| 1 | Microstructure and Mechanical Properties of C/C-ZrC-SiC Composites Fabricated by Reactive Melt Infiltration with Zr,Si Mixed Powders显示文摘To meet the increasing demand for advanced materials capable of operation over 2000℃for future thermal protection systems application,C/C—ZrC—SiC composites were fabricated by reactive melt infiltration(RMI) with Zr,Si mixed powders as raw materials.The structural evolution and formation mechanism of the C/C—ZrC -SiC composites were discussed,and the mechanical property of the as-prepared material was investigated by compression test.The results showed that after the RMI process,a special structure with ZrC-SiC multi-coating as outer layer and ZrC-SiC-PyC ceramics as inner matrix was formed.ZrC and SiC rich areas were formed in the composites and on the coating surface due to the formation of Zr-Si intermetallic compounds in the RMI process.Mechanical tests showed that the average compression strength of the C/C-ZrC-SiC composites was 133.86 MPa,and the carbon fibers in the composites were not seriously damaged after the RMI process. | Xin Yang Zhean Su Qizhong Huang Xiao Fang Liyuan Chai | 2013 | Journal of Materials Science & Technology2013，29，8： | 25 |
| 2 | Recent development of methanol electrooxidation catalysts for directmethanol fuel cell显示文摘Direct methanol fuel cells(DMFCs) are very promising power source for stationary and portable miniature electric appliances due to its high efficiency and low emissions of pollutants. As the key material, catalysts for both cathode and anode face several problems which hinder the commercialization of DMFCs.In this review, we mainly focus on anode catalysts of DMFCs. The process and mechanism of methanol electrooxidation on Pt and Pt-based catalysts in acidic medium have been introduced. The influences of size effect and morphology on electrocatalytic activity are discussed though whether there is a size effect in MOR catalyst is under debate. Besides, the non Pt catalysts are also listed to emphasize though Pt is still deemed as the indispensable element in anode catalyst of DMFCs in acidic medium. Different catalyst systems are compared to illustrate the level of research at present. Some debates need to be verified with experimental evidences. | Liyuan Gong Zhiyuan Yang Kui Li Wei Xing Changpeng Liu Junjie Ge | 2018 | Journal of Energy Chemistry2018，27，6： | 9 |
| 3 | Prognostic implications of epidermal growth factor receptor variant Ⅲ expression and nuclear translocation in Chinese human gliomas显示文摘Objective: To determine the prognostic implications and clinical significance of epidermal growth factor receptor variant Ⅲ(EGFRvⅢ) expression and EGFRvⅢ nuclear translocation in Chinese human gliomas.Methods: We retrospectively examined EGFRvⅢ expression and EGFRvⅢ nuclear translocation using immunohistochemistry in specimens of 240 Chinese patients with glioma, including 84 World Health Organization(WHO) II gliomas, 84 WHO Ⅲ gliomas and 72 glioblastomas(WHO IV). Factors that correlated with EGFRvⅢ and EGFRvⅢ nuclear translocation expression were analyzed by the Chi-square test. Kaplan-Meier methodology and Cox regression were used for the survival analysis.Results: Log-rank tests showed that patient age, Karnofsky performance scale(KPS) score, tumor grade,EGFRvⅢ expression, EGFRvⅢ nuclear translocation, 1 p/19 q codeletion, isocitrate dehydrogenase(IDH)mutation, Ki-67 labeling index and O6-methylguanine-DNA methyltransferase(MGMT) status(P<0.05) were significantly correlated with overall survival(OS) time. Multivariate Cox regression analysis revealed that patient age, tumor grade, EGFRvⅢ nuclear translocation, 1 p/19 q codeletion, and IDH mutation(P<0.05) were significantly correlated with OS. Patients with a high level of EGFRvⅢ nuclear translocation(≥7%) had both significantly shorter OS [hazard ratio(HR): 1.920, 95% confidence interval(95% CI): 1.228-3.003, P=0.004] and progression-free survival(PFS) times(HR: 1.661, 95% CI: 1.116-2.471, P=0.012) than those with a low level of EGFRvⅢ nuclear translocation(<7%).Conclusions: A high level of EGFRvⅢ nuclear translocation in glioma is an independent factor indicating a poor prognosis, but EGFRvⅢ expression is not an independent clinical prognostic factor. The level of EGFRvⅢ nuclear translocation maybe a novel and crucial prognostic biomarker in glioma. | Kaiyuan Yang Xiaohui Ren Liyuan Tao Peipei Wang Haihui Jiang Li Shen Yiming Zhao Yong Cui Mingxiao Li Song Lin | 2019 | Chinese Journal of Cancer Research2019，31，1： | 8 |
