摘The low band gap polymer based on benzodithiophene(BDT)-thieno[3,4-b]thiophene(TT)backbone,PBDT-TS1,was synthesized following our previous work and the bulk heterojunction(BHJ)material comprising PBDT-TS1/PC71BM was optimized and characterized.By processing the active layer with different additives i.e.1,8-diiodooctane(DIO),1-chloronaphthalene(CN)and 1,8-octanedithiol(ODT)and optimizing the ratio of each additive in the host solvent,a high PCE of 9.98%was obtained under the condition of utilizing 3%DIO as processing additive in CB.The effect of varied additives on photovoltaic performance was illustrated with atomic force microscopy(AFM)and transmission electron microscope(TEM)measurements that explained changes in photovoltaic parameters.These results provide valuable information of solvent additive choice in device optimization of PBDTTT polymers,and the systematic device optimization could be applied in other efficient photovoltaic polymers.Apparently,this work presents a great advance in single junction PSCs,especially in PSCs with conventional architecture. | Shaoqing Zhang Long Ye Wenchao Zhao Bei Yang Qi Wang Jianhui Hou | 2015 | Science China Chemistry2015，58，2： | 12 |
| 5 | A direct position determination method with combined TDOA and FDOA based on particle filter显示文摘The localization of a stationary transmitter using moving receivers is considered.The original Direct Position Determination(DPD) methods, with combined Time Difference of Arrival(TDOA) and Frequency Difference of Arrival(FDOA), do not perform well under low Signal-toNoise Ratio(SNR), and worse still, the computation cost is difficult to accept when the computational capabilities are limited.To get better positioning performance, we present a new DPD algorithm that proves to be more computationally efficient and more precise for weak signals than the conventional approach.The algorithm partitions the signal received with the same receiver into multiple non-overlapping short-time signal segments, and then uses the TDOA, the FDOA and the coherency among the short-time signals to locate the target.The fast maximum likelihood estimation, one iterative method based on particle filter, is designed to solve the problem of high computation load.A secondary but important result is a derivation of closed-form expressions of the Cramer-Rao Lower Bound(CRLB).The simulation results show that the algorithm proposed in this paper outperforms the traditional DPD algorithms with more accurate results and higher computational efficiency, and especially at low SNR, it is more close to the CRLB. | Zhiyu LU Bin BA Jianhui WANG Wenchao LI Daming WANG | 2018 | Chinese Journal of Aeronautics2018，31，1： | 11 |
| 6 | Efficient microwave-assisted photocatalytic degradation of endocrine disruptor dimethyl phthalate over composite catalyst ZrO_x /ZnO显示文摘A highly active ZrO x /ZnO catalyst for microwave-assisted photocatalytic (MW/PC) degradation of endocrine disruptor dimethyl phthalate (DMP) has been prepared via cetyltrimethylammonium assisted hydrothermal method. The ZrO x /ZnO was characterized by XPS, XRD, UV-Vis, BET and SEM techniques. The XPS result showed that Zr oxides with different valences (+2, +3, +4) co-existed in ZrO x /ZnO. By using the ZrO x /ZnO (0.1 g), the TOC removal efficiency of DMP (100 mL of 50 mg/L) was 88% after 30 min reaction, which was about 15% higher than P25 TiO 2 . It was found that the removal process of DMP by MW/PC followed pseudo first-order kinetics in all cases, and ZrO x /ZnO significantly accelerated the degradation of DMP. The degradation half-life time of DMP was shortened 45% compared with P25 TiO 2 . A possible catalytic mechanism was proposed based on microwave response and interfacial charge transfer. ZrO x /ZnO could be reused for six times without obvious decrease in catalytic activity. The study offers new insights into designing highly efficient catalysts for MW/PC process and is applicable for MW/PC environmental remediation. | Wenchao Liao, Tong Zheng, Peng Wang, Sisi Tu, Weiqian PanState Key Laboratory of Urban Water Resource and Environment, School of Municipal and Environmental Engineering, Harbin Institute of Technology, Harbin 150090, China. | 2010 | Journal of Environmental Sciences2010，22，11： | 9 |
