4Characteristics of sewage sludge and distribution of heavy metal in plants with amendment of sewage sludge显示文摘In order to better understand land application of sewage sludge, the characterization of heavy metals and organic pollutants were investigated in three different sewage sludges in Shanghai City, China. It was found that the total concentrations of Cd in all of sewage sludge and total concentrations of Zn in Jinshan sewage sludge, as well as those of Zn, Cu, and Ni in Taopu sludge are higher than Chinese regulation limit of pollutants for sludge to be used in agriculture. Leachability of Hg in all of studied samples and that of Cd in Taopu sewage sludge exceed the limit values of waste solid extraction standard in China legislation. Based on the characteristics for three kinds of sewage sludge, a pot experiment was conducted to investigate the effect of soil amended with Quyang sewage sludge on the accumulation of heavy metal by Begonia semperflorens-hybr; Ophiopogon japonicus (L.F.) Ker-Gaw; Loropetalum chindense-var. rubrum; Dendranthema morifolium; Viola tricolor; Antirrhinum majus; Buxus radicans Sieb; Viburnum macrocephalum; Osmanthus fragrans Lour; Cinnamomum camphora siebold and Ligustrum lucidum ait. Results showed that 8 species of plant survived in the amended soil, and moreover they flourished as well as those cultivated in the control soil. The heavy metal concentration in plants varied with species, As, Pb, Cd and Cr concentration being the highest in the four herbaceous species studied, particularly in the roots of D. morifolium. These plants, however, did not show accumulator of As, Pb, Cd and Cr. The highest concentration of Ni and Hg was found in the roots of D. morifolium, followed by the leaves of B. semperflorens-hybr. Levels of Zn and Cu were much higher in D. morifolium than in the other plant species. D. morifolium accumulated Ni, Hg, Cu and Zn, which may contribute to the decrease of heavy metal contents in the amended soil. Treatment with sewage sludge did not significantly affect the uptake of heavy metals by the L. chindense-var. rubrum, however, it significantly affected the uptake of heavy metals by D. morifolium.DAI Jia-yin CHEN Ling ZHAO Jian-fu MA Na 2006Journal of Environmental Sciences2006,18,6:18
5FY-3E:The First Operational Meteorological Satellite Mission in an Early Morning Orbit显示文摘Fengyun-3 E(FY-3E),the world’s first early-morning-orbit meteorological satellite for civil use,was launched successfully at the Jiuquan Satellite Launch Center on 5 July 2021.The FY-3E satellite will fill the vacancy of the global early-morning-orbit satellite observation,working together with the FY-3C and FY-3D satellites to achieve the data coverage of early morning,morning,and afternoon orbits.The combination of these three satellites will provide global data coverage for numerical weather prediction(NWP)at 6-hour intervals,effectively improving the accuracy and time efficiency of global NWP,which is of great significance to perfect the global earth observing system.In this article,the background and meteorological requirements for the early-morning-orbit satellite are reviewed,and the specifications of the FY-3E satellite,as well as the characteristics of the onboard instrumentation for earth observations,are also introduced.In addition,the ground segment and the retrieved geophysical products are also presented.It is believed that the NWP communities will significantly benefit from an optimal temporal distribution of observations provided by the early morning,mid-morning,and afternoon satellite missions.Further benefits are expected in numerous applications such as the monitoring of severe weather/climate events,the development of improved sampling designs of the diurnal cycle for accurate climate data records,more efficient monitoring of air quality by thermal infrared remote sensing,and the quasicontinuous monitoring of the sun for space weather and climate.Peng ZHANG Xiuqing HU Qifeng LU Aijun ZHU Manyun LIN Ling SUN Lin CHEN Na XU 2022Advances in Atmospheric Sciences2022,39,1:13
