Thermodynamic, Transport, and Chemical Properties of Reference JP-8

July 14, 2010
Author(s)
Thomas J. Bruno, Marcia L. Huber, Arno R. Laesecke, Eric W. Lemmon, Mark O. McLinden, Stephanie L. Outcalt, Richard A. Perkins, Beverly L. Smith, Jason A. Widegren
This report contains a summary of research conducted to develop a standard or accepted set of thermophysical properties for the aviation kerosene, JP-8. This report is the culmination of a three year effort that included the participation of most of the

Thermal Decomposition of RP-2 with Stabilizing Additives

May 7, 2010
Author(s)
Jason A. Widegren, Thomas J. Bruno
The thermal decomposition of RP-2 and mixtures of RP-2 with four different additives has been investigated. The mixtures with RP-2 contained one of the following: 5 % /trans/-decahydronaphthalene (decalin); 5 % 1,2,3,4-tetrahydronaphthalene (tetralin); 5 %

Kinetics of the Thermal Reaction of H Atoms with Propyne

April 15, 2010
Author(s)
Claudette M. Rosado-Reyes, Jeffrey A. Manion, Wing Tsang
The reaction of hydrogen atoms with propyne(CH≡CCH3) has been investigated in a heated single pulse shock tube at temperatures of 870-1145K and pressures of 2-9 bar. Stable products from various reaction channels (terminal and non-terminal H addition, and

Density and Speed of Sound Measurements of 1- and 2-Butanol

November 12, 2009
Author(s)
Stephanie L. Outcalt, Arno R. Laesecke, Tara J. Fortin
The density and speed of sound of 1- and 2-butanol have been measured using two instruments. Both instruments use the vibrating-tube method for measuring density. Ambient pressure (83 kPa) density and speed of sound measurements were carried out from 278

Reference measurements of Hydrogen's Dielectric Permittivity

August 10, 2009
Author(s)
James W. Schmidt, Michael R. Moldover, Eric F. May
We used a quasi-spherical cavity resonator to measure the relative dielectric permittivity ε r of H 2 at frequencies from 2.4 GHz to 7.3 GHz, at pressures up to 6.5 MPa, and at the temperatures 273 K and 293 K. The resonator was calibrated using auxiliary

A Ferroelectric Oxide Directly on Silicon

April 17, 2009
Author(s)
Joseph C. Woicik, Maitri P. Warusawithana, Cheng Cen, Charles R. Sleasman, Yulan Li, Jeffery Kluga, Lena F. Kourkoutis, Hao Li, Li-Peng Wang, Michael Bedzyk, David A. Muller, Long-Qing Chen, Jeremy Levy, Darrell G. Schlom
Silicon and silicon dioxide form what is arguably the most important technological interface. With the end of Moore s-law scaling for silicon fast approaching, alternatives to silicon dioxide are being pursued that may enable new device architectures and

An Independent Measurement System for Testing Automotive Crash Warning Systems

April 2, 2009
Author(s)
Sandor S. Szabo, Joseph A. Falco, Richard J. Norcross
This report describes the National Institute of Standards and Technology's role in the Integrated Vehicle-Based Safety Systems (IVBSS) program, a four-year safety initiative sponsored by the United States Department of Transportation (U.S. DOT) to develop

Research at NIST-Boulder on the Compatibility of Hydrogen and Carbon Steels

February 18, 2009
Author(s)
Nicholas Nanninga
The demand for gaseous hydrogen fuel is expected to necessitate a consistent supply of hydrogen that can only be delivered through networks of existing and new pipelines and storage units. The focus of the Hydrogen Project at the National Institute of

Density and Speed of Sound Measurements of Jet A and S-8 Aviation Turbine Fuels

January 27, 2009
Author(s)
Stephanie L. Outcalt, Arno R. Laesecke, Malte B. Freund
The density and speed of sound were measured for three compositions of aviation jet fuel A, and a synthetic fuel (S-8) derived from the Fischer-Tropsch process. Measurements of density and speed of sound were carried out at ambient pressure (83 kPa) with a
