Efficient CH3NH3PbI3 Perovskite Solar Cells Based on Graphdiyne (GD)‐Modified P3HT Hole‐Transporting Material 下载免费PDF全文

Novel large π‐conjugated carbon material, graphdiyne (GD), as a dopant to poly(3‐hexylthiophene) (P3HT) hole‐transporting material (HTM) layer, is introduced into perovskite solar cells for the first time. Raman spectroscopy and ultraviolet photoelectron spectroscopy measurements reveal that relatively strong π–π stacking interaction occurs between GD particles and P3HT (so‐called P3HT/GD composite HTM), favorable for the hole transportation and improvement of the cell performance. On the other hand, some GD aggregates exhibit a scattering nature, and thus help to increase the light absorption of the perovskite solar cells in the long wavelength range. As high as 14.58% light‐to‐electricity conversion efficiency is achieved, superior to the pristine P3HT‐based devices. Additionally, the devices exhibit good stability and reproducibility. Time‐resolved photoluminescence decay measurements reveal that the P3HT/GD HTM can accelerate the hole extraction compared with pristine P3HT. 相似文献

An integrative proteome analysis of different seedling organs in tolerant and sensitive wheat cultivars under drought stress and recovery 下载免费PDF全文

Roots, leaves, and intermediate sections between roots and leaves (ISRL) of wheat seedlings show different physiological functions at the protein level. We performed the first integrative proteomic analysis of different tissues of the drought‐tolerant wheat cultivar Hanxuan 10 (HX‐10) and drought‐sensitive cultivar Chinese Spring (CS) during a simulated drought and recovery. Differentially expressed proteins (DEPs) in the roots (122), ISRLs (146), and leaves (163) showed significant changes in expression in response to drought stress and recovery. Numerous DEPs associated with cell defense and detoxifications were significantly regulated in roots and ISRLs, while in leaves, DEPs related to photosynthesis showed significant changes in expression. A significantly larger number of DEPs related to stress defense were upregulated in HX‐10 than in CS. Expression of six HSPs potentially related to drought tolerance was significantly upregulated under drought conditions, and these proteins were involved in a complex protein–protein interaction network. Further phosphorylation analysis showed that the phosphorylation levels of HSP60, HSP90, and HOP were upregulated in HX‐10 under drought stress. We present an overview of metabolic pathways in wheat seedlings based on abscisic acid signaling and important protein expression patterns. 相似文献

Zinc-finger antiviral protein (ZAP) is a host factor that specifically inhibits the replication of certain viruses, including HIV-1, Ebola virus, and Sindbis virus. ZAP binds directly to specific viral mRNAs and recruits cellular mRNA degradation machinery to degrade the target RNA. ZAP has also been suggested to repress translation of the target mRNA. In this study, we report that ZAP is phosphorylated by glycogen synthase kinase 3β (GSK3β). GSK3β sequentially phosphorylated Ser-270, Ser-266, Ser-262, and Ser-257 of rat ZAP. Inhibition of GSK3β by inhibitor SB216763 or down-regulation of GSK3β by RNAi reduced the antiviral activity of ZAP. These results indicate that phosphorylation of ZAP by GSK3β modulates ZAP activity. 相似文献

Porcine circovirus type 2 (PCV2) is the etiologic agent of porcine circovirus-associated disease. Here, we first report the complete genome sequence of PCV2 strain JSTZ, which was isolated from piglet stool samples and is highly prevalent in China. It will help in understanding the epidemiology and molecular characteristics of PCV2. 相似文献

The HIV-1 viral infectivity factor (Vif) protein is essential for viral replication. Vif recruits cellular ElonginB/C-Cullin5 E3 ubiquitin ligase to target the host antiviral protein APOBEC3G (A3G) for proteasomal degradation. In the absence of Vif, A3G is packaged into budding HIV-1 virions and introduces multiple mutations in the newly synthesized minus-strand viral DNA to restrict virus replication. Thus, the A3G-Vif-E3 complex represents an attractive target for development of novel anti-HIV drugs. In this study, we identified a potent small molecular compound (VEC-5) by virtual screening and validated its anti-Vif activity through biochemical analysis. We show that VEC-5 inhibits virus replication only in A3G-positive cells. Treatment with VEC-5 increased cellular A3G levels when Vif was coexpressed and enhanced A3G incorporation into HIV-1 virions to reduce viral infectivity. Coimmunoprecipitation and computational analysis further attributed the anti-Vif activity of VEC-5 to the inhibition of Vif from direct binding to the ElonginC protein. These findings support the notion that suppressing Vif function can liberate A3G to carry out its antiviral activity and demonstrate that regulation of the Vif-ElonginC interaction is a novel target for small-molecule inhibitors of HIV-1. 相似文献

Genome sequence of Corynebacterium glutamicum ATCC 14067, which provides insight into amino acid biosynthesis in coryneform bacteria 总被引:1,自引:0,他引:1
We report the genome sequence of Corynebacterium glutamicum ATCC 14067 (once named Brevibacterium flavum), which is useful for taxonomy research and further molecular breeding in amino acid production. Preliminary comparison with those of the reported coryneform strains revealed some notable differences that might be related to the difficulties in molecular manipulation. 相似文献

Pseudomonas aeruginosa XMG, isolated from soil, utilizes lactate. Here we present a 6.45-Mb assembly of its genome sequence. Besides the lactate utilization mechanism of the strain, the genome sequence may also provide other useful information related to P. aeruginosa, such as identifying genes involved in virulence, drug resistance, and aromatic catabolism. 相似文献
