Nowadays, the soar of photovoltaic performance of perovskite solar cells has set off a fever in the study of metal halide perovskite materials. The excellent optoelectronic properties and defect tolerance feature allow metal halide perovskite to be employed in a wide variety of applications. This article provides a holistic review over the current progress and future prospects of metal halide perovskite materials in representative promising applications, including traditional optoelectronic devices(solar cells, light-emitting diodes, photodetectors, lasers), and cutting-edge technologies in terms of neuromorphic devices(artificial synapses and memristors) and pressure-induced emission. This review highlights the fundamentals, the current progress and the remaining challenges for each application, aiming to provide a comprehensive overview of the development status and a navigation of future research for metal halide perovskite materials and devices.

Journal of Forestry Research 2005年第2期16卷 125-131页

作者： XIEFu-ju XIAODu-ning lixiu-zhen wangXu-gao SHIBao-dong InstituteofAppliedEcology ChineseAcademyofSciencesShenyang110016P.R.China／／GraduatedSchoolofChineseAcademyofSciencesBeijing100039P.R.China InstituteofAppliedEcology ChineseAcademyofSciencesShenyang110016P.R.China

The restoration of forest landscape has drawn much attention since thecatastrophic fire took place on the northern slope of Great Xing'an Mountains in 1987. Forest canopydensity, which has close relation to forest productivity, was selected as a key factor to find howmuch the forest quality was changed 13 years after fire, and how fire severity, regeneration way andterrain factors influenced the restoration of forest canopy density, based on forest inventory datain China, and using Kendall Bivariate Correlation Analysis, and Distances Correlation Analysis. Theresults showed that fire severity which was inversely correlated with forest canopy density gradewas an initial factor among all that selected. Regeneration way which did not remarkably affectforest canopy density restoration in short period, may shorten the cycle of forest succession andpromote the forest productivity of conophorium in the future. Among the three terrain factors, theeffect of slope was the strongest, the position on slope was the second and the aspect was the last.

目的研究添加石墨烯纳米颗粒后润滑油的黏度变化规律,并确定超声时间等因素对石墨烯润滑油黏度变化的影响。方法通过“两步法”制备石墨烯润滑油纳米流体,并采用XRD和静置观察等技术对石墨烯结构及油基纳米流体的分散稳定性进行表征分析;通过旋转黏度计检测超声时间、石墨烯纳米颗粒质量分数及温度等因素对石墨烯润滑油黏度的影响。结果适当的超声时间有助于降低石墨烯团聚体尺寸和纳米流体黏度;石墨烯纳米流体的黏度随质量分数的增加并非总是线性增加,主要归因于石墨烯的特殊二维结构造成层间摩擦和剪切层数量的减少;石墨烯纳米流体的黏度与温度具有强相关性,所有制备的样品黏度都随温度的升高而降低。结论对于较高质量分数的石墨烯纳米流体,需要更高的超声时间及功率来对石墨烯团聚体进行分散;石墨烯的特殊层结构影响了纳米流体黏度的变化规律;流体黏度与温度的变化仍是负相关的。

目的:探讨自我效能感和积极应对方式在护士逆境商与工作投入之间的链式中介作用,以期为护理管理者促进工作投入提供理论参考。方法:采用便利抽样法于2021年12月选取陕西省4所三级甲等医院的512名护士,采用一般资料调查问卷、逆境商量表、一般自我效能感量表、简易应对方式量表和工作投入量表简化版对其进行横断面调研。结果:护士逆境商、自我效能感、积极应对方式和工作投入的总分分别为132.00(120.00,139.00)、27.00(23.00,29.00)、24.00(20.00,25.00)、27.00(25.00,35.00)分。护士逆境商、自我效能感、积极应对方式与工作投入均呈显著正相关(r值为0.523~0.614,均P<0.01)。自我效能感或积极应对方式的独立中介效应和两者的链式中介效应分别占总效应的23.6%、40.9%、15.9%。结论:护士逆境商不仅直接影响工作投入,还通过自我效能感、积极应对方式间接影响工作投入,研究提示管理者应关注护士自我效能感和积极应对方式的提升,促进护士的工作投入。

Since 1995,bulk-heterojunction organic solar cells consisting of one or two organic donors and one or two organic acceptors have been fighting for high power conversion efficiencies(PCEs)and good stability[1].Until recent years,this next-generation photovoltaic technology starts to offer decent PCEs,shedding the light on commercialization,and attracting great attention again[2-14].Compared w让h the continuously emerging highperformance nonfullerene acceptors,high-performance donors are rare.