| 4 | Efficient and stable tin-based perovskite solar cells by introducing π-conjugated Lewis base显示文摘Tin-based perovskite solar cells(TPSCs)as the most promising candidate for lead-free PSCs have incurred extensive researches all over the world.However,the crystallization process of tin-based perovskite is too fast during the solution-deposited process,resulting in abundant pinholes and poor homogeneity that cause serious charge recombination in perovskite layer.Here,we employed theπ-conjugated Lewis base molecules with high electron density to systematically control the crystallization rate of FASnI3 perovskite by forming stable intermediate phase with the Sn-I frameworks,leading to a compact and uniform perovskite film with large increase in the carrier lifetime.Meanwhile,the introduction of theπ-conjugated systems also retards the permeation of moisture into perovskite crystal,which significantly suppresses the film degradation in air.These benefits contributed to a stabilizing power conversion efficiency(PCE)of 10.1%for the TPSCs and maintained over 90%of its initial PCE after 1000-h light soaking in air.Also,a steady-state efficiency of 9.2%was certified at the accredited test center. | Tianhao Wu Xiao Liu Xin He Yanbo Wang Xiangyue Meng Takeshi Noda Xudong Yang Liyuan Han | 2020 | Science China Chemistry2020，63，1： | 6 |
| 5 | Studies on Factors Influencing Hydrodynamic Characteristics of Plates Used in Artificial Reefs显示文摘As a simplified model of artificial reefs, a series of plate models punched with square or circular openings are designed to investigate the effects of openings on the hydrodynamic characteristics of artificial reefs. The models are grouped by various opening numbers and opening-area ratios. They are physically tested in a water flume or used in the numerical simulation to obtain the drag force in the uniform flow with different speeds. The simulation results are found in good agreement with the experimental measurements. By the non-dimensional analysis, the drag coefficient specified to each model is achieved and the effects of openings are examined. It is found that the key factor affecting the drag coefficient is the open-area ratio. Generally, the drag coefficient is a linear function of the open area ratio with a minus slope. The empirical formulae for the square and circular openings respectively are deduced by means of the multiple regression analysis based on the measured and numerical data. They will be good references for the design of new artificial reefs. As a result of numerical simulation, the vorticity contours and pressure distribution are also presented in this work to better understand the hydrodynamic characteristics of different models. | TANG Yanli YANG Wenzhao SUN Liyuan ZHAO Fenfang LONG Xiangyu WANG Gang | 2019 | Journal of Ocean University of China2019，18，1： | 6 |
| 6 | High-speed visual target tracking with mixed rotation invariant description and skipping searching显示文摘This paper proposes a novel high-speed visual target tracking system based on mixed rotation invariant description(MRID) and skipping searching method. MRID is a novel rotation invariant description of texture and edge information by annular histograms and dominant direction. It overcomes rotation variant and large computation issues in conventional LBP-HOG feature description. The skipping searching method used in tracking can remarkably decrease the computation time by avoiding repeated searching operations.The proposed tracking system contains an image sensor, a hierarchical vision processor and an actuator with2 dimensions of freedom(DOF). The vision processor integrates processors with pixel-and row-level parallelism to speed up the tracking algorithm. Experiment results show that the proposed system can achieve over 1000-fps processing speed of the tracking algorithm under 750 × 480 resolution image. | Yongxing YANG Jie YANG Zhongxing ZHANG Liyuan LIU Nanjian WU | 2017 | Science China(Information Sciences)2017，60，6： | 5 |
