| 1 | Simulated-sunlight-activated photocatalysis of Methylene Blue using cerium-doped SiO_2/TiO_2 nanostructured fibers显示文摘Cerium-doped SiO 2 /TiO 2 nanostructured fibers were fabricated by electrospinning technology.The prepared fibers were characterized by thermogravimetric analysis(TGA),scanning electron microscopy(SEM),X-ray diffraction(XRD) and Fourier transform infrared spectroscopy(FT-IR).Using the fibers as catalysts,photocatalytic degradation of Methylene Blue(MB) aqueous solution was carried out under simulated sunlight.The 0.2% Ce doping proved to be the optimal concentration for the doping of TiO 2 /SiO 2,compared to other Ce-doped molar concentrations.The 0.2% Ce-doped SiO 2 /TiO 2 fibers exhibited higher photocatalytic activity than industrial Degussa P25 and the samples doped with only Ce or SiO 2.The reasons for improving the photocatalytic activity were also discussed.Several operational parameters were studied,which showed that the photocatalytic efficiency of MB was influenced by parameters such as the initial dye concentration,the initial pH,inorganic anions,and so on.In addition,the influences of an electron acceptor and a radical scavenger suggested that OH was the dominant photooxidant during the photocatalytic process.The reuse evaluation of the fibers indicated that their photocatalytic activity had good stability. | Yu Liu Hongbing Yu Zhenning Lv Sihui Zhan Jiangyao Yang Xinhong Peng Yixuan Ren Xiaoyan Wu | 2012 | Journal of Environmental Sciences2012，24，10： | 10 |

| 8 | Underestimated contribution of fugitive emission to VOCs in pharmaceutical industry based on pollution characteristics, odorous activity and health risk assessment显示文摘Fugitive emission has been becoming an important source of volatile organic compounds(VOCs) in pharmaceutical industry,but the exact contribution of fugitive emission remains incompletely understood.In present study,pollution characteristics,odorous activity and health risk of stack and fugitive emissions of VOCs from four functional units (e.g.,workshop,sewage treatment station,raw material storage and hazardous waste storage) of three representative pharmaceutical factories were investigated.Workshop was the dominant contributor to VOCs of fugitive emission in comparison with other functional units.Extreme high concentration of VOCs from fugitive emission in unsealed workshop (94.87 mg/m^(3))was observed relative to sealed one (1.18 mg/m^(3)),accounting for 31%and 5%of total VOCs,respectively.Fugitive emission of VOCs in the unsealed workshop mainly consisted of nhexane,1-hexene and dichloromethane.Odorous activity indexes and non-cancer hazard ratios of these VOCs from fugitive emission in the unsealed workshop were as high as that from stack exhaust.Furthermore,cancer risk of dichloromethane from fugitive emission and stack exhaust was up to (1.6-1.8)×10^(-5).Odorous activity or health risk index of the VOCs from fugitive emission was up to 13 or 11 times of the corresponding threshold value,posing remarkable health threat on pharmaceutical workers.Our?ndings highlighted the possibly underestimated contribution of fugitive emission on VOCs in the pharmaceutical industry. | Qinhao Lin Zhong Gao Weikun Zhu Jiangyao Chen Taicheng An | 2023 | Journal of Environmental Sciences2023，，4： | 1 |
| 9 | Synthetic and immunological studies on the OCT4 immunodominant motif antigen-based anti-cancer vaccine显示文摘Objective:Cancer stem cell is one of the important causes of tumorigenesis as well as a drug target in the treatment of malignant tumor.However,at present,there is no immune vaccine targeting these cells.Octamer-binding transcription factor 4(OCT4),a marker of embryonic stem cells and germ cells,often highly expresses in the early stages of tumorigenesis and is therefore a good candidate for cancer vaccine development.Methods:To identify the optimal carrier and adjuvant combination,we chemically synthesized and linked three different OCT4 epitope antigens to a carrier protein,keyhole limpet hemocyanin(KLH),combined with Toll-like receptor 9 agonist(TLR9).Results:Immunization with OCT4-3+TLR9 produced the strongest immune response in mice.In prevention assays,significant tumor growth inhibition was achieved in BABL/c mice treated with OCT4-3+TLR9(P<0.01).Importantly,the results showed that cytotoxic T lymphocyte activity and the inhibition of tumor growth were enhanced in mice immunized with OCT4-3 combined with TLR9.Meanwhile,multiple cytokines[such as interferon(IFN)-γ(P<0.05),interleukin(IL)-12(P<0.05),IL-2(P<0.01),and IL-6(P<0.05)]promoting cellular immune responses were shown to be greatly enhanced in mice immunized with OCT4-3+TLR9.Moreover,we considered safety considerations in terms of the composition of the vaccines to help facilitate the development of effective next-generation vaccines.Conclusions:Collectively,these experiments demonstrated that combination therapy with TLR9 agonist induced a tumor-specific adaptive immune response,leading to the suppression of primary tumor growth in testis embryonic carcinoma. | Tingting Chen Kan Liu Jiangyao Xu Tianying Zhan Maixian Liu Li Li Zhiwen Yang Shuping Yuan Wenyi Zou Guimiao Lin Dennis ACarson Christina CNWu Xiaomei Wang | 2020 | Cancer Biology & Medicine2020，17，1： | 0 |