6Urban expansion in China and its effect on cultivated land before and after initiating'Reform and Open Policy'显示文摘Urbanization in China has expanded at an unprecedented speed since the declaration of 'Reform and Open Policy'and presented many challenges. Unbalanced regional development, appearance of super megacities and concomitant problems,and conflicts between urbanization and cultivated land protection are three critical problems that Chinese urbanization has to face. To develop new plans for foreseeable future urbanization in China, it is critical to understand the evolving history of cities across China. This study maps urban expansion of 60 typical Chinese cities based on large amount of remote sensing data and the labor-intensive image interpretation method, in order to understand the history of urban expansion from the 1970 s to 2013.Results showed that area of cities expanded 5.23 times compared to their area in the 1970 s. Urban expansion in China accelerated three times(1988–1996, 1999–2006, and 2009–2011) and decelerated three times(1997–1998, 2007–2008, and 2012–2013) over the 40 years. The urban area of South China expanded most significantly 9.42 times, while the urban area in Northeast China expanded only 2.37 times. The disparity among different administrative ranks of cities was even greater than(3.81 times) the differences among different regions. Super megacities have been continuously expanding at a fast rate(8.60-fold), and have not shown obvious signs of slowing down. The proportion of cultivated land among the land sources for urban expansion decreased to a small extent in the 1990 s, but cultivated land continues to be the major land source for urban expansion. Effective future urbanization needs controlling the expansion scale of large cities and reasonably developing medium and small cities, as well as balancing regional development.ZHANG ZengXiang WEN QingKe LIU Fang ZHAO XiaoLi LIU Bin XU JinYong YI Ling HU ShunGuang WANG Xiao ZUO LiJun LI Na LI MinMin SHI LiFeng ZENG Tian JU HongRun 2016Science China Earth Sciences2016,59,10:12
7Recent progress in engineering near-infrared persistent luminescence nanoprobes for time-resolved biosensing/bioimaging显示文摘Persistent luminescence nanoprobes (PLNPs) can remain luminescent after ceasing excitation.Due to the ultra-long decay time of persistent luminescence (PersL),autofluorescence interference can be efficiently eliminated by collecting PersL signal after autofluorescence decays completely,thus the imaging contrast and sensing sensitivity can be significantly improved.Since near-infrared (NIR) light shows reduced scattering and absorption coefficient in penetrating biological organs or tissues,near-infrared persistent luminescence nanoprobes (NIR PLNPs) possess deep tissue penetration and offer a bright prospect in the areas of in vivo biosensing/bioimaging.In this review,we firstly summarize the design of different types of NIR PLNPs for biosensing/bioimaging,such as transition metal ions-doped NIR PLNPs,lanthanide ions-doped NIR PLNPs,organic molecules-based NIR PLNPs,and semiconducting polymer self-assembled NIR PLNPs.Notably,organic molecules-based NIR PLNPs and semiconductor self-assembled NIR PLNPs,for the first time,were introduced to the review of PLNPs.Secondly,the effects of different types of charge carriers on NIR PersL and luminescence decay of NIR PLNPs are significantly emphasized so as to build up an in-depth understanding of their luminescence mechanism.It includes the regulation of valence band and conduction band of different host materials,alteration of defect types,depth and concentration changes caused by ion doping,effective radiation transitions and energy transfer generated by different luminescence centers.Given the design and potential of NIR PLNPs as long-lived luminescent materials,the current challenges and future perspective in this rapidly growing field are also discussed.Ling Liang Na Chen Yiyi Jia Qinqin Ma Jie Wang Quan Yuan Weihong Tan 2019Nano Research2019,12,6:11
8Numerical Simulation of Typhoon Muifa(2011) Using a Coupled Ocean-Atmosphere-Wave-Sediment Transport(COAWST) Modeling System显示文摘The newly developed Coupled Ocean-Atmosphere-Wave-Sediment Transport(COAWST) Modeling System is applied to investigate typhoon-ocean interactions in this study. The COAWST modeling system represents the state-of-the-art numerical simulation technique comprising several coupled models to study coastal and environmental processes. The modeling system is applied to simulate Typhoon Muifa(2011), which strengthened from a tropical storm to a super typhoon in the Northwestern Pacific, to explore the heat fluxes exchanged among the processes simulated using the atmosphere model WRF, ocean model ROMS and wave model SWAN. These three models adopted the same horizontal grid. Three numerical experiments with different coupling configurations are performed in order to investigate the impact of typhoon-ocean interaction on the intensity and ocean