Entropic modulation of divalent cation transport

September 22, 2025
Author(s)
Yechan Noh, Demian Riccardi, Alexander Smolyanitsky
Aqueous cations permeate subnanoscale pores by crossing free energy barriers dominated by competing enthalpic contributions from transiently decreased ion-solvent and increased ion-pore electrostatic interactions. This commonly accepted view is rooted in

Author(s)
Jie Yu, Pascale Lakey, Jenna Ditto, Han Huynh, Michael Link, Dustin Poppendieck, Stephen Zimmerman, Xing Wang, Delphine Farmer, Marina Vance, Jonathan Abbatt, Manabu Shiraiwa
The total partitioning capacity of indoor surface reservoirs determines the mechanism by which humans receive nondietary exposure to organic contaminants, via inhalation, dermal uptake, and dust ingestion. And yet, this capacity is largely unknown. Surface

2025 NIST GenAI Text Challenge Evaluation Plan

September 18, 2025
Author(s)
Seungmin Seo, Hariharan Iyer, Yooyoung Lee
The NIST Generative AI (GenAI) Text Challenge is an evaluation program designed to probe the capabilities and limitations of generative AI models from three complementary perspectives: Generator, Prompter, and Discriminator. The challenge will focus on two

NIST Special Publication 800-227, Recommendations for Key-Encapsulation Mechanisms

September 18, 2025
Author(s)
Gorjan Alagic, Elaine Barker, Lidong Chen, Dustin Moody, Angela Robinson, Hamilton Silberg, Noah Waller
A key-encapsulation mechanism (KEM) is a set of algorithms that can be used by two parties under certain conditions to securely establish a shared secret key over a public channel. A shared secret key that is established using a KEM can then be used with

PMSE Centennial: Celebration of Success and New Frontiers in Polymer Materials Science and Engineering

In 2024, the American Chemical Society (ACS) Division of Polymeric Materials: Science and Engineering (PMSE) marked celebrated its centennial. This historic occasion was marked at the 2024 Spring ACS Meeting in New Orleans with a Centennial Symposium

Addressing Visibility Challenges with TLS 1.3 within the Enterprise

September 17, 2025
Author(s)
William Newhouse
The Transport Layer Security (TLS) protocol is widely deployed to secure network traffic. TLS 1.3 has been strengthened so that even if a TLS-enabled server is compromised, the contents of its previous TLS communications are still protected—also known as

Estimating the Costs and Performance of Enhanced Building Design: A Case Study of Functional Recovery for New Buildings

September 17, 2025
Author(s)
Sherief Elsibaie, Yating Zhang, Juan Fung, Dustin Cook, Siamak Sattar, Peter Morris, Henry Burton, David Welch, Kamiar Anaraki
This report details the development of different structural design building archetypes and other seismic enhancements, the cost estimation process applied to those archetypes, and the economic implications and estimation of differing functional recovery

Report on the May 2025 NIST Measurement Week: Realization of an OSAC draft Interim Performance Assessment for Terrestrial Laser Scanners Used by Law Enforcement Agencies

September 17, 2025
Author(s)
Balasubramanian Muralikrishnan, Katharine Shilling, Mary Gregg, Vincent Lee, Jason Keller, Erin Casey, Eugene Liscio, Bryon O'Neil, Mike Russ, Toby Terpstra
This report describes a terrestrial laser scanner (TLS) testing event, the NIST Measurement Week, held at the National Institute of Standards and Technology (NIST) during the week of May 12-16, 2025. The Crime Scene Investigation and Reconstruction (CSIR)

Topological Initialization for Multidimensional Scaling

September 16, 2025
Author(s)
Melinda Kleczynski, Anthony Kearsley
Multidimensional scaling is a popular technique for visualizing dissimilarities between objects in complex datasets. For a single dataset, different initial configurations for multidimensional scaling may produce representations with qualitatively
