1Implementation and security analysis of practical quantum secure direct communication显示文摘Rapid development of supercomputers and the prospect of quantum computers are posing increasingly serious threats to the security of communication.Using the principles of quantum mechanics,quantum communication offers provable security of communication and is a promising solution to counter such threats.Quantum secure direct communication(QSDC)is one important branch of quantum communication.In contrast to other branches of quantum communication,it transmits secret information directly.Recently,remarkable progress has been made in proof-of-principle experimental demonstrations of QSDC.However,it remains a technical feat to bring QSDC into a practical application.Here,we report the implementation of a practical quantum secure communication system.The security is analyzed in the Wyner wiretap channel theory.The system uses a coding scheme of concatenation of lowdensity parity-check(LDPC)codes and works in a regime with a realistic environment of high noise and high loss.The present system operates with a repetition rate of 1 MHz at a distance of 1.5 kilometers.The secure communication rate is 50 bps,sufficient to effectively send text messages and reasonably sized files of images and sounds.Ruoyang Qi Zhen Sun Zaisheng Lin Penghao Niu Wentao Hao Liyuan Song Qin Huang Jiancun Gao Liuguo Yin Gui-Lu Long 2019Light(Science & Applications)2019,8,1:15
2Blood-letting punctures at twelve Jing-Well points of the hand can treat cerebral ischemia in a similar manner to mannitol显示文摘A rat model of middle cerebral artery permanent occlusion was established using the modified Longa method.Successfully established model animals were treated by blood-letting puncture at twelve Jing-Well points of the hand,and/or by injecting mannitol into the caudal vein twice daily.Brain tissue was collected at 24,48 and 72 hours after modeling,and blood was collected through the retinal vein before Evans blue was injected,approximately 1 hour prior to harvesting of brain tissue.Results showed that Evans blue leakage into brain tissue and serum nitric oxide synthase activity were significantly increased in model rats.Treatment with blood-letting punctures at twelve Jing-Well points of the hand and/or injection of mannitol into the caudal vein reduced the amount of Evans blue leakage into the brain tissue and serum nitric oxide synthase activity to varying degrees.There was no significant difference between single treatment and combined treatment.Experimental findings indicate that blood-letting punctures at twelve Jing-Well points of the hand can decrease blood-brain barrier permeability and serum nitric oxide synthase activity in rats following middle cerebral artery occlusion,and its effect is similar to that of mannitol injection alone and Jing-Well points plus mannitol injection.Xuan Lu Zelin Chen Yi Guo Liang Gao Liyuan Jiang Zhongzheng Li Jianqiao Fang 2013Neural Regeneration Research2013,8,6:14
3Correlation between tongue manifestations and glucose, total cholesterol, and high-density lipoprotein cholesterol in patients with acute cerebral infarction显示文摘OBJECTIVE: To analyze the association between tongue manifestations and the levels of glucose (GLU), total cholesterol(TCH), and high-density lipoprotein cholesterol(HDL-C) in subjects with acute cerebral infarction.METHODS: Hospitalized patients with first unilateral cerebral infarction in the Neurological Department of Xuanwu Hospital were included and the correlation between tongue fur color, fur nature,and the levels of GLU,TCH, HDL-C were analyzed.RESULTS: HDL level in the thin fur group was higher than that in the thick fur group(P=0.02). The difference in the levels of GLU,TCH, and HDL-C among the groups was significant(P<0.05), classified in terms of slippery, moist, and dry fur. Further comparison between the groups by Student-Newman-Keuls test showed that GLU level in the dry fur group was the highest. Moreover, the TCH level in the slippery fur group was higher than the other two groups.CONCLUSION: A correlation between tongue manifestations and GLU, TCH, HDL-C was identified in the patients with acute cerebral infarction.Ping Liu Li Gao Juexian Song Haiping Zhao XiaoguangWu Liyuan Huang Pingping Wang Yumin Luo 2014Journal of Traditional Chinese Medicine2014,34,2:14
