1Preliminary results pertaining to coseismic displacement and preseismic strain accumulation of the Lushan M_S7.0 earthquake,as reflected by GPS surveying显示文摘This paper presents the coseismic displacement and preseismic deformation fields of the Lushan MS7.0 earthquake that occurred on April 20,2013.The results are based on GPS observations along the Longmenshan fault and within its vicinity.The coseismic displacement and preseismic GPS results indicate that in the strain release of this earthquake,the thrust rupture is dominant and the laevorotation movement is secondary.Furthermore,we infer that any possible the rupture does not reach the earth’s surface,and the seismogenic fault is most likely one fault to the east of the Guanxian-Anxian fault.Some detailed results are obtainable.(1)The southern segment of the Longmenshan fault is locked preceding the Lushan earthquake.After the Wenchuan earthquake,the strain accumulation rate in the southeast direction accelerates in the epicenter of the Lushan earthquake,and the angle between the principal compressional strain and the seismogenic fault indicates that a sinistral deformation background in the direction of the seismogenic fault precedes the Lushan earthquake.Therefore,it is evident that the Wenchuan MS8.0 earthquake accelerated the pregnancy of the Lushan earthquake.(2)The coseismic displacements reflected by GPS data are mainly located in a region that is 230 km(NW direction)×100 km(SW direction),and coseismic displacements larger than 10 mm lie predominantly in a100-km region(NW direction).(3)On a large scale,the coseismic displacement shows thrust characteristics,but the associated values are remarkably small in the near field(within 70 km)of the earthquake fault.Meanwhile,the thrust movement in this70-km region does not correspond with the attenuation characteristics of the strain release,indicating that the rupture of this earthquake does not reach the earth’s surface.(4)The laevorotation movements are remarkable in the 50-km region,which is located in the hanging wall that is close to the earthquake fault,and the corresponding values in this case correlate with the attenuation characteristics of the strain release.WU YanQiang JIANG ZaiSen WANG Min CHE Shi LIAO Hua LI Qiang LI Peng YANG YongLin XIANG HePing SHAO ZhiGang WANG WuXing WEI WenXin LIU XiaoXia 2013Chinese Science Bulletin2013,58,28:33
2Evaluation of drinking water treatment combined filter backwash water recycling technology based on comet and micronucleus assay显示文摘Based on the fact that recycling of combined filter backwash water(CFBW)directly to drinking water treatment plants(WTP)is considered to be a feasible method to enhance pollutant removal efficiency,we were motivated to evaluate the genotoxicity of water samples from two pilot-scale drinking water treatment systems,one with recycling of combined backwash water,the other one with a conventional process.An integrated approach of the comet and micronucleus(MN)assays was used with zebrafish(Danio rerio)to investigate the water genotoxicity in this study.The total organic carbon(TOC),dissolved organic carbon(DOC),and trihalomethane formation potential(THMFP),of the recycling process were lower than that of the conventional process.All the results showed that there was no statistically significant difference(P>0.05)between the conventional and recycling processes,and indicated that the genotoxicity of water samples from the recycling process did not accumulate in 15 day continuous recycling trial.It was worth noting that there was correlation between the concentrations of TOC,DOC,UV_(254),and THMFPs in water and the DNA damage score,with corresponding R^2 values of 0.68,0.63,0.28,and 0.64.Nevertheless,both DNA strand breaks and MN frequency of all water samples after disinfection were higher than that of water samples from the two treatment units,which meant that the disinfection by-products(DBPs)formed by disinfection could increase the DNA damage.Both the comet and MN tests suggest that the recycling process did not increase the genotoxicity risk,compared to the traditional process.Ting Chen Yongpeng Xu Zhiquan Liu Shijun Zhu Wenxin Shi Fuyi Cui 2016Journal of Environmental Sciences2016,28,4:8
