Multigas adsorption with single-site cooperativity in a metal-organic framework

November 20, 2025
Author(s)
Kurtis M. Carsch, Henry Z. Jiang, Ryan Klein, Andrew S. Rosen, Peyton Summerhill, Jesse L. Peltier, Adrian J. Huang, Ryan A. Murphy, Matthew N. Dods, Hope A. Silva, Zikri Hasanbasri, Hyunchul Kwon, Sarah H. Karstens, Yuto Yabuuchi, Jonas Boergel, Jordan W. Taylor, Katie R. Meihaus, Karen C. Bustillo, Andrew M. Minor, Kristen A. Persson, Craig Brown, R. D. Britt, Nicholas P. Stadie, Jeffrey Long
Cooperative gas adsorption in metal–organic frameworks (MOFs) is a rare phenomenon that generally involves long-range communication between multiple binding sites. We demonstrate a MOF containing cobalt(II)–methyl sites that selectively and reversibly

Measuring the RCS of Multipoint-Scattering Targets in JCAS Channel Sounding

May 25, 2025
Author(s)
Camillo Gentile, Jack Chuang, Steve Blandino, Jelena Senic, Jihoon Bang, Samuel Berweger
This paper presents a methodology for measuring the radar cross-section (RCS) of a target that scatters power from multiple points on its surface, in the context of joint communication and sensing (JCAS). By leveraging the fine resolution of millimeter

Building a Digital Twin of a CNC Machine Tool

December 18, 2024
Author(s)
Deogratias Kibira, Guodong Shao, Rishabh Venketesh, Matthew Triebe
Developing digital twins for manufacturing applications is challenging due to insufficient modeling frameworks and standardized procedures. As a result, the number of successful digital twin implementations has not caught up with the increasing literature

High-Temperature Carbon Dioxide Capture in a Porous Material with Terminal Zinc Hydride Sites

November 15, 2024
Author(s)
Rachel Rohde, Kurtis Carsch, Matthew Dods, Henry Jiang, Alexandra McIsaac, Ryan Klein, Hyunchul Kwon, Sarah Karstens, Yang Wang, Adrian Huang, Jordan Taylor, Yuto Yabuuchi, Nikolay Tkachenko, Katie Meihaus, Hiroyasu Furukawa, Danielle Yahne, Kaitlyn Engler, Karen Bustillo, Andrew Minor, Jeffrey Reimer, Martin Head-Gordon, Craig Brown, Jeffrey Long
Carbon capture can mitigate point-source carbon dioxide (CO2) emissions, but hurdles remain that impede the widespread adoption of amine-based technologies. Capturing CO2 at temperatures closer to those of many industrial exhaust streams (>200°C) is of

Data needs and challenges for quantum dot devices automation

Justyna Zwolak, Jacob Taylor, Reed Andrews, Jared Benson, Garnett Bryant, Donovan Buterakos, Anasua Chatterjee, Sankar Das Sarma, Mark Eriksson, Eliska Greplova, Michael Gullans, Fabian Hader, Tyler Kovach, Pranav S. Mundada, Mick Ramsey, Torbjoern Rasmussen, Brandon Severin, Anthony Sigillito, Brennan Undseth, Brian Weber
Gate-defined quantum dots are a promising candidate system for realizing scalable, coupled qubit systems and serving as a fundamental building block for quantum computers. However, present-day quantum dot devices suffer from imperfections that must be

Robustness of the projected squeezed state protocol

May 8, 2024
Author(s)
Byron Alexander, John J. Bollinger, Mark Tame
Projected squeezed (PS) states are multipartite entangled states generated by unitary spin squeezing, followed by a quantum measurement and post-selection. They lead to an appreciable decrease in the state preparation time of the maximally entangled N

Unbiased random bitstream generation using injection-locked spin-torque nano-oscillators

Comprehensive Quantum Calculation of the First Dielectric Virial Coefficient of Water

January 12, 2024
Author(s)
Giovanni Garberoglio, Chiara Lissoni, Luca Spagnoli, Allan H. Harvey
We present a complete calculation, fully accounting for quantum effects and for molecular flexibility, of the first dielectric virial coefficient of water and its isotopologues. The contribution of the electronic polarizability is computed from a state-of

Physical Component Libraries for SysPhS Modeling and Simulation in Manufacturing

October 10, 2023
Author(s)
Charles Manion, Conrad Bock, Raphael Barbau
Computer-interpretable representations of system structure and behavior are at the center of developing today's complex systems. Systems engineers create and review these representations using graphical languages and information models that capture

Understanding Stablecoin Technology and Related Security Considerations

September 5, 2023
Author(s)
Peter Mell, Dylan Yaga
Stablecoins are cryptocurrencies whose price is pegged to that of another asset (typically one with low price volatility). The market for stablecoins has grown tremendously – up to almost $200 billion USD in 2022. These coins are being used extensively in

Bearing area curve based partitioning for the verification of theoretical supplemental geometry on additively manufactured lattice structures

April 25, 2023
Author(s)
Maxwell R. Praniewicz, Jason Fox, Lucas Fournet-Fayard, Charles Cayron, Imade Koutiri, Anne-Francoise Obaton
The geometrical qualification of additively manufactured lattice structures has largely focused on the measurement of strut diameter, form variations, and surface texture. However, the exterior surfaces of the lattice structure, defined through theoretical

Development of a Diffusion Mobility Database for Co-based Superalloys

Greta Lindwall, Kil-Won Moon, Carelyn E. Campbell, Maureen E. Williams, Whitney Tso
To facilitate the development of high-temperature Co-based - superalloys, a Co-Ni based diffusion mobility database is developed for the eight component FCC (Face Centered Cubic) system of Co-Al-W-Ni-Cr-Ti-Ta-Re. A CALPHAD approach is used to represent

Grassmannian Shape Representations for Aerodynamic Applications

February 28, 2022

Olga Doronina, Zachary J. Grey, Andrew Glaws
Airfoil shape design is a classical problem in engineering and manufacturing. Our motivation is to combine principled physics-based considerations for the shape design problem with modern computational techniques informed by a data-driven approach

Analyzing 5G NR-U and WiGig Coexistence with Multiple-Beam Directional LBT

Yao Ma, Susanna Mosleh, Jason Coder
The mmWave radio frequency (RF) spectrum allocations provide a large bandwidth and an excellent dynamic spectrum sharing (DSS) opportunity for emerging 5G New-Radio unlicensed (NR-U) and Wireless Gigabit (WiGig) services. To support constructive DSS, we
