| 1 | Pressure-induced robust emission in a zero-dimensional hybrid metal halide (C_(9)NH_(20))_(6)Pb_(3)Br_(12)显示文摘Zero-dimensional(0D)hybrid metal halides are under intensive investigation owing to their unique physical properties,such as the broadband emission from highly localized excitons that is promising for white-emitting lighting.However,fundamental understanding of emission variations and structure–property relationships is still limited.Here,by using pressure processing,we obtain robust exciton emission in 0D(C_(9)NH_(20))_(6)Pb_(3)Br_(12) at room temperature that can survive to 80 GPa,the recorded highest value among all the hybrid metal halides.In situ experimental characterization and first-principles calculations reveal that the pressure-induced emission is mainly caused by the largely suppressed phonon-assisted nonradiative pathway.Lattice compression leads to phonon hardening,which considerably weakens the exciton–phonon interaction and thus enhances the emission.The robust emission is attributed to the unique structure of separated spring-like[Pb_(3)Br_(12)]^(6−)trimers,which leads to the outstanding stability of the optically active inorganic units.Our findings not only reveal abnormally robust emission in a 0D metal halide,but also provide new insight into the design and optimization of local structures of trimers and oligomers in lowdimensional hybrid materials. | Mengting Chen Songhao Guo Kejun Bu Sujin Lee Hui Luo Yiming Wang Bingyan Liu Zhipeng Yan Hongliang Dong Wenge Yang Biwu Ma Xujie Lü | 2021 | Matter and Radiation at Extremes2021，6，5： | 1 |
| 2 | Free-ranging livestock altered the spatiotemporal behavior of the endangered North Chinese leopard (Panthera pardus japonensis) and its prey and intensified human–leopard conflicts显示文摘Widespread distribution of livestock in the natural habitats of large carnivores may negatively impact carnivore populations by reducing wild prey availability and increasing human–carnivore conflicts.In this study,we used camera-trapping data collected in the temperate forests of the Taihang Mountains in North China during 2016–2019 to examine whether and how free-ranging cattle affected habitat use and Diel activity patterns of the endangered North Chinese leopard(Panthera pardus japonensis)and its 2 wild prey species,Siberian roe deer(Capreolus pygargus),and wild boar(Sus scrofa).Residents were also interviewed to record livestock depredation events by leopards during 2015–2019.We found that roe deer spatially avoided sites frequented by cattle,but wild boar did not.In the growing seasons,leopards shared habitats with cattle and tended to increase their diurnal activities where cattle were present.All 3 study species exhibitedfine-scale spatial-temporal segregation to cattle.Leopards selectively preyed on calves over adult cattle and livestock depredation frequency was positively correlated with the detection rates of cattle and wild prey,but not that of leopard.Thesefindings not only show that through behavioral adaption large carnivores and their ungulate prey may persist under livestock disturbance,but also highlight how important proper livestock management is for conserving North Chinese leopards in this region.To enhance livestock management and mitigate human–leopard conflicts,we recommend specific actions,such as better guarding of free-ranging cattle or adoption of a captive farming system. | Mingzhang LIU Yiqing WANG Fan XIA Hongliang BU Yanlin LIU Xiaoli SHEN Sheng LI | 2023 | Integrative Zoology2023，18，1： | 0 |