| 7 | Serine metabolism orchestrates macrophage polarization by regulating the IGF1–p38 axis显示文摘Serine metabolism is reportedly involved in immune cell functions, but whether and how serine metabolism regulates macrophage polarization remain largely unknown. Here, we show that suppressing serine metabolism, either by inhibiting the activity of the key enzyme phosphoglycerate dehydrogenase in the serine biosynthesis pathway or by exogenous serine and glycine restriction, robustly enhances the polarization of interferon-γ-activated macrophages (M(IFN-γ)) but suppresses that of interleukin-4-activated macrophages (M(IL-4)) both in vitro and in vivo. Mechanistically, serine metabolism deficiency increases the expression of IGF1 by reducing the promoter abundance of S-adenosyl methionine-dependent histone H3 lysine 27 trimethylation. IGF1 then activates the p38-dependent JAK–STAT1 axis to promote M(IFN-γ) polarization and suppress STAT6-mediated M(IL-4) activation. This study reveals a new mechanism by which serine metabolism orchestrates macrophage polarization and suggests the manipulation of serine metabolism as a therapeutic strategy for macrophage-mediated immune diseases. | Xiao Shan Penghui Hu Lina Ni Long Shen Yanan Zhang Zemin Ji Yan Cui Meihua Guo Haoan Wang Liyuan Ran Kun Yang Ting Wang Lei Wang Bin Chen Zhi Yao Vingjie Wu Qiujing Yu | 2022 | Cellular & Molecular Immunology2022，19，11： | 5 |
| 8 | The landscape of aging显示文摘Aging is characterized by a progressive deterioration of physiological integrity,leading to impaired functional ability and ultimately increased susceptibility to death.It is a major risk factor for chronic human diseases,including cardiovascular disease,diabetes,neurological degeneration,and cancer.Therefore,the growing emphasis on “healthy aging” raises a series of important questions in life and social sciences.In recent years,there has been unprecedented progress in aging research,particularly the discovery that the rate of aging is at least partly controlled by evolutionarily conserved genetic pathways and biological processes.In an attempt to bring full-fledged understanding to both the aging process and age-associated diseases,we review the descriptive,conceptual,and interventive aspects of the landscape of aging composed of a number of layers at the cellular,tissue,organ,organ system,and organismal levels. | Yusheng Cai Wei Song Jiaming Li Ying Jing Chuqian Liang Liyuan Zhang Xia Zhang Wenhui Zhang Beibei Liu Yongpan An Jingyi Li Baixue Tang Siyu Pei Xueying Wu Yuxuan Liu Cheng-Le Zhuang Yilin Ying Xuefeng Dou Yu Chen Fu-Hui Xiao Dingfeng Li Ruici Yang Ya Zhao Yang Wang Lihui Wang Yujing Li Shuai Ma Si Wang Xiaoyuan Song Jie Ren Liang Zhang Jun Wang Weiqi Zhang Zhengwei Xie Jing Qu Jianwei Wang Yichuan Xiao Ye Tian Gelin Wang Ping Hu Jing Ye Yu Sun Zhiyong Mao Qing-Peng Kong Qiang Liu Weiguo Zou Xiao-Li Tian Zhi-Xiong Xiao Yong Liu Jun-Ping Liu Moshi Song Jing-Dong J.Han Guang-Hui Liu | 2022 | Science China(Life Sciences)2022，65，12： | 4 |
| 9 | Tensile, creep behavior and microstructure evolution of an as-cast Ni-based K417G polycrystalline superalloy显示文摘The Ni-based K417 G superalloy is extensively applied as aeroengine components for its low cost and good mid-temperature(600–900?C) properties. Since used in as-cast state, the comprehensive understanding on its mechanical properties and microstructure evolution is necessary. In the present research,the tensile, creep behavior and microstructure evolution of the as-cast K417 G superalloy under different conditions were investigated. The results exhibit that tensile cracks tend to initiate at MC carbide and γ/γ' eutectic structure and then propagate along grain boundary. As the temperature for tensile tests increases from 21?C to 700?C, the yield strength and ultimate tensile strength of K417 G superalloy decreases slightly, while the elongation to failure decreases greatly because of the intermediate temperature embrittlement. When the temperature