Synthesis pretreatment and characterization of a magnetic layered double hydroxides fluorescent probe

引用

Chinese Chemical Letters 2014年第6期25卷 923-928页

作者： Li-e.Dong guo-jing Gou Xue-Qin jin Min Zhang Medical Chemistry Department School of Basic MedicalNingxia Medical University

Using magnetic layered double hydroxide （MLDH） as carrier of fluorescein （FLU）, a fluorescent composite of MLDH-FLU was prepared via intercalation reaction of ion change. The crystal properties of MLDH-FLU were investigated through XRD, IR, TeM and TG-DSC characterization. It is shown that the crystal type of MLDH-FLU composite matched well with R-hexagonal crystal system of MLDH, with crystal cell parameters of a, c and channel height h equal to 0.3199, 2.411 and 0.3267 nm respectively. The superabundant pigment adsorbed outside the composite should be cleared before interference with cells, but excessive wash would decrease stability and cause crystal phase transformation of MLDH.

基于计算滑坡概率的蒙特卡罗法,该文以黄土高原地区的榆林市朝阳路滑坡为研究对象,通过野外调查、室内试验和综合研究,分析了黄土黏聚力和内摩擦角等多种条件下的安全系数分布、失稳概率和可靠度,探讨了参数相关性对于滑坡可靠度的影响,并进行了对黏聚力和内摩擦角的敏感性分析。研究发现,该滑坡为黄土高原区典型降雨诱发型,当同时考虑黏聚力和内摩擦角的变化时,滑坡可靠度指数为1.35,失稳概率为8.83%,安全系数介于0.794~1.305;与同单一变量情况下相比,多个变量分析计算的可靠性指数显著减小,标准偏差明显增大,滑坡失稳概率升高;不同参数相关性条件下,滑坡失稳概率、可靠度和安全系数的标准偏差不同;滑坡的稳定性系数对于不同土性参数的敏感性存在差异。该文基于研究结果提出了相应的防治措施,为黄土高原地区滑坡防治和危险性评估提供科学依据。