3Photocatalytic activity enhanced via surface hybridization显示文摘Surface hybrid inorganic semiconductors photocatalysts withπconjugated structure have recently been widely used in the field of photocatalytic environmental remediation and energy conversion.Surface hybridization is considered to be an efficient way to significantly enhance the photocatalytic activity by several times,completely inhibit photocorrosion of inorganic photocatalysts and expand the spectral response range of photocatalysts.This review provides a comprehensive overview of the surface hybridization definition,the principle of enhancing photocatalytic performance and the control factors of surface hybridization to promote photoactivity.Summarize the preparation and structural identification method of the surface hybrid photocatalyst.Special emphasis is placed on the various photocatalytic system construction of surface hybridization.The development of surface hybrid photocatalysts for pollutant degradation and energy conversion are further presented.Finally,the challenges and future development prospects of surface hybridization in photocatalysis are discussed.We hope this critical review can provide a clear picture of the state-of-the-art achievements and facilitate the applications of surface hybrid photocatalysts in environmental remediation and energy conversion.Yan Guo Huarui Li Wei Ma Wenxin Shi Yongfa Zhu Wonyong Choi 2020Carbon Energy2020,2,3:5

6Single-atom Sn-Zn pairs in CuO catalyst promote dimethyldichlorosilane synthesis显示文摘Single-atom catalysts are of great interest because they can maximize the atom-utilization efficiency and generate unique catalytic properties;however,much attention has been paid to single-site active components,rarely to catalyst promoters.Promoters can significantly affect the activity and selectivity of a catalyst,even at their low concentrations in catalysts.In this work,we designed and synthesized CuO catalysts with atomically dispersed co-promoters of Sn and Zn.When used as the catalyst in the Rochow reaction for the synthesis of dimethyldichlorosilane,this catalyst exhibited much-enhanced activity,selectivity and stability compared with the conventional CuO catalysts with promoters in the form of nanoparticles.Density functional theory calculations demonstrate that single-atomic Sn substitution in the CuO surface can enrich surface Cu vacancies and promote dispersion of Zn to its atomic levels.Sn and Zn single sites as the co-promoters cooperatively generate electronic interaction with the CuO support,which further facilitates the adsorption of the reactant molecules on the surface,thereby leading to the superior catalytic performance.Qi Shi Yongjun Ji Wenxin Chen Yongxia Zhu Jing Li Hezhi Liu Zhi Li Shubo Tian Ligen Wang Ziyi Zhong Limin Wang Jianmin Ma Yadong Li Fabing Su 2020National Science Review2020,7,3:2
7Efficient and targeted drug/siRNA co-delivery mediated by reversibly crosslinked polymersomes toward anti-inflammatory treatment of ulcerative colitis (UC)显示文摘Co-delivery of anti-inflammatory siRNA and hydrophilic drug provides a promising approach for the treatment of ulcerative colitis (UC). However, lack of a suitable and efficient co-delivery carrier poses critical challenge against their utilization. We herein developed macrophage-targeting, reversibly crossli nked polymersomes (TKPR-RCP) based on the TKPR-modified, poly(ethyle ne glycol)-b-poly(trimethylene carbonate-codithiolane trimethylene carbonate)-b-polyethylenimine (PEG-P(TMC-DTC)-PEI) triblock copolymer, which could efficiently encapsulate TNF-α siRNA and dexamethasone sodium phosphate (DSP) in their hydrophilic core. The cationic PEI segments provided additional electrostatic interactions with cargo molecules to promote the encapsulatiion, and disulfide crosslinking of the polymersome membrane endowed the TKPR-RCP with high colloidal stability. Because the cationic PEI was embedded in the hydrophilic core, the polymersomes displayed neutral surface charge and thus possessed high serum stability. The TKPR-RCP co-encapsulating TNF-α siRNA and DSP could be efficiently internalized by macrophages (~98%) and undergo redox-responsive membrane de-crosslinking to accelerate cargo release in the cytoplasm, thus inducing efficient gene silencing and anti-inflammatory effect .Intravenous injectio n of the co-delivery TKPR-RCP mediated pote nt and cooperative anti-inflammatory effect in inflamed colons of UC mice, and significantly prevented animals from colonic injury. This study therefore provides a promising approach for the co-delivery of hydrophilic drug/siRNA toward the treatment of inflammatory bowel diseases.Xin Xu Weijing Yang Qiujun Liang Yanan Shi Wenxin Zhang Xiao Wang Fenghua Meng Zhiyuan Zhong Lichen Yin 2019Nano Research2019,12,3:2
