Harrison M. Skye, Piotr A. Domanski, Mark O. McLinden, Valeri I. Babushok, Ian Bell, Tara Fortin, Michael Hegetschweiler, Marcia L. Huber, Mark A. Kedzierski, Dennis Kim, Lingnan Lin, Gregory T. Linteris, Stephanie L. Outcalt, Vance (Wm.) Payne, Richard A. Perkins, Aaron Rowane
Non-flammable, lower global-warming-potential (GWP) refrigerants are needed to replace HFC-134a (GWP=1300) in military equipment. We previously used thermodynamic cycle simulations to screen 100 000+ refrigerant blends and identified 23 candidate

Mid-Infrared, Near-Infrared, and Visible Nanospectroscopy of Hydrogen-Intercalated MoO3

August 21, 2023
Author(s)
Jeffrey Schwartz, Sergiy Krylyuk, Devon Jakob, Albert Davydov, Andrea Centrone
Control over the local chemical composition and spatial heterogeneities in nanomaterials provides a means to impart new functions and to tailor their properties in many applications. For two-dimensional (2D) van der Waals materials, intercalation is one

RECENT DEVELOPMENTS IN ONTOLOGY STANDARDS AND THEIR APPLICABILITY TO BIOMANUFACTURING

August 21, 2023

Milos Drobnjakovic, Boonserm Kulvatunyou, Vijay Srinivasan, Simon P. Frechette
ISO and IEC have jointly initiated, and recently issued, a series of standards (the ISO/IEC 21838 series) for top-level ontologies. These standards have been used by industrial consortia to develop and disseminate standards for mid-level ontologies to ease

Skyrmion-Excited Spin-Wave Fractal Networks

Nan Tang, W. L. N. C. Liyanage, Sergio A. Montoya, Sheena Patel, Lizabeth J. Quigley, Alexander Grutter, Michael R. Fitzsimmons, Sunil Sinha, Julie A. Borchers, Eric E. Fullerton, Lisa Debeer-Schmitt, Dustin A. Gilbert
Magnetic skyrmions exhibit unique, technologically relevant pseudo-particle behaviors which arise from their topological protection, including well-defined, three-dimensional breathing and gyration modes which occur at microwave frequencies. During dynamic

Fabrication of Specimens for Atom Probe Tomography using a Combined Gallium and Neon Focused Ion Beam Milling Approach

August 16, 2023
Author(s)
Frances Allen, Paul Blanchard, David Pappas, Russell Lake, Deying Xia, John Notte, Ruopeng Zhang, Andrew Minor, Norman A. Sanford
We demonstrate a new focused ion beam sample preparation method for atom probe tomography. The key aspect of the new method is that we use a neon ion beam for the final tip shaping after conventional annulus milling using gallium ions. This dual-ion

Impact of Dynamic Prices on Distribution Grid Power Quality

August 16, 2023
Author(s)
David Holmberg, Thomas Roth, Farhad Omar
Dynamic price signals may provide a way to support integration of customer distributed energy resources (DER) into the electric grid and to help manage DER flexibility to support distribution system and bulk grid needs. Use of DER flexibility includes peak
