Quantum-Based Photonic Sensors for Pressure, Vacuum, and Temperature Measurements: A Vison of the Future with NIST on a Chip

September 17, 2021
Author(s)
Jay H. Hendricks, Zeeshan Ahmed, Daniel Barker, Kevin O. Douglass, Stephen Eckel, James A. Fedchak, Nikolai Klimov, Jacob Edmond Ricker, Julia Scherschligt
The NIST on a Chip (NOAC) program's central idea is the idea that measurement technology can be developed to enable metrology to be performed "outside the National Metrology Institute" by the crea-tion of deployed and often miniaturized standards. These

Deterministic Tagging Technology for Device Authentication

September 16, 2021
Author(s)
Jungjoon Ahn, Joseph Kopanski, Yaw S. Obeng, Jihong Kim
This paper discusses the development of a rapid, large-scale integration of deterministic dopant placement technique for encoding information in physical structures at the nanoscale. The doped structures inherit identical and customizable radiofrequency

Machine Learning for Access Control Policy Verification

September 16, 2021
Author(s)
Vincent C. Hu
Access control policy verification ensures that there are no faults within the policy that leak or block access privileges. As a software test, access control policy verification relies on methods such as model proof, data structure, system simulation, and

Metrological Tools for the Reference Materials and Reference Instruments of the NIST Material Measurement Laboratory

Carlos R. Beauchamp, Johanna Camara, Jennifer Carney, Steven J. Choquette, Kenneth D. Cole, Paul C. DeRose, David L. Duewer, Michael Epstein, Margaret Kline, Katrice Lippa, Enrico Lucon, John L. Molloy, Michael Nelson, Karen W. Phinney, Maria Polakoski, Antonio Possolo, Lane C. Sander, John E. Schiel, Katherine E. Sharpless, Michael R. Winchester, Donald Windover
The National Institute of Standards and Technology (NIST), formerly the National Bureau of Standards, was established by the U.S. Congress in 1901 and charged with establishing a measurement foundation to facilitate U.S. and international commerce. NIST

Preparation, Characterization, and Biological Activity of Stability-Enhanced Polyethyleneimine-Conjugated Gold Nanoparticles (Au-PEI@NIST) for Biological Application

September 16, 2021
Author(s)
Tae Joon Cho, Vincent A. Hackley, Feng Yi, David A. LaVan, Vytas Reipa, Alessandro Tona, Bryant C. Nelson, Christopher Sims, Natalia Farkas
In this special publication, we report on a modified synthetic process that results in a stable suspension of Au-PEI nanoparticles, Au-PEI@NIST. Synthesized materials were characterized using an orthogonal approach that included dynamic light scattering

Alternatives to aluminum gates for silicon quantum devices: Defects and strain

September 15, 2021
Author(s)
Ryan Stein, Zachary Barcikowski, Sujitra Pookpanratana, Joshua M. Pomeroy, Michael Stewart
Gate-defined quantum dots (QD) benefit from the use of small grain size metals for gates materials because it aids in shrinking the device dimensions. However, it is not clear what differences arise with respect to process-induced defect densities and

Experimental confirmation of long hyperbolic polariton lifetimes in monoisotopic (10B) hexagonal boron nitride at room temperature

September 14, 2021
Author(s)
Georges Pavlidis, Jeffrey Schwartz, Joseph Matson, Thomas Folland, Song Liu, James Edgar, Joshua Caldwell, Andrea Centrone
Hyperbolic phonon polaritons (HPhPs) enable arbitrarily high confinements, low losses, and directional propagation – providing opportunities from hyperlensing to flat optics, and other advanced nanophotonics applications. In this work, two near-field

Firebrands generated in Shurijo Castle Fire on October 30th, 2019

September 14, 2021
Author(s)
Samuel Manzello, Sayaka Suzuki
A fire started in Shurijo Seiden, or the main hall of Shurijo Castle, Naha-city, Okinawa, Japan on the morning of October 30th, 2019. The fire resulted in loss of 8 structures and many important Okinawan cultural assets. The original Shurijo Castle was

Reference Correlation for the Thermal Conductivity of Ethane-1,2-diol (Ethylene Glycol) from the Triple Point to 475 K and Pressures up to 100 MPa

September 14, 2021
Author(s)
Marko Mebelli, Danai Velliadou, Marc Assael, Konstantinos D. Antoniadis, Marcia L. Huber
We present a new wide-ranging correlation for the thermal of ethane-1,2-diol (ethylene glycol) based on critically evaluated experimental data. The correlation is designed to be used with an existing equation of state, and it is valid from the triple point

Single-photon detection in the mid-infrared up to 10 micron wavelength using tungsten silicide superconducting nanowire detectors
