Synthesis and Single-Crystal X-Ray Diffraction Studies of New Framework Substituted Type II Clathrates, Cs 8 Na 16 Ag x Ge 136-x (x 7)

April 13, 2007
Author(s)
Matthew Beekman, Winnie Wong-Ng, James A. Kaduk, Alexander J. Shapiro, George S. Nolas
New inorganic type II clathrates with Ag atoms substituting for framework Ge atoms, Cs8Na16AgxGe136-x (x = 0, 5.9, and 6.7), have been synthesized by reaction of the pure elements at high temperature. Structural refinements have been performed using single

A Study of the Packing Density and Molecular Orientation of Bimolecular Self-Assembled Monolayers of Aromatic and Aliphatic Organosilanes on Silica

April 12, 2007
Author(s)
M B. Smith, K Efimenko, Daniel A. Fischer, S E. Lappi, P E. Kilpatrick, Jan Genzer
Bimolecular self-assembled monolayers (SAMs) of aromatic and aliphatic chlorosilanes were self-assembled onto silica and their characteristics were established by contact angle measurement, near-edge X-ray adsorption fine structure spectroscopy, and

Phase Relations in the Ba-Y-Cu-O Films on SrTiO3 for the -Ex Situ BaF2- Process

March 5, 2007
Author(s)
Winnie K. Wong-Ng, Makoto Otani, Lawrence P. Cook, Mark D. Vaudin, James P. Cline, Ron Feenstra, T G. Holesinger
In situ x-ray diffraction was used to establish the phase relations in high-Tc superconductor Ba–Y– Cu–O films grown on SrTiO3 through the ex situ BaF2 process. These relations differ from bulk equilibrium phase assemblages in the BaO–Y2O3–CuOx system. In
