| 1 | Surface Active Sites on Co_(3)O_(4) Nanobelt and Nanocube Model Catalysts for CO Oxidation显示文摘CO oxidation has been performed on Co_(3)O_(4) nanobelts and nanocubes as model catalysts.The Co_(3)O_(4) nanobelts which have a predominance of exposed{011}planes are more active than Co_(3)O_(4) nanocubes with exposed{001}planes.Temperature programmed reduction of CO shows that Co_(3)O_(4) nanobelts have stronger reducing properties than Co_(3)O_(4) nanocubes.The essence of shape and crystal plane effect is revealed by the fact that turnover frequency of Co3+sites of{011}planes on Co_(3)O_(4) nanobelts is far higher than that of{001}planes on Co_(3)O_(4) nanocubes. | Linhua Hu Keqiang Sun Qing Peng Boqing Xu Yadong Li | 2010 | Nano Research2010，3，5： | 21 |
| 2 | Geochemical characteristics and geological significance of the Neoproterozoic carbonates from northern Anhui Province, China显示文摘Petrographical and geochemical studies were carried out of the Neoproterozoic carbonates from northern Anhui Province, China. These carbonates can be subdivided into two types, including purified limestone (PL) and mixed limestone and siliclastic rocks (MLS). PLs are low in Si, Al, Zr and total REE but high in CaO compared with MLSs. Correlations between Zr, Fe2O3, P2O5 and total REE are also less remarkable, indicating that they were not obviously contaminated by continental materials but directly precipitated from seawater. So they can be used for the inversion of paleo-seawater REE patterns. The inversed results indicated that the REE pattern of Neoproterozoic seawater was similar to that of the modern seawater except for the lack of Ce depletion, which was probably affected by the reduced hydrothermal solution. In combination with previous studies, the geochemical trending of these carbonatic samples towards the continental arc in the La- Th-Sc and Th-Sc-Zr/10 diagrams is interpreted as the contamination of arc volcanism. The tectonic background of the southern margin of the North China Craton in the Neoproterozoic was probably related to the Grenville orogeny during the convergence of the Rodinia supercontinent, rather than an intra-plate environment. | SUN Linhua GUI Herong CHEN Song MA Yanping HE Zhenyu | 2011 | Chinese Journal Of Geochemistry2011，30，1： | 9 |
| 3 | Micelle or polymersome formation by PCL-PEG-PCL copolymers as drug delivery systems显示文摘Polye-caprolactone)-b-poly(ethylene glycol)-b-poly(e-caprolactone)(PCL-b-PEG-b-PCL,PCEC) triblock copolymers have been widely investigated in last several decades.Here,by altering the weight ratio of monomers in ring-opening polymerization,a series of PCEC triblock copolymers with varying hydrophobicity were synthesized,which were characterized by FTIR,1 H NMR,GPC and DSC.When PCEC copolymers with different weight ratios of PCL/PEG were dispersed in different aqueous solutions,they could self-assemble and form two distinctive nanoparticular structures:micelles or polymersomes.We then chose paclitaxel(PTX) as the model drug and encapsulate PTX into PCEC polymeric micelles and polymersomes.The physicochemical characterizations of the nanoparticles such as morphology,the size and distribution,zeta potential,drug loading content,and encapsulation efficiency were also performed.Our results showed that polymeric micelles or polymersomes from PCEC both displayed narrow size distributions and could achieve high drug loading efficiencies.In vitro cellular uptake results suggested that Nile Red loaded polymeric micelles or polymersomes displayed more internalization after 24 h incubation than those after 4 h incubation.These findings suggest that polymeric micelles and polymersomes based on PCL-b-PEG-b-PCL copolymers have great potential to effectively delivery hydrophobic drugs. | Chunyan Hu Zhuo Chen Shengjie Wu Yanfeng Han Hai Wang Hongfan Sun Deling Kong Xigang Leng Chun Wang Linhua Zhang Dunwan Zhu | 2017 | Chinese Chemical Letters2017，28，9： | 4 |