4Adipocyte-derived SFRP5 inhibits breast cancer cells migration and invasion through Wnt and epithelial-mesenchymal transition signaling pathways显示文摘Objective:Obesity is closely associated with metastasis in breast cancer patients.Secreted frizzled-related protein 5(SFRP5),one of the novel adipokines with anti-inflammatory properties,is associated with obesity.This study aims to study the role of SFRP5 in the crosstalk between obesity and breast cancer metastasis and identify the underlying mechanism.Methods:3T3-L1 pre-adipocytes were differentiated to mature adipocytes and a hypertrophic adipocyte model was induced with palmitic acid(PA).Cell motility was measured in MDA-MB-231 and MCF-7 breast cancer cells co-cultured with adipocytes conditioned medium(CM)with or without SFRP5 protein.Wnt and epithelialmesenchymal transition(EMT)signal pathways were investigated by western blot.Circulating SFRP5 level in 218 breast cancer patients and the association with clinicopathologic characteristics of breast cancer were further determined.Online databases ENCORI and PREDICT Plus were used to exam the link between SFRP5 and prognosis.Results:Reduced SFRP5 level was detected in the hypertrophic adipocyte model.Recombinant SFRP5 protein inhibited MDA-MB-231 and MCF-7 cells invasion and migration induced by PA-treated adipocyte CM,and SFRP5 inhibition by specific antibody reversed the effect of SFRP5.Furthermore,SFRP5 significantly inhibited Wnt and downstream EMT in breast cancer cells.Low circulating SFRP5 level correlated with body mass index(BMI),lymph node(LN)metastasis,TNM stage and high Ki67 expression in breast cancer patients.Increased SFRP5 level was associated with favorable predicted survival.Kaplan-Meier curves showed high SFRP5 level in tumor tissue was associated with better outcome of breast cancer patients.Conclusions:Our findings demonstrated SFRP5 is a vital adipokine that mediates the crosslink between obesity and the metastatic potential of breast cancer.Promotion of SFRP5 expression in the adipose microenvironment may represent a novel approach for preventing breast cancer metastasis.Wenzhong Zhou Chunmiao Ye Liang Li Liyuan Liu Fei Wang Lixiang Yu Fei Zhou Yujuan Xiang Yongjiu Wang Gengshen Yin Zhongbing Ma Qinye Fu Qiang Zhang Dezong Gao Shuya Huang Zhigang Yu 2020Chinese Journal of Cancer Research2020,32,3:5
5A model to assess fundamental and realized carrying capacities of island ecosystem:A case study in the southern Miaodao Archipelago of China显示文摘Research on carrying capacity, aiming at maintaining the limited ability of the Earth's life supporting system to sustain human development, requires a comprehensive and ecosystem-based approach to monitor and assess the localized sustainability of coupled social and ecological systems. A definition termed the ecosystem-based carrying capacity of island(EBCCI) was developed in this paper of which the indices of fundamental and realized carrying capacities of island(FCCI and RCCI) were highlighted to emphasize the inter-dependencies between social systems and ecological systems. In order to avoid the difficulties and uncertainties of direct assessment, the related assessment model was established on the basis of synthetic evaluation of inherent and external factors affecting the EBCCI. The southern Miaodao Archipelago(SMA) located in the intersection of the Bohai Sea and the Yellow Sea, China, was taken as a typical example to acquire integrated recognition of the island ecosystem and its carrying capacity so as to discuss its sustainable development. The index scores of FCCI and RCCI in the SMA were 0.818 5 and 0.712 9 out of 1.0, respectively, with acceptable uncertainties. The results showed a relatively well capacity to sustain progress and relatively well realization of the carrying capacity of island ecosystem, owing to a well capacity of ecologically regulating, general performance of both ecologically supporting and resource provisioning, and a relatively high level of social supporting system. The study implied that it was critical to optimize the inter-dependencies and to sustain the relative balance between social systems and ecological systems so as to improve the RCCI and further facilitate the sustainability of SMA. The approach proposed in this paper provides a powerful tool which is well applicative to the regional level of an oceanic island or archipelago to study the sustainable development and can be further popularized to the coastal zone.SHI Honghua SHEN Chengcheng ZHENG Wei LI Fen WANG Xiaoli CHI Yuan GUO Zhen QIAO Mingyang GAO Liyuan DING Dewen 2016Acta Oceanologica Sinica2016,35,2:4
