| 1 | Experimental research on hydrophilic characteristics of natural soft rock at high stress state显示文摘In order to study features of rock–water interaction, a self-developed experimental system called Intelligent Testing System for Water Absorption in Deep Soft Rocks(ITSWADSR) was utilized to analyze the hydrophilic behaviors of natural soft rock at high stress state. Combining X-ray diffraction and mercury injection test, main influencing factors on hydrophilic characteristics were studied. According to the results, it could be concluded as the following:(1) the effective porosity, and the content of illite, illite/smectite formation(S = 5%) and kaolinite have positive correlation with the water absorption capacity of rock; meanwhile, the initial moisture content, fractal dimension of effective pores, illite/smectite formation(S = 30%) and chlorite present negative correlation;(2) among the positive factors, the ascending order is kaolinite, illite/smectite formation(S = 5%) and illite;(3) the descending order among the negative factors are chlorite, illite/smectite formation(S = 30%) and fractal dimension of the effective pores;(4) influence of effective porosity on the pressurized water absorbing capacity of rock is minimal, while it is maximal in the process of no pressurized water absorption. | Guo Hongyun Lei Xiangyang Zhang Yumei Yang Guoxing Niu Zhang | 2015 | International Journal of Mining Science and Technology2015，25，3： | 10 |
| 2 | Preliminary investigation on cytotoxicity of fluorinated polymer nanoparticles显示文摘As well-known persistent organic pollutants(POPs), organofluorine pollutants such as perfluorooctane sulfonate(PFOS) have been proven to be bioaccumulated and harmful to health. However, toxicological assessment of organofluorinated nanoparticles, which have emerged as a novel tool for biomedical and industrial applications, is lacking, to the best of our knowledge. To assess the biological effects and health risk of fluorinated nanoparticles,trifluoroethyl aryl ether-based fluorinated poly(methyl methacrylate) nanoparticles(PTFEPMMA NPs) were synthesized with various fluorine contents(PTFE-PMMA-1 NPs 12.0 wt.%,PTFE-PMMA-2 NPs 6.1 wt.% and PTFE-PMMA-3 NPs 5.0 wt.%), and their cytotoxicity was investigated in this study. The in vitro experimental results indicated that the cytotoxicity of PTFE-PMMA NPs was mild, and was closely related to their fluorine(F) contents and Fcontaining side chains. Specifically, the cytotoxicity of PTFE-PMMA NPs decreased with increasing F content and F-containing side chains. After exposure to PTFE-PMMA NPs at a sublethal dose(50 μg/m L) for 24 hr, the phospholipid bilayer was damaged, accompanied by increasing permeability of the cell membrane. Meanwhile, the intracellular accumulation of reactive oxygen species(ROS) occurred, resulting in the increase of DNA damage, cell cycle arrest and cell death. Overall, the PTFE-PMMA NPs were found to be relatively safe compared with typical engineered nanomaterials(ENMs), such as silver nanoparticles and graphene oxide, for biomedical and industrial applications. | Xue Wang Wenge Cheng Qiuyuan Yang Hongyun Niu Qian Liu Yun Liu Ming Gao Ming Xu An Xu Sijin Liu Xiaoyu Huang Yuguo Du | 2018 | Journal of Environmental Sciences2018，30，7： | 2 |
| 3 | One-pot molten salt method for constructing CdS/C_(3)N_(4) nanojunctions with highly enhanced photocatalytic performance for hydrogen evolution reaction显示文摘The construction of heterojunction photocatalysts for efficiently utilizing solar energy has attracted considerable attention to solve the energy crisis and reduce environmental pollution.In this study,we use the energy released from an easily-occurred exothermic chemical reaction to serve as the drive force to trigger the formation of Cd S and C_(3)N_(4) nanocomposites which are successfully fabricated with cadmium nitrate and thiourea without addition of any solvents and protection of inert gas at initial temperature,a little higher than the melting point of thiourea.The as-prepared Cd S/C_(3)N_(4) materials exhibit high efficiency for photocatalytic hydrogen evolution reaction(HER)with the HER rate as high as 15,866μmol/(g·hr)under visible