Covalent organic frameworks(COFs)are a new kind of crystalline porous materials composed of organic molecules connected by covalent bonds,processes the characteristics of low density,large specific surface area,adjustable pore size and structure,and easy to functionalize,which have been widely used in the field of membrane separation technology.Recently,there are more and more researches focusing on the preparation methods,separation application,and mechanism of COF membranes,which need to be further summarized and compared.In this review,we primarily summarized several conventional preparation methods,such as two-phase interfacial polymerization,in-situ growth on substrate,unidirectional diffusion method,layer-by-layer assembly method,mixed matrix membranes,and so on.The advantages and disadvantages of each method are briefly summarized.The application potential of COF membrane in liquid separation are introduced from four aspects:dyeing wastewater treatment,heavy metal removal,seawater desalination and oil-water separation.Then,the mechanisms including pore structure,hydrophilic/hydrophobic,electrostatic repulsion/attraction and Donnan effect are introduced.For the efficient removal of different kind of pollutions,researchers can select different ligands to construct membranes with specific pore size,hydrophily,salt or organic rejection ability and functional group.The ideas for the design and preparation of COF membranes are introduced.Finally,the future direction and challenges of the next generation of COF membranes in the field of separation are prospected.

The coronavirus disease 2019(COVID-19)pandemic has been looming globally for three years,yet the diagnostic and treatment methods for COVID-19 are still undergoing extensive exploration,which holds paramount importance in mitigating future epidemics.Host non-coding RNAs(ncRNAs)display aberrations in the context of COVID-19.Specifically,microRNAs(miRNAs),long non-coding RNAs(lncRNAs),and circular RNAs(circRNAs)exhibit a close association with viral infection and disease progression.In this comprehensive review,an overview was presented of the expression profiles of host ncRNAs following SARS-CoV-2 invasion and of the potential functions in COVID-19 development,encompassing viral invasion,replication,immune response,and multiorgan deficits which include respiratory system,cardiac system,central nervous system,peripheral nervous system as well as long COVID.Furthermore,we provide an overview of several promising host ncRNA biomarkers for diverse clinical scenarios related to COVID-19,such as stratification biomarkers,prognostic biomarkers,and predictive biomarkers for treatment response.In addition,we also discuss the therapeutic potential of ncRNAs for COVID-19,presenting ncRNA-based strategies to facilitate the development of novel treatments.Through an in-depth analysis of the interplay between ncRNA and COVID-19 combined with our bioinformatic analysis,we hope to offer valuable insights into the stratification,prognosis,and treatment of COVID-19.

火山岩油气藏是油气勘探的重要领域之一。苏北盆地溱潼凹陷侵入岩分布广泛,油气显示活跃,已成为我国东部陆相盆地油气深化勘探和规模增储的重要领域,具备良好的勘探前景。然而,目前针对火山岩对泥页岩围岩储层及其成藏影响的研究较为缺乏,泥页岩围岩变质带能否作为勘探重点领域有待深入评价。为了推动苏北盆地侵入岩围岩变质带新类型油藏勘探,以溱潼凹陷阜二段侵入岩围岩变质带为研究对象,综合岩心、薄片、全岩、测井等资料,系统揭示了泥页岩变质带储层特征,明确了岩浆侵入对阜二段变质带油气成藏的贡献。研究表明,溱潼凹陷阜二段泥页岩受岩浆侵入影响,泥页岩围岩发生蚀变形成环状变质带储层,岩浆的侵入具有明显“增储作用”;变质带储层发育孔隙、裂缝两类储集空间,储层发育程度受侵入岩厚度及烘烤强度控制,岩浆的侵入具有“催熟作用”,同等深度下泥页岩Ro可增加0.4%~0.5%;阜宁组侵入岩形成于吴堡期—三垛期,火成岩侵入形成环状变质带的时间早于油气充注期,具有良好的成藏匹配关系。受岩浆侵入、侵入岩空间分布以及源储匹配关系控制,溱潼凹陷阜二段侵入岩围岩变质带具有源储一体、近源富集的特征,是规模增储的新阵地。

Nypa fruticans(Wurmb),a mangrove palm species with origins dating back to the Late Cretaceous period,is a unique species for investigating long-term adaptation strategies to intertidal environments and the early evolution of palms.Here,we present a chromosome-level genome sequence and assembly for N.fruticans.We integrated the genomes of N.fruticans and other palm family members for a comparative genomic analysis,which confirmed that the common ancestor of all palms experienced a whole-genome duplication event around 89 million years ago,shaping the distinctive characteristics observed in this clade.We also inferred a low mutation rate for the N.fruticans genome,which underwent strong purifying selection and evolved slowly,thus contributing to its stability over a long evolutionary period.Moreover,ancient duplicates were preferentially retained,with critical genes having experienced positive selection,enhancing waterlogging tolerance in N.fruticans.Furthermore,we discovered that the pseudogenization of Early Methionine-labelled 1(EM1)and EM6 in N.fruticans underly its crypto-vivipary characteristics,reflecting its intertidal adaptation.Our study provides valuable genomic insights into the evolutionary history,genome stability,and adaptive evolution of the mangrove palm.Our results also shed light on the long-term adaptation of this species and contribute to our understanding of the evolutionary dynamics in the palm family.

