The sluggish intercalation kinetics of potassium ions in various anode materials severely hinders the practical application of potassium ion batteries(PIBs) in the field of new energy storage. To overcome this difficulty, we developed a green and recyclable molten-salt(MS) strategy using natural tremella as raw material to construct self-N-doped two-dimensional(2D)tremella-derived carbon nanosheets(TCNs), which possesses large specific surface area(SSA), expanded interlayer spacing and rich defects/active sites. Thanks to the unique 2D nanosheet structure and self-N doping, TCNs800 electrode exhibits superior K+storage capacity(386.3 mA h g^(-1) at 0.1 A g^(-1)), ultrafast rate performance(119.7 mA h g^(-1) at 2.0 A g^(-1)) and long-term cycling stability(122.9 mA h g^(-1) with the Coulombic efficiency of near 100% after 1000 cycles). Moreover, detailed electrochemical kinetic analysis shows that the potassium-ion storage mechanism of TCNs800 electrode has enhanced by the pseudocapacitancecontrolled behavior. This work proves an effective green and environmentally friendly MS strategy to prepare 2D biomass nanosheet materials, and provides a reference for exploring excellent electrode materials with pseudocapacitance-controlled behavior.

On Ding homological dimensions

引用

Applied Mathematics(A Journal of Chinese Universities) 2015年第4期30卷 491-502页

作者： zhu hai-yan College of Science Zhejiang University of Technology

In this paper, we investigate Ding projective dimensions and Ding injective di- mensions of modules and rings. Let R be a ring with rDPD（R） = n 〈 ∞, and let YYl = {Mild（M）〈 ∞}. We prove that （DP,W1） is a complete hereditary cotorsion pair such that a module M belongs to DD∩W1 if and only if M is projective, moreover, 1421 = （M[pd（M）〈 ∞} = {MIfd（M） ≤ n} = {MIpd（M） ≤ n}. Then we introduce and inves- tigate Ding derived functor Dext^i（-, -）, and use it to characterize global Ding dimension. We show that if R is a Ding-Chen ring, or if R is a ring with rDPD（R）〈≤ and rDID（R）〈 ≤, then rDPD（R）〈 n if and only if rDID（R）〈 n if and only if Dext^n＋i（M,N） = 0 for all modules M and N and all integer i ≥ 1.

ABP41 is Involved in the Pollen Tube Development via Fragmenting Actin Filaments

引用

Molecular Plant 2008年第6期1卷 1048-1055页

作者： Ting Wang yun Xiang Jian Hou hai-yun Ren Key Laboratory of Cell Proliferation and Regulation Biology of Ministry of Education Beijing Normal University Beijing 100875 People's Republic of China

ABP41 is identified as a novel member of plant villin/gelsolin/fragmin superfamily proteins from lily pollen, which binds stoichiometrically to actin filaments and severs them in vitro. To further understand its in-vivo function and the potential molecular mechanisms, biochemical analysis, fluorescence microscopic observation and microinjection assays were performed. Different biochemical measurements showed that ABP41 maintained actin filaments in forms of short F-actin in vitro. Microinjection of ABP41 into pollen tubes could fragment the pre-existing actin filaments, inhibit the velocity of cytoplasmic streaming, and shorten the length of the clear zone of pollen tube. In addition, it was found that the endogenous ABP41 expressing level was dynamically corresponding to the short actin filament structure in pollen at different stages of pollen germination. Our results suggest that ABP41 is involved in the regulation of actin dynamics during the pollen germination process via maintenance of short dynamic actin filaments.

INTERMOLECULAR AND INTRAMOLECULAR INTERACTIONS OF POLYMER GUAR GUM IN SOLUTIONS

引用

Chinese Journal of Polymer Science 2005年第5期23卷 557-559页

作者： yun-fei Yan hai-yang Yang Wen-yong Liu Ping-ping zhu Ping-sheng He Department of Polymer Science and Engineering University of Science and Technology of China Hefei 230026 China Structure Research Laboratory University of Science and Technology of China Hefei 230026 China

The tetrahedral borate ion can crosslink with polymer guar gum in aqueous solutions. If the concentration of guar gum is less than 0.045 g/dL, the intramolecular interaction between guar gum and borate ion increases due to the formation of crosslinks. As a result, the polymer chains of guar gum in solution shrink in size and the reduced viscosity of polymer solution decreases accordingly. On the other hand, if the concentration of guar gum is greater than 0.045 g/dL, the intermolecular interaction becomes apparent due to the same reason. The polymer chains, therefore, associate together and the reduced viscosity of polymer solution increases considerably. According to this technique, the critical concentration c^＊, presented by de-Gennes, is determined successfully.

miR-99a-5p inhibits target gene FZD5 expression and steroid hormone secretion from goat ovarian granulosa cells

Journal of Integrative Agriculture 2022年第4期21卷 1137-1145页

作者： zhu Lu JING Jing QIN Shuai-qi LU Jia-ni zhu Cui-yun ZHENG Qi LIU Ya FANG Fu-gui LI yun-sheng ZHANG yun-hai LING Ying-hui College of Animal Science and Technology Anhui Agricultural UniversityHefei 230036P.R.China Local Animal Genetic Resources Conservation and Biobreeding Laboratory of Anhui Province Hefei 230036P.R.China

MicroRNA(miRNA) has vital regulatory effects on the proliferation, differentiation and secretion of ovarian granulosa cells, but the role of miR-99a-5p in goat ovarian granulosa cells(GCs) is unclear. Both miR-99a-5p and Frizzled-5(FZD5) were found to be expressed in GCs in goat ovaries via fluorescence in situ hybridization and immunohistochemistry, respectively, and FZD5 was verified(P<0.001) as a target gene of miR-99a-5p by double luciferase reporter gene experiments. Furthermore, FZD5 mRNA and protein expression were both found to be regulated(P<0.05) by miR-99a-5p in GCs. Moreover, the overexpression of miR-99a-5p or knockdown of FZD5 suppressed(P<0.05) estradiol and progesterone secretion from the GCs, as determined by ELISA. In summary, miR-99a-5p inhibits target gene FZD5 expression and estradiol and progesterone synthesis in GCs. Our study thus provides seminal data and new insights into the regulatory mechanisms of follicular development in the goat and other animals.
