This paper presents a new wide-ranging reference correlation for the viscosity of argon, incorporating recent ab initio dilute gas calculations and critically evaluated experimental data. The correlation is designed to be used with a high-accuracy

Size-exclusion chromatography with multi-angle static light scattering

June 26, 2025
Author(s)
Andre Striegel, Amandaa Brewer, Claudia Zielke
Size-exclusion chromatography coupled with multi-angle static light scattering (SEC/MALS) is a combined separation and detection technique that is principally used for determining the molar mass of natural and synthetic macromolecules and colloidal

Description of the electronic structure of oxyhemoglobin using Fe L-edge X-ray absorption spectroscopy

June 11, 2025
Author(s)
Augustin Braun, Charles Titus, Michael Baker, Max Waters, James Yan, Sang-Jun Lee, Dennis Nordlund, William Doriese, Galen O'Neil, Daniel Schmidt, Daniel Swetz, Joel Ullom, Kent Irwin, Edward Solomon
The electronic structure of oxyhemoglobin (oxyHb), the O2-bound form of the oxygen carrier, has been controversial since the discovery of its diamagnetism in 1936. This study uses partial fluorescence yield Fe L-edge X-ray absorption spectroscopy (XAS) in

Uranium Particle Age Dating, Aggregation, and Model Age Best Estimators

June 9, 2025
Author(s)
Evan Groopman, Todd Williamson, Timothy Pope, Michael Bronikowski, Spencer M. Scott, Matthew Wellons
We present important aspects of uranium particle age dating by Large-Geometry Secondary Ion Mass Spectrometry (LG-SIMS) that can introduce bias and increase model age uncertainties, especially for small, young, and/or low-enriched particles. This metrology

Examining Generalizability of AI Models for Catalysis

June 7, 2025
Author(s)
Kamal Choudhary, Shih Han Wang, Hongliang Xin, Luke Achenie
In this work, we investigate the generalizability of problem-specific machine-learning models for catalysis across different datasets and adsorbates, and examine the potential of unified models as pre-screening tools for density functional theory
