| 1 | Onset of the Meissner effect at 65 K in Fe Se thin film grown on Nb-doped Sr TiO_3 substrate显示文摘We report the Meissner effect studies on an Fe Se thin film grown on Nb-doped Sr Ti O3 substrate by molecular beam epitaxy. Two-coil mutual inductance measurement clearly demonstrates the onset of diamagnetic screening at 65 K, which is consistent with the gap opening temperature determined by previous angle-resolved photoemission spectroscopy results. The applied magnetic field causes a broadening of the superconducting transition near the onset temperature, which is the typical behavior for quasi-two-dimensional superconductors. Our results provide direct evidence that Fe Se thin film grown on Nb-doped Sr Ti O3 substrate has an onset TC* 65 K,which is the highest among all iron-based superconductors discovered so far. | Zuocheng Zhang Yi-Hua Wang Qi Song Chang Liu Rui Peng K.A.Moler Donglai Feng Yayu Wang | 2015 | Science Bulletin2015，60，14： | 10 |
| 2 | Mycorrhizal symbiosis modulates the rhizosphere microbiota to promote rhizobia–legume symbiosis显示文摘Plants establish symbioses with mutualistic fungi,such as arbuscular mycorrhizal(AM)fungi,and bacteria,such as rhizobia,to exchange key nutrients and thrive.Plants and symbionts have coevolved and represent vital components of terrestrial ecosystems.Plants employ an ancestral AM signaling pathway to establish intracellular symbioses,including the legume–rhizobia symbiosis,in their roots.Nevertheless,the relationship between the AM and rhizobial symbioses in native soil is poorly understood.Here,we examined how these distinct symbioses affect root-associated bacterial communities in Medicago truncatula by performing quantitative microbiota profiling(QMP)of 16S rRNA genes.We found that M.truncatula mutants that cannot establish AM or rhizobia symbiosis have an altered microbial load(quantitative abundance)in the rhizosphere and roots,and in particular that AM symbiosis is required to assemble a normal quantitative root-associated microbiota in native soil.Moreover,quantitative microbial co-abundance network analyses revealed that AM symbiosis affects Rhizobiales hubs among plant microbiota and benefits the plant holobiont.Through QMP of rhizobial rpoB and AM fungal SSU rRNA genes,we revealed a new layer of interaction whereby AM symbiosis promotes rhizobia accumulation in the rhizosphere of M.truncatula.We further showed that AM symbiosis-conditioned microbial communities within the M.truncatula rhizosphere could promote nodulation in different legume plants in native soil.Given that the AM and rhizobial symbioses are critical for crop growth,our findings might inform strategies to improve agricultural management.Moreover,our work sheds light on the co-evolution of these intracellular symbioses during plant adaptation to native soil conditions. | Xiaolin Wang Huan Feng Yayu Wang Mingxing Wang Xingguang Xie Huizhong Chang Like Wang Jicheng Qu Kai Sun Wei He Chunyan Wang Chuanchao Dai Zhaohui Chu Changfu Tian Nan Yu Xuebin Zhang Huan Liu Ertao Wang | 2021 | Molecular Plant2021，14，3： | 6 |

| 4 | Relationship between the parent charge transfer gap and maximum transition temperature in cuprates显示文摘One of the biggest puzzles concerning the cuprate high temperature superconductors is what determines the maximum transition temperature(Tc,max), which varies from less than 30 to above 130 K in different compounds.Despite this dramatic variation, a robust trend is that within each family, the double-layer compound always has higher Tc,maxthan the single-layer counterpart. Here we use scanning tunneling microscopy to investigate the electronic structure of four cuprate parent compounds belonging to two different families. We find that within each family, the double layer compound has a much smaller charge transfer gap size(DCT), indicating a clear anticorrelation between DCTand Tc,max. These results suggest that the charge transfer gap plays a key role in the superconducting physics of cuprates, which shed important new light on the high Tc mechanism from doped Mott insulator perspective. | Wei Ruan Cheng Hu Jianfa Zhao Peng Cai Yingying Peng Cun Ye Runze Yu Xintong Li Zhenqi Hao Changqing Jin Xingjiang Zhou Zheng-Yu Weng Yayu Wang | 2016 | Science Bulletin2016，61，23： | 3 |
