Plasmonic nanostructures are capable of driving photocatalysis through absorbing photons in the visible region of the solar spectrum. Unfortunately, the short lifetime of plasmon‐induced hot carriers and sluggish surface chemical reactions significantly limit their photocatalytic efficiencies. Moreover, the thermodynamically favored excitation mechanism of plasmonic photocatalytic reactions is unclear. The mechanism of how the plasmonic catalyst could enhance the performance of chemical reaction and the limitation of localized surface plasmon resonance devices is proposed. In addition, a design is demonstrated through co‐catalyst decorated plasmonic nanoparticles Au/IrOX upon a semiconductor nanowire‐array TiO2 electrode that are able to considerably improve the lifetime of plasmon‐induced charge‐carriers and further facilitate the kinetics of chemical reaction. A thermodynamically favored excitation with improved kinetics of hot carriers is revealed through electrochemical studies and characterization of X‐ray absorption spectrum. This discovery provides an opportunity to efficiently manage hot carriers that are generated from metal nanostructures through surface plasmon effects for photocatalysis applications. 相似文献

Rice bacterial leaf blight, caused by Xanthomonas oryzae pv. oryzae [(Ishiyama) Swings et al. 1990] (Xoo), is a major rice disease of the second crop season in Taiwan. A total of 88 Xoo strains collected from 10 major rice cultivating areas in Taiwan from 1986, 1997, 2000, 2004, and 2011 were characterized by repetitive‐element PCR (REP‐PCR) fingerprinting and virulence analyses. Among the five genetic clusters identified by the pJEL1/pJEL2 (IS1112‐based) and REP1R‐Dt/REP2‐D [repetitive extragenic palindromic (REP)‐based] primer sets, clusters A, C and D contained Xoo strains from geographically distant regions, which suggests a high frequency of Xoo dispersal in Taiwan. The 88 Xoo strains were evaluated by inoculations on IRBB near‐isogenic lines and five Taiwan rice cultivars. A subset of 45 moderately or highly virulent strains were classified into 15 pathotypes by their compatible or incompatible reactions on IR24 and 12 IRBB near‐isogenic lines, each containing a single resistance gene. Analysis of molecular haplotypes and pathotypes revealed a partial relationship. IRBB5, IRBB21 and IRBB4 were incompatible with 96%, 96% and 73% of the strains, so xa5, Xa21 and Xa4 can recognize most of the Xoo strains in Taiwan and elicit resistance. In contrast, IRBB3 (Xa3), IRBB8 (xa8), IRBB10 (Xa10), IRBB11 (Xa11), IRBB13 (xa13) and IRBB14 (Xa14) were susceptible to almost all of the 45 Xoo strains. Inoculation trials revealed significant differences in the susceptibility of five Taiwan cultivars to Xoo (from high to low susceptibility: Taichung Sen 10 > IR24, Taichung Native 1 > Taichung 192, Taikeng 9, Tainan 11). This study provides useful information for resistance breeding and the development of disease management strategies against bacterial blight disease of rice. 相似文献

Asian minnows of the genus Zacco are dominant fish in various freshwater ecosystems. Two species, Zacco pachycephalus and Z. platypus, occur in Taiwan and are favourite targets for local sport anglers. The introduction of Zacco fish into nonindigenous habitats in Taiwan has become a conservation issue. We developed eight polymorphic microsatellites for Z. pachycephalus (average HE = 0.779) and these microsatellites were applicable to Z. platypus, which showed a comparable polymorphic level (average HE = 0.784). These loci can be used as genetic markers for identifying conservation units and studying population differentiation for both Zacco species. 相似文献

