| 1 | Comparing the intestinal bacterial communies of sympatric wintering Hooded Crane (Grus monacha) and Domestic Goose(Anser anser domesticus)显示文摘Background:Gut microbiota play crucial roles in host health.Wild birds and domestic poultry often occupy sympatric habitats,which facilitate the mutual transmission of intestinal microbes.However,the distinct intestinal microbial communities between sympatric wild birds and poultry remain unknown.At present,the risk of interspecies transmission of pathogenic bacteria between wild and domestic host birds is also a research hotspot.Methods:This study compared the intestinal bacterial communities of the overwintering Hooded Crane(Grus monacha)and the Domestic Goose(Anser anser domesticus)at Shengjin Lake,China,using Illumina high-throughput sequencing technology(Mi-Seq platform).Results:Our results revealed that Firmicutes,Actinobacteria,Proteobacteria,Bacteroidetes and Chloroflexi were the dominant bacterial phyla in both hosts.The gut bacterial community composition differed significantly between sympatric Hooded Cranes and Domestic Geese.However,the hosts exhibited little variation in gut bacterial alphadiversity.The relative abundance of Firmicutes was significantly higher in the guts of the Hooded Cranes,while the relative abundances of Actinobacteria,Proteobacteria,Bacteroidete and Chloroflexi were significantly higher in guts of Domestic Geese.Moreover,a total of 132 potential pathogenic operational taxonomic units(OTUs)were detected in guts of Hooded Cranes and Domestic Geese,and 13 pathogenic OTUs(9.8%)were found in both host guts.Pathogenic bacterial community composition and diversity differed significantly between hosts.Conclusions:The results showed that the gut bacterial community composition differs significantly between sympatric Hooded Cranes and Domestic Geese.In addition,potential pathogens were detected in the guts of both Hooded Cranes and Domestic Geese,with 13 pathogenic OTUs overlapping between the two hosts,suggesting that more attention should be paid to wild birds and poultry that might increase the risk of disease transmission in conspecifics and other mixed species. | Rong Fu Xingjia Xiang Yuanqiu Dong Lei Cheng Lizhi Zhou | 2020 | Avian Research2020，11，2： | 5 |

| 3 | Giant negative photoresistance of epitaxial manganite La_(2/3)Ca_(1/3)MnO_(3-δ) film显示文摘The La2/3Ca1/3Mn O3-δ film has been deposited on the(001) Sr Ti O3 substrate and its temperature-dependent photoconductive properties have been investigated from 80 to 300 K. The La2/3Ca1/3Mn O3-δfilm has a novel photoelectric property due to its oxygen-deficient structure. We observed laser-induced giant negative photoresistance of the sample in a wide temperature range. The change rate of negative photoresistance was nearly 100% at the low temperature when the sample was irradiated by 532 nm laser. In addition, this effect was sensitive to the power of laser irradiation. The oxygen-deficiency of La2/3Ca1/3Mn O3-δfilm seems to have an impact on the laser-induced resistance variation. The experimental results made the La2/3Ca1/3Mn O3-δfilm a promising application as a photoswitch device. | XI JianFeng ZHAO Kun NI Hao XIANG WenFeng FENG Xin SUN Qi LU ZhiQing XIAO LiZhi | 2015 | Science China Chemistry2015，58，12： | 0 |
