| 1 | Down.regulation of E.cadherin enhances prostate cancer chemoresistance via Notch signaling显示文摘Background:The chemoresistance of prostate cancer(PCa)is invariably associated with the aggressiveness and metastasis of this disease.New emerging evidence indicates that the epithelial-to-mesenchymal transition(EMT)may play pivotal roles in the development of chemoresistance and metastasis.As a hallmark of EMT,E-cadherin is suggested to be a key marker in the development of chemoresistance.However,the molecular mechanisms underlying PCa chemoresistance remain unclear.The current study aimed to explore the association between EMT and chemoresistance in PCa as well as whether changing the expression of E-cadherin would affect PCa chemoresistance.Methods:Parental PC3 and DU145 cells and their chemoresistant PC3-Tx R and DU145-Tx R cells were analyzed.PC3-Tx R and DU145-Tx R cells were transfected with E-cadherin-expressing lentivirus to overexpress E-cadherin;PC3 and DU145 cells were transfected with small interfering RNA to silence E-cadherin.Changes of EMT phenotype-related markers and signaling pathways were assessed by Western blotting and quantitative real-time polymerase chain reaction.Tumor cell migration,invasion,and colony formation were then evaluated by wound healing,transwell,and colony formation assays,respectively.The drug sensitivity was evaluated using MTS assay.Results:Chemoresistant PC3-Tx R and DU145-Tx R cells exhibited an invasive and metastatic phenotype that associated with EMT,including the down-regulation of E-cadherin and up-regulation of Vimentin,Snail,and N-cadherin,comparing with that of parental PC3 and DU145 cells.When E-cadherin was overexpressed in PC3-Tx R and DU145-Tx R cells,the expression of Vimentin and Claudin-1 was down-regulated,and tumor cell migration and invasion were inhibited.In particular,the sensitivity to paclitaxel was reactivated in E-cadherin-overexpressing PC3-Tx R and DU145-Tx R cells.When E-cadherin expression was silenced in parental PC3 and DU145 cells,the expression of Vimentin and Snail was up-regulated,and,particularly,the sensitivity to paclitaxel was decreased.Interestingly,Notch-1 expression was up-regulated in PC3-Tx R and DU145-Tx R cells,whereas the E-cadherin expression was down-regulated in these cells comparing with their parental cells.The use ofγ-secretase inhibitor,a Notch signaling pathway inhibitor,significantly increased the sensitivity of chemoresistant cells to paclitaxel.Conclusion:The down-regulation of E-cadherin enhances PCa chemoresistance via Notch signaling,and inhibiting the Notch signaling pathway may reverse PCa chemoresistance. | Wenchu Wang Lihui Wang Atsushi Mizokami Junlin Shi Chunlin Zou Jinlu Dai Evan T.

| 2 | Evolution of boundary layer ozone in Shijiazhuang,a suburban site on the North China Plain显示文摘The structure of the boundary layer affects the evolution of ozone(O3), and research into this structure will provide important insights for understanding photochemical pollution.In this study, we conducted a one-month observation(from June 15 to July 14, 2016) of the boundary layer meteorological factors as well as O3 and its precursors in Luancheng County,Shijiazhuang(37°53′N, 114°38′E). Our research showed that photochemical pollution in Shijiazhuang is serious, and the mean hourly maximum and mean 8-hr maximum O3 concentrations are 97.9 ± 26.1 and 84.4 ± 22.4 ppbV, respectively. Meteorological factors play a significant role in the formation of O3. High temperatures and southeasterly winds lead to elevated O3 values, and at moderate relative humidity(40%–50%) and medium boundary layer heights(1200–1500 m), O3 production sensitivity occurred in the transitional region between volatile organic compounds(VOC) and nitrogen oxides(NOx) limitations,and the O3 concentration was the highest. The vertical profiles of O3 were also measured by a tethered balloon. The results showed that a large amount of O3 was stored in the residual layer, and the concentration was positively correlated with the O3 concentration measured the previous day. During the daytime of the following day, the contribution of O3 stored in the residual layer to the boundary layer reached 27%± 7% on average. | Wei Zhao Guiqian Tang Huan Yu Yang Yang Yinghong Wang Lili Wang Junlin An Wenkang Gao Bo Hu Mengtian Cheng Xingqin An Xin Li Yuesi Wang | 2019 | Journal of Environmental Sciences2019，31，9： | 15 |
