1Development of fractures in soft rock surrounding a roadway and their control显示文摘As the excavation of roadway,new fractures will be formed and the pre-existing fractures extend with the redistribution of stress in surrounding rocks.Eventually,fracture zone and bed separation are formed in rocks because of the developed fractures.Therefore,mastering the fracture evolution of surrounding rocks is very important to maintain the stability of roadway.The surrounding rocks of main haulage roadway in a certain coal mine is so broken and loose that the supporting is very difficult.Based on comprehensive analysis of the engineering geological conditions,a sight instrument was used to observe the fractures of internal surrounding rocks.Four indices,i.e.,the width of fracture zone W,the number of fractures n,the width of fractures d and rock fracture designation RFD,are put forward to evaluate the fracture development.According to the evolution rules of the soft rock roadway from this paper,control principles by stages and by regions are presented through the research.At the same time,the best time of grouting reinforcement is determined on the basis of fracture saturation.Field practice shows that the roadway can satisfy normal production during service periods by suitable first support and grouting reinforcement.Li Xuehua Yao Qiangling Man Jiankang Chen Chaoqun He Lihui 2011Mining Science and Technology2011,21,4:12
2Investigation of dielectric barrier discharge plasma flow control显示文摘Effects of plasma flow control are researched on the basis of plasma exciting flow experiments and numerical simulations. Turbulent model is more effective than laminar model in plasma numerical simulation as results showed. Both plasma exciting effects of acceleration and flow separation suppression are investigated through experiments carried on the flat plate and the compressor cascades. The results demonstrate that boundary layer characteristic is modified by plasma exciting. Distributions of total pressure and velocity in the wake are improved notably for 20 m/s coming velocity and the effect of plasma can still be observed while velocity is increased to 50 m/s. For low velocity flow, plasma exciting is effective in flow separation suppression.NIE ChaoQun LI Gang ZHU JunQiang ZHANG Yi LI YuTong 2008Science China(Technological Sciences)2008,51,7:9
3Localization and characterization of the hypothetical protein CT440 in Chlamydia trachomatis-infected cells显示文摘The inclusion membrane proteins play potentially important roles in chlamydial biology and pathogenesis.Here we localized and characterized the hypothetical protein CT440 in Chlamydia trachomatis-infected cells.The open reading frame(ORF) encoding the CT440 protein from the C.trachomatis serovar D genome was cloned into the prokaryotic expression vector pGEX-6p and expressed as a glutathione-S-transferase(GST) fusion protein in E.coli XL1-Blue.The CT440 fusion protein was used to immunize mice to raise antigen-specific antibody.After verification by Western blot and immunofluorescence assay(IFA),the specific antibody was used to localize the endogenous CT440 protein and to detect its expression pattern in Chlamydia-infected cells.Cytosolic expression of CT440 in HeLa cells was also carried out to evaluate the effect of the CT440 protein on the subsequent chlamydial infection.The results showed that the hypothetical protein CT440 was localized in the C.trachomatis inclusion membrane,and was detectable 12 h after chlamydial infection.Expression of CT440 in the cytoplasm did not inhibit the subsequent chlamydial infection.In summary,we have identified a new inclusion membrane protein that may be an important candidate for understanding C.trachomatis pathogenesis.LI ZhongYu HUANG QiuLin SU ShengMei ZHOU Zhou CHEN ChaoQun ZHONG GuangMing WU YiMou 2011Science China(Life Sciences)2011,54,11:5
