Strengths and Limitations of Surface Texture Characterization Techniques

January 1, 2001
Author(s)
Theodore V. Vorburger
Surface finish is important to the function of a wide range of industrial components including highways, ship hulls and propellers, mechanical parts, semiconductors, and optics. Hence, many documentary standards have been developed for specifying surface

Structured Polymeric Templates: Combinatorial Probes for Cellular Response

January 1, 2001
Author(s)
A Sehgal, Jack F. Douglas, Francis W. Wang, Carl G. Simon Jr., Alamgir Karim, Eric J. Amis
Novel high-throughput gradient methods have been developed to generate a range of surface structures by dewetting and phase separation on chemically patterned substrates. The research is motivated by an increasing awareness in the biomedical industry and

Summary Proceedings: Legal Metrology Seminar for the Americas

January 1, 2001
Author(s)
S E. Chappell, Charles D. Ehrlich, Kenneth S. Butcher
This paper provides a report on the Legal Metrology Seminar for the Americas that was held in conjunction with the 85th annual meeting of the National Conference on Weights and Measures (NCWM) in Richmond, VA, from July 16 through July 20, 2000. The

Surface and interface effects in the growth of giant magnetoresistance spin valves for ultrahigh-density data-storage applications

January 1, 2001
Author(s)
William F. Egelhoff Jr., P J. Chen, Cedric J. Powell, Robert McMichael, Mark D. Stiles
The current generation of hard disk drives use Giant Magnetoresistance (GMR) spin valves as the read-head because the GMR effect is currently the most sensitive way to detect magnetic fields at submicron length scales and data rates of approximately equal}

Synchronization and Phase Lock of Two Mode-Locked Femtosecond Lasers

January 1, 2001
Author(s)
R K. Shelton, L -. Ma, H C. Kapteyn, M M. Murnane, J L. Hall, Jun Ye
Two independent mode-locked femtosecond lasers are synchronized to an unprecedented precision. The rms timing jitter between the lasers is 4.3 fs observed within a 160 Hz bandwidth a 160 Hz bandwidth over tens of seconds, or 26 fs within a 50 kHz bandwidth

Technologies for Condition-Based Maintenance of Machine Tools

January 1, 2001
Author(s)
M A. Donmez, Kari K. Harper, Kang B. Lee
NIST has embarked upon a research effort to advance the capabilities and promote the continued growth of condition-based maintenance (CBM) technologies for the discrete-parts manufacturing industry. This research is focused on providing an alternative to

Temperature Monitoring of Capillary Rheometry Using a Fluorescence Technique

January 1, 2001
Author(s)
Anthony J. Bur, S C. Roth, H Lobo
A non-contact temperature monitoring technique based on fluorescence spectroscopy was used to measure the temperature of a polymer resin during capillary rheometry testing. Polyethylene doped with a fluorescent dye, perylene, was used in experiments that
