Morphological and Electrical Characterization of MWCNT Papers and Pellets

December 27, 2015
Author(s)
Elisabeth Mansfield, Ari D. Feldman, Ann C. Chiaramonti Debay, John H. Lehman, Alexandra E. Curtin
Six types of multiwall carbon nanotube soot were obtained and prepared into buckypapers by pellet pressing and by filtration into a paper. These samples were evaluated with respect to thickness, compressibility and electrical conductivity. DC conductivity

Chapter 5: Multiferroics

December 24, 2015
Author(s)
William D. Ratcliff, Jeffrey W. Lynn
Multiferroics are insulating materials that are simultaneously magnetically ordered and ferroelectric. From a fundamental standpoint it is interesting to understand the properties and coupling of these two disparate types of order. These materials could

UV-assisted room-temperature chemiresistive NO2 sensor based on TiO2 thin film

December 24, 2015
Author(s)
Ting Xie, Nichole Sullivan, Kristen L. Steffens, Baomei Wen, Guannan Liu, Ratan K. Debnath, Albert Davydov, Romel D. Gomez, Abhishek Motayed
TiO2 thin film based, chemiresistive sensors for NO2 gas which operate at room temperature under ultraviolet (UV) illumination have been demonstrated in this work. The rf-sputter deposited and post-annealed TiO2 thin films have been characterized by atomic

Nucleobase-functionalized graphene nanoribbons for accurate high-speed DNA sequencing

December 23, 2015
Author(s)
Eugene Paulechka, Tsjerk A. Wassenaar, Kenneth Kroenlein, Andrei Kazakov, Alexander Smolyanitsky
We propose a water-immersed nucleobase-functionalized suspended graphene nanoribbon as an intrinsically selective device for nucleotide detection. The proposed sensing method combines Watson–Crick selective base pairing with graphene's capacity for

Tip characterization method using multi-feature characterizer for CD-AFM

December 23, 2015
Author(s)
Ndubuisi Orji, Hiroshi Itoh, Chumei Wang, Ronald G. Dixson, Sebastian Schmidt, Bernd Irmer, Peter S. Walecki
In atomic force microscopy (AFM) metrology, the tip is a key source of uncertainty. Images taken with an AFM show a change in feature width and shape that depends on tip geometry. This geometric distortion is more pronounced when measuring features with

Analysis and Optimization based on Reusable Knowledge Base of Process Performance Models

December 22, 2015
Author(s)
Alexander Brodsky, Guodong Shao, Mohan Krishnamoorthy, Anantha Narayanan Narayanan, Daniel Menasc?, Ronay Ak
In this paper, we propose an architectural design and software framework for fast development of descriptive, diagnostic, predictive, and prescriptive analytics solutions for dynamic production processes. The proposed architecture and framework will

Cloud-based Accessibility for Voting Applications

December 22, 2015
Author(s)
Shanee T. Dawkins, Sharon J. Laskowski
Since its creation, the National Institute on Disability and Rehabilitation Research (NIDRR) of the U.S. Department of Education (ED) has supported the development of new technologies for enhancing access for people with disabilities. Current research and

High-efficiency superconducting nanowire single-photon detectors fabricated from MoSi thin-films

December 22, 2015
Author(s)
Varun B. Verma, Boris Korzh, Felix Bussieres, Robert D. Horansky, Shellee D. Dyer, Adriana E. Lita, Igor Vayshenker, Francesco Marsili, Matthew D. Shaw, Hugo Zbinden, Richard P. Mirin, Sae Woo Nam
We report on MoSi SNSPDs which achieved high system detection efficiency (87.1 ± 0.5% at 1542 nm) at 0.7 K and we demonstrate that these detectors can also be operated with saturated internal efficiency at a temperature of 2.3 K in a Gifford-McMahon

Methods and Tools for Performance Assurance of Smart Manufacturing Systems

December 22, 2015
Author(s)
Deogratias Kibira, Katherine C. Morris, Senthilkumaran Kumaraguru
The emerging concept of smart manufacturing systems is defined in part by the introduction of new technologies that are promoting rapid and widespread information flow within the manufacturing system and surrounding its control. These systems can deliver

Scattering Studies on Poly(3,4-ethylenedioxythiophene) Polystyrenesulfonate in the Presence of Ionic Liquids

December 22, 2015
Author(s)
Ryan J. Murphy, Kathleen Weigandt, David Uhrig, Ahmed Alsayed, Chantal Badre, Larry Hough, Murugappan Muthukumar
The demand for lower-cost and flexible electronics has driven industry to develop alternative transport electrode (TE) materials to replace Indium Tin Oxide (ITO). ITO is the benchmark TE on the market, but its high cost and low flexibility limits it for

Intrinsic Spin Torque Without Spin-Orbit Coupling

December 21, 2015
Author(s)
Kyoung-Whan Kim, Kyung-Jin Lee, Hyun-Woo Lee, Mark D. Stiles
For non-uniform magnetic textures, we derive an intrinsic contribution to the non-adiabatic spin torque that may be the dominant contribution. It differs from previously considered contributions in several ways. It does not depend on the change in

Managing Risk in a Cloud Ecosystem

December 18, 2015
Author(s)
Michaela Iorga, Anil Karmel
The article focuses on the tier 3 security risks related to the operation and use of cloud-based information systems. To prevent and mitigate any threats, adverse actions, service disruptions, attacks, or compromises, organizations need to quantify their

New perspective on glycoside hydrolase binding to lignin from pretreated corn stover

December 18, 2015
Author(s)
John M. Yarbrough, Ashutosh Mittal, Elisabeth Mansfield, Larry Taylor, Sarah Hobdey, Deanne W. Sammond, Yannick J. Bomble, Michael F. Crowley, Stephen R. Decker, Michael E. Himmel, Todd B. Vinzant
Non-specific binding of cellulases to lignin has been implicated as a major factor in the loss of cellulase activity during biomass conversion to sugars. It is believed that this binding may strongly impact process economics through loss of enzyme

Polarity-Controlled GaN/AlN Nucleation Layers for Selective-Area Growth of GaN Nanowire Arrays on Si(111) Substrates by Molecular Beam Epitaxy

December 18, 2015
Author(s)
Matthew D. Brubaker, Shannon M. Duff, Todd E. Harvey, Paul T. Blanchard, Alexana Roshko, Aric W. Sanders, Norman A. Sanford, Kristine A. Bertness
We have demonstrated dramatic improvement in the quality of selective-area GaN nanowire growth by controlling the polarity of the underlying nucleation layers. In particular, we find that N- polarity is beneficial for the growth of large ordered nanowire

Third-Party Software's Trust Quagmire

December 18, 2015
Author(s)
Jeffrey M. Voas, George Hurlburt
Integrating software developed by third-party organizations into a larger system raises concerns about the software's quality, origin, functionality, security, and interoperability. Addressing these concerns requires rethinking the roles of software's
