| 1 | Coupled modeling and analysis of radiometer effect and residual gas damping on proof mass in purely gravitational orbit显示文摘Spacecrafts free of all but gravitational forces are important in precision navigation,gravity field measurement and basic scientific research.The Inner-formation Flying System,one kind of spacecrafts free of all but gravitational forces,is used for gravitational field measurement with high precision.Restraining the interfering factors on the inner-satellite is one of the keys to gravitational field measurement.Radiometer effect and residual gas damping are both interfering forces on the inner-satellite caused by gas molecules.By analyzing the mechanism of the two forces,a coupled model for radiometer effect and residual gas damping was established,which contained the coupling term and reflected the actual force of gas molecules on the inner-satellite.The simulation results showed the coupling property of radiometer effect and residual gas damping:The actual force of gas molecules is directly proportional to the average pressure in the cavity and the largest cross-sectional area of the inner-satellite,but is inversely proportional to the square root of the average temperature in the cavity. | LIU HongWei WANG ZhaoKui ZHANG YuLin | 2011 | Science China(Technological Sciences)2011,54,4: | 8 |

| 3 | Analysis of residual gas disturbance on the inner satellite of Inner Formation Flying System显示文摘The Inner Formation Flying System(IFFS) consisting of an outer satellite and an inner satellite which is a sphere proof mass freely flying in the shield cavity can construct a pure gravity orbit to precisely detect the earth gravity field.The residual gas in the cavity is a significant disturbance source due to the temperature inhomogeneity and relative motion of the inner satellite.The expressions of the disturbance forces were derived based on the property of rarefied gas,including the radiometer effect and the damping force.According to the current design of IFFS,heat transfer analysis of the cavity and the inner satellite was carried out,and the surface temperature distribution of the cavity and the inner satellite was given.The relative motion of the inner satellite was obtained from the formation control simulation of IFFS.Then the residual gas disturbance was calculated.The disturbance acceleration acting on the inner satellite due to the radiometer effect was on the order of 10-11 ms-2 and the damping acceleration was on the order of 10-15 m s-2. | GU ZhenFeng WANG ZhaoKui ZHANG YuLin | 2012 | Science China(Technological Sciences)2012,55,9: | 1 |

| 9 | Engineering biocompatible TeSex nano-alloys as a versatile theranostic nanoplatform显示文摘Photothermal nanotheranostics, especially in the near infrared II(NIR-II) region, exhibits a great potential in precision and personalized medicine, owing to high tissue penetration of NIR-II light.NIR-II-photothermal nanoplatforms with high biocompatibility as well as high photothermal effect are urgently needed but rarely reported so far. Te nanomaterials possess high absorbance to NIR-II light but also exhibit high cytotoxicity, impeding their biomedical applications. In this work, the controllable incorporation of biocompatible Se into the lattice of Te nanostructures is proposed to intrinsically tune their inherent cytotoxicity and enhance their biocompatibility, developing TeSe_(x) nano-alloys as a new kind of theranostic nanoplatform. We have uncovered that the cytotoxicity of Te nanomaterials primarily derives from irreversible oxidation stress and intracellular imbalance of organization and energy, and can be eliminated by incorporating a moderate proportion of Se(x = 0.43). We have also discovered that the as-prepared TeSe_(x) nano-alloys have extraordinarily high NIR-II-photothermal conversion efficiency(77.2%),^(64)Cu coordination and computed tomography contrast capabilities, enabling high-efficacy multimodal photothermal/photoacoustic/positron emission tomography/computed tomography imaging-guided NIR-II-photothermal therapy of cancer. The proposed nano-alloying strategy provides a new route to improve the biocompatibility of biomedical nanoplatforms and endow them with versatile theranostic functions. | Xiang Ling Zhaokui Jin Qi Jiang Xiaotao Wang Bin Wei Zhongchang Wang Yangsen Xu Tianye Cao Jonathan W.Engle Weibo Cai Chenliang Su Qianjun He | 2021 | National Science Review2021,8,6: | 0 |