4Model study of relationship between local temperature and artificial heat release显示文摘In recent decades,it presents a more obvious temperature rise in urban area along with the global warming.City is generally the center of human society,so the study on urban temperature variation will be helpful to our city development planning that is to reduce urban warming.The study is also helpful to a more comprehensive understanding of the causes of climate warming,which could provide a theoretical support to the government to make more reasonable international energy policies.Local temperature rise has different mechanisms with the global warming:large quantities of artificial heat release from the energy consumption will stay in urban areas for a period of time,which will inevitably influence the short-term trend of the local temperature change.Based on that view,a structural thermodynamic model was established in this paper to investigate the effect of the artificial heat release on the urban local temperatures.In the model,the city environment was divided into Human,Local,Outer three blocks,and then the heat and temperatures of the blocks were analyzed based on the laws of thermodynamics.After that,the effect of artificial heat release in Human block on the local temperatures was clarified.The model shows that the artificial heat release has an approximately linearly promoting effect on the local temperature rise,and the more the heat release is,the stronger the effect is.In addition,a validation of that model was carried out based on some national statistical data.The data of temperatures and artificial heat release of some provincial capitals of China were analyzed with linear regression extrapolation method and Pearson correlation statistical method.The results show that in most capital cities,the temperature variations basically depend on the artificial heat release in a linear relationship,which usually becomes more apparent with the increase of the artificial heat release in both spatial and temporal dimensions.The conclusions of the statistics have good conformity with the model and the rationality of the model is verified.NIU Qiang NIE ChaoQun LIN Feng LI Ling JI LuCheng 2012Science China(Technological Sciences)2012,55,3:5
5Control of endwall secondary flow in a compressor cascade with dielectric barrier discharge plasma actuation显示文摘Three dielectric barrier discharge plasma actuators were mounted at the positions of 20%,40%and 60%of chord length on the endwall in a compressor cascade.The downstream flow field of the cascade has been measured with a mini five-hole pressure probe with and without the plasma actuation.The measured results show that the plasma actuation most effectively reduces total pressure loss and flow blockage when the actuators are operated simultaneously.As each of the actuators is operated independently,the actuator at the position of 20%of chord length most effectively reduces flow blockage, and the actuator at the position of 60%of chord length fairly reduces total pressure loss.However, negative pressure loss reduction occurs with the plasma actuator at the position of 40%of chord length.In brief,the plasma actuation placed on the endwall in the cascade apparently influences the endwall secondary flow,and the optimal locations and strength of actuation are critical for the control of endwall secondary flow in a compressor cascade with the plasma actuators.LI Gang XU YanJi LIN Bin ZHU JunQiang NIE ChaoQun MA HongWei WANG ZhaoFeng 2009Science China(Technological Sciences)2009,52,12:5
6Non-equilibrium Plasma Assisted Combustion of Low Heating Value Fuels显示文摘This paper describes the effects of non-equilibrium air plasma generated by a dielectric barrier discharge (DBD) on the combustion of low heating value fuels. The experimental results indicate that addition of a very small amount of energy to the air flow in the form of DBD significantly improves the flame stability. Moreover, main combustion characteristics such as flame propagation speed, combustion intensity and lean blow-off limits are also enhanced by the effect of plasma. Some active radicals such as excited O atom and excited N2 molecule are observed by spectrograph in the discharge area. Based on the results of numerical investigation we can conclude that these active radicals generated in discharge area can accelerate the production rate of active OH radical which plays a key role in the oxidation process of low heating value fuel, and thus the whole combustion process is accelerated.Hongbin Hu Quanbin Song Yanji Xu Gang Li Chaoqun Nie 2013Journal of Thermal Science2013,22,3:4
