1Surface Exciton-Plasmon Polariton Enhanced Light Emission via Integration of Single Semiconductor Nanowires with Metal Nanostructures显示文摘The light emission enhancement behavior from single ZnO nanowires integrated with metallic contacts is investigated by micro-photoluminescence measurements.Apart from surface plasmon polaritons at the air/metal interface,the emission of a single ZnO nanowire can be coupled into guided modes of surface exciton-plasmon polaritons(SEPPs).The out-coupling avenues of SEPP guided modes are modeled in the presence of nanostructures,such as corrugation and gratings,on the metal surface.The guided modes of SEPPs in metal-contacted ZnO nanowires are calculated using the effective index method.The enhanced light emission from single semiconductor nanowires shows promise for use in highly efficient nano-emitters and nano-lasers,as well as macroscopic solid state light sources with very high efficiency.Xuejin Zhang Pengwei Wang Xinzheng Zhang Jun Xu Yongyuan Zhu Dapeng Yu 2009Nano Research2009,2,1:2

4Integrated tool for microsatellite isolation and validation from the reference genome and their application in the study of breeding turnover in an endangered avian population显示文摘Accurate individual identification is required to estimate survival rates in avian populations.For endangered species,non-invasive methods of obtaining individual identification,such as using molted feathers as a source of DNA for microsatellite markers,are preferred because of less disturbance,easy sample preparation and high efficiency.With the availability of many avian genomes,a few pipelines isolating genome-wide microsatellites have been published,but it is still a challenge to isolate microsatellites from the reference genome efficiently.Here,we have developed an integrated tool comprising a bioinformatic pipeline and experimental procedures for microsatellite isolation and validation based on the reference genome.We have identified over 95000 microsatellite loci and established a system comprising 10 highly polymorphic markers(PIC value:0.49–0.93,mean:0.79)for an endangered species,saker falcon(Falco cherrug).These markers(except 1)were successfully amplified in 126 molted feathers,exhibiting high amplification success rates(83.9–99.7%),high quality index(0.90–0.97)and low allelic dropout rates(1–9.5%).To further assess the efficiency of this marker system in a population study,we identified individual sakers using these molted feathers(adult)and 146 plucked feathers(offspring).The use of parent and offspring samples enabled us to infer the genotype of missing samples(N=28),and all adult genotypes were used to ascertain that breeding turnover is a useful proxy for survival estimation in sakers.Our study presents a cost-effective tool for microsatellite isolation based on publicly available reference genomes and demonstrates the power of this tool in estimating key parameters of avian population dynamics.Xian HOU Pengwei XU Zhenzhen LIN Josephine D’URBAN-JACKSON AndrewDIXON Batbayar BOLD Jiliang XU Xiangjiang ZHAN 2018Integrative Zoology2018,13,5:1
5Analysis of lithofacies and evaluation of effective reservoirs of member 2 of Xujiahe Formation in the Xinchang area in Western Sichuan显示文摘In the Xinchang area in western Sichuan Basin,a total of 121.12 billion cubic meters of proved reserves of natural gas are discovered in Member 2 of Xujiahe Formation,but only 7.739 billion cubic meters of proved reserves of natural gas are produced.The main reason is that sandstones in Member 2 of Xujiahe Formation in the Xinchang area are generally tight,with strong heterogeneity,only intervals with relatively good physical properties have a certain production capacity;therefore,it is very necessary and important to evaluate effective reservoirs in Member 2 of Xujiahe Formation.Through analysis of cores,with consideration of color,sedimentary texture and grain size,lithofacies of Member 2 of Xujiahe Formation in the Xinchang area can be divided into 12 types.According to data of physical properties and thin section analysis,it can be concluded that the favorable lithofacies in the upper submember of Member 2 of Xujiahe Formation are the massive medium-coarse sandstone,the medium-coarse sandstone with cross bedding,and the medium-coarse sandstone with carbonaceous fragments.On the basis of electrical characteristics,well-logging interpretation standards for favorable lithofacies are established,in addition,favorable lithofacies and effective reservoir in the Xinchang area are determined,and distribution of favorable lithofacies(effective reservoir)is identified,which lay a solid foundation for next deployment of appraisal well and development of effective reserves.Yanqing Huang Zhongqun Liu Pengwei Li Junlong Liu Changzhen Liao Shilin Xu 2020Petroleum Research2020,5,3:1