response to typhoon. The simulated typhoon tracks and intensities agree with observations. Comparisons of the simulated variables with available atmospheric and oceanic observations show the good performance of using the coupled modeling system for simulating the ocean and atmosphere processes during a typhoon event. The fully coupled simulation that includes a ocean model identifies a decreased SST as a result of the typhoon-forced entrainment. Typhoon intensity and wind speed are reduced due to the decrease of the sea surface temperature when using a coupled ocean model. The experiments with ocean coupled to atmosphere also results in decreased sea surface heat flux and air temperature. The heat flux decreases by about 29% compared to the WRF only case. The reduction of the energy induced by SST decreases, resulting in weakening of the typhoon. Coupling of the waves to the atmosphere and ocean model induces a slight increase of SST in the typhoon center area with the ocean-atmosphere interaction increased as a result of wave feedback to atmosphere.LIU Na LING Tiejun WANG Hui ZHANG Yunfei GAO Zhiyi WANG Yi 2015Journal of Ocean University of China2015,14,2:10
9Insights into Cronobacter sakazakii Biofilm Formation and Control Strategies in the Food Industry显示文摘Cronobacter sakazakii(C.sakazakii)is a foodborne opportunistic pathogen that can cause life-threatening invasive diseases,such as necrotizing enterocolitis,meningitis,and sepsis in infants.The potential risk of C.sakazakii contamination of powdered infant formula(PIF)is an issue that has attracted considerable attention from manufacturers,regulators,and consumers.C.sakazakii biofilms on the surfaces of equipment and in diverse food-production environments constitute a mode of cell growth that protects the pathogen from hostile environments,and are an important source of persistent contamination of food products.Bacterial biofilms are difficult to remove due to their resistant properties.Conventional cleaning and sterilizing procedures may be insufficient for biofilm control,and may lead to further biofilm development and dispersal.Consequently,novel control strategies are being developed,such as nanotechnology-based delivery systems,interspecies interactions,antimicrobial molecules of microbial origin,natural extracts,and phages.This review focuses on describing the mechanisms underlying the biofilm formation and behavior of C.sakazakii and discussing potential control strategies.Na Ling Stephen Forsythe Qingping Wu Yu Ding Jumei Zhang Haiyan Zeng 2020Engineering2020,6,4:10
10Structural Modulation of Gut Microbiota in Rats with Allergic Bronchial Asthma Treated with Recuperating Lung Decoction显示文摘Objective To investigate whether recuperating lung decoction(RLD) can modulate the composition of gut microbiota in rats during asthma treatment.Methods Fifteen Sprague-Dawley rats were divided randomly and equally into control group,model group,dexamethasone(DEX) group,RLD medium-dose group,and RLD high-dose group.The asthma model was established in all groups,except for the control group.The rats in the DEX and RLD groups were treated orally with DEX and RLD,respectively.The rats in the control and model groups were treated orally with 0.9% saline.The intestinal bacterial communities were compared among groups using 16 S r RNA gene amplification and 454 pyrosequencing.Results The microbial flora differed between the control and model groups,but the flora in the RLD groups was similar to that in the control group.No significant differences were observed between the RLD high-dose and medium-dose groups.RLD treatment resulted in an increase in the level beneficial bacteria in the gut,such as Lactobacillus and Bifidobacterium spp.Conclusion Oral administration of RLD increased the number of intestinal lactic acid-producing bacteria,such as Lactobacillus and Bifidobacterium,in asthma model rats.KONG Yan Hua SHI Qi HAN Na ZHANG Ling ZHANG Yuan Yuan GAO Tong Xin CHEN Chen LI You Lin 2016Biomedical and Environmental Sciences2016,29,8:9