7Recent active thermal management technologies for the development of energy-optimized aerospace vehicles in China显示文摘Recently, the development of modern vehicles has brought about aggressive integration and miniaturization of on-board electrical and electronic devices. It will lead to exponential growth in both the overall waste heat and heat flux to be dissipated to maintain the devices within a safe temperature range. However, both the total heat sinks aboard and the cooling capacity of currently utilized thermal control strategy are severely limited, which threatens the lifetime of the on-board equipment and even the entire flight system and shrink the vehicle’s flight time and range. Facing these thermal challenges, the USA proposed the program of 'INVENT' to maximize utilities of the available heat sinks and enhance the cooling ability of thermal control strategies. Following the efforts done by the USA researchers, scientists in China fought their ways to develop thermal management technologies for Chinese advanced energy-optimized airplanes and spacecraft. This paper elaborates the available on-board heat sinks and aerospace thermal management systems using both active and passive technologies not confined to the technology in China. Subsequently, active thermal management technologies in China including fuel thermal management system, environment control system, non-fuel liquid cooling strategy are reviewed. At last, space thermal control technologies used in Chinese Space Station and Chang’e-3 and to be used in Chang’e-5 are introduced.Key issues to be solved are also identified, which could facilitate the development of aerospace thermal control techniques across the world.Jixiang WANG Yunze LI Xiangdong LIU Chaoqun SHEN Hongsheng ZHANG Kai XIONG 2021Chinese Journal of Aeronautics2021,34,2:4

9Manipulating dielectric property of polymer coatings toward highretention-rate lithium metal full batteries under harsh critical conditions显示文摘Lithium(Li)metal batteries(LMBs)can potentially deliver much higher energy density but remain plagued by uncontrollable Li plating with dendrite growth,unstable interfaces,and highly abundant excess Li(>50 mAh·cm^(-2)).Herein,different from the artificial layer or three-dimensional(3D)matrix host constructions,various dielectric polymers are initially well-comprehensively investigated from experimental characterizations to theoretical simulation to evaluate their functions in modulating Li ion distribution.As a proof of concept,a 3D interwoven high dielectric functional polymer(HDFP)nanofiber network with polar C-F dipole moments electrospun on copper(Cu)foil is designed,realizing uniform and controllable Li deposition capacity up to 5.0 mAh·cm^(-2),thereby enabling stable Li plating/stripping cycling over 1400 h at 1.0 mA·cm^(-2).More importantly,under the highcathode loading(~3.1 mAh·cm^(-2))and only 0.6×excess Li(N/P ratio of 1.6),the full cells retain capacity retention of 97.4%after 200 cycles at 3.36 mA·cm^(-2)and achieve high energy density(297.7 Wh·kg^(-1)at cell-level)under lean electrolyte conditions(15μL),much better than ever-reported literatures.Our work provides a new direction for designing high dielectric polymer coating toward high-retention-rate practical Li full batteries.Qi Kang Zechao Zhuang Yong Li Yinze Zuo Jian Wang Yijie Liu Chaoqun Shi Jie Chen Hongfei Li Pingkai Jiang Xingyi Huang 2023Nano Research2023,16,7:3