rises to 900?C, the yield strength and ultimate tensile strength would decrease significantly. The creep deformation mechanism varies under different testing conditions. At 760?C/645 MPa, the creep cracks initiate at MC carbides and γ/γ' eutectic structures,and propagate transgranularly. While at 900?C/315 MPa and 950?C/235 MPa, the creep cracks initiate at grain boundary and propagate intergranularly. As the creep condition changes from 760?C/645 MPa to 900?C/315 MPa and 950?C/235 MPa, the ? phase starts to raft, which reduces the creep deformation resistance and increases the steady-state deformation rate. | Beining Du Ziyang Hu Liyuan Sheng Chuanyong Cui Jinxia Yang Yufeng Zheng Xiaofeng Sun | 2018 | Journal of Materials Science & Technology2018，34，10： | 4 |
| 10 | Sortilin 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 | 2019 | Acta Biochimica et Biophysica Sinica2019，51，5： | 4 |
| 11 | Prussian Blue Analogues in Aqueous Batteries and Desalination Batteries显示文摘In the applications of large-scale energy storage,aqueous batteries are considered as rivals for organic batteries due to their environmentally friendly and low-cost nature.However,carrier ions always exhibit huge hydrated radius in aqueous electrolyte,which brings difficulty to find suitable host materials that can achieve highly reversible insertion and extraction of cations.Owing to open threedimensional rigid framework and facile synthesis,Prussian blue analogues(PBAs)receive the most extensive attention among various host candidates in aqueous system.Herein,a comprehensive review on recent progresses of PBAs in aqueous batteries is presented.Based on the application in different aqueous systems,the relationship between electrochemical behaviors(redox potential,capacity,cycling stability and rate performance)and structural characteristics(preparation method,structure type,particle size,morphology,crystallinity,defect,metal atom in highspin state and chemical composition)is analyzed and summarized thoroughly.It can be concluded that the required type of PBAs is different for various carrier ions.In particular,the desalination batteries worked with the same mechanism as aqueous batteries are also discussed in detail to introduce the application of PBAs in aqueous systems comprehensively.This report can help the readers to understand the relationship between physical/chemical characteristics and electrochemical properties for PBAs and find a way to fabricate high-performance PBAs in aqueous batteries and desalination batteries. | Chiwei Xu Zhengwei Yang Xikun Zhang Maoting Xia Huihui Yan Jing Li Haoxiang Yu Liyuan Zhang Jie Shu | 2021 | Nano-Micro Letters2021，13，11： | 4 |
| 12 | PSG9 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 | 2017 | Science China(Life Sciences)2017，60，5： | 3 |
| 13 | Benzo[a]pyrene stimulates miR-650 expression to promote the pathogenesis of fatty liver disease and hepatocellular carcinoma via SOCS3/JAK/STAT3 cascades显示文摘Modern diets,which often feature high levels of fat and charcoal-grilled meat,contribute to the pathogenesis of obesity and non-alcoholic fatty liver disease(NAFLD),resulting in liver cancer progression.Benzo(a)pyrene(B[a]P)is a common environ-mental and foodborne pollutant found in smoke and fire-grilled foods,which can have an adverse effect on human health.Hepatocellular carcinoma(HCC)is the fifth leading cause of cancer and the second leading cause of cancer-related deaths worldwide.The epidemiological studies suggest that both environmental risk factors and chronic liver injury including NAFL are important for HCC development,but the precise mechanisms linking eating habits to hepato-carcinogenesis remain unclear.In the present study,we demonstrated that various miRNAs in B[a]P-exposed tumor cells contribute to tumor metastasis,among which miR-650 could be the most potent inducer.Furthermore,we found that the suppressor of cytokine signaling 3(SOCS3)is directly regulated by miR-650 and its suppression regulates the activation of the Janus kinase/signal transducer and activator of transcription 3 (JAK/STAT3)cascade.Our findings reveal a possible adverse outcome pathway of SOCS3/JAK/STAT3 regulation in B[a]P-induced HCC progress.These results provide a better understanding of the adverse effects of chronic exposure to B[a]P on human health. | Yang Ge Pengfei Gu Wenbo Wang Liyuan Cao Lulu Zhang Jingquan Li Wei Mu Hui Wang | 2021 | Journal of Molecular Cell Biology2021，13，8： | 3 |
