| 1 | Characterization of personal exposure concentration of fine particles for adults and children exposed to high ambient concentrations in Beijing, China显示文摘In China, the health risk from overexposure to particles is becoming an important public health concern. To investigate daily exposure characteristics to PM 2.5 with high ambient concentration in urban area, a personal exposure study was conducted for school children, and office workers in Beijing, China. For all participants (N = 114), the mean personal 24-hr exposure concentration was 102.5, 14.7, 0.093, 0.528, 0.934, 0.174 and 0.703 μg/m 3 for PM 2.5 , black carbon, Mn, Al, Ca, Pb, and Fe. Children's exposure concentrations of PM 2.5 were 4-5 times higher than those in related studies. The ambient concentration of PM 2.5 (128.5 μg/m 3 ) was significantly higher than the personal exposure concentration (P < 0.05), and exceed the reference concentration (25 μg/m 3 ) of WHO air quality guideline. Good correlation relationships and significant differences were identified between ambient concentration and personal exposure concentration. The relationships indicate that the ambient concentration is the main factor influencing personal exposure concentration, but is not a good indicator of personal exposure concentration. Outdoor activities (commute mode, exposure to heating, workday or weekend travel) influenced personal exposure concentrations significantly, but the magnitude of the influence from indoor activities (exposure to cooking) was masked by the high ambient concentrations. | Xuan Du Qian Kong Weihua Ge Shaojun Zhang Lixin Fu | 2010 | Journal of Environmental Sciences2010,22,11: | 24 |

| 5 | Spatial and Temporal Distributions and Sources of Anthropogenic NMVOCs in the Atmosphere of China:A Review显示文摘As the key precursors of O_(3),anthropogenic non-methane volatile organic compounds(NMVOCs)have been studied intensively.This paper performed a meta-analysis on the spatial and temporal variations of NMVOCs,their roles in photochemical reactions,and their sources in China,based on published research.The results showed that both nonmethane hydrocarbons(NMHCs)and oxygenated VOCs(OVOCs)in China have higher mixing ratios in the eastern developed cities compared to those in the central and western areas.Alkanes are the most abundant NMHCs species in all reported sites while formaldehyde is the most abundant among the OVOCs.OVOCs have the highest mixing ratios in summer and the lowest in winter,which is opposite to NMHCs.Among all NMVOCs,the top eight species account for 50%−70%of the total ozone formation potential(OFP)with different compositions and contributions in different areas.In devolved regions,OFP-NMHCs are the highest in winter while OFP-OVOCs are the highest in summer.Based on positive matrix factorization(PMF)analysis,vehicle exhaust,industrial emissions,and solvent usage in China are the main sources for NMHCs.However,the emission trend analysis showed that solvent usage and industrial emissions will exceed vehicle exhaust and become the two major sources of NMVOCs in near future.Based on the meta-analysis conducted in this work,we believe that the spatio-temporal variations and oxidation mechanisms of atmospheric OVOCs,as well as generating a higher spatial resolution of emission inventories of NMVOCs represent an area for future studies on NMVOCs in China. | Fanglin WANG Wei DU Shaojun LV Zhijian DING Gehui WANG | 2021 | Advances in Atmospheric Sciences2021,38,7: | 4 |
| 6 | The E3 Ubiquitin Ligase gp78 Protects against ER Stress in Zebrafish Liver显示文摘Enhanced endoplasmic reticulum(ER)-associated protein degradation(ERAD) activity by the unfolded protein response(UPR) represents one of the mechanisms for restoring ER homeostasis.In vitro evidence indicates that the mammalian gp78 protein is an E3 ubiquitin ligase that facilitates ERAD by polyubiquitinating and targeting proteins for proteasomal degradation under both physiologic and stress conditions.However,the in vivo function of gp78 in maintaining ER protein homeostasis remains untested.Here we show that like its mammalian counterpart,the zebrafish gp78 is also an E3 ubiquitin ligase as revealed by in vitro ubiquitination assays.Expression analysis uncovered that gp78 is highly expressed in several organs,including liver and brain,of both larval and adult fish.Treatment of larvae or adult fish with tunicamycin induces ER stress and upregulates the expression of several key components of the gp78 ERAD complex in the liver.Moreover,liver-specific overexpression of the dominant-negative form of gp78(gp78-R2M) renders liver more sensitive to tunicamycin-induced ER stress and enhances the expression of sterol response element binding protein(Srebp)-target genes,which was largely suppressed in fish overexpressing wild-type gp78.Together,these data indicate that gp78 plays a critical role in protecting against ER stress in liver. | Zhiliang Chen Petek Ballar Yu Fu Jia Luo Shaojun Du Shengyun Fang | 2014 | Journal of Genetics and Genomics2014,41,7: | 3 |