6Sortilin promotes macrophage cholesterol accumulation and aortic atherosclerosis through lysosomal degradation of ATP-binding cassette transporter A1 protein显示文摘Sortilin is closely associated with hyperlipidemia and the risk of atherosclerosis(AS).The role of sortilin and the underlying mechanism in peripheral macrophage are not fully understood.In this study,we investigated the effect of macrophage sortilin on ATP-binding cassette transporter A1(ABCA1)expression,ABCA1-mediated cholesterol efflux,and aortic AS.Macrophage sortilin expression was upregulated by oxidized low-density lipoproteins(ox-LDLs)in both concentration-and time-dependent manners.Its expression reached the peak level when cells were incubated with 50μg/ml ox-LDL for 24 h.Overexpression of sortilin in macrophage reduced cholesterol efflux,leading to an increase in intracellular total cholesterol,free cholesterol,and cholesterol ester.Sortilin was found to bind with ABCA1 protein and suppress macrophage ABCA1 expression,resulting in a decrease in cholesterol efflux from macrophages.The inhibitory effect of sortilin in cholesterol efflux was partially reversed by treatment with chloroquine,a lysosomal inhibitor.On the contrary,the ABCA1 protein level and ABCA1-mediated cholesterol efflux is increased by sortilin short hairpin RNA transfection.The fecal and biliary cholesterol 3H-sterol from cholesterol-laden mouse peritoneal macrophage was reduced by sortilin overexpression through lentivirus vector(LV)-sortilin in low-density lipoprotein receptor knockout mice,which was prevented by co-treatment with chloroquine.Treatment with LV-sortilin reduced plasma high-density lipoprotein and increased plasma ox-LDL levels.Accordingly,aortic lipid deposition and plaque area were exacerbated,and ABCA1 expression was reduced in mice in response to infection with LV-sortilin alone.These effects of LV-sortilin were partially reversed by chloroquine.Sortilin enhances lysosomal degradation of ABCA1 protein and suppresses ABCA1-mediated cholesterol efflux from macrophages,leading to foam cell formation and AS development.Yuncheng Lv Jing Yang Anbo Gao Sha Sun Xilong Zheng Xi Chen Wei Wan Chaoke Tang Wei Xie Suyun Li Dongming Guo Tianhong Peng Guojun Zhao Liyuan Zhong 2019Acta Biochimica et Biophysica Sinica2019,51,5:4
7PSG9 promotes angiogenesis by stimulating VEGFA production and is associated with poor prognosis in hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC) is a common malignant solid tumor characterized by rich vascularization. Pregnancy-specific glycoprotein 9(PSG9) is a member of the carcinoembryonic antigen(CEA)/PSG family and is produced at high levels during pregnancy. We previously identified PSG9 as an HCC-related protein. However, the expression of PSG9 and its regulation during HCC carcinogenesis remain poorly explored. In the present study, we first found that the levels of PSG9 protein were significantly increased in the plasma of HCC patients. PSG9 overexpression also increased the proliferation ability of an HCC cell line. High expression of PSG9 was associated with angiogenesis by accelerating VEGFA expression. In addition, Cox's proportional hazards model analysis revealed that the plasma level of PSG9 was an independent prognostic factor for overall survival. We propose that PSG9 is a novel indicator of prognosis in patients with HCC and could serve as a novel therapeutic target for HCC. Furthermore,our results indicate that PSG9 protein may facilitate the development of HCC by fostering angiogenesis via promoting VEGFA production in cancer cells.Weiqi Rong Lei Yang Liyuan Yin Yanning Gao Ting Xiao Shujun Cheng 2017Science China(Life Sciences)2017,60,5:3
