Ammonia is one of the most essential chemicals in the modern society but its production still heavily relies on energy-consuming Haber-Bosch *** photocatalytic reduction of nitrogen with water for ammonia production has attracted much attention recently due to its synthesis under mild conditions at room temperature and atmospheric pressure using ***,we report a high-performance Au/MIL-100(Cr)photocatalyst,comprising MIL-100(Cr)and Au nanoparticles in photocatalytic nitrogen reduction to ammonia at ambient conditions under visible light *** optimized photocatalyst(i.e.,0.10Au/MIL-100(Cr))achieved the excellent ammonia production rate with 39.9μg g_(cat)^(-1) h^(-1) compared with pure MIL-100(Cr)(2.73μg gcat^(-1) h^(-1)),which was nearly 15 times that on pure MIL-100(Cr).The remarkable activity could be attributed to the adsorption-plasmonic synergistic effects in which the MIL-100(Cr)and Au are responsible to the strong trapping and adsorption of N2 molecules and photo-induced plasmonic hot electrons activating and decomposing the N2 molecules,*** study might provide a new strategy for designing an efficient plasmonic photocatalyst to improve the photocatalytic performance of N2 fixation under visible light irradiation.

旨在对产蛋间隔前期母鸽卵泡颗粒细胞(GC)层进行高通量测序,筛选出与鸽卵泡发育和选择相关的关键基因。本研究选择了80对12月龄产蛋规律、体重相近的白羽王鸽为研究对象,在产蛋间隔第1天(li1)和第3天(li3)分别选择3只母鸽,采集F1和SF1卵泡GC层,并利用RNA-seq进行转录组分析,筛选L1F1/L1SF1、L3F1/L3SF1、L1F1/L3F1和L1SF1/L3SF1组,4组间差异表达基因(DEGs),对DEGs进行GO功能注释和KEGG通路富集分析,通过STRING数据库进行蛋白质互作(PPI)网络分析并使用Cytoscape软件进行可视化处理筛选关键基因,各组随机选择5个DEGs进行RT-qPCR验证转录组的可靠性。在4组比对中分别获得77、2736、5698和3864个DEGs。GO分析显示,4组DEGs都主要富集的GO条目为细胞过程、细胞解剖实体和连接。KEGG通路富集分析显示,L1F1/L1SF1组和L3F1/L3SF1组DEGs均显著富集在类固醇激素生物合成和卵巢类固醇合成等信号通路,L1F1/L3F1组和L1SF1/L3SF1组DEGs均显著富集在糖胺聚糖降解、突触囊泡周期和氧化磷酸化等信号通路。进一步地,进行PPI网络分析并筛选与卵泡发育和选择密切相关的DEGs。各组随机选择5个DEGs进行RT-qPCR验证,表达趋势与测序结果一致。本研究利用RNA-seq技术筛选到与鸽卵泡发育和选择相关的关键基因——EEF2、DDX5、PLK2、IGF 2R、LHCGR、HSD 3B1、CYP 19A1和StAR,为进一步探究鸽卵泡发育和选择的分子调控机制提供了理论依据。

作者： YU li-qiong HUANG Ru-dan chi ying-nan HU Chang-wen Department of Chemistry Beijing Institute of Technology Beijing 100081 P R. China

A novel three-dimensional（3D） supramolecular architecture, {[Nd（OH-BDC）（OH-HBDC）（H2O）2]·2HaO）n（1）（OH-H2BDC=5-hydroxyisophthalic acid）, which was formed through hydrogen bonds and π-π stacking between two-dimensional（2D） layers, was hydrothermally synthesized and characterized by single-crystal X-ray diffraction. Windmill building blocks, which consist of two nine-coordinated metal centers and four OH-H2BDC groups are connected through two carboxyl groups, to lead to a one-dimensional infinite inorganic chain（… M--O--C--O--M…） along the [100] direction. An observed intense blue luminescence with an emission band peaked at 390 nm for compound 1 may results from ligand-to-metal charge transfer（LMCT）. Variable-temperature magnetic susceptibility of compound 1 was investigated and the value was deviated from the Curie-Weiss law.

推广和普及国家通用语言是铸牢中华民族共同体意识的重要途径。基于中国民族地区经济社会住户调查和中国综合社会调查数据的研究发现:各民族人口的国家通用语言能力均呈上升趋势,并且民族间的语言能力差距缩小;国家通用语言能力受个体、家庭、学校和社交网络的综合影响,受教育程度、居住安排、家庭经济状况、寄宿、流动经历、互联网使用是正向预测因素,同胞数量和“汉少”双语授课是负向预测因素;民族身份与个体的国家通用语言能力紧密关联,父代族际通婚家庭子女比非族际通婚家庭子女的普通话听说能力和汉字读写能力更好。全面加强国家通用语言教育,要在民族地区积极推广普通话和汉字,充分利用个体语言发展的关键期,保障各民族家庭子女掌握交流互通的语言工具。
