| 1 | Progresses on microwave remote sensing of land surface parameters显示文摘Highly accurate observations at various scales on the land surface are urgently needed for the studies of many areas,such as hydrology,meteorology,and agriculture.With the rapid development of remote sensing techniques,remote sensing has had the capacity of monitoring many factors of the Earth's land surface.Especially,the space-borne microwave remote sensing systems have been widely used in the quantitative monitoring of global snow,soil moisture,and vegetation parameters with their all-weather,all-time observation capabilities and their sensitivities to the characteristics of land surface factors.Based on the electromagnetic theories and microwave radiative transfer equations,researchers have achieved great successes in the microwave remote sensing studies for different sensors in recent years.This article has systematically reviewed the progresses on five research areas including microwave theoretical modeling,microwave inversion on soil moisture,snow,vegetation and land surface temperatures.Through the further enrichment of remote sensing datasets and the development of remote sensing theories and inversion techniques,remote sensing including microwave remote sensing will play a more important role in the studies and applications of the Earth systems. | SHI JianCheng DU Yang DU JinYang JIANG LingMei CHAI LinNa MAO KeBiao XU Peng NI WenJian XIONG Chuan LIU Qiang LIU ChenZhou GUO Peng CUI Qian LI YunQing CHEN Jing WANG AnQi LUO HeJia WANG YinHui | 2012 | Science China Earth Sciences2012，55，7： | 24 |
| 2 | Liquid bridge force between two unequal-sized spheres or a sphere and a plane显示文摘Liquid bridge force acting between wet particles is an important property in particle characterization. This paper deals with liquid bridge force between either two unequal-sized spherical particles or a sphere and a flat plate under conditions where gravitational effect arising from bridge distortion is negligible. In order to calculate the force of the liquid bridge efflciently and accurately, expressions of liquid conflguration and liquid bridge force were derived by building a mechanical model, which assumes the liquid bridge to be circular in shape between either two unequal-sized spheres or a sphere and a plane. To assess the accuracy of the numerical results of the calculated liquid bridge forces, they were compared to the published experimental data. | Youchuan Chen Yongzhi Zhao Hongli Gao Jinyang Zheng | 2011 | Particuology2011，9，4： | 11 |
| 3 | Enhanced high-temperature performance of Li-rich layered oxide via surface heterophase coating显示文摘Li-rich layered oxides have become one of the most concerned cathode materials for high-energy lithiumion batteries, but they still suffer from poor cycling stability and detrimental voltage decay, especially at elevated temperature. Herein, we proposed a surface heterophase coating engineering based on amorphous/crystalline Li3 PO4 to address these issues for Li-rich layered oxides via a facile wet chemical method. The heterophase coating layer combines the advantages of physical barrier effect achieved by amorphous Li3 PO4 with facilitated Li+diffusion stemmed from crystalline Li3 PO4. Consequently, the modified Li(1.2) Ni(0.2) Mn(0.6) O2 delivers higher initial coulombic efficiency of 92% with enhanced cycling stability at 55 °C(192.9 mAh/g after 100 cycles at 1 C). More importantly, the intrinsic voltage decay has been inhibited as well, i.e. the average potential drop per cycle decreases from 5.96 mV to 2.99 mV. This surface heterophase coating engineering provides an effective strategy to enhance the high-temperature electrochemical performances of Li-rich layered oxides and guides the direction of surface modification strategies for cathode materials in the future. | Yuefeng Su Feiyu Yuan Lai Chen Yun Lu Jinyang Dong Youyou Fang Shi Chen Feng Wu | 2020 | Journal of Energy Chemistry2020，29，12： | 7 |