| 8 | Different role of second phase in the micro-galvanic corrosion of WE43 Mg alloy in NaCl and Na_(2)SO_(4) solution显示文摘Effect of the second phase in the micro-galvanic corrosion of a commercial Mg alloy containing rare earth elements, cast WE43 alloy,was investigated in 0.6 M NaCl solution and 0.6 M Na_(2)SO_(4)solution by scanning electron microscopy(SEM) observations, scanning Kelvin probe force microscopy(SKPFM) analysis, hydrogen evolution, weight loss measurement, and electrochemical techniques. It is confirmed that the second phase of cast WE43 alloy is more active than Mg matrix and exhibits an anodic role in the micro-galvanic corrosion with α-Mg matrix as cathode and dissolves preferentially in Na_(2)SO_(4)solution, in contrast to the situation in NaCl solution. The corrosion rate of cast WE43 alloy in Na_(2)SO_(4)solution is much higher than that in NaCl solution, which is different from the conventional wisdom and could be attributed to the different role of the second phase in the micro-galvanic corrosion in two solutions. | Baojing Feng Guonan Liu Peixu Yang Sensen Huang Dongqing Qi Peng Chen Chengduo Wang Jiang Du Shaojun Zhang Jinhui Liu | 2022 | Journal of Magnesium and Alloys2022,10,6: | 2 |
| 9 | Smyd1 is essential for myosin expression and sarcomere organization in craniofacial,extraocular,and cardiac muscles显示文摘Skeletal and cardiac muscles are striated myofibers that contain highly organized sarcomeres for muscle contraction.Recent studies revealed that Smyd1,a lysine methyltransferase,plays a key role in sarcomere assembly in heart and trunk skeletal muscles.However,Smyd1 expression and function in craniofacial muscles are not known.Here,we analyze the developmental expression and function of two smyd1 paralogous genes,smyd1 a and smyd1 b,in craniofacial and cardiac muscles of zebrafish embryos.Our data show that loss of smyd1a(smyd1a^(mb5))or smyd1b(smyd1b^(sa15678))has no visible effects on myogenic commitment and expression of myod and myosin heavy-chain m RNA transcripts in craniofacial muscles.However,myosin heavy-chain protein accumulation and sarcomere organization are dramatically reduced in smyd1b^(sa15678) single mutant,and almost completely diminish in smyd1a^(mb5);smyd1b^(sa15678) double mutant,but not in smyd1a^(mb5) mutant.Similar defects are also observed in cardiac muscles of smyd1b^(sa15678) mutant.Defective craniofacial and cardiac muscle formation is associated with an upregulation of hsp90α1 and unc45b mRNA expression in smyd1b^(sa15678) and smyd1a^(mb5);smyd1b^(sa15678) mutants.Together,our studies indicate that Smyd1b,but not Smyd1a,plays a key role in myosin heavy-chain protein expression and sarcomere organization in craniofacial and cardiac muscles.Loss of smyd1b results in muscle-specific stress response. | Shuang Jiao Rui Xu Shaojun Du | 2021 | Journal of Genetics and Genomics2021,48,3: | 2 |
| 10 | Ammonia in urban atmosphere can be substantially reduced by vehicle emission control:A case study in Shanghai, China显示文摘To investigate the impact of emission controls on ammonia(NH_(3)) pollution in urban atmosphere, observation on NH_(3)(1 hr interval) was performed in Shanghai before, during and after the 2019 China International Import Expo (CIIE) event, along with measurements on inorganic ions, organic tracers and stable nitrogen isotope compositions of ammonium in PM_(2.5). NH_(3)during the CIIE period was 6.5±1.0μg/m^(3), which is 41% and 32% lower than that before and after the event, respectively. Such a decrease was largely ascribed to the emission controls in nonagricultural sources, of which contribution for measured NH_(3)in control phase abated by ~20% compared to that during uncontrol period. Molecular compositions of PAHs and hopanes further suggested a dominant role of the reduced vehicle emissions in the urban NH_(3)abatement during the CIIE period. Our results revealed that vehicle exhaust emission control is an effective way to mitigate NH_(3)pollution and improve air quality in Chinese urban areas. | Can Wu Shaojun Lv Fanglin Wang Xiaodi Liu Jin Li Lang Liu Si Zhang Wei Du Shijie Liu Fan Zhang Jianjun Li Jingjing Meng Gehui Wang | 2023 | Journal of Environmental Sciences2023,,4: | 1 |