| 3 | Efficient InGaN-based yellow-light-emitting diodes显示文摘Realization of efficient yellow-light-emitting diodes(LEDs) has always been a challenge in solid-state lighting.Great effort has been made, but only slight advancements have occurred in the past few decades. After comprehensive work on InGaN-based yellow LEDs on Si substrate, we successfully made a breakthrough and pushed the wall-plug efficiency of 565-nm-yellow LEDs to 24.3% at 20 A∕cm^2 and 33.7% at 3 A∕cm^2. The success of yellow LEDs can be credited to the improved material quality and reduced compressive strain of InGaN quantum wells by a prestrained layer and substrate, as well as enhanced hole injection by a 3 D pn junction with V-pits. | FENGYI JIANG JIANLI ZHANG LONGQUAN XU JIE DING GUANGXU WANG XIAOMING WU XIAOLAN WANG CHUNLAN MO ZHIJUE QUAN XING GUO CHANGDA ZHENG SHUAN PAN JUNLIN LIU | 2019 | Photonics Research2019，7，2： | 13 |
| 4 | Mixing state of individual carbonaceous particles during a severe haze episode in January 2013,Nanjing,China显示文摘Chemical composition,hourly counts,and sizes of atmospheric carbonaceous particles were measured to investigate their mixing state on clear and hazy days.623,122 carbonaceous particles with sizes0.2-2.0 μm was analyzed using a single-particle aerosol mass spectrometer from 1st to 17 th January2013.Particle types included biomass/biofuel burning particles(biomass),element carbon(EC-dominant)particles that were also mixed with biomass/biofuel burning species(EC-biomass) or secondary species(EC-secondary),organic carbon(OC),internally mixed OC and EC(OCEC),ammonium-containing(ammonium) and sodium-containing(sodium) particles.On clear days the top ranked carbonaceous particle types were biomass(48.2%),EC-biomass(15.7%),OCEC(11.1%),and sodium(9.6%),while on hazy days they were biomass(37.3%),EC-biomass(17.6%),EC-secondary(16.6%),and sodium(12.7%).The fractions of EC-secondary,ammonium(10%),and sodium particle types were elevated on hazy days.Numbers of EC-secondary particles were more than four times those on clear days(4.1%).Thus,carbonaceous particles mixed with ammonium,nitrate and sulfate during aging and transport,enhancing their light extinction effects and hygroscopic growth under high relative humidity on hazy days,further reducing visibility.Our real-time single-particle data showed that changes to mixing state had a significant impact on light extinction during haze events in Nanjing. | Honglei Wang Bin Zhu Zefeng Zhang Junlin An Lijuan Shen | 2015 | Particuology2015，13，3： | 12 |

| 6 | Effects and safety of aspirin use in patients after cerebrovascular bypass procedures显示文摘Object Superficial temporal artery to middle cerebral artery(STA-MCA)bypass is the most effective treatment for Moyamoya disease(MMD).In this study,we aimed to assess whether aspirin improves STA-MCA bypass patency and is safe in patients with MMD.Methods We performed a retrospective medical record review of patients with ischaemic-onset MMD who had undergone STA-MCA bypass at two hospitals between January 2011 and August 2018,to clarify the effects and safety of aspirin following STA-MCA bypass.The neurological status at the last follow-up(FU)was compared between patients with FU bypass patency and occlusion.Results Among 217 identified patients(238 hemispheres),the mean age was 41.4±10.2 years,and 51.8%were male;the indications for STA-MCA bypass were stroke(48.2%),followed by a transient ischaemic attack(44.0%).Immediate bypass patency was confirmed in all cases.During the