X1（Me O-TPD） is an inexpensive and easily synthesized π-conjugated molecule that has been used as a hole-transport material（HTM） in solid-state dye-sensitized solar cells（ssDSSCs）, achieving relatively high efficiency. In this paper, we characterize the physicochemical properties of 2,3-dichloro-5,6-dicyano-1,4-benzoquinone（DDQ） and show that it is a promising p-dopant in a spin-coating solution with X1 as the HTM. The doped ssDSSCs showed an increase in short-circuit current density from 5.38 mA cm-2 to7.39 mA cm-2, and their overall power conversion efficiency increased from 2.9% to 4.3%. Also, ssDSSCs with DDQ-doped X1 were more stable than the undoped samples, demonstrating that DDQ can act as a p-type dopant in X1 as an HTM for highly efficient, stable ssDSSCs.

作者： Yanjing Zheng xiuna wang Xiaoling Zhang Wei Li Gang Liu Shihua wang Xiufeng Yan Huixi Zou Wen-Bing Yin Zhejiang Provincial(Wenzhou) Key Lab for Water Environment and Marine Biological Resources Protection College of Life and Environmental Science Wenzhou University State Key Laboratory of Mycology Institute of Microbiology Chinese Academy of Sciences School of Life Sciences Fujian Agriculture and Forestry University College of Life Sciences University of Chinese Academy of Sciences

The COP9 signalosome(CSN) is a highly conserved multiprotein complex in all eukaryotes and involved in regulation of organism development. In filamentous fungi, several lines of evidence indicate that fungal development and secondary metabolism(SM) are mediated by the fifth subunit of CSN, called CsnE. Here we uncover a connection with CsnE and conidial formation as well as SM regulation in the plant endophytic fungus Pestalotiopsis fici. A homology search of the P. fici genome with CsnE, involved in sexual development and SM in Aspergillus nidulans, identified PfCsnE. Deletion of PfcsnE resulted in a mutant that stopped conidial production, but the conidia are recovered in a PfcsnE complemented strain. This indicates that PfCsnE is required for the formation of conidia. Secondary metabolite analysis demonstrated that the ΔPfcsnE strain produced more chloroisosulochrin, less ficiolide A production in comparison to wild type(WT). Transcriptome analysis of WT andΔPfcsnE strains indicated that PfcsnE impacts the expression levels of 8.37% of 14,797 annotated genes. Specifically, nine biosynthetic gene clusters(BGCs) were up-regulated and three BGCs were down-regulated by PfCsnE. Our results suggest that PfCsnE plays major roles in SM regulation and conidial development in P. fici.

以氩离子团簇为溅射源,对采用一步旋涂法制备的CH_(3)NH_(3)PbI_(3)钙钛矿薄膜进行溅射实验,通过XPS分析检测样品表面Pb元素的价态变化。结果表明,新制备的钙钛矿薄膜材料表面没有检测出Pb^(0),而经过团簇离子枪溅射的样品中部分Pb^(2+)还原成Pb^(0),证明了氩离子团簇刻蚀对钙钛矿材料具有破坏作用。一方面,溅射时间的增加以及团簇离子枪能量的增大均会加大钙钛矿材料的损伤程度;另一方面,离子枪团簇规模大小与溅射损伤程度呈近抛物线关系。因此,在进行此类样品表面清洁时,应尽量减小离子枪能量和溅射时间,选择较小或较大的团簇规模以减少对样品的损伤。该研究对于钙钛矿样品在进行XPS检测和数据分析时具有参考价值。

目的:了解中小学班主任抑郁状况潜类别特点及相关因素。方法:在12个省份抽取3255名中小学班主任,采用贝克抑郁量表(BDII)调查抑郁症状,采用潜类别分析方法和多因素logistic回归分别探讨抑郁状况的潜类别分布及相关因素。结果:存在高抑郁组(18.1%)、低抑郁组(40.1%)和无抑郁组(41.8%)3个潜在类别。多因素logistic回归分析显示,与无抑郁组相比,对写文章或做科研感到有压力(高抑郁组OR=1.31)、因科任老师配合差或专业能力差而感到有压力(低抑郁组OR=1.39)、对学校“将对学生的评估结果运用于教师的教学评定”的评价(高抑郁组OR=1.59、1.72;低抑郁组OR=1.57、1.53)是抑郁的危险因素;对“自己缺乏班主任工作有关的专门知识”持否定态度是保护性因素(高抑郁组OR=0.52、0.51;低抑郁组OR=0.73、0.47)。结论:中小学班主任的抑郁状况存在明显的分类特征,工作内容、评价指标和教学本职工作的偏离可能会增加抑郁风险。

在加快推进科研体制和输配电价改革形势下,探究电网科技项目优选与有效成本评估的综合方法,有利于扎实推进电网的高质量发展。在输配电价定价成本核定日趋严格趋势下,科研成本性支出作为输配电价定价成本中其他费用科目之一,也受到更为严格的监审,电网公司须在有限的科研成本性支出下追求更高的效率效益。本文从效率、效益视角,引入技术难度系数和工作当量,构建研发团队、科研产出、解决问题的效率和近期投入产出、远期潜在效益的效益指标;并基于变异系数法、层次分析法改进的逼近理想解法,构建电网科技项目优选决策模型,测算产出效率效益,评估有效成本性支出,为准许成本核定提供支撑。案例分析表明:该模型综合兼顾了科研体制改革要求的生产力转化效益以及电力体制改革要求的科研产出效率,可为输配电价改革下电网科技项目优选和公司其他费用的核定提供参考。
