| 1 | Characteristics of atmospheric single particles during haze periods in a typical urban area of Beijing:A case study in October,2014显示文摘To investigate the composition and possible sources of particles, especially during heavy haze pollution, a single particle aerosol mass spectrometer(SPAMS) was deployed to measure the changes of single particle species and sizes during October of 2014, in Beijing. A total of 2,871,431 particles with both positive and negative spectra were collected and characterized in combination with the adaptive resonance theory neural network algorithm(ART-2a). Eight types of particles were classified: dust particles(dust, 8.1%), elemental carbon(EC, 29.0%), organic carbon(OC, 18.0%), EC and OC combined particles(ECOC, 9.5%),Na-K containing particles(Na K, 7.9%), K-containing particles(K, 21.8%), organic nitrogen and potassium containing particles(KCN, 2.3%), and metal-containing particles(metal,3.6%). Three haze pollution events(P1, P2, P3) and one clean period(clean) were analyzed,based on the mass and number concentration of PM_(2.5)and the back trajectory results from the hybrid single particle Lagrangian integrated trajectory model(Hysplit-4 model). Results showed that EC, OC and K were the major components of single particles during the three haze pollution periods, which showed clearly increased ratios compared with those in the clean period. Results from the mixing state of secondary species of different types of particles showed that sulfate and nitrate were more readily mixed with carbon-containing particles during haze pollution episodes than in clean periods. | Lang Liu Yanli Wang Shiyong Du Wenjie Zhang Lujian Hou Sverre Vedal Bin Han Wen Yang Mindong Chen Zhipeng Bai | 2016 | Journal of Environmental Sciences2016，28，2： | 19 |

The process parameters including the concentrations of PTFE emulsion, particle size of catalyst and calcination temperature for preparation of catalytic filters were analyzed. In addition, the physical properties and performance for removal of NO(NH_3-SCR) and particulates of Mn-Ce-Nb-O_x/P84 catalytic filter prepared under the optimized parameters, were also systematic studied. Results show that the process parameters had significant influences on stability and performance of catalytic filter, The Mn-Ce-Nb-O_x/P84 catalytic filter prepared by foam coating method under the optimized parameters, has satisfactory physical properties and catalytic performance for removal of NO and particulates at 140-220 ℃. The NO removal efficiency of catalytic filter can reach95.3% at 200 ℃ as the catalyst loading amount is 450 g/m^2, Moreover,the dust removal efficiency of MnGe-Nb-O_x/P84 catalytic filter reaches as high as 99.98%, and the PM2.5 removal efficiency also reaches99.98%. The anti-sulfur performance of Mn-Ce-Nb-O_x catalytic filter is also attractive, after injecting150 ppm SO_2, the NO removal efficiency still retains up to 85%. It is indicated that the foam coating method can not only make a bond of high strength between catalyst and filter, but also make the catalytic filter possessing an excellent and stable performance for removal of NO and particulates. | Bo Yang Qiong Huang Mindong Chen Yuesong Shen Shemin Zhu | 2019 | Journal of Rare Earths2019，37，3： | 10 |

| 4 | Full time-domain nonlinear coupled dynamic analysis of a truss spar and its mooring/riser system in irregular wave显示文摘A new full time-domain nonlinear coupled method has been established and then applied to predict the responses of a Truss Spar in irregular wave.For the coupled analysis,a second-order time-domain approach is developed to calculate the wave forces,and a finite element model based on rod theory is established in three dimensions in a global coordinate system.In numerical implementation,the higher-order boundary element method(HOBEM)is employed to solve the velocity potential,and the 4th-order Adams-Bashforth-Moultn scheme is used to update the second-order wave surface.In deriving convergent solutions,the hull displacements and mooring tensions are kept consistent at the fairlead