| 4 | miR-145 improves metabolic inflammatory disease through multiple pathways显示文摘Chronic inflammation plays a pivotal role in insulin resistance and type 2 diabetes,yet the mechanisms are not completely understood.Here,we demonstrated that serum LPS levels were significantly higher in newly diagnosed diabetic patients than in normal control.miR-145 level in peripheral blood mononuclear cells decreased in type 2 diabetics.LPS repressed the transcription of miR-143/145 cluster and decreased miR-145 levels.Attenuation of miR-145 activity by anti-miR-145 triggered liver inflammation and increased serum chemokines in C57BL/6 J mice.Conversely,lentivirus-mediated miR-145 overexpression inhibited macrophage infiltration,reduced body weight,and improved glucose metabolism in db/db mice.And miR-145 overexpression markedly reduced plaque size in the aorta in ApoE−/−mice.Both OPG and KLF5 were targets of miR-145.miR-145 repressed cell proliferation and induced apoptosis partially by targeting OPG and KLF5.miR-145 also suppressed NF-κB activation by targeting OPG and KLF5.Our findings provide an association of the environment with the progress of metabolic disorders.Increasing miR-145 may be a new potential therapeutic strategy in preventing and treating metabolic diseases such as type 2 diabetes and atherosclerosis. | Min He Nan Wu Man Cheong Leong Weiwei Zhang Zi Ye Rumei Li Jinyang Huang Zhaoyun Zhang Lianxi Li Xiao Yao Wenbai Zhou Naijia Liu Zhihong Yang Xuehong Dong Yintao Li Lili Chen Qin Li Xuanchun Wang Jie Wen Xiaolong Zhao Bin Lu Yehong Yang Qinghua Wang Renming Hu | 2020 | Journal of Molecular Cell Biology2020，12，2： | 7 |
| 5 | Transition of axial segregation patterns in a long rotating drum显示文摘Axial segregation of a bidisperse mixture of particles in a long rotating drum is studied using the discrete element method. Simulation results show that particle interaction is responsible for axial segregation,the patterns of which are influenced by the end wall effect. Axial segregation patterns transform under competing influences of the end walls and the particle interaction forces. The two influential factors vary with various rotational speeds and end wall friction levels. The result is the transition of different axial segregation patterns: two large-particle bands at both ends, two small-particle bands at both ends, or a random segregation pattern where either a large-particle band or small-particle band may appear at either end. | Zequn Cui Yongzhi Zhao Youchuan Chen Xiao Liu Zhengli Hua Chilou Zhou Jinyang Zheng | 2014 | Particuology2014，12，2： | 6 |
| 6 | Rarefaction and Temperature Gradient Effect on the Performance of the Knudsen Pump显示文摘The prediction of the multiscale flow in the Knudsen pump is important for understanding its pumping mechanism.However,there is little research on such interesting multiscale phenomenon in the Knudsen pumps.In this paper,a novel numerical analysis method combining the direct simulation Monte Carlo(DSMC) method with the smoothed particle hydrodynamics(SPH) method is presented for simulating the multiscale flow,which is often encountered in the application of the Knudsen pumps.Validity and accuracy of the new method are given by comparing its results with that of the previous research.Using the coupled multiscale approach,the rarefaction and the temperature drive are studied,which are two main factors on the performance of the Knudsen pumps.To investigate the effect of rarefaction on the performance of the Knudsen pump,various pump operation pressures are compared.The flow characteristics and pumping ability at different rarefaction are analyzed,and the phenomenon of the multiscale flow is also discussed.Several cases with different linear or nonlinear temperature gradients are set to investigate the effect of temperature gradient on the performance of the Knudsen pump.The flow characteristics of the Knudsen pump such as the velocity,pressure increase,and the mass flowrate are presented.A unique phenomenon,the reverse transpiration effect caused by the nonlinear temperature gradient is studied,and the reason of the significant pressure increase in the pump channel is also analyzed.Since the multiscale gas flow is widely encountered in the microflow systems,the above method and its results can also be greatly beneficial and provide significant insights for the design of the MEMS devices. | YE Jianjun YANG Jian ZHENG Jinyang DING Xianting WONG Ieong LI Weizhong CHEN Cong | 2012 | Chinese Journal of Mechanical Engineering2012，25，4： | 6 |