12Adenomyosis-derived extracellular vesicles endow endometrial epithelial cells with an invasive phenotype through epithelial-mesenchymal transition显示文摘Extracellular vesicles from highly metastatic tumor cells have been shown to mediate epithelial-mesenchymal transition(EMT)-related events in recipient cells.In endometrial epithelial cells,EMT processes are known to be involved in the development of adenomyosis.We aimed to investigate whether adenomyosis-derived extracellular vesicles(AMEVs)are able to induce an EMT process in endometrial epithelial cells.In this study,AMEVs were isolated from patients with adenomyosis and characterized by transmission electron microscopy,Western blot,and nanoparticle tracking.Primary endometrial epithelial cells(EECs)were derived from normal endometrium tissues from patients with leiomyoma and co-cultured with AMEVs in vitro.AMEV uptake was examined by fluorescence confocal microscopy.The invasion of EECs was confirmed by Transwell assay.Immunohistochemistry,Western blot,and qRT-PCR were performed on EECs to illustrate the expression levels of cytokeratin 19,E-cadherin,vimentin,and zinc finger E-boxbinding homeobox 1(ZEB1).The results indicated that the cellular fluorescence intensity gradually increased after 48 h of co-culture,but decreased after 72 h.After co-culturing with AMEVs for 72 h,EECs expressed significantly lower levels of cytokeratin 19 and E-cadherin,and significantly higher levels of vimentin and ZEB1.Together these results demonstrated that AMEVs induce an EMT process and enhance the invasion of EECs.These changes may contribute to the pathogenesis and progression of adenomyosis.Dayong Chen Hai Qiao Yiting Wang Ling Zhou Na Yin Liaoqiong Fang Zhibiao Wang 2020Genes & Diseases2020,7,4:8
13Famitinib in combination with concurrent chemoradiotherapy in patients with locoregionally advanced nasopharyngeal carcinoma: a phase 1, open-label, dose-escalation Study显示文摘Background:Famitinib is a tyrosine kinase inhibitor against multiple targets,including vascular endothelial growth factor receptor 2/3,platelet-derived growth factor receptor,and stem cell factor receptor(c-kit).Previous studies have demonstrated anti-tumour activities of famitinib against a wide variety of advanced-stage solid cancers.We aimed to determine the safety and efficacy of famitinib with concurrent chemoradiotherapy(CCRT)in patients with locoregionally advanced nasopharyngeal carcinoma(NPC).We also evaluated the feasibility of contrast-enhanced ultrasound(D-CEUS)as a predictor of early tumour response to famitinib and to correlate functional parameters with clinical efficacy.Methods:The trial was conducted in subjects with stage III or IVa-b NPC using a 3+3 design of escalating fami-tinib doses.Briefly,subjects received 2 weeks of famitinib monotherapy followed by 7 weeks of famitinib plus CCRT.D-CEUS of the neck lymph nodes was performed at day 0,8 and 15 after famitinib was administered before starting concurrent chemoradiotherapy.End points included safety,tolerability and anti-tumour activity.Results:Twenty patients were enrolled(six each for 12.5,16.5 and 20 mg and two for 25 mg).Two patients in the 25 mg cohort developed dose-limiting toxicities,including grade 4 thrombocytopenia and grade 3 hypertension.The most common grade 3/4 adverse events were leukopenia,neutropenia and radiation mucositis.D-CEUS tests showed that more than 60%of patients achieved a perfusion parameter response after 2 weeks taking famitinib alone,and the parameter response was associated with disease improvement.In the famitinib monotherapy stage,three patients(15%)showed partial responses.The complete response rate was 65%at the completion of treatment and 95%3 months after the treatment ended.After a median follow-up of 44 months,the 3-year progression-free survival(PFS)and distant metastasis-free survival were 70%and 75%,respectively.Subjects with a decrease of perfusion parameter response,such as peak intensity decreased at least 30%after 1 week of famitinib treatment,had higher 3-year PFS(90.9%vs.44.4%,95%CI 73.7%-100%vs.11.9%-76.9%,P<0.001)than those with an increase or a reduction of less than 30%.Conclusions:The recommended famitinib dose for phase II trial is 20 mg with CCRT for patients with local advanced NPC.D-CEUS is a reliable and early measure of efficacy for famitinib therapies.Further investigation is required to confirm the effects of famitinib plus chemoradiotherapy.Qiuyan Chen Linquan Tang Na Liu Feng Han Ling Guo Shanshan Guo Jianwei Wang Huai Liu Yanfang Ye Lu Zhang Liting Liu Pan Wang Yingqin Li Qingmei He Xiaoqun Yang Qingnan Tang Yang Li YuJing Liang XueSong Sun Chuanmiao Xie Yunxian Mo Ying Guo Rui Sun Haoyuan Mo Kajia Cao Xiang Guo Musheng Zeng Haiqiang Mai Jun Ma 2018Cancer Communications2018,38,1:6

