Correlation of Topography Measurements of NIST SRM 2460 Standard Bullets by Four Techniques

January 1, 2006
Author(s)
Jun-Feng Song, Theodore V. Vorburger, Thomas Brian Renegar, Hyug-Gyo Rhee, A Zheng, L Ma, John M. Libert, Susan M. Ballou, B Bachrach, K Bogart
Three optical instruments including an interferometric microscope, a Nipkow disk confocal microscope and a laser scanning confocal microscope are used for the measurements of bullet profile signatures of a NIST (National Institute of Standards and

Covariance-Based Uncertainty Analysis of the NIST Electrooptic Sampling System

January 1, 2006
Author(s)
Dylan F. Williams, Arkadiusz C. Lewandowski, Tracy S. Clement, C. M. Wang, Paul D. Hale, Juanita M. Morgan, Darryl A. Keenan, Andrew Dienstfrey
We develop a covariance matrix describing the uncertainty of mismatch-corrected measurements performed on the National Institute of Standards and Technology's electro-optic sampling system. This description offers a general way of describing the

Current Induced DomainWall Distortions

January 1, 2006
Author(s)
Willard C. Uhlig, John Unguris
We have directly imaged the spin transfer torque induced distortion of domain walls in current carrying ferromagnetic wires. Domain walls ranging from vortex walls in wide (1 m) wires, to transverse walls in narrow (100 nm) wires were studied. Scanning

Dielectric Study of the Anti-Plasticization of Trehalose by Glycerol

January 1, 2006
Author(s)
A Anopchenko, Tatiana Psurek, David L. VanderHart, Jack F. Douglas, Jan Obrzut
Recent measurements have suggested that the antiplasticizing effect of glycerol on trehalose can significantly increase the preservation times of proteins stored in this type of preservative formulation. In order to better understand the physical origin of

Dynamics of Wormlike Micelles in Elongational Flows

January 1, 2006
Author(s)
Philip A. Stone, Paul Dalhaimer, Dennis E. Discher, Eric J. Amis, Steven D. Hudson, Kalman D. Migler
Micelles formed of amphiphilic diblock copolymers may have applications in drug delivery and in understanding the physics of biological structures. Wormlike micelles, in particular, provide an opportunity to study the behavior of semiflexible rods in
