The use of cover crops is a promising strategy for influencing the soil microbial consortium,which is essential for the delivery of multiple soil functions(i.e.,soil multifunctionality).Nonetheless,relatively little is known about the role of the soil microbial consortium in mediating soil multifunctionality under different cover crop amendments in dryland ***,we assessed the multifunctionality of soils subjected to four cover crop amendments(control,non-amended treatment;RD,radish monoculture;HV,hairy vetch monoculture;and RDHV,radish-hairy vetch mixture),and we investigated the contributions of soil microbial richness,network complexity,and ecological clusters to soil *** results demonstrated that cover crops whose chemical composition differed from that of the main plant crop promoted higher multifunctionality,and the radish-hairy vetch mixture rendered the highest *** obtained evidence that changes in soil microbial richness and network complexity triggered by the cover crops were associated with higher soil ***,specialized microbes in a key ecological cluster(ecological cluster 2)of the soil microbial network were particularly important for maintaining soil *** results highlight the importance of cover crop-induced variations in functionally important taxa for promoting the soil multifunctionality of dryland Ultisols.

别于宋元,在官创私办之下,明代中后期位于边缘海疆的海南书院迎来发展热潮,数量骤增、学制完善,追齐华夏中心地带书院的发展水平,呈现一体化、官学化、平民化及社团化特征。因创办经费来源、教学宗旨与属地层级分野,书院存在官私之分、考课式讲会式之别、府州县乡之异。又因岛内地理、历史要素不均衡,书院时空分布呈现,以嘉靖、万历两朝最盛,集中于以琼州府治为中心的北部几个州县治所。在明中叶科举与官学一体化影响下,海南书院的存在,不仅为官方认定的官学之辅,更补救官学流弊。在承担读书人的人文理想、社会责任与国家教育责任之外,作为明代“大一统”在边缘海疆文化塑造中的重要一环,海南书院在明中后期海南社会的具体历史情境中,其政治文化意蕴更为突出。

Annealing Effect of ZnO on the Performance of Inverted Organic Photovoltaic Devices

引用

Journal of Materials Science & Technology 2014年第2期30卷 197-202页

作者： wenjing qin Guojing Ding Xinrui Xu Liying Yang Shougen Yin Key Laboratory of Display Materials & Photoelectric Devices(Ministry of Education) and School of Materials Science &Engineering Tianjin University of Technology Tianjin Key Lab for Photoelectric Materials & Devices

ZnO nanoparticles films were prepared via sol-gel process and incorporated into inverted organic photovoltaic devices with a structure of ITO/ZnO/P3HT：PCBM/MoO3/Ag, in which ZnO film served as an electron selective layer. The effects of annealing temperature of ZnO film on the device performance were investigated. When the annealing temperature was 300℃, a well-arranged ZnO thin film was obtained, and the optimized device had doubled short circuit current density （Jsc） and seven-fold higher power conversion efficiency （PCE） compared to the devices without ZnO film. This improvement could be attributed to the enlarged interfacial area of ZnO/active layer and better energy band matching which causes an efficient electron extraction and a decreased interface energy barrier. At particularly high annealing temperature, dramatically increased sheet resistance of indium tin oxide （ITO） was found to cause PCE deterioration. Our finding indicates that it is highly important to investigate both morphology and electrical effects for understanding and optimizing organic photovoltaic （OPV） performance.

β-淀粉样蛋白(Aβ)被认为是介导阿尔茨海默病(AD)发生发展的关键因素。Aβ的生成与清除的失衡将导致脑内Aβ大量堆积而引起聚集,进而对神经元细胞造成损伤,产生认知障碍,引起痴呆症状。为有效治疗AD,近年来,开展了大量以Aβ为靶点的临床研究,包括抑制Aβ的生成、聚集,促进Aβ清除等策略,但相关研究屡屡受挫。该文通过检索近些年国内外文献,针对Aβ在AD发展过程中的生物学效应及其临床研究现状进行探讨与梳理,以期为Aβ的靶向治疗策略提供思路。

Enzymes are macromolecular biological catalysts which can accelerate chemical reactions in living organisms. Almost all the physiological metabolism activities in the cell need enzymes to sustain life via rapid catalysis. Currently, medical research has proved that abnormal enzyme activity is associated with numerous diseases, such as Parkinson’s disease(PD), Alzheimer’s disease(AD) and cancers. On the other hand, early diagnosis of those diseases is of great significance to improve the survival rate and cure *** the current diagnostic tools, two-photon fluorescent probes(TPFPs) are developing rapidly due to their unique advantages, such as higher spatial resolution, deeper imaging depth, and lower ***, the design and synthesis of two-photon(TP) small molecule enzymatic probes have broad prospects for early diagnosis and treatment of diseases. As of now, scientists have developed many TP small molecule enzymatic probes. This review aims to summarize the TP small molecule enzymatic probes and expound the reaction mechanism.

Nitroreductase（NTR） is a member of flavin-containing enzymes that exists widely in bacteria. Hypoxia,which is a characteristic of locally advanced solid tumors, resulting from an imbalance between oxygen consumption and supply, can result in NTR overexpression. Using either nicotinamide adenine dinucleotide（NADH） or nicotinamide adenine dinucleotide phosphate（NADPH） as a source of reducing equivalents, NTR can catalyze the reduction of nitroaromatic compounds to the corresponding *** on this reduction mechanism, NTR can be applied not only in the bioremediation and degradation of organic nitrogen compounds, but also in the development of NTR-targeted fluorescent probes to detect the hypoxic status of cancer cells. This review aims to provide a summary of the progress in fluorescent probes for NTR in recent years and elucidate the main fluorescent mechanisms that have been applied to design probes.