6Differentiating Malicious and Benign Android App Operations Using Second-Step Behavior Features显示文摘Security-sensitive operations in Android applications (apps for short) can either be benign or malicious. In this work, we introduce an approach of static program analysis that extracts “second-step behavior features”,i.e., what was triggered by the security-sensitive operation, to assist app analysis in differentiating between malicious and benign operations. Firstly, we summarized the characteristics of malicious operations, such as spontaneity, independence, stealthiness and continuity, which can be used to classify the malicious operations and benign ones. Secondly, according to these characteristics, Second step behavior features (SSBFs for short) have been presented, including structural features and semantic features. Thirdly, an analysis prototype named SSdroid has been implemented to automatically extract SSBFs of security-sensitive operations. Finally, experiments on 9285 operations from both benign and malicious apps show that SSBFs are effective and usefulness. Our evaluation results suggest that the second-step behavior can greatly assist in Android malware detection.LI Pengwei FU Jianming XU Chao CHENG Binlin ZHANG Huanguo 2019Chinese Journal of Electronics2019,28,5:1

9Protocatechuic acid and quercetin attenuate ETEC-caused IPEC-1 cell inflammation and injury associated with inhibition of necroptosis and pyroptosis signaling pathways显示文摘Background:Necroptosis and pyroptosis are newly identified forms of programmed cell death,which play a vital role in development of many gastrointestinal disorders.Although plant polyphenols have been reported to protect intestinal health,it is still unclear whether there is a beneficial role of plant polyphenols in modulating necroptosis and pyroptosis in intestinal porcine epithelial cell line(IPEC-1)infected with enterotoxigenic Escherichia coli(ETEC)K88.This research was conducted to explore whether plant polyphenols including protocatechuic acid(PCA)and quercetin(Que),attenuated inflammation and injury of IPEC-1 caused by ETEC K88 through regulating necroptosis and pyroptosis signaling pathways.Methods:IPEC-1 cells were treated with PCA(40μmol/L)or Que(10μmol/L)in the presence or absence of ETEC K88.Results:PCA and Que decreased ETEC K88 adhesion and endotoxin level(P<0.05)in cell supernatant.PCA and Que increased cell number(P<0.001)and decreased lactate dehydrogenases(LDH)activity(P<0.05)in cell supernatant after ETEC infection.PCA and Que improved transepithelial electrical resistance(TEER)(P<0.001)and reduced fluorescein isothiocyanate-labeled dextran(FD4)flux(P<0.001),and enhanced membrane protein abundance of occludin,claudin-1 and ZO-1(P<0.05),and rescued distribution of these tight junction proteins(P<0.05)after ETEC infection.PCA and Que also declined cell necrosis ratio(P<0.05).PCA and Que reduced mRNA abundance and concentration of tumor necrosis factor-α(TNF-α),interleukin(IL)-6 and IL-8(P<0.001),and down-regulated gene expression of toll-like receptors 4(TLR4)and its downstream signals(P<0.001)after ETEC infection.PCA and Que down-regulated protein abundance of total receptor interacting protein kinase 1(t-RIP1),phosphorylated-RIP1(p-RIP1),p-RIP1/t-RIP1,t-RIP3,p-RIP3,mixed lineage kinase domain-like protein(MLKL),p-MLKL,dynamin-related protein 1(DRP1),phosphoglycerate mutase 5(PGAM5)and high mobility group box 1(HMGB1)(P<0.05)after ETEC infection.Moreover,PCA and Que reduced protein abundance of nod-like receptor protein 3(NLRP3),nod-like receptors family CARD domain-containing protein 4(NLRC4),apoptosis-associated speck-like protein containing a CARD(ASC),gasdermin D(GSDMD)and caspase-1(P<0.05)after ETEC infection.Conclusions:In general,our data suggest that PCA and Que are capable of attenuating ETEC-caused intestinal inflammation and damage via inhibiting necroptosis and pyroptosis signaling pathways.Kan Xiao Mohan Zhou Qingqing Lv Pengwei He Xu Qin Dan Wang Jiangchao Zhao Yulan Liu 2023Journal of Animal Science and Biotechnology2023,14,4:0