| 7 | Pulsating hydraulic fracturing technology in low permeability coal seams显示文摘Based on the difficult situation of gas drainage in a single coal bed of high gas content and low permeability, we investigate the technology of pulsating hydraulic pressure relief, the process of crank plunger movement and the mechanism of pulsating pressure formation using theoretical research, mathematical modeling and field testing. We analyze the effect of pulsating pressure on the formation and growth of fractures in coal by using the pulsating hydraulic theory in hydraulics. The research results show that the amplitude of fluctuating pressure tends to increase in the case where the exit is blocked, caused by pulsating pressure reflection and frictional resistance superposition, and it contributes to the growth of fractures in coal. The crack initiation pressure of pulsating hydraulic fracturing is 8 MPa, which is half than that of normal hydraulic fracturing; the pulsating hydraulic fracturing influence radius reaches 8 m.The total amount of gas extraction is increased by 3.6 times, and reaches 50 L/min at the highest point.The extraction flow increases greatly, and is 4 times larger than that of drilling without fracturing and 1.2times larger than that of normal hydraulic fracturing. The technology provides a technical measure for gas drainage of high gas content and low permeability in the single coal bed. | Wang Wenchao Li Xianzhong Lin Baiquan Zhai Cheng | 2015 | International Journal of Mining Science and Technology2015，25，4： | 9 |
| 8 | Radar Target Recognition Algorithm Based on RCS Observation Sequence——Set-Valued Identification Method显示文摘This paper studies the problem of radar target recognition based on radar cross section(RCS)observation sequence.First,the authors compute the discrete wavelet transform of RCS observation sequence and extract a valid statistical feature vector containing five components.These five components represent five different features of the radar target.Second,the authors establish a set-valued model to represent the relation between the feature vector and the authenticity of the radar target.By set-valued identification method,the authors can estimate the system parameter,based on which the recognition criteria is given.In order to illustrate the efficiency of the proposed recognition method,extensive simulations are given finally assuming that the true target is a cone frustum and the RCS of the false target is normally distributed.The results show that the set-valued identification method has a higher recognition rate than the traditional fuzzy classification method and evidential reasoning method. | WANG Ting BI Wenjian ZHAO Yanlong XUE Wenchao | 2016 | Journal of Systems Science & Complexity2016，29，3： | 7 |
| 9 | Radial acceleration estimation within one pulse echo based on Hough-ambiguity transformation显示文摘The information of acceleration of a highly maneuverable target can be helpful to enhancing the performance of the tracker and facilitating the classification of targets.However,the current radars cannot provide information on the acceleration of the target in signal processing.Conventionally,acceleration is estimated by using Kalman filtering in several pulse echoes.There are limitations and shortcomings in this method because of its low precision.This paper proposes a Hough-ambiguity transformation(HAT) method for estimating the acceleration within one pulse.Simulations results validate the effectiveness of the proposed algorithm under several conditions with different pulse durations,signal to noise ratios(SNR),searching steps and searching radii respectively.Simulation results also show that the performance of the proposed method is superior to that of other methods. | WANG GuoHong JIA ShuYi DU WenChao | 2010 | Science China(Information Sciences)2010，53，9： | 7 |
