Single crystal metal-organic framework constructed by vertically self-pillared nanosheets and its derivative for oriented lithium plating

This vertically self‐pillared(VSP)structure extends the application range of traditional porous materials with facile mass/ion transport and enhanced reaction kinetics.Here,we prepare a single crystal metal‐organic framework(MOF),employing the ZIF‐67 structure as a proof of concept,which is constructed by vertically self‐pillared nanosheets(VSP‐MOF).We further converted VSP‐MOF into VSP‐cobalt sulfide(VSP‐CoS2)through a sulfidation process.Catalysis plays an important role in almost all battery technologies;for metallic batteries,lithium anodes exhibit a high theoretical specific capacity,low density,and low redox potential.However,during the half‐cell reaction(Li++e=Li),uncontrolled dendritic Li penetrates the separator and solid electrolyte interphase layer.When employed as a composite scaffold for lithium metal deposition,there are many advantage to using this framework:1)the VSP‐CoS2 substrate provides a high specific surface area to dissipate the ion flux and mass transfer and acts as a pre‐catalyst,2)the catalytic Co center favors the charge transfer process and preferentially binds the Li+with the enhanced electrical fields,and 3)the VSP structure guides the metallic propagation along the nanosheet 2D orientation without the protrusive dendrites.All these features enable the VSP structure in metallic batteries with encouraging performances.

Transparent and anti-fogging AlPO_(4)-5 films constructed by oblique oriented nano-flake crystals

In the present work,transparent and anti-fogging AlPO_(4)-5 films were prepared on glass substrates using a novel developed process.The process entails a simple in-situ sol–gel followed by vapor phase transport.The in-situ sol–gel process was implemented by coating the precursor sols for the synthesis of AlPO4-5 on the glass substrates successively using the spin-coating method.The films and powders scribed from the films were characterized by X-Ray diffraction(XRD),Fourier transform infrared spectroscopy(FT-IR),scanning electron microscope(SEM),atomic force microscope(AFM),X-ray photoelectron spectroscopy and transmission electron microscope(TEM).The unique films were composed of oblique oriented nanoflake AlPO_(4)-5 crystals with the thickness of about 20 nm.The formation of nano-flake crystals can be ascribed to the high concentration of the precursors,resulting in the formation of a supersaturation system.The obtained films showed high antifogging performance due to the superhydrophilicity with a water contact angle of lower than 1.0°.The silicone oil contact angle was also low about 8.2°.In addition,heteroatom-substituted AlPO_(4)-5 films showing different colors can be obtained easily by simply adding transition metal ions in the phosphate acid solution during the preparation that can extend the application of the method for different coating demand.

Immobilization of antibodies on the self-assembled monolayer by antigen-binding site protection and immobilization kinetic control

The orientation of the biological molecule immobi-lized on a solid surface has been critical in devel-opment of various applications. In this study, ori-entation of antibody was retained by protecting the antigen-binding site of the antibody prior to immo-bilization to -functionalized mixed self-assembled monolayer (SAM) of 12-mercaptododecanoic acid and 1-heptanethiol. More importantly, the number of immobilization bonds formed between each an-tigen-binding site protected antibody molecule and the solid surface was controlled by optimizing the mole fraction of the activated carboxyl group of the linker molecules in the mixed SAM. The amount of antibody used in this study was approximately equivalent to the amount for one monolayer surface coverage. The resulting activity of protected immo-bilized antibody was about 10 fold higher than that of random immobilized

SYNTHESIS OF A NOVEL SELF-ASSEMBLING NLO POLYMERIC FILM

By covalently binding chromophore NPP, N-(4-nitrophenyl)-(L)-prolinol, to a structurally controlled cage-like cross-linking polymer (SCCP), a modified nonlinear optical (NLO) polymeric film prepared by 'in situ poling and sol-gel' process successfully overcame the fundamental problem of NPP chromophores subliming out from the cages of the 'doped'' NLO polymeric film when heated or placed under UV light. Its d(33) (coefficient of second harmonic generation) is 2.0 X 10(-8) esu. measured by IR dichroism. The modified film has a low decay of the SHG signal and preserves 94% of the initial value after 50 days at room temperature These properties match that of the 'doped' film, indicating that the modified film also retains the main advantages of the 'doped' film.

社会价值取向对自我社会奖赏加工的影响--来自ERPs的证据

社会价值取向(Social Value Orientation,SVO)是相互依存情境下人们对自己和他人分配结果的一种稳定的社会偏好,按SVO不同可以将个体分为"亲社会取向"和"亲自我取向"个体。已有研究表明SVO影响个体对涉及自我金钱奖赏的结果评价加工,而它如何影响自我社会奖赏加工过程尚不明确。本研究让亲社会取向和亲自我取向被试完成涉及自我社会奖赏(包含社会接纳和自我成就感)的猜牌建议给予任务,同时记录其加工他人对建议的反馈(接受vs.拒绝)和他人最终结果(收益vs.损失)时诱发的脑电成分。结果发现,在建议反馈加工阶段,相比亲自我取向个体,亲社会取向个体在反馈相关负波(FRN)波幅(峰-峰值)和P3平均波幅上,建议被对方接受和被对方拒绝所诱发的波幅差异均显著;在他人最终结果加工阶段,建议被对方拒绝后,对于亲社会取向个体,对方损失诱发的反馈相关负FRN波幅比对方收益诱发的波幅更负,而对方损失诱发的P3波幅小于对方收益诱发的波幅;对于亲自我取向个体,对方损失与收益诱发的FRN波幅无差异,对方损失诱发的P3波幅显著大于对方收益诱发的波幅。这些结果表明社会价值取向调节个体对自我社会奖赏的加工。

基于U-I模型的感应电机定子磁链估计的仿真研究

定子磁场定向的直接转矩控制逐渐被广泛应用于高性能异步电机调速系统。定子磁链估计精度是影响控制系统动态、稳态性能的主要因素。由于定子电阻参数变化及低通滤波器的影响,尤其低速运行时,传统定子磁链估计方法的估计精度及快速性往往很差。提出了一个全新的改进U-I模型定子磁链估计方案,不仅解决了定子电阻整定补偿问题,而且解决了低通滤波器截止频率优化补偿问题。在此基础上,建立直接转矩控制方案的仿真系统,仿真结果表明提出的方案能够使异步电机在低速到高速范围内都能得到令人满意的性能。