8Hepatitis B virus evades immune recognition via RNA adenosine deaminase ADAR1-mediated viral RNA editing in hepatocytes显示文摘HBV is considered as a“stealth”virus that does not invoke interferon(IFN)responses;however,the mechanisms by which HBV bypasses innate immune recognition are poorly understood.In this study,we identified adenosine deaminases acting on RNA 1(ADAR1),which is a key factor in HBV evasion from IFN responses in hepatocytes.Mechanically,ADAR1 interacted with HBV RNAs and deaminated adenosine(A)to generate inosine(I),which disrupted host immune recognition and thus promoted HBV replication.Loss of ADAR1 or its deficient deaminase activity promoted IFN responses and inhibited HBV replication in hepatocytes,and blocking the IFN signaling pathways released the inhibition of HBV replication caused by ADAR1 deficiency.Notably,the HBV X protein(HBx)transcriptionally promoted ADAR1 expression to increase the threshold required to trigger intrinsic immune activation,which in turn enhanced HBV escape from immune recognition,leading to persistent infection.Supplementation with 8-azaadenosine,an ADAR1 inhibitor,efficiently enhanced liver immune activation to promote HBV clearance in vivo and in vitro.Taken together,our results delineate a molecular mechanism by which HBx promotes ADAR1-derived HBV immune escape and suggest a targeted therapeutic intervention for HBV infection.Liyuan Wang Yang Sun Xiaojia Song Zehua Wang Yankun Zhang Ying Zhao Xueqi Peng Xiaodong Zhang Chunyang Li Chengjiang Gao Nailin Li Lifen Gao Xiaohong Liang Zhuanchang Wu Chunhong Ma 2021Cellular & Molecular Immunology2021,18,8:2
9CsPb(I_(x)Br_(1-x))_(3) solar cells显示文摘Owing to its nice performance, low cost, and simple solution-processing, organic-inorganic hybrid perovskite solar cell(PSC) becomes a promising candidate for next-generation high-efficiency solar cells.The power conversion efficiency(PCE) has boosted from 3.8% to 25.2% over the past ten years. Despite the rapid progress in PCE, the device stability is a key issue that impedes the commercialization of PSCs. Recently, all-inorganic cesium lead halide perovskites have attracted much attention due to their better stability compared with their organic-inorganic counterpart. In this progress report, we summarize the properties of CsPb(IxBr1-x)3 and their applications in solar cells. The current challenges and corresponding solutions are discussed. Finally, we share our perspectives on CsPb(IxBr1-x)3 solar cells and outline possible directions to further improve the device performance.Xue Jia Chuantian Zuo Shuxia Tao Kuan Sun Yixin Zhao Shangfeng Yang Ming Cheng Mingkui Wang Yongbo Yuan Junliang Yang Feng Gao Guichuan Xing Zhanhua Wei Lijun Zhang Hin-Lap Yip Mingzhen Liu Qing Shen Longwei Yin Liyuan Han Shengzhong Liu Lianzhou Wang Jingshan Luo Hairen Tan Zhiwen Jin Liming Ding 2019Science Bulletin2019,64,20:2
10A novel terbium metal-organic framework for luminescence sensing of pyridine:Synthesis,structure,selectivity,sensitivity and recyclability显示文摘One novel two-dimensional(2D)terbium-based framework[Tb(L2-)(Ac)(DMA)]n(1)(H2 L=4’-(3,5-dicarboxyphenyl)-4,2’:6’,4'-terpyridine)was successfully isolated and structurally characterized.The structural analysis reveals that two Tb3+ions in 1 are bridged by twoη1:η1:μ2 carboxylates from L2-to form a binuclear unit,which is further linked by L2-to generate a 2D layer with kgd topology.Moreover,1 displays excellent thermostability and extensive solvent stability.Luminescent measurements reveal that 1 can be used as a recyclable luminescent probe for detecting pyridine with the lowest detection lim it of 0.12 vol%,and the luminescent mechanism is also discussed.Ying Shi Liyuan He Xinxin Wang Zhilei Wu Ning Gao Huan Zhang Wenmin Wang Jianzhong Cui 2020Journal of Rare Earths2020,38,11:2
