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

Measuring a Device's Susceptibility to LTE: Preliminary Approaches

March 15, 2015
Author(s)
Jason B. Coder, John M. Ladbury
Previous testing has shown that measuring a device’s susceptibility to a radiated, broadband signal can present a different set of challenges than those faced when testing with a narrow-band signal. Decisions ranging from choosing a measurement facility to

Nationwide Public Safety Broadband Network Deployment: Network Parameter Sensitivity Analysis

March 15, 2015
Author(s)
Richard A. Rouil, Antonio Izquierdo Manzanares, Camillo A. Gentile, David W. Griffith, Nada T. Golmie
The legislation included in the middle class tax relief and job creation act of 2012 established the First Responder Network Authority (FirstNet) for the purpose of deploying and running a nationwide Long Term Evolution (LTE) network for Public Safety

System Vicarious Calibration for Ocean Color Climate Change Applications: Requirements for In Situ Data

March 15, 2015
Author(s)
Giuseppe Zibordi, Frederic Melin, Kenneth Voss, B. Carol Johnson, Bryan Franz, Ewa Kwiatkowska, J. P. Huot, Menghua Wang, David Antoine
System Vicarious Calibration (SVC) ensures a relative radiometric calibration to satellite ocean color sensors that minimizes uncertainties in the water-leaving radiance Lw derived from the top of atmosphere radiance LT. This is achieved through the
