  1. Effect of Axial Magnetic Field on Thermocapillary Convection with Bidirectional Temperature Gradients in a Shallow Annular Pool

    This simulation is based on the Czochralski model. The thermocapillary convection is harmful to obtaining high-quality crystal. The effect of axial magnetic field on themocapillary convection is reported. The hydrothermal waves and critical temperature gradient would be changed by the applied magnetic field. The transition of flow could be different under various condition. This investigation could be useful to the crystal growth.

  2. Intermediate-Valence Intermetallic Phase YbIn1–xAu1+x (x = 0-0.3) : Dedicated to David C. Johnson on his 60th birthday

    The phase YbIn1–xAu1+x has a homogeneity range for 0.0 ≤ x ≤0.3 (770 K). Ionic interaction between the ytterbium and gold is supported by the dative bonding Au[RIGHTWARDS ARROW]Yb. Intermediate valence for Yb increases with increasing x. The 197Au Mössbauer spectra show a superposition of the signals for Au1 (δ = 3.31 mm s–1) and Au2 (δ = 5.37 mm s–1), indicating auridic character of gold.

  3. Optical and Multiferroic Properties of Gd-Co Substituted Barium Hexaferrite

    Gd-Co substituted M-type barium hexaferrite, Ba1-xGdxCoxFe12-xO19 has been synthesized using sol - gel method. UV Vis - NIR have demonstrated that the band gap of as prepared samples increases with substitution. VSM analysis has revealed that coercivity and saturation magnetization depend on substitution. The prepared material can be used as a recording media due to its high surface area, high coercivity and saturation magnetization.

  4. Implications of Crystal Structure on Organotin Carboxylate Photoresists

    Meredith C. Sharps, David A. Marsh, Lev N. Zakharov, James E. Hutchison and Darren W. Johnson

    A series of five organotin carboxylate clusters of the type [RSn(O)O2CR’]6 have been synthesized and examined by single crystal X-ray diffraction. The crystal structures have been compared with regards to the steric and intermolecular forces dictated by the ligand groups as a means to understand how these same factors affect irradiation trends in lithography of thin films. Trends found are compared to other factors that may also dictate resist formation.

  5. One-Step Formation of 3D Alternating-Layer Structures Composed of Plates of Nanocrystalline Bismuth Oxide and Spherical Particles of Metallic Bismuth

    Version of Record online: 24 JUL 2017 | DOI: 10.1002/crat.201700099

    The authors demonstrate a possibility of synthesizing a periodic heterostructure consisting of layers of nanocrystalline β-bismuth oxide and layers of spherical particles of metallic bismuth in a single step by conducting partial reduction of [Bi6O5(OH)3](NO3)5·3H2O in benzyl alcohol. The mechanisms governing the interface formation during the synthesis of the β-Bi2O3/spherical Bi alternating-layer structure are discussed.
