Betraying excitonic processes and chemical bonding in MoS2 by x-ray-absorption near-edge structure and resonant-Auger electron emission

March 10, 2021
Author(s)
Joseph Woicik, Nicholas F. Quackenbush, Conan Weiland, Eric L. Shirley, Abdul K. Rumaiz, Michael T. Brumbach, James M. Ablett
Electron core-hole processes at absorption edges sport several signatures, primarily in the form of bound states and/or excitonic enhancement. Through analysis of the resonant-Raman Auger effect for the 2-dimensional transition-metal dichalcogenide MoS2

Workforce Framework for Cybersecurity (NICE Framework)

November 16, 2020
Author(s)
Rodney Petersen, Danielle Santos, Karen Wetzel, Matthew Smith, Greg Witte
This publication from the National Initiative for Cybersecurity Education (NICE) describes the Workforce Framework for Cybersecurity (NICE Framework), a fundamental reference for describing and sharing information about cybersecurity work. It expresses

Coherent Optical Clock Down-Conversion for Microwave Frequencies with 10-18 Instability

May 22, 2020
Author(s)
Takuma Nakamura, Josue Davila-Rodriguez, Holly Leopardi, Jeffrey Sherman, Tara Fortier, Xiaojun Xie, Joe C. Campbell, Will McGrew, Xiaogang Zhang, Youssef Hassan, Daniele Nicolodi, Kyle Beloy, Andrew Ludlow, Scott Diddams, Franklyn Quinlan
Optical atomic clocks are poised to redefine the SI second, thanks to stability and accuracy more than one hundred times better than the current microwave atomic clock standard. However, the best optical clocks have not seen their performance transferred

Frequency-comb spectroscopy on pure quantum states of a single molecular ion

March 27, 2020
Author(s)
Chin-wen Chou, Alejandra L. Collopy, Christoph Kurz, Yiheng Lin, Michael E. Harding, Philipp N. Plessow, Tara M. Fortier, Scott A. Diddams, Dietrich G. Leibfried, David R. Leibrandt
Spectroscopy is a powerful tool for studying molecular properties and is commonly performed on large thermal ensembles of molecules that are perturbed by motional shifts and interactions with the environment and one another, resulting in convoluted spectra

NIST Big Data Interoperability Framework: Volume 2, Big Data Taxonomies

November 18, 2019
Author(s)
Wo L. Chang, Nancy Grady
Big Data is a term used to describe the large amount of data in the networked, digitized, sensor-laden, information-driven world. While opportunities exist with Big Data, the data can overwhelm traditional technical approaches and the growth of data is

Reversible Epitaxial Electrodeposition of Metals in Battery Anodes

November 1, 2019
Author(s)
Jingxu Zheng, Qing Zhao, Tian Tang, Jiefu Yin, Calvin D. Quilty, Genesis D. Renderos, Xiaotun Liu, Yue Deng, Lei Wang, David C. Bock, Cherno Jaye, Esther S. Takeuchi, Kenneth J. Takeuchi, Amy C. Marschilok, Lynden A. Archer
The propensity of metals to form irregular and non-planar electrodeposits at liquid/solid interfaces has emerged as a fundamental barrier to high-energy, rechargeable batteries that utilize metal anodes. We report an epitaxial mechanism to regulate

A stroboscopic approach to trapped-ion quantum information processing with squeezed phonons

October 24, 2019
Author(s)
Wenchao Ge, Brian C. Sawyer, Joseph W. Britton, Kurt Jacobs, Michael Foss-Feig, John Bollinger
In trapped-ion quantum information processing, interactions between spins (qubits) are mediated by collective modes of motion of an ion crystal. While there are many different experimental strategies to design such interactions, they all face both

10986-1 IEEE P4001-Progress Towards a Hyperspectral Standard

May 14, 2019
Author(s)
David Allen
Hyperspectral imaging is an innovative and exciting technology that holds incredible diagnostic, scientific and categorization power. Current industry innovation is a testament to the creative power and imagination of the diverse community seeking to

Mid-infrared dual-comb spectroscopy of volatile organic compounds across long open-air paths

February 5, 2019
Author(s)
Gabriel Ycas, Fabrizio Giorgetta, Kevin Cossel, Eleanor M. Waxman, Esther Baumann, Nathan Newbury, Ian Coddington
Open-path measurements of atmospheric gas species in the air, including volatile organic compounds, are essential to quantify emissions from sources like oil and gas, forest fires, and industry. Here, we extend open-path dual-comb spectroscopy to probe the

Ba8Cu16As30: A cationic-framework clathrate-I arsenide

August 10, 2018
Author(s)
Kaya Wei, Artem R. Khabibullin, Dean Hobbis, Winnie Wong-Ng, Tieyan Chang, SuYin G. Wang, Igor Levin, Yu-Sheng Chen, Lilia M. Woods, George S. Nolas
Single crystals of clathrate-I Ba8Cu16As30 have been synthesized, and their structure and electronic properties deter-mined using synchrotron-based X-ray diffraction and first principles calculations. The structure is confirmed to be cubic and defined by a

NIST Big Data Interoperability Framework: Volume 2, Big Data Taxonomies [Version 2]

June 26, 2018
Author(s)
Wo L. Chang, Nancy Grady, NBD-PWG NIST Big Data Public Working Group
Big Data is a term used to describe the large amount of data in the networked, digitized, sensor- laden, information-driven world. While opportunities exist with Big Data, the data can overwhelm traditional technical approaches and the growth of data is

Stateful characterization of resistive switching TiO2 with electron beam induced currents

December 7, 2017
Author(s)
Brian D. Hoskins, Gina C. Adam, Evgheni Strelcov, Nikolai B. Zhitenev, Andrei A. Kolmakov, Dmitri B. Strukov, Jabez J. McClelland
Metal oxide resistive switches have become increasingly important as possible artificial synapses in next generation neuromorphic networks. Nevertheless, there is still no codified set of tools for studying fundamental properties of the devices. To this

The SI and Quantum Metrology

December 1, 2017
Author(s)
Carl J. Williams
The United States’ National Institute of Standards and Technology (NIST) is playing a major role in the worldwide effort to base the International System of Units (SI) on fundamental constants. In many cases, units will be redefined in terms of invariant

Optomechanical Quantum Correlations at Room Temperature

June 23, 2017
Author(s)
Thomas P. Purdy, Karen E. Grutter, Kartik A. Srinivasan, Jacob M. Taylor
By shining laser light through a nanomechanical beam, we measure the beam’s thermally driven vibrations and perturb its motion with optical forces at a level dictated by the Heisenberg measurement-disturbance uncertainty relation. Such quantum effects are