10Feasibility and physics potential of detecting ^(8)B solar neutrinos at JUNO显示文摘The Jiangmen Underground Neutrino Observatory(JUNO)features a 20 kt multi-purpose underground liquid scintillator sphere as its main detector.Some of JUNO's features make it an excellent location for^8B solar neutrino measurements,such as its low-energy threshold,high energy resolution compared with water Cherenkov detectors,and much larger target mass compared with previous liquid scintillator detectors.In this paper,we present a comprehensive assessment of JUNO's potential for detecting^8B solar neutrinos via the neutrino-electron elastic scattering process.A reduced 2 MeV threshold for the recoil electron energy is found to be achievable,assuming that the intrinsic radioactive background^(238)U and^(232)Th in the liquid scintillator can be controlled to 10^(-17)g/g.With ten years of data acquisition,approximately 60,000 signal and 30,000 background events are expected.This large sample will enable an examination of the distortion of the recoil electron spectrum that is dominated by the neutrino flavor transformation in the dense solar matter,which will shed new light on the inconsistency between the measured electron spectra and the predictions of the standard three-flavor neutrino oscillation framework.IfDelta m^(2)_(21)=4.8times10^(-5);(7.5times10^(-5))eV^(2),JUNO can provide evidence of neutrino oscillation in the Earth at approximately the 3sigma(2sigma)level by measuring the non-zero signal rate variation with respect to the solar zenith angle.Moreover,JUNO can simultaneously measureDelta m^2_(21)using^8B solar neutrinos to a precision of 20% or better,depending on the central value,and to sub-percent precision using reactor antineutrinos.A comparison of these two measurements from the same detector will help understand the current mild inconsistency between the value of Delta m^2_(21)reported by solar neutrino experiments and the KamLAND experiment.Angel Abusleme Thomas Adam Shakeel Ahmad Sebastiano Aiello Muhammad Akram Nawab Ali Fengpeng An Guangpeng An Qi An Giuseppe Andronico Nikolay Anfimov Vito Antonelli Tatiana Antoshkina Burin

11Cutting the Cake of the Emission Cap in the Peer-to-peer Multi-energy Sharing Market显示文摘With the development of communication technology and distributed energy resources,trading of carbon emission rights and peer-to-peer energy transactions have become popular research directions on the end-user side.Therefore,a cap-andtrade emission framework with peer-to-peer energy trading is employed in this paper.The emission cap decomposition problem is solved under the circumstances of a multi-energy peer-topeer energy trading market.First,the multi-energy system is introduced in the peer-to-peer energy sharing model.The interaction between the prosumers and the system operator is defined.Then,the total emission cap,set by the operator,is modeled as a constraint.The decomposition of the emission cap is modeled as a cake-cutting game.Finally,the existence and uniqueness of the cake-cutting solution is proven by modeling the game to an equivalent monotone variational inequality problem.The complementary characteristics of multi energy in the market can ensure the utility of prosumers while reducing the total cap.Yuanxing Xia Qingshan Xu Siyu Tao Yixing Ding Jicheng Fang Pengwei Du 2023CSEE Journal of Power and Energy Systems2023,9,2:0
12Visualizing Macrophage Phenotypes and Polarization in Diseases:From Biomarkers to Molecular Probes显示文摘Macrophage is a kind of immune cell and performs multiple functions including pathogen phagocytosis,antigen presentation and tissue remodeling.To fulfll their functionally distinct roles,macrophages undergo polarization towards a spectrum of phenotypes,particularly the classically activated(M1)and alternatively activated(M2)subtypes.However,the binary M1/M2 phenotype fails to capture the complexity of macrophages subpopulations in vivo.Hence,it is crucial to employ spatiotemporal imaging techniques to visualize macrophage phenotypes and polarization,enabling the monitoring