| 4 | Novel Germoles and Their Ladder-Type Derivatives:Modular Synthesis,Luminescence Tuning,and Electroluminescence显示文摘Considerable effort has been devoted to the design of silicon-containingπ-conjugated materials for application in optoelectronic devices and fluorescent bioimaging.However,the synthesis and spectroscopic tuning of germanium(Ge)-conjugated systems are challenging because of the paucity of synthetically useful methods.Herein,we report a simple and effective method of lithium naphthalenide-induced intramolecular cyclization to construct architecturally diverse Ge-containingπ-conjugated molecules,including benzogermoles and their ladder-type derivatives,with high yields of up to 92%.The photophysical properties of these molecules can befinely controlled by the introduction of electrondonating or-withdrawing substituents,and intense luminescence ranging from deep-blue to red regions in the solid state was observed.A quantitative model based on the Hammett constant against the luminescence wavelength showed a good linear correlation,allowing us to reliably predict and design luminescent materials with specific properties for applications.Notably,Ge-bridged ladder-type derivatives exhibited high photoluminescence and efficient deep-blue electroluminescence with good color purity.We believe this study will open a new avenue to organogermanium chemistry and offers greater flexibility for electronic structural tuning. | Xiaoshuang Xiang Zhikuan Zhou Xing Wu Zhigang Ni Lizhi Gai Xuqiong Xiao Liwen Xu Zujin Zhao Hua Lu Zijian Guo | 2022 | CCS Chemistry2022，4，12： | 0 |
| 5 | Mid-to-high-end Makeup Market:the Arena of the Next Decade for Domestic Brands显示文摘From Perfect Diary and Florasis to Winona,emerging domestic makeup brands have gradually risen in recent years under the“halo of domestic products.”However,the adjectives used to modify domestic beauty brands seem to always stay at the levels of“affordable,”“cost-effective,”“conscionable,”and“cheap,”as if domestic products are born as substitutes for the big brands from Europe and America. | Xiang Honglin Zhou Lizhi | 2022 | China Detergent & Cosmetics2022，7，3： | 0 |
| 6 | Fabrication and Excellent Antibacterial Activity of Well-defined CuO/Graphdiyne Nanostructure显示文摘Copper oxide(CuO),due to its low cost,good chemical and physical stability,has recently been given special attention as a potential candidate for antibacterial agents.However,developing novel CuO nanocomposites with improved antibacterial property and unraveling the interface promotion mechanism has been a fundamental challenge for decades.Herein,well-defined CuO/graphdiyne(CuO/GDY)nanostructures with uniformly anchored CuO nanoparticles(ca.4.5 nm)have been fabricated.The CuO/GDY nanostructure exhibited superior E.coli inactivation efficiency,which is nearly 19 times and 7.9 times higher than the bare GDY and commercial CuO,respectively.The improved E.coli inactivation performance was mainly due to the increased reactive·O_(2)−species generated by the activation of molecular O2 over CuO/GDY surface.These findings demonstrate the efficient antibacterial activity of well-defined CuO/GDY nanostructures and provide insights on the development of efficient GDY-based antibacterial materials. | PAN Chuanqi LIU Xiaoxuan ZHANG Xiang MAO Feihong XU Peiyan ZHU Yuhua DENG Hongtao LUO Zhu SUN Hongwei ZHANG Lizhi GUO Yanbing | 2021 | Chemical Research in Chinese Universities2021，37，6： | 0 |
| 7 | Layer stacked SiO_(x) microparticle with disconnected interstices enables stable interphase and particle integrity for lithium-ion batteries显示文摘Severe mechanical fractu re and unstable interphase,associated with the large volumetric expansion/contraction,significantly hinder the application of high-capacity SiO_(x)materials in lithium-ion batteries.Herein,we report the design and facile synthesis of a layer stacked SiO_(x)microparticle(LS-SiO_(x))material,which presents a stacking structure of SiO_(x)layers with abundant disconnected interstices.This LS-SiO_(x)microparticle can effectively accommodate the volume expansion,while ensuring negligible particle expansion.More importantly,the interstices within SiO_(x)microparticle are disconnected from each other,which efficiently prevent the electrolyte from infiltration into the interior,achieving stable electrode/-electrolyte interface.Accordingly,the LS-SiO_(x)material without any coating delivers ultrahigh average