FU period(1.5±1.5 y),15 cases were occluded at FU imaging,resulting in an overall cumulative patency rate of 94%.The patency rates were 93%and 94%in the short-term FU group(n=131,mean FU time 0.5±0.2 years)and long-term FU group(n=107,mean FU time 4.1±3.5 years),respectively.The STA-MCA bypass patency rate in the aspirin group was higher than that in the non-aspirin group(98.7%vs 89.7%;HR 1.57;95%CI 1.106 to 2.235;p=0.012).No significant difference in the FU haemorrhagic events was observed between the aspirin and non-aspirin groups.Conclusions Among adult patients with ischaemic-onset MMD undergoing STA-MCA bypass procedures,aspirin might increase the bypass patency rate,without increasing the bleeding risk.FU bypass patency may be associated with a better outcome.Additional studies,especially carefully designed prospective studies,are needed to address the role of aspirin after bypass procedures. | Junlin Lu Guangchao Shi Yuanli Zhao Rong Wang Dong Zhang Xiaolin Chen Hao Wang Ji Zong Zhao | 2021 | Stroke & Vascular Neurology2021，6，4： | 7 |
| 7 | Common-anode LED on a Si substrate for beyond 15 Gbit/s underwater visible light communication显示文摘Visible light communication based on light-emitting diodes(LEDs) has become a promising candidate by providing high data rates, low latency, and secure communication for underwater environments. In this paper,a self-designed common-anode GaN-based five-primary-color LED(RGBYC LED) on a Si substrate is proposed and fabricated. The design of a common anode is used to mitigate the saturation effect for a low-frequency component. Additionally, compared with commercially available LEDs that suffer from nonlinearity distortion,applying the designed LED can provide much better and broader linearity according to the measurement results.Therefore, the modulation depth and system performance can be further improved to implement a high-speed underwater visible light communication(UVLC) system. There is no nonlinearity compensation algorithm applied due to the good linearity of the proposed LED;thus, the offline digital signal processing is simplified. We experimentally demonstrate 14.81 Gbit/s 64 quadrature amplitude modulation(QAM)-discrete multitone(DMT)and 15.17 Gbit/s bit-loading-DMT transmissions through a 1.2-m-long underwater channel based on the proposed RGBYC LED with an intrasymbol frequency-domain averaging channel estimation and zero-forcing equalization.As far as we know, this is the highest data rate for an LED-based UVLC system. | YINGJUN ZHOU XIN ZHU FANGCHEN HU JIANYANG SHI FUMIN WANG PENG ZOU JUNLIN LIU FENGYI JIANG NAN CHI | 2019 | Photonics Research2019，7，9： | 7 |
| 8 | Energetic materials based on poly furazan and furoxan structures显示文摘Furazan and furoxan represent fascinating explosophoric units with intriguing structures and unique properties.Compared with other nitrogen-rich heterocycles,most poly furazan and furoxan-based heterocycles demonstrate superior energetic performances due to the higher enthalpy of formation and density levels.A large variety of advanced energetic materials have been achieved based on the combination of furazan and furoxan moieties with different kinds of linkers and this review provides an overview of the development of energetic poly furazan and furoxan structures during the past decades,with their physical properties and detonation characteristics summarized and compa red with traditional energetic materials.Various synthetic strategies towards these compact energetic structures are highlighted by covering the most important cyclization methods for construction of the hetercyclic scaffolds and the following modifications such as nitrations and oxidations.Given the synthetic availabilities and outstanding properties,energetic materials based on poly furazan and furoxan structures are undoubtedly listed as a promising candidate for the development of new-generation explosives,propellants and pyrotechnics. | Junlin Zhang Jing Zhou Fuqiang Bi Bozhou Wang | 2020 | Chinese Chemical Letters2020，31，9： | 6 |