11Pathological and physiological functional cross-talks ofα-synuclein and tau in the central nervous system显示文摘α-Synuclein and tau are abundant multifunctional brain proteins that are mainly expressed in the presynaptic and axonal compartments of neurons,respectively.Previous works have revealed that intracellular deposition ofα-synuclein and/or tau causes many neurodegenerative disorders,including Alzheimer’s disease and Parkinson’s disease.Despite intense investigation,the normal physiological functions and roles ofα-synuclein and tau are still unclear,owing to the fact that mice with knockout of either of these proteins do not present apparent phenotypes.Interestingly,the co-occurrence ofα-synuclein and tau aggregates was found in post-mortem brains with synucleinopathies and tauopathies,some of which share similarities in clinical manifestations.Furthermore,the direct interaction ofα-synuclein with tau is considered to promote the fibrillization of each of the proteins in vitro and in vivo.On the other hand,our recent findings have revealed thatα-synuclein and tau are cooperatively involved in brain development in a stage-dependent manner.These findings indicate strong cross-talk between the two proteins in physiology and pathology.In this review,we provide a summary of the recent findings on the functional roles ofα-synuclein and tau in the physiological conditions and pathogenesis of neurodegenerative diseases.A deep understanding of the interplay betweenα-synuclein and tau in physiological and pathological conditions might provide novel targets for clinical diagnosis and therapeutic strategies to treat neurodegenerative diseases.Mingyue Jin Shengming Wang Xiaodie Gao Zhenyou Zou Shinji Hirotsune Liyuan Sun 2024Neural Regeneration Research2024,19,4:1
12Recent progress in perovskite solar cells:from device to commercialization显示文摘Perovskite solar cells(PSCs) are undergoing rapid development and the power conversion efficiency reaches 25.7% which attracts increasing attention on their commercialization recently.In this review,we summarized the recent progress of PSCs based on device structures,perovskite-based tandem cells,large-area modules,stability,applications and industrialization.Last,the challenges and perspectives are discussed,aiming at providing a thrust for the commercialization of PSCs in the near future.Xinhui Luo Xuesong Lin Feng Gao Yang Zhao Xiaodong Li Liqing Zhan Zexiong Qiu Jin Wang Cong Chen Lei Meng Xiaofeng Gao Yu Zhang Zijian Huang Rundong Fan Huifen Liu Yanrun Chen Xiaoxue Ren Jiahong Tang Chun-Hao Chen Dong Yang Yongguang Tu Xiao Liu Dongxue Liu Qing Zhao Jingbi You Junfeng Fang Yongzhen Wu Hongwei Han Xiaodan Zhang Dewei Zhao Fuzhi Huang Huanping Zhou Yongbo Yuan Qi Chen Zhaokui Wang Shengzhong(Frank)Liu Rui Zhu Jotaro Nakazaki Yongfang Li Liyuan Han 2022Science China Chemistry2022,65,12:1

14Thermal effects on fracture toughness of cracked straight-through Brazilian disk green sandstone and granite显示文摘Cracked straight-through Brazilian disc(CSTBD) samples prepared using two rock materials were used for thermal treatment from room temperature to 700℃. Uniaxial splitting experiments were performed using an automatic electro-hydraulic servo press to study the evolution laws of physical and fracture properties of different deep rock materials under high-temperature geological conditions. The fracture characteristics were measured using an industrial camera and digital image correlation technology to analyze the effect of high temperature on fracture properties and failure modes of the CSTBD samples after different thermal treatments. The micro-damage properties of green sandstone and granite materials were obtained using a scanning electron microscope(SEM). The following conclusions were drawn from the test results:(1) With the increasing temperature, the fracture characteristics of green sandstone and granite change from brittle fracture to plasticity fracture, the longitudinal wave velocity of granite decreases sharply at 600℃, and the damage factor reaches 0.8748 at 700℃.(2) The fracture toughness of green sandstone and granite decreases with increasing temperature;however, the decreasing range of granite is larger than that of green sandstone.(3) As the temperature increases, the fracture morphologies of green sandstone and granite materials become rougher, whereas thermal damage cracks of granite and intergranular fractures inside sandstone as well as pores of sandstone increase.(4) The crack tip opening displacement and peak strain corresponding to peak load increase with the temperature.Lei Zhou Weiting Gao Liyuan Yu Zheming Zhu Jianxing Chen Xingkai Wang 2022Journal of Rock Mechanics and Geotechnical Engineering2022,14,5:1