8Assessment of strong earthquake risk in the Chinese mainland from 2021 to 2030显示文摘The long-term earthquake prediction from 2021 to 2030 is carried out by researching the active tectonic block boundary zones in the Chinese mainland.Based on the strong earthquake recurrence model,the cumulative probability of each target fault in the next 10 years is given by the recurrence period and elapsed time of each fault,which are adopted from relevant studies such as seismological geology,geodesy,and historical earthquake records.Based on the long-term predictions of large earthquakes throughout the world,this paper proposes a comprehensive judgment scheme based on the fault segments with the seismic gap,motion strongly locked,sparse small-moderate earthquakes,and apparent Coulomb stress increase.This paper presents a comprehensive analysis of the relative risk for strong earthquakes that may occur in the coming 10 years on the major faults in the active tectonic block boundary zones in the Chinese mainland.The present loading rate of each fault is first constrained by geodetic observations;the cumulative displacement of each fault is then estimated by the elapsed time since the most recent strong earthquake.Zhigang Shao Yanqiang Wu Lingyun Ji Faqi Diao Fuqiang Shi Yujiang Li Feng Long Hui Zhang Wuxing Wang Wenxin Wei Peng Wang Xiaoxia Liu Qi Liu Zhengyang Pan Xiaofei Yin Yue Liu Wei Feng Zhenyu Zou Jia Cheng Renqi Lu Yueren Xu Xi Li 2023Earthquake Research Advances2023,3,1:2

13The COVID‐19 vaccine: Attitudes and vaccination in patients with autoimmune inflammatory rheumatic diseases显示文摘Background:We examined attitudes toward the COVID‐19 vaccine,potential factors underlying these attitudes,and ways to increase vaccination willingness in autoimmune inflammatory rheumatic diseases(AIIRD)patients.Methods:A multicenter,web‐based,observational survey using an online questionnaire was conducted among AIIRD patients aged≥18 years from May 24,2021,to June 3,2021.Participants were 3104 AIIRD patients(2921 unvaccinated and 183 vaccinated).Results:Of the unvaccinated patients,32.9%were willing to receive the COVID‐19 vaccine,45.0%were uncertain,and 14.8%were unwilling.When vaccination was recommended by physicians,patients'willingness increased to 93.8%.Participants'main concerns were that the vaccine may aggravate AIIRD disease(63.0%)and may cause vaccine‐related adverse events(19.9%).Female patients were less likely to be vaccinated.However,patients who had children aged≤18 years were more willing to be vaccinated.In addition,vaccination willingness was higher in patients with trust in the safety and efficacy of the COVID‐19 vaccine.Notably,183(5.9%)patients were vaccinated.The major vaccination side effects were injection reaction,myalgia,and fatigue.At a median follow‐up of 88(38,131)days,patients'disease activities were stable.Conclusions:The findings show that AIIRD patients were unwilling to receive the COVID‐19 vaccine because of fears of potential disease exacerbation and additional adverse events.Sociodemographic characteristics and concerns about COVID‐19 disease and vaccines had a significant effect on vaccination willingness.Jiali Chen Wenxin Cai Tian Liu Yunshan Zhou Yuebo Jin Yue Yang Shi Chen Kun Tang Chun Li 2022Rheumatology & Autoimmunity2022,2,2:1

19Quasi-Spherical Brookite TiO_2 Nanostructures Synthesized Using Solvothermal Method in the Presence of Oxalic Acid显示文摘Brookite TiO_2,the latest TiO_2 photocatalyst,promises to be an interesting candidate for photocatalytic applications because of its unique physical and chemical properties. In this study,pure-phase brookite TiO_2 with a quasi-spherical nanostructure was successfully synthesized via a solvothermal method using tetrabutyl titanate(Ti(OC_4H_9)_4,TBOT) as the Ti source in the presence of oxalic acid. NaOH was used to regulate the pH of solution. The structure and morphology of the samples were then analyzed using multiple methods,such as X-ray diff raction(XRD),Raman spectroscopy,scanning electron microscopy(SEM),transmission electron microscopy(TEM),Brunauer–Emmett–Teller(BET) measurements and ultraviolet–visible diff use spectroscopy(UV–Vis). Photocatalytic activities of the as-synthesized brookite TiO_2 were evaluated by degrading aqueous methylene blue solution under UV light irradiation. The effect of thermal treatment temperature on photocatalytic activity of the samples was also investigated. The produced brookite TiO_2 nanopowders calcined at 500 °C for 2 h showed the highest photocatalytic activity,and the corresponding degradation rate of methylene blue(10 mg/L) reached 96.7% after 90 min of illumination. In addition,the formation mechanism of pure-phase brookite TiO_2 was investigated. It was found that the formation of pure-phase brookite TiO_2 in this study was ascribed to the combined action of oxalic acid and sodium hydroxide.Yifei Wang Yunling Zou Qianqian Shang Xin Tan Tao Yu Xianshou Huang Wenxin Shi Yao Xie Gao Yan Xiaoyi Wang 2018Transactions of Tianjin University2018,24,4:1