and the motion equations of platform and mooring-lines/risers are solved simultaneously using Newmark-integration scheme including Newton-Raphson iteration.Both the coupled quasi-static analysis and the coupled dynamic analysis are performed.The numerical simulation results are also compared with the model test results,and they coincide very well as a whole.The slow-drift responses can be clearly observed in the time histories of displacements and mooring tensions.Some important characteristics of the coupled responses are concluded. | YANG MinDong TENG Bin XIAO LongFei NING DeZhi SHI ZhongMin QU Yan | 2014 | Science China(Physics,Mechanics & Astronomy)2014，57，1： | 8 |
| 5 | Synergetic catalytic removal of chlorobenzene and NOχfrom waste incineration exhaust over MnNb0.4Ce0.2Oχcatalysts:Performance and mechanism study显示文摘Nb doped MnCe0.2Ox complex oxides catalysts prepared via a homogeneous precipitation method were investigated for synergistic catalytic removal of NOx and chlorobenzene(CB)at low temperatures.The MnNb0.4Ce0.2Ox catalyst with a molar ratio of Nb/Mn=0.4 exhibits excellent activity and the NOx and CB removal efficiency reaches 94.5%and 96%at 220℃,respectively.Furthermore,the NOx and CB removal efficiency of MnNb0.4Ce0.2Ox still remains above 80%after injecting 300 ppm SO2 and 7 vol%H2 O for 36 h.In addition,the presence of CB and NOx+NH3 can improve the NOx and CB removal efficiency of MnNb0.4Ce0.2Ox,respectively.The analysis results from N2-BET,Py-IR,H2-TPR and NH3-TPD reveal that the introduction of Nb increases the average pore size,pore volume and surface area,promoted the growth of Lewis acid amount obviously,and enhances redox ability of MnCe0.2Ox at 100-250℃.Moreover,the molecular migration process of NOx,NH3,CB and SO2 in NH3-SCR and CB oxidation reaction over MnNb0.4Ce0.2Ox catalysts were systematically studied.In situ DRIFTS,FT-IR and XPS also confirm that the adsorption of sulfate species and SO2 on the surface of MnNb0.4Ce0.2Ox is inhibited effectively by the introduction of Nb in the presence of SO2 and H2 O.Moreover,Nb additives also enhance the structural stability of MnNb0.4Ce0.2Ox,due to the interactions among Mn,Nb and Ce.The NH3-TPD,H2-TPR and in situ DRIFTS results also confirm that the MnNb0.4Ce0.2Ox still retains abundant acid sites and high redox ability in the presence of SO2 and H2O.In summary,MnNb0.4Ce0.2Ox catalysts represent a promising and effective candidate for controlling NOx and CB at low temperatures. | Bo Yang Qijie Jin Qiong Huang Mindong Chen Leilei Xu Yuesong Shen Haitao Xu Shemin Zhu Xiujun Li | 2020 | Journal of Rare Earths2020，38，11： | 6 |
| 6 | An intensive study on aerosol optical properties and affecting factors in Nanjing,China显示文摘The optical properties of aerosol as well as their impacting factors were investigated at a suburb site in Nanjing during autumn from 14 to 28 November 2012. More severe pollution was found together with lower visibility. The average scattering and absorption coefficients(B sca and B abs) were 375.7 ± 209.5 and 41.6 ± 18.7 Mm^(-1), respectively. Higher ?ngstr?m absorption and scattering exponents were attributed to the presence of more aged aerosol with smaller particles. Relative humidity(RH) was a key factor affecting aerosol extinction. High RH resulted in the impairment of visibility, with hygroscopic growth being independent of the dry extinction coefficient. The hygroscopic growth factor was 1.8 ± 1.2 with RH from 19% to 85%.Light absorption was enhanced by organic carbon(OC), elemental carbon(EC) and EC coatings,with contributions of 26%, 44% and 75%(532 nm), respectively. The B sca and B abs increased with increasing N_(100)(number concentration of PM_(2.5)with diameter above 100 nm), PM_1 surface concentration and PM_(2.5)mass concentration with good correlation. | Fenping Cui Mindong Chen Yao Ma Jun Zheng Zhou Yaoyao Shizheng Li Lu Qi Li Wang | 2016 | Journal of Environmental Sciences2016，28，2： | 6 |

