Polymerization of C60 is realized under high temperature and high pressure. X-ray diffraction reveals a rhombohedral lattice structure in the product, and solid-state ^13C nuclear magnetic resonance spectroscopy confirms the formation of sp^3 bonds between C60 molecules. Specific heat is then measured over the temperature range of 300-2 K. It is found that its specific heat values are significantly less than those in fullerite within the region of 80-2K, and this huge reduction is attributed to the suppression of intermolecular librational modes in polymerized C60. An excellent fit to the experimental data over the entire temperature range is provided by a model, which needs to include only three-dimensional and two-dimensional translational modes in various contributions at different temperatures. 相似文献

An iron(Ⅱ) coordination polymer, Fe(Haip)2(H2O)2n (1, Haip = 5-ammoniumiso-phthalato), has been hydro/solvothermally synthesized and characterized by single-crystal X-ray diffraction, elemental analysis, infrared spectrum and magnetic measurement. Compound 1 crystalizes in monoclinic, space group P2/c with a = 6.9874(14), b = 9.960(2), c = 12.894(4), β = 117.47(2)°, Fe(C8H6NO4)2(H2O)2 , Mr = 452.16, V = 796.2(3)3 , Z = 2, D c = 1.886 g·cm-3 , μ = 1.017 mm-1 , F(000) = 464.0, 2.71<θ<28.42°, R = 0.0307, wR = 0.0840 and S = 1.005. Single-crystal X-ray diffraction analysis reveals that 1 features an infinite one-dimensional loop-like chain structure and Haip ligand in 1 is of zwitterionic form. Magnetic measurement results show the dominated ferromagnetic interactions among FeⅡ atoms. 相似文献

<正>为了降低由于科技政策信息与创新主体需求之间匹配度较低引起的推送效果差的问题,提出基于数据挖掘技术的科技政策信息推送算法。首先利用Python组件对信息中的词汇进行预处理,利用深度挖掘的方式确定数据簇的中心以及半径,将其作为用户信息需求匹配的参照,将用户信息与数据簇之间建立匹配关系,将相似度最高的数据簇中对应的信息作为推送内容,完成信息推送。通过实验测试所提方法的推送效果,结果表明其推送的误差均值在10%以内,用户满意度均值为94.13%,错误推送率仅为0.93%。 相似文献