of disease progression and assessment of therapeutic responses to drug candidates.This review begins by discussing the origin,function and diversity of macrophage under physiological and pathological conditions.Subsequently,we summarize the identifed macrophage phenotypes and their specifc biomarkers.In addition,we present the imaging probes locating the lesions by visualizing macrophages with specifc phenotype in vivo.Finally,we discuss the challenges and prospects associated with monitoring immune microenvironment and disease progression through imaging of macrophage phenotypes.Dan Ni Heqing Zhou Pengwei Wang Fulin Xu Cong Li 2023Phenomics2023,3,6:0
13Progress,challenges,and prospects of spent lithium-ion batteries recycling:A review显示文摘The recycling and reutilization of spent lithium-ion batteries(LIBs)have become an important measure to alleviate problems like resource scarcity and environmental pollution.Although some progress has been made,battery recycling technology still faces challenges in terms of efficiency,effectiveness and environmental sustainability.This review aims to systematically review and analyze the current status of spent LIB recycling,and conduct a detailed comparison and evaluation of different recycling processes.In addition,this review introduces emerging recycling techniques,including deep eutectic solvents,molten salt roasting,and direct regeneration,with the intent of enhancing recycling efficiency and diminishing environmental repercussions.Furthermore,to increase the added value of recycled materials,this review proposes the concept of upgrading recycled materials into high value-added functional materials,such as catalysts,adsorbents,and graphene.Through life cycle assessment,the paper also explores the economic and environmental impacts of current battery recycling and highlights the importance that future recycling technologies should achieve a balance between recycling efficiency,economics and environmental benefits.Finally,this review outlines the opportunities and challenges of recycling key materials for next-generation batteries,and proposes relevant policy recommendations to promote the green and sustainable development of batteries,circular economy,and ecological civilization.Pengwei Li Shaohua Luo Lin Zhang Qiuyue Liu Yikai Wang Yicheng Lin Can Xu Jia Guo Peam Cheali Xiaoning Xia 2024Journal of Energy Chemistry2024,89,2:0
14Isolation and comparative proteomic analysis of mitochondria from the pulp of ripening citrus fruit显示文摘Mitochondria are crucial for the production of primary and secondary metabolites,which largely determine the quality of fruit.However,a method for isolating high-quality mitochondria is currently not available in citrus fruit,preventing high-throughput characterization of mitochondrial functions.Here,based on differential and discontinuous Percoll density gradient centrifugation,we devised a universal protocol for isolating mitochondria from the pulp of four major citrus species,including satsuma mandarin,ponkan mandarin,sweet orange,and pummelo.Western blot analysis and microscopy confirmed the high purity and intactness of the isolated mitochondria.By using this protocol coupled with a label-free proteomic approach,a total of 3353 nonredundant proteins were identified.Comparison of the four mitochondrial proteomes revealed that the proteins commonly detected in all proteomes participate in several typical metabolic pathways(such as tricarboxylic acid cycle,pyruvate metabolism,and oxidative phosphorylation)and pathways closely related to fruit quality(such asγ-aminobutyric acid(GABA)shunt,ascorbate metabolism,and biosynthesis of secondary metabolites).In addition,differentially abundant proteins(DAPs)between different types of species were also identified;these were found to be mainly involved in fatty acid and amino acid metabolism and were further confirmed to be localized to the mitochondria by subcellular localization analysis.In summary,the proposed protocol for the isolation of highly pure mitochondria from different citrus fruits may be used to obtain high-coverage mitochondrial proteomes,which can help to establish the association between mitochondrial metabolism and fruit storability or quality characteristics of different species and lay the foundation for discovering novel functions of mitochondria in plants.Xin Li Yingfang Chai Hongbin Yang Zhen Tian Chengyang Li Rangwei Xu Chunmei Shi Feng Zhu Yunliu Zeng Xiuxin Deng Pengwei Wang Yunjiang Cheng 2021Horticulture Research2021,8,1:0
