2Trace Elements Characteristics of Black Shales from the Ediacaran Doushantuo Formation, Hubei Province, South China: Implications for Redox and Open vs. Restricted Basin Conditions显示文摘In the present study, we carried out trace element analyses of black shales of the Ediacaran Doushantou Formation from two sections(Jiulongwan, Baiguoyuan) in Hubei Province, South China. Mo-U characteristics of black shales from the two sections and compiled Mo-U data of Doushantuo black shales from sections of a variety of sedimentary facies described the temporal/spatial variability in the redox conditions of paleo-seawater during deposition of the Doushantuo Formation. Changes in Mo-U patterns of the Doushantuo Member Ⅱ(DST2) shales of open marine environments are consistent with a shift from a predominately oxic to a predominately anoxic ocean during their deposition. Mo-U patterns of the DST2 black shales from intra-shelf sections reflect basin restriction may have happened in the intra-shelf basin and are compatible with the redox-stratified model of the intra-shelf basin. Mo-U patterns of black shales of the Doushantuo Member IV(DST4) reveal that the shales from intra-shelf sections have more pronounced Mo enrichment and more significant enrichment of Mo over U than the slope shales, indicating the operation of a Mn particulate shuttle in the intra-shelf basin. High Mo/TOC ratios of the DST4 at the intra-shelf sections, in combination with similar Mo-TOC patterns of the DST4 from both intra-shelf and slope sections, indicate the intrashelf basin was well connected to the open ocean during deposition of the DST4.Bi Zhu Shaoyong Jiang Daohui Pi Lu Ge Jinghong Yang 2018Journal of Earth Science2018,29,2:11
3Density-based trajectory outlier detection algorithm显示文摘With the development of global position system(GPS),wireless technology and location aware services,it is possible to collect a large quantity of trajectory data.In the field of data mining for moving objects,the problem of anomaly detection is a hot topic.Based on the development of anomalous trajectory detection of moving objects,this paper introduces the classical trajectory outlier detection(TRAOD) algorithm,and then proposes a density-based trajectory outlier detection(DBTOD) algorithm,which compensates the disadvantages of the TRAOD algorithm that it is unable to detect anomalous defects when the trajectory is local and dense.The results of employing the proposed algorithm to Elk1993 and Deer1995 datasets are also presented,which show the effectiveness of the algorithm.Zhipeng Liu Dechang Pi Jinfeng Jiang 2013Journal of Systems Engineering and Electronics2013,24,2:9
4Rare Earth Element Geochemistry of Phosphatic Rocks in Neoproterozoic Ediacaran Doushantuo Formation in Hushan Section from the Yangtze Gorges Area, South China显示文摘Phosphatic rocks are widely distributed in Neoproterozoic Ediacaran Doushantuo Formation in Yangtze Gorges Area, South China. In this study, rare earth element geochemistry of eight phosphatic rock samples from the Hushan Section has been studied. All the samples display typical hat-shaped REE patterns, moderate negative Ce anomalies(Ce/Ce*=0.55 to 0.67), slightly positive Eu anomalies(Eu/Eu*=1.05 to 1.22) and low Y/Ho ratios(38.2±5.6). The hat-shaped REE patterns indicate diagenetic alteration of the primary REE signatures, which coincides with detrital siliciclastic sources of REE based on the Y/Ho ratios. The degree of Negative Ce anomalies and positive Eu anomalies may have recorded the redox features of diagenetic fluids, suggesting an anoxic environment during the phosphogenesis processes in Neoproterozoic Ediacaran Doushantuo Formation, South China. The geochemical comparison between the Lower Phosphorite Layer and Upper Phosphorite Layer at Hushan indicates a greater degree of diagenesis occurred in the Upper Layer than the Lower one. Besides the terrigenous sources of REE, organic materials could have also played a role on the REE characteristics.Hong Xin Shaoyong Jiang Jinghong Yang Heping Wu Daohui Pi 2016Journal of Earth Science2016,27,2:7
5Influence of surface modification of SrFe12O19 particles with oleic acid on magnetic microsphere preparation显示文摘Oleic acid was used as surface modification agent to improve the hydrophobicity of magnetic strontium hexaferrite particles.The structure and properties of treated magnetic particles were characterized by scanning electronic microscopy(SEM),Fourier transform infrared spectra(FTIR),powder X-ray diffraction(XRD) and magnetic property measurement system(MPMS).The results show that oleic acid is chemically enwrapped on the surface of SrFe12O19 particles.Magnetic particles modified by oleic acid are highly dispersible and strongly responsive to magnetism but with slight decrease in saturated magnetization.The affinity between magnetic particles and monomers is improved by surface modification,resulting in increased particle incorporation in magnetic polymeric microspheres.The surface modification mechanism of magnetic particles by oleic acid is addressed in this work.Sifang Kong Peipei Zhang Xiufang Wen Pihui Pi Jiang Cheng Zhuoru Yang Jing Hai 2008Particuology2008,6,3:7
