Dynamic and Static Grain Growth During the Superplastic Deformation of 3Y-TZP

March 1, 1998
Author(s)
J Seidensticker, M J. Mayo
While phenomenological theories of superplasticity have often suffered from the fact that a single phenomenological law is not universally applicable to all superplastic systems, it is shown that a universal dynamic grain growth law does apply. The law is

Backdraft Phenomena. Final Report. 1990-1992.

June 1, 1994
Author(s)
Charles M. Fleischmann
The purpose of this project was to develop a fundamental physical understanding of backdraft phenomena. The research was divided into three phases: exploratory simulations, gravity current modeling, and quantitative backdraft experiments. The primary goal

Structure of Inhibited Counterflowing Nonpremixed Flames

May 11, 1993
Author(s)
Anthony P. Hamins, M H. Yang, I K. Puri
Recent international agreements call for a halt to the manufacture of CF3Br (Halon 1301), a commonly used halon fire suppressant, due to its high ozone-depletion potential. Ideally, the search for replacement compounds should be guided by fundamental

Coexistence of Superconductivity and Antiferromagnetism in Topological Magnet MnBi2Te4 Films

July 3, 2024
Author(s)
Wei Yuan, Zi-Jie Yan, Hemian Yi, Zihao Wang, Stephen Paolini, Yi-Fan Zhao, Ling-Jie Zhou, Annie G. Wang, Ke Wang, Thomas Prokscha, Zaher Salman, Andreas Suter, Purnima Balakrishnan, Alexander Grutter, Laurel E. Winter, John Singleton, Moses H. Chan, Cui-Zu Chang
The interface of two materials can harbor unexpected emergent phenomena. One example is interface-induced superconductivity. In this work, we employ molecular beam epitaxy to grow a series of heterostructures formed by stacking together two

Scalable Quantum Logic Spectroscopy

November 2, 2022
Author(s)
Kaifeng Cui, Jose Valencia, Kevin Boyce, Ethan Clements, David Leibrandt, David Hume
In quantum logic spectroscopy (QLS), one species of trapped ion is used as a sensor to detect the state of an otherwise inaccessible ion species. This extends precision measurements to a broader class of atomic and molecular systems for applications like

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

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