| 10 | Personalized Privacy-Preserving Trajectory Data Publishing显示文摘Due to the popularity of mobile internet and location-aware devices,there is an explosion of location and tra jectory data of moving objects.A few proposals have been proposed for privacy preserving tra jectory data publishing,and most of them assume the attacks with the same adversarial background knowledge.In practice,different users have different privacy requirements.Such non-personalized privacy assumption does not meet the personalized privacy requirements,meanwhile,it looses the chance to achieve better utility by taking advantage of differences of users' privacy requirements.We study the personalized tra jectory k-anonymity criterion for trajectory data publication.Specifically,we explore and propose an overall framework which provides privacy preserving services based on users' personal privacy requests,including tra jectory clustering,editing and publication.We demonstrate the efficiency and effectiveness of our scheme through experiments on real world dataset. | LU Qiwei WANG Caimei XIONG Yan XIA Huihua HUANG Wenchao GONG Xudong | 2017 | Chinese Journal of Electronics2017，26，2： | 6 |
| 11 | Thermodynamic study and syntheses of β-SiAlON ceramics显示文摘Based on the thermodynamic study of β-SiAlON and one section of Si-Al-O-N phase diagram for Si/Al=9 at 1773 K, the pure β-SiAlON (Si6-ZAlZOZN8-Z) ceramics with different Z values (viz. 1.4, 1.8, 2.2, 2.6, 3.0) were synthesized at different temperatures using the pressure-less technique. The relationship of the experimental-saturated Z value (the maximum Z value at a constant temperature) with temperature was then discussed. The experimental results indicated that there is a good linear relationship between Z value and temperature, which is Z=_10.76+0.0071T (R=0.9985). The β-SiAlON stability regions at different temperatures were exhibited in a sketch phase diagram of Si3N4-SiO2-Al2O3-AlN system. In addi- tion, the relationship between experimental-saturated Z value and the lattice parameters was also characterized, and the linear regression results a=7.604+0.02872Z and c=2.908+0.02496Z were obtained, respectively. | DONG PengLi WANG XiDong ZHANG Mei GUO Min LI WenChao | 2009 | Science China(Technological Sciences)2009，52，11： | 5 |
| 12 | Transition metal carbides in electrocatalytic oxygen evolution reaction显示文摘Oxygen evolution reaction(OER) is admitted to an important half reaction in water splitting for sustainable hydrogen production.The sluggish four-electron process is known to be the bottleneck for enhancing the efficiency of OER.In this regard,tremendous efforts have been devoted to developing effective catalysts for OER.In addition to Ir-or Ru-based oxides taken as the benchmark,transition metal carbides have attracted ever-increasing interest due to the high activity and stability as low-cost OER electrocatalysts.In this review,the transition metal carbides for water oxidation electrocatalysis concerning design strategies and synthesis are briefly summarized.Some typical applications for various carbides are also highlighted.Besides,the development trends and outlook are also discussed. | Huaping Wang Sheng Zhu Jiwei Deng Wenchao Zhang Yuezhan Feng Jianmin Ma | 2021 | Chinese Chemical Letters2021，32，1： | 5 |
| 13 | Numerical and experimental studies on solidification of AZ80 magnesium alloy under out-of-phase pulsed magnetic field显示文摘For obtaining the finer grains of magnesium alloy,a novel combined pulsed magnetic field with different initial phases,also called out-ofphase pulsed magnetic field(OPPMF),was applied to study the solidification structure of AZ80 magnesium alloy.The numerical simulation was simultaneously conducted to investigate the refinement mechanisms.The experimental results showed that the macrostructure could be effectively refined by applying external magnetic field.Meanwhile,finer grains were obtained with the higher current intensity.However,the increase of current intensity could only refine the grains to about 0.5 mm.Furthermore,compared to a single pulsed magnetic field(PMF)and alternating series of OPPMF(Connection II),a finer structure was observed when the consecutive series of OPPMF(Connection I)was imposed.In contrast with a single PMF and Connection II,the numerical results showed that the greater axial Lorentz force was obtained under the Connection I,generating the stronger forced flow in the melt.It is believed that abundant nuclei could detach from the mold wall and move faster into the interior melt due to the stronger forced flow;besides,the lower superheat and greater temperature uniformity in bulk melt were realized,accounting for the finest structures under the Connection I. | Wenchao Duan Siqi Yin Wenhong Liu Zhong Zhao Kun Hu Ping Wang Jianzhong Cui Zhiqiang Zhang | 2021 | Journal of Magnesium and Alloys2021，9，1： | 5 |