15Comparative genomic and transcriptomic analyses uncover the molecular basis of high nitrogen-use efficiency in the wheat cultivar Kenong 9204显示文摘Studying the regulatory mechanisms that drive nitrogen-use efficiency(NUE)in crops is important for sustainable agriculture and environmental protection.In this study,we generated a high-quality genome assembly for the high-NUE wheat cultivar Kenong 9204 and systematically analyzed genes related to nitrogen uptake and metabolism.By comparative analyses,we found that the high-affinity nitrate transporter gene family had expanded in Triticeae.Further studies showed that subsequent functional differentiation endowed the expanded family members with saline inducibility,providing a genetic basis for improving the adaptability of wheat to nitrogen deficiency in various habitats.To explore the genetic and molecular mechanisms of high NUE,we compared genomic and transcriptomic data from the high-NUE cultivar Kenong 9204(KN9204)and the low-NUE cultivar Jing 411 and quantified their nitrogen accumulation under high-and low-nitrogen conditions.Compared with Jing 411,KN9204 absorbed significantly more nitrogen at the reproductive stage after shooting and accumulated it in the shoots and seeds.Transcriptome data analysis revealed that nitrogen deficiency clearly suppressed the expression of genes related to cell division in the young spike of Jing 411,whereas this suppression of gene expression was much lower in KN9204.In addition,KN9204 maintained relatively high expression of NPF genes for a longer time than Jing 411 during seed maturity.Physiological and transcriptome data revealed that KN9204 was more tolerant of nitrogen deficiency than Jing 411,especially at the reproductive stage.The high NUE of KN9204 is an integrated effect controlled at different levels.Taken together,our data provide new insights into the molecular mechanisms of NUE and important gene resources for improving wheat cultivars with a higher NUE trait.Xiaoli Shi Fa Cui Xinyin Han Yilin He Long Zhao Na Zhang Hao Zhang Haidong Zhu Zhexin Liu Bin Ma Shusong Zheng Wei Zhang Jiajia Liu Xiaoli Fan Yaoqi Si Shuiquan Tian Jianqing Niu Huilan Wu Xuemei Liu Zhuo Chen Deyuan Meng Xiaoyan Wang Liqiang Song Lijing Sun Jie Han Hui Zhao Jun Ji Zhiguo Wang Xiaoyu He Ruilin Li Xuebin Chi Chengzhi Liang Beifang Niu Jun Xiao Junming Li Hong-Qing Ling 2022Molecular Plant2022,15,9:6
16In-situ growth of vertically aligned nickel cobalt sulfide nanowires on carbon nanotube fibers for high capacitance all-solid-state asymmetric fiber-supercapacitors显示文摘Fiber-supercapacitors(FSCs)are promising power sources for miniature portable and wearable electronic devices.However,the development and practical application of these FSCs have been severely hindered by their low volumetric capacitance and narrow operating voltage.In this work,vertically aligned nickel cobalt sulfide(Ni Co2S4)nanowires grown on carbon nanotube(CNT)fibers were achieved through an in-situ two-step hydrothermal reaction method.The as-prepared Ni Co2S4@CNT fiber electrode exhibits a high volumetric capacitance of 2332 F cm-3,benefiting from its superior electric conductivity,large surface area,and rich Faradic redox reaction sites.Furthermore,a Ni Co2S4@CNT//VN@CNT(vanadium nitride nanosheets grown on CNT fibers)asymmetric fiber-supercapacitor(AFSC)was successfully fabricated.The device exhibits an operating voltage up to 1.6 V and a high volumetric energy density of 30.64m Wh cm-3.The device also possesses outstanding flexibility as evidenced by no obvious performance degradation under various bending angles and maintaining high capacitance after 5000 bending cycles.This work promotes the practical application of flexible wearable energy-storage devices.Na Liu Zhenghui Pan Xiaoyu Ding Jie Yang Guoguang Xu Linge Li Qi Wang Meinan Liu Yuegang Zhang 2020Journal of Energy Chemistry2020,29,2:5
17Recent advances and perspectives on vanadium-and manganese-based cathode materials for aqueous zinc ion batteries显示文摘The growing demand for energy storage has inspired researchers’exploration of advanced batteries.Aqueous zinc ion batteries(ZIBs)are promising secondary chemical battery system that can be selected and pursued.Rechargeable ZIBs possess merits of high security,low cost,environmental friendliness,and competitive performance,and they are received a lot of attention.However,the development of suitable zinc ion intercalation-type cathode materials is still a big challenge,resulting in failing to meet the commercial needs of ZIBs.Both vanadium-based and manganese-based compounds are representative of the most advanced and most widely used rechargeable ZIBs electrodes.The valence state of vanadium is+2~+5,which can realize multi-electron transfer in the redox reaction