| 8 | Gravimetric analysis for PM_(2.5) mass concentration based on year-round monitoring at an urban site in Beijing显示文摘Daily PM_(2.5)(particulate matter with an aerodynamic diameter of below 2.5 μm) mass concentrations were measured by gravimetric analysis in Chinese Research Academy of Environmental Sciences(CRAES), in the northern part of the Beijing urban area, from December 2013 to April 2015. Two pairs of Teflon(T1/T2) and Quartz(Q1/Q2) samples were obtained, for a total number of 1352 valid filters. Results showed elevated pollution in Beijing,with an annual mean PM_(2.5)mass concentration of 102 μg/m^3. According to the calculated PM_(2.5)mass concentration, 50% of our sampling days were acceptable(PM_(2.5)< 75 μg/m^3), 30% had slight/medium pollution(75–150 μg/m^3), and 7% had severe pollution(> 250 μg/m^3). Sampling interruption occurred frequently for the Teflon filter group(75%) in severe pollution periods,resulting in important data being missing. Further analysis showed that high PM_(2.5)combined with high relative humidity(RH) gave rise to the interruptions. The seasonal variation of PM_(2.5)was presented, with higher monthly average mass concentrations in winter(peak value in February, 422 μg/m^3), and lower in summer(7 μg/m^3 in June). From May to August, the typical summer period, least severe pollution events were observed, with high precipitation levels accelerating the process of wet deposition to remove PM_(2.5). The case of February presented the most serious pollution, with monthly averaged PM_(2.5)of 181 μg/m^3 and 32% of days with severe pollution. The abundance of PM_(2.5)in winter could be related to increased coal consumption for heating needs. | Yanli Wang Wen Yang Bin Han Wenjie Zhang Mindong Chen Zhipeng Bai | 2016 | Journal of Environmental Sciences2016，28，2： | 5 |
| 9 | Inhibition of platelet aggregation by polyaspartoyl L-arginine and its mechanism显示文摘AIM: To observe the oral anti-platelet efficacy and the potential action mechanism of polyaspartoyl L-arginine (PDR), a new L-arginine rich compound. METHODS: Platelet aggregation was conducted by Born’s method; bleeding time was determined using tail’s bleeding time in mice; platelet adhesion was carried out with glass bottle method; nitric oxide (NO) was tested with Griess’ method; and cAMP, thromboxane B2 (TXB2) and 6-keto-PGF1α were assessed with commercial kits. RESULTS: The inhibition by PDR (15-60 mg/kg ig or 10 mg/kg iv) of platelet aggregation induced by adenosine diphosphate (ADP), collagen or thrombin at 1 h after oral administration or at 20 min after iv injection for rats (P<0.01), and its (15 mg/kg, ig) inhibition of ADP-induced platelet aggregation for rabbits during 6 h after administration were observed. PDR (15-60 mg/kg) prolonged the bleeding time of mice (P<0.05) and (30 mg/kg) increased NO concentration in plasma. On the other hand PDR did not change the contents of cAMP in platelet and TXB2 or 6-keto-PGF1α in plasma. CONCLUSION: PDR is a novel, oral effective platelet aggregation inhibitor and its action mechanism possibly related to increasing NO generation. | Yin-yeWANG Zhi-yuTANG MinDONG Xiao-yanLIU Shi-qiPENG | 2004 | Acta Pharmacologica Sinica2004，25，4： | 2 |
| 10 | Hydrocarbon origin and reservoir forming model research of Longwangmiao Formation,Moxi-Gaoshiti area,Sichuan Basin显示文摘This paper focuses on the Longwangmiao gas reservoir in Moxi-Gaoshiti area,Sichuan Basin.Starting from the tectonic evolution perspective,though comparing biological marker compound and analyzing fluid inclusions,the oil&gas origin and accumulation evolution of Longwangmiao Formation are systematic studied with reference to the burial-thermal evolution of single well geological history in the study area.It is suggested that the oil&gas reservoir is generally characterized by early accumulation,multi-stage filling,late cracking and later adjustment.The oil and gas were mainly sourced from lower Cambrian Qiongzhusi Formation,partly from the Permian source rock.During the geological period,3 major oil&gas fillings occurred in the Longwangmiao Formation,namely Caledonian-Hercynian filling that was small in scale and produced the first phase of paleo-oil reservoir that soon destroyed by Caledonian movement uplift,large-scale Permian filling that gave rise to the second-phase of paleo-oil reservoir and the Triassic-Jurassic filling that enriched the second phase of paleo-oil reservoir.Finally,the paleo-oil reservoir experienced an in-situ cracking during the cretaceous period that gave rise to a natural gas reservoir and left behind carbonaceous bitumen and oily bitumen in the holes of the Longwangmiao Formation. | Mindong Jin Jian Cao Chuanhua Shi Wei Zeng Cheng Shen Kailan Shi Xueying Cheng Xiucheng Tan | 2016 | Petroleum2016，2，2： | 2 |
