Abrasive Machining of Glass-Infiltrated Alumina with Diamond Burs

February 19, 2017
Author(s)
L Yin, L K. Ives, S Jahanmir, E D. Rekow, E Romberg
The abrasive machining characteristics of a glass-infiltrated dry-pressed alumina used for fabrication of all-ceramic dental crowns are investigated using a high-speed dental handpiece and diamond burs containing supercoarse (180 m), fine (40 m), and

ACerS-NIST Phase Equilibria Diagrams Volume XIV Oxides

February 19, 2017
Author(s)
Robert S. Roth, Terrell A. Vanderah
This volume is the fourteenth of the topically-oriented series of phase diagram compilations and the tenth to appear since the National Institute of Standards (NIST) and the American Ceramic Society (ACerS) embarked on a jointly-sponsored expanded Ceramic

Advances in Atomic Structure Calculations

February 19, 2017
Author(s)
Charlotte F. Fischer
Correlation and relativistic effects are both needed for accurate atomic structure calculations of energy levels and their atomic properties. For transition probabilities between low-lying levels of a spectrum, accurate wave functions for the outer region

Advances in Thermal Imaging Technology in the First Responder Arena

February 19, 2017
Author(s)
Francine K. Amon, Nelson P. Bryner
The Building and Fire Research Laboratory (BFRL) at the National Institute of Standards and Technology (NIST) has been conducting research that will provide a quantifiable physical and scientific basis upon which industry standards for imaging performance

Aerodynamic Damping in the Along-Wind Response of a Tall Building

February 19, 2017
Author(s)
Rene D. Gabbai, Emil Simiu
We present an estimate of the aerodynamic damping that affects the along-wind response of an isolated tall building in suburban terrain. The evaluation uses measurements of the external pressures on the windward and leeward faces under wind normal to a

AEX XML Schema Reference Guide

February 19, 2017
Author(s)
Mark E. Palmer, M Burns, T L. Teague, Mary Turton, Rurik Turton
The AEX XML Schema Reference Guide summarizes the design principles and the structures of the AEX (Automating Equipment Information eXchange) XML schemas, guidance for making schema extensions and usage guidance for those who wish to deploy the AEX schemas

Alert Categorization, Revision 1.0

February 19, 2017
Author(s)
Alan B. Vinh
There are many types of sensor devices available in today s market with many still in development. These devices send signals representing the detection of entities such as temperature and smoke. With the availability of sensor devices monitoring various

An Exception to Amontons' Law: The Friction of Carbon Surfaces in Air

February 19, 2017
Author(s)
P M. McGuiggan
The friction of carbon has been of much interest in recent years due to its good tribological properties. These properties include high wear resistance, high hardness, low friction coefficients, and low corrosion. 1 In computer hard disks, the magnetic

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 a 3D-Printed Aluminum Corrugated Feed Horn at 118.7503 GHz

February 19, 2017
Author(s)
Josh Gordon, David R. Novotny, Ronald C. Wittmann, Michael H. Francis, Jeffrey R. Guerrieri, Periasamy Lavanya, Albin Gasiewski
All-metal 3D printing is investigated as a viable option for millimeter wave applications. 3D printing is finding applications across many areas and may be a useful technology for antenna fabrication. The ability to rapidly fabricate custom antenna

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

Assessment of the Structural Fire Performance of Buildings

February 19, 2017
Author(s)
Richard W. Bukowski
The fire-induced collapse of the World Trade Center (WTC) buildings 1, 2, and 7 on 11 September 2001 demonstrated the need for engineering methods to predict the structural fire performance of buildings when subjected to arbitrary design fires and to
