Quantitative hyperspectral microscopy from single cell to tissue imaging

March 20, 2025
Author(s)
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

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

Scalable and fault-tolerant preparation of encoded k-uniform states

March 18, 2025
Author(s)
Shayan Majidy, Madelyn Cain, Nishad Maskara, Dominik Hangleiter, Michael Gullans
k-uniform states are valuable resources in quantum information, enabling tasks such as teleporta- tion, error correction, and accelerated quantum simulations. However, verifying k-uniformity is as difficult as measuring code distances, and devising fault

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
