Nano Research 2025年第1期18卷 157-163页

The cycloaddition reaction of CO_(2)with epoxide not only effectively reduces the concentration of CO_(2)in the atmosphere,but also has excellent industrial application value and up to 100%atom utilization,but there are difficulties in separation and recovery of traditional homogeneous catalysts,harsh reaction conditions of traditional heterogeneous catalysts,and activation of CO_(2)*** this paper,an easily synthesized heterogeneous catalyst CeNCl/C was used to catalyze the cycloaddition reaction of CO_(2)with styrene oxide,with a high yield of 92.7%,a high selectivity of 96.7%,a turnover numbers(TON)value of 349,and a good stability demonstrated in six cycle tests(equivalent to 216 h of testing).Through comprehensive studies,it was shown that CeNCl/C contains Lewis acid-base centers as active centers,which can effectively reduce the energy barrier required for ring opening of the reaction substrate,enhance the adsorption and activation of CO_(2),and promote the formation of intermediates,which led to the acquisition of excellent catalytic activity.

目的:通过将筛选的UL29shRNA表达质粒与抗病毒药物阿昔洛韦(ACV)的抗病毒效果及细胞毒性进行比较,探讨RNA干扰在细胞水平上对HSV-2病毒的抑制效果。方法:将筛选的干扰效果最好的表达质粒UL29-shRNA1641作为RNA干扰组与抗病毒药ACV进行对HSV-2的抑制效果的比较研究,分为RNAi组、ACV组和RNAi+ACV组。采用实时荧光定量PCR检测UL29mRNA的相对表达量,Karber法检测细胞上清液中病毒滴度的变化、蛋白印迹法(Western blot)检测ICP8的相对表达量,对RNAi与ACV抑制效果进行比较,通过WST-1(Water-Soluble Tetrazolium-1)法对质粒转染复合物(质粒+转染试剂)和ACV的细胞毒性进行比较。结果:RT-PCR检测三组mRNA的相对表达水平,其中RNAi组UL29基因相对表达量高于ACV组(P<0.05);RNAi+ACV组UL29基因相对表达量明显低于RNAi组和ACV组(P<0.05)。Karber法检测三组细胞上清液病毒滴度表明,RNAi组病毒滴度高于ACV组(P<0.05),RNAi+ACV组的病变病毒滴度明显低于RNAi组和ACV组(P<0.05)。Western blot检测ICP8相对表达量,ACV组的ICP8(UL29编码的单链DNA结合蛋白,主要作用是在HSV-2 DNA复制过程中与复制叉产生了单链DNA结合,防止其重新配对形成ds DNA或被核酸酶降解)相对表达量比RNAi组低(P<0.05)。RNAi+ACV组ICP8相对表达量降低最为明显,与ACV组和RNAi组相比有显著差异(P<0.05)。WST-1法对转染复合物与ACV的细胞毒性进行比较,其中RNAi中质粒和转染试剂对细胞的毒性明显小于ACV。结论:在RNAi与ACV对HSV-2抑制效果的比较中,ACV要好于RNAi,两者联合使用的抑制效果好于单独使用RNAi或ACV。在抑制效果都较好的情况下比较,RNAi中使用的质粒与转染试剂对细胞的影响比ACV小。

Experimental analysis of crack tip fields in rubber materials under large deformation

引用

Acta Mechanica Sinica 2012年第2期28卷 432-437页

作者： Xia xiao Hai-Peng song Yi-lan Kang xiao-Lei Li xiao-Hua Tan Hao-Yun Tan Department of Mechanics Tianjin University300072 TianjinChina School of Mechanical Engineering Tianjin Polytechnic University300387 TianjinChina Hebei University of Technology 300401 TianjinChina

A three-nested-deformation model is proposed to describe crack-tip fields in rubber-like materials with large deformation. The model is inspired by the distribution of the measured in-plane and out-of-plane deformation. The in- plane displacement of crack-tip fields under both Mode 1 and mixed-mode （Mode I-II） fracture conditions is measured by using the digital Moir6 method. The deformation character- istics and experimental sector division mode are investigated by comparing the measured displacement fields under differ- ent fracture modes. The out-of-plane displacement field near the crack tip is measured using the three-dimensional digital speckle correlation method.