| 7 | Role of Co Content on Densification and Microstructure of WC–Co Cemented Carbides Prepared by Selective Laser Melting显示文摘WC–Co cemented carbides, well-known as the conventional tooling materials, have not been successfully produced by one step additive manufacturing processes such as selective laser melting(SLM) yet. The microstructure evolution as well as WC grain growth behavior has rarely been investigated in detail during SLM process. In this study, the WC–Co cemented carbides with different Co contents(12–32 wt%) were prepared by optimized SLM processes for comparative investigation of densification behavior, microstructure characterization and mechanical property. The increase in Co content in feedstock carbide granules can improve the densification behavior during SLM process. The SLM processed WC-12 Co shows larger average WC grain size and higher percentage of coarser WC grains as compared with both WC-20 Co and WC-32 Co. The microstructure characterization, combined with finite element simulation, shows the WC grain growth mechanisms include agglomeration and dissolution-deposition of WC during SLM process and agglomeration of WC is an important mechanism especially for WC–Co cemented carbides with Co content as low as 12 wt%. The comparison between horizontal(perpendicular to the SLM laser beam) and vertical(parallel to the SLM laser beam) cross sections of carbides shows that SLM process introduces a certain degree of microstructure and mechanical behavior anisotropy for WC-12 Co, WC-20 Co, and WC-32 Co. | Jinyang Liu Jian Chen Li Zhou Bingyao Liu Yang Lu Shanghua Wu Xin Deng Zhongliang Lu Zhipeng Xie Wei Liu Jianye Liu Zhi Qu | 2021 | Acta Metallurgica Sinica(English Letters)2021，34，9： | 5 |
| 8 | Traditional Chinese Medicine etiology and pathogenesis of acquired immune deficiency syndrome in simian immunodeficiency virus-infected Chinese rhesus macaques显示文摘OBJECTIVE:To investigate the traditional Chinese Medicine(TCM) etiology and pathogenesis of acquired immune deficiency syndrome(AIDS) by 18-month observation of Chinese rhesus macaques infected with simian immunodeficiency virus(SIV) mac 239.METHODS:Thirty-five healthy Chinese rhesus macaques were divided into a model group(n=30) and a control group(n=5).The model was established by inoculating monkeys intravenously with SIVmac 239.Changes in TCM symptoms after SIV infection within 18 months were then observed and recorded.Routine blood tests,SIV viral load,T-lymphocyte subsets,plasma triiodothyronine(T3),tetraiodothyronine(T4),adrenocorticotropic hormone(ACTH) and cortisol(Cor) were tested periodically during the experiment.RESULTS:During the acute infection period of SIV,model monkeys temporarily showed clinical symptoms such as diarrhea,dysphoria and slight weight loss.Decrease percentages of CD4+ T-lymphocytes were observed but levels of T3,T4,Cor,and ACTH were relatively unchanged.Monkeys in the model group during the early and middle periods of infection showed no obvious symptoms,except few monkeys exhibited transient diarrhea and reduced food intake.All variables at this stage showed normal fluctuations.In the middle period model group monkeys showed chronic and persistent diarrhea,weight loss,reduced food intake and low levels of T3 and Cor.In the late period,symptoms including emaciation,weight loss,listlessness,crouching in corners and low levels of T3 appeared.CONCLUSION:The results suggest that the rhesus monkey SIV/SAIDS model can be applied to research on TCM etiology and pathogenesis of AIDS.According to this model,the etiology of disease is the SIV virus.The pathogenesis manifests as the invasion of SIV virus,incubation of the virus,balance between virus and healthy 'Qi',damage to spleen and kidney as the disease progressed,exhaustion of vitality and finally the failure of five zang and six fu organs. | Maoqing Li Linchun Fu Yinjie Hu Miaomiao Zhang Jinyang He Zhixi Chen Jinyan Chen | 2012 | Journal of Traditional Chinese Medicine2012，32，4： | 5 |
| 9 | Recyclable Fenton-like catalyst based on zeolite Y supported ultrafine,highly-dispersed Fe_2O_3 nanoparticles for removal of organics under mild conditions显示文摘A versatile wet impregnation method was employed to conveniently and controllably deposit Fe_2O_3 nanoparticles on zeolites including commercial Y, mordenite and ZSM-5 with the similar framework Si/Al ratios and crystal sizes, respectively. The ultrafine Fe_2O_3 nanoparticles in size of 5 nm can be highly dispersed on zeolite Y matrix due to its much better wettability than ZSM-5 and mordenite. By using the obtained Fe_2O_3/zeolite composite as the heterogeneous Fenton-like catalysts, the degradation of phenol as a model reaction was systematically investigated, including the zeolite supports, particle size and dispersion of Fe_2O_3, and reaction conditions of H_2O_2 concentration, temperature, and pH value. The catalyst based on zeolite Y with Fe loading of 9% exhibited the best phenol degradation efficiency (> 90%)in neutral pH within 2 h. Its high catalytic activity in Fenton reaction can be attributed to