6Studies of the intestinal absorption of the alkaloids in the Wu-tou decoction combined with different incompatible medicinal herbs in a Caco-2 cell culture system using UPLC-MS/MS显示文摘In this study,seven alkaloids were detected in Wu-tou decoction using ultra performance liquid chromatography coupled with tandem mass spectrometry(UPLC-MS').The aim of this study was to investigate the effect of Fritillariae Cirrhosae Bulbus,Fritillariae Thunbergii Bulbils,Pinelliae Rhizoma in different ratios with Wu-tou decoction(2:1,1:1,1:2) by measuring the therapeutic effects in Wu-tou decoction of main seven alkaloids including benzoylaconitine(BA),benzoylmesaconitine(BM),benzoylhypaconitine(BH),hypaconitine(HA),fuziline(FU),niaolin(NE) and deoxyaconitine(DA).The permeability of aconitum alkaloids extract through a Caco-2 cell monolayer was analyzed in the absence and presence of Fritillariae Cirrhosae Bulbus,Fritillariae Thunbergii Bulbus,and Pinelliae Rhizoma,respectively.The results showed that Pinelliae Rhizoma could reduce the absorption of the alkaloids and increase the excretion of the alkaloids,which would attenuate the therapeutic effects of Wu-tou decoction.Therefore.Pinelliae Rhizoma is an incompatible herb of Wu-tou decoction because of the inhibition of the absorption of alkaloids in the intestine.And that Fritillariae Cirrhosae Bulbus and Fritillariae Thunbergii Bulbus showed the effects to improve the permeability of the alkaloids in Wu-tou decoction.These effects of these two herbs were similar,but the former was stronger than the latter,which most likely is clue to the fact that the compositions of these two traditional Chinese medicines are similar.The in vitro data suggests that the compounds such as fritillary presented in alkaloids in the formula maybe improve the therapeutic function caused by the increased bioavailability of alkaloids in intestine.Hong Kan Wen-Yue Jiang Ru Ding Zhong-Ying Liu Zi-Feng Pi Zhi-Qiang Liu 2015Chinese Chemical Letters2015,26,5:5
7Improved performance of aluminum pigments encapsulated in hybrid inorganic-organic films显示文摘An organic silane acrylate resin(PMBK) was synthesized by free-radical solution polymerization using methyl methacrylate,butyl acrylate and(3-methacryloxypropyl)trimethoxysilane as monomers.Aluminum(Al) particles were then encapsulated in inorganic-organic hybrid films that were prepared by hydrolysis and condensation of PMBK and tetraethyl orthosilicate(TEOS) on the surface of Al pigments.Characterization results showed that PMBK and TEOS could simultaneously hydrolyze and condense with hydroxyl groups on the surface of the Al particles to form composite Al particles coated with inorganic-organic hybrid films.Compared with raw Al particles,the corrosion resistance and adhesive properties of paint films containing the composite Al particles were improved greatly,while the glossiness of the paint films decreased slightly,from 48.6° to 47.0°.In alkaline media(pH 11),the volume of evolved H_2 of composite Al particles was only 3.5 mL,whereas that of raw Al was 83.5 mL.The glossiness of paint films containing composite Al particles decreased by 1.66%after immersion in alkaline media for24 h,whereas that of raw Al decreased by 14.82%.Peel-off tests of the paint films showed that the composite particles moved slightly away from the paint films.In contrast,the raw Al particles were seriously desquamated,suggesting encapsulation of hybrid films can greatly improve the adhesive properties of Al particles in paint films.Pihui Pi Chao Liu Xiufang Wen Lianfu Zheng Shouping Xu Jiang Cheng 2015Particuology2015,13,2:5

9Modeling uniaxial tensile deformation of polycrystalline Al using CPFEM显示文摘The crystal plasticity finite element modeling(CPFEM)is realized in commercial finite element code ABAQUS with UMAT subroutine on the basis of the crystal plasticity theory of rate dependent polycrystal constitutive relations in the mesoscopic scale.The initial orientations obtained by electron backscatter diffraction(EBSD)are directly input into the CPFEM to simulate the mechanical response of polycrystaUine 1050 pure Al in uniaxial tensile deformation.Two polycrystal models and two tensile strain rates were used in the simulations.The stress-strain curves of tensile deformation were analyzed.The predictions and the corre- sponding experiment result show reasonable agreement and slight deviation with experiments.The flow true stress of strain rate 0.01 s^(-1)is higher than that of strain rate 0.001 s^(-1).At the strain less than 0.05,the stress saturated rate of the experiment is higher than the simulated results.However,the stress saturated rate of the experiment becomes gentler than the corresponding simulated predictions at the strain over 0.05.Also,necking was simulated by the two models,but the necking strain is not well predicted.Tensile textures at strain 0.25 were predicted at the low strain rate of 0.001 s^(-1).The predictions are in good accord with the experimental results.Huachun pi Jingtao Han Chuanguo Zhang A.

