March 1, 2003
Author(s)
S N. Kozlov, Vladimir L. Orkin, Robert E. Huie, Michael J. Kurylo III
The rate constants for the reactions of OH radicals with the 1-bromopropane, 2-bromopropane, and propane were measured using the flash photolysis reasonance fluorescence technique over the temperature range between 210 K and 480 K. Arrhenius plots exhibit

Optical Measurements of Structure and Orientation in Sheared Carbon-Nanotube Suspensions

March 1, 2003
Author(s)
Erik K. Hobbie, Haonan Wang, H W. Kim, Charles C. Han, E A. Grulke, Jan Obrzut
We describe an optical metrology for measuring shear-induced structure and orientation in dilute dispersions of multiwalled carbon nanotubes. Small-angle polarized light scattering and optical microscopy are combined in situ to quantify the structural

Our Plan for a Wireless Loan Service

March 1, 2003
Author(s)
Nancy Allmang
The article would describe, from a librarian's standpoint, what one library has done to gear up for a wireless LAN. It would discuss specific steps the library has taken to get a Wireless Equipment Loan Service up and running.It would explain a dual

Progress in the Development of a Kinetic Database for Heptane Combustion

March 1, 2003
Author(s)
Wing Tsang
This paper deals with the development of a chemical kinetic database for use in the simulation of heptane combustion. The database consists of the thermodynamic properties of all reactants, intermediates and products and the consequences, in terms of rate

Protein Dynamics in Viscous Solvents

March 1, 2003
Author(s)
G Caliskan, A Kisliuk, A M. Tsai, Christopher Soles, Alexei Sokolov
The principals governing the effective stabilization of tissues and drugs are unclear and effective agents for preservation are discovered largely by trail and error. We explore the use of low frequency Raman spectroscopy as an effective tool fro direct

R&D Investment Trends: U.S. Needs More High-Tech

March 1, 2003
Author(s)
Gregory C. Tassey
A varied set of barriers inhibit approaching some optimum for R&D investment. Among them is the fact that the majority of R&D is still performed in the manufacturing sector, which continues to shrink as a portion of GDP. R&D Performance within the U.S

Response of Portable Particulate Monitoring Instruments to Combustion Particulates, Road Dust, and Salt Aerosols. Volume 2 (NIST SP 995)

March 1, 2003
Author(s)
Nelson P. Bryner, William D. Walton, Laurean A. DeLauter, W H. Twilley, J. V. Mullin
This study examined the response of several particulate monitoring instruments to aerosols which might be encountered during monitoring of an in situ oil spill burn. Aerosols included road dust, salt, and particulates from the combustion of heptane, diesel

Ru Spacer Thickness Dependences of the Domain Nucleation and Growth in Co/Ru/Co Synthetic Antiferromagnet

March 1, 2003
Author(s)
V S. Gornakov, Valerian I. Nikitenko, William F. Egelhoff Jr., Robert D. McMichael, Alexander J. Shapiro, Robert D. Shull
The relative orientation of Co magnetization vectors in a Co/Ru/Co/Ta structure vary gradually from parallel to antiparallel orientation as a function of Ru thickness varying from 0 nm to 1.0 nm. At intermediate average Ru thicknesses from 0.2 nm to 0.35

March 1, 2003
Author(s)
William D. Walton, W H. Twilley, Nelson P. Bryner, Laurean A. DeLauter, R. R. Hiltabrand, J. V. Mullin
A second series of fire tests utilizing the ASTM F-20 draft, Standard Guide for In Situ Burning of Oil Spills On Water: Fire-Resistant Containment Boom, as a guideline were conducted in a wave tank at the U.S. Coast Guard Fire and Safety Test Detachment in

Self-Adaptive Leasing for Jini

March 1, 2003
Author(s)
K Bowers, Kevin L. Mills, Scott W. Rose
Distributed computing environments require strategies by which components can detect and recover from failures in remote, collaborating components. Many protocols for distributed systems employ a strategy based on leases, which grant a leaseholder with

Sharing a Common Sense of Time

March 1, 2003
Author(s)
J C. Eidson, Kang B. Lee
Distributed measurement and control systems in which all components share a common sense of time allow significant decoupling of synchronization issues from considerations of communication latency and fluctuation. This decoupling enables new techniques for

Shear-Induced Structure in Polymer Blends With Viscoelastic Asymmetry

March 1, 2003
Author(s)
Erik K. Hobbie, H Jeon, Haonan Wang, H W. Kim, D J. Stout, Charles C. Han
Light scattering and optical microscopy have been used to measure the morphology as a function of shear rate and composition in polymer blends with viscoelastic asymmetry in the melt components. The blends studied are immiscible mixtures of low-vinyl