| 5 | Cold-induced Yes-associated-protein expression through miR-429 mediates the browning of white adipose tissue显示文摘Targeting the white-to-brown fat conversion is important for developing potential strategies to counteract metabolic diseases;yet the mechanisms are not fully understood.Yes-associated-protein(YAP),a transcription co-activator,was demonstrated to regulate adipose tissue functions;however,its effects on browning of subcutaneous white adipose tissue(sWAT)are unclear.We demonstrated that YAP was highly expressed in cold-induced beige fat.Mechanistically,YAP was found as a target gene of miR-429,which downregulated YAP expression in vivo and in vitro.In addition,miR-429 level was decreased in cold-induced beige fat.Additionally,pharmacological inhibition of the interaction between YAP and transcriptional enhanced associate domains by verteporfin dampened the browning of sWAT.Although adipose tissue-specific YAP overexpression increased energy expenditure with increased basal uncoupling protein 1 expression,it had no additional effects on the browning of sWAT in young mice.However,we found age-related impairment of sWAT browning along with decreased YAP expression.Under these circumstances,YAP overexpression significantly improved the impaired WAT browning in middle-aged mice.In conclusion,YAP as a regulator of sWAT browning,was upregulated by lowering miR-429 level in cold-induced beige fat.Targeting the miR-429-YAP pathway could be exploited for therapeutic strategies for age-related impairment of sWAT browning. | Chenji Ye Jinjie Duan Xuejiao Zhang Liu Yao Yayue Song Guangyan Wang Qi Li Biqing Wang Ding Ai Chunjiong Wang Yi Zhu | 2021 | Science China(Life Sciences)2021，64，3： | 1 |

| 11 | Atomic scale electronic structure of the ferromagnetic semiconductor Cr2Ge2Te6显示文摘Cr_2Ge_2Te_6is an intrinsic ferromagnetic semiconductor with van der Waals type layered structure,thus represents a promising material for novel electronic and spintronic devices.Here we combine scanning tunneling microscopy and first-principles calculations to investigate the electronic structure of Cr_2Ge_2Te_6.Tunneling spectroscopy reveals a surprising large energy level shift and change of energy gap size across the ferromagnetic to paramagnetic phase transition,as well as a peculiar double-peak electronic state on the Cr-site defect.These features can be quantitatively explained by density functional theory calculations,which uncover a close relationship between the electronic structure and magnetic order.These findings shed important new lights on the microscopic electronic structure and origin of magnetic order in Cr_2Ge_2Te_6. | Zhenqi Hao Haiwei Li Shunhong Zhang Xintong Li Gaoting Lin Xuan Luo Yuping Sun Zheng Liu Yayu Wang | 2018 | Science Bulletin2018，63，13： | 1 |
| 12 | Metal-organic frameworks with mixed-ligands strategy as heterogeneous nucleation center to assist crystallization for efficient and stable perovskite solar cells显示文摘Deep-level defects and random oriented configuration in perovskite crystallization process would cause the nonradiative recombination and further affect the performance of perovskite solar cells(PSCs).Herein,two metal-organic frameworks(MOFs)with tunable Lewis-base passivation sites have been constructed(Cd-Httb and Cd-Httb-BDC,Httb=5-(4-(1H-1,2,4-triazole-1-yl)benzyl)-1h-tetrazole,BDC=1,4-dicarboxybenzene)to eliminate deep-level defects and simultaneously as nanostructured heterogeneous nucleation seed to assist the growth of large-grained perovskite