Syntheses and Crystal Structures of Three Ag(Ⅰ) Complexes with Chloro-phenylacetic Acid and Nitrogen
Three new coordination polymers {[Ag2(2,4-DCPA)(4,4?-bipy)2(NO3)]·(H2O)}n(1), [Ag(2,4-DCPA)(bpp)]n(2) and {[Ag(4-DCPA)(bpp)]·(H2O)}n(3), were synthesi
Thermoelectric(TE) materials can convert directly low-grade heat energy to electricity,and vice versa,which is highly expected to play an important role in the fu
Synthesis and Crystal Structure of a New Cadmium(Ⅱ) Coordination Polymer with Ethylenediaminetetraac
A new cadmium(Ⅱ) coordination polymer,namely,[KCd2(edta)I]n(1,H4edta = ethylenediaminetetraacetic acid),has been prepared and structurally characterized by sin
Accumulation of unfolded proteins in the endoplasmic reticulum (ER) results in ER stress, which subsequently activates the unfolded protein response that induce
本文独立地推导了考虑硬表面和软表面粗糙度影响的两体微切削磨损理论模型。这个模型直接利用表面轮廓高度分布密度函数进行计算,和现在生产实际中广泛应用的表面轮廓仪相衔接
采用宽板试验和带缺陷容器的爆破试验研究了加载中的屈服流动机制和断裂参量的变化。示出并解释了在宽板和容器上应力,应变和裂纹张开位移之间的关系。为了研究评定准则,对有关
Theoretical Calculation about the High Energy Density Molecules of Nitrate Ester Substitution Deriva
The nitrate ester substitution derivatives of prismane were studied at the B3LYP/6-311G** level. The sublimation enthalpies and heats of formation in gas phase
Hydrothermal Synthesis, Structural Characterization and Proton-conducting Property of a 3-D Framewor
A novel Zr-substituted polyoxometalate(POM) H2K3[Na6(H2O)9][Zr3Na3O3(H2O)3-(GeW9O34)2]·12H2O(1) has been made under hydrothermal conditions. 1 was characterized by
