1Animal models for the atherosclerosis research:a review显示文摘Atherosclerosis is a leading cause of death worldwide,and its mechanisms are still unclear.However,various animal models have significantly advanced our understanding of the mechanisms involved in atherosclerosis and have allowed the evaluation of therapeutic options.The aim of this paper is to review those animal models(i.e.,rabbits,mice,rats,guinea pigs,hamsters,avian,carnivores,swine,and,non-human primates)that have been used to study atherosclerosis.Though there is no single perfect animal model that completely replicates the stages of human atherosclerosis,cholesterol feeding and mechanical endothelial injury are two common features shared by most models of atherosclerosis.Further,with the development of genetically modified animals,these models are significantly broadening our understanding of the pathogenesis of atherosclerosis.Xiangdong Li Yuanwu Liu Hua Zhang Liming Ren Qiuyan Li Ning Li 2011Protein & Cell2011,2,3:21
2Reduced graphene oxide-nano zero value iron(rGO-nZVI) micro-electrolysis accelerating Cr(Ⅵ) removal in aquifer显示文摘Nanoscale zero-valent iron(nZVI) assembled on graphene oxide(GO)(rGO-nZVI) composites were synthesized by reduction of GO and ferrous ions with potassium borohydride,for use in Cr(VI) removal from aqueous solution.The results showed that the two-dimensional structure of GO could provide a skeleton support for Fe^0,thus overcoming the bottleneck of aggregation for nZVI.Also,rGO-nZVI would form a ferric-carbon micro-electrolysis system in Cr(VI)-contaminated aquifers,enhancing and accelerating electron transfer,exhibiting high rate and capacity for Cr(VI) removal.The optimum dosage of the applied r GO-nZVI was linearly correlated with the initial Cr(VI) concentration.Characterization of rGO-nZVI before and after reaction with Cr(VI) revealed the process of Cr(VI) removal:r GO-nZVI firstly transferred electrons from Fe^0 cores via their Fe(II)/Fe(III) shells to the GO sheet;there,negatively charged Cr(VI) received electrons and changed into positively charged Cr(III),which was adsorbed by the negatively charged GO sheet,avoiding the capping and passivating of nZVI.rGO-nZVI formed a good electrically conductive network,and thus had long-term electron releasing properties,which was important for groundwater remediation.Liming Ren Jun Dong Zifang Chi Huazheng Huang 2018Journal of Environmental Sciences2018,30,11:12
3The enhanced X-ray Timing and Polarimetry mission—eXTP显示文摘In this paper we present the enhanced X-ray Timing and Polarimetry mission—eXTP. eXTP is a space science mission designed to study fundamental physics under extreme conditions of density, gravity and magnetism. The mission aims at determining the equation of state of matter at supra-nuclear density, measuring effects of QED, and understanding the dynamics of matter in strong-field gravity. In addition to investigating fundamental physics, eXTP will be a very powerful observatory for astrophysics that will provide observations of unprecedented quality on a variety of galactic and extragalactic objects. In particular, its wide field monitoring capabilities will be highly instrumental to detect the electro-magnetic counterparts of gravitational wave sources.The paper provides a detailed description of:(1) the technological and technical aspects, and the expected performance of the instruments of the scientific payload;(2) the elements and functions of the mission, from the spacecraft to the ground segment.ShuangNan Zhang Andrea Santangelo Marco Feroci YuPeng Xu FangJun Lu Yong Chen Hua Feng Shu Zhang Sφren Brandt Margarita Hernanz Luca Baldini Enrico Bozzo Riccardo Campana Alessandra De Rosa YongWei Dong Yuri Evangelista Vladimir Karas Norbert Meidinger Aline Meuris Kirpal Nandra Teng Pan Giovanni Pareschi Piotr Orleanski QiuShi Huang Stephane Schanne Giorgia Sironi Daniele Spiga Jiri Svoboda Gianpiero Tagliaferri Christoph Tenzer Andrea Vacchi Silvia Zane Dave Walton ZhanShan Wang Berend Winter Xin Wu Jean J.M.in't Zand Mahdi Ahangarianabhari Giovanni Ambrosi Filippo Ambrosino Marco Barbera Stefano Basso Jörg Bayer Ronaldo Bellazzini Pierluigi Bellutti Bruna Bertucci Giuseppe Bertuccio Giacomo Borghi XueLei Cao Franck Cadoux Francesco Ceraudo TianXiang Chen Yu Peng Chen Jerome Chevenez Marta Civitani Wei Cui WeiWei Cui Thomas Dauser Ettore Del Monte Sergio Di Cosimo Sebastian Diebold Victor Doroshenko Michal Dovciak YuanYuan Du Lorenzo Ducci QingMei Fan Yannick Favre Fabio Fuschino JoséLuis Ga'lvez Min Gao MingYu Ge Olivier Gevin Marco Grassi QuanYing Gu YuDong Gu DaWei Han Bin Hong Wei Hu Long Ji ShuMei Jia WeiChun Jiang Thomas Kennedy Ingo Kreykenbohm Irfan Kuvvetli Claudio Labanti Luca Latronico Gang Li MaoShun Li Xian Li Wei Li ZhengWei Li Olivier Limousin HongWei Liu XiaoJing Liu Bo Lu Tao Luo Daniele Macera Piero Malcovati Adrian