| 1 | Bacterial succession in epiphytic biofilms and deciduous layer sediments during Hydrilla verticillata decay: A field investigation显示文摘Submersed macrophytes decay is an important natural process and has important role in mass and energy flow in aquatic ecosystems.However,little is known about the dynamical changes in nutrients release and bacterial community during submersed macrophyte decay in natural environment.In this study,a field observation was conducted in a wetland dominated with Hydrilla verticillata for 36 days.Increase of H2O2 and malondialdehyde(MDA)content and decrease of soluble proteins concentration were detected in leaves during H.verticillata decay.Meanwhile,ammonium-N,soluble microbial products(SMP)and TOC concentration increased in overlying water.According to bacterial 16 S r RNA Illumina sequencing analysis,the Shannon values were lower in epiphytic biofilms than deciduous layer sediments.The relative abundances of Proteobacteria,Cyanobacteria and Actinobacteria were higher in epiphytic biofilms than in deciduous layer sediments(P<0.05).Co-occurrence network analyses showed that a total of 578 and 845 pairs of correlations(|r|>0.6)were identified from 122 and 112 genera in epiphytic biofilms and deciduous layer sediments,respectively.According to co-occurrence patterns,eight hubs were mainly from phyla Proteobacteria,Acidobacteria and Parcubacteria in epiphytic biofilms;while 37 hubs from the 14 phyla(Proteobacteria,Bacteroidetes,Acidobacteria,Chloroflexi,et al.)were detected in deciduous layer sediments.Our results indicate that bacterial community in deciduous layer sediments was more susceptible than in epiphytic biofilms during decay process.These data highlight the role of microbial community in deciduous layer sediments on nutrients removal during H.verticillata decay and will provide useful information for wetland management. | Tingting Si Hezhou Chen Zheng Qiu Lisha Zhang Okugbe Ebiotubo Ohore Songhe Zhang | 2020 | Journal of Environmental Sciences2020，32，7： | 2 |
| 2 | 2D Materials Boost Advanced Zn Anodes:Principles,Advances,and Challenges显示文摘Aqueous zinc-ion battery(ZIB)featuring with high safety,low cost,environmentally friendly,and high energy density is one of the most promising systems for large-scale energy storage application.Despite extensive research progress made in developing high-performance cathodes,the Zn anode issues,such as Zn dendrites,corrosion,and hydrogen evolution,have been observed to shorten ZIB’s lifespan seriously,thus restricting their practical application.Engineering advanced Zn anodes based on two-dimensional(2D)materials are widely investigated to address these issues.With atomic thickness,2D materials possess ultrahigh specific surface area,much exposed active sites,superior mechanical strength and flexibility,and unique electrical properties,which confirm to be a promising alternative anode material for ZIBs.This review aims to boost rational design strategies of 2D materials for practical application of ZIB by combining the fundamental principle and research progress.Firstly,the fundamental principles of 2D materials against the drawbacks of Zn anode are introduced.Then,the designed strategies of several typical 2D materials for stable Zn anodes are comprehensively summarized.Finally,perspectives on the future development of advanced Zn anodes by taking advantage of these unique properties of 2D materials are proposed. | Songhe Zheng Wanyu Zhao Jianping Chen Xiaoli Zhao Zhenghui Pan Xiaowei Yang | 2023 | Nano-Micro Letters2023，15，4： | 0 |
