Current-induced torques and interfacial spin-orbit coupling

December 19, 2013
Author(s)
Kyung-Jin Lee, H.-W. Lee, Aurelien Manchon, Mark D. Stiles, Paul M. Haney
In bilayer systems consisting of an ultrathin ferromagnetic layer adjacent to a metal with strong spin-orbit coupling, an applied in-plane current induces torques on the magnetization. The torques that arise from spin-orbit coupling are of particular

Dissipative production of a maximally entangled steady state of two quantum bits

December 19, 2013
Author(s)
John P. Gaebler, Yiheng Lin, Florentin Reiter, Ting Rei Tan, Ryan S. Bowler, Anders Sorensen, Dietrich G. Leibfried, David J. Wineland
Entangled states are a key resource in fundamental quantum physics, quantum cryptography, and quantum computation [1]. To date, controlled unitary interactions applied to a quantum system, so-called "quantum gates'', have been the most widely used method

Microscopic investigation of Single-Wall Carbon Nanotube Uptake by Daphnia magna

December 18, 2013
Author(s)
Aaron Edgington, Elijah Petersen, Andrew Herzing, Apparao Rao, Stephen Klaine
The objectives of this study were to determine the absorption of single-wall carbon nanotubes (SWCNTs) across the gut epithelial cells in Daphnia magna and to determine if absorption was influenced by their surface functionalization. This project utilized

Picometer Metrology for Precise Measurement of Refractive Index, Pressure, and Temperature

December 18, 2013
Author(s)
Jack A. Stone Jr., Patrick F. Egan, Donavon Gerty, Jay H. Hendricks, Douglas A. Olson, Jacob E. Ricker, Gregory E. Scace, Gregory F. Strouse
Fabry-Perot interferometers can be used for very precise measurement of the refractive index of gasses. This can enable increased accuracy of interferometer-based length measurement. In addition, because the refractive index of a gas depends on its

Review of alternative cooling technologies

December 18, 2013
Author(s)
S J. Brown, Piotr A. Domanski
This paper considers the alternative cooling technologies studied by Fisher et al. (1994) and assesses their current performance and market potential in reference to vapor compression technology. First, a taxonomy of cooling technologies based on the main

The National Vulnerability Database (NVD): Overview

December 18, 2013
Author(s)
Harold Booth, Doug Rike, Gregory A. Witte
The National Vulnerability Database (NVD), and its companion, the National Checklist Program (NCP), have provided a valuable and flexible set of services to users around the world since NVD was established in 2005. The NVD was established to provide a U.S

Does Your SEM Really Tell the Truth? - How would you know? Part 1

December 16, 2013
Author(s)
Michael T. Postek, Andras Vladar
The scanning electron microscope (SEM) has gone through a tremendous evolution to become a critical tool for many and diverse scientific and industrial applications. The high resolution of the SEM is especially suited for both qualitative and quantitative

Ionic Liquids Database - ILThermo (v2.0)

December 16, 2013
Author(s)
Andrei F. Kazakov, Joe W. Magee, Robert D. Chirico, Vladimir Diky, Kenneth G. Kroenlein, Chris D. Muzny, Michael D. Frenkel
ILThermo is a web-based ionic liquids database available free to the public. It aims to provide users worldwide with up-to-date information on publications of experimental investigation on ionic liquids, including numerical values of chemical and physical

Novel structural features in Candida albicans hyphal glucan provide a basis for differential innate immune recognition of hyphae versus yeast

December 16, 2013
Author(s)
Dan Bearden, Douglas W. Lowman, Rachel R. Greene, Michael D. Kruppa, Max Pottier, Mario Monteiro, David L. Williams
The innate immune system differentially recognizes Candida albicans yeast and hyphae. It is not clear how the innate immune system effectively discriminates between yeast and hyphal forms of C. albicans. Glucans are major components of the fungal cell wall

Mapping Trends in the Reorientational Mobilities of Tetrahydroborate Anions via Neutron-Scattering Fixed-Window Scans

December 15, 2013
Author(s)
Terrence J. Udovic, Kristina Verdal, John J. Rush, Daniel De Vries, Michael R. Hartman, John J. Vajo, Adam F. Gross, Alexander V. Skripov
The reorientational dynamics of BH 4 anions in a variety of environments of environments were measured as a function of temperature via fixed-window scans (FWSs) at zero energy transfer using a neutron backscattering spectrometer. The temperature

Mesoscale Inhomogeneities in Aqueous Solutions of Small Amphiphilic Molecules

December 15, 2013
Author(s)
Deepa Subramanian, Christopher T. Boughter, Jeffrey B. Klauda, Boualem Hammouda, Mikhail A. Anisimov
Small amphiphilic molecules, also known as hydrotropes, are too small to form equilibrium mesostructures, such as micelles, in aqueous solutions. However, aqueous solutions of nonionic hydrotropes may show the presence of a dynamic, loose, non-covalent