Martindale Malgorzata Michalska Bin Meng Massimo Minuti Alfredo Morbidini Fabio Muleri Stephane Paltani Emanuele Perinati Antonino Picciotto Claudio Piemonte JinLu Qu Alexandre Rachevski Irina Rashevskaya Jerome Rodriguez Thomas Schanz ZhengXiang Shen LiZhi Sheng JiangBo Song LiMing Song Carmelo Sgro Liang Sun Ying Tan Phil Uttley Bo Wang DianLong Wang GuoFeng Wang Juan Wang LangPing Wang YuSa Wang Anna L.Watts XiangYang Wen Jörn Wilms ShaoLin Xiong JiaWei Yang Sheng Yang YanJi Yang Nian Yu WenDa Zhang Gianluigi Zampa Nicola Zampa Andrzej A.Zdziarski AiMei Zhang ChengMo Zhang Fan Zhang Long Zhang Tong Zhang Yi Zhang XiaoLi Zhang ZiLiang Zhang BaoSheng Zhao ShiJie Zheng Yu Peng Zhou Nicola Zorzi J.Frans Zwart 2019Science China(Physics,Mechanics & Astronomy)2019,62,2:11
4The newly emerged SARS-Like coronavirus HCoV-EMC also has an “Achilles’ heel”: current effective inhibitor targeting a 3C-like protease显示文摘From the global outbreak of SARS-CoV caused infection disease in 2003,coronaviruses(CoVs)are known to be a great threat to the human health.Recently,a new SARS-like coronavirus,human betacoronavirus 2c EMC/2012(HCoV-EMC),has been identified and the appearance of this new CoV raises concerns that a new spread of CoV may occurs in the future.By solving the crystal structure of HCoV-EMC main protease with a wide-spectrum anti-CoV inhibitor N3,we confi rmed that that N3 blocks the function of HCoV-EMC main protease through a similar mechanism to other CoVs.Together with the good pharmaceutical features,N3 is conceivable to be effective to HCoV-EMC and other CoVs appearing in the future.These fi ndings make it convincing that CoVs will not be a threat to human health.Zhilin Ren Liming Yan Ning Zhang Yu Guo Cheng Yang Zhiyong Lou Zihe Rao 2013Protein & Cell2013,4,4:10

6Mussel‑Inspired Redox‑Active and Hydrophilic Conductive Polymer Nanoparticles for Adhesive Hydrogel Bioelectronics显示文摘Conductive polymers(CPs)are generally insoluble,and developing hydrophilic CPs is significant to broaden the applications of CPs.In this work,a mussel-inspired strategy was proposed to construct hydrophilic CP nanoparticles(CP NPs),while endowing the CP NPs with redox activity and biocompatibility.This is a universal strategy applicable for a series of CPs,including polyaniline,polypyrrole,and poly(3,4-ethylenedioxythiophene).The catechol/quinone contained sulfonated lignin(LS)was doped into various CPs to form CP/LS NPs with hydrophilicity,conductivity,and redox activity.These CP/LS NPs were used as versatile nanofillers to prepare the conductive hydrogels with long-term adhesiveness.The CP/LS NPs-incorporated hydrogels have a good conductivity because of the uniform distribution of the hydrophilic NPs in the hydrogel network,forming a well-connected electric path.The hydrogel exhibits long-term adhesiveness,which is attributed to the mussel-inspired dynamic redox balance of catechol/quinone groups on the CP/LS NPs.This conductive and adhesive hydrogel shows good electroactivity and biocompatibility and therefore has broad applications in electrostimulation of tissue regeneration and implantable bioelectronics.Donglin Gan Tao Shuai Xiao Wang Ziqiang Huang Fuzeng Ren Liming Fang Kefeng Wang Chaoming Xie Xiong Lu 2020Nano-Micro Letters2020,12,12:4
7Temporal and spatial cellular and molecular pathological alterations with single-cell resolution in the adult spinal cord after injury显示文摘Spinal cord injury(SCI)involves diverse injury responses in different cell types in a temporally and spatially specific manner.Here,using single-cell transcriptomic analyses combined with classic anatomical,behavioral,electrophysiological analyses,we report,with single-cell resolution,temporal molecular and cellular changes in crush-injured adult mouse spinal cord.Data revealed pathological changes of 12 different major cell types,three of which infiltrated into the spinal cord at distinct times post-injury.We discovered novel microglia and astrocyte subtypes in the uninjured spinal cord,and their dynamic conversions into additional stage-specific subtypes/states.Most dynamic changes occur at 3-days post-injury and by day-14 the second wave of microglial activation emerged,accompanied with changes in various cell types including neurons,indicative of the second round of attacks.By day-38,major cell types are still substantially deviated from uninjured states,demonstrating prolonged alterations.This study provides a comprehensive mapping of cellular/molecular pathological changes along the temporal axis after SCI,which may facilitate the development of novel therapeutic strategies,including those targeting microglia.Chen Li Zhourui Wu Liqiang Zhou Jingliang Shao Xiao Hu Wei Xu Yilong Ren Xingfei Zhu Weihong Ge Kunshan Zhang Jiping Liu Runzhi Huang Jing Yu Dandan Luo Xuejiao Yang Wenmin Zhu Rongrong Zhu Changhong Zheng Yi Eve Sun Liming Cheng 2022Signal Transduction and Targeted Therapy2022,7,4:4