15Ample dietary fat reduced the risk of primary vesical calculi by inducing macrophages to engulf budding crystals in mice显示文摘Although primary vesical calculi is an ancient disease,the mechanism of calculi formation remains unclear.In this study,we established a novel primary vesical calculi model with D,L-choline tartrate in mice.Compared with commonly used melamine and ethylene glycol models,our model was the only approach that induced vesical calculi without causing kidney injury.Previous studies suggest that proteins in the daily diet are the main contributors to the prevention of vesical calculi,yet the effect of fat is overlooked.To assay the relationship of dietary fat with the formation of primary vesical calculi,D,L-choline tartrate-treated mice were fed a high-fat,low-fat,or normal-fat diet.Genetic changes in the mouse bladder were detected with transcriptome analysis.A high-fat diet remarkably reduced the morbidity of primary vesical calculi.Higher fatty acid levels in serum and urine were observed in the high-fat diet group,and more intact epithelia in bladder were observed in the same group compared with the normal-and low-fat diet groups,suggesting the protective effect of fatty acids on bladder epithelia to maintain its normal histological structure.Transcriptome analysis revealed that the macrophage differentiation-related gene C-X-C motif chemokine ligand 14(Cxcl14)was upregulated in the bladders of high-fat diet-fed mice compared with those of normal-or low-fat diet-fed mice,which was consistent with histological observations.The expression of CXCL14 significantly increased in the bladder in the high-fat diet group.CXCL14 enhanced the recruitment of macrophages to the crystal nucleus and induced the transformation of M2 macrophages,which led to phagocytosis of budding crystals and prevented accumulation of calculi.In human bladder epithelia(HCV-29)cells,high fatty acid supplementation significantly increased the expression of CXCL14.Dietary fat is essential for the maintenance of physiological functions of the bladder and for the prevention of primary vesical calculi,which provides new ideas for the reduction of morbidity of primary vesical calculi.Huiling Chen Kaiqiang Hu Yaru Liang Yuqi Gao Chenye Zeng Kang Xu Xiaojin Shi Liyuan Li Yuemiao Yin Yi Qiao Ying Qiu Qingfei Liu Zhao Wang 2022Acta Pharmaceutica Sinica B2022,12,2:1
16Influence of zinc state on the catalyst properties of Zn/HZSM-5 zeolite in 1-hexene aromatization and cyclohexane dehydrogenation显示文摘Rational design of Zn-containing HZSM-5 zeolite(Zn/HZSM-5)with high reactivity and excellent aromatization performance for olefin aromatization is crucially desired.We develop a new and uncomplicated method to synthesize Zn/HZSM-5(IMX/Z5)with superior aromatization performance in the paper.Compared to incipient wetness impregnation(IMP/Z5)and mechanical mixing(MIX/Z5),the asprepared IMX/Z5 presents a higher amount of surface ZnOH^(+)species(2.87%)while keeping identical bulk zinc content.As a result,more surface ZnOH^(+)favor both the aromatization of 1-hexene and cyclohexane dehydrogenation.For the two olefin aromatization pathways(hydrogen transfer and dehydrogenation),it is the first time found both the hydrogen transfer ability and the dehydrogenation ability increase linearly with the amount of surface ZnOH^(+)species while keeping identical bulk zinc content.We believe that the linear relationships are essential to design next generation olefin aromatization catalysts.Di Gao Yibo Zhi Liyuan Cao Liang Zhao Jinsen Gao Chunming Xu Mingzhi Ma Pengfei Hao 2022Chinese Journal of Chemical Engineering2022,35,3:1

