Development of a Tunable LED-Based Colorimetric Source

Author(s)
Steven W. Brown, C Santana, George P. Eppeldauer
A novel, spectrally tunable light-source utilizing light emitting diodes (LED's) for radiometric, photometric, and colorimetric applications is described. The

Diffractive Optics From Self-Assembled DNA

Author(s)
Zachary H. Levine
An algorithm is presented for assembling tiles into a variable spaced grating, the one-dimensional analogue of Fresnel zone plate. The algorithm supports

Photoassociation in a Bose-Einstein Condensate

Author(s)
Paul D. Lett
Two colliding atoms can absorb a photon and be photoassociated into an excited, diatomic molecule, NIST researchers investigated the fundamental rate at which

Test Procedures for Developing Solder Data

Author(s)
Thomas A. Siewert, C A. Handwerker
This publication documents standardized test procedures that can produce valid and reproducible mechanical property data for lead-free solders. Such data speeds

Metal Detector Studies: Research Materials

Author(s)
James R. Baker-Jarvis, Raian K. Kaiser, Michael D. Janezic, Nicholas Paulter, Ken L. Stricklett
The purpose of the work described in this report is to develop and characterize materials that mimic the electromagnetic characteristics of the human body. The

Community-Scale Fire Spread

Author(s)
Ronald G. Rehm, Anthony P. Hamins, Howard R. Baum, Kevin B. McGrattan, D D. Evans
This paper addresses community-scale fires, which have also been called urban/wildland interface or intermix fires. These fires arise when wildlandfires invade

Fire Safety Research at NIST

Author(s)
Anthony P. Hamins
The Fire Research Division is one of four Divisions in the Building and Fire Research Laboratory (BFRL) at the National Institute of Standards and Technology

Planning with Incrementally Created Graphs

Author(s)
Stephen B. Balakirsky, Otto H. Herzog
A framework for planning algorithms that is both optimal and complete will be presented that allows for the planning of optimal paths through a multi-level

Gas-Phase Mechanisms of Fire Retardants

Author(s)
Gregory T. Linteris
Fire retardants are added to polymers to increase their ignition time and reduce their heat release rates when burning. They are often described as acting
