Flame Suppression Effectiveness of Halon Alternatives (NISTIR 5499)

September 1, 1994
Author(s)
William L. Grosshandler, Anthony P. Hamins
The elimination of new production of halon 1301 has forced the manufacturers, owners, and users of aircraft to search for an alternative. The program described here developed performance screens for candidate agents as a means to identify the best

Comparison of Strength Properties of Normotensive and Hypertensive Rat Pulmonary Arteries

October 1, 2004
Author(s)
Elizabeth S. Drexler, Christopher N. McCowan, J Wright, Andrew J. Slifka, Dunbar Ivy, Robin Shandas
A series of tests were conducted to quantify the difference in the mechanical properties of normo-and hypertensive pulmonary arteries. A bubble-test design was emplpoyed to measure the biaxial properties of a segment of artery. The test results compare the

Constitutive Models for a Poly(e-caprolactone) Scaffold

October 1, 2004
Author(s)
Timothy P. Quinn, Tammy L. Oreskovic, Christopher N. McCowan, N Washburn
We investigate material models for a porous, polymeric scaffold used for bone. The material was made by co-extruding poly (e-caprolactone) (PCL), a biodegradable polyester, and poly(ethylene oxide)(PEO). The water soluble PEO was removed resulting in a

Static and Quasi-static Calibration of Bio-MEMS Device

October 1, 2004
Author(s)
Andrew J. Slifka, Hrishikesh V. Panchawagh, Roop L. Mahajan, Dudley Finch, R. A. Rorrer
A bio-MEMS device which has been designed to stimulate cells by oscillatory actuation in the vertical direction has been calibrated. The displacement of this device was determined experimentally by a laser interferometer when actuated by a static voltage

The complete sequence of a human Y chromosome

August 23, 2023

Arang Rhie, Sergey Nurk, Monika Cechova, Savannah Hoyt, Dylan Taylor, Nathanael David Olson, Justin Zook, Adam Phillippy
… ampliconic structures of gene families TSPY, DAZ and RBMY; 41 additional protein-coding genes, mostly from the TSPY …

VECSEL systems for quantum information processing with trapped beryllium ions

March 10, 2023
Author(s)
Shaun C. Burd, Jussi-Pekka Penttinen, Panyu Hou, Hannah Knaack, Sanna Ranta, Mika Maki, Emmi Kantola, Mircea Guina, Daniel Slichter, Dietrich Leibfried, Andrew C. Wilson
… system generates 1.6 W at 1252 nm, which is converted to 41 mW of 313 nm light that is used to laser cool trapped 9Be+ …

Tunnel junction sensors for HCI-surface measurements at low kinetic energies

January 25, 2013
Author(s)
Joshua M. Pomeroy, Russell E. Lake
In recent years, we have developed and deployed the capability to make and use tunnel junctions sensors (TJS) as extremely sensitive tools for the measurement of surface nanofeatures created by particle surface interactions. Highly charged ion (HCI)

Detection of Interstellar Cyanoformaldehyde (CNCHO)

December 31, 2007
Author(s)
Francis J. Lovas, Anthony J. Remijan, Jan M. Hollis, Wilmer D. Stork, Phil R. Jewell, D Meier

Low noise thermistor read out for wideband room temperature infrared detectors

September 25, 2016
Author(s)
Ivan Ryger, Michelle S. Stephens, John H. Lehman, Matthew T. Spidell, Malcolm G. White, Nathan A. Tomlin, Dave Harber, Peter Lobotka
An absolute electrical substitution radiometer is a way to ensure highly accurate and stable measurement of optical power in a wide range of optical wavelengths. Its sensitivity is mainly determined by the temperature stability of the equithermal bath and
