Electron transport in bilayer graphene nanoconstrictions patterned using atomic force microscope nanolithography

March 20, 2025
Author(s)
Robert Rienstra, Nishat Sultana, En-Min Shih, Evan Stocker, Kenji Watanabe, Takashi Taniguchi, Curt Richter, Joseph Stroscio, Nikolai Zhitenev, Fereshte Ghahari Kermani
Here we report on low temperature transport measurements of encapsulated bilayer graphene nano constrictions fabricated employing electrode-free AFM-based local anodic oxidation (LAO) nanolithography. This technique allows for the creation of constrictions

Quantitative hyperspectral microscopy from single cell to tissue imaging

March 20, 2025

Jeeseong Hwang
This paper showcases recent research at NIST on quantitative hyperspectral imaging of single cells and tissues with a variety of imaging contrasts including scattering reflectance, transmission, and dark-field and with supervised and unsupervised data

Suspect Screening of Per- and Polyfluoroalkyl Substances in New Firefighter Turnout Gear Textiles

March 20, 2025
Author(s)
Andrew Maizel, Andre Thompson, Benjamin Place, Alix Rodowa, Jessica Reiner, Audrey Tombaugh, Halen Solomon, Brittany Stinger, Michelle Donnelly, Rick Davis
Firefighter turnout gear provides protection from exposure to flame, heat, and liquids, but has also been found to contain numerous per- and polyfluoroalkyl substances (PFAS). Previous examinations of PFAS in firefighter turnout gear have predominantly

BRDF measurements of ultra-black materials with THz quantum cascade lasers

March 19, 2025
Author(s)
Patrick McArdle, Bradley Pelz, Christopher Yung, Nathan Tomlin, John Lehman, Michelle Stephens
In this work we describe the use of a THz quantum cascade laser (QCL) to perform bi-directional reflectance distribution (BRDF) measurements. In particular we are interested in the reflectance properties of ultra-black absorbers for use in detector devices

METROLOGY FOR MRI: THE FIELD YOU'VE NEVER HEARD OF

March 19, 2025
Author(s)
Kathryn Keenan, Stephen Russek, Matt Hall
Quantitative MRI has been an active area of research for decades and has produced a huge range of approaches with enormous potential for patient benefit. In many cases, however, there are challenges with reproducibility which has hampered clinical

Molecules to Masterpieces: Bridging Materials Science and the Arts

March 19, 2025
Author(s)
Ferdinand Kohle, Hiroaki Sai, William Tait, Peter Beaucage, Ethan Susca, R. Thedford, Ulrich Wiesner
Art and materials innovation have always been intertwined, dating back to the earliest human creations. In modern times, however, the increasing specialization of materials science often restricts artists' access to cutting-edge materials. Here, the

The Development of Standards for the Ethical Use of Human Skeletal Remains for Education, Research, and Training in Forensic Anthropology

March 19, 2025
Author(s)
Nicholas Passalacqua, Eric Bartelink, Wendy McQuade, Dawnie Steadman, Donna Boyd, Kate Spradley, Kelly Sauerwein, Ranee Ho
We present a proposed standard regarding the use of contemporary human skeletal remains in education, training, and research contexts in forensic anthropology. This document was generated by the Anthropology subcommittee of the Organization of Scientific

Demonstration of Immunity to 400 *C Forming Gas Annealing in Oxide Semiconductor Transistor via PostMetallization Annealing

March 18, 2025
Author(s)
Yu-Hsin Kuo, Dylan J. Matthews, Shinichiro N. Muramoto, TaeYoung Song, Chengyang Zhang, Xianduo Zhao, Md S. Rahman, Sanghyun Kang, Andres S. Aguirre, Seung M. Lee, Daewon Ha, Sourav Dutta, Theodore Moise, Jayakanth Ravichandran, Shimeng Yu, Alexander Grutter, Suman Datta, Tania Roy, Asif I. Khan
Hydrogen-based annealing processes like forming gas annealing (FGA), widely used in back-end-ofline (BEOL) fabrication, can severely impact the threshold voltage (VTH) and subthreshold swing (SS) stability of amorphous oxide semiconductor (AOS) transistors

Development and characterization of the NISTCHO reference cell line

Author(s)
Hussain Dahodwala, Irfan Hodzic, Alexei Slesarev, Ben Cutak, Alexander Kuzin, Rahul Lal, Jiajian Liu, James Mahon, Rajagopalan Lakshmi Narasimhan, Jaya Onuska, James Ravellette, Kelsey Reger, Sadie Sakurada, Floy Stewart, Trissa Borgschulte, Colette Cote, Kelvin Lee, Zvi Kelman, William Brad O'Dell, Britta Anderson
Well characterized reference materials enable successful collaborations within the scientific community by establishing common reagents for benchmarking studies and reducing the barriers to sharing materials and information. Here, we report the development

Using Temporal Consistency for Compressed Sensing in High-Resolution mmWave Sounding

March 18, 2025
Author(s)
Rudolph Semper, Jack Chuang, Samuel Berweger, Camillo Gentile
Switched phased array systems operating at high sample rates generate large amounts of data during measurements of radio channels, but many scenarios contain only few multipath components. Compressed Sensing suggests in these cases Nyquist-rate samples are

Detection of fractional quantum Hall states by entropy-sensitive measurements

March 17, 2025
Author(s)
Nishat Sultana, Robert Rienstra, K Watanabe, T Taniguchi, Joseph Stroscio, Nikolai Zhitenev, D Feldman, Fereshte Ghahari Kermani
Measurements of the thermopower of a clean two-dimensional electron system is directly proportional to the entropy per charge carrier1 which can probe strongly interacting quantum systems ranging from black holes2 to the fractional quantum Hall effect

Magneto-optics of a charge-tunable quantum dot: Observation of a negative diamagnetic shift

March 17, 2025
Author(s)
Giora Peniakov, A Beck, Eilon Poem, Zu-En Su, Boaz Taitler, Sven Hofling, Garnett Bryant, David Gershoni
We present magneto-optical studies of a self-assembled semiconductor quantum dot in neutral and positively charged states. The diamagnetic shifts and Zeeman splitting of many well identified optical transitions are precisely measured. Remarkably, a
