| 1 | Zr-MOFs loaded on polyurethane foam by polydopamine for enhanced dye adsorption显示文摘Zirconium-based metal-organic frameworks(Zr-MOFs)have attracted widespread attention due to their high specific surface area,high porosity,abundant metal active sites and excellent hydrothermal stability.However,Zr-MOFs materials are mostly powdery in nature and thus difficult to separate from aqueous media,which limits their application in wastewater treatment.In this study,PDA/Zr-MOFs/PU foam was constructed by growing Zr-MOFs nanoparticles on a dopamine-modified polyurethane foam substrate by in-situ hydrothermal synthesis as an adsorbent for removing dyes from wastewater.The results demonstrated that the polydopamine coating improves the dispersion of the Zr-MOFs nanoparticles on the substrate and enhances the interaction between the Zr-MOFs nanoparticles and the PU foam substrate.As a result,compared with Zr-MOFs/PU foam,the prepared PDA/ZrMOFs/PU foam exhibits higher adsorption capacity for crystal violet(CV)(63.38 mg/g)and rhodamine B(RB)(67.73 mg/g),with maximum adsorption efficiencies of CV and RB of 98.4%(pH=11)and 93.5%(pH=7),respectively,at a concentration of 10 mg/L.The PDA/Zr-MOFs/PU foam can simultaneously remove CV and RB from the mixed solution.Moreover,the PDA/ZrMOFs/PU foam still exhibits high stability and reusability after five cycles. | Jingjing Zhao Linqiong Xu Yaozhuo Su Hongwei Yu Hui Liu Shaoping Qian Wenge Zheng Yongqing Zhao | 2021 | Journal of Environmental Sciences2021，33，3： | 6 |
| 2 | Reliability estimation of mechanical seals based on bivariate dependence analysis and considering model uncertainty显示文摘The reliability estimation of mechanical seals is of crucial importance due to their wide applications in pumps in various mechanical systems.Failure of mechanical seals might cause leakage,and might lead to system failure and other relevant consequences.In this study,the reliability estimation for mechanical seals based on bivariate dependence analysis and considering model uncertainty is proposed.The friction torque and leakage rate are two degradation performance indicators of mechanical seals that can be described by the Wiener process,Gamma process,and inverse Gaussian process.The dependence between the two indicators can be described by different copula functions.Then the model uncertainty is considered in the reliability estimation using the Bayesian Model Average(BMA)method,while the unknown parameters in the model are estimated by Bayesian Markov Chain Monte Carlo(MCMC)method.A numerical simulation study and fatigue crack study are conducted to demonstrate the effectiveness of the BMA method to capture model uncertainty.A degradation test of mechanical seals is conducted to verify the proposed model.The optimal stochastic process models for two performance indicators and copula function are determined based on the degradation data.The results show the necessity of using the BMA method in degradation modeling. | Rentong CHEN Chao ZHANG Shaoping WANG Yujie QIAN | 2021 | Chinese Journal of Aeronautics2021，34，5： | 5 |
| 3 | Free radical scavenging activity of Eagle tea and their flavonoids显示文摘In this study,an online HPLC-DAD-MS coupled with 2,2'-azinobis(3-ethylbenzthiazoline-6-sulfonic acid)diammonium salt(A BTS)assay was employed for evaluating free radical scavenging activity of Eagle tea and their active components.Twenty-three chromatographic peaks were detected,and nineteen components had free radical scavenging activity.Among them,eight compounds were identified as flavonoids(hyperin,isoquercitrin,quercitrin,quercetin,kaempferol),catechins,chlorogenic acid and epicatechin based on MS data and standard chromatographic characters. | Qiong Meng Zhengming Qian Xiaoxiang Li Deqiang Li Weihua Huang Jing Zhao Shaoping Li | 2012 | Acta Pharmaceutica Sinica B2012，2，3： | 4 |
| 4 | Challenges and innovations in treating chronic and acute wound infections:from basic science to clinical practice显示文摘Acute and chronic wound infection has become a major worldwide healthcare burden leading to significantly high morbidity and mortality.The underlying mechanism of infections has been widely investigated by scientist,while standard wound management is routinely been used in general practice.However,strategies for the diagnosis and treatment of wound infections remain a great challenge due to the occurrence of biofilm colonization,delayed healing and drug resistance.In the present review,we summarize the common microorganisms found in acute and chronic wound infections and discuss the challenges from the aspects of clinical diagnosis,non-surgical methods and surgical methods.Moreover,we highlight emerging innovations in the development of antimicrobial peptides,phages,controlled drug delivery,wound dressing materials and herbal medicine,and find that sensitive diagnostics,combined treatment and skin microbiome regulation could be future directions in the treatment of wound infection. | Xiaotong Ding Qinghan Tang Zeyu Xu Ye Xu Hao Zhang Dongfeng Zheng Shuqin Wang Qian Tan Joanneke Maitz Peter K.Maitz Shaoping Yin Yiwei Wang Jun Chen | 2022 | Burns & Trauma2022，10，1： | 3 |
| 5 | Analysis of Cordyceps by multi-column liquid chromatography显示文摘Cordyceps is a famous traditional Chinese medicine(TCM) that has been used in China for hundreds of years.In the present study a multi-column liquid chromatography(MC-LC) system was developed for the qualitative analysis of macromolecules and micromolecules in Cordyceps.The MC-LC system includes a size exclusion pre-column,a size exclusion column(SEC) and a reversed phase column(RP) which were controlled by column-switching valves.The sample was separated by the size exclusion pre-column into two fractions(macromolecules and micromolecules).These fractions were further separated on SEC and RP columns,respectively.A diode array detector(DAD) and a mass spectrometer(MS) were used to detect the components.This MC-LC method was utilized for analysis of Cordyceps samples.Two macromolecular peaks and 15 micromolecular peaks were found in Cordyceps,and 11 of the micromolecular peaks were identified as adenosine-5'-monophosphate(AMP),phenylalanine,uridine,hypoxanthine,inosine,guanine,guanosine,deoxyadenosine-5'-monophosphate(dAMP),adenosine,adenine and cordycepin(or its isomer).This method is useful for quality control of Cordyceps. | Zhengming Qian Shaoping Li | 2017 | Acta Pharmaceutica Sinica B2017，7，2： | 1 |
| 6 | Proteome-wide identification of S-sulfenylated cysteines response to salt stress in Brassica napus root显示文摘Reactive oxygen species(ROS)play a key role in a variety of biological processes,such as the perception of abiotic stress,the integration of different environmental signals,and the activation of stress response networks.Salt stress could induce an increased ROS accumulation in plants,disrupting intracellular redox homeostasis,leading to posttranslational modifications(PTMs)of specific proteins,and eventually causing adaptive changes in metabolism.Here,we performed an iodoTMT-based proteomic approach to identify the sulfenylated proteins in B.napus root responsing to salt stress.Totally,1348 sulfenylated sites in 751 proteins were identified and these proteins were widely existed in different cell compartments and processes.Our study revealed that proteins with changed abundance and sulfenylation level in B.napus root under salt stress were mainly enriched in the biological processes of ion binding,glycolysis,ATP binding,and oxidative stress response.This study displays a landscape of sulfenylated proteins response to salt stress in B.napus root and provides some theoretical support for further understanding of the molecular mechanisms of redox regulation under salt stress in plants. | Qian Qu Xiaowei Wu Qing Zhou Shaoping Lu Xuan Yao Liang Guo Liangqian Yu | 2023 | Oil Crop Science2023，8，4： | 0 |
