Chemical Research in Chinese Universities 1993年第3期9卷 194-200页

作者： LIU De-xin, CUI Xue-gui, LI Shu-ian, LI Xiao-yan and SUN hong-jian (Department of Chemistry, Shandong University, Jinan, 250100)

The crystal structure of the title compound [Cu (o-vanillin-ethylenediamine) (h2O)] is described. The complex crystallizes in the orthorhombic system, space group Pbn21 with formula = CuC18h20N2O5, cell dimensions are: a = 0.7490(3) nm, b = 0.9256(2) nm, c=2. 4691(6) nm, V=1.712 nm3, Z = 4, Dc=l.51 g/cm3. The kinetics of thermal decomposition of the complex was studied under the non-isothermal condition by TG. Kinetic parameters were obtained from the analysis of the TG, DTG curves by integral and differential methods. By comparison of the kinetic parameters, the most probable mechanism function is f(α) = (3/2) (1-α)[-ln(1-α)]1/3, and the mathematical expression for the kinetic compensation effect is lnA = 0. 201E+0. 531.

The design criteria for metal-organic frameworks(MOFs)have been established by evaluating the rela-tionship between their key characteristics and magnesium-ion conductivity based on three types of sec-ondary building blocks(Zn_(4)O(CO_(2))_(6):MOF-5 and MOF-177;Cu_(2)(CO_(2))4:MOF-199,MOF-143,MOF-14,and MOF-399;Cu_(2)O_(2)(CO_(2))2:Cu-MOF-74)to achieve pseudo-solid-state magnesium-ion *** found that open-metal sites and channel layouts play a pivotal role in promoting magnesium-ion transport dy-namics at reduced activation energy,transforming MOF scaffolds into ionic-channel analogs.X-ray ab-sorption spectroscopy combined with Raman and Fourier-transform infrared spectroscopy predicted the chemical environment,solvents,and anions that occupied coordinatively unsaturated metal *** chemical compositions of electrolytes determined by^(1)h-NMR(nuclear magnetic resonance)and organic elemental analysis confirmed that isoreticular expansion increases the molar percentage of charge carri-ers,providing high *** current research systematically reveals the impacts of different MOF characteristics on ionic conduction performance,paving the way for the construction of a new class of fast and selective multivalent-ion pseudo-solid electrolytes.

目前随着我国经济的发展,企业国际化程度逐步提高,特别是铁路企业实施"走出去"战略,在中国中铁工程总公司国际化战略的指导下,海外业务已经取得了很大的进步,涉足海外房地产、工程承包、矿业开发等等。迅速扩大的海外业务,带来了许多风险,比如:政治、法律、文化、贷款、汇率等风险,其中汇率风险是风险管控中不可或缺的一环,并将其纳入到战略规划中去,实现风险的事前处理。在风险识别的基础上,建立风险防范的组织保证,有效地对汇率风险进行事前、事中、事后的全面管控,尽可能将风险消灭在战略决策阶段,对于不可避免的风险,尽可能减少损失。只有这样企业才能够纵横四海、决胜千里之外!
