Cascaded emission of single photons from the biexciton in monolayered WSe2

November 10, 2016
Author(s)
Yu-Ming He, Oliver Iff, Nils Lundt, Vasilij Baumann, Marcelo I. Davanco, Kartik Srinivasan, Sven Hofling, Christian Schneider
Monolayers of transition metal dichalcogenide materials emerged as a new material class to study excitonic effects in solid state. They benefit from the enormous coulomb correlations between electrons and holes, as a result of reduced dielectric screening

Fabrication, Testing and Simulation of All Solid State Three Dimensional Li-ion Batteries

November 10, 2016

Yaojin Wang, Ding Wang, Guoliang Yuan, He Ma, Feng Xu, Jiefang Li, D. Viehland, Peter M. Gehring
We have examined the effects of field cooling on the phase diagram of the relaxor system (1-X)Pb(Zn 1/3Nb 2/3)O6d3-x^PbTiO 3 (PZN-xPT) for compositions near the morphotropic phase boundary (MPB). High-resolution diffraction measurements using CuK αx-rays

Heralding single photons from a high-Q silicon microdisk

November 10, 2016
Author(s)
Xiyuan Lu, Steven Rogers, Thomas Gerrits, Wei Jiang, Sae Woo Nam, Qiang Lin
Integrated quantum photonics has recently attracted considerable attention due to the promise of realizing chip-scale quantum information processing with unprecedented capability and complexity. Their implementation relies essentially on a high-quality

Integration of Redox-Active Diruthenium-based Molecular Layer onto Electrodes for Memory Device Applications

November 10, 2016
Author(s)
Sujitra J. Pookpanratana, Hao Zhu, Joseph W. Robertson, Sean Natoli, Emily G. Bittle, Curt A. Richter, Tong Ren, Qiliang Li, Christina A. Hacker
Attaching and integrating electrochemically-active molecules to a variety of different surfaces is of importance for applications in catalysis, memory devices, and molecular electronics. With the increasing demand for personal electronics, growth in Flash

Liquid Chromatography with Absorbance Detection and with Isotope-Dilution Mass Spectrometry for Determination of Isoflavones in Soy Standard Reference Materials

November 10, 2016
Author(s)
Melissa M. Phillips, Mary Bedner, Manuela Reitz, Carolyn Q. Burdette, Michael A. Nelson, James H. Yen, Lane C. Sander, Catherine A. Rimmer
Two independent analytical approaches, based on liquid chromatography with absorbance detection and liquid chromatography with mass spectrometric detection, have been developed for determination of isoflavones in soy materials. These two methods yield

Reduction of Domain Spacing and Interfacial Width in Fast Ordering Nanofilled Copolymer Films by Direct Immersion Annealing

Author(s)
Maria Monica Castellanos Mantilla, Nicholas J. Clark, Max C. Watson, Susan Krueger, Arnold McAuley, Joseph Curtis
Small-angle scattering is a powerful technique to study molecular conformation and interactions in a variety of systems. Recent work has questioned the validity of analyzing small-angle scattering data of protein solutions with models from the colloidal

The 2016 revision of ISO 1 Standard reference temperature for the specification of geometrical and dimensional properties

November 10, 2016
Author(s)
Steven D. Phillips, Craig M. Shakarji, Alessandro Balsamo, Michael Krystek, Edward P. Morse
This paper discusses the recently published 2016 (third edition) of ISO 1. While the value of the standard reference temperature remains unchanged at 20 C, definitions for the reference temperature and standard reference temperature are now included. This

BLER Performance Evaluation of LTE Device-to-Device Communications

November 9, 2016
Author(s)
Jian Wang, Richard A. Rouil
Long-Term Evolution (LTE) supporting Device-to-Device (D2D) communication is a feature introduced in 3rd Generation Partnership Project (3GPP) release 12. D2D communication is critical in public safety applications, which enables communication among first

Towards a generalized energy prediction model for machine tools

Raunak Bhinge, Jinkyoo Park, Kincho H. Law, David Dornfeld, Moneer Helu, Sudarsan Rachuri
Energy prediction of machine tools can deliver many advantages to a manufacturing enterprise, ranging from energy-efficient process planning to machine tool monitoring. Physics-based energy prediction models have been proposed in the past to understand the

Assessing the Impact of NIST's Forensic Publications and Collaborations

November 8, 2016
Author(s)
Susan L. Makar, Amanda J. Malanowski
Forensics at the National Institute of Standards and Technology (NIST) crosses many disciplines and includes computer forensics, firearms analysis, trace analysis, and forensic biometrics, including fingerprints and DNA analysis. This research and the

Comparison of CBED and ABF Atomic Imaging for GaN Polarity Determination

November 8, 2016
Author(s)
Alexana Roshko, Matthew D. Brubaker, Paul T. Blanchard, Kristine A. Bertness, Todd E. Harvey, Igor Levin, R.H. Geiss
A comparison of two electron microscopy techniques used to determine the polarity of GaN nanowires is presented. The techniques are convergent beam electron diffraction (CBED) in TEM mode and annular bright field (ABF) imaging in aberration corrected STEM