| 14 | High-risk phenotypes of genetic disease in a Neonatal Intensive Care Unit population显示文摘To the Editor: Genetic diseases contribute to 35% of deaths during the first year of life and are a significant cause of intensive care.[1] A previous study based on the China Neonatal Genomes Project investigated the genetic causes of early infant deaths and found that >25% of deceased neonates with genetic diagnoses can be cured if diagnosed in time.[2] Therefore, it is crucial to target and diagnose neonates with genetic diseases as early as possible. According to our experience, the typical phenotypes, such as special facial features or multiple congenital anomalies (MCAs), indicate a high risk of genetic disease and lead physicians to perform genetic testing in neonates as early as possible. However, in practice, infants without typical phenotypes typically undergo a long and costly diagnostic process before genetic diagnoses are confirmed. Moreover, a recent survey by the American College of Medical Genetics and Genomics (ACMG) and other national professional organizations indicated that there are insufficient numbers of qualified geneticists to fulfil genetic service needs.[3] The ACMG published the general clinical features for genetic testing indications. For example, patients with phenotypes or family history data that strongly implicate a genetic cause may undergo genetic testing.[1] However, the study indicated that many genetic conditions arise de novo or are inherited with no family history.[1] A previous study attempted to apply the non-phenotype-driven panel approach in neonates admitted to the neonate intensive care unit (NICU).[4] However, at present, the diagnostic yield is only 3.45% (1/29).[4] In addition, the economic and ethical issues associated with genomic screening remain challenging. Therefore, the available indications for genetic testing may improve the management of genetic diseases. | Tiantian Xiao Qi Ni Huiyao Chen Huijun Wang Lin Yang Bingbing Wu Yun Cao Guoqiang Cheng Laishuan Wang Liyuan Hu Hongfang Mei Yulan Lu Mengchun Gong Xinran Dong Wenhao Zhou | 2022 | Chinese Medical Journal2022，，5： | 2 |
| 15 | Hydrogen Bond-Assisted Ultra-Stable and Fast Aqueous NH_(4)^(+)Storage显示文摘Aqueous ammonium ion batteries are regarded as eco-friendly and sustainable energy storage systems.And applicable host for NH_(4)^(+)in aqueous solution is always in the process of development.On the basis of density functional theory calcula-tions,the excellent performance of NH_(4)^(+)insertion in Prussian blue analogues(PBAs)is proposed,especially for copper hexacyanoferrate(CuHCF).In this work,we prove the outstanding cycling and rate performance of CuHCF via electrochemical analyses,delivering no capacity fading during ultra-long cycles of 3000 times and high capacity retention of 93.6%at 50 C.One of main contributions to superior performance from highly reversible redox reaction and structural change is verified during the ammoniation/de-ammoniation progresses.More importantly,we propose the NH_(4)^(+)diffusion mechanism in CuHCF based on con-tinuous formation and fracture of hydrogen bonds from a joint theoretical and experimental study,which is another essential reason for rapid charge transfer and superior NH_(4)^(+)storage.Lastly,a full cell by coupling CuHCF cathode and polyaniline anode is constructed to explore the practical application of CuHCF.In brief,the outstanding aqueous NH_(4)^(+)storage in cubic PBAs creates a blueprint for fast and sustainable energy storage. | Xikun Zhang Maoting Xia Haoxiang Yu Junwei Zhang Zhengwei Yang Liyuan Zhang Jie Shu | 2021 | Nano-Micro Letters2021，13，9： | 2 |
| 16 | Hepatitis 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 | 2021 | Cellular & Molecular Immunology2021，18，8： | 2 |
| 17 | CsPb(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 | 2019 | Science Bulletin2019，64，20： | 2 |
