Rabindranath Bag, Sachith Dissanayake, Han Yan, Zhenzhong Shi, David Graf, Eun S. Choi, Casey Marjerrison, Franz Lang, Tom Lancaster, Yiming Qiu, Wangchun Chen, Stephen J. Blundell, Andriy H. Nevidomskyy, Sara Haravifard
Recently a new class of quantum magnets, the so-called breathing pyrochlore systems, have attracted much attention due to their potential to host exotic emergent phenomena. Here, we present magnetometry, thermal, muon-spin relaxation, and polarized

Machine tool calibration: Measurement, modeling, and compensation of machine tool errors

The field of neuromorphic computing holds great promise in terms of advancing computing efficiency and capabilities by following brain-inspired principles. However, the rich diversity of techniques employed in neuromorphic research has resulted in a lack

Size-exclusion chromatography

April 20, 2023
Author(s)
Andre Striegel
Over the past half-century, size-exclusion chromatography (SEC) has become the premier method by which to determine the molar mass (M) averages and the molar mass distribution (MMD) of natural and synthetic macromolecules. When coupled to a multiplicity of

Who Is That? Perceptual Expertise on Other-Race Face Comparisons, Disguised Face Comparisons, and Face Memory

April 20, 2023
Author(s)
Amy Yates, Jacqueline Cavazos, Geraldine Jeckeln, Ying Hu, Eilidh Noyes, Carina Hahn, Alice O'Toole, P. Jonathon Phillips
Forensic facial specialists identify faces more accurately than untrained participants on tests using high quality images of faces. Whether this superiority holds in more challenging conditions is not known. Here, we measured performance for forensic

Correlating the Diffusion of Water in Model Polyamides with Controlled Crosslink Densities to the Performance in Reverse Osmosis Membranes for Desalination

Author(s)
Velencia Witherspoon, Kanae Ito, Chad R. Snyder, Madhusudan (Madhu) Tyagi, Tyler Martin, Peter Beaucage, Ryan Nieuwendaal, Richard Vallery, David Gidley, Jeffrey Wilbur, Dean Welsh, Christopher Stafford, Christopher Soles
To elucidate robust design cues for improving the active polyamide (PA) filtration layers in reverse osmosis (RO) membrane for desalination, we systematically reduce the cross-link density of a PA network based on m-phenylene diamine by substituting a

ITS10 Conference Digest

Author(s)
Christopher W. Meyer, Kathryn Miller, Weston L. Tew, Howard W. Yoon
The 10th International Temperature Symposium (ITS10) was held in Anaheim California on April 3rd to 7th, 2023. More than 180 abstracts were received and accepted and 159 of those were presented at the symposium. This document is a record of the symposium

Dynamics of the Extended and Intermediate Range Order in Model Polymer Electrolyte Poly(Ethylene Oxide) and Lithium Bis(Trifluoromethanesulfonyl)imide

April 17, 2023
Author(s)
Peter Falus, Antonio Faraone, Stephan Forster, Kunlun Hong, Michael Ohl
The dynamics of lithium ions and polymer chains were investigated at the molecular scale in the model polymer electrolyte Poly (Ethylene Oxide) (PEO)/Lithium bis(trifluoromethanesulfonyl)imide as a function of temperature. This system is known to present

Investigating the Effect of Medium Chain Triglycerides on the Elasticity of Pulmonary Surfactant

In recent years, vaping has increased in both popularity and ease of access. This has led to an outbreak of a relatively new condition known as e-cigarette/vaping-associated lung injury (EVALI). This injury can be caused by physical interactions between

Symplectic geometry and circuit quantization

Author(s)
Andrew Osborne, Trevyn Larson, Sarah Jones, Raymond Simmonds, Andras Gyenis, Andrew Lucas
Circuit quantization is an extraordinarily successful theory that describes the behavior of quantum circuits with high precision. The most widely used approach of circuit quantization relies on introducing a classical Lagrangian whose degrees of freedom

Modeling Approach for the Design of the NIST Neutron Source

The Statistic and Deterministic Kettle

April 16, 2023

Yaniv Shaposhnik, Abdullah Weiss, Dagistan Sahin
In some accident scenarios, a nuclear reactor could be assumed to be similar to a kettle. Namely, the water inside the core, or in this case in the kettle, is experiencing heating, and at some point, for a non-boiling reactor, the safety boundary may be
