August 22, 2024
Author(s)
Jenny Wu, Pan-Yu Hou, Stephen Erickson, Adam Brandt, Yong Wan, Giorgio Zarantonello, Daniel Cole, Andrew C. Wilson, Daniel Slichter, Dietrich Leibfried
Cooling of atomic motion is a crucial tool for many branches of atomic physics, ranging from fundamental physics explorations to quantum information and sensing. For trapped ions, electromagnetically-induced-transparency (EIT) cooling has received

Latency-Sensitive Networked Control Using 802.11ax OFDMA Triggering

August 22, 2024
Author(s)
Karl Montgomery, Mohamed Hany, Rick Candell
Orthogonal Frequency-Division Multiple Access (OFDMA) is a feature implemented in IEEE 802.11ax (Wi-Fi 6) that aims to improve performance by sending packets simultaneously to multiple users. This paper highlights performance issues when using OFDMA with a

Towards Sustainable Electronics: Exploring IC Reuse for Circular Economy Transformation

August 22, 2024
Author(s)
Nowell Stoddard, Lisa Paterson, Mark Schaffer, Tom Etheridge, Nehika Mathur, KC Morris, Lise Laurin, Amos Ncube
This perspective paper addresses the importance of responsible end of life (EOL) management of integrated circuits (ICs or chips), with a particular focus on the possibility of IC reuse as an avenue to address the high impacts of chip manufacturing and the

5G NR and LTE Downlink Coexistence Measurements Using Software-Defined Radios

August 20, 2024
Author(s)
Nadia Yoza Mitsuishi, Yao Ma, Jason Coder
With the rapid deployment of 5G New Radio (NR) in the sub-6 GHz frequency bands, cellular operators need to accommodate this new technology within the limited spectrum licensed to them, mostly occupied by 4G Long-Term Evolution (LTE). This poses the

Community Resilience Economic Decision Guide and Tool: Research Overview

August 20, 2024
Author(s)
Christina Gore, Jennifer Helgeson
Community resilience planning often requires quantifying and understanding the trade-offs that communities make between the benefits and costs of different resilience actions. The Economic Decision Guide walks communities through the steps to evaluate

A Standards-Guided Approach for Formalizing Product Circularity Assessment Metrics

August 19, 2024
Author(s)
Junwon Ko, Sandwana Sneethan, Gisele Bortolaz Guedes, Fazleena Badurdeen, I.S. Jawahir, Buddhika Hapuwatte, KC Morris
The industrial transition towards a more sustainable Circular Economy (CE) emphasizes the need for products that align with CE principles and robust methods for assessing their circularity performance. However, ambiguities between metrics vs. indicators

Maximally efficient exchange in thin flow cells using density gradients

August 19, 2024
Author(s)
Megan Mitchell, Charles Majkrzak, David Hoogerheide
Flow cells are ubiquitous in laboratories and automated instrumentation and are crucial for ease of sample preparation, analyte addition, and buffer exchange. Often, the assumption that the fluids have exchanged completely in a flow cell is crucial to data

Model for the Viscosity and Thermal Conductivity of Tetrahydrofuran

August 17, 2024
Author(s)
Sofia Sotiriadou, Eleftheria Ntonti, Marc Assael, Konstantinos Antoniadis, Marcia L. Huber
We present a hybrid predictive-correlative engineering model for the calculation of the viscosity and thermal conductivity of tetrahydrofuran (THF) in the fluid phase. It incorporates critically evaluated experimental data where available, and predictive

Driving U.S. Innovation in Materials and Manufacturing using AI and Autonomous Labs

August 14, 2024
Author(s)
Howie Joress, Zachary Trautt, Austin McDannald, Brian DeCost, A. Gilad Kusne, Francesca Tavazza
With the goal of advancing US competitiveness and excellence in the materials and manufacturing industries, we present our vision for the National Center for Autonomous Materials Science. The objective of this center is to enable and promote the use of

Separation of microplastics from deep-sea sediment using an affordable, simple to use, and easily accessible density separation device

August 14, 2024
Author(s)
Katherine Shaw, Rachel Sandquist, Cameron Fairclough, Jesse Black, Alex Fitzgerald, Scott Gallager, Jennifer Lynch
Microplastics accumulate in the environment but methods to extract particles from sediment for quantification and identification often lack accuracy and reproducibility. Existing methods vary greatly and many do not achieve adequate microplastic separation

Zero-temperature entanglement membranes in quantum circuits

August 13, 2024
Author(s)
Grace Sommers, Sarang Gopalakrishnan, Michael Gullans, David Huse
In chaotic quantum systems, the entanglement of a region A can be described in terms of the surface tension of a spacetime membrane pinned to the boundary of A. Here, we interpret the tension of this "entanglement membrane" in terms of the rate at which

The Block Copolymer Phase Behavior Database

August 10, 2024
Author(s)
Nathan Rebello, Akash Arora, Hidenobu Mochigase, Tzyy-Shyang Lin, Debra Audus, Bradley Olsen
The Block Copolymer Database (BCDB) is a platform that allows users to search, submit, visualize, benchmark, and download experimental phase measurements and their associated characterization information for di- and multiblock copolymers. To the best of

Coexistence Testing: Comparing Conducted and Radiated Test Results

August 9, 2024
Author(s)
Susanna Mosleh, Nadia Yoza Mitsuishi, Jason Coder, Carl Sunderman
In an era of ubiquitous wireless devices, ensuring their coexistence in shared electromagnetic environments has become increasingly critical. This paper explores the dynamics of coexistence testing and compares two coexistence test environments outlined in

A Review of Community Resilience Indicators Using a Systems Measurement Framework