the bifunctional properties of strong surface BrФnsted acidity and high reactivity of octahedral Fe^(3+) in the highlydispersed ultrafine Fe_2O_3 nanoparticles in size of 5 nm, which were the primary active centers to quickly decompose H_2O_2 into hydroxyl radicals. Since phenol degradation can be performed under mild conditions of ambient temperature (283-323 K) and a wide pH range (4.0-7.0), the catalysts can be easily recovered for recyclable use with stable degradation activity, which own the immense potential in deep treatment of organic pollutants in industrial wastewater. | Xuanyu Yang Xiaowei Cheng Ahmed A.Elzatahry Jinyang Chen Abdulaziz Alghamdi Yonghui Deng | 2019 | Chinese Chemical Letters2019，30，2： | 4 |
| 10 | An Internal Expansive Stress Model of Concrete under Sulfate Attack显示文摘Concrete experiences expansive deformation during sulfate attack due to internal expansive stress. Sulfate ions enter concrete pores, react with the pore solution, and produce ettringite. The production of ettringite explains the internal expansive stress that reduces the durability of concrete. In this study, the model of internal expansive stress was achieved through the Eshelby's theory, as well as the experimental results for concrete erosion. Numerical simulation indicated that internal expansive stress is not only determined by the water-to-cement ratio of concrete and the concentration of sulfate solution, but also affected by the relaxation time of concrete. | Hui Song Jiankang Chen Jinyang Jiang | 2016 | Acta Mechanica Solida Sinica2016，29，6： | 3 |

| 13 | Rapid phenotypic evolution with shallow genomic differentiation during early stages of high elevation adaptation in Eurasian Tree Sparrows显示文摘Known as the‘third polar region’,the Qinghai-Tibet Plateau represents one of the harshest highland environments in the world and yet a number of organisms thrive there.Previous studies of birds,animals and humans have focused on well-differentiated populations in later stages of phenotypic divergence.The adaptive processes during the initial phase of highland adaptation remain poorly understood.We studied a human commensal,the Eurasian Tree Sparrow,which has followed human agriculture to the Qinghai-Tibet Plateau.Despite strong phenotypic differentiation at multiple levels,in particular in muscle-related phenotypes,highland and lowland populations show shallow genomic divergence and the colonization event occurred within the past few thousand years.In a one-month acclimation experiment investigating phenotypic plasticity,we exposed adult lowland tree sparrows to a hypoxic environment and did not observe muscle changes.Through population genetic analyses,we identified a signature of polygenic adaptation,whereby shifts in allele frequencies are spread across multiple loci,many of which are associated with muscle-related processes.Our results reveal a case of positive selection in which polygenic adaptation appears to drive rapid phenotypic evolution,shedding light on early stages of adaptive evolution to a novel environment. | Yanhua Qu Chunhai Chen Ying Xiong Huishang She Yong E Zhang Yalin Cheng Shane DuBay Dongming Li Per G P Ericson Yan Hao Hongyuan Wang Hongfeng Zhao Gang Song Hailin Zhang Ting Yang Chi Zhang Liping Liang Tianyu Wu Jinyang Zhao Qiang Gao Weiwei Zhai Fumin Lei | 2020 | National Science Review2020，7，1： | 2 |
| 14 | The oral microbiome of pregnant women facilitates gestational diabetes discrimination显示文摘The oral microbiota plays an important role in the development of various diseases,whereas its association with gestational diabetes mellitus (GDM) remains largely unclear.The aim of this study is to identify biomarkers from the oral microbiota of GDM patients by analyzing the microbiome of the saliva and dental plaque samples of 111 pregnant women.We find that the microbiota of both types of oral samples in GDM patients exhibits differences and significantly varies from that of patients with periodontitis or dental caries.Using bacterial biomarkers from the oral microbiota,GDM classification models based on support vector machine and random forest algorithms are constructed.The area under curve (AUC) value of the classification model constructed by combination of Lautropia and Neisseria in dental plaque and Streptococcus in saliva reaches 0.83,and the value achieves a maximum value of 0.89 by adding clinical features.These findings suggest that certain bacteria in either saliva or dental plaque can effectively distinguish women with GDM from healthy pregnant women,which provides evidence of oral microbiome as an informative source for developing noninvasive biomarkers of GDM. | Xiaoqing Li Jiayong Zheng Xiuling Ma Bing Zhang Jinyang Zhang Wenhuan Wang Congcong Sun Yeping Wang Jianqiong Zheng Haiying Chen Jiejing Tao Hai Wang Fengyi Zhang Jinfeng Wang Hongping Zhang | 2021 | Journal of Genetics and Genomics2021，48，1： | 2 |