10Sex Differences in Diagnosis and Clinical Phenotypes of Chinese Children with Autism Spectrum Disorder显示文摘The aim of this study was to explore the differences between boys and girls in the diagnosis and clinical phenotypes of autism spectrum disorder(ASD) in China's mainland. Children diagnosed with ASD(n = 1064, 228 females) were retrospectively included in the analysis. All children were assessed using the Autism Diagnostic Interview-Revised(ADI-R) and Autism Diagnostic Observation Schedule(ADOS). The results showed that girls scored significantly higher in ADI-R socioemotional reciprocity than boys, and also scored lower in ADI-R and ADOS restricted and repetitive behaviors(RRBs). Meanwhile, the proportions of girls who satisfied the diagnostic cut-off scores in the ADI-R RRBs domain were lower than in boys(P \ 0.05). Our results indicated that girls with ASD show greater socio-emotional reciprocity than boys. Girls also tended to show fewer RRBs than boys, and the type of RRBs in girls differ from those in boys. The ADI-R was found to be less sensitive in girls, particularly for assessment in the RRBs domain.Shihuan Wang Hongzhu Deng Cong You Kaiyun Chen Jianying Li Chun Tang Chaoqun Ceng Yuanyuan Zou Xiaobing Zou 2017Neuroscience Bulletin2017,33,2:3
11Low Speed Axial Compressor Stall Margin Improvement by Unsteady Plasma Actuation显示文摘This research investigates the use of single dielectric barrier discharge(SDBD) actuators for energizing the tip leakage flow to suppress rotating stall inception and extend the stable operating range of a low speed axial compressor with a single rotor.The jet induced by the plasma actuator adds momentum to the flow in the tip region and has a significant impact on the tip-gap flow.Experiments are carried out on a low speed axial compressor with a single rotor.The static pressure is measured at both the rotor inlet and outlet.The flow coefficient and pressure rise coefficient are calculated.Then the characteristic line is acquired to show the overall performance of the compressor.With unsteady plasma actuation of 18kV and 60W the compressor stability range improvement is realized at rotor speed of 1500 r/min – 2400 r/min.LI Gang XU Yanji YANG Lingyuan DU Wei ZHU Junqiang NIE Chaoqun 2014Journal of Thermal Science2014,23,2:3
12Insulin-like growth factor 1-induced enolase 2 deacetylation by HDAC3 promotes metastasis of pancreatic cancer显示文摘Enolase 2(ENO2)is a key glycolytic enzyme in the metabolic process of glycolysis,but its potential function in pancreatic ductal adenocarcinoma(PDAC)is unclear.In this study,we observed a significant overexpression of ENO2 in PDAC tissues,and its expression was correlated with metastasis and poor prognosis in PDAC patients.K394 was identified as a major acetylation site in ENO2 that regulates its enzymatic activity,cell metabolism and PDAC progression.Knockdown of ENO2 suppressed tumor growth and liver metastasis in PDAC.Re-expression of wild-type(WT)ENO2,but not the K394 acetylation mimetic mutant,could reverse the decreased tumor malignancy.We further characterized histone deacetylase 3(HDAC3)and P300/CBP-associated factor(PCAF)as the potential deacetylase and acetyltransferase for ENO2,respectively.HDAC3-mediated deacetylation was shown to lead to ENO2 activation and enhancement of glycolysis.Importantly,insulin-like growth factor-1(IGF-1)was found to decrease K394 acetylation and stimulate ENO2 activity in a dose-and time-dependent manner.The PI3K/AKT/mTOR pathway facilitated the phosphorylation of HDAC3 on S424,which promoted K394 deacetylation and activation of ENO2.Linsitinib,an oral small-molecule inhibitor of IGF-1R,could inhibit IGF-1-induced ENO2 deacetylation by HDAC3 and the PI3K/AKT/mTOR pathway.Furthermore,linsitinib showed a different effect on the growth and metastasis of PDAC depending on the overexpression of WT versus K394-mutant ENO2.Our results reveal a novel mechanism by which acetylation negatively regulates ENO2 activity in the metastasis of PDAC by modulating glycolysis.Blockade of IGF-1-induced ENO2 deacetylation represents a promising strategy to prevent the development of PDAC.Yan Zheng Chao Wu Jimeng Yang Yue Zhao Huliang Jia Min Xue Da Xu Feng Yang Deliang Fu Chaoqun Wang Beiyuan Hu Ze Zhang Tianen Li Shican Yan Xuan Wang Peter J.Nelson Christiane Bruns Lunxiu Qin Qiongzhu Dong 2020Signal Transduction and Targeted Therapy2020,5,1:3
