  Ferroelectric Thin Films of Bismuth-Containing Layered Perovskites: Part II, PbBi₂Nb₂O₉

  摘要：

  Ferroelectric thin films of bismuth‐containing layered perovskite PbBi2Nb2O9 have been prepared by a metalorganic decomposition (MOD) method. Random and highly c‐oriented films of the same starting composition have been obtained under different intermediate‐ and high‐temperature heat treatments. A comparison of their crystallization and properties with those of Bi4Ti3O12 films reveals similar trends that are common to bismuth‐containing Aurivillius compounds. Heterogeneous nucleation of the perovskite phase either on the pyrochlore (444) plane because of lattice matching or on the substrate surface because of lower interfacial energy is proposed as the cause of orientation selection during crystallization. The different thickness of the pseudoperovskite subunits in these layered compounds may be responsible for the systematic difference in the anisotropic ferroelectric properties. Smaller polarization and higher coercive field are expected for PbBi2Nb2O9, which has thinner pseudoperovskite units than Bi4Ti3O12.

  Phase diagrams and optical properties of binary liquid-crystal systems of cobalt(II) caprylate with a divalent metal caprylate

  摘要：

  Phase equilibria in the binary systems of cobalt(II) caprylate with a divalent metal (lead, cadmium, or zinc) caprylate were studied by differential thermal analysis and polarization microscopy, and the concentration and temperature ranges of the existence of liquid crystals and glasses were determined. Continuous or boundary smectic liquid-crystal solutions were found to form in all the systems. The temperature and concentration dependences of the electronic absorption spectra of liquid crystals and glasses in binary systems based on cobalt caprylate were investigated.

  phases and mesophases. The crystal structures at room temperature of all of the members of the series are now solved, showing the existence of two polymorphic forms in the room temperature crystal phase, different to short and long-chain members. Only nonanoate and decanoate present both forms, and this polymorphism is proven to be monotropic. At higher temperature, these compounds present a solid mesophase

• The Solventless Syntheses of Unique PbS Nanowires of X-Shaped Cross Sections and the Cooperative Effects of Ethylenediamine and a Second Salt
  作者：Jing Chen、Ling Chen、Li-Ming Wu

  DOI：10.1021/ic7008336

  日期：2007.9.1

  Unique PbS nanowires with x-shaped cross sections, with diameters in the range of 300-800 nm with an average of 598 nm (sigma = +/- 21.7%), and lengths of up to several tens of micrometers, have been made by a solventless method. Such nanowires show high adsorptivities of the PbS nanooctahedra, which can be washed off by ultrasound. The suitable precursor is obtained from a Pb(NO3)(2)/Octanoate/ethylenediamine/dodecanethiol molar ratio of 1:21: 1.6, and the PbS nanowires are produced by the thermolysis of such precursors at 280 degrees C for 1 hour. The X-ray diffraction, scanning electron microscopy, and transmission electron microscopy characterizations of the products and the keys of the morphological control have been reported. For the formation of such products, two cooperative effects are found to be crucial, the roles of ethylenediamine and a second salt, lead octanonate.