| 14 | Structuring Nonlinear Wavefront Emitted from Monolayer Transition-Metal Dichalcogenides显示文摘The growing demand for tailored nonlinearity calls for a structure with unusual phase discontinuity that allows the realization of nonlinear optical chirality,holographic imaging,and nonlinear wavefront control.Transition-metal dichalcogenide(TMDC)monolayers offer giant optical nonlinearity within a few-angstrom thickness,but limitations in optical absorption and domain size impose restriction on wavefront control of nonlinear emissions using classical light sources.In contrast,noble metal-based plasmonic nanosieves support giant field enhancements and precise nonlinear phase control,with hundred-nanometer pixellevel resolution;however,they suffer from intrinsically weak nonlinear susceptibility.Here,we report a multifunctional nonlinear interface by integrating TMDC monolayers with plasmonic nanosieves,yielding drastically different nonlinear functionalities that cannot be accessed by either constituent.Such a hybrid nonlinear interface allows second-harmonic(SH)orbital angular momentum(OAM)generation,beam steering,versatile polarization control,and holograms,with an effective SH nonlinearityχ^((2))of~25 nm/V.This designer platform synergizes the TMDC monolayer and plasmonic nanosieves to empower tunable geometric phases and large field enhancement,paving the way toward multifunctional and ultracompact nonlinear optical devices. | Xuanmiao Hong Guangwei Hu Wenchao Zhao Kai Wang Shang Sun Rui Zhu Jing Wu Weiwei Liu Kian Ping Loh Andrew Thye Shen Wee Bing Wang Andrea Alù Cheng-Wei Qiu Peixiang Lu | 2020 | Research2020，，1： | 5 |
| 15 | Photoelectrocatalytic reduction of CO_2 to methanol over a photosystem Ⅱ-enhanced Cu foam/Si-nanowire system显示文摘A solar-light double illumination photoelectrocatalytic cell(SLDIPEC) was fabricated for autonomous CO_2 reduction and O_2 evolution with the aid of photosystem II(PS-II, an efficient light-driven water-oxidized enzyme from nature) and utilized in a photoanode solution. The proposed SLPEC system was composed of Cu foam as the photoanode and p-Si nanowires(Si-NW) as the photocathode. Under solar irradiation, it exhibited a super-photoelectrocatalytic performance for CO_2 conversion to methanol, with a high evolution rate(41.94 mmol/hr), owing to fast electron transfer from PS-II to Cu foam.Electrons were subsequently trapped by Si-NW through an external circuit via bias voltage(0.5 V), and a suitable conduction band potential of Si(-0.6 e V) allowed CO_2 to be easily reduced to CH_3 OH at the photocathode. The constructed Z-scheme between Cu foam and Si-NW can allow the SLDIPEC system to reduce CO_2(8.03 mmol/hr) in the absence of bias voltage. This approach makes full use of the energy band mismatch of the photoanode and photocathode to design a highly efficient device for solving environmental issues and producing clean energy. | Zichao Lian Donglai Pan Wenchao Wang Dieqing Zhang Guisheng Li Hexing Li | 2017 | Journal of Environmental Sciences2017，29，10： | 5 |
| 16 | Expression of the DNA-repair protein XRCC1 and DNA-repair enzyme Ku70 mRNA in the rat cerebral cortex following global cerebral ischemia/reperfusion Is this correlated with neuroprotective effects of theanine?显示文摘BACKGROUND: Numerous studies have shown that apoptosis, caused by cerebral ischemia/reperfusion injury, is a dynamic evolving process that occurs in a time-dependent fashion. Non-apoptotic cells can result in apoptosis, with a prolonged reperfusion period and an accumulation of DNA damage. Recent studies have indicated that theanine has a protective effect on the brain. Nonetheless, there is no research relating to whether theanine is neuroprotective following brain injury. OBJECTIVE: To investigate the effects of theanine on apoptosis in the cerebral cortex and mRNA expression of the DNA repair protein, XRCC1, and DNA repair enzyme, Ku70, at various time points following global cerebral