| 1 | Investigation of radionuclide ^(60)Co(Ⅱ) binding to TiO_2 by batch technique,surface complexation model and DFT calculations显示文摘The interaction between radionuclides and solid/water interfaces is important to understand the physicochemical processes of radionuclides in the natural environment.Herein,the interaction of 60Co(Ⅱ) with TiO 2 in aqueous solution as a function of pH and ionic strength was studied by using batch technique combined with surface complexation model and density functional theory(DFT) calculations.The batch experimental results showed that the adsorption of 60Co(Ⅱ) was dependent on pH and independent of ionic strength,indicating the formation of inner-sphere surface complexes on TiO 2 surfaces.The results of surface complexation models and DFT calculations indicated that the surface species of 60Co(Ⅱ) adsorbed on TiO 2 followed the trend:B structure(i.e.,60Co(Ⅱ) was linked to one bridge oxygen site) was the dominant surface species at low pH,and TT structure(i.e.,60Co(Ⅱ) was linked to two terminal oxygen sites) became the important surface complex at neutral and alkaline pH values.These results demonstrated that a multi-technique approach could lead to definitive information on the structures of adsorbed 60Co(Ⅱ) at the molecular level at the TiO 2 /water interfaces,as well as realistic models to rationalize and accurately evaluate the macroscopic manifestations of radionuclide adsorption phenomena. | REN XueMei YANG ShiTong TAN XiaoLi CHEN ChangLun WANG XiangKe | 2012 | Science China Chemistry2012，55，9： | 4 |

| 7 | Influences of POSS-E-GO Content on Mechanical Properties of Bio-based Epoxy/DOPO-POSS Nanocomposites显示文摘The bio-based epoxy nanocomposite(GAER/DOPO-POSS)was prepared from gallic epoxy resin(GAER)and polyhedral oligomeric silsesquioxane(which containing 9,10-dihydrogen-9-oxo-10-phosphorus-phenanthrene-10-oxide groups,called DOPO-POSS).The polyhedral oligomeric silsesquioxane containing epoxy groups(E-POSS)was grafted onto aminated graphene oxide(E-GO),then the novel POSS-E-GO was obtained.The POSS-E-GO was used as modifier for GAER/DOPO-POSS nanocomposite.The influences of POSS-E-GO content on mechanical properties,dynamic mechanical properties and thermal stability of GAER/DOPO-POSS nanocomposites were determined.The experimental results show that POSS-E-GO can significantly improve the toughness of the GAER/DOPO-POSS nanocomposite.When 0.5wt% POSS-E-GO was added in GAER/DOPO-POSS nanocomposite,the impact strength of the nanocomposite was 4.74 kJ/m^(2) higher than that in the absence of POSS-E-GO,meantime the initial thermal degradation temperature was 277℃. | 杜永刚 SHI Gonghui WANG Jiaming WANG Yiming WANG Xuhua WANG Liwei YANG Jinhui REN Shitong | 2022 | Journal of Wuhan University of Technology(Materials Science)2022，37，4： | 1 |
| 8 | 接触时间、pH值、土壤中腐植酸/富里酸、离子强度和温度对MX-80膨润土吸附U(VI)的影响显示文摘本文在室温条件下采用批处理的方式,研究了MX-80膨润土对水溶液中U(VI)的吸附行为,考察了接触时间、pH值、离子强度、固体含量、腐植酸(HA)、富里酸(FA)和温度等因素的影响。实验结果表明,MX-80膨润土对U(VI)的吸附能力受pH和离子强度的影响较大。U(VI)从水溶液被吸附到MX-80膨润土上的速度相当快,并且其动力学吸附数据符合准二维速率方程。腐植酸可以显著增强MX-80膨润土对的U(VI)吸附,而富里酸对U(VI)的吸附没有显著影响。从不同温度下计算得到的MX-80膨润土对U(VI)的吸附热力学参数(△H0,△S0和△G0)可以看出,MX-80膨润土对U(VI)的吸附反应是自发的吸热反应。 | Xuemei Ren Suowei Wang Shitong Yang Jiaxing Li 任翠领 | 2013 | 腐植酸2013，，6： | 0 |