10Preparation and characterization of porous titania-grafted poly(styrene-divinylbenzene)/maleic anhydride nanocomposite microspheres显示文摘Mesoporous titania-grafted poly(styrene-divinylbenzene)/maleic anhydride [P(St-DVB)/MA] nanocomposite microspheres were prepared by an open ring reaction method.The titania nanoparticles were first modified by attachment of amino groups to their surface to prevent particle aggregation,and to allow the nanoparticles to covalently bond the polymer microspheres,the surface of which was modified by attachment of MA functional groups to enable the polymer to retain their porous structures and to react with the amino groups on the surface of the titania particles.The porous nanocomposite microspheres were detected by FTIR,SEM,TEM,XRD and UV-Vis spectrophotometry.The results indicated that the nanocomposite microspheres were composed of nanosized titania uniformly distributed on the surface,and exhibited better UV absorbing property than pure polymer microspheres or unmodified titania.Furthermore,compared with pure porous polymer microspheres,the nanocomposite microspheres showed more efficient UV protection and slow release of Parsol-1789(a photo-reactive and cosmetic agent) held inside the porous network of the microspheres.Li Sen Wang Kuan Zhang ZhiRen Song ChunLian Cheng Jiang Yang ZhuoRu Wen XiuFang Pi PiHui 2010Science China Chemistry2010,53,3:3

12NUPR1 promotes the proliferation and metastasis of oral squamous cell carcinoma cells by activating TFE3-dependent autophagy显示文摘Oral squamous cell carcinoma(OSCC)is the most common type of oral malignancy,and metastasis accounts for the poor prognosis of OSCC.Autophagy is considered to facilitate OSCC development by mitigating various cellular stresses;nevertheless,the mechanisms of autophagy in OSCC cell proliferation and metastasis remain unknown.In our study,high-sensitivity label-free quantitative proteomics analysis revealed nuclear protein 1(NUPR1)as the most significantly upregulated protein in formalin-fixed paraffin-embedded tumour samples derived from OSCC patients with or without lymphatic metastasis.Tengfei Fan Xiaoning Wang Sheng Zhang Ping Deng Yi Jiang Yidan Liang Sheng Jie Qing Wang Chuwen Li Guocai Tian Zhen Zhang Zhenhu Ren Bo Li Yanrong Chen Zhijing He Yan Luo Mingliang Chen Hanjiang Wu Zhengping Yu Huifeng Pi Zhou Zhou Zhiyuan Zhang 2022Signal Transduction and Targeted Therapy2022,7,5:2

15Morphologies and Superhydrophobicity of Hybrid Film Surfaces Based on Silica and Fluoropolymer显示文摘Fluoropolymer and different kinds of silica particles were used for controlling surface chemistry and morphology, respectively.A superhydrophobic surface originated from strawberry-like or quincunx-shaped composite silica particles was obtained.The dual size particles are obtained by utilizing the graft of different modified silica particles with epoxy functional group and amine functional group.This makes the surface of film form a composite interface to have irregular binary structure which plays an essential role in trapping air between the substrate surface and the liquid droplets to be necessary for high contact angle and low contact angle hysteresis.The maximum contact angle for water on the hybrid film is about 174±2°and the contact angle hysteresis is less than 2°.The surface morphologies,roughness and the wettability on the surface of films containing different structural silica particles were compared.It was shown that the hierarchical irregularly structure with a low roughness factor and high air-trapped ratio is indispensable for superhydrophobic surface. Although this structural surfaces based on composite silica particles play a vital role in governing the surface wettability,it is necessary to combine with a low surface energy to make the surface superhydrophobic.Ailan QU Xiufang WEN Pihui PI Jiang CHENG Zhuoru YANG 2008Journal of Materials Science & Technology2008,24,5:2