films.Compared with the control and Cd-Httb,Cd-Httb-BDC designed with mix-ligands strategy exhibited the enhanced inducted effect on the crystallization and nucleation of high-quality perovskite films during annealing process.Consequently,the resultant Cd-Httb-BDC-modified device achieved higher power conversion efficiency(PCE)(22.18%)than the control(20.89%)and Cd-Httb(21.56%).Meanwhile,the unencapsulated Cd-Httb-BDC-modified device still maintained 90%of initial PCE after 1500 h in ambient conditions and exhibited enhanced thermal stability(85℃ in N_(2) atmosphere).This work presented a successful example of mixligands strategy on construction of high-quality MOF-assisted perovskite films for high-efficient and stable PSCs. | Yayu Dong Shuang Gai Jian Zhang Ruiqing Fan Boyuan Hu Wei Wang Wei Cao Jiaqi Wang Ke Zhu Debin Xia Lin Geng Yulin Yang | 2023 | Journal of Energy Chemistry2023，，2： | 0 |
| 13 | Quantized anomalous Hall resistivity achieved in molecular beam epitaxy-grown MnBi_(2)Te_(4)thin films显示文摘The intrinsic magnetic topological insulator MnBi_(2)Te_(4)provides a feasible pathway to the high-temperature quantum anomalous Hall(QAH)effect as well as various novel topological quantum phases.Although quantized transport properties have been observed in exfoliated MnBi_(2)Te_(4)thin flakes,it remains a big challenge to achieve molecular beam epitaxy(MBE)-grown MnBi_(2)Te_(4)thin films even close to the quantized regime.In this work,we report the realization of quantized anomalous Hall resistivity in MBE-grown MnBi_(2)Te_(4)thin films with the chemical potential tuned by both controlled in situ oxygen exposure and top gating.We find that elongated post-annealing obviously elevates the temperature to achieve quantization of the Hall resistivity,but also increases the residual longitudinal resistivity,indicating a picture of high-quality QAH puddles weakly coupled by tunnel barriers.These results help to clarify the puzzles in previous experimental studies on MnBi_(2)Te_(4)and to find a way out of the big difficulty in obtaining MnBi_(2)Te_(4)samples showing quantized transport properties. | Yunhe Bai Yuanzhao Li Jianli Luan Ruixuan Liu Wenyu Song Yang Chen Peng-Fei Ji Qinghua Zhang Fanqi Meng Bingbing Tong Lin Li Yuying Jiang Zongwei Gao Lin Gu Jinsong Zhang Yayu Wang Qi-Kun Xue Ke He Yang Feng Xiao Feng | 2024 | National Science Review2024，11，2： | 0 |
| 14 | Progress on the antiferromagnetic topological insulator MnBi_(2)Te_(4)显示文摘Topological materials,which feature robust surface and/or edge states,have now been a research focus in condensed matter physics.They represent a new class of materials exhibiting nontrivial topological phases,and provide a platform for exploring exotic transport phenomena,such as the quantum anomalous Hall effect and the quantum spin Hall effect.Recently,magnetic topological materials have attracted considerable interests due to the possibility to study the interplay between topological and magnetic orders.In particular,the quantum anomalous Hall and axion insulator phases can be realized in topological insulators with magnetic order.MnBi_(2)Te_(4),as the first intrinsic antiferromagnetic topological insulator discovered,allows the examination of existing theoretical predictions;it has been extensively studied,and many new discoveries have been made.Here we review the progress made on MnBi_(2)Te_(4)from both experimental and theoretical aspects.The bulk crystal and magnetic structures are surveyed first,followed by a review of theoretical calculations and experimental probes on the band structure and surface states,and a discussion of various exotic phases that can be realized in MnBi_(2)Te_(4).The properties of MnBi_(2)Te_(4)thin films and the corresponding transport studies are then reviewed,with an emphasis on the edge state transport.Possible future research directions in this field are also discussed. | Shuai Li Tianyu Liu Chang Liu Yayu Wang Hai-Zhou Lu X.C.Xie | 2024 | National Science Review2024，11，2： | 0 |