9A graphene rheostat for highly durable and stretchable strain sensor显示文摘Strain sensors for human health monitoring are of paramount importance in wearable medical diagnostics and personal health monitoring.Despite extensive studies,strain sensors with both high durability and stretchability are still desired,particularly with the stability for different environmental conditions.Here,we report a series of strain sensors possessing the graphene network with a high density of intermittent physical interconnections,which produces the relative resistance change by varying the overlap area between the neighboring graphene sheets under stretching and releasing,analogous to the slide rheostat working in electronics.Our in-situ transmission electron microscope observation reveals the full recoverability of the structure from large deformation upon unloading for ensuring the exceptional cycle stability of our material on monitoring full-range body movements.The stable response is also demonstrated over wide temperature range and frequency range,because the peculiar dynamic structure can be maintained through the self-adjustment to the thermal expansion of the bulk material.Based on the working mechanism of graphene“slide rheostat,”the sensing properties of the strain sensor are tailored by tuning the graphene network structure with different mass densities using different concentrations of graphene oxide dispersion,while the stretchability and sensitivity can be separately optimized for different application requirements.Jing Ren Wenjun Zhang Yubo Wang Yaxiong Wang Jun Zhou Liming Dai Ming Xu 2019InfoMat2019,1,3:4
10Exploring the friction and wear behaviors of Ag–Mo hybrid modified thermosetting polyimide composites at high tem-perature显示文摘Polyimide composites have been extensively used as motion components under extreme conditions for their thermal stability and special self-lubricating performance. In the present study, Ag–Mo hybrids as lubricant fillers were incorporated into thermosetting polyimide to prepare a new type of tribo-materials (TPI-1) at high temperature. Comprehensive investigations at different temperatures reveal that the newly developed TPI-1 exhibits a better reduction in friction and wear rate below 100 ℃, but all of them increase significantly when the bulk temperature exceeds 250℃. The wear mechanisms demonstrated that sandwich-like tribofilms with different layers were established at different temperatures, which was further verified by characterization of scanning electron microscope (SEM), Raman spectroscopy, and transmission electron microscope (TEM). Considering the high-performance TPI coupled with Ag–Mo hybrids, we anticipate that further exploration would provide guidance for designing TPI tribo-materials that would be used at high temperatures.Chunjian DUAN Ren HE Song LI Mingchao SHAO Rui YANG Liming TAO Chao WANG Ping YUAN Tingmei WANG Qihua WANG 2020Friction2020,8,5:3
11Toward High Carrier Mobility and Low Contact Resistance:Laser Cleaning of PMMA Residues on Graphene Surfaces显示文摘Poly(methyl methacrylate)(PMMA) is widely used for graphene transfer and device fabrication.However,it inevitably leaves a thin layer of polymer residues after acetone rinsing and leads to dramatic degradation of device performance.How to eliminate contamination and restore clean surfaces of graphene is still highly demanded.In this paper,we present a reliable and position-controllable method to remove the polymer residues on graphene films by laser exposure.Under proper laser conditions,PMMA residues can be substantially reduced without introducing defects to the underlying graphene.Furthermore,by applying this laser cleaning technique to the channel and contacts of graphene fieldeffect transistors(GFETs),higher carrier mobility as well as lower contact resistance can be realized.This work opens a way for probing intrinsic properties of contaminant-free graphene and fabricating high-performance GFETs with both clean channel and intimate graphene/metal contact.Yuehui Jia Xin Gong Pei Peng Zidong Wang Zhongzheng Tian Liming Ren Yunyi Fu Han Zhang 2016Nano-Micro Letters2016,8,4:2
12Fuzzy conditional proxy re-encryption显示文摘Weng et al.introduced the notion of conditional proxy re-encryption(C-PRE),whereby only the ciphertext satisfying one condition set by Alice can be re-encrypted by the proxy.To achieve more fine-grained delegation on the condition set,we introduce a new cryptographic primitive called fuzzy conditional proxy re-encryption(FC-PRE) in which we view conditions in C-PRE as a set of descriptive keywords.A FC-PRE scheme allows for a proxy with the re-encryption key for a conditional keyword set,W,to re-encrypt a ciphertext encrypted with a conditional keyword set,W,if and only if W and W are close to each other as measured by the 'set overlap' distance metric.Therefore,our system allows a certain amount of error-tolerance in the conditions.We formalize the FC-PRE security model by incorporating the advantages in previous C-PRE.Finally,we present an efficient construction of FC-PRE scheme,and prove its CCA-security under the wellstudied decisional bilinear Diffie-Hellman(DBDH) assumption in the random oracle model.FANG LiMing WANG JianDong GE ChunPeng REN YongJun 2013Science China(Information Sciences)2013,56,5:2
