Author(s)
XiaoJuan Feng, Keith A. Gillis, Michael R. Moldover, James B. Mehl
We measured 5 microwave resonance frequencies f N of an argon-filled cylindrical cavity at temperatures up to 1349 K. The repeatability of both the measured frequencies u(f N) and the scaled half-widths u(g N)/ f N was better than 10 -6f N. The measurement

Size tolerancing revisited: A basic notion and its evolution in standards

May 13, 2013
Author(s)
Vijay Srinivasan, Edward P. Morse
Size is a fundamental descriptor of objects – it allows us to quantify 'how big' objects are, and to compare and classify objects based on this notion. In the world of ISO GPS (Geometrical Product Specification and Verification), size is defined much more

Tools and Approaches for the Assessment of Nanomaterial Induced Oxidative DNA Damage

May 13, 2013
Author(s)
Elijah J. Petersen, Bryce Marquis, Pawel Jaruga, M Miral Dizdar, Bryant C. Nelson
Hyphenated mass spectrometry techniques have been employed as one of the primary analytical tools for investigating the effects of ionizing radiation, chemical/biological carcinogens, and oxygen derived free radicals on the induction and subsequent repair

Author(s)
Samuel L. Manzello, Tokiyoshi Yamada, Ann Jeffers, Yoshifumi Ohmiya, Keisuke Himoto, A C. Fernandez-Pello
A workshop, known as “Operation Tomodachi – Fire Research” was held in Tokyo, Japan from July 1 to July 4, 2012. Tomodachi means friendship in Japanese. This workshop, under the direction of Dr. Samuel L. Manzello of EL-NIST and Dr. Tokiyoshi Yamada of the

Metrology for Lab-on-a-Chip Final-Product Devices

May 12, 2013
Author(s)
Darwin R. Reyes-Hernandez, Michael W. Halter, Jeeseong Hwang
New metrology tools to measure the critical parameters of internal structures in lab on a chip devices are greatly needed in order to develop standard tests for this technology. Here we present a method that combines a custom made optical coherence
