| 1 | Statistical and thermodynamic properties of binary self-condensing vinyl polymerization显示文摘The thermodynamic properties of a binary self-condensing vinyl polymerization system consisting of monomers and inimers are investigated by the principle of statistical mechanics.In detail,in terms of two types of canonical partition functions constructed from different viewpoints,the equilibrium free energy,the law of mass action and the size distribution of hyperbranched polymers are obtained.As an application,the specific heat,equation of state and isothermal compressibility concerning the polymerization are given as well.To study the dimension of hyperbranched polymers in the system,a recursion formula satisfied by the(k+1)-th and k-th mean square radius of gyration is derived,and then the first,second and third radius of gyration under different solvent conditions are presented.The influences of the fraction of inimers,the conversion of vinyl groups and the solvent effect on the average dimension of hyperbranched polymers are discussed. | GU Fang WANG HaiJun ZHAO ZuoFei | 2011 | Science China Chemistry2011，54，3： | 5 |
| 2 | Microtremor-based analysis of the dynamic response characteristics of earth-fissured sites in the Datong basin, China显示文摘This study conducted microtremor testing along six survey lines that cross three typical earth fissures in the Datong basin to determine the dynamic response characteristics of earth fissure sites with regard to the Fourier amplitude spectrum,response spectrum,and Arias intensity.The results show the following.(1)The predominant frequency of an earth fissure site is mainly affected by the thickness and the shear wave velocity of the soil layer and is minimally effected by the presence of an earth fissure.(2)Earth fissures have a pronounced amplification effect on dynamic response.Fourier amplitude,response acceleration,and Arias intensity are high near an earth fissure and decrease with an increase in distance from the earth fissure,tending toward stability at a distance of 20 m.(3)The area that is seriously affected by this amplification is within 6-8 m of an earth fissure,and the general affected area is farther out than this,to a distance of 25 m.(4)New construction should be avoided in an area affected by the amplification,and existing buildings in general and seriously affected areas need to be reinforced to increase their seismic fortification intensity. | Xuan You Deng Yahong He Jia Chang Jiang Yan Zuofei Wu Wei | 2021 | Earthquake Engineering and Engineering Vibration2021，20，3： | 2 |
| 3 | The radius of gyration for a ternary self-condensing vinyl polymerization system显示文摘A ternary self-condensing vinyl polymerization(SCVP) system consisting of monomers, inimers and core initiators is studied by the principle of statistical mechanics. Starting from partition functions for polymerization that constructed from two different viewpoints, explicit expressions of the size distribution function(SDF), equilibrium free energy, and the law of mass action are obtained. For two types of hyperbranched polymers(HBPs) formed in the system, the first, the second, and the third mean-square radii of gyration(MSRG) are presented under various conditions. Furthermore, the solvent effect and excluded volume effect are taken into account in the calculation of the MSRG. With these results, the effects of monomers, inimers and core initiators on the spatial dimension of HBPs are discussed. It is shown that the competition between polymers with and without a core in the growing process results in a significant influence on the average properties of the system. | Xiaozhong Hong Zuofei Zhao Haijun Wang Xinwu Ba | 2015 | Science China(Information Sciences)2015，58，12： | 1 |

| 5 | Flying High Like a Kite显示文摘As a person who loves to travel and see the world,I have accumulated a wealth of knowledge on geography.Yet,when I was told that I would be sent to work in the Confucius Institute in Eritrea,I knew nothing about the country.Nor could I find much information on the Internet.With this ignorance,I landed in the country in the highlands of East Africa on the shores of the Red Sea in 2018.It didn’t bother me much,though,as I like the surprises the unknown might bring to me.So,I was both apprehensive and curious about the trip. | ZUO ZUOFEI | 2023 | ChinAfrica2023，15，2： | 0 |
| 6 | A Feel of Kunming In Africa显示文摘Life in Eritrea’s capital Asmara reminds Chinese teacher of China’s“spring”city I like to draw parallels between the life in foreign cities where I have lived and Chinese cities,which makes it eas-ier for me to remember them,and for my Chinese readers to get the sense of how they are like.When I was working in Georgia,I felt that its capital Tbilisi had a touch of Chongqing,a mountainous city in southwest China.Now after several years in Eritrea,the capital Asmara,with spring-like weather around the year,gives the feeling of living in Kunming. | ZUO ZUOFEI | 2022 | ChinAfrica2022，14，12： | 0 |
| 7 | Statistical thermodynamic properties of a new self-condensing vinyl polymerization system显示文摘A new self-condensing vinyl polymerization system consisting of *ABf-type inimers is studied by the principle of statistical mechanics. To obtain the relevant average properties of the system, a differential equation satisfied by the polymeric moment of interest is given, and as a result the zeroth, first, second, and third polymeric moments together with the size distribution function of hyperbranched polymers(HBPs) are explicitly presented. As an application of the method of statistical mechanics, several thermodynamic quantities such as the equilibrium free energy, law of mass action, isothermal compressibility, internal energy, and the specific heat associated with the polymerization are all derived. Furthermore, the scaling behavior of asymptotic size distribution function is discussed, by which a reasonable interpretation of the polydispersity index near the end of polymerization can be made. Also, the expressions of some structural parameters such as the numbers of inimers, terminal units, chain units, branched units, and the degree of branching(DB) are calculated. It is found that a high functionality is helpful to improve the DB of the resultant HBPs. These results show that the functionality f has a significant effect on the thermodynamic quantities and structural properties of HBPs. | Zuofei Zhao Yuanfeng Li Ning Yao Haijun Wang | 2015 | Science China Chemistry2015，58，9： | 0 |
