High-Fidelity, Weak-Light Polarization Gate Using Room-Temperature Atomic Vapor

March 18, 2015
Author(s)
Lu Deng, Edward W. Hagley, Runbing Li, Chengjie Zhu
Using a polarization-selective-Kerr-phase-shift technique we demonstrate a fast, all-optical, high-fidelity polarization gate in a room-temperature atomic medium. By writing a pi-phase shift to one selected circularly-polarized component of a linearly

Light-wave mixing and scattering with quantum gases

March 18, 2015
Author(s)
Lu Deng, Edward W. Hagley, C.J. Zhu
We show that optical processes originating from elementary excitations with dominant collective atomic recoil motion in a quantum gas can profoundly change many nonlinear optical processes routinely observed in a normal gas. Not only multi-photon wave

Preparation and Separation of DNA-Wrapped Carbon Nanotubes

March 18, 2015
Author(s)
Geyou Ao, Ming Zheng
Purification of single-chirality single-wall carbon nanotubes (SWCNTs)from their synthetic mixture is a prerequisite for many applications. DNA-controlled carbon nanotube (CNT) purification has evolved over a decade along with other separation techniques

Redox sorting of carbon nanotubes

March 17, 2015
Author(s)
Hui Gui, Jason K. Streit, Jeffrey Fagan, Angela R. Hight Walker, Chongwu Zhou, Ming Zheng
This work expands the redox chemistry of single-wall carbon nanotube (SWCNT) by investigating its role in a number of SWCNT sorting processes. Using a polyethylene glycol (PEG)/dextran (DX) aqueous two-phase system, we show that electron-transfer reaction

The Multiplicative Complexity of Boolean Functions on Four and Five Variables

March 17, 2015
Author(s)
Meltem Sonmez Turan, Rene C. Peralta
A generic way to design lightweight cryptographic primitives is to construct simple rounds using small nonlinear components such as 4x4 S-boxes and use these iteratively (e.g., PRESENT and SPONGENT). In order to efficiently implement the primitive, optimal

X-ray CT imaging and finite element computations of the elastic properties of a rigid organic foam compared to experimental measurements: Implications for foam grade differences and process control

March 17, 2015
Author(s)
Edward Garboczi, Aaron Forster, Jan Miller, Chen-Luh Lin, Cesar Chan, Kumar Natesaiyer, David Song, Suman Sinha-Ray
A combined computational/experimental materials science technique was developed for acquiring the structure of a rigid organic foam (ROHACELL) using X-ray computed tomography with appropriate image analysis, computing the elastic moduli using large-scale

Beam broadening in transmission EBSD

March 16, 2015
Author(s)
Robert R. Keller, Katherine P. Rice, Mark Stoykovich
Transmission electron backscatter diffraction (t-EBSD), also known as transmission electron forward scatter diffraction (t-EFSD) or transmission Kikuchi diffraction in the SEM (TKD-SEM), can provide significant improvements in spatial resolution over

Development and evaluation of interface-stabilized and reactive-sputtered oxide-capped multilayers for EUV lithography

March 16, 2015
Author(s)
Michael Kriese, Jim Rodriguez, Gary Fournier, Steven Grantham, Shannon B. Hill, John J. Curry, Charles Tarrio, Yuriy Platonov
A critical component of high-performance EUV lithography source optics is the reflecting multilayer coating. The ideal multilayer will have both high reflectance and high stability to thermal load. Additionally the capping layers must provide resistance to

Dynamic Stress Analysis Applied to the Electrodeposition of Copper

March 16, 2015
Author(s)
Manon C. Lafouresse, Ugo Bertocci, Gery R. Stafford
Stress development during the electrodeposition of copper from additive-free, acidic CuSO_(4) electrolyte was analyzed by dynamic stress analysis, an in situ characterization technique that combines electrochemical impedance spectroscopy with cantilever

A Review of Wireless Coexistence Test Methodologies

March 15, 2015
Author(s)
William F. Young, Jason B. Coder, Luis A. Gonzalez
This paper discusses several wireless coexistence test methods in-practice and proposed for industry standards such as ANSI C63.27 The test methods include conducted and radiated setups, and utilize a range of technologies at various levels of
