| 1 | Mechanism of floral scent production in Osmanthus fragrans and the production and regulation of its key floral constituents,β-ionone and linalool显示文摘Sweet osmanthus(Osmanthus fragrans Lour.)is among the top ten most well-known flowers in China and is recognized as both an aromatic plant and ornamental flower.Here,manual sectioning,scanning electron microscopy,and transmission electron microscopy of sweet osmanthus petals revealed that large amounts of lipids are present inside the petal cells and on the cell surfaces.However,no secretory structures were observed.Instead,the petal cells protrude slightly outward,and the surfaces of the cells are adorned with highly regular brush-shaped hairs.The surfaces of the‘Yingui’petals possessed mostly curled and more numerous hairs,whereas the‘Dangui’petals possessed fewer brush-shaped and more sparsely arranged hairs.In addition,many granular substances were attached to the brush-shaped hairs,and the granules were denser on the hairs of the‘Yingui’petals compared to the hairs on the‘Dangui’petals.Furthermore,35 aromatic components in the‘Yingui’petals and 30 aromatic components in the‘Dangui’petals were detected via GC-MS.The main aromatic component of the‘Yingui’petals wasβ-ionone,whereas that of the‘Dangui’petals was linalool and its oxides.Transcriptome sequencing and qRT-PCR indicated that the highβ-ionone content in the‘Yingui’petals was due to the overexpression of CCD1 and CCD4 and that the high linalool content in the‘Dangui’petals was due to the overexpression of MECS,HDR,IDI1,and LIS1,which function upstream of the linalool synthetic pathway.In particular,the expression levels of CCD4 and LIS1 were upregulated by 5.5-and 5.1-fold in the‘Yingui’and‘Dangui’petals,respectively.One transcription factor(ERF61)was cloned and named,and the expression pattern of ERF61 in sweet osmanthus petals was found to be generally consistent with that of CCD4.Tobacco transformation experiments,yeast one-hybrid experiments,and electrophoretic mobility shift assays indicated that ERF61 binds to the CCD4 promoter and stimulates CCD4 expression,thereby regulating the synthesis ofβ-ionone in sweet osmanthus petals. | Yuanji Han Hongyun Wang Xiaodan Wang Ke Li Meifang Dong Yong Li Qian Zhu Fude Shang | 2019 | Horticulture Research2019,6,1: | 13 |
| 2 | Polymer electrolytes for Li-S batteries:Polymeric fundamentals and performance optimization显示文摘Lithium-sulfur(Li-S) batteries have been considered as one of the most promising candidates to traditional lithium ion batteries due to its low cost,high theoretical specific capacity(1675 mAh g^(-1)) and energy density(2600 Wh kg^(-1)) of sulfur.Compared with traditional liquid electrolytes,polymer electrolytes(PEs) are ever-increasingly preferred due to their higher safety,superior compatibility,long cycling stability and so on.Despite some progresses on PEs,however,there remain lots of hurdles to be addressed prior to commercial applications.This review begins with native advantages for PEs to replace LEs,and then proposes the ideal requirements for PEs.Furthermore,a brief development history of typical PEs for Li-S batteries is presented to systematically summarize the recent achievements in Li-S batteries with PEs.Noted that the structure-performance relationships of polymer matrixes for PEs are highlighted.Finally,the challenges and opportunities on the future development of PEs are presented.We hold the view that composite polymer electrolytes in virtue of the high ionic conductivity and the compatible interfacial property will be promising solution for high performance Li-S batteries. | Meifang Jiang Zengqi Zhang Ben Tang Tiantian Dong Hantao Xu Huanri Zhang Xiaolan Lu Guanglei Cui | 2021 | Journal of Energy Chemistry2021,30,7: | 3 |
