Interfacial Exchange Coupling in Fe/(Ga,Mn)As Bilayers

June 16, 2014
Author(s)
A. M. Alsmadi, Y. Choi, D.J. Keavney, K.F. Eid, Brian Kirby, X. Liu, J. Leiner, K. Tivakornsasithorn, M. Dobrowolska, J. K. Furdyna
We have carried out a systematical study of magnetic order and magnetic interlayer coupling in Fe/(Ga,Mn)As bilayers using superconducting quantum interference device magnetometry, polarized neutron reflectometry, element-specific x-ray absorption

Just Add Water reproducible singly dispersed silver nanoparticle suspensions

June 19, 2013
Author(s)
Robert I. MacCuspie, Andrew J. Allen, Matthew N. Martin, Vincent A. Hackley
Silver nanoparticles (AgNPs) are of interest due to their antimicrobial attributes, which are derived from their inherent instability and subsequent release of silver ions into solution. At the same time, this instability makes achieving stable long-term

Ultracold Atoms and Precise Time Standards

September 19, 2011
Author(s)
Gretchen K. Campbell, William D. Phillips
Experimental techniques of laser cooling and trapping, along with other cooling techniques have produced gaseous samples of atoms so cold that they are, for many practical purposes, in the quantum ground state of their center-of-mass motion. Such low

Potassium Induced Charge Transfer Effects in OPE-based Molecular Layers

August 11, 2011
Author(s)
Steven W. Robey, Gregory J. Dutton
The impact of potassium (K) addition on the electronic structure of oligo- (phenylene ethynylene) (OPE) and –NO2 substituted OPE (NO2-OPE) self-assembled monolayers was examined using ultraviolet photoemission. Addition below 0.5 K/molecule produced rigid

NIST 40. NDRL/NIST Solution Kinetics Database: Version 3.0

October 16, 2008
Author(s)
J R. Rumble
The NDRL/NIST Solution Kinetics Database includes chemical kinetic data for free radical processes involving primary radicals from water, inorganic radicals (including transients from metal ions and metal complexes) and carbon-centered radicals in solution

Ionic Liquids Database (ILThermo)

July 23, 2006
Author(s)
Qian Dong, Andrei F. Kazakov, Chris D. Muzny, Robert D. Chirico, Jason A. Widegren, Vladimir Diky, Joe W. Magee, Kenneth N. Marsh, Michael D. Frenkel
Ionic Liquids Database (ILThermo)is a free web research tool that allow users worldwide to access an up-to-data data collection from the publications on experimental studies of thermodynamic and transport properties of ionic liquids, as well as binary and

Formation of aluminum oxide thin films on FeAl(110) studied by STM

February 6, 2003
Author(s)
Orhan Kizilkaya, Dustin Hite, David M. Zehner, Phillip T. Sprunger
The surface morphology and atomic structure of clean and oxidized FeAl(l 10) surfaces have been investigated with scanning tunneling microscopy (STM). An incommensurate reconstructed structure, having FeAl2 stoichiometry confined to the outmost layer, is

DNA Mass Spectrometry at NIST

Author(s)
Peter M. Vallone
… laboratory is a MALDI-TOF device equipped with a gridless ion reflector detector for improved mass resolution. A second …

Electron Interactions with c-C 4 F 8

January 1, 2001
Author(s)
Loucas G. Christophorou, James K. Olthoff
… and scattering suggests the existence of negative ion states at about - 0.6 eV, 4.9 eV, 6.9 eV, 9.0 eV, and …

Concrete: A Multi-Scale Interactive Composite

March 1, 1998
Author(s)
Edward J. Garboczi, Dale P. Bentz
Methods have been developed for predicting the overall diffusion coefficient of ions in concrete using a multi-scale interactive analysis, ignoring any chloride binding interactions. The analysis makes use of microstructure models of mortar/concrete and
