Thermodynamic Properties of Air at Pressures to 2000 MPa

August 1, 1998
Author(s)
William M. Haynes, Eric W. Lemmon, Daniel G. Friend, R Jacobsen
A new formulation for the thermodynamic properties of standard dry air at pressures to 2000 MPa has been developed. This formulation, which can be used at temperatures from the freezing liquid line to 2000 K, is based on comprehensive experimental

Anti-Drain Requirements for Retail Motor-fuel Dispensers

April 26, 2012
Author(s)
Marc A. Buttler
Two of the most fundamental components that can be found in any liquid fuel dispenser are the measuring device and the hose that transports the metered product to the consumers vehicle. The fuel that fills the volume of space in between the measuring

Information: A Key to Supply Chain Performance

December 1, 2002
Author(s)
Albert W. Jones, Larry H. Reeker, A S. Deshmukh
This paper makes serveral critical points related to the intrinsic nature of the relationship between information and performance in supply chains. It highlights the co-dependence of information and supply-chain management decisions, stresses the impact of

Using a High-Value Resistor in Single-Electron Counting Measurements

June 1, 2002
Author(s)
Randolph Elmquist, Neil M. Zimmerman, William Huber
An experiment using a high-value cryogenic resistor is proposed, with the aim of improving the experimental link between three quantum electrical standards. This technique is new in its approach and does not require feedback from either a voltage detector

Autonomous cementitious materials formulation for critical infrastructure repair

January 17, 2024
Author(s)
Howie Joress, Rachel Cook, Austin McDannald, Mark Kozdras, Jason hattrick-simpers, Aron Newman, Scott Jones
Despite the long history of cement and concrete, there are still large gaps in fundamental knowledge of their properties development. The dire need for improved cementitious repair materials, requires a revolution in the way they are formulated and tested

Quantum information processing and multiplexing with trapped ions

January 1, 2003
Author(s)
David J. Wineland, Dietrich G. Leibfried, B. L. DeMarco, V Meyer, M A. Rowe, A Ben kish, Murray D. Barrett, Joseph W. Britton, J Hughes, Wayne M. Itano, Branislav M. Jelenkovic, Christopher Langer, D Lucas, Till P. Rosenband
We report experiments on coherent quantum-state synthesis and control of trapped atomic ions. This work has the overall goal of performing large-scale quantum information processing; however, such techniques can also be applied to fundamental tests and

High-efficiency Coherence-Preserving Harmonic Rejection with Crystal Optics

September 1, 2018
Author(s)
Fan Zhang, Andrew J. Allen, Lyle E. Levine, Gabrielle G. Long, Ivan Kuzmenko, Jan Ilavsky
We report a harmonic rejection scheme based on the combination of Si (111) monochromator and Si (220) harmonic-rejection crystal optics. This approach is of importance to a wide range of X- ray applications in all three major branches of modern X-ray

Polymers in Particulate Systems: Properties and Applications

November 1, 2001
Author(s)
Vincent A. Hackley, P Somasundaran, J A. Lewis
Soluble polymers are key additives for a broad range of industrial and biomedical applications, including advanced ceramics, mineral separations, high performance cement, and bioceramic coatings and composites. Such species find widespread use as

Visualization and Quantification of Forced In-Plane Flow Through Deformable Porous Media

October 12, 2021
Author(s)
H L. Friedman, R A. Johnson, V Gussev, A V. Neimark, D R. Salem, Richard~undefined~undefined~undefined~undefined~undefined Parnas
Fluid flow in liquid molding processes and in other applications involving porous media is often characterized with a permeability tensor and modeled by d'Arcy's law. The permeability is a sensitive function of pore structure which, in deformable materials

A Q-band free-space characterization of carbon nanotube composites

September 19, 2016
Author(s)
Ahmed M. Hassan, Jan Obrzut, Edward Garboczi
We present a free-space measurement technique for non-destructive non-contact electrical and dielectric characterization of nano-carbon composites in the Q-band frequency range of 30 GHz to 50 GHz. The experimental system and error correction model

The spectrum of Fe II

January 1, 2013
Author(s)
Gillian Nave, S Johansson
The spectrum of singly-ionized iron (Fe II) has been recorded using high-resolution Fourier transform and grating spectroscopy over the wavelength range 900 Å to 5.5 μm. The spectra were recorded in high-current continuous and pulsed hollow cathode

Calibrated nanoscale capacitance measurements using a scanning microwave microscope

November 2, 2010
Author(s)
H P. Hubner, M. Moertelmaier, Pavel Kabos, M. Fenner, C Rankl, Atif A. Imtiaz
A scanning microwave microscope (SMM) for spatially resolved capacitance measurements in the attofarad-to-femtofarad regime is presented. The system is based on the combination of an atomic force microscope (AFM) and a performance network analyzer (PNA

Micro-Feature Metrology

May 1, 2005
Author(s)
Bala Muralikrishnan, Jack A. Stone Jr., John R. Stoup
This presentation focuses on three aspects of micro-feature metrology novel applications that drive research and commercialization, capabilities and limitations of existing sensors and techniques, and finally a summary of recent research including ongoing