Coulombic efficiency,outstanding cycling stability,and full-cell applicability.Only 6 cycles can attain>99.92%Coulombic efficiency and the capacity retention at 0.05 A g^(-1)for 100 cycles exceeds99%.After 800 cycles at 1 A g^(-1),the thickness swelling of LS-SiO_(x)electrode is as low as 0.87%.Moreover,the full cell with pure LS-SiO_(x)anode exhibits capacity retention of 91.2%after 300 cycles at 0.2 C.This work provides a novel concept and effective approach to rationally design silicon-based and other electrode materials with huge volume variation for electrochemical energy storage applications. | Yang Ren Xucai Yin Lizhi Xiang Rang Xiao Hua Huo Geping Yin Chunyu Du | 2023 | Journal of Energy Chemistry2023，，11： | 0 |
| 8 | Fine Tuning of the Electronic Properties of Novel BTPE Using Oligosilanyl Linkages and Their Application in Rapid High-Resolution Visualization of Latent Fingerprints显示文摘Structural modifications throughπ-interactions usually result in redshifts in luminescence and,as a consequence,the loss of the natural color of the chromophore.Besides,employing Si-Siσ-bridging to manipulate the electronic properties of organic materials has remained largely unexplored.Herein,we report a series of novel bis-tetraphenylethenes(BTPEs)with oligosilanyl linkages,termed BTPE-Sin molecules,used to manipulate the photophysical properties of luminogens subtly throughσ–πconjugation.These oligosilanyl-bridged molecules were thermally,highly stable,and exhibited enhanced aggregation-induced emissions,as well as luminescence efficiencies while retaining most of their original color.Our current BTPEs fabrications have easy-to-operate,fast,and high-resolution identification properties toward LFPs.Also,they are highly specific to individuals,and hence,vital in forensic investigations.We achieved these features through the introduction of oligosilanyl chains that increased the lipophilicity of the significantly.This work offers a universal and straightforward approach for the generation of highly emissive organic materials and enables fine-tuning of their electronic properties for multifunctional applications. | Xiaoshuang Xiang Zhikuan Zhou Hongjie Feng Siyang Feng Lizhi Gai Hua Lu Zijian Guo | 2020 | CCS Chemistry2020，2，3： | 0 |
| 9 | Unraveling the reaction mechanism of low dose Mn dopant in Ni(OH)_(2) supercapacitor electrode显示文摘Mn doping is deemed as a promising strategy to improve the electrochemical performance of the a-Ni(OH)_(2)battery-type supercapacitor electrode.However,the internal structure evolution,the pathways and the dynamics of the proton/intercalated anion migration,as well as the functioning mechanism of Mn dopant to stabilize the layered structure during cycles remain unclear.Here,we unveil that irreversible oxidization of Mn^(3+)at the initial CV cycles,which will remain as Mn^(4+)in the NiO_(2)slabs after the first oxidization to effectively suppress the phase transformation fromα-Ni(OH)_(2)/γ-NiOOH toβ-Ni(OH)_(2)/β-NiOOH and further maintain the structural integrity of electrode.With a synergistic combination of theoretical calculations and various structural probes including XRD and^(2)H MAS solid state NMR,we decode the structure evolution and dynamics in the initial CV(cyclic voltammetry)cycles,including the absorption/desorption of hydrogen containing species,migration of intercalated anions/water molecules and the change of interlayer space.This present work elucidates a close relationship between doping chemistry and structural reliability,paving a novel way of reengineering supercapacitor electrode materials. | Zhiguo Zhang Hua Huo Zhenjiang Yu Lizhi Xiang Bingxing Xie Chunyu Du Jiajun Wang Geping Yin | 2021 | Journal of Energy Chemistry2021，30，10： | 0 |