Peripheral artery disease (PAD) is a manifestation of systemic atherosclerosis and conveys a significant health burden globally. Critical limb ischaemia encompasses the most severe consequence of PAD. Our previous studies indicate that microRNA let‐7g prevents atherosclerosis and improves endothelial functions. This study aimed to investigate whether and how let‐7g therapy may improve blood flow to ischaemic limbs. The present study shows that let‐7g has multiple pro‐angiogenic effects on mouse ischaemic limb model and could be a potential therapeutic agent for PAD. Mice receiving intramuscular injection of let‐7g had more neovascularization, better local perfusion and increased recruitment of endothelial progenitor cells after hindlimb ischaemia. The therapeutic effects of let‐7g's on angiogenesis are mediated by multiple regulatory machinery. First, let‐7g increased expression of vascular endothelial growth factor‐A (VEGF‐A) and VEGF receptor‐2 (VEGFR‐2) through targeting their upstream regulators HIF‐3α and TP53. In addition, let‐7g affected the splicing factor SC35 which subsequently enhanced the alternative splicing of VEGF‐A from the anti‐angiogenic isoform VEGF‐A165b towards the pro‐angiogenic isoform VEGF‐A164a. The pleiotropic effects of let‐7g on angiogenesis imply that let‐7g may possess a therapeutic potential in ischaemic diseases. 相似文献

The order Hymenochaetales of white rot fungi contain some of the most aggressive wood decayers causing tree deaths around the world. Despite their ecological importance and the impact of diseases they cause, little is known about the evolution and transmission patterns of these pathogens. Here, we sequenced and undertook comparative genomic analyses of Hymenochaetales genomes using brown root rot fungus Phellinus noxius, wood‐decomposing fungus Phellinus lamaensis, laminated root rot fungus Phellinus sulphurascens and trunk pathogen Porodaedalea pini. Many gene families of lignin‐degrading enzymes were identified from these fungi, reflecting their ability as white rot fungi. Comparing against distant fungi highlighted the expansion of 1,3‐beta‐glucan synthases in P. noxius, which may account for its fast‐growing attribute. We identified 13 linkage groups conserved within Agaricomycetes, suggesting the evolution of stable karyotypes. We determined that P. noxius has a bipolar heterothallic mating system, with unusual highly expanded ~60 kb A locus as a result of accumulating gene transposition. We investigated the population genomics of 60 P. noxius isolates across multiple islands of the Asia Pacific region. Whole‐genome sequencing showed this multinucleate species contains abundant poly‐allelic single nucleotide polymorphisms with atypical allele frequencies. Different patterns of intra‐isolate polymorphism reflect mono‐/heterokaryotic states which are both prevalent in nature. We have shown two genetically separated lineages with one spanning across many islands despite the geographical barriers. Both populations possess extraordinary genetic diversity and show contrasting evolutionary scenarios. These results provide a framework to further investigate the genetic basis underlying the fitness and virulence of white rot fungi. 相似文献

The demand for high energy‐density, mass‐producible cathode materials has spurred the exploration of new material structures and compositions. Lithium‐excess, cation‐disordered rocksalt (DRX) materials are a new class of transition metal oxides that display high capacity and environmental friendly composition. These materials achieve their high capacities partially through oxygen redox, which leads to oxygen loss and detrimental reactivity with the electrolyte. It has previously been shown that oxygen loss can be suppressed by partial substitution of the lattice oxygen for fluorine, but the explicit mechanism behind this effect remains unknown. In this work, differential electrochemical mass spectrometry (DEMS) and titration mass spectrometry are used to quantify the primary electrochemical reactions occurring during the first cycle in DRX materials. Comparing a DRX oxide and a DRX oxyfluoride, it is shown that fluorination limits oxygen redox and suppresses oxygen loss. Additionally, DEMS is coupled with fluoride‐scavenging to demonstrate that small amounts of fluorine dissolve from DRX oxyfluorides during the first cycle. Finally, these techniques are extended over the first several cycles, demonstrating that CO2 evolution persists and fluoride dissolution continues to a diminishing extent during the first few cycles. These findings motivate surface modifications to control interfacial reactivity and improve long‐term cycling. 相似文献
