The Application of Optical Coherence Tomography to Problems in Polymer Matrix Composites

January 1, 2001
Author(s)
Joy Dunkers, Frederick R. Phelan Jr., D P. Sanders, M J. Everett, William H. Green, Donald L. Hunston, Richard~undefined~undefined~undefined~undefined~undefined Parnas
The Composites Group at the National Institute of Standards and Technology has found optical coherence tomography (OCT) to be a powerful tool for non-destructive characterization of polymer matrix composites. Composites often exhibit superior properties to

The Atom Laser

The Boundary Lubrication Properties of Model Esters

January 1, 2001
Author(s)
P M. McGuiggan
The friction of three chemically distinct esters was measured in order to determine how molecular architecture influences friction. The friction coefficients of mica surfaces separated by a thin film (

The Candela and Photometric and Radiometric Measurements

January 1, 2001
Author(s)
Albert C. Parr
The national measurement system for photometric and radiometric quantities is presently based upon techniques and a measurement chain that make these quantities traceable to a high accuracy cryogenic radiometer. The redefinition of the candela in 1979

The Effect of Pb Contamination on the Solidification Behavior of Sn-Bi Solders

January 1, 2001
Author(s)
Kil-Won Moon, William J. Boettinger, Ursula R. Kattner, C A. Handwerker, D J. Lee
This paper presents experimental results and theoretical calculations to evaluate the effects of Pb contamination on the solidification behavior of Sn-x mass Bi alloys (x = 5, 10, and 58 mass %). The pasty (mushy) range, the type of solidification path

The g Factor of the Bound Electron in Hydrogenlike Carbon

January 1, 2001
Author(s)
H Haeffner, N Hermanspahn, H -. Kluge, G Marx, W Quint, S Stahl, T Valenzuela, G Verdu, G Werth
The experimental determination of the magnetic moment of the bound electron in hydrogen-like ions is an important test of the theory of quantum electrodynamics in strong Coulomb fields. It represents a clean test of pure QED effects because it is not very

The GAMS 4 Flat Crystal Facility

The GAMS4 Flat Crystal Facility

January 1, 2001
Author(s)
Ernest G. Kessler, Maynard S. Dewey, R Deslattes, Albert Henins, H G. Borner, M Jentschel, H Lehmann
A high-resolution flat crystal gamma-ray facility, GAMS4, has been constructed at the high flux reactor at the Institut Laue-Langevin (ILL), Grenoble, France. The facility is located at the exit of a through-tube equipped to place sources in a neutron flux

The Influence of Grain Size on the Roughening Behavior of Al-Mg Alloys

January 1, 2001
Author(s)
Mark R. Stoudt, Richard E. Ricker
The discontinuouis plastic flow exhibited by numerous aluminum alloys presents significant challenges to the use of aluminum alloys in many automotive applications. The inhomogeneous morphology of the surface asperities generated during metal forming is

The Interdependent Networked Community Resilience Modeling Environment (IN-CORE): Science, Structure and Examples

January 1, 2001
Author(s)
John van de Lindt, Daniel Cox, Paolo Gardoni, Jong Lee, Jamie Padgett, Therese P. McAllister, Andre Barbosa, Harvey Cutler, Shannon van Zandt
ABSTRACT: Community resilience is the ability of a community to plan for, withstand, and recover from a natural hazard such as an earthquake or flood. Advancing community (or urban) resilience requires: (1) an understanding of how the physical