| 4 | Geochemistry of sandstones from the Neoproterozoic Jinshanzhai Formation in northern Anhui Province, China: Provenance, weathering and tectonic setting显示文摘Sandstones from the Neoproterozoic Jinshanzhai Formation in northern Anhui Province, China, were analyzed for major oxides and trace elements to infer their provenance, the intensity of paleo-weathering of their source rocks and the depositional tectonic setting. Diagrams of (SiO2/20)-(Na2O+K2O)-(MgO+TiO2+FeO*), TiO2-Ni, Th-Hf-Co, Hf-La/Th and some ratios of elements indicate that felsic rocks constitute the source rocks in the provenance. The values of Chemical Index of Alteration (CIA) are low, which are considered to be affected by K-metasomatism. Whereas the high CIW (Chemical Index of Weathering) values indicate intensive weathering of the source material. Plots of sandstones on bivariate and triangle discriminant diagrams, as well as ICV (Index of Compositional Variation) values revealed that they were deposited on a passive continental margin or in an intra-plate basin. Our recent study, in combination with previous studies and the research progress of the Rodinia super continent, demonstrated that the convergence and extension of the Rodinia super continent were preserved by twice extension as expressed by petrological variation of the southeastern margin of the North China Craton (NCC) during the Neoproterozoic. | SUN Linhua GUI Herong CHEN Song | 2013 | Chinese Journal Of Geochemistry2013，32，1： | 3 |
| 5 | Phylogenomic Insights into Deep Phylogeny of Angiosperms Based on Broad Nuclear Gene Sampling显示文摘Angiosperms(flowering plants)are the most diverse and species-rich group of plants.The vast majority(99.95%)of angiosperms form a clade called Mesangiospermae,which is subdivided into five major groups:eudicots,monocots,magnoliids,Chloranthales,and Ceratophyllales.The relationships among these Mesangiospermae groups have been the subject of long debate.In this study,we assembled a phylogenomic dataset of 1594 genes from 151 angiosperm taxa,including representatives of all five lineages,to investigate the phylogeny of major angiosperm lineages under both coalescent-and concatenationbased methods.We dissected the phylogenetic signal and found that more than half of the genes lack phylogenetic information for the backbone of angiosperm phylogeny.We further removed the genes with weak phylogenetic signal and showed that eudicots,Ceratophyllales,and Chloranthales form a clade,with magnoliids and monocots being the next successive sister lineages.Similar frequencies of gene tree conflict are suggestive of incomplete lineage sorting along the backbone of the angiosperm phylogeny.Our analyses suggest that a fully bifurcating species tree may not be the best way to represent the early radiation of angiosperms.Meanwhile,we inferred that the crown-group angiosperms originated approximately between 255.1 and 222.2 million years ago,and Mesangiospermae diversified into the five extant groups in a short time span(27 million years)at the Early to Late Jurassic. | Lingxiao Yang Danyan Su Xin Chang Charles SPFoster Linhua Sun Chien-Hsun Huang Xiaofan Zhou Liping Zeng Hong Ma Bojian Zhong | 2020 | Plant Communications2020，1，2： | 2 |
| 6 | Rare earth element geochemistry of groundwater from a deep seated sandstone aquifer,northern Anhui province,China显示文摘Deep coal mines in northern Anhui province,China,provide opportunities for tracing the distribution and fractionation of rare earth elements(REEs) in deep seated environments.Major ions,as well as REE concentrations were measured in groundwater from a sandstone aquifer located between-400 and-280 m.Our results indicate that this groundwater consists of Cl HCO3-Na or Cl CO3-Na water types with warm temperature(30.1-31.4 °C),circumneutral pH(7.27-8.61) and high levels of total dissolved solids(TDS = 1306-2165 mg/L).Concentrations of REEs in groundwater are high as expressed by their Nd concentrations(0.0086-0.018 lg/L).Except for weak heavy REEs(HREE) enrichment relative to light REEs(LREE),the similarity of REE distribution patterns between groundwater and aquifer rock indicate that enrichment of REEs is considered to be controlled by aquifer rock,as well as by their minerals,whereas the fractionation of REEs is controlled by HREE enriched minerals and,to a lesser extent,by inorganic REE complexes.Ce anomalies normalized to Post Archean Average Shale(PAAS) and aquifer rock are weak,which probably reflect the contribution of reduced conditions in combination with pH,rather than a signature of aquifer rock. | Gui Herong Sun Linhua Chen Luwang Chen Song | 2011 | Mining Science and Technology2011，21，4： | 2 |