| 15 | The nature of irreversible phase transformation propagation in nickel-rich layered cathode for lithium-ion batteries显示文摘Ni-rich layered cathode is regarded as one of the most promising candidates to achieve lithium-ion batteries (LIBs) with high energy density. However, due to the irreversible phase transformation (IPT) and its eventual propagation from surface to the bulk of the material, Ni-rich layered cathode typically suffers from severe capacity fading, structure failure, and thermal instability, which greatly hinders its mass adoption. Hence, achieving an in-depth understanding of the IPT propagation mechanism in Ni-rich layered cathode is crucial in addressing these issues. Herein, the triggering factor of IPT propagation in Ni-rich cathode is verified to be the initial surface disordered cation mixing domain covered by a thin rock-salt phase, instead of the rock-salt phase itself. According to the density functional theory (DFT) results, it is further illustrated that the metastable cation mixing domain possesses a lower Ni migration energy barrier, which facilitates the migration of Ni ions towards the Li slab, and thus driving the propagation of IPT from surface to the bulk of the material. This finding clarifies a prevailing debate regarding the surface impurity phases of Ni-rich cathode material and reveals the origin of IPT propagation, which implies the principle and its effectiveness of tuning the surface microstructure to address the structural and thermal instability issue of Ni-rich layered cathode materials. | Feng Wu Na Liu Lai Chen Ning Li Jinyang Dong Yun Lu Guoqiang Tan Mingzhe Xu Duanyun Cao Yafei Liu Yanbin Chen Yuefeng Su | 2021 | Journal of Energy Chemistry2021，30，11： | 2 |

| 17 | Interfacial Degradation and Optimization of Li-rich Cathode Materials显示文摘High-energy and safe lithium ion batteries(LIBs)are in increasing need as the rapid development of electronic devices,electric vehicles,as well as energy storage station.Li-rich oxides have attracted a lot of attention due to their high capacity and low cost as cathode material for LIBs.However,they still suffer from the vulnerable cathode/electrolyte interface,which presents the huge challenges of surface degradation and gas release,particularly at high state of charge.Some issues of Li-rich cathode materials,such as moderate cycle stability and voltage decay,are in tight connection with electrode-electrolyte interfacial side reactions.Research in the area of interfacial degradation mechanism and optimization strategies is of great significance as for Li-rich cathode,and extensive efforts have been poured.This review aims to understand the degradation mechanism of Li-rich cathode materials,and summarize the corresponding valuable and effective optimization strategies.Based on these considerations,we also have discussed the remaining challenges and the future research direction. | Yuefeng Su Jiayu Zhao Lai Chen Ning Li Yun Lu Jinyang Dong Youyou Fang Shi Chen Feng Wu | 2021 | Chinese Journal of Chemistry2021，39，2： | 1 |

| 19 | Screening Linear and Circular RNA Transcripts from Stress Granules显示文摘Stress granules(SGs)are cytoplasmic ribonucleoprotein assemblies formed under stress conditions and are related to various biological processes and human diseases.Previous studies have reported the regulatory role of some proteins and linear RNAs in SG assembly.However,the relationship between circular RNAs(circRNAs)and SGs has not been discovered.Here,we screened both linear RNAs and circRNAs in SGs using improved total RNA sequencing of purified SG cores in mammalian cells and identified circular transcripts specifically localized in SGs.circRNAs with higher SG-related RNA-binding protein(RBP)binding abilities are more likely to be enriched in SGs.Furthermore,some SG-enriched circRNAs are differentially expressed in hepatocellular carcinoma(HCC)and adjacent tissues.These results suggest the regulatory role of circRNAs in SG formation and provide insights into the biological function of circRNAs and SGs in HCC. | Shuai Chen Jinyang Zhang Fangqing Zhao | 2023 | Genomics, Proteomics & Bioinformatics2023，21，4： | 1 |