ischemia/reperfusion in rats. DESIGN, TIME AND SETTING: A randomized, controlled animal study was performed at the Pharmacological Laboratory of Animal Experimental Center of Xi'an Jiaotong University, China, from April to October 2007. MATERIALS: Theanine (Wuhan Remote Technology Co., Ltd., China), XRCC1, Ku70 and GAPDH primers (Shanghai Sangon Biological Engineering Technology & Services Co., Ltd., China) were used in this study. METHODS: A total of 108 healthy, male Sprague Dawley rats were randomly divided into sham operation, ischemia/reperfusion and theanine groups. Each group was further divided into 6 sub- groups, with six rats in each, according to reperfusion time (2, 6, 12, 24, 48 and 72 hours). Rat models of global cerebral ischemia/reperfusion were established by the four-vessel occlusion method. Theanine (1 000 mg/kg) was injected into the caudal vein of rats in the theanine group immediately after surgery. Saline (4 mL/kg) was used in the sham operation and ischemia/reperfusion groups. The same dose was administered every 24 hours. MAIN OUTCOME MEASURES: Flow cytometry was employed to determine apoptosis of cerebral cortical neurons. Real-time reverse transcription-polymerase chain reaction was applied to quantify the expression of XRCC1 and Ku70 mRNA in the cerebral cortex. RESULTS: The apoptotic rate in the ischemia/reperfusion group was significantly greater compared with the sham operation group at various time points (P < 0.05). The apoptotic rate in the theanine group was significantly diminished compared with the ischemia/reperfusion group, but significantly increased compared with the sham operation group at 6, 12, 24, 48 and 72 hours (P < 0.05). Ex- pression of XRCC1 and Ku70 mRNA was significantly decreased in the ischemia/reperfusion group compared with the sham operation group at 2, 6, 12, 24, 48 and 72 hours (P < 0.05). The relative expression of XRCC1 mRNA in the theanine group was significantly increased compared with the ischemia/reperfusion group, but significantly reduced compared with the sham operation group at 6, 12, 24, 48 and 72 hours (P < 0.05). The relative expression of Ku70 mRNA was significantly lower in the theanine group compared with the sham operation group at 2, 6 and 12 hours (P < 0.05) and significantly greater than the ischemia/reperfusion group at 6, 12, 24, 48 and 72 hours (P < 0.05). CONCLUSION: The apoptotic rate in rats following global cerebral ischemia/reperfusion injury reaches a peak at 24 hours after reperfusion; however, the levels of DNA repair protein began to decrease after only 2 hours of reperfusion. Theanine antagonizes the decrease in XRCC1 and Ku70 mRNA expression in the rat cerebral cortex during global cerebral ischemia/reperfusion injury. | Rongliang Xue Wenchao Chen Ning Wang Shasha Li | 2010 | Neural Regeneration Research2010，5，1： | 5 |
| 17 | The occurrence of diffuse axonal injury in the brain:associated with the accumulation and clearance of myelin debris显示文摘The accumulation of myelin debris may be a major contributor to the inflammatory response after diffuse axonal injury. In this study, we examined the accumulation and clearance of myelin debris in a rat model of diffuse axonal injury. Oil Red O staining was performed on sections from the cerebral cortex, hippocampus and brain stem to identify the myelin debris. Seven days after diffuse axonal injury, many Oil Red O-stained particles were observed in the cerebral cortex, hippocampus and brain stem. In the cerebral cortex and hippocampus, the amount of myelin debris peaked at 14 days after injury, and decreased significantly at 28 days. In the brain stem, the amount of myelin debris peaked at 7 days after injury, and decreased significantly at 14 and 28 days. In the cortex and hippocampus, some myelin debris could still be observed at 28 days after diffuse axonal injury. Our findings suggest that myelin debris may persist in the rat central nervous system after diffuse axonal injury, which would hinder recovery. | Liang Wen Jun Xu Tianxiang Zhan Hao Wang Xin Huang Wenchao Liu Xiaofeng Yang Renya Zhan | 2014 | Neural Regeneration Research2014，9，21： | 4 |