13Prediction of the coupled heat radiation and conduction parameters and boundary condition using the unscented Kalman filter显示文摘The boundary emissivity, thermal conductivity, and boundary time-varying heat flux in the participating media are retrieved in this work. In the forward model, the coupled radiation-conduction heat transfer in the participating medium is resolved by the finite volume method combined with discrete ordinates method. The inverse model utilizes the temperature signals at the appropriate position of the medium as the known information and uses the unscented Kalman filter(UKF) as an optimization tool to reconstruct the boundary emissivity, thermal conductivity, and boundary time-varying heat flux. It is found that when the emissivity, thermal conductivity, and boundary time-varying heat flux are reconstructed simultaneously, only the temperature information of two locations is required. The influence of the measurement noise, sampling interval, absorption coefficient,process noise covariance, measurement noise covariance on the accuracy and stability of the retrieval results is investigated in detail. All the reconstruction results indicate that the UKF technique is effective and robust for estimating the photothermal parameters and boundary condition of the radiation-conduction heat transfer problems.WEN Shuang QI Hong WANG YiFei REN YaTao WEI LinYang RUAN LiMing 2020Science China(Technological Sciences)2020,63,3:2

15Selected multiferroic perovskite oxides containing rare earth and transition metal elements显示文摘Multiferroic materials are currently the subject of intensive research worldwide, because of both their fundamental scientific problems and also possible technological applications. Among a number of candidates in the laboratories, compounds consisting of rare earth and transition metal perovskite oxides have very unusual structural and physical properties. In contrast to the so-called type I multiferroics, ferroelectricity may be induced by magnetic ordering or by applying external fields. In this review, the recent progress on the experimental and theoretical studies of some selected type II multiferroics is presented, with a focus on the perovskite oxides containing rare earth and transition metal elements. The rare earth orthoferrite crystals, rare earth titanate strained film, and rare earthbased superlattices are systematically reviewed to provide a broad overview on their promising electric, magnetic, and structural properties. The recent experimental advances in single-crystal growth by optical floating zone method are also presented. First-principles investigations, either supported by experimental results or awaiting for experimental verifications, are shown to offer useful guidance for the future applications of unconventional multiferroics.Shunbo Hu Lei Chen Yabei Wu Liming Yu Xinluo Zhao Shixun Cao Jincang Zhang Wei Ren 2014Chinese Science Bulletin2014,59,36:2
16Ultrasonic Welding of Magnesium–Titanium Dissimilar Metals:A Study on Thermo-mechanical Analyses of Welding Process by Experimentation and Finite Element Method显示文摘Ultrasonic welding is an effective ways to achieve a non-reactive/immiscible heterogeneous metal connection, such as the connection of magnesium alloy and titanium alloy. But the thermal mechanism of magnesium alloy/titanium alloy ultrasonic welding has not been defined clearly. In this paper, the experimental and the finite element analysis were adopted to study the thermal mechanism during welding. Through the test, the temperature variation law during the welding process is obtained, and the accuracy of the finite element model is verified. The microscopic analysis indicates that at the welding time of 0.5 s, the magnesium alloy in the center of the solder joint is partially melted and generates the liquid phase. Through the finite element analysis, the friction coefficient of the magnesium–titanium ultrasonic welding interface can be considered as an average constant value of 0.28. The maximum temperature at the interface can exceed 600 ℃ to reach the melting point temperature of the magnesium alloy. The plastic deformation begins after 0.35 s and occurs at the magnesium side at the center of the interface.Dewang Zhao Daxin Ren Kunmin Zhao Pan Sun Xinglin Guo Liming Liu 2019Chinese Journal of Mechanical Engineering2019,32,6:2