| 12 | Significant coal combustion contribution to water-soluble brown carbon during winter in Xingtai, China: Optical properties and sources显示文摘To understand the characteristics of atmospheric brown carbon(BrC),daily PM2.5 samples in Xingtai,a small city in North China Plain(NCP),during the four seasons of 2018-2019,were collected and analyzed for optical properties and chemical compositions.The light absorption at 365 nm(abs λ=365 nm)displayed a strong seasonal variation with the highest value in winter(29.0±14.3 M/m),which was 3.2∼5.4-fold of that in other seasons.A strong correlation of abs λ=365 nm with benzo(b)fluoranthene(BbF)was only observed in winter,indicating that coal combustion was the major source for BrC in the season due to the enhanced domestic heating.The mass absorbing efficiency of BrC also exhibited a similar seasonal pattern,and was found to correlate linearly with the aerosol pH,suggesting a positive effect of aerosol acidity on the optical properties and formation of BrC in the city.Positive matrix factorization(PMF)analysis further showed that on a yearly basis the major source for BrC was biomass burning,which accounted for 34% of the total BrC,followed by secondary formation(26.7%),coal combustion(21.3%)and fugitive dust(18%).However,the contribution from coal combustionwas remarkably enhanced in winter,accounting for∼40%of the total.Our work revealed that more efforts of“shifting coal to clean energy”are necessary in rural areas and small cities in NCP in order to further mitigate PM2.5 pollution in China. | Dapeng Li Can Wu Si Zhang Yali Lei Shaojun Lv Wei Du Shijie Liu Fan Zhang Xiaodi Liu Lang Liu Jingjing Meng Yuesi Wang Jian Gao Gehui Wang | 2023 | Journal of Environmental Sciences2023,,2: | 1 |

| 17 | Smart heat isolator with hollow multishelled structures显示文摘Safe, green and efficient industrial production has always been the pursuit of the chemical industry. Since thermal energy is the driving force for most of chemical reactions, an ideal reaction tank would have the capacity to automatically regulate heat conduction rate. In detail, this reaction tank should endow an ability that resists the heat loss when the reaction temperature is lower than the target, while accelerating the heat dissipation when the system is overheated. In this case, this smart reactor can not only minimize energy consumption but also reduce safety risks.Hollow structures are known to reduce heat conductivity. Particularly, the hollow structure with multishells can provide more interfaces and thus further inhibit heat transmission, which would be more favorable for heat isolation. Step forward, by coupling HoMSs with temperature-sensitive polymer, a smart heat isolation material has been fabricated in this work. It performs as a good heat isolator at a relatively lower temperature. A heat insulation effect of 6.5℃ can be achieved for the TSPU/3S–TiO_(2)HoMSs with a thickness of 1 mm under the temperature field of 50℃.The thermal conductivity of composite material would be raised under overheating conditions. Furthermore, this composite displays an unusual two-stage phase transformation during heating. Benefiting from the unique multishelled structure, energy is found to be gradually guided into the hollow structure and stored inside. This localized heat accumulation enables the composite to be a potential coating material for intelligent thermal-regulator and site-defined micro-reactor. | Kun Wang Lekai Xu Jiao Wang Shaojun Zhang Yanlei Wang Nailiang Yang Jiang Du Dan Wang | 2023 | Green Energy & Environment2023,8,4: | 0 |
| 18 | A highly efficient atomically thin curved Pd Ir bimetallene electrocatalyst显示文摘The multi-metallene with an ultrahigh surface area has great potential in precise tuning of surface heterogeneous d-electronic correlation by surface strain effect for the distinctive surface electronic structure,which is a brand new class of promising 2 D electrocatalyst for sustainable energy device application.However,achieving such an atomically thin multi-metallene still presents a great challenge.Herein,we present a new synthetic method for an atomic-level palladium-iridium(Pd Ir)bimetallene with an average thickness of only~1.0 nm for achieving superior catalysis in the hydrogen evolution reaction(HER)and the formic acid oxidation reaction(FAOR).The curved Pd Ir bimetallene presents a top-ranked