| 18 | Phylogenetic Analysis of the Dengue Virus Strains Causing the 2019 Dengue Fever Outbreak in Hainan,China显示文摘Dengue virus is an arthropod-borne pathogen that is transmitted to humans primarily by Aedes spp.mosquitos,causing the acute infectious disease,dengue fever(DF).Until 2019,no dengue outbreak had been reported in Hainan Province for over 20 years.However,in early September of 2019,an increasing number of infected cases appeared and the DF outbreak lasted for over one month in Haikou City,Hainan Province.In our study,we collected 97 plasma samples from DF patients at three hospitals,as well as 1585 mosquito larvae samples from puddles in different areas of Haikou.There were 49(50.5%)plasma samples found to be strongly positive and 9(9.3%)plasma samples were weakly positive against the NS1 antigen.We discovered DENV both in the patient's plasma samples and mosquito larvae samples,and isolated the virus from C6/36 cells inoculated with the acute phase serum of patients.Phylogenetic analysis revealed that the new strains were the most closely related to the epidemic strain in the southern regions of China,belonging to lineageⅣ,genotypeⅠ,DENV-1.Compared to the seven closest strains from neighboring countries and provinces,a total of 18 amino acid mutations occurred in the coding sequences(CDS)of the new isolated strain,DENV1 HMU-HKU-2.Our data shows that dengue virus is re-emerged in Hainan,and pose new threats for public health.Thus regular molecular epidemiological surveillance is necessary for control and prevention of DENV transmission. | Jiang Du Liyuan Zhang Xiaoyuan Hu Ruoyan Peng Gaoyu Wang Yi Huang Wenqi Wang Kunliang Wu Qiang Wang Haoxiang Su Fan Yang Yun Zhang Chuanning Tang Xiuji Cui Lina Niu Gang Lu Meifang Xiao Yongguo Du Feifei Yin | 2021 | Virologica Sinica2021，36，4： | 2 |
| 19 | M5B3 Boride at the Grain Boundary of a Nickel-based Superalloy显示文摘The grain boundary microstructures of a heat-treated Ni-based cast superalloy IN792 were investigated. The results show that M_5B_3 boride precipitates at the grain boundary. A special orientation relationship between M_5B_3 phase and the matrix at one side of the grain boundary is found. At the same time, two M_5B_3 borides with different orientations could co-exist in a single M_5B_3 particle as an intergrowth besides existing alone, thus forming orientation relationship between the two M_5B_3 phases and matrix. This phenomenon could be attributed to the special orientation relationship between M_5B_3 phase and the matrix. | Beining Du Zhiwu Shi Jinxia Yang Zhaokuang Chu Chuanyong Cui Xiaofeng Sun Liyuan Sheng Yufeng Zheng | 2016 | Journal of Materials Science & Technology2016，32，3： | 2 |
| 20 | Defective arginine metabolism impairs mitochondrial homeostasis in Caenorhabditis elegans显示文摘Arginine catabolism involves enzyme-dependent reactions in both mitochondria and the cytosol,defects in which may lead to hyperargininemia,a devastating developmental disorder.It is largely unknown if defective arginine catabolism has any effects on mitochondria.Here we report that normal arginine catabolism is essential for mitochondrial homeostasis in Caenorhabditis elegans.Mutations of the arginase gene argn-1 lead to abnormal mitochondrial enlargement and reduced adenosine triphosphate(ATP)production in C elegans hypodermal cells.ARGN-1 localizes to mitochondria and its loss causes arginine accumulation,which disrupts mitochondrial dynamics.Heterologous expression of human ARGl or ARG2 rescued the mitochondrial defects of argn-1 mutants.Importantly,genetic inactivation of the mitochondrial basic amino acid transporter SLC-25A29 or the mitochondrial glutamate transporter SLC-25A18.1 fully suppressed the mitochondrial defects caused by argn-1 mutations.These findings suggest that mitochondrial damage probably contributes to the pathogenesis of hyperargininemia and provide clues for developing therapeutic treatments for hyperargininemia. | Ruofeng Tang Xin Wang Junxiang Zhou Fengxia Zhang Shan Zhao Qiwen Gan Liyuan Zhao Fengyang Wang Qian Zhang Jie Zhang Guodong Wang Chonglin Yang | 2020 | Journal of Genetics and Genomics2020，47，3： | 2 |