Influence of Rain on Tetrachloroethylene's Multiphase Migration in Soil

Journal of Earth Science 2015年第3期26卷 453-460页

作者： Yong Qian Jingli Shao Zhaoji Zhang Yuhong Fei Chunxiao Wang Xiangxiang Cui suhua meng School of Water Resources & Environment China University of Geosciences The Institute of Hydrogeology and Environmental Geology Chinese Academy of Geological Sciences Hebei Key Laboratory of Groundwater Remediation

For the increasingly serious soil and groundwater pollution by volatile organic compounds, tetrachloroethylene（PCE） was selected as the research object in this study. With the in-situ soil column physical simulation experiments, migration law of PCE in soil under rain conditions was studied by monitoring precipitation and soil parameter as well as sampling and analyzing soil and soil gas, and influence of rain on the multiphase migration process of PCE was preliminarily discussed. Research shows that migrations of PCE and soil moisture were not synchronous, and the rate of the former was speeded up by the latter caused by rain. Preliminary analysis indicates that migration of volatile chlorohydrocarbon in soil was not only driven by soil moisture, but also controlled by the nature of volatility of their own, that is to say, volatilization into gas phase was an important way of migrating and diffusing in pore medium, and the rate of migration and diffusion of gaseous PCE was faster than that of solid, resulting in more abroad distribution of gas phase than that in solid phase.

Spatiotemporal Evolution Characteristics Study on the Precipitation Infiltration Recharge over the Past 50 Years in the North China Plain

引用

Journal of Earth Science 2015年第3期26卷 416-424页

作者： suhua meng Jin Liu Zhaoji Zhang Ting Lei Yong Qian Yasong Li Yuhong Fei Institute of Hydrogeology and Environmental Geology Chinese Academy of Geological Sciences

The spatiotemporal evolution characteristics of precipitation infiltration recharge during the past 50 years are discussed in this paper. This research is significant for groundwater resource rational utilization. The distribution of precipitation infiltration recharge coefficients in the 1960 s, 1980 s, and 2000 s can be obtained using unsaturated zone lithology and depth to water table at different times. The amount of precipitation infiltration recharge in the 1960 s, 1980 s, and 2000 s can be calculated using precipitation infiltration recharge coefficients and precipitation data from the Ministry of Water Resources of China. Results show that the change in the precipitation infiltration recharge coefficient is closely related to the water table decrease. From the 1960 s to the 1980 s, the precipitation infiltration recharge coefficient clearly increased in all units. From the 1980 s to the 2000 s, the value slightly increased in the ancient Yellow River alluvial-proluvial and eastern alluvial-marine plains and slightly decreased in the piedmont alluvial-proluvial and central alluvial-lacustrine plains. The piedmont alluvial-proluvial and ancient Yellow River alluvial-proluvial plains exhibited a large precipitation infiltration recharge coefficient for the coarse lithology. The amounts of precipitation infiltration recharges were 16.23×109（1960s）, 19.11×109（1980s）, and 19.42×109 m3/a（2000s）. The amount of precipitation infiltration recharge increased from the 1960 s to the 1980 s then decreased from the 1980 s to the 2000 s in the piedmont alluvial-proluvial and the central alluvial-lacustrine plains. However, this value increased from the 1960 s to the 2000 s in the ancient Yellow River alluvial-proluvial and eastern alluvial-marine plains.

“数据二十条”在表述数据产权“三权分置”时分别使用了“数据资源”“数据”“数据产品”三项表达来称谓“三权”的客体,从政策上肯认并确立了数据产权的客体对象。从法律视角审视,前述三项政策表达仍需经由学理阐释来论证其在法律上的定位及其相互关系,使之成为具有规范性的法律表达。“三权分置”路径下,“数据”的核心特征应包括信息属性、物理属性和集合属性,并在数据生产和流通使用的“价值链”上延展形成“数据资源”—“数据集合”—“数据产品”的类型层级。在分级分类构建原则下,作为产权客体的“数据”还可在横向上形成以公共数据与企业数据为一级子类型、公用/私用公共数据与公开/不公开企业数据为二级子类型的类型谱系。由此,便可在“三权分置”路径下阐明作为产权客体的数据的规范属性与类型谱系,为数据产权“三权分置”的法律化奠定基础和前提。

[目的]坡度和坡长作为重要的地形因子,其计算的准确性直接影响坡面土壤侵蚀模型的评价精度。高分7号卫星的高精度高程测量能力在地形因子的准确提取上具有较大潜力,期望能将其利用到坡度和坡长提取之中,实现对地形的准确表达。这需要对利用高分7号卫星DEM提取坡度坡长的结果进行精度评价。[方法]利用地形因子(LS)计算工具,对陕西省吴堡县4个小流域高分7号卫星、1∶10000地形图、激光雷达影像生成的DEM进行坡度、坡长的提取。采用相关系数(r)、相对偏差和绝对偏差作为评价指标,评价高分7号提取地形因子的精度。[结果]与激光雷达和1∶10000地形图的坡度和坡长相比,高分7号提取的流域平均坡度偏低7.50%~9.02%,坡长偏大1.83%~19.35%,但坡长和坡度分级的面积比例并不存在显著差异;高分7号提取的坡度结果偏差(16.46%~44.26%)明显小于坡长的偏差(75.25%~140.87%);高分7号所提取的坡度坡长在沟间地上的相对偏差(坡度15.48%~56.63%,坡长50.02%~130.79%)明显低于沟谷地(坡度21.28%~63.61%,坡长93.01%~192.51%)。[结论]利用高分7号DEM提取坡度坡长时,对于获取坡长坡度面积分级和对指定点的坡度提取时是可行的,而对于指定点的坡长提取时则结果不够可靠,在研究流域中坡长坡度的空间分布上具有较大优势,而提取具体某一位置处的坡长坡度时的优势则不明显。