| 10 | Investigation of Electrical Parameters of Fresh Water and Produced Mixed Injection in High-Salinity Reservoirs显示文摘Assuming a reservoir with a typical salt-lake background in the Qaidam Basin as a testbed,in this study the var-iation law of the rock electrical parameters has been determined through water displacement experiments with different salinities.As made evident by the results,the saturation index increases with the degree of water injec-tion.When the salinity of the injected water is lower than 80000 ppm,the resistivity of the rock samplefirst decreases,then it remains almost constant in an intermediate stage,andfinally it grows,thereby giving rise to a‘U’profile behavior.As the salinity decreases,the water saturation corresponding to the inflection point of the resistivity becomes lower,thereby leading to a wider‘U’type range and a higher terminal resistivity.For dif-ferent samples,higher initial resistivity of the sample in the oil-bearing state,and higher resistivity after low-sali-nity water washing are obtained when a thicker lithology is considered. | Jun Li Guofeng Cheng Hongwei Xiao Xiang Li Lizhi Wang Hui Xu Yu Wang Nannan Liu Shangping Chen Xing Shi | 2023 | Fluid Dynamics & Materials Processing2023，19，10： | 0 |
| 11 | The Clinical Application Value of Selective Unifocalization in the Treatment of Severe Pulmonary Artery Atresia with Ventricular Septal Defect显示文摘Background:This study aims to explore the efficacy of selective unifocalization(UF)for major aortopulmonary collateral arteries(MAPCAs)unifocalization in children with pulmonary atresia with ventricular septal defect(PA/VSD).Methods:A retrospective analysis of 13 patients with PA/VSD/MAPCAs who underwent surgery from June 2017 to December 2019.Sex,age,preoperative cardiovascular angiography test results and McGoon ratio were collected.The properties of the collateral arteries were evaluated by angiography,and selective UF for the“dendritic”MAPCAs and ligation of MAPCAs demonstrating distortion and resistance.Results:A total of 13 severe patients underwent one-stage repair,of which 1 case underwent ventricular septal fenestration and died after 2 weeks of ECMO support.The median age was 37 months,and a median weight was 14.0 kg.A right ventricular to aortic systolic pressure ratio(pRV/pAo)of no more than 0.5 was achieved in 12 living patients.Conclusion:Selective unifocalization based on MAPCAs morphology can achieved a good outcome at the early stage.This surgical concept might be provided a novel insight into treatment for some of the subgroups presenting with this complex form of PA/VSD/MAPCAs. | Jinyang Liu Bo Peng Xianchao Jiang Simeng Zhang Jiachen Li Lizhi Lv Qiang Wang Xiang Li | 2021 | Congenital Heart Disease2021，16，1： | 0 |
| 12 | Micellization of copolymers via noncovalent interaction with TPPS and aggregation of TPPS显示文摘Aggregation of 5,10,15,20-tetrakis-(4-sulfonatophenyl)-porphyrin (TPPS) was investigated in complex micelles composed of poly(ethylene glycol)-block-poly(4-vinylpyridine) (PEG-b-P4VP) and poly(2-(dimethylamino)ethyl methylacrylate)-b-poly(Nisopropylacrylamide) (PDMAEMA-b-PNIPAM) in aqueous solutions.The resultant complex micelles had a complex P4VP/ PDMAEMA/TPPS core and a mixed PEG/PNIPAM shell.Different noncovalent interaction modes between the porphyrin and each copolymer accomplished a co-effect on the aggregation of TPPS.The formation of aggregates was pH-dependent.At pH 3.2–6.5,TPPS existed as a mixture of H-aggregates and monomers because of the aromatic-aromatic interaction with P4VP and electrostatic interaction with PDMAEMA.The monomers translated into J-aggregates,stabilized by electrostatic interaction with the both polyelectrolyte blocks,upon decreasing the pH to 1.6.The free-base monomer was the one and only form for the dye at pH 11.0 due to aromatic stacking with the pyridyl rings. | ZHAO LiZhi XIANG Rui ZHANG LiYan WU ChengLin MA RuJiang AN YingLi SHI LinQi | 2011 | Science China Chemistry2011，54，2： | 0 |
