| 1 | Design and syntheses of functionalized copper-based MOFs and its adsorption behavior for Pb(Ⅱ)显示文摘A novel copper-based MOFs adsorbent(Cu-BTC-Th) was prepared using an one-step method by introducing a new organic ligand of 4-thioureidobenzoicacid(Th) with active groups for selectively adsorbing Pb(Ⅱ) from aqueous solutions. The chemical composition and structure of the prepared MOFs materials were characterized by scanning electron microscope(SEM), X-ray diffraction(XRD), fourier transform infrared spectroscopy(FTIR), X-ray photoelectron spectroscopy(XPS), Brunner-Emmet-Teller(BET) analysis, and zeta potential measurements. The adsorption capability of the prepared Cu-MOFs was significantly enhanced by introducing the new organic ligand of Th in the materials. The maximum adsorption capacity of the Cu-BTC-Th for Pb(Ⅱ) attains 732.86 mg/g under the optimal conditions. In addition,the adsorption kinetics and adsorption isotherm analysis showed that the adsorption process followed the pseudo-second-order kinetic model and Langmuir adsorption model, indicating that the adsorption of Pb(Ⅱ) by Cu-BTC-Th was a monolayer chemisorption. The adsorption mechanism of Cu-BTC-Th for Pb(Ⅱ)was discussed and revealed. On one hand, the adsorption of Pb(Ⅱ) is mainly through ion exchange with the Cu(Ⅱ). On the other hand, the-NH2 and-C=S functional groups introduced in the Cu-BTC-Th materials have stronger coordination ability with the Pb(Ⅱ) ions to enhance the adsorption capability. | Jingping Zhong Jian Zhou Minsi Xiao Jun Liu Jili Shen Juan Liu Sili Ren | 2022 | Chinese Chemical Letters2022，33，2： | 3 |

| 3 | Continuous Detection of pH-responsive Drug Delivery System in Cells in situ by Confocal Laser Scanning Microscopy显示文摘Mesoporous 硅石 nanoparticles (MSN ) chitosan-poly 由 pH 应答的聚合物是涂的(甲基丙烯酸)(CS-PMAA ) 。这个 nano 药交货系统证明好应用程序前景和聚合物涂的 microspheres 在生物医学的地里正在答应地点特定的 anticancer 药交货搬运人。在在 situ 的房间的 pH 应答的药交货系统的连续察觉,利用 MSN/CS-PMAA 合成 microspheres,被建议。二种不同房间线,肿瘤房间线(Hela ) 和正常体的房间(293T ) ,被用来调查这药的行为在房间的装载系统。结论能被得出从荧光灯图象由扫描显微镜学( CLSM )的共焦的激光获得了,修改装载药的 microspheres ( MSN/CS-PMAA )更容易被摄取进房间,由 HeLa/293T 房间的 DOX@FITC-MSN/CS-PMAA 的举起在 pH 7.4/pH 被执行 6.8 ,纪录影片在摄取过程期间被释放,因为流出运输,荧光紧张与时间减少了并且漂白相片。由流动 cytometry 的 Fluoresence 察觉作为比较被执行。连续荧光灯在 situ 的观察能广泛地在房间在药交货系统的 pH 应答的释放进程被使用。 | Yang Sun Zhipeng Ran Hongyan Tang Yong Li Wenshuang Song Qingguang Ren Wuli Yang Jilie Kong | 2013 | Chinese Journal of Chemistry2013，31，6： | 0 |
| 4 | Morphology and mechanical performance between the skin surface of Rana dybowskii and Bufo gargarizans显示文摘Anuran skin is a typical natural biomaterial with multifunctional features.A specific comparison of mechanical performance and morphology related to them was performed in the skin of Rana dybowskii and Bufo gargarizans using the tensile testing technique and morphological equipment.Rana dybowskii's skin has soft smooth surface covered by polygonal epidermal cells,while the Bufo gargarizans species has tough and uneven skin surface due to numerous verrucae structures.The collagen fibre bundles in lower dermis of Bufo gargarizans have wavelike organisation while the bundles of Rana dybowskii show a parallel arrangement.The mean elastic modulus of Rana dybowskii was nine times higher than that of Bufo gargarizans.This study clarified that the arrangement of collagen fibres play an important role in the strength and elasticity of skin material. | Mo Li Chunyu Du Jili Wang Zibo Gao Xiao Yang Donghui Chen Jin Tong Lili Ren | 2021 | Biosurface and Biotribology2021，7，3： | 0 |