| 15 | Molecular characterization and expression of the feminization-1c (fem1c) in the freshwater mussel (Hyriopsis cumingii)显示文摘The feminization-1c(fem-1c)gene has been shown to be associated with sex differentiation and determination in many metazoan species.It belongs to the fem-1 family which is a member of the ANK superfamily.In this study,the full-length cDNA of the fem-1c(Hcfem-1c)gene was isolated from the freshwater mussel(Hypriopsis cumingii).The isolated Hcfem-1c cDNA was 2196 bp in length and encoded a putative protein of 621 amino acids that contains seven ANK domains.Phylogenetic analysis of the deduced HcFEM-1C protein showed that it clustered with the other invertebrates homologues,indicating that the sequence of HcFEM-1C was conserved during evolution.Quantitative real-time PCR(qPCR)expression revealed that the Hcfem-1c gene was expressed in the adductor muscle,foot,liver,gill,kidney,mantle,and gonads of male and female adult mussels(two years old).In the gonads Hcfem-1c was much less abundant in males than that in females.During early development of the gonads,Hcfem-1c transcripts were significantly increased in the primordial germ cell differentiation stage(5 months old).We hypothesized that Hcfem-1c probably regulates female gonad differentiation.In situ hybridization showed that a strong and specific signal concentrated in the female oocyte cell membrane and male follicular wall,indicating that Hcfem-1c gene may not only be involved in female gonad differentiation,but also participates in egg development.This study laid the foundations for a better understanding of gender differentiation mechanism in H.cumingii. | Yayu Wang Congdi Wu Pengfei Guo Guiling Wang Jiale Li | 2018 | Aquaculture and Fisheries2018，3，1： | 0 |
| 16 | Heat diffusion optimization in high performance perovskite solar cells integrated with zeolite显示文摘Heat accumulation inside perovskite solar cells causes the decomposition of the perovskite layer and hole transport materials(HTMs)under working conditions,yielding a decrease in long-term stability.Here,we present a zeolite-assisted heat conduction strategy by introducing economic zeolite crystals(e.g.,NaX,NaY,and ZSM-5)as a cooling filter to induce heat diffusion.The fitted thermal diffusion kinetic equation from real-time infrared thermal imaging technology reveals the zeolite skeleton assisted thermal co nduction mechanism of internal lattice vibration.Additionally,the nearly twofold improved conductivity of the modified HTM film is benefited from Na^(+)hopping on the supercages of the zeolite,therefore,the best-performed device with a rapid heat diffusion and defect inhibition obtains a remarkable power conversion efficiency of 23.42%.Both of NaX modified sprio-OMeTAD and PTAA based devices exhibit excellent operational stability after heating 1000 h at 85℃under N_(2)condition.This work demonstrates the potential application of economical porous zeolite materials in improving the thermal stability of PSCs. | Wei Wang Jian Zhang Kaifeng Lin Jiaqi Wang Boyuan Hu Yayu Dong Debin Xia Yulin Yang | 2023 | Journal of Energy Chemistry2023，，11： | 0 |
| 17 | Positive Effects of Isopropanol as a Co-Precipitant in Glycerol-3-Phosphate Acyltransferase Crystallization显示文摘Glycerol-3-phosphate acyltransferase(GPAT) is considered as the rate-limiting enzyme of glycerolipid synthesis pathway and the core element in lysophosphatidic acid(LPA) synthesis. For understanding its catalytic mechanism, the structural biology study is expected, but is always hindered by obtaining crystals for X-ray diffraction analysis. In this study, a progressive strategy to optimize the crystal of microalgae plastidial GPAT was presented. After the expression and purification of GPAT, the crystals were screened by hanging-drop