| 9 | 8 Å structure of the outer rings of the Xenopus laevis nuclear pore complex obtained by cryo-EM and AI显示文摘The nuclear pore complex(NPC),one of the largest protein complexes in eukaryotes,serves as a physical gate to regulate nucleocytoplasmic transport.Here,we determined the 8Åresolution cryo-electron microscopic(cryo-EM)structure of the outer rings containing nuclear ring(NR)and cytoplasmic ring(CR)from the Xenopus laevis NPC,with local resolutions reaching 4.9Å.With the aid of AlphaFold2,we managed to build a pseudoatomic model of the outer rings,including the Y complexes and flanking components.In this most comprehensive and accurate model of outer rings to date,the almost complete Y complex structure exhibits much tighter interaction in the hub region.In addition to two copies of Y complexes,each asymmetric subunit in CR contains five copies of Nup358,two copies of the Nup214 complex,two copies of Nup205 and one copy of newly identified Nup93,while that in NR contains one copy of Nup205,one copy of ELYS and one copy of Nup93.These in-depth structural features represent a great advance in understanding the assembly of NPCs. | Linhua Tai Yun Zhu He Ren Xiaojun Huang Chuanmao Zhang Fei Sun | 2022 | Protein & Cell2022，13，10： | 1 |

| 11 | An efficient preparation of porous polymeric microspheres by solvent evaporation in foam phase显示文摘This paper reports an efficient method of preparing porous polymeric microspheres by solvent evaporation in foam phase,in which phase separation between polymer and porogen occurs in foam phase instead of that in water phase by using the traditional solvent eva poration method.The method provides outstanding features,including being time-saving,of high-yield and able for continuous production,in which formation of porous polymeric microspheres finished within 3 min with a high production yield up to approximate 95 wt% and the process was able to be developed into a continuous process for production of porous polymeric microspheres.It was also universal to non-crosslinked polymers since the method is a development on the traditional emulsion solvent evaporation method.The new method is efficient and can be used potentially on the industrial scale for continuous production of porous polymeric microsphere s. | Yang Yu Guiying Li Wanqing Han Linhua Zhu Tian Si HongWang Yanlin Sun Yanping He | 2021 | Chinese Journal of Chemical Engineering2021，34，1： | 1 |
| 12 | Conserved H3K27me3-associated chromatin looping mediates physical interactions of gene clusters in plants显示文摘Higher-order chromatin organization is essential for transcriptional regulation,genome stability maintenance,and other genome functions.Increasing evidence has revealed significant differences in 3D chromatin organization between plants and animals.However,the extent,pattern,and rules of chromatin organization in plants are still unclear.In this study,we systematically identified and characterized long-range chromatin loops in the Arabidopsis 3D genome.We identified hundreds of long-range cis chromatin loops and found their anchor regions are closely associated with H3K27me3 epigenetic modifications.Furthermore,we demonstrated that these chromatin loops are dependent on Polycomb group(PcG)proteins,suggesting that the Polycomb repressive complex2(PRC2)complex is essential for establishing and maintaining these novel loops.Although most of these PcG-medicated chromatin loops are stable,many of these loops are tissue-specific or dynamically regulated by different treatments.Interestingly,tandemly arrayed gene clusters and metabolic gene clusters are enriched in anchor regions.Long-range H3K27me3-marked chromatin interactions are associated with the coregulation of specific gene clusters.Finally,we also identified H3K27me3-associated chromatin loops associated with gene clusters in Oryza sativa and Glycine max,indicating that these long-range chromatin loops are conserved in plants.Our results provide novel insights into genome evolution and transcriptional coregulation in plants. | Linhua Sun Yuxin Cao Zhu Li Yi Liu Xiaochang Yin Xing Wang Deng Hang He Weiqiang Qian | 2023 | Journal of Integrative Plant Biology2023，65，8： | 0 |