| 9 | Thermal studies of novel molecular perovskite energetic material(C_(6)H_(14)N_(2))[NH_(4)(ClO_(4))_(3)]显示文摘(C6H(14)N2)[NH4(ClO4)3] is a newly developed porous hybrid inorganic-organic framework material with easy access and excellent detonation performances,however,its thermal properties is still unclear and severely hampered further applications.In this study,thermal behaviors and non-isothermal decomposition reaction kinetics of(C6H(14)N2)[NH4(ClO4)3] were investigated systematically by the combination of differential scanning calorimetry(DSC) and simultaneous thermal analysis methods.In-situ FTIR spectroscopy technology was applied for investigation of the structure changes of(C6H(14)N2) NH4(ClO4)3]and some selected referents for better understanding of interactions between different components during the heating process.Experiment results indicated that the novel molecular perovskite structure renders(C6H(14)N2)[NH4(ClO4)3] better thermal stability than most of currently used energetic materials.Underhigh temperature s,the stability of the cage skeleton constructed by NH4^+and ClO4^-ions determined the decomposition process rather than organic moiety confined in the skeleton.The simple synthetic method,good detonation performances and excellent thermal properties make(C6H(14)N2)[NH4(ClO4)3] an ideal candidate for the preparation of advanced explosives and propellants. | Jing Zhou Li Ding Fengqi Zhao Bozhou Wang Junlin Zhang | 2020 | Chinese Chemical Letters2020，31，2： | 5 |
| 10 | Relationships Between Evacuation Population Size, Earthquake Emergency Shelter Capacity, and Evacuation Time显示文摘Determining the location of earthquake emergency shelters and the allocation of affected population to them are key issues that face shelter planning and emergency management. To solve this emergency shelter location–allocation problem, evacuation time and the construction cost of shelters—both influenced by the evacuation population size and its spatial distribution—are two important considerations. In this article, a mathematical model with two objectives—to minimize total weighted evacuation time(TWET) and total shelter area(TSA)—is allied with a modified particle swarm optimization algorithm to address the problem. The relationships between evacuation population size, evacuation time, and total shelter area are examined using Jinzhan Town in Chaoyang District of Beijing, China, as a case study. The results show that TWET has a power function relationship with TSA under different population size scenarios, and a linear function applies between evacuation population and TWET under different TSAs. The joint relationships of TSA, TWET, and population size show that TWET increases with population increase and TSA decrease, and compared with TSA, population influences TWET more strongly. Given a reliable projection of population change and spatial planning of a study area, this method can be useful for government decision making on the location of earthquake emergency shelters and on the allocation of evacuees to those shelters. | Xiujuan Zhao Wei Xu Yunjia Ma Lianije Qin Junlin Zhang Ying Wang | 2017 | International Journal of Disaster Risk Science2017，8，4： | 5 |
| 11 | CXCR4-guided liposomes regulating hypoxic and immunosuppressive microenvironment for sorafenib-resistant tumor treatment显示文摘Clinical sorafenib treatment could activate C-X-C receptor type 4(CXCR4)/stromal source factor-1α(SDF-1α)axis to aggravate intra-tumoral hypoxia of hepatocellular carcinoma(HCC),which further leads to progression,invasion,metastasis,and immunosuppression of tumors and in return causes resistance to sorafenib therapy.Therefore,a multi-functional oxygen delivery nanoplatform was rationally constructed based on an oxygen-saturated perfluorohexane(PFH)-cored liposome,with the CXCR4 antagonist LFC131 peptides modifying on the surface to simultaneously