Status Report on the Third Round of the NIST Post-Quantum Cryptography Standardization Process

July 5, 2022
Author(s)
Gorjan Alagic, David Cooper, Quynh Dang, Thinh Dang, John M. Kelsey, Jacob Lichtinger, Yi-Kai Liu, Carl A. Miller, Dustin Moody, Rene Peralta, Ray Perlner, Angela Robinson, Daniel Smith-Tone, Daniel Apon
The National Institute of Standards and Technology is in the process of selecting public-key cryptographic algorithms through a public, competition-like process. The new public-key cryptography standards will specify additional digital signature, public

Suppression of filament defects in embedded 3D printing

July 5, 2022
Author(s)
Leanne Friedrich, Ross Gunther, Jonathan Seppala
Embedded 3D printing enables the manufacture of soft, intricate structures. In the technique, a nozzle is embedded into a viscoelastic support bath and extrudes filaments or droplets. While embedded 3D printing expands the printable materials space to low

Transition-edge Sensors

July 5, 2022
Author(s)
Douglas Bennett
Near the end of the 20th century, there was renewed excitement about the potential appli- cations of a type of superconducting detector known as the transition-edge sensor (TES). In the intervening decades there has been a paradigm shift from TESs as a

Unraveling the Stable Cathode Electrolyte Interface in all Solid-State Thin-Film Battery Operating at 5 V

July 4, 2022
Author(s)
Ryosuke Shimizu, Diyi Cheng, Jamie Weaver, Minghao Zhang, Bingyu Lu, Thomas Wynn, Randall Burger, Min-cheol Kim, Guomin Zhu, Ying Shirley Meng
Spinel-type LiNi0.5Mn1.5O4 (LNMO) is one of the most promising 5 V-class cathode materials for Li-ion batteries that can achieve high energy density and low production costs. However, in liquid electrolyte cells, the high voltage causes continuous cell

Results from neutron imaging phase change experiments with LH2 and LCH4

July 2, 2022
Author(s)
Kishan Bellur, Ezequiel Medici, Daniel Hussey, David Jacobson, Jacob LaManna, Juscelino Leao, Julia Scherschligt, James Hermanson, Chang Kyoung Choi, Jeffrey Allen
Predicting evaporation and cryo-storage behavior of liquid hydrogen poses a challenge for both terrestrial energy infrastructure and long term space missions. The current understanding of cryogenic phase change and subsequent boil-off is limited, in part

Co-Based Superalloy Morphology Evolution: A Phase Field Study Based on Experimental Thermodynamic and Kinetic Data

July 1, 2022
Author(s)
Carelyn E. Campbell, Ursula R. Kattner, Jonathan E. Guyer, James A. Warren, Wenkun Wu, Peter Voorhees, Olle Heinonen
Cobalt-based superalloys with gamma/gamma prime microstructures off er great promise as candidates for next-generation high-temperature alloys for applications, such as turbine blades. It is essential to understand the thermodynamic and kinetic factors

EXPANSE: A time-of-flight EXPanded Angle Neutron Spin Echo spectrometer at the Second Target Station of the Spallation Neutron Source

July 1, 2022
Author(s)
Changwoo Do, Rana Ashkar, Cristina Boone, Wei-Ren Chen, Georg Ehlers, Peter Falus, Antonio Faraone, Jason Gardner, Van Graves, Thomas Huegle, Reika Katsumata, Darian Kent, Jiao Lin, Bill Mchargue, Bradley D. Olsen, Yangyang Wang, Danielle Wilson, Y. Z.
EXPANSE, an EXPanded Angle Neutron Spin Echo instrument, has been proposed and selected as one of the first suite of instruments to be built at the Second Target Station of the Spallation Neutron Source at the Oak Ridge National Laboratory. This instrument

Graph Neural Network Predictions of Metal Organic Framework CO2 Adsorption Properties

July 1, 2022
Author(s)
Kamal Choudhary, Taner N. Yildirim, Daniel Siderius, A. Gilad Kusne, Austin McDannald, Diana Ortiz-Montalvo
The increasing CO$_2$ level is a critical concern and suitable materials are needed to directly capture such gases from the environment. While experimental and conventional computational methods are useful in finding such materials, they are usually slow
