Ion conductive membranes(ICMs)with highly conductive proton selectivity are of significant importance and greatly desired for energy storage devices.However,it is extremely challenging to construct fast proton-selective transport channels in ICMs.Herein,a membrane with highly conductive proton selectivity was fabricated by incorporating porous carbon sieving nanospheres with a hollow structure(HCSNs)in a polymer matrix.Due to the precise ion sieving ability of the microporous carbon shells and the fast proton transport through their accessible internal cavities,this advanced membrane presented a proton conductivity(0.084 S·cm^(-1))superior to those of a commercial Nation 212(N212)membrane(0.033S·cm^(-1))and a pure polymer membrane(0.049 S·cm^(-1)).The corresponding proton selectivity of the membrane(6.68×10^(5) S·min·cm^(-3))was found to be enhanced by about 5.9-fold and 4.3-fold,respectively,compared with those of the N212 membrane(1.13×10^(5) S·min·cm^(-3))and the pure membrane(1.56×10^(5) S·min·cm^(-3)).Low-field nuclear magnetic resonance(LF-NMR)clearly revealed the fast protonselective transport channels enabled by the HCSNs in the polymeric membrane.The proposed membrane exhibited an outstanding energy efficiency(EE)of 84%and long-term stability over 1400 cycles with a0.065%capacity decay per cycle at 120 mA·cm^(-2) in a typical vanadium flow battery(VFB)system.

Objectives:Peach(Prunus persica L.)is an ancient fruit tree that originated from China.It is the climacteric fruit belonging to genus Prunus in family Rosaceae.Ethylene,which is produced during ripening,accelerates fruit softening,and therefore peaches cannot be stored for a long time.Materials and Methods:To study the mechanism of fruit late ripening,transcriptome analysis of the fruit of a late-ripening mutant of'Jinghong'peach was performed to identify genes and pathways involved in fruit late ripening.Results:A total of 1805,1511,and 2309 genes were found to be differentially expressed in W2_vs_M1,W3_vs_M2,and W3_vs_M3,respectively.Functional enrichment analysis of the differentially expressed genes showed they were related to carotenoid biosynthesis,starch and sucrose metabolism plant hormone signal transduction,flavonoid biosynthesis,and photosynthesis.The expression trends of ripening-related genes that encode transcription factors and plant hormone signal transduction-related genes that encode enzymes were similar.Conclusions:It will help to elucidate the transcriptional regulatory network of fruit development in the spontaneous late-ripening mutant of‘Jinghong’peach and provide a theoretical basis for understanding the molecular regulatory mechanism of fruit ripening.

为能更精确地表征纱线条干三维特征,实现纱线条干均匀度的质量评估,采用多视角图像对纱线条干均匀度的测量进行研究。首先选择5种不同线密度的环锭纺纯棉纱,通过搭建多视角纱线图像获取装置,实现纱线多个角度的图像采集;其次对获取的4个方向的纱线图像进行自动阈值分割、图像自动裁剪、毛羽快速清除以及孤立区域去除等处理,得到清晰、无噪点的纱线主干图像;最后求得纱线主干的单视角与多视角直径、CV值,并提出新的表征纱线条干不匀的多视角不匀均值(CV_(n))指标和三维条干变异系数(S)指标。其数据结果与乌斯特条干仪的测试结果对比表明:2种测试方法检测的纱线直径相差不大,都随着线密度的减小而减小;单视角和多视角下,0.3 mm片段长度下纱线直径CV值、8 mm片段长度下纱线直径CV值与乌斯特条干仪测得的结果趋势变化一致;提出的三维条干变异系数S虽大于乌斯特条干仪测得的CV值,但总体趋势保持一致。

Porous carbon materials(PCMs)play a pivotal role in diverse applications,such as energy storage,adsorption,catalysis,environmental remediation,and microwave adsorption.The selection of carbon precursors,in particular,is crucial for tailoring porous structures with specific functionalities.Biomass,with its rich carbon feedstock,abundant availability,renewability,and versatile structures,has emerged as a promising precursor for porous carbon material synthesis.This review comprehensively summarizes the recent advances in biomass-derived porous carbon materials(BPCMs)encompassing synthetic strategy,morphology,structural composition,and multiple applications.We first review synthetic approaches aiming at regulating porosity,followed by morphological and composition features of BPCMs,with a special emphasis on elucidating the dimensional clarification and heteroatom doping effects.The discussion then extends to the wide-ranging applications of BPCMs,covering energy-related applications and CO_(2) adsorption to environmental remediation.Finally,the review outlines the existing challenges and prospects in the field.In summary,this review systematically describes BPCMs and provides valuable guidance for researchers to select and synthesize BPCMs that meet specific functional requirements.

Hyperoside promotes pollen tube growth by regulating the depolymerization effect of actin depolymerizing factor 1 on microfilaments in okra

Horticulture Research 2021年第1期8卷 2227-2240页

Mature pollen germinates rapidly on the stigma,extending its pollen tube to deliver sperm cells to the ovule for fertilization.The success of this process is an important factor that limits output.The flavonoid content increased signi ficantly during pollen germination and pollen tube growth,which suggests it may play an important role in these processes.However,the speci fi c mechanism of this involvement has been little researched.Our previous research found that hyperoside can prolong the flowering period of Abelmoschus esculentus(okra),but its speci fic mechanism is still unclear.Therefore,in this study,we focused on the effect of hyperoside in regulating the actin-depolymerizing factor(ADF),which further affects the germination and growth of pollen.We found that hyperoside can prolong the effective pollination period of okra by 2-3-fold and promote the growth of pollen tubes in the style.Then,we used Nicotiana benthamiana cells as a research system and found that hyperoside accelerates the depolymerization of intercellular micro fi laments.Hyperoside can promote pollen germination and pollen tube elongation in vitro.Moreover,AeADFl was identi fied out of all AeADF genes as being highly expressed in pollen tubes in response to hyperoside.In addition,hyperoside promoted AeADF1-mediated micro filament dissipation according to micro filament severing experiments in vitro.In the pollen tube,the gene expression of AeADFl was reduced to 1/5 by oligonucleotide transfection.The decrease in the expression level of AeADFl partially reduced the promoting effect of hyperoside on pollen germination and pollen tube growth.This research provides new research directions for flavonoids in reproductive development.

Ce0.6Mn0.4O2 catalysts with different sources of manganese and Ce0.6-xZrxMn0.4O2 mixed oxide catalysts were prepared by coprecipitation method and were characterized by N2 adsorption-desorption,TPR,XRD,and XPS techniques.The activities of the prepared catalysts for ethyl acetate combustion,and the effects of calcination temperature and space velocity on catalytic activity were investigated.The results showed that partial replacement of Mn（NO3）2 with KMnO4 as sources of manganese could improve activities of catalysts.Ce0.45Zr0.15Mn0.4O2 catalyst exhibited the best catalytic activity and high thermal stability,e.g.,T90 could be still below 210℃ even if space velocity was up to 20000h-1.
