The title compound sodium dysprosium(III) bis-[tungs-tate(VI)], NaDy(WO(4))(2), has been synthesized under high temperature solution growth (HTSG) conditions in air. The compound crystallizes with the scheelite structure and is composed of isolated WO(4) tetra-hedra ( symmetry) with one set of bond lengths and distorted [(Na/Dy)O(8)] dodeca-hedra ( symmetry; occupancy ratio Na:Dy = 1:1) with tw...
To the Editor: A recent article in PNAS by Asikainen and Werle (1) reports on the occurrence and morphology of ferromanganese nodules found in a New Hampshire lake. The authors offer data on the shapes, banding, composition, and distribution of the nodules and crusts. They also state that my paper (2) claims that the morphology of such nodules is controlled by elemental concentrations and that ...
babbitt is a white silvery alloy that composed of tin, lead, copper and antimony. this alloy is the most current bearing alloy in industrial applications. the characteristics of this alloy, such as high wearing resistance and low coefficient of friction, have converted it into a bearing cover. the target of this study is investigation on the effects of alloy elements on wearing and micro-struct...
In the title coordination polymer, {[Dy(C(10)H(13)N(2)O(8))]·3H(2)O}(n), the dysprosium(III) ion is coordinated by two N atoms and six O atoms from three different (carb-oxy-meth-yl)ethyl-ene-diamine-triacetate ligands in a distorted square-anti-prismatic geometry. The ligands connect the metal atoms, forming layers parallel to the ab plane. O-H⋯O hydrogen bonds further assemble adjacent layers...
Ground-state deformations, binding energies, and potential energy surfaces have been calculated for eveneven dysprosium isotopes between 160Dy and 180Dy in the framework of density-dependent Hartree-Fock calculations with BCS pairing correlations. Further deformed Hartree-Fock with angular-momentum projection and band-mixing calculations explore the yrast spectra of the nuclides approaching the...
In this report, dysprosium fluoride (DyF3) - a material for the preparation of (Dy) metal was prepared by fluorination oxide (Dy2O3) ammonium bifluoride (NH4HF2) reagent. The effect reaction time and temperature on formation salt has been studied. phase composition crystal structure obtained products were analysed X-ray diffraction (XRD). Thermal analysis techniques applied to determine range f...