| 11 | Chrysanthemum indicum ethanol extract attenuates hepatic stellate cell activation in vitro and thioacetamide-induced hepatofibrosis in rats显示文摘Objective:To investigate the antifibrotic effects of Chrysanthemum indicum ethanol extract(CIEE)against activated hepatic stellate cells(HSC)and thioacetamide(TAA)-induced hepatofibrosis in rats.Methods:Cell viability and proliferation of HSC-T6 cells were measured using MTT assay.Primary HSCs were used to study morphology.TAA(200 mg/kg)was used to induced hepatic fibrosis in rats.CIEE(100 and 500 mg/kg)and silymarin(50 mg/kg)were administered orally.Liver functions including alanine transaminase,aspartate transaminase,glutathione,and hydroxyproline levels were measured using commercial kits.Liver sections and fibrotic biomarker expression were measured using hematoxylin and eosin staining and real-time polymerase chain reaction.Results:In vitro study revealed that CIEE(0.1,0.25,and 0.5 mg/mL)inhibited the proliferation of activated HSCs exposed to transforming growth factor(TGF)-β and restored the activated primary HSC morphology.In in vivo studies,TAA-induced increase in liver/body weight ratio(5.46±0.26)was significantly reduced(4.13±0.22)by CIEE(P<0.05 at 500 mg/kg).CIEE(100 and 500 mg/kg)improved the liver functions by significantly attenuating changes in alanine transaminase,aspartate transaminase,glutathione,and hydroxyproline levels(P<0.05).Further,CIEE(100 and 500 mg/kg)ameliorated the histological changes in liver tissue and TGF-β expression significantly(P<0.05)in TAA-induced rats.Conclusions:CIEE significantly protects against TAA-induced liver damage in rats and can be used in the treatment of liver fibrosis. | Yun-Jin Chae Sushruta Koppula Myong-Ki Kim Tony Yoon MinDong Song | 2021 | Asian Pacific Journal of Tropical Biomedicine2021，11，11： | 2 |

| 19 | Improved Visible Transparency of SiO_2/ZnO:Al/CeO_2-TiO_2/SiO_2 Multilayer Films with High UV Absorption and Infrared Reflection Rate显示文摘New visible transparent, UV absorption, and high infrared reflection properties have been realized by depositing multilayer Si O2/Zn O: Al/Ce O2-Ti O2/Si O2 films onto glass substrates at low temperature by radio frequency magnetron sputtering. Optimum thickness of Si O2, Zn O: Al(ZAO) and Ce O2-Ti O2(CTO) films were designed with the aid of thin film design software. The degree of antireflection can be controlled by adjusting the thickness and refractive index. The outer Si O2 film can diminish the interference coloring and increase the transparency; the inner Si O2 film improves the adhesion of the coating on the glass substrate and prevents Ca2+, Na+ in the glass substrate from entering the ZAO film. The average transmittance in the visible light range increases by nearly 18%-20%, as compared to double layer ZAO/CTO films. And the films display high infrared reflection rate of above 75% in the wavelength range of 10-25 μm and good UV absorption(> 98%) properties. These systems are easy to produce on a large scale at low cost and exhibit high mechanical and chemical durability. The triple functional films with high UV absorption, antireflective and high infrared reflection rate will adapt to application in flat panel display and architectural coating glass, automotive glass, with diminishing light pollution as well as decreasing eye fatigue and increasing comfort. | 倪佳苗 赵修建 ZHAO Qingnan ZHENG Mindong | 2015 | Journal of Wuhan University of Technology(Materials Science)2015，30，5： | 1 |