| 10 | Analyses on the Overall Codon Usage Pattern in Fish Rhabdovirus显示文摘The codon usage bias and the base compositions in the available 49 complete fish rhabdovirus genome sequences were investigated. The high correlation between GC12% and GC3% suggested that mutational pressure rather than natural selection was the main factor determining the codon usage and base component in fish rhabdovirus,most of the spots lying below the expected curve( ENC vs GC3%) also suggested that codon usage bias in these 49 genomes was influenced by mutational pressure in codon usage pattern. Through PCA analysis based on RSCU,all ORFs in the 49 fish rhabdoviurs genomes were clustered into two parts,and this result showed that hosts played a role in codon usage pattern of fish rhabdovirus genomes. Further,comparison between SVCV,INHV,VHSV and their hosts suggested the effect of natural host on the codon usage pattern took part in the evolution process of fish rhabdovirus. This study represents the most comprehensive analysis to date for fish rhabdovirus codon usage patterns. | Yanping MA Hao KE Jiangyao MA Zhiling LIANG Le HAO Zhenxing LIU | 2018 | Agricultural Biotechnology2018，7，1： | 0 |
| 11 | Photodegradation of xylene isomers:Kinetics,mechanism,secondary pollutant formation potential and health risk evaluation显示文摘Photodegradation technology has been widely applied in the purification of industrial aromatic hydrocarbons.However,whether this technology efficiently removes the pollutants to prevent secondary pollution and health risk is still unclear.Here,the photodegradation processes of three xylenes were compared under designed reaction atmospheres and light sources.Xe lamp showed poor photodegradation ability toward xylenes,no matter in N_(2) or N_(2)+O_(2)system,while much higher photodegradation performance of xylenes were obtained under ultraviolet(UV)and vacuum ultraviolet(VUV)irradiation,especially in N_(2)+O_(2)+VUV system,where 97.9%of m-xylene,99.0%of o-xylene or 87.5%of p-xylene with the initial concentration of 860 mg/m^(3) was removed within 240 min.The xylenes underwent three processes of photo-isomerization,photodecomposition and photo-oxidation to produce intermediates of aromatics,alkanes and carbonyls.Among them,the photo-isomerization products showed the highest concentration percentage(e.g.,≥50%in o-xylene system),confirming that photo-isomerization reaction was the dominated photodegradation process of xylenes.Moreover,these isomerized products not only contributed about 97%and91%to the formation potential of O3(OFP)and secondary organic aerosols(SOAFP),but also displayed obvious non-carcinogenic risk,although one of photodecomposition product—benzene showed the highest occupational exposure risk.Therefore,the secondary pollution and health risks of photodegradation products of xylenes were non-ignorable,although the OFP,SOAFP and health risks of the generated products reduced at least 4.5 times in comparison with that of the degraded xylenes.The findings are helpful for the appropriate application of this technology in the purification of industrial organic waste gas. | Xiaoyan Chen Weikun Zhu Sufen Feng Jiangyao Chen | 2024 | Journal of Environmental Sciences2024，，2： | 0 |
| 12 | Reactor characterization and primary application of a state of art dual-reactor chamber in the investigation of atmospheric photochemical processes显示文摘Increasing attention has been paid to the air pollution more recently. Smog chamber has been proved as a necessary and effective tool to study atmospheric processes, including photochemical smog and haze formation. A novel smog chamber was designed to study the atmospheric photochemical reaction mechanism of typical volatile organic compounds(VOCs) as well as the aging of aerosols. The smog chamber system includes an enclosure equipped with black lights as the light source, two parallel reactors(2 m^3 of each) with separate control of light source and temperature, with a series of coupled instruments for online monitoring of gas phase and particle phase reactants and products. Chamber characterization, including air source stability, effective light intensity, temperature stability, as well as gas phase and particle phase wall losses, were carried out before further research. The results showed that our smog chamber systems developed by other domestic and international groups. It was also observed that the wall loss of aromatic VOCs varied with different functional groups as well as the isomerism. The results of preliminary simulation experiment from styrene-NO_x demonstrated that the chamber can be well utilized to simulate gas-particle conversion progresses in the atmosphere. | Hao Luo Guiying Li Jiangyao Chen Yujie Wang Taicheng An | 2020 | Journal of Environmental Sciences2020，32，12： | 0 |

| 14 | Assessing the role of mineral particles in the atmospheric photooxidation of typical carbonyl compound显示文摘Mineral particles are ubiquitous in the atmosphere and exhibit an important effect on the photooxidation of volatile organic compounds(VOCs).However,the role of mineral particles in the photochemical oxidation mechanism of VOCs remains unclear.Hence,the photooxi-dation reactions of acrolein(ARL)with OH radical(OH)in the presence and absence of SiO_(2) were investigated by theoretical approach.The gas-phase reaction without SiO_(2) has two distinct pathways(H-abstraction and OH-addition pathways),and carbonyl-H-abstraction is the dominant pathway.In the presence of SiO_(2),the reaction mechanism is changed,i.e.,the dominant pathway from carbonyl-H-abstraction to OH-addition to carbonyl C-atom.The energy barrier of OH-addition to carbonyl C-atom deceases 21.33 kcal/mol when SiO_(2) is added.Carbonyl H-atom of ARL is occupied by SiO_(2) via hydrogen bond,and carbonyl C-atom is ac-tivated by SiO_(2).Hence,the main product changes from H-abstraction product to OH-adduct in the presence of SiO_(2).The OH-adduct exhibits a thermodynamic feasibility to yield HO_(2) radical and carboxylic acid via the subsequent reactions with O_(2),with implications for O 3 formation and surface acidity of mineral particles. | Yongpeng Ji Xingyu Chen Yuqi Xiao Yuemeng Ji Weina Zhang Jiaxin Wang Jiangyao Chen Guiying Li Taicheng An | 2021 | Journal of Environmental Sciences2021，33，7： | 0 |