high electrochemical active area of 127.5±10.8 m^(2)g Pd+Ir^(-1)in the reported noble alloy materials,and exhibits a very low overpotential,ultrahigh activity and improved stability for HER and FAOR.DFT calculation reveals that the Pd Ir bimetallene herein has a unique lattice tangential strain,which can induce surface distortion while concurrently creating a variety of concave-convex featured micro-active regions formed by variously coordinated Pd sites agglomeration.Such a strong strain effect correlates the abnormal on-site active 4 d^(10)-t_(2g)-orbital Coulomb correlation potential and directly elevates orbital-electronegativity exposure within these active regions,resulting in a preeminent barrier-free energetic path for significant enhancement of FAOR and HER catalytic performance. | Fan Lv Bolong Huang Jianrui Feng Weiyu Zhang Kai Wang Na Li Jinhui Zhou Peng Zhou Wenxiu Yang Yaping Du Dong Su Shaojun Guo | 2021 | National Science Review2021,8,9: | 0 |
| 19 | Low molecular weight protein phosphatase APH mediates tyrosine dephosphorylation and ABA response in Arabidopsis.显示文摘Low molecular weight protein tyrosine phosphatase(LWM-PTP),also known as acid phosphatase,is a highly conserved tyrosine phosphatase in living organisms.However,the function of LWM-PTP homolog has not been reported yet in plants.Here,we revealed a homolog of acid phosphatase,APH,in Arabidopsis plants,is a functional protein tyrosine phosphatase.The aph mutants are hyposensitive to ABA in post-germination growth.We performed an anti-phosphotyrosine antibody-based quantitative phosphoproteomics in wild-type and aph mutant and identified hundreds of putative targets of APH,including multiple splicing factors and other transcriptional regulators.Consistently,RNA-seq analysis revealed that the expression of ABA-highly-responsive genes is suppressed in aph mutants.Thus,APH regulates the ABA-responsive gene expressions by regulating the tyrosine phosphorylation of multiple splicing factors and other post-transcriptional regulators.We also revealed that Tyr383 in RAF9,a member of B2 and B3 RAF kinases that phosphorylate and activate SnRK2s in the ABA signaling pathway,is a direct target site of APH.Phosphorylation of Tyr383 is essential for RAF9 activity.Our results uncovered a crucial function of APH in ABA-induced tyrosine phosphorylation in Arabidopsis. | Yanyan Du Shaojun Xie Yubei Wang Yu Ma Bei Jia Xue Liu Jingkai Rong Rongxia Li Xiaohong Zhu Chun-Peng Song WAndy Tao Pengcheng Wang | 2022 | Stress Biology2022,2,1: | 0 |
| 20 | Particulate Amines in the Background Atmosphere of the Yangtze River Delta,China:Concentration,Size Distribution,and Sources显示文摘Amines are important for new particle formation and subsequent growth in the atmosphere.Consequently,the processes involved are receiving more attention in recent years.Here,we conduct a field observation in order to investigate the atmospheric particulate amines at a background site in the Yangtze River Delta(YRD)during the summer of 2018.Four amines in PM_(2.5),i.e.,methylamine(MA),dimethylamine(DMA),diethylamine(DEA),and trimethylamine(TMA),were collected,twice daily and analyzed.During the campaign,our measurements found the concentrations of MA,DMA,DEA,and TMA of 15.0±15.0,6.3±6.9,20.4±30.1,and 4.0±5.9 ng m^-(3),respectively,and the four amines correlated well with each other.The concentration of amines appear to be independent of whether they were collected during the day or night.Both MA and DMA exhibited a bimodal size distribution that had peaks at 0.67 and 1.1μm,suggesting amines preferably distribute on submicron particles.Boundary layer height(BLH),relative humidity,and pH of aerosols were found have a negative relationship with amines,while aerosol liquid water content(ALWC)was found to have a positive relationship with amines.The PMF(positive matrix factorization)source apportionment results showed that the main source of amines in Chongming Island was of anthropogenic origin such as industrial and biomass emission,followed by marine sources including sea salt and marine biogenic sources.Given that the YRD region is still suffering from complex atmospheric pollution and that the knowledge on aerosol amines is still limited,more field studies are in urgent need for a better understanding of the pollution characteristics of amines. | Wei DU Xinpei WANG Fengqin YANG Kaixu BAI Can WU Shijie LIU Fanglin WANG Shaojun LV Yubao CHEN Jinze WANG Wenliang LIU Lujun WANG Xiaoyong CHEN Gehui WANG | 2021 | Advances in Atmospheric Sciences2021,38,7: | 0 |