| 18 | 1 T moderate intensity static magnetic field affects Akt/mTOR pathway and increases the antitumor efficacy of m TOR inhibitors in CNE-2Z cells显示文摘Static magnetic field(SMF) has been known to affect cell proliferation in a cell-type-dependent manner,while the mechanism still remains unclear. We found that 1T moderate intensity SMF inhibits cell proliferation of nasopharyngeal carcinoma CNE-2Z cells and the Akt/m TOR signaling pathway, which is upregulated in many cancers. m TOR inhibitors are potential chemodrugs, but their clinical effects are limited by the feedback reactivation of other signaling components such as EGFR and Akt.We showed that 1 T SMF increases the antitumor efficacy of m TOR inhibitor Torin 2. In addition, 1 T SMF increases the inhibition efficiency on m TOR substrates phosphorylation and represses the m TOR inhibitor-induced feedback reactivation of EGFR and Akt. Our study not only demonstrates that m TOR/Akt pathway is one of the molecular targets of SMFs in cells, but also reveals the clinical potentials of combinations of m TOR inhibitors and SMFs in cancer treatment. | Lei Zhang Xingxing Yang Juanjuan Liu Yan Luo Zhiyuan Li Xinmiao Ji Wenchao Wang Xin Zhang | 2015 | Science Bulletin2015，60，24： | 4 |
| 19 | Nickel and indium core-shell co-catalysts loaded silicon nanowire arrays for efficient photoelectrocatalytic reduction of CO_(2) to formate显示文摘Developing an efficient artificial photosynthetic system for transforming carbon dioxide and storing solar energy in the form of chemical bonds is one of the greatest challenges in modern chemistry.However,the limited choice of catalysts with wide light absorption range,long-term stability and excellent selectivity for CO_(2) reduction makes the process sluggish.Here,a core-shell-structured nonnoble-metal Ni@In co-catalyst loaded p-type silicon nanowire arrays(SiNWs)for efficient CO_(2) reduction to formate is demonstrated.The formation rate and Faradaic efficiency of formate over the Ni@In/SiNWs catalyst reach 58μmol h^(-1) cm^(-2) and 87% under the irradiation of one simulated sunlight(AM 1.5 G,100 mW cm^(-2)),respectively,which are about 24 and 12 times those over the pristine SiNWs.The enhanced photoelectrocatalytic performance for CO_(2) reduction is attributed to the rational combination of Ni capable of effectively extracting the photogenerated electrons and In responsible for the selective activation of CO_(2). | Wenchao Ma Mingcan Xie Shunji Xie Longfu Wei Yichen Cai Qinghong Zhang Ye Wang | 2021 | Journal of Energy Chemistry2021，30，3： | 3 |
| 20 | Excitation-emission matrix (EEM) fluorescence spectroscopy for characterization of organic matter in membrane bioreactors: Principles, methods and applications显示文摘The membrane bioreactor(MBR)technology is a rising star for wastewater treatment.The pollutant elimination and membrane fouling performances of MBRs are essentially related to the dissolved organic matter(DOM)in the system.Three-dimensional excitation-emission matrix(3D-EEM)fluorescence spectroscopy,a powerful tool for the rapid and sensitive characterization of DOM,has been extensively applied in MBR studies;however,only a limited portion of the EEM fingerprinting information was utilized.This paper revisits the principles and methods of fluorescence EEM,and reviews the recent progress in applying EEM to characterize DOM in MBR studies.We systematically introduced the information extracted from EEM by considering the fluorescence peak location/intensity,wavelength regional distribution,and spectral deconvolution(giving fluorescent component loadings/scores),and discussed how to use the information to interpret the chemical compositions,physiochemical properties,biological activities,membrane retention/fouling behaviors,and migration/transformation fates of DOM in MBR systems.In addition to conventional EEM indicators,novel fluorescent parameters are summarized for potential use,including quantum yield,Stokes shift,excited energy state,and fluorescence lifetime.The current limitations of EEM-based DOM characterization are also discussed,with possible measures proposed to improve applications in MBR monitoring. | Jinlan Yu Kang Xiao Wenchao Xue Yue-xiao Shen Jihua Tan Shuai Liang Yanfen Wang Xia Huang | 2020 | Frontiers of Environmental Science & Engineering2020，14，2： | 3 |
