Author(s)
Yan Jin, Erwan Lucas, Jizhao Zang, Travis Briles, Ivan Dickson, David Carlson, Scott Papp
Control of nonlinear interactions in microresonators enhances access to classical and quantum field states across nearly limitless bandwidth. A recent innovation has been to leverage coherent scattering of the intraresonator pump as a control of group

Infographic on Post-Earthquake Functional Recovery Performance

February 10, 2025
Author(s)
Katherine Johnson, Siamak Sattar, Dustin Cook
In the U.S., building codes and standards have been developed to reduce the likelihood of building collapse but do not address the loss of building functions or recovery times due to earthquakes. When scaled to the community level, negative consequences

NIST Neutron Source Pre-Conceptual Design

February 10, 2025
Author(s)
David Diamond, Abdullah Weiss, Osman Celikten, Jeremy Cook, Dagistan Sahin, Hubert King, Anil Gurgen, Joy Shen
A pre-conceptual design has been completed for a NIST Neutron Source (NNS). It would replace the existing facility at the NIST Center for Neutron Research (NCNR) to enable significantly more thermal and cold neutrons to be used in many more experiments

February 6, 2025
Author(s)
Unay Dorken Gallastegi, Hoover Rueda-Chacon, Martin Stevens, Vivek Goyal
Passive hyperspectral long-wave infrared measurements are remarkably informative about the surroundings, such as remote object material composition, temperature, and range; and air temperature and gas concentrations. Remote object material and temperature

Solvent Structure Controlled SeedGel Formation Investigated using Miscible Binary Solvent

February 6, 2025
Author(s)
Yuyin Xi, Ruipeng Li, William Heller, Wei-Ren Chen, Kunlun Hung, Aurora Zemborain, Yun Liu
The interconnected channels and high specific surface areas have made materials with bicontinuous structures great candidates for energy-related and biomedical applications. Their controllable structures also promise great possibilities for enabling new

Symmetry-breaking induced surface magnetization in non-magnetic RuO2

February 6, 2025
Author(s)
Garnett Bryant, Quoc Dai Ho, Quang To, Ruiqi Hu, Anderson Janotti
Altermagnetism is a newly identified phase of magnetism distinct from ferromagnetism and antiferromagnetism. RuO2 has been considered a prototypical metallic altermagnet with a critical temperature higher than room temperature. Previous interpretations of

H-Bonded Organic Frameworks as Ultrasound-Programmable Delivery Platform

Chelsea Shover, Morgan Godvin, Meghan Appley, Elise Pyfrom, Fernando Montero Castrillo, Karli Hochstatter, Neil Garg, Adam Koncsol, Joseph Friedman, Caitlin Molina, Ruby Romero, Brendan Harshberger, Jordan Spoliansky, Candace Winstead, Edward Sisco
Bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate (BTMPS) belongs to a class of molecules called hindered amine light stabilizers that are used in plastics manufacturing and as adhesives or sealants.1 BTMPS has not been studied in humans or approved for human

A Collection of Dwellings to Represent the U.S. Housing Stock

February 4, 2025
Author(s)
Nathan Lima, Andrew K. Persily, Steven Emmerich
This report presents a comprehensive update to the collection of dwellings used to represent the U.S. housing stock, reflecting changes and trends up to the year 2024. This update aims to ensure the collection remains relevant and accurately mirrors the

Electronic Commensuration of a Spin Moire Superlattice in a Layered Magnetic Semimetal

February 4, 2025
