Measuring the effects of low energy ion milling on the magnetization of Co/Pd multilayers using scanning electron microscopy with polarization analysis

April 30, 2010
Author(s)
Benjamin James McMorran, Aaron C. Cochran, Randy K. Dumas, Kai Liu, Paul Morrow, Daniel T. Pierce, John Unguris
The dependence of the magnetic properties of Co/Pd multilayer films with very thin individual layers, Co(0.4nm)/Pd(0.6nm), on the energy of ion milling is investigated using scanning electron microscopy with polarization analysis (SEMPA). The effect of Ar

Metrology of Molecular Devices made by Flip Chip Lamination

April 30, 2010
Author(s)
Christina A. Hacker, Mariona Coll Bau, Curt A. Richter
Scaling of conventional electronics has continued unabated to dimensions approaching fundamental physical limits. As technology continues to evolve there are increasing demands to identify alternate routes of performing electrical functions. One potential

Resonance Strength in 22Ne(p,gamma)23Na from Depth Profiling in Aluminum

April 30, 2010
Author(s)
R Longland, C. Iliadis, J. Cesaratto, A E. Champagne, S Daigle, J.R. Newton, Ryan P. Fitzgerald
The novel method for extracting absolute resonance strengths has been investigated. By implanting 22Ne ions into a thick aluminum backing, and simultaneously measuring the 22Ne + p and 27Al+p reactions, the strength of the Elab,r = 479 keV resonance in

TRECVID 2009 -- Goals, Tasks, Data, Evaluation Mechanisms and Metrics

April 30, 2010
Author(s)
Paul D. Over, George M. Awad, Jonathan G. Fiscus, Martial Michel, Alan Smeaton, Wessel Kraaij
The TREC Video Retrieval Evaluation (TRECVID) 2009 was a TREC-style video analysis and retrieval evaluation, the goal of which was to promote progress in content-based exploitation of digital video via open, metrics-based evaluation. 63 teams from various

Feshbach resonances in ultracold gases

April 29, 2010
Author(s)
Chin P. Cheng, R Grimm, Paul S. Julienne, Eite Tiesinga
Feshbach resonances are the essential tool to control the interaction between atoms in ultracold quantum gases. They have found manifold experimental applications, opening up the way to important breakthroughs. This Review gives a broad coverage of the

Microfluidic Directed Self-Assembly of Liposome-Hydrogel Hybrid Nanoparticles

April 29, 2010
Author(s)
Jennifer S. Hong, Samuel M. Stavis, Silvia H. De Paoli Lacerda, Laurie E. Locascio, Srinivasa R. Raghavan, Michael Gaitan
We present a microfluidic method to direct the self-assembly of liposome-hydrogel hybrid nanoparticles. Our approach yields nanoparticle size distributions that are highly monodisperse and precisely controlled across a broad range relevant to the targeted

RFSQUID-Mediated Coherent Tunable Coupling Between a Superconducting Phase Qubit and a Lumped Element Resonator

April 29, 2010
Author(s)
Michael S. Allman, Fabio Altomare, Jed D. Whittaker, Katarina Cicak, Dale Li, Adam J. Sirois, Joshua Strong, John D. Teufel, Raymond W. Simmonds
We demonstrate coherent tunable coupling between a superconducting phase qubit and a lumpedelement resonator. The coupling strength is mediated by a flux-biased rf SQUID operated in the nonhysteretic regime. By tuning the applied flux bias to the rf SQUID

An LC-ESI/MS Method for Determining Theanine in Green Tea Dietary Supplements

April 28, 2010
Author(s)
Mary Bedner, Lane C. Sander, Katherine E. Sharpless
Theanine is the major amino acid present in Camellia sinensis, or green tea. A method for determining theanine in its native state using liquid chromatography with positive-mode electrospray ionization mass spectrometric detection was developed

April 28, 2010
Author(s)
Shirley M. Radack
This bulletin summarizes the information presented in NIST Special Publication (SP) 800-122, Guide to Protecting the Confidentiality of Personally Identifiable Information (PII). Written by Erika McCallister, Tim Grance, and Karen Scarfone of NIST, the

MgO Tunnel Barriers in Magnetic Nanostructures and Devices

April 28, 2010
Author(s)
Ranko R. Heindl, Matthew Pufall, William Rippard
In recent years, there has been a great deal of success in the development of MgO based tunnel barriers for use in magnetic devices, such as nanoscale magnetic random access memory elements (MRAM) and magnetic field sensors. Much of the focus has been on

A 350-GHz high-resolution high-sensitivity passive video imaging system
