Thermal Decomposition of RP-2 with Stabilizing Additives

May 7, 2010
Author(s)
Jason A. Widegren, Thomas J. Bruno
The thermal decomposition of RP-2 and mixtures of RP-2 with four different additives has been investigated. The mixtures with RP-2 contained one of the following: 5 % /trans/-decahydronaphthalene (decalin); 5 % 1,2,3,4-tetrahydronaphthalene (tetralin); 5 %

Strategies for Concordance Testing

May 1, 2010
Author(s)
Carolyn R. Steffen, David L. Duewer, Margaret C. Kline, John M. Butler
Concordance evaluations are important to conduct to determine if there are any allelic dropout or “null alleles” present in a data set. These studies are based on the fact that there are a variety of commercial short tandem repeat (STR) multiplex kits

CCQMK62: Nutrients in Infant/Adult Formula Vitamins: Final Report

April 24, 2010
Author(s)
Katherine E. Sharpless, Catherine A. Rimmer, Karen W. Phinney, Bryant C. Nelson, David L. Duewer, Stephen A. Wise
Key Comparison CCQM-K62 was designed to enable demonstration of the equivalence in capabilities for measurement of vitamins in a food matrix. A milk-based fortified human infant/adult formula was selected as the matrix based upon material availability and

Kinetics of the Thermal Reaction of H Atoms with Propyne

April 15, 2010
Author(s)
Claudette M. Rosado-Reyes, Jeffrey A. Manion, Wing Tsang
The reaction of hydrogen atoms with propyne(CH≡CCH3) has been investigated in a heated single pulse shock tube at temperatures of 870-1145K and pressures of 2-9 bar. Stable products from various reaction channels (terminal and non-terminal H addition, and

The A 2E" - X 2A2' Transition of NO 3 Trapped in Solid Neon

April 7, 2010
Author(s)
Marilyn E. Jacox, Warren E. Thompson
NO3 has been stabilized in a neon matrix at 4.3 K in sufficient yield for detection of the absorptions between 7000 and 10000 cm-1 which arise from vibronically allowed transitions from its ground state to levels of the A 2E" state. The results confirm and

Flip Chip Lamination approach to fabricate top metal contacts on organic-based devices ; M.Coll, O.D. Jurchescu, N. Gergel-Hackett, C.A. Richter, C,A, Hacker, American Physical Society (APS), March 2010, Portland, OR, USA (oral)

Fluorinated Copolymer Nanoparticles for Multimodal Imaging Applications

February 18, 2010
Author(s)
Mark M. Bailey, Christine M. Mahoney, Elodie Dempah, Jeffrey M. Davis, Matthew Becker, Supang Khondee, Eric J. Munson, Cory J. Berkland
Nanomaterials have emerged as valuable tools in biomedical imaging techniques, such as magnetic resonance imaging (MRI), fluorescence, positron emission tomography (PET), and others. Some have been designed to serve as multimodal imaging agents, combining

Rational synthesis and characterization of a new family of low thermal conductivity misfit layered compounds [(PbSe)0.99]m[(WSe2)]n

February 9, 2010
Author(s)
Ian M. Anderson, Michael D. Anderson, Qiyin Lin, Mary Smeller, Colby L. Heideman, Paul Zschack, Mikio Koyano, Robert Kykyneshi, Douglas A. Keszler, David C. Johnson
We describe here a general synthesis approach for the preparation of new families of misfit layer compounds and demonstrate its effectiveness through the preparation of the first 64 members of the [(PbSe)0.99]m(WSe2)n family of compounds, where m and n are

Ergodic Convergence Times For Molecular Liquids

January 22, 2010
Author(s)
Raymond D. Mountain
A problem common to all molecular dynamics and Monte Carlo simulations used to estimate fluid properties is how to decide when adequate sampling of the phase space of the system has been realized. One procedure for addressing the sampling question is to

Solvent Retention In Thin Spin-Coated Polystyrene And Poly(Methyl Methacrylate) Homopolymer Films Studied By Neutron Reflectometry

January 19, 2010
Author(s)
Xiaohua Zhang, Kevin G. Yager, Shuhui Kang, Nathaniel J. Fredin, Bulent Akgun, Sushil K. Satija, Jack F. Douglas, Alamgir Karim, Ronald L. Jones
We utilize neutron reflectometry (NR) to probe the amount of residual solvent inside thin polystyrene (PS) and poly(methyl methacrylate) (PMMA) films spin-coated from deuterated toluene polymer solutions onto silicon substrates . The effect of thermal

Density and Speed of Sound Measurements of Hexadecane

January 7, 2010
Author(s)
Stephanie L. Outcalt, Arno R. Laesecke, Tara J. Fortin
The density and speed of sound of hexadecane have been measured using two instruments. Both instruments use the vibrating-tube method for measuring density. Ambient pressure (83 kPa) density and speed of sound measurements were carried out with a rapid