| 13 | Geochemistry of Neoproterozoic mixosedimentite in northern Anhui and its geological significance显示文摘Major oxides,as well as trace elements (including rare earth elements) compositions have been analyzed for the mixosedimentites from Neoproterozoic Jiayuan Formation in northern Anhui,China. The results show that the concentrations of elements are closely related to the relative proportions of carbonates and terrigenous detritus (varying from 2/3 to 1/9 based on petrographic study). The ratios between some immobile elements (e.g. La,Th,Zr and Sc) are constant and then can be used as tracers for the discrimination of provenance and tectonic setting of terrigenous detritus. The results indicate that the terrigenous detritus mainly came from the felsic volcanics related to continental arc,with minor contribution from the old basement. Combined with recent research progresses,these mixosedimentites imply that the Neoproterozoic sedimentation in northern Anhui was probably taken place in a back arc basin during the convergence of Rodinia super continent between 1.0 and 0.8 Ga. | SUN Linhua GUI Herong CHEN Song | 2010 | Global Geology2010，13，3： | 0 |
| 14 | Genomic insights on the contribution of introgressions from Xian/Indica to the genetic improvement of Geng/Japonica rice cultivars显示文摘Hybridization between Xian/indica(XI)and Geng/japonica(GJ)rice combined with utilization of plant ideotypes has greatly contributed to yield improvements in modern GJ rice in China over the past 50 years.To explore the genomic basis of improved yield and disease resistance in GJ rice,we conducted a large-scale genomic landscape analysis of 816 elite GJ cultivars representing multiple eras of germplasm from China.We detected consistently increasing introgressions from three XI subpopulations into GJ cultivars since the 1980s and found that the XI genome introgressions significantly increased the grain number per panicle(GN)and decreased the panicle number per plant.This contributed to the improvement of plant type during modern breeding,changing multi-tiller plants tomoderate tiller plants with a large panicle size and increasing the blast resistance.Notably,we found that key gene haplotypes controlling plant architecture,yield components,and pest and disease resistance,including IPA1,SMG1,DEP3,Pib,Pi-d2,and Bph3,were introduced from XI rice by introgression.By GWAS analysis,we detected a GN-related gene Gnd5,which had been consistently introgressed from XI into GJ cultivars since the 1980s.Gnd5 is a GRAS transcription factor gene,and Gnd5 knockout mutants showed a significant reduction in GN.The estimated genetic effects of genes varied among different breeding locations,which explained the distinct introgression levels of XI gene haplotypes,including Gnd5,DEP3,etc.,to these GJ breeding pedigrees.These findings reveal the genomic contributions of introgressions from XI to the trait improvements of GJ rice cultivars and provide new insights for future rice genomic breeding. | Di Cui Han Zhou Xiaoding Ma Zechuan Lin Linhua Sun Bing Han Maomao Li Jianchang Sun Jin Liu Guixiu Jin Xianju Wang Guilan Cao Xing Wang Deng Hang He Longzhi Han | 2022 | Plant Communications2022，3，3： | 0 |
| 15 | Environmental baseline evaluation of lead in shallow groundwater based on statistical and spatial outlier identification显示文摘A series of methods have been applied for evaluating the environmental baseline—especially on a regional scale—because of its importance for local environmental management. However, most of the methods have been statistical in nature, and spatial variability has not been considered simultaneously. In this study, the combined use of statistical and spatial methods has been carried out to analyse lead concentrations in the shallow groundwater in the urban area of Suzhou, northern Anhui Province, China. The environmental baseline of lead in the shallow groundwater has been evaluated to be3.836–8.240 lg/l after removal of either statistical or spatial outliers. The results are similar to those obtained by model-based objective methods, and further demonstrate that the combination method is more reasonable for environmental baseline evaluation. | Linhua Sun | 2015 | Chinese Journal Of Geochemistry2015，34，3： | 0 |