light irradiation(λ>420 nm),which is 89 and 9 times those of pristine C_(3)N_(4) and Cd S,respectively.Also,the apparent quantum efficiency(AQE)of Cd S/C_(3)N_(4)–1:2–200–2(Cd S/C_(3)N_(4)–1:2–200–2 means the ratio of Cd to S is 1:2 and the reaction temperature is set at 200℃ for two hours)reaches 3.25%atλ=420±15 nm.After irradiated for more than 24 hr,the HER efficiencies of Cd S/C_(3)N_(4) do not exhibit any attenuation.The DFT calculation suggests that the charge difference causes an internal electric field from C_(3)N_(4) pointing to Cd S,which can more effectively promote the transfer of photogenerated electrons from Cd S to C_(3)N_(4).Therefore,most HER should occur on C_(3)N_(4) surface where photogenerated electrons accumulate,which largely protects Cd S from photo-corrosion. | Weijia Zhao Hongyun Niu Yongliang Yang Hongzhou Lv Jungang Lv Yaqi Cai | 2022 | Journal of Environmental Sciences2022，34，2： | 2 |

| 14 | The MIEL1-ABI5/MYB30 regulatory module fine tunes abscisic acid signaling during seed germination显示文摘The transcription factor ABSCISIC ACID INSENSITIVE5(ABI5)plays a crucial role in abscisic acid(ABA)signaling during seed germination.However,how ABI5 is regulated during this process is poorly understood.Here,we report that the ubiquitin E3 ligase MIEL1 and its target transcription factor MYB30 modulate ABA responses in Arabidopsis thaliana during seed germination and seedling establishment via the precise regulation of ABI5.MIEL1 interacts with and ubiquitinates ABI5 to facilitate its degradation during germination.The transcription factor MYB30,whose turnover is mediated by MIEL1 during seed germination,also interacts with ABI5 to interfere with its transcriptional activity.MYB30 functions downstream of MIEL1 in the ABA response,and both are epistatic to ABI5 in ABA-mediated inhibition of seed germination and postgerminative growth.ABA treatment induces the degradation of MIEL1 and represses the interaction between MIEL1 and ABI5/MYB30,thus releasing both ABI5 and MYB30.Our results demonstrate that MIEL1 directly mediates the proteasomal degradation of ABI5 and inhibits its activity via the release of its target protein MYB30,thus ensuring precise ABA signaling during seed germination and seedling establishment. | Kaili Nie Hongyun Zhao Xiaopei Wang Yanli Niu Huapeng Zhou Yuan Zheng | 2022 | Journal of Integrative Plant Biology2022，64，4： | 1 |

| 19 | Advanced molecular-fingerprinting analysis of dissolved organic sulfur by electrospray ionization-Fourier transform ion cyclotron resonance mass spectrometry using optimal spray solvent显示文摘Molecular level characterization of dissolved organic sulfur(DOS)by electrospray ionizationFourier transform ion cyclotron resonance mass spectrometry(ESI-FTICR MS)is necessary for further understanding of the role of DOS in the environment.Here,ESI spray solvent,a key parameter for ion production during ESI process,was investigated for its effect on the molecular characterization of DOS by ESI-FTICR MS.100%MeOH as spray solvent was found for the first time to remarkably enhance the ionization efficiency of the majority of CHOS-molecules in NOM,which facilitated a total of 1473 CHOS-molecular formulas with one sulfur atom to be detected.The number of CHOS-molecular formulas obtained using 100%MeOH as spray solvent increased notably over 740 in comparison with those using 50%MeOH aqueous solution(731)or 50%ACN aqueous solution(653).Moreover,due to the enhancement of ionization efficiency of DOS during ESI processes,the tandem mass spectra of the NOM CHOS-molecules could be easily obtained using 100%MeOH as spray solvent,which were hardly obtained using 50%MeOH aqueous solution as spray solvent.The results of the tandem mass spectra suggested the first discovery of organosulfates or sulfonic acids in Suwannee River NOM sample.A simple method based on 100%MeOH as ESI spray solvent for advanced molecular characterization of DOS by ESI-FTICR MS was proposed and applied,and the results revealed more molecular information of DOS in sea DOM samples. | Dong Cao Ziyu Rao Fanglan Geng Hongyun Niu Yali Shi Yaqi Cai Yuehui Kang | 2020 | Journal of Environmental Sciences2020，32，11： | 0 |
