Angular-Momentum Resolved Partial Density of States of Rutile TiO 2 : Theory and Experiment

February 19, 2017
Author(s)
Joseph Woicik, E J. Nelson, L Kronik, M Jain, J R. Chelikowsky, D Heskett, L E. Berman, G S. Herman
Using the method of site-specific valence x-ray photoelectron spectroscopy (SSVKPS), we have experimentally determined the Ti and O partial density of occupied valence states of rutile TiO2. Excellent agreement with ab initio local density approximation

Anomalous Lattice Expansion of Coherently Strained SrTiO 3 Thin Films Grown on Si(001) by Kinetically Controlled Sequential Deposition

February 19, 2017
Author(s)
Joseph Woicik, H Li, P Zschack, E Karapetrova, P Ryan, C R. Ashman, C S. Hellberg
X-ray diffraction has been used to study the epitaxy and lattice expansion of SrTiO3 thin films grown on Si(001) by kinetically controlled sequential deposition (KCSD). Unlike films grown by traditional molecular beam epitaxy (MBE), these films have an in

Applications of Ceramics for Healthcare: The Future Has Begun

February 19, 2017
Author(s)
Grady S. White
Dramatic improvements in our understanding of how biological systems work, diseases initiate, and illnesses progress have given rise to the expectation that many of these ailments can be cured, perhaps even in their precursor states, as new tools are

Assessment of Powder Characterization Methods for Advanced Ceramics

February 19, 2017
Author(s)
Lin-Sien H. Lum
This report summarizes the results of an international round robin study on advanced ceramic powders. Thirty-four laboratories from Belgium, Germany, Japan, Sweden and the U.S. representing industrial, academic and government research organizations

Boundary Lubricated Friction Experiments With Coarse Surface Texture

February 19, 2017
Author(s)
Jorn Larsen-Basse, L K. Ives, Stephen M. Hsu
Low-speed friction experiments were conducted under boundary lubrication in a pin-on-disk tester. The 304 stainless steel disk had smooth areas alternating with areas of coarse surface texture consisting of indents or macroscopic grooves, 0.3-0.4 mm in

CD ROM Guide for NIST Crystal Data NIST Standard Reference Database 3

February 19, 2017
Author(s)
Vicky L. Karen, S L. Young, Alan D. Mighell
The NIST Crystallographic Data Center collects, evaluates and disseminates data on solid-state materials. NIST Crystal Data is a comprehensive database with chemical, physical and crystallographic information on all classes of well-characterized substances

Characterization of the Mirror Region With Atomic Force Microscopy

February 19, 2017
Author(s)
Sheldon M. Wiederhorn, Jose Lopez-Cepero, Jay S. Wallace, Jean-Pierre Guin, Theo Fett
In this paper we use atomic force microscopy to investigate the roughness of the mirror region in silica glass. We demonstrate a decrease in surface RMS Roughness from about 0.5 nm to about 0.4 nm with increasing stress intensity factor (0.5KIc to about 0

Combinatorial Tools for Inorganic Thin Films

February 19, 2017
Author(s)
Peter K. Schenck, Debra L. Kaiser
We report the deveopment of a novel dual beam - dual target pulsed laser deposition (PLD) system for the production of compositionally-graded library films for combinatorial thin film materials research. In-situ process monitoring, including high-speed
