| 2 | Utilizing 3D DOSY NMR in the characterization of organic compounds in coal chemical wastewater显示文摘Coal chemical wastewater(CCW)with the features of high toxicity and poor biodegradability is a big issue in environmental remediation,posing a great threat to aquatic ecosystems and to human beings.Such complex molecular mixtures are notoriously difficult to characterize without initial physical separation.Herein,we present the 3D diffusion ordered spectroscopy(DOSY)analysis for CCW using DOSY-COSY and DOSY-HSQC methods,the advantages of this strategy have been demonstrated in the analysis of mixtures of aliphatic oxygenates and aromatic compounds,before being implemented on a genuine CCW sample in this study.The results showed that 3D DOSY is a robust and reliable tool for providing superior resolution and virtual separation of complex pollutants,and can be used as a general approach for structural elucidation. | Hui Ma Christian M.Pedersen Qi Zhao Shiyu Jia Bin Yuan Xianglin Hou Yingxiong Wang | 2022 | Magnetic Resonance Letters2022，2，2： | 1 |
| 3 | Geographical vs. ecological diversification in Carex section Phacocystis (Cyperaceae): Patterns hidden behind a twisted taxonomy显示文摘Carex section Phacocystis(Cyperaceae)is one of the most diverse and taxonomically complex groups of sedges(between 116 and 147 species),with a worldwide distribution in a wide array of biomes.It has a very complicated taxonomic history,with numerous disagreements among different treatments.We studied the biogeography and niche evolution in a phylogenetic framework to unveil the relative contribution of geographical and ecological drivers to diversification of the group.We used a large species sampling of the section(82%of extant species)to build a phylogeny based on four DNA regions,constrained with a phylogenomic HybSeq tree and dated with six fossil calibrations.Our phylogenetic results recovered section Phacocystis s.s.(core Phacocystis)as sister to section Praelongae.Ancestral area reconstruction points toward the N Pacific as the cradle for the crown diversification of section Phacocystis during the Middle Miocene.Wide distributions were recurrently inferred across deep nodes.Large Northern Hemisphere lineages with geographical congruence were retrieved,pointing toward the importance of allopatric divergence at deep phylogenetic levels,whereas within-area speciation emerges as the predominant pattern at shallow phylogenetic level.The Southern Hemisphere(Neotropics,SW Pacific)was colonized several times from the Northern Hemisphere.The global expansion of Carex section Phacocystis did not entail major ecological changes along the inner branches of the phylogeny.Nevertheless,ecological differentiation seems to gain importance toward recent times. | Carmen Benitez-Benitez Santiago Martin-Bravo Charlotte S.Bjora Sebastian Gebauer Andrew L.Hipp Matthias H.Hoffmann Modesto Lucefio Tyril M.Pedersen Anton Reznicek Eric Roalson Polina Volkova Okihito Yano Daniel Spalink Pedro Jimenez-Mejias | 2021 | Journal of Systematics and Evolution2021，59，4： | 0 |