and has a high specific capacity.Most of the manganese-based compounds have tunnel structure or three-dimensional space frame,with enough space to accommodate zinc ions.In order to understand the energy storage mechanism and electrochemical performance of these two materials,a specialized review focusing on state-of-the-art developments is needed.This review offers access for researchers to keep abreast of the research progress of cathode materials for ZIBs.The latest advanced researches in vanadium-based and manganese-based cathode materials applied in aqueous ZIBs are highlighted.This article will provide useful guidance for future studies on cathode materials and aqueous ZIBs.Na Liu Bin Li Zhangxing He Lei Dai Haiyan Wang Ling Wang 2021Journal of Energy Chemistry2021,30,8:5
18Givinostat inhibition of hepatic stellate cell proliferation and protein acetylation显示文摘AIM: To explore the effect of the histone deacetylase inhibitor givinostat on proteins related to regulation of hepatic stellate cell proliferation.METHODS: The cell counting kit-8 assay and flow cytometry were used to observe changes in proliferation, apoptosis, and cell cycle in hepatic stellate cells treated with givinostat. Western blot was used to observe expression changes in p21, p57, CDK4, CDK6, cyclin D1, caspase-3, and caspase-9 in hepatic stellate cells exposed to givinostat. The scratch assay was used to analyze the effect of givinostat on cell migration. Effects of givinostat on the reactive oxygen species profile, mitochondrial membrane potential, and mitochondrial permeability transition pore opening in JS-1 cells were observed by laser confocal microscopy.RESULTS: Givinostat significantly inhibited JS-1 cell proliferation and promoted cell apoptosis, leading to cell cycle arrest in G0/G1 phases. Treatment with givinostat downregulated protein expression of CDK4, CDK6, and cyclin D1, whereas expression of p21 and p57 was significantly increased. The givinostat-induced apoptosis of hepatic stellate cells was mainly mediatedthrough p38 and extracellular signal-regulated kinase 1/2. Givinostat treatment increased intracellular reactive oxygen species production, decreased mitochondrial membrane potential, and promoted mitochondrial permeability transition pore opening. Acetylation of superoxide dismutase(acetyl K68) and nuclear factor-κB p65(acetyl K310) was upregulated, while there was no change in protein expression. Moreover, the notable beneficial effect of givinostat on liver fibrosis was also confirmed in the mouse models.CONCLUSION: Givinostat has antifibrotic activities via regulating the acetylation of nuclear factor-κB and superoxide dismutase 2, thus inhibiting hepatic stellate cell proliferation and inducing apoptosis.Yu-Gang Wang Ling Xu Ting Wang Jue Wei Wen-Ying Meng Na Wang Min Shi 2015World Journal of Gastroenterology2015,21,27:5

20Enantiomer-selective Living Polymerization of rac-Phenyl Isocyanide Using Chiral Palladium Catalyst显示文摘We report the polymerization of phenyl isocyanides with the chiral palladium(II) initiating system. The resulting polymers with optically active properties were obtained by polymerization of the racemic isocyanide monomer(rac-1), and enantiomerically unbalanced polymerization of the monomer was found, providing substantial evidence for the enantiomer-selective polymerization of rac-1 mediated through chiral catalyst. A comparison between the enantiomerically pure monomers, 4-isocyanobenzoyl-L-alanine decyl ester(1 s) and 4-isocyanobenzoyl-D-alanine decyl ester(1 r), revealed a drastic discrepancy in the reactivity ratio of their homopolymerizations.It turned out that the monomer reactivity ratio of 1 s was higher than that of 1 r with chiral ligands. The results clearly demonstrated the inclination for incorporation of the 1 s enantiomer during the polymerization process and thus resulted in the enantiomer-selective polymerization in this system. The effects of the catalyst chirality on the optically active properties of polymerization were investigated,and it was concluded that the formation of higher-ordered conformation with a handed helicity might be attributed to the chiral induction of chiral palladium(II) catalyst. Moreover, the polymers obtained through the enantiomer-selective polymerization of the enantiomerically pure monomer were with a significant improvement of the optical activity if the chirality of the monomer and the catalyst matched with each other.Jian Huang Ling Shen Hui Zou Na Liu 2018Chinese Journal of Polymer Science2018,36,7:4