| 16 | Increased long-distance and homo-trans interactions related to H3K27me3 in Arabidopsis hybrids显示文摘In plants,the genome structure of hybrids changes compared with their parents,but the effects of these changes in hybrids remain elusive.Comparing reciprocal crosses between Col×C24 and C24×Col in Arabidopsis using high-throughput chromosome conformation capture assay(Hi-C)analysis,we found that hybrid three-dimensional(3D)chromatin organization had more long-distance interactions relative to parents,and this was mainly located in promoter regions and enriched in genes with heterosis-related pathways.The interactions between euchromatin and heterochromatin were increased,and the compartment strength decreased in hybrids.In compartment domain(CD)boundaries,the distal interactions were more in hybrids than their parents.In the hybrids of CURLY LEAF(clf)mutants clfCol×clfC24and clfC24×clfCol,the heterosis phenotype was damaged,and the long-distance interactions in hybrids were fewer than in their parents with lower H3K27me3.ChIP-seq data revealed higher levels of H3K27me3 in the region adjacent to the CD boundary and the same interactional homo-trans sites in the wild-type(WT)hybrids,which may have led to more long-distance interactions.In addition,the differentially expressed genes(DEGs)located in the boundaries of CDs and loop regions changed obviously in WT,and the functional enrichment for DEGs was different between WT and clf in the longdistance interactions and loop regions.Our findings may therefore propose a new epigenetic explanation of heterosis in the Arabidopsis hybrids and provide new insights into crop breeding and yield increase. | Zhaoxu Gao Yanning Su Le Chang Guanzhong Jiao Yang Ou Mei Yang Chao Xu Pengtao Liu Zejia Wang Zewen Qi Wenwen Liu Linhua Sun Guangming He Xing Wang Deng Hang He | 2024 | Journal of Integrative Plant Biology2024，66，2： | 0 |
| 17 | Molecular exchange and passivation at interface afford high-performing perovskite solar cells with efficiency over 24%显示文摘The interface is crucial for perovskite solar cells(PSCs).However,voids at interfaces induced by the trapped hygroscopic dimethyl sulfoxide(DMSO)can reduce charge extraction and accelerate the film degradation,seriously damaging the efficiency and stability.In this work,4,4’-dinonyl-2,2’-dipyridine(DN-DP),a Lewis base with long alkyl chains is introduced to solve this problem.Theoretical calculated and experimental results confirm that the dipyridyl group on DN-DP can more strongly coordinate with Pb^(2+)than that of the S=O group on DMSO.The strong coordination effect plays a crucial role in removing the DMSO-based adduct and reducing the formation of voids.Due to the electron-donating properties of pyridine,the existence of DN-DP in the perovskite film can passivate the defects and optimize the energy level alignment of the perovskite configuration.The open-circuit voltage(VOC)of the DN-DP-based PSC is improved from 1.107 V(control device)to 1.153 V,giving rise to a power conversion efficiency(PCE)of24.02%.Furthermore,benefiting from the moisture resistance stemming from the hydrophobic nonyl group,the PCE retains 90.4%of the initial performance after 1000 h of storage in the ambient condition. | Jianjun Sun Wangchao Chen Yingke Ren Yunjuan Niu Zhiqian Yang Li'e Mo Yang Huang Zhaoqian Li Hong Zhang Linhua Hu | 2023 | Journal of Energy Chemistry2023，，7： | 0 |
