Topology as a limiting factor in mechanical properties for disordered networks

March 5, 2024
Author(s)
Marcos Reyes-Martinez, Edward Barron III, Dohgyu Hwang, Christopher Soles, Michael Bartlett, Edwin Chan
Disordered networks are ubiquitous in both the natural and synthetic worlds. Depending on the application, some are extremely soft while others are rigid. However, how network topology and intrinsic material properties combine to control deformation and

Uniform Laws and Regulations in the Areas of Legal Metrology and Fuel Quality

March 5, 2024
Author(s)
John McGuire, David Sefcik, Lisa Warfield, Yvonne Branden, Katrice Lippa
NIST Handbook 130 includes a compilation of model laws and regulations and related interpretations and guidelines designed to encourage uniformity in adoption and implementation of weights and measures laws and regulations. The model laws and regulations

Bottom-up Au Filling of Trenches in Curved Wafers

March 4, 2024
Author(s)
Daniel Josell, Thomas P. Moffat, Thomas Gnaupel-Herold, David Raciti, Martin Stauber, Yu Q, Liyang Chen, M Rawlik, Marco Stampanoni, Lucia Romano
A 〖Bi〗^(3+)-stimulated Au electrodeposition process in slightly alkaline 〖Na〗_3 Au(〖SO〗_3 )_2+〖Na〗_2 〖SO〗_3 electrolytes has been previously demonstrated for void-free extreme bottom-up filling of trenches with aspect ratios (height/width) exceeding 60 in

Isotopic effects on in-plane hyperbolic phonon polaritons in MoO3

March 4, 2024
Author(s)
Jeremy Schultz, Sergiy Krylyuk, Jeffrey Schwartz, Albert Davydov, Andrea Centrone
Hyperbolic phonon polaritons (HPhPs), hybrids of light and lattice vibrations in polar dielectric crystals, empower nano-photonic applications by enabling the confinement and manipulation of light at the nanoscale. Molybdenum trioxide (α-MoO3) is a

Reduction-Induced Magnetic Behavior in LaFeO3-d Thin Films

Author(s)
Nathan Arndt, Eitan Hershkovitz, Labdhi Shah, Kristoffer Kjaernes, Chao-Yao Yang, Purnima Balakrishnan, Mohammed Shariff, Shaun Tauro, Daniel Gopman, Brian Kirby, Alexander Grutter, Thomas Tybell, Honggyu Kim, Ryan Need
The effect of oxygen reduction on the magnetic properties of LaFeO3−δ (LFO) thin films was studied to better understand the viability of LFO as a candidate for magnetoionic memory. Differences in the amount of oxygen lost by LFO and its magnetic behavior

Debye-Waller Effects in Bethe-Salpeter Calculations

March 3, 2024
Author(s)
Eric Shirley, Joseph Woicik
We present a method to incorporate Debye-Waller effects on core-excitation spectra in methods other than real-space multiple scattering formulations. The method draws ideas from multiple-scattering theory to realize effects of variations in interatomic