deliver sorafenib and the CSF1/CSF1R inhibitor PLX3397(named PFH@LSLP)for sorafenib-resistant HCC treatment.The PFH@LSLP was developed to overcome sorafenib resistance by syner-gistic effects of the following 3 roles:1)the O_(2)-saturated PFH core could alleviate the tumor hypoxia by O_(2) supply;2)the LFC131 peptide recognized the hypoxia-related overexpressed CXCR4 and then blocked SDF-1α/CXCR4 axis to re-sensitize the HCC cells to sorafenib;3)PLX3397 activated the immune responses via inhibiting the CSF1/CSF1R pathway in TAMs,further enhanced CD8^(+)T cell infiltration to reverse immunosuppression in tumors.Antitumor performance on H22 tumor-bearing mice and HCC patient-derived tumor xenograft(PDX)model showed that PFH@LSLP could overcome sorafenib resistance by synergistic effect of hypoxia attenuation,resistance-related gene regulation,and immune-microenvironment modification. | Yuehua Wang Zhenjie Wang Fei Jia Qing Xu Zhilin Shu Junlin Deng Aimin Li Meng Yu Zhiqiang Yu | 2022 | Bioactive Materials2022，7，11： | 3 |
| 12 | CircRNA expression profiles in decidual tissue of patients with early recurrent miscarriage显示文摘Circular RNAs(circRNAs)are a novel class of endogenous noncoding RNAs that play important roles in gene expression regulation.This study aimed to evaluate the potential role of circRNAs in decidual tissue of patients with early recurrent miscarriage(RM).We constructed circRNA expression profiles in decidual tissue using microarray data.A total of 123 differentially expressed circRNAs,including 78 upregulated and 45 downregulated circRNAs were detected in the early RM group compared with the control group(P<0.05).Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analysis also revealed the enrichment of specific circRNAs.The verified circRNA-targeted miRNA-mRNA network was constructed,most of the circRNAs harbored miRNA binding sites.The network involved 3 circRNAs,27 microRNAs and 82 mRNAs.Hsa_circRNA_103092-miR-224-PRLR network was selected to verify by qRT-PCR.These results showed that circRNAs are aberrantly expressed in the decidual tissue in early RM patients and play potential roles in the development of early RM.It gives new insights into the mechanism of recurrent miscarriage. | Chunli Li Xuemei Chen Xueqing Liu Xiaoli Liu Junlin He Yubin Ding Chao Tong Chuan Peng Yingxiong Wang Rufei Gao | 2020 | Genes & Diseases2020，7，3： | 3 |
| 13 | A novel sparse feature extraction method based on sparse signal via dual-channel self-adaptive TQWT显示文摘Sparse signal is a kind of sparse matrices which can carry fault information and simplify the signal at the same time.This can effectively reduce the cost of signal storage,improve the efficiency of data transmission,and ultimately save the cost of equipment fault diagnosis in the aviation field.At present,the existing sparse decomposition methods generally extract sparse fault characteristics signals based on orthogonal basis atoms,which limits the adaptability of sparse decomposition.In this paper,a self-adaptive atom is extracted by the improved dual-channel tunable Q-factor wavelet transform(TQWT)method to construct a self-adaptive complete dictionary.Finally,the sparse signal is obtained by the orthogonal matching pursuit(OMP)algorithm.The atoms obtained by this method are more flexible,and are no longer constrained to an orthogonal basis to reflect the oscillation characteristics of signals.Therefore,the sparse signal can better extract the fault characteristics.The simulation and experimental results show that the selfadaptive dictionary with the atom extracted from the dual-channel TQWT has a stronger decomposition freedom and signal matching ability than orthogonal basis dictionaries,such as discrete cosine transform(DCT),discrete Hartley transform(DHT)and discrete wavelet transform(DWT).In addition,the sparse signal extracted by the self-adaptive complete dictionary can reflect the time-domain characteristics of the vibration signals,and can more accurately extract the bearing fault feature frequency. | Junlin LI Huaqing WANG Liuyang SONG | 2021 | Chinese Journal of Aeronautics2021，34，7： | 2 |