13Autonomous live working robot navigation with real-time detection and motion planning system on distribution line显示文摘In this study,an autonomous robot navigation system is designed for live working on distribution line.The developed system features a real-time detection and motion planning system,incorporating a manipulator capable of grasping power components.In order to accurately identify targets,the authors propose an object detection method based on the Larger Scale‘You Only Look Once’Version 4(LS-YOLOv4)algorithm for detecting the insulators and drop fuses.The LS-YOLOv4 extracts features of power components by Convolutional Neural Network(CNN),and then performs feature fusion.Then the authors develop a motion planning method based on the Node Control Optimal Rapidly Exploring Random Trees(NC-RRT*),which can drive the robot to realise the autonomous robot motion planning and obstacle avoidance.On the grasping function,the authors present a reliable Lightweight-based Convolutional Neural Network(L-CNN)grasping point detection method.Finally,the authors evaluate fully autonomous robotic system in both simulated and real-world experiments.The experimental results demonstrate that the proposed system can effectively identify the target and complete the grasping task in an efficient way.Notably,the proposed motion planning method can take into account both planning efficiency and accuracy to manipulation tasks.Haoning Zhao Chaoqun Wang Rui Guo Xuewen Rong Jiamin Guo Qixun Yang Lecheng Yang Yuliang Zhao Yibin Li 2022High Voltage2022,7,6:2
14Enhancing the power conversion efficiency of PCDTBT:PC_(71)BM polymer solar cells using a mixture of solvents显示文摘Organic polymer solar materials are shown to exhibit better solubility in mixed solvents than in pure ones,which affects the performance of their solar cells.In this article,poly[N-9-hepta-decanyl-2,7-carbazole-alt-5,5-(4.7-di-2-thienyI-2,l,3-benzothiadiazole)(PCDTBT0)and[6,6]-phenyl-C71-butyric acid methyl ester(PC_(71)BM)are used as active layer materials in solar cells.To optimize the performance of these active materials,the ratio of chloroform(CF)to chlorobenzene used as solvents to dissolve PCDTBT,and PC_(71)BM is varied,which is shown to affect power conversion efficiency(PCE).The solar cell that shows the best performance with a PCE as high as 6.82%is produced using a volume ratio of CF to chlorobenzene of1:1.Shaopeng Yang Ye Zhang Tao Jiang Xuefeng Sun Chaoqun Lu Guang Li Xiaowei Li Guangsheng Fu 2014Chinese Science Bulletin2014,59,3:2
15Growth of BeO Nanograins Synthesized by Polyacrylamide Gel Route显示文摘BeO nanoparticles were synthesized by polyacrylamide gel route.The effects of the processing parameters on the morphology and size of the synthesized BeO nanoparticles were investigated.The calcination temperature of the gel precursor containing beryllium sulfate was determined by thermogravimetry and differential scanning calorimetry(TG-DSC),which is around 690 C and 160 C lower than the general temperature.Xray diffractometry(XRD),transmission electron microscopy(TEM),and specific surface area measurements(BET) showed that the synthesized nanoparticles under 700 C were pure,globular and about ~5-20 nm with narrow distribution.Interestingly,the nanograins coalesced and grew under higher calcination temperatures and longer calcination time.The influence of calcination temperature on the morphology and growth behavior is greater than that of its duration.The activation energy for grain growth was estimated to be 24.53 kJ/mol,and the dominant growth mechanism was most likely to be related to the vapor transport in pore control mode and grain-rotation-induced grain coalescence(GRIGC) mechanism.Xiaofeng Wang Richu Wang Chaoqun Peng Tingting Li Bing Liu 2011Journal of Materials Science & Technology2011,27,2:2
16SRSF1 inhibits autophagy through regulating Bcl-x splicing and interacting with PIK3C3 in lung cancer显示文摘Alternative splicing is a critical process to generate protein diversity.However,whether and how alternative splicing regulates autophagy remains largely elusive.Here we systematically identify the splicing factor SRSF1 as an autophagy suppressor.Specifically,SRSF1 inhibits autophagosome formation by reducing the accumulation of LC3-ⅡI and numbers of autophagosomes in different cell lines.Mechanistically,SRSF1 promotes the splicing of the long isoform of Bcl-x that interacts with Beclinl,thereby dissociating the Beclin1-PIK3C3 complex.In addition,SRSF1 also directly interacts with PIK3C3 to disrupt the interaction between Beclinl and PIK3C3.Consequently,the