18High-Entropy Spinel Oxide Nanofibers as Catalytic Sulfur Hosts Promise the High Gravimetric and Volumetric Capacities for Lithium–Sulfur Batteries显示文摘The exploration of new catalytic hosts is highly important to tackle the sluggish electrochemical kinetics of sulfur redox for achieving high energy density of lithium–sulfur batteries.Herein,for the first time,we present high-entropy oxide(HEO,(Mg_(0.2)Mn_(0.2)Ni_(0.2)Co_(0.2)Zn_(0.2))Fe_(2)O_(4))nanofibers as catalytic host of sulfur.The HEO nanofibers show a synergistic effect among multiple metal cations in spinel structure that enables strong chemical confinement of soluble polysulfides and fast kinetics for polysulfide conversion.Consequently,the S/HEO composite displays the high gravimetric capacity of 1368.7 mAh g^(−1) at 0.1 C rate,excellent rate capability with the discharge capacity of 632.1 mAh g^(−1) at 5 C rate,and desirable cycle stability.Furthermore,the S/HEO composite shows desirable sulfur utilization and good cycle stability under a harsh operating condition of high sulfur loading(4.6 mg cm^(−2))or low electrolyte/sulfur ratio(5μL mg^(−1)).More impressively,the high volumetric capacity of 2627.9 mAh cm^(−3) is achieved simultaneously for the S/HEO composite due to the high tap density of 1.92 g cm^(−3),nearly 2.5 times of the conventional sulfur/carbon composite.Therefore,based on high-entropy oxide materials,this work affords a fresh concept of elevating the gravimetric/volumetric capacities of sulfur cathodes for lithium–sulfur batteries.Liyuan Tian Ze Zhang Sheng Liu Guoran Li Xueping Gao 2022Energy & Environmental Materials2022,5,2:1
19β-decay Study of Tz=-3/2Proton-rich Nucleus 29S显示文摘The exotic decay of nuclei far from the stability has recently become a hot topic of nuclear structure research.The nuclide 29S is not well investigated in the A=4n+1,Tz=-3/2series of strong+β-delayed proton precursors.The decay schemes of these nuclei are characterizedZHONG Fupeng XU Xinxing LIN Chengjian WANG Jiansong LI Zhihuan YANG Lei MA Nanru WANG Dongxi WEN Peiwei SUN Lijie WU Hongyi LUO Diwen WU Chenguang JIANG Ying LIU Yang ZANG Hongliang LIANG Pengfei LI Pengjie LI Xiaojing ZHAO Qingqing SHI Guozhu MA Junbing MA Peng YU Gongming Dipikap Patel BAI Zhen YANG Feng JIA Huiming ZHANG Huanqiao WANG Jianguo YANG Yanyun MA Weihu HU Qiang JIN Shuya ZHOU Xiaohong LI Ren HOU Dongsheng LIU Minliang HU Zhengguo MA Xinwen YANG Weiqing GAO Zhihao DUAN Fangfang YU Yuechao WANG Yufeng WANG Peng ZHOU Qingwu CUI Danteng WANG Xiang HU Liyuan PAN Min ZHANG Gaolong WANG Xiaoyu 2017Annual Report of China Institute of Atomic Energy2017,,1:0
20Magnetoresistance anomaly in Fe_(5)GeTe_(2)homo-junctions induced by its intrinsic transition显示文摘Two-dimensional van der Waals(2D vdW)magnets have attracted great attention recently and possess the unprecedented advantages of incorporating high-quality vdW heterostructures and homostructures into spintronic devices,and exploring various physical phenomena or technologies.Among them,Fe_(5)GeTe_(2)(F5GT)has ferromagnetic order close to room temperature,however the magnetic properties near its intrinsic transitions and F5GT-based 2D devices remain mostly unexplored.Here,we systematically demonstrate the peculiar magnetic properties of Fe_(5)GeTe_(2)nanoflakes near its intrinsic transition temperature(Tp)which is far lower than its Curie temperature(TC)of~265 K,and firstly discover anomalous magnetoresistance effect in F5GT homo-junctions by magneto-transport measurements.The strongest anomalous Hall effect occurs around Tp which is located in a temperature range from 130 to 160 K for the F5GT nanoflakes with different thicknesses.Furthermore,negative magnetoresistance(N-MR)and butterfly-shaped magnetoresistance(B-MR)are observed in F5GT homo-junction devices,and they appeared only in an intermediate temperature range from 110 to 160 K,noticeably showing the maxima near the T_(p)rather than the lowest temperature.Our experimental results clearly reveal the significant influence of intrinsic transitions on magnetic properties of F5GT and magnetoresistance effect in F5GT homo-junction devices,which imply a new strategy to achieve highperformance 2D spintronic devices by tuning intrinsic magnetic or structural transitions in 2D vdW magnets.Ruijie Zhao Yanfei Wu Shaohua Yan Xinjie Liu He Huang Yang Gao Mengyuan Zhu Jianxin Shen Shipeng Shen Weifeng Xu Zeyu Zhang Liyuan Zhang Jingyan Zhang Xinqi Zheng Hechang Lei Ying Zhang Shouguo Wang 2023Nano Research2023,16,7:0
