Black phosphorus tunneling field-effect transistors

December 21, 2018
Author(s)
Albert Davydov, Huairuo Zhang, Leonid A. Bendersky
Band-to-band tunneling field-effect transistors (TFETs)1-7 have emerged as promising candidates to replace conventional metal-oxide-semiconductor field-effect transistors (MOSFETs) for low-power integration circuits and have been demonstrated to overcome

Generating Domain Terminologies using Root- and Rule-Based Terms

December 21, 2018
Author(s)
Talapady N. Bhat, John T. Elliott, Ursula R. Kattner, Carelyn E. Campbell, Eswaran Subrahmanian, Ram D. Sriram, Jacob Collard, Monarch Ira
Motivated by the need for exible, intuitive, reusable, and normalized ter- minology for the semantic web, we present a general approach for generat- ing sets of such terminologies from nat- ural language documents. The terms that this approach generates

Hidden Hyperuniformity in Bottlebrush Polymer Melts

December 21, 2018
Author(s)
Alexandros Chremos, Jack F. Douglas
We show that the backbone chains of bottlebrush polymer melts exhibit a hidden hyperuniform packing over a wide temperature range above glass transition temperature. These findings open a venue for a practical design of hyperuniform polymeric materials for

Performance-based design to achieve community resilience

December 21, 2018
Author(s)
Bruce Ellingwood, Naiyu Wang, James Harris, Therese P. McAllister
The resilience of communities depends on the performance of the built environment and on supporting social, economic and public institutions on which the welfare of the community depends. The built environment is susceptible to damage due to a spectrum of

Phonon Localization in Heat Conduction

December 21, 2018
Author(s)
M. N. Luckyanova, J. Mendoza, H. Lu, B. Song, S. Huang, J. Zhou, M. Li., Y. Dong, H. Zhou, J. Garlow, L. Wu, Brian Kirby, Alexander Grutter, Alex A. Puretzky, Y. Zhu, M. S. Dresselhaus, A. Gossard, G. Chen
We report localization-like behavior in phonon heat conduction observed both in measurement of the thermal conductivities of GaAs/AlAs superlattice (SL) thin films with interfacial disorder caused by ErAs nanodots randomly distributed at the interfaces

Spin Waves Across Three-Dimensional, Close-Packed Nanoparticles

December 21, 2018
Author(s)
Kathryn Krycka, James Jennings Rhyne, Samuel D Oberdick, Ahmed M. Abdelgawad, Julie A. Borchers, Yumi Ijiri, Sara A. Majetich, Jeffrey W. Lynn
Inelastic neutron scattering is utilized to measure the spin waves, or magnons, which arise from inter-particle coupling between 8.4 nm ferrite nanoparticles that are self-assembled into a close-packed lattice, yet physically separated by oleic acid

Threat Modeling for Cloud Infrastructures

December 21, 2018
Author(s)
Nawaf Alhebaishi, Lingyu Wang, Anoop Singhal
Today's businesses are increasingly relying on the cloud as an alternative IT solution due to its flexibility and lower cost. Compared to traditional enterprise networks, a cloud infrastructure is typically much larger and more complex. Understanding the

A Study of Capsule Endoscopy Orientation Estimation Using Received Signal Strength

December 20, 2018
Author(s)
Kamran Sayrafian, Katjana Krhac, Mehdi Alasti, Kamya Yazdandoost, Dina Simunic
Comprehensive study of wireless communication for ingestible electronics is a very challenging task. To initiate the study on wireless capsule endoscopy, an innovative immersive platform containing an enhanced 3D human body model has been developed. This

Evaluation of Nanoscale Accessible Pore Structures for Improved Prediction of Gas Production Potential in Chinese Marine Shales

December 20, 2018
Author(s)
Yang Wang, Yong Qin, Rui Zhang, Lilin He, Lawrence M Anovitz, Markus Bleuel, David F. Mildner, Shimin Liu, Yanming Zhu
The lower Cambrian Niutiang and Lower Silurian Longmaxi shales in the Upper Yangtze Platform (UYP) are considered as the most promising strata for shale gas exploration in China. To shed light on the study of evaluation of nanoscale pore structure for

Identification of dopant site and its effect on electrochemical activity in Mn-doped Lithium Titanate

December 20, 2018
Author(s)
Harischchandra Singh, Mehmet Topsakal, Klaus Attenkofer, Tamar Wolf, Michal Leskes, Yandong Duan, Feng Wang, John Vinson, Deyu Lu, Anatoly Frenkel
We observed significant battery rate performance drop of nearly 20% in 1% Mn doped Lithium Titanate (LTO) compared to the pristine LTO. Using a combination of the X-ray absorption near edge structure experiment with theoretical modeling we demonstrated

Impact of Measurement Points Distribution on the Parameters of UWB Implant Channel Model

December 20, 2018
Author(s)
Kamran Sayrafian, Sofia Perez-Simbor, Katjana Krhac, Concepcion GarciaPardo, Dina Simunic, Narcis Cardona
Sophisticated medical implants that allow vital information delivery to/from the human body are opening the door to novel approaches in diagnosis and/or therapy of various health related issues. Ultra-Wide Band (UWB) technology is gaining the attention of

Measurement Science Roadmap Workshop for Water Use Efficiency and Water Quality in Premise Plumbing Systems, August 1-2, 2018: Synthesis of a Workshop organized by the National Institute of Standards and Technology, U.S. Environmental Protection Agency, a

December 20, 2018
Author(s)
Robert Pickering, Kathleen Onorevole, Rob Greenwood, Sarah Shadid
In August 2018, the National Institute of Standards and Technology (NIST), the U.S. Environmental Protection Agency (EPA) WaterSense program, and the Water Research Foundation (WRF) organized a Measurement Science Roadmap Workshop for Water Use Efficiency

The Metrological Basis for MOBY

December 20, 2018
Author(s)
Bettye C. Johnson
The Marine Optical BuoY (MOBY) is a primary source of data for System Vicarious Calibration (SVC) of ocean color satellite sensors. I will present brief introduction to SVC followed by a short history of MOBY and the main features of its instrumentation

Thermodynamic assessment of the Co-Ta system

December 20, 2018
Author(s)
Peisheng Wang, J?rg Ko?mann, Ursula R. Kattner, Mauro Palumbo, Thomas Hammerschmidt, Gregory B. Olson
The Co-Ta system has been reviewed and the thermodynamic description was re-assessed in the present work. DFT (density functional theory) calculations considering spin polarization were performed to obtain the energies for all end-member configurations of
