| 1 | Effects of minor Sc on the microstructure and mechanical properties of Al-Zn-Mg-Cu-Zr based alloys显示文摘Five kinds of Al-Zn-Mg-Cu-Zr based alloys with different Sc additions were prepared by ingot metallurgy. The effects of minor Sc on the microstructure and mechanical properties of Al-Zn-Mg-Cu-Zr based alloys were investigated using tensile tests, optical microscopy (OM), and transmission electron microscopy (TEM). The results show that the ultimate tensile strength and yield strength are improved by 94 and 110 MPa, respectively, and the elongation to failure remains at a reasonable extent (11.1%) in the Al-Zn-Mg-Cu-Zr based alloy with 0.21 wt.% Sc addition after solution heat treatment at 475°C for 40 min and then aged at 120°C for 24 h. The addition of minor Sc induces the formation of Al3(Sc,Zr) particles, which are highly effective in refining the cast microstructures, retarding recrystallization, and pinning dislocations. The increment of strength is attributed mainly to fine grain strengthening, precipitation strengthening of Al3(Sc,Zr) particles, and substructure strengthening. | LI Wenbin PAN Qinglin ZOU Liang LIANG Wenjie HE Yunbin LIU Junsheng | 2009 | Rare Metals2009，28，1： | 12 |

| 3 | β-catenin activation in hair follicle dermal stem cells in duces ectopic hair outgrowth and skin fibrosis显示文摘Hair follicle dermal sheath(DS)harbors hair follicle dermal stem cells(hfDSCs),which can be recruited to replenish DS and dermal papilla(DP).Cultured DS cells can differentiate into various cell lineages in vitro.However,it is unclear how its plasticity is modulated in vivo.Wnt/β-catenin signaling plays an important role in maintaining stem cells of various lineages and is required for HF development and regeneration.Here we report that activation ofβ-catenin in DS generates ectopic HF outgrowth(EF)by reprogramming HF epidermal cells and DS cells themselves,and endows DS cells with hair inducing ability.Epidermal homeostasis of pre-existing HFs is disrupted.Additionally,cell-autonomous progressive skin fibrosis is prominent in dermis,where the excessive fibroblasts largely originate from DS.Gene expression analysis of purified DS cells with activatedβ-catenin revealed significantly increased expression of Bmp,Fgf,and Notch ligands and administration of Bmp,Fgf,or Notch signaling inhibitor attenuates EF formation.In summary,our findings advance the current knowledge of high plasticity of DS cells and provide an insight into understanding how Wnt/β-catenin signaling controls DS cell behaviors. | Yixin Tao Qingchun Yang Lei Wang Jie Zhang Xuming Zhu Qianqian Sun Yunbin Han Qian Luo Yushu Wang Xizhi Guo Ji Wu Baojie Li Xiao Yang Lin He Gang Ma | 2019 | Journal of Molecular Cell Biology2019，11，1： | 4 |

| 6 | Directional terahertz holography with thermally active Janus metasurface显示文摘Dynamic manipulation of electromagnetic(EM)waves with multiple degrees of freedom plays an essential role in enhancing information processing.Currently,an enormous challenge is to realize directional terahertz(THz)holography.Recently,it was demonstrated that Janus metasurfaces could produce distinct responses to EM waves from two opposite incident directions,making multiplexed dynamic manipulation of THz waves possible.Herein,we show that thermally activated THz Janus metasurfaces integrating with phase change materials on the meta-atoms can produce asymmetric transmission with the designed phase delays.Such reconfigurable Janus metasurfaces can achieve asymmetric focusing of THz wave and directional THz holography with free-space image projections,and particularly the information can be manipulated via temperature and incident THz wave direction.This work not only offers a common strategy for realizing the reconfigurability of Janus metasurfaces,but also shows possible applications in THz optical information encryption,data storage,and smart windows. | Benwen Chen Shengxin Yang Jian Chen Jingbo Wu Ke Chen Weili Li Yihui Tan Zhaosong Wang Hongsong Qiu Kebin Fan Caihong Zhang Huabing Wang Yijun Feng Yunbin He Biaobing Jin Xinglong Wu Jian Chen Peiheng Wu | 2023 | Light(Science & Applications)2023，12，6： | 1 |