| 14 | Characteristics of black carbon aerosol in Jiaxing,China during autumn 2013显示文摘We conducted measurements of black carbon(BC) aerosol in Jiaxing,China during autumn from September 26 to November 30,2013.We investigated temporal and diurnal variations of BC,and its correlations with meteorological parameters and other major pollutants.Results showed that hourly mass concentrations of BC ranged from 0.2 to 22.0 μg/m^3,with an average of 5.1 μg/m^3.The diurnai variation of BC exhibited a bimodal distribution,with peaks at 07:00 and 18:00.The morning peak was larger than the evening peak.The mass percentages of BC in PM_(2.5) and PM_(10) were 7.1%and 4.8%,respectively.The absorption coefficient of BC was calculated to be 44.4 Mm^(-1),which accounted for 11.1%of the total aerosol extinction.BC was mainly emitted from local sources in southwestern Jiaxing where BC concentrations were generally greater than 11 μg/m^3 during the measurement period.Correlation analysis indicated that the main sources of BC were motor vehicle exhaust,and domestic and industrial combustion. | Lijuan Shen Li Li Sheng Lu Xiaohan Zhang Jie Liu Junlin An Guojun Zhang Bo Wu Fei Wang | 2015 | Particuology2015，13，3： | 2 |

| 16 | Numerical study of collection efficiency and heat-transfer characteristics of packed granular filter显示文摘The collection mechanism and heat-transfer characteristics of a packed granular filter were investigated using a three-dimensional randomly packed granular filter model. The bridging method was introduced to optimize the grids of contact points between granules. The influences of granular bed depth, gas velocity, and gas temperature on grade collection efficiency were investigated. The results indicated that a decrease of temperature improved collection efficiency when the particle diameter was greater than 5 |xm. The grade collection efficiency maintained a stable value when the Stokes number, St, was less than 0.009, but increased linearly with ig(St) when St > 0.009. A logarithmic mean temperature difference method was used to obtain overall heat-transfer coefficients of gas-solid two-phase flow through the packed granular filter. The results showed that convective heat transfer was enhanced due to the intro-duction of solid particles in the bed. The overall heat-transfer coefficient increased approximately linearly with an increase in particle loading ratio. The Nusselt number was related to the Reynolds number, the Archimedes number, and the particle loading ratio. | Junlin Chen Xunfeng Li Xiulan Huai Yongwei Wang Jingzhi Zhou | 2019 | Particuology2019，17，5： | 2 |

| 18 | High-performance RF Switch in 0.13 μm RF SOI process显示文摘A high-performance single-pole single-throw(SPST) RF switch for mobile phone RF front-end modules(FEMs) was designed and characterized in a 0.13 μm partially depleted silicon-on-insulator(PD SOI) process. In this paper, the traditional seriesshunt configuration design was improved by introducing a suitably large DC bias resistor and leakage-preventing PMOS, together with the floating body technique. The performance of the RF switch is greatly improved. Furthermore, a new Ron × Coff testing method is also proposed. The size of this SPST RF switch is 0.2 mm2. This switch can be widely used for present 4 G and forthcoming 5 G mobile phone FEMs. | Hong Guan Hao Sun Junlin Bao Zhipeng Wang Shuguang Zhou Hongwei Zhu | 2019 | Journal of Semiconductors2019，40，2： | 2 |