| 11 | Self-organizing strategy design and validation forintegrated air-ground detection swarm显示文摘A self-organized integrated air-ground detection swarm is tentatively applied to achieve reentry vehicle landing detection,such as searching and rescuing a manned spaceship. The detection swarm consists of multiple unmanned aerial vehicles(UAVs)and unmanned ground vehicles(UGVs). The UAVs can access a detected object quickly for high mobility, while the UGVs can comprehensively investigate the object due to the variety of carried equipment. In addition, the integrated air-ground detection swarm is capable of detecting from the ground and the air simultaneously. To accomplish the coordination of the UGVs and UAVs, they are all regarded as individuals of the artificial swarm.Those individuals make control decisions independently of others based on the self-organizing strategy. The overall requirements for the detection swarm are analyzed, and the theoretical model of the self-organizing strategy based on a combined individual and environmental virtual function is established. The numerical investigation proves that the self-organizing strategy is suitable and scalable to control the detection swarm. To further inspect the engineering reliability, an experiment set is established in laboratory,and the experimental demonstration shows that the self-organizing strategy drives the detection swarm forming a close range and multiangular surveillance configuration of a landing spot. | Meiyan An Zhaokui Wang Yulin Zhang | 2016 | Journal of Systems Engineering and Electronics2016,27,5: | 0 |
| 12 | SPATIOTEMPORAL VARIATION OF WATER QUALITY AND ALGAL BIOMASS IN ERHAI LAKE AND ITS ENVIRONMENTAL MANAGEMENT IMPLICATIONS显示文摘Elucidating the spatiotemporal pattern of water quality and algal biomass is crucial for accurately tracing pollution sources and reducing the risk of algal blooms in lake systems.This study analyzed the spatiotemporal variability of water quality and algal biomass in Erhai Lake from 1994 to 2021 using water quality index(WQi),Mann-Kendall test and Sen's slope combined methods.The potential causes of water quality deterioration and algal biomass dynamics were also elucidated.The results showed that the historical changes in the water environment of Erhai Lake mainly had three stages:satisfactory(1994-2001),deteriorating(2002-2010)and improving(2011-2021).The changes in water quality and algal biomass were primarily affected by total nitrogen,total phosphorus and chemical oxygen demand in different stages.The water environment of Erhai Lake is currently improving significantly,starting in the southern area that is furthest from the sources of agricultural pollution,especially in summer and autumn.This is attributed to the implementation of control measures resulting in lower pollutant loads at particular times and places.Therefore,it is necessary to continue to promote standardized livestock farming,to strengthen rural wastewater collection and to investigate measures such as the interruption of the endogenous cycle. | Xiaofei LIU Yue WU Zhaokui NI Shengrui WANG | 2023 | Frontiers of Agricultural Science and Engineering2023,10,4: | 0 |
| 13 | Effect of Rhei Radix et Rhizoma and Eupolyphaga Steleophaga on liver protection mechanism based on pharmacokinetics and metabonomics显示文摘Objective:Based on metabonomics technology of high-performance liquid chromatography-mass spectrometry(HPLC-MS/MS)and hydrogen nuclear magnetic resonance spectroscopy(^(1)H NMR),the pharmacokinetic characteristics and therapeutic mechanism of Rhei Radix et Rhizoma(RhRR,Dahuang in Chinese),Eupolyphaga Steleophaga(EuS,Tubiechong in Chinese)combined with RhRR acting on acute liver injury were explored.Methods:Models of acute liver injury were established,and the pharmacokinetic methods of five components of RhRR-EuS in rats were found by HPLC-MS/MS.The liver tissues of different groups of mice were analyzed by ^(1)H NMR spectroscopy combined with multivariate statistical analysis to investigate the metabolomics of RhRR-EuS and RhRR.Results:Pharmacokinetic results showed there were different levels of bimodal phenomenon in different groups,and the absorption of free anthraquinone in RhRR increased after compatibility with EuS.In addition,the pathological state of acute liver injury in rats can selectively promote the absorption of emodin,chrysophanol,physcion and aloe emodin.Through 15 differential metabolites in the liver tissue of acute liver injury mice,it was revealed that RhRR-EuS and RhRR could protect the liver injury by regulating the metabolism of glutamine and glutamic acid,alanine,aspartic acid and glutamic acid,and phosphoinositide.However,the regulation of RhRR was weaker than that of RhRR-EuS.Conclusion:For the first time,we studied the pharmacokinetics and metabolomics differences of RhRREuS and RhRR in rats and mice with acute liver injury,in order to provide theoretical reference for clinical treatment of liver disease by DHZCP. | Gang Feng Jianli Bi Wenfang Jin Qi Wang Zhaokui Dan Baolei Fan | 2024 | Chinese Herbal Medicines2024,16,1: | 0 |
| 14 | A nanoconcrete welding strategy for constructing high-performance wound dressing显示文摘Engineering biomaterials to meet specific biomedical applications raises high requirements of mechanical performances,and simultaneous strengthening and toughening of polymer are frequently necessary but very challenging in many cases.In this work,we propose a new concept of nanoconcrete welding polymer chains,where mesoporous CaCO3(mCaCO_(3))nanoconcretes which are composed of amorphous and nanocrystalline phases are developed to powerfully weld polymer chains through siphoning-induced occlusion,hydration-driven crystallization and dehydration-driven compression of nanoconcretes.The mCaCO_(3) nanoconcrete welding technology is verified to be able to remarkably augment strength,toughness and anti-fatigue performances of a model polymer poly(3-hydroxybutyrate-co-3-hydroxyvalerate)-based porous membrane.Mechanistically,we have revealed polymer-occluded nanocrystal structure and welding-derived microstress which is much stronger than interfacial Van der Waals force,thus efficiently preventing the generation of microcracks and repairing initial microcracks by microcracks-induced hydration,crystallization and polymer welding of mCaCO_(3) nanoconcretes.Constructed porous membrane is used as wound dressing,exhibiting a special nanoplates-constructed surface topography as well as a porous structure with plentiful oriented,aligned and opened pore channels,improved hydrophilicity,water vapor permeability,anti-bacterial and cell adherence,in support of wound healing and skin structural/functional repairing.The proposed nanoconcrete-welding-polymer strategy breaks a new pathway for improving the mechanical performances of polymers. | Yingshuai Wang Yanxia Zhu Penghe Zhao Bin Wei Mingjian Fan Danyang Chen Zhaokui Jin Qianjun He | 2022 | Bioactive Materials2022,7,8: | 0 |
