Tightly Confined Surface Acoustic Waves as Microwave-to-Optical Transduction Platforms in the Quantum Regime

September 26, 2022
Author(s)
Ryan DeCrescent, Zixuan Wang, Poolad Imany, Robert Boutelle, Corey McDonald, Travis Autry, John Teufel, Sae Woo Nam, Richard Mirin
Surface acoustic waves (SAWs) coupled to quantum dots (QDs), trapped atoms and ions, and point defects have been proposed as quantum transduction platforms, yet the requisite coupling rates and cavity lifetimes have not been experimentally established

Liquid-Phase Speed of Sound and Vapor-Phase Density of Difluoromethane

September 23, 2022
Author(s)
Aaron Rowane, Elizabeth Rasmussen, Mark O. McLinden
Difluoromethane (HFC-32, DFM), with a global warming potential (GWP) of 677, is of interest as a pure refrigerant and as a component in low-GWP refrigerant mixtures. Additionally, difluoromethane has recently been identified as a safe, liquefied-gas

Primary standardization of 212Pb activity by liquid scintillation counting

September 22, 2022
Author(s)
Denis E. Bergeron, Jeffrey T. Cessna, Ryan P. Fitzgerald, Lizbeth Laureano-Perez, Leticia Pibida, Brian E. Zimmerman
An activity standard for 212Pb in equilibrium with its progeny was realized, based on triple-to-double coincidence ratio (TDCR) liquid scintillation (LS) counting. A Monte Carlo-based approach to estimating uncertainties due to nuclear decay data

Reproducible Sorbent Materials Foundry for Carbon Capture at Scale

September 22, 2022
Author(s)
Austin McDannald, Howie Joress, Brian DeCost, Avery Baumann, A. Gilad Kusne, Kamal Choudhary, Taner N. Yildirim, Daniel Siderius, Winnie Wong-Ng, Andrew J. Allen, Christopher Stafford, Diana Ortiz-Montalvo
We envision an autonomous sorbent materials foundry (SMF) for rapidly evaluating materials for direct air capture of carbon dioxide ( CO2), specifically targeting novel metal organic framework materials. Our proposed SMF is hierarchical, simultaneously

Derivable genetic programming for two-dimensional colloidal materials

September 21, 2022
Author(s)
Nathan Mahynski, Bliss Han, Daniel Markiewitz, Vincent K. Shen
We describe a method for deriving surface functionalization patterns for colloidal systems that can induce self-assembly into any chosen periodic symmetry at a planar interface. The result is a sequence of letters, s ∈ A,T,C,G}, or a gene, that describes

Magnetic Characterization of Electrodeposited Pt1-xNix Alloy Films: Influence of Deposition Potential and the Presence of Boric Acid

September 21, 2022
Author(s)
Eric Rus, Eduardo De Lima Correa, Evan Groopman, Todd Williamson, Hussein Hijazi, Leila Kasaei, Leonard Feldman, Cindi L. Dennis, Thomas P. Moffat
Pt1-xNix (x = 0.25 to 0.92) thin films were examined for possible application as temperature sensing magnetic reporters. The alloys were prepared by charge-limited potentiostatic electrodeposition from aqueous chloride-based solutions in the presence and