and only clusters were obtained. The crystals were optimized by adjusting temperature, pH, protein concentration, or precipitant, but little improvement. To improve the interaction between protein and precipitant, the isopropanol was applied as co-precipitant. The qualified crystals formed. It's suggested that isopropanol is critical to affect protein crystallization by altering polyethylene glycol(PEG)-water-protein interaction when PEG serves as precipitant. The resulting crystal diffracted to a resolution of 2.75 ? and belonged to space group P1, with unit-cell parameters a = 50.79, b = 80.09, c = 88.21 ?, and α = 62.85, β = 73.04, γ = 80.53?. This work introduced a new strategy to optimize the crystal of the heterogeneous catalysis enzymes like GPAT and provided the fundamental structural information for the oriented synthesis of marine microalgae glycerolipid. | ZHANG Yunxiu FENG Yanbin WANG Yayue LIU Yinghui CAO Xupeng XUE Song | 2019 | Journal of Ocean University of China2019，18，1： | 0 |
| 18 | Transplantation of neural stem progenitor cells from different sources for severe spinal cord injury repair in rat显示文摘Neural stem progenitor cell(NSPC)transplantation has been regarded as a promising therapeutic method for spinal cord injury(SCI)repair.However,different NSPCs may have different therapeutic effects,and it is therefore important to identify the optimal NSPC type.In our study,we compared the transcriptomes of human fetal brain-derived NSPCs(BNSPCs),spinal cord-derived NSPCs(SCNSPCs)and H9 embryonic stem-cell derived NSPCs(H9-NSPCs)in vitro and subsequently we transplanted each NSPC type on a collagen scaffold into a T8-9 complete SCI rat model in vivo.In vitro data showed that SCNSPCs had more highly expressed genes involved in nerve-related functions than the other two cell types.In vivo,compared with BNSPCs and H9-NSPCs,SCNSPCs exhibited the best therapeutic effects;in fact,SCNSPCs facilitated electrophysiological and hindlimb functional recovery.This study demonstrates that SCNSPCs may be an appropriate candidate cell type for SCI repair,which is of great clinical significance. | Bai Xu Man Yin Yaming Yang Yunlong Zou Wenbin Liu Lianyong Qiao Jixiang Zhang Zhan Wang Yayu Wu He Shen Minghan Sun Weiyuan Liu Weiwei Xue Yongheng Fan Qi Zhang Bing Chen Xianming Wu Ya Shi Falong Lu Yannan Zhao Zhifeng Xiao Jianwu Dai | 2023 | Bioactive Materials2023，，5： | 0 |
| 19 | Cdx1b protects intestinal cell fate by repressing signaling networks for liver specification显示文摘In mammals,the expression of the homeobox family member Cdx2/CDX2 is restricted within the intestine.Conditional ablation of the mouse Cdx2 in the endodermal cells causes a homeotic transformation of the intestine towards the esophagus or gastric fate.In this report,we show that null mutants of zebrafish cdx1b,encoding the counterpart of mammalian CDX2,could survive more than 10 days post fertilization,a stage when the zebrafish digestive system has been well developed.Through RNA sequencing(RNA-seq)and single-cell sequencing(sc RNA-seq)of the dissected intestine from the mutant embryos,we demonstrate that the loss-of-function of the zebrafish cdx1b yields hepatocyte-like intestinal cells,a phenotype never observed in the mouse model.Further RNA-seq data analysis,and genetic double mutants and signaling inhibitor studies reveal that Cdx1b functions to guard the intestinal fate by repressing,directly or indirectly,a range of transcriptional factors and signaling pathways for liver specification.Finally,we demonstrate that heat shock-induced overexpression of cdx1b in a transgenic fish abolishes the liver formation.Therefore,we demonstrate that Cdx1b is a key repressor of hepatic fate during the intestine specification in zebrafish. | Qingxia Jin Yuqi Gao Shimin Shuai Yayue Chen Kaiyuan Wang Jun Chen Jinrong Peng Ce Gao | 2022 | Journal of Genetics and Genomics2022，49，12： | 0 |