| 10 | Bandgap narrowing and polarization enhancement in(K,Na,Li)(Nb,Sb,Ta)O_(3)+x%Fe_(2)O_(3) lead-free ceramics for photovoltaic applications显示文摘The need for ferroelectric materials with both narrow bandgaps(Eg)and large remanent polarization(Pr)remains a key challenge to the development of high-efficiency ferroelectric photovoltaic(FPV)devices.In this work,[(K_(0.43)Na_(0.57))_(0.94)Li_(0.06)][(Nb_(0.94)Sb_(0.06))_(0.95)Ta_(0.05)]O_(3)(KNLNST)-based lead-free ceramics with narrow Eg and large P are obtained via Fe_(2)O_(3) doping.By optimizing the level of Fe_(2)O_(3) doping,a KNLNST+1.3%Fe_(2)O_(3) ceramic is fabricated that simultaneously possesses a narrow Eg of 1.74 eV and a large Pr of 27.05μC/cm^(2).These values are much superior to those of undoped KNLNST ceramics(Eg=3.1 eV and Pr=17.73μC/cm^(2)).While the large P stems from the increment of the volume ratio between the orthorhombic and tetragonal phases(Vo/VT)in KNLNST ceramics by proper amount of Fe3+doping,the narrow Eg is attributed to the coupling interaction between the Fe3+dopants and the B-site Sb3+host ions.Moreover,a switchable photovoltaic effect caused by the ferroelectric depolarization electric field(Edp)is observed in the KNLNST+1.3%Fe_(2)O_(3) ceramic-based device.Thanks to the narrower Eg and larger P,of the doped ceramic,the photovoltaic performance of the corresponding device(open-circuit voltage(Voc)=-5.28 V and short-circuit current density(JSC)=0.051μA/cm^(2))under a downward poling state is significantly superior to that of an undoped KNLNST-based device(Voc=-0.46 V and Jse=0.039μA/cm^(2)).This work offers a feasible approach to developing ferroelectric materials with narrow bandgaps and large Pr for photovoltaic applications. | Jian Chen Jiaxing Mao Zihui Wang Yanhui Dong Jinming Guo Mingkai Li Yi Zhang Yinmei Lu Yunbin He | 2023 | Journal of Advanced Ceramics2023，12，7： | 0 |
| 11 | Draft Genome of White-blotched River Stingray Provides Novel Clues for Niche Adaptation and Skeleton Formation显示文摘The white-blotched river stingray(Potamotrygon leopoldi)is a cartilaginous fish native to the Xingu River,a tributary of the Amazon River system.As a rare freshwater-dwelling cartilaginous fish in the Potamotrygonidae family in which no member has the genome sequencing information available,P.leopoldi provides the evolutionary details in fish phylogeny,niche adaptation,and skeleton formation.In this study,we present its draft genome of 4.11 Gb comprising 16,227 contigs and 13,238 scaffolds,with contig N50 of 3937 kb and scaffold N50 of 5675 kb in size.Our analysis shows that P.leopoldi is a slow-evolving fish that diverged from elephant sharks about 96 million years ago.Moreover,two gene families related to the immune system(immunoglobulin heavy constant delta genes and T-cell receptor alpha/delta variable genes)exhibit expansion in P.leopoldi only.We also identified the Hox gene clusters in P.leopoldi and discovered that seven Hox genes shared by five representative fish species are missing in P.leopoldi.The RNA sequencing data from P.leopoldi and other three fish species demonstrate that fishes have a more diversified tissue expression spectrum when compared to mammals.Our functional studies suggest that lack of the gc gene encoding vitamin D-binding protein in cartilaginous fishes(both P.leopoldi and Callorhinchus milii)could partly explain the absence of hard bone in their endoskeleton.Overall,this genome resource provides new insights into the niche adaptation,body plan,and skeleton formation of P.leopoldi,as well as the genome evolution in cartilaginous fishes. | Jingqi Zhou Ake Liu Funan He Yunbin Zhang Libing Shen Jun Yu Xiang Zhang | 2023 | Genomics, Proteomics & Bioinformatics2023，21，3： | 0 |
| 12 | Realizing simultaneously excellent energy storage and discharge properties in AgNbO_(3)based antiferroelectric ceramics via La^(3t)and Ta^(5+)co-substitution strategy显示文摘AgNbO_(3)based antiferroelectric(AFE)ceramics have large maximum polarization and low remanent polarization,and thus are important candidates for fabricating dielectric capacitors.However,their energy storage performances have been still large difference with those of lead-based AFEs because of their room-temperature ferrielectric(FIE)behavior.In this study,novel La^(3+)and Ta^(5+)co-substituted AgNbO_(3)ceramics are designed and developed.The introduction of La^(3+)and Ta^(5+)decreases the tolerance factor,reduces the polarizability of B-site cations and increases local structure heterogeneity of AgNbO_(3),which enhance AFE phase stability and refine polarization-electric field(PeE)loops.Besides,adding La^(3+)and Ta^(5+)into AgNbO_(3)ceramics causes the decrease of the grain sizes and the increase of the band gap,which contribute to increased Eb.As a consequence,a high recoverable energy density of 6.79 J/cm3 and large efficiency of 82.1%,which exceed those of many recently reported AgNbO_(3)based ceramics in terms of overall energy storage properties,are obtained in(Ag0.88La0.04)(Nb0.96Ta0.04)O_(3)ceramics.Furthermore,the discharge properties of the ceramic with discharge time of 16 ns and power density of 145.03 MW/cm3 outperform those of many lead-free dielectric ceramics. | Yuqi Zhou Shuaibing Gao Jie Huang Meng Shen Shenglin Jiang Yunbin He Qingfeng Zhang | 2023 | Journal of Materiomics2023，9，2： | 0 |