| 3 | An Endotenon Sheath-Inspired Double-Network Binder Enables Superior Cycling Performance of Silicon Electrodes显示文摘Silicon(Si)has been regarded as an alternative anode material to traditional graphite owing to its higher theoretical capacity(4200 vs.372 m Ah g;).However,Si anodes suffer from the inherent volume expansion and unstable solid electrolyte interphase,thus experiencing fast capacity decay,which hinders their commercial application.To address this,herein,an endotenon sheathinspired water-soluble double-network binder(DNB)is presented for resolving the bottleneck of Si anodes.The as-developed binder shows excellent adhesion,high mechanical properties,and a considerable self-healing capability mainly benefited by its supramolecular hybrid network.Apart from these advantages,this binder also induces a Li;N/Li F-rich solid electrolyte interface layer,contributing to a superior cycle stability of Si electrodes.As expected,the DNB can achieve mechanically more stable Si electrodes than traditional polyacrylic acid and pectin binders.As a result,DNB delivers superior electrochemical performance ofSi/Li half cells and Li Ni;Co;Mn;O;/Si full cells,even with a high loading of Si electrode,to traditional polyacrylic acid and pectin binders.The bioinspired binder design provides a promising route to achieve long-life Si anode-assembled lithium batteries. | Meifang Jiang Pengzhou Mu Huanrui Zhang Tiantian Dong Ben Tang Huayu Qiu Zhou Chen Guanglei Cui | 2022 | Nano-Micro Letters2022,14,6: | 2 |

| 10 | Recyclable Joule heated low shrinkage carbon nanofiber aerogels for microscale oil/water separation显示文摘Aerogels have shown great potential as oil adsorbents but their application to the removal of microscale oil from water and their recycling remains problematic.The present work proposed a freeze-shaping method for fabricating carbon nanofiber aerogels(CNFAs)based on the direct use of one-dimensional(1D)carbon nanofibers(CNF)rather than carbonization of polymer aerogels.This technique greatly reduces volume shrinkage and increases the three-dimensional(3D)structural stability of the material.Carbon nanotubes(CNT)and gelatinized starch were incorporated in these aerogels as a conductive enhancement agent and binder,respectively,forming a“vine(CNT)-wrapped tree(CNF)”structure that improved mechanical and Joule-heating performance.The effects of glutaraldehyde added to aerogels as a crosslinking agent on mechanical properties and microstructure were also systematically investigated.The optimized CNFAs combined with low density,high porosity,good elasticity,and superior Joule-heating efficiency along with suitable adsorption capacity,excellent selectivity,and cycling stability.This material was able to selectively remove 87%and 92%of microscale acetone and dimethylformamide(DMF),respectively,from the water after nine cycles of adsorption and Joule-heating.The present work demonstrates a novel means of designing and fabricating a low shrinkage CNFA with outstanding Joule-heating performance having potential practical applications in the remediation of organic pollution. | Guangkai Hu Dong Liu Sidi Yin Bin Yu Tao Huang Hao Yu Meifang Zhu | 2022 | Journal of Materials Science & Technology2022,,32: | 0 |

| 12 | Biocompatible and antibacterial soy protein isolate/quaternized chitosan composite sponges for acute upper gastrointestinal hemostasis显示文摘Innovative biomedical applications have high requirements for biomedical materials.Herein,a series of biocompatible,antibacterial and hemostatic sponges were successfully fabricated for the treatment of acute upper gastrointestinal bleeding(AUGB).Quaternized chitosan(QC)and soy protein isolate(SPI)were chemically cross-linked to obtain porous SPI/QC sponges(named SQS-n,with n¼30,40,50 or 60 corresponding to the weight percentage of the QC content).The chemical composition,physical properties and biological activity of SQS-n were investigated.SQS-n could support the adhesion and proliferation of L929 cells while triggering no obvious blood toxicity.Meanwhile,SQS-n exhibited good broad-spectrum antibacterial activity against both grampositive bacteria(Staphylococcus aureus)and gram-negative bacteria(Escherichia coli).The in vivo hemostatic effect of SQS-n was evaluated using three different bleeding models.The results revealed that SQS-50 performed best in reducing blood loss and hemostatic time.The overall hemostatic effect of SQS-50 was comparable to that of a commercial gelatin sponge.The enhanced antibacterial and hemostatic activities of SQS-n were mainly attributed to the QC component.In conclusion,this work developed a QC-functionalized hemostatic sponge that is highly desirable for innovative biomedical applications,such as AUGB. | Zijian Wang MeiFang Ke Liu He Qi Dong Xiao Liang Jun Rao Junjie Ai Chuan Tian Xinwei Han Yanan Zhao | 2021 | Regenerative Biomaterials2021,8,4: | 0 |