decrease of SRSF1 stabilizes the Beclinl and PIK3C3 complex and activates autophagy.Interestingly,SRSF1 can be degraded by starvation-and oxidative stresses-induced autophagy through interacting with LC3-Ⅱ,whereas reduced SRSF1 further promotes autophagy.This positive feedback is critical to inhibiting Gefitinib-resistant cancer cell progression both in vitro and in vivo.Consistently,the expression level of SRSF1 is inversely correlated to LC3 level in clinical cancer samples.Our study not only provides mechanistic insights of alternative splicing in autophagy regulation but also discovers a new regulatory role of SRSF1 in tumorigenesis,thereby offering a novel avenue for potential cancer therapeutics.Yuesheng Lv Wenjing Zhang Jinyao Zhao Bing Sun Yangfan Qi Haoyu Ji Chaoqun Chen Jinrui Zhang Junxiu Sheng Taishu Wang Daniel Dominguez Han Liu Quentin Liu Songshu Meng Xiaoling Li Yang Wang 2021Signal Transduction and Targeted Therapy2021,6,4:2
17Raindrop energy-powered autonomous wireless hyetometer based on liquid-solid contact electrification显示文摘Triboelectric nanogenerators(TENGs)can directly harvest energy via solid-liquid interface contact electrification,making them very suitable for harvesting raindrop energy and as active rainfall sensors.This technology is promising for realizing a fully self-powered system for autonomous rainfall monitoring combined with energy harvesting/sensing.Here,we report a raindrop energy-powered autonomous rainfall monitoring and wireless transmission system(R-RMS),in which a raindrop-TENG(R-TENG)array simultaneously serves as a raindrop energy harvester and rainfall sensor.At a rainfall intensity of 71 mm/min,the R-TENG array can generate an average short-circuit current,open-circuit voltage,and maximum output power of 15 pA,1800 V,and 325 pW,respectively.The collected energy can be adjusted to act as a stable 2.5 V direct-current source for the whole system by a power management circuit.Meanwhile,the R-TENG array acts as a rainfall sensor,in which the output signal can be monitored and the measured data are wirelessly transmitted.Linder a rainfall intensity of 71 mm/min,the R-RMS can be continuously powered and autonomously transmit rainfall data once every 4 min.This work has paved the way for raindrop energy-powered wireless hyetometers,which have exhibited broad prospects in unattended weather monitoring,field surveys,and the Internet of Things.Chaoqun Xu Xianpeng Fu Chengyu Li Guoxu Liu Yuyu Gao Youchao Qi Tianzhao Bu Yuanfen Chen Zhong Lin Wang Chi Zhang 2022Microsystems & Nanoengineering2022,8,2:2
18Tea stain-inspired solar energy harvesting polyphenolic nanocoatings with tunable absorption spectra显示文摘Discovery and development of new sustainable photothermal materials with tunable light absorption spectra play a key role in solar energy harvesting and conversion.One possible solution to this quest is to check nature as a source of matters or inspiration.Inspired by the formation of tea stains,a unique class of dark stain materials generated by the interfacial reaction between tea polyphenols and metal substance,we reported the facile preparation and screening of a series of photothermal nanocoating layers via the metal ion(i.e.C u(ll)>Fe(lll),Ni(ll),Zn(ll))promoted in situ polymerization of typical phenolic moieties of tea polyphenols(i.e.,catechol and pyrogallol).It was found that those resulting metal-polyphenolic nanocoatings showed various promising features,such as high blackness and strong adhesion,excellent and tunable light absorption properties,good hydrophilicity and long-term stability.We further fabricated the photothermal composite devices by/n s/'fty formation of meta卜polyphenolic nanocoatings on pristine silks for solar desalination,which demonstrated promising durable evaporation behaviors with excellent evaporation rates and steam generation efficiencies.We believe that this work could provide more opportunities towards new types of bio-inspired and sustainable photothermal nanomaterials for solar energy harvesting applications such as water desalination.Lu Yang Yuan Zou Wei Xia Haotian Li Xinyu He Yi Zhou Xianhu Liu Chaoqun Zhang Yiwen Li 2021Nano Research2021,14,4:2