15A robust Janus bilayer with tailored ionic conductivity and interface stability for stable Li metal anodes显示文摘The formation and growth of Li-dendrites caused by inhomogeneous Li deposition severely hinder the commercial applications of Li metal batteries due to the consequence of short-circuiting.Herein,we propose a Janus bilayer composed of black phosphorus(BP)and graphene oxide(GO)as an artificial interface with chemical/mechanical stability and well-regulated Li-ion flux distribution for Li metal anode protection.Owing to the synergy between the fast Li-ion transport of BP in the inner layer and the high mechanical and chemical stability of GO in the outer layer,the GO/BP with good electrolyte wettability acts as a Li-ion regulator that can induce homogeneous growth of Li to suppress the Li dendrites growth.Accordingly,long-term stability(500 h at 1 mA cm^(-2))with a low overpotential of 30 mV is achieved in the symmetric cell with GO/BP-Li anode.Furthermore,the Li–S cell with GO/BP-Li exhibits enhanced cycling performance with a high capacity retention rate of 76.2%over 500 cycles at 1 C.Guodong Zhang Pengwei Li Kai Chen Hongfei Zheng Wei He Liangping Xiao Xingyun Li Qingchi Xu Jian Weng Jun Xu 2022Journal of Energy Chemistry2022,31,11:0
16Adhesion and corrosion resistance of polycaprolactone coating on NiTi alloy surface after alkali heat pretreatment显示文摘Selective laser melting of nickel-titanium alloy(SLM-NiTi)can precisely control the size of the sample molding structure and has attracted extensive attention due to its special superelasticity and shape memory effect.However,the biological inertness and poor corrosion resistance of SLM-NiTi alloy limit their wide application as biomedical implant materials.In this study,polycaprolactone(PCL)coating was prepared on SLM-NiTi alloy by dipping and pulling method,and the effects of alkali heat pretreatment on the morphology,adhesion,corrosion resistance,long-term stability and biomineralisation of the PCL coatings were investigated.The results showed that PCL coating can substan-tially improve the performance of SLM-NiTi alloy,and the PCL coating after alkali heat pretreatment has higher adhesion(increased from 1,747 to 2,498 mN)and lower corrosion current density(reduced by about an order of magnitude compared to PCL coating alone).In addition,the necessary stability,biomineralisation and biocompatibility ability of coatings were also further improved.Therefore,the alkali heat pretreated PCL-coated SLM-NiTi alloy has good application prospects in implants due to its superior properties.Zhihui Zhang Yanan Yang Yunting Guo Pengwei Sha Zezhou Xu Zhenglei Yu Jiashun Si Zhengao Zhang Jia Guo Yifan Chen 2022Biosurface and Biotribology2022,8,4:0
17Joint observation of the concentric gravity wave event on the Tibetan Plateau显示文摘A concentric gravity wave event was captured by a photographer in NagarzêCounty(90.28°N,28.33°E)between 02:00 and 04:00(local time)on May 11,2019.This concentric gravity wave event was also observed by the Suomi National Polar-orbiting Partnership satellite and the all-sky airglow imager at Yangbajing station(90.5°E,30.1°N).The temporal and spatial information on gravity waves from the photographs provided a rare opportunity to study the propagation of gravity waves over the Tibetan Plateau.According to wind and temperature data from the MERRA-2 reanalysis(Modern-Era Retrospective analysis for Research and Applications,Version 2)and empirical models(NRLMSISE-00[Naval Research Laboratory Mass Spectrometer and Incoherent Scatter Radar Exosphere]and HWM[horizontal wind model]),we inversely derived the propagation trajectory from the observed wave pattern to the source region by using the ray-tracing method.The source of the concentric gravity wave was identified as deep convection in Bangladesh(90.6°E,25.0°N).The maximum background wind speed in the propagation direction(31.05 m/s)was less than the phase speed of 53 m/s,which is consistent with the wind-filtering theory.Chang Lai PengWei Li JiYao Xu Wei Yuan Jia Yue Xiao Liu Kogure Masaru LiLi Qian 2022Earth and Planetary Physics2022,6,3:0