| 18 | Distinct gut microbiota and health outcomes in asymptomatic infection,viral nucleic acid test re-positive,and convalescent COVID-19 cases显示文摘Gut microbiota composition is suggested to associate with coronavirus disease 2019(COVID-19)severity,but the impact of gut microbiota on health outcomes is largely unclear.We recruited 81 individuals from Wuhan,China,including 13 asymptomatic infection cases(Group A),24 COVID-19 convalescents with adverse outcomes(Group C),31 severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)re-positive cases(Group D),and 13 non-COVID-19 healthy controls(Group H).The microbial features of Groups A and D were similar and exhibited higher gut microbial diversity and more abundant short-chain fatty acid(SCFA)-producing species than Group C.Group C was enriched with opportunistic pathogens and virulence factors related to adhesion and toxin production.The abundance of SCFA-producing species was negatively correlated,while Escherichia coli was positively correlated with adverse outcomes.All three groups(A,C,and D)were enriched with the mucusdegrading species Akkermansia muciniphila,but decreased with Bacteroides-encoded carbohydrate-active enzymes.The pathways of vitamin B6 metabolic and folate biosynthesis were decreased,while selenocompound metabolism was increased in the three groups.Specifically,the secondary bile acid(BA)metabolic pathway was enriched in Group A.Antibiotic resistance genes were common among the three groups.Conclusively,the gut microbiota was related to the health outcomes of COVID-19.Dietary supplementations(SCFAs,BA,selenium,folate,vitamin B6)may be beneficial to COVID-19 patients. | Ruqin Lin Mingzhong Xiao Shanshan Cao Yu Sun Linhua Zhao Xiaoxiao Mao Peng Chen Xiaolin Tong Zheyuan Ou Hui Zhu Dong Men Xiaodong Li Yiqun Deng Xian-En Zhang Jikai Wen | 2022 | mLife2022，1，2： | 0 |
| 19 | Nitrogen starvation induces genome-wide activation of transposable elements in Arabidopsis显示文摘Nitrogen(N)availability is a major limiting factor for plant growth and agricultural productivity.Although the gene regulation network in response to N starvation has been extensively studied,it remains unknown whether N starvation has an impact on the activity of transposable elements(TEs).Here,we report that TEs can be transcriptionally activated in Arabidopsis under N starvation conditions.Through genetic screening of idm1-14 suppressors,we cloned GLU1,which encodes a glutamate synthase that catalyzes the synthesis of glutamate in the primary N assimilation pathway.We found that glutamate synthase 1(GLU1)and its functional homologs GLU2 and glutamate transport 1(GLT1)are redundantly required for TE silencing,suggesting that N metabolism can regulate TE activity.Transcriptome and methylome analyses revealed that N starvation results in genome-wide TE activation without inducing obvious alteration of DNA methylation.Genetic analysis indicated that N starvationinduced TE activation is also independent of other well-established epigenetic mechanisms,including histone methylation and heterochromatin decondensation.Our results provide new insights into the regulation of TE activity under stressful environments in planta. | Yue Wang Yi Liu Shaofeng Qu Wenjie Liang Linhua Sun Dong Ci Zhitong Ren Liu-Min Fan Weiqiang Qian | 2022 | Journal of Integrative Plant Biology2022，64，12： | 0 |
| 20 | Geochemical characteristics of REE in the Late Neo-proterozoic limestone from northern Anhui Province, China显示文摘Ten representative limestone samples [six from Wangshan Formation(WL) and the other four from Gouhou Formation(GL)] were collected from outcrops of the northern Anhui Province, and REE concentrations in limestone were measured by ICP-MS. The depositional environment and source of the REE were analyzed, and the results implys that the total REE of samples are low compared with the recent marine sediments, which range from 9.61 to 54.18 mg/kg and an average of 22.93 mg/kg. The PAAS-normalized REE+Y patterns of limestone are characterized by(1) light REE depletion in WL and enrichment in GL with the values of(Nd/Yb)SN ranging form 0.65 to 0.91 and 1.12 to 1.46, respectively;(2) light negative Ce anomaly(0.85–1.02) and positive La anomaly(0.92–1.27); and(3) both Eu(0.91–1.23) and Y(1.42–2.38) expressing light positive anomaly. The character indicated that the depositional environment was oxygenated, with infection by the hydrothermal activity and contamination of detritus. | CHEN Song GUI Herong SUN Linhua | 2014 | Chinese Journal Of Geochemistry2014，33，2： | 0 |
