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

Guide to Protecting Personally Identifiable Information

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

April 27, 2010
Author(s)
Daniel T. Becker, James A. Beall, Hsiao-Mei Cho, William Duncan, Kent D. Irwin, Gene C. Hilton, Robert D. Horansky, Peter J. Lowell, Michael D. Niemack, Nicholas G. Paulter Jr., Carl D. Reintsema, Francis J. Schima, Robert E. Schwall, Ki W. Yoon, Peter Ade, Carole Tucker, Simon Dicker, Mark Halpern
We are developing a 350 GHz cryogenic passive video imaging system. This demonstration system uses 800 photon-noise-limited superconducting transition edge sensor bolometers. It will image a 1 m x 1 m area at a standoff distance of 16 m to a resolution of

Microfluidic Mixing and the Formation of Nanoscale Lipid Vesicles

April 27, 2010
Author(s)
Andreas Jahn, Samuel M. Stavis, Jennifer S. Hong, Wyatt N. Vreeland, Don L. DeVoe, Michael Gaitan
We investigate the formation of unilamellar lipid vesicles (liposomes) with diameters of tens of nanometers by microfluidic hydrodynamic focusing (MHF). Our study includes liposome synthesis experiments and numerical modeling of our microfluidic

Modifications to the NIST Reference Measurement Procedure (RMP) for the Determination of Serum Glucose by Isotope Dilution Gas Chromatography/ Mass Spectrometry

April 27, 2010
Author(s)
Jocelyn L. Prendergast, Lorna T. Sniegoski, Michael J. Welch, Karen W. Phinney
NIST has been providing a Standard Reference Material (SRM) for glucose in human serum for many years to support accuracy in health care measurements. The definitive method (DM), now known as the reference measurement procedure (RMP), for the analysis of

Report on Residential Fireground Field Experiments

April 27, 2010
Author(s)
Jason D. Averill, Lori Moore-Merrell, Adam M. Barowy, Robert Santos, Richard D. Peacock, Kathy Notarianni, Doug Wissoker
Over the past three decades, fire department response has expanded from fire prevention and fire suppression to include multiple other community services such as emergency medical services, hazardous materials response, and special rescue. Today, service

On the 60 mV/dec @300 K Limit for MOSFET Subthreshold Swing

April 26, 2010
Author(s)
Kin P. Cheung
The 60 mV/dec limit for subthreshold swing at 300K is generally considered a fundamental limit that cannot be defeated. The physical origin of this limit is revisited in this paper and the fact that this limit is in part determined by the density-ofstates
