Flexible metal–insulator–metal (MIM) devices for plastic film AM-LCD

We developed new flexible metal–insulator–metal (MIM) devices subject to plastic film substrate. The structure of the MIM device is that a Ta₂O₅ insulator is covered with two flexible Al electrodes on both sides. The flexible structure of the MIM device was successfully fabricated applying our own etch-free process.     

使用T-20治疗HIV-1患者的不同策略的数学建模与研究

通过建立数学模型,描述了HIV-1感染者使用抗病毒治疗药物——融合酶抑制剂(T-20)的治疗效果．使用脉冲微分方程描述了T-20的使用过程,并考虑了两种不同的药物消除动力学:一级消除动力学与米-曼(Michaelis-Menten)消除动力学．此模型是个非自治微分方程系统,主要关注其无病平衡态,并研究当接受治疗者在服药完全依从的治疗过程中无病平衡态的稳定性．分别针对药物剂量与服药间隔得到了使得无病平衡态稳定的阈值条件．此外,还研究了间歇治疗的效果．研究表明,间歇治疗的效果甚至可以比完全不治疗还要糟糕．     

Mössbauer spectra of tin(IV) in anion exchange resins sorbed from hydrochloric and hydrobromic acid solutions

Mössbauer spectra were observed for ¹¹⁹Sn(IV) in AG 1 anion exchange resin sorbed from hydrochloric and hydrobromic acid solutions of various concentrations. The isomer shift values observed in resins sorbed from 1 and 2 or 3 N HBr were, respectively, 0·54 and 0·67 mm/sec, which were different from the value of 0·87 mm/sec for SnBr₆²⁻. Applying the isomer shift-electronegativity correlation for the octahedral complexes, these results were attributed to the hydroxo complexes, SnBr₄(OH)₂²⁻ and SnBr₅(OH)²⁻, respectively. The isomer shift value of ∼ 0·43 mm/sec observed for Sn(IV) in resin sorbed from 1–9 N HCl was concluded to be SnCl₅(OH)²⁻. From 12 N HCl, tin (IV) was sorbed as SnCl₆²⁻. When the resins were dried, they converted to SnBr₆²⁻ or SnCl₆²⁻. The spectra observed at 0·01 and 0·1 N HCl or HBr were complicated suggesting that tin(IV) was sorbed as higher hydroxo complexes.

氧化锡量子点的合成及对抗坏血酸的灵敏传感研究

采用水热法合成了一种SnO₂量子点,对其合成条件（如pH、温度、时间等）进行了优化,并使用红外光谱、X粉末衍射、粒度分析仪、荧光光谱仪等手段对量子点的物化和光学性能进行了表征。实验结果显示,合成的SnO₂量子点分散均匀、粒径为5nm左右;在310nm波长光激发下,其最强发射峰位于415nm,且表现出良好的光学稳定性。在Fe³⁺存在时,SnO₂量子点的荧光被猝灭,而Fe²⁺对SnO₂量子点的荧光没有影响,利用抗坏血酸（AA）的还原性,将Fe³⁺还原成Fe²⁺,猝灭的SnO₂量子点荧光恢复,当AA浓度为500μmol·L^-1时,SnO₂荧光恢复率达到95.88%,其他氨基酸基本没有响应。基于此,构建了一种\"off-on\"荧光探针用于抗坏血酸灵敏检测。
