Linking excess entropy and acentric factor in spherical fluids

September 9, 2024
Author(s)
Tae Jun Yoon, Ian Bell
Introduced by Kenneth Pitzer in 1955, the acentric factor (ω) became a standard quantity in chemical thermodynamics, representing a molecule's "shape" effect on the deviation from the corresponding state behavior. Nevertheless, its interpretation remains

Statistical study and parallelization of multiplexed single-electron sources

September 9, 2024
Author(s)
S Norimoto, P See, N Schoinas, I Rungger, Tommy Boykin, Michael Stewart, J. P. Griffiths, C. Chen, D. A. Ritchie, M. Kataoka
Increasing electric current from a single-electron source is a main challenge in an effort to establish the standard of the ampere defined by the fixed value of the elementary charge e and operation frequency f . While the current scales with f , due to an

Value assignment and uncertainty evaluation for certified reference gas mixtures

September 9, 2024
Author(s)
Christina Cecelski, Jennifer Carney, Antonio Possolo
The procedures used to assign values to certified reference gas mixtures and to evaluate their associated uncertainties, which are described in ISO 6143, and that were variously improved by Guenther and Possolo (Anal Bioanal Chem 399:489–500, 2011. 10.1007

Random and systematic uncertainty in ship-based seawater carbonate chemistry observations

Seawater carbonate chemistry observations are increasingly necessary to study a broad array of oceanographic challenges such as ocean acidification, carbon inventory tracking, and assessment of marine carbon dioxide removal strategies. As a result, efforts

Foundry manufacturing of octave-spanning microcombs

September 6, 2024
Author(s)
Jizhao Zang, Haixin Liu, Travis Briles, Scott Papp
Soliton microcombs provide a chip-based, octave-spanning source for self-referencing and optical metrology. We use a silicon nitride integrated photonics foundry to manufacture 280 single-chip solutions of octave-spanning microcombs on a wafer. By group

Harold Hatch, Christina Bergonzo, Marco Blanco, Guangcui Yuan, Sergei Grudinin, Mikael Lund, Joseph E. Curtis, Alexander Grishaev, Yun Liu, Vincent K. Shen
We develop a multiscale coarse-grain model of the NIST Monoclonal Antibody Reference Material 8671 (NISTmAb) to enable systematic computational investigations of high-concentration physical instabilities such as phase separation, clustering, and

CHARACTERIZATION OF MICROWAVE BLACKBODY WITH MONOSTATIC MEASUREMENT

September 5, 2024
Author(s)
Dazhen Gu, Jonah Smith, Adam Whitney, Omar Khatib, Natalie Rozman, Amanda Gregg, Willie Padilla, William Deal, Steven Reising
This paper describes a characterization method for measuring the reflectivity of blackbodies used as calibration devices in spaceborne instruments. The fundamental measurement principle is based on the scattering matrix theory. A monostatic apparatus has