| 19 | Biomarkers of aging显示文摘Aging biomarkers are a combination of biological parameters to(i)assess age-related changes,(ii)track the physiological aging process,and(iii)predict the transition into a pathological status.Although a broad spectrum of aging biomarkers has been developed,their potential uses and limitations remain poorly characterized.An immediate goal of biomarkers is to help us answer the following three fundamental questions in aging research:How old are we?Why do we get old?And how can we age slower?This review aims to address this need.Here,we summarize our current knowledge of biomarkers developed for cellular,organ,and organismal levels of aging,comprising six pillars:physiological characteristics,medical imaging,histological features,cellular alterations,molecular changes,and secretory factors.To fulfill all these requisites,we propose that aging biomarkers should qualify for being specific,systemic,and clinically relevant. | Aging Biomarker Consortium Hainan Bao Jiani Cao Mengting Chen Min Chen Wei Chen Xiao Chen Yanhao Chen Yu Chen Yutian Chen Zhiyang Chen Jagadish K Chhetri Yingjie Ding Junlin Feng Jun Guo Mengmeng Guo Chuting He Yujuan Jia Haiping Jiang Ying Jing Dingfeng Li Jiaming Li Jingyi Li Qinhao Liang Rui Liang Feng Liu Xiaoqian Liu Zuojun Liu Oscar Junhong Luo Jianwei Lv Jingyi Ma Kehang Mao Jiawei Nie Xinhua Qiao Xinpei Sun Xiaoqiang Tang Jianfang Wang Qiaoran Wang Siyuan Wang Xuan Wang Yaning Wang Yuhan Wang Rimo Wu Kai Xia Fu-Hui Xiao Lingyan Xu Yingying Xu Haoteng Yan Liang Yang Ruici Yang Yuanxin Yang Yilin Ying Le Zhang Weiwei Zhang Wenwan Zhang Xing Zhang Zhuo Zhang Min Zhou Rui Zhou Qingchen Zhu Zhengmao Zhu Feng Cao Zhongwei Cao Piu Chan Chang Chen Guobing Chen Hou-Zao Chen Jun Chen Weimin Ci Bi-Sen Ding Qiurong Ding Feng Gao Jing-Dong JHan Kai Huang Zhenyu Ju Qing-Peng Kong Ji Li Jian Li Xin Li Baohua Liu Feng Liu Lin Liu Qiang Liu Qiang Liu Xingguo Liu Yong Liu Xianghang Luo Shuai Ma Xinran Ma Zhiyong Mao Jing Nie Yaojin Peng Jing Qu Jie Ren Ruibao Ren Moshi Song Zhou Songyang Yi Eve Sun Yu Sun Mei Tian Shusen Wang Si Wang Xia Wang Xiaoning Wang Yan-Jiang Wang Yunfang Wang Catherine CL Wong Andy Peng Xiang Yichuan Xiao Zhengwei Xie Daichao Xu Jing Ye Rui Yue Cuntai Zhang Hongbo Zhang Liang Zhang Weiqi Zhang Yong Zhang Yun-Wu Zhang Zhuohua Zhang Tongbiao Zhao Yuzheng Zhao Dahai Zhu Weiguo Zou Gang Pei Guang-Hui Liu | 2023 | Science China(Life Sciences)2023，66，5： | 2 |
| 20 | Analysis of the Effect of Optical Properties of Black Carbon on Ozone in an Urban Environment at the Yangtze River Delta,China显示文摘Black carbon(BC)reduces the photolysis coefficient by absorbing solar radiation,thereby affecting the concentration of ozone(O_(3))near the ground.The influence of BC on O_(3)has thus received much attention.In this study,Mie scattering and the tropospheric Ultraviolet and Visible radiation model are used to analyze the effect of BC optical properties on radiation.Combined with data of O_(3)precursors in Nanjing in 2014,an EKMA curve is drawn,and the variations in O_(3)concentration are further investigated using a zero-dimensional box mechanism model(NCAR MM).When O_(3)precursors are unchanged,radiation and O_(3)show a highly similar tendency in response to changing BC optical properties(R=0.997).With the increase of modal radius,the attenuation of fresh BC to radiation and O_(3)first trends upward before decreasing.In the mixing process,the attenuation of BC to radiation and O_(3)presents an upward tendency with the increase of relative humidity but decreases rapidly before increasing slowly with increasing thickness of coating.In addition,mass concentration is another major factor.When the BC to PM_(2.5)ratio increases to 5%in Nanjing,the radiation decreases by approximately 0.13%-3.71%while O_(3)decreases by approximately 8.13%-13.11%.The radiative effect of BC not only reduces O_(3)concentration but also changes the EKMA curve.Compared with the NO_(x)control area,radiation has a significant influence on the VOCs control area.When aerosol optical depth(AOD)increases by 17.15%,the NO_(x)to VOCs ratio decreases by 8.27%,and part of the original NO_(x)control area is transferred to the VOCs control area. | Junlin AN Huan LV Min XUE Zefeng ZHANG Bo HU Junxiu WANG Bin ZHU | 2021 | Advances in Atmospheric Sciences2021，38，7： | 1 |
