Wideband Cyclostationary Spectrum Analysis for Smart Factory Wireless Channels

July 5, 2023
Author(s)
Peter Vouras, Mohamed Hany, Rick Candell
Smart and highly automated factories rely on time sensitive networks (TSNs) to coordinate the actions of robots working together to complete a task. The dense layout of metallic objects on the factory floor creates a complex electromagnetic environment

Analyzing Cybersecurity Definitions for Non-experts

July 4, 2023
Author(s)
Lorenzo Neil, Julie Haney, Kerrianne Buchanan
There is no standard definition for cybersecurity, with current definitions often being technically-complex and targeted at practitioners and academics. However, non-experts (those who do not have security expertise) need an understandable definition to

H2 Generation by the 10B(n,alpha)7Li Reaction in High Temperature Water

July 4, 2023
Author(s)
Alan Keith Thompson, Mohamad Al-Sheikhly, Steven Guerin, David Bartels, Cameron Goodwin, Sangho Nam
H2 produced in water from the 10B(n,α)7Li fission reaction has been measured up to 300 oC. Thermal energy neutrons from the Rhode Island Nuclear Science Center's 2 MW reactor interact with boric acid-containing water in temperature-controlled high-pressure

Influence of Fluorescent Dopants on the Vat Photopolymerization of Acrylate-based Plastic Scintillators

July 3, 2023
Author(s)
Thomas Kolibaba, Jason Killgore, Caleb Chandler, Dominique Porcincula, Michael Ford, Benjamin Fein-Ashley, Jason Brodsky, Alan Sellinger
Plastic scintillators, a class of solid-state materials used for radiation detection, were additively manufactured with vat photopolymerization. The photopolymer resins consisted of a primary dopant and a secondary dopant dissolved in a bisphenol A

Quantum Disordered Ground State in the Triangular-Lattice Magnet NaRuO 2

July 1, 2023
Author(s)
Brenden R. Ortiz, Paul M. Sarte, Alon H. Avidor, Aurland Hay, Eric Kenney, Alexander I. Kolesnikov, Daniel M. Pajerowski, Adam A. Aczel, Keith M. Taddei, Craig Brown, Chennan Wang, Michael J. Graf, Ram Seshadri, Leon Balents, Stephen Wilson
The realization of spin liquid states born from the near-critical regime of the triangular lattice Hubbard model in inorganic materials remains a long-standing challenge, where weak spin-orbit coupling and other small perturbations often induce

Additive Manufacturing Data and Metadata Acquisition-General Practice

June 30, 2023
Author(s)
Yan Lu, Ho Yeung, Jason Fox, Felix Kim, Luke Mohr
Increasingly, a vast variety of additive manufacturing (AM) datasets are generated through AM development lifecycles. The amount, type, and speed of the collected data are unprecedented. The datasets are created and collected for material development

Additive Manufacturing Data Integration and Recommended Practice

June 30, 2023
Author(s)
Yan Lu, Milica Perisic, Albert T. Jones
Additive manufacturing (AM) creates parts layer by layer directly from three-dimensional computer-aided design data. Building in layers allows the fabrication of complex geometric shapes as well as functionally graded materials. Despite the part-quality

Effect of austenite fraction and stability on strength-hardening-ductility in additively manufactured 17-4 PH stainless steel containing nitrogen

June 30, 2023
Author(s)
Saadi Habib, Steven P. Mates, Fan Zhang, Mark R. Stoudt, James Zuback, Olaf Borkiewicz
Additively-manufactured (AM) 17-4 precipitation-hardening (PH) martensitic stainless steel (SS) built from nitrogen-atomized powder often retains a large volume fraction of austenite. The retained austenite lowers the yield strength compared to both

Standards as Enablers for a Circular Economy

June 30, 2023
Author(s)
KC Morris, Vincenzo Ferrero, Buddhika Hapuwatte, Noah Last, Nehika Mathur
A successful transition to a circular economy (CE) will require global participation, but the path to that transition will follow many unique routes depending on local situations. The transition must have rigorous technical underpinnings and well-conceived

Universal visible emitters in nanoscale integrated photonics

June 30, 2023
Author(s)
Gregory Spektor, David Carlson, Zachary Newman, Jinhie Lee Skarda, Neil Sapra, Logan Su, Sindhu Jammi, Andrew Ferdinand, Amit Agrawal, Jelena Vuckovic, Scott Papp
Visible wavelength lasers control quantum matter of atoms and molecules, enable frontiers of physical sensing, and are foundational for various applications. The development of visible integrated photonics opens the possibility for scalable circuits with

Microwave Characterization of Parylene C Dielectric and Barrier Properties

June 29, 2023
Author(s)
Nikolas Dale Barrera, Jacob Pawlik, Eugene Yoon, James Booth, Christian Long, Nathan Orloff, Ellis Meng, Angela Stelson
Parylene C thin films are commonly used as a passivation layer, protective coating, or substrate material in implantable medical devices. However, fluid or vapor may permeate through Parylene C films over time through defects, film edges, or bulk diffusion

Operando photoelectron spectromicroscopy of nanodevices: Correlating the surface chemistry and transport in SnO2 nanowire chemiresistors

June 29, 2023
Author(s)
Andrei Kolmakov, Trey Diulus, Kurt D. Benkstein, Stephen Semancik, Majid Kazemian, Matteo Amati, Maya Kiskinova, Luca Gregoratti
With size reduction of active elements in microelectronics to tens of nanometers and below, the effect of surface and interface properties on overall device performance becomes crucial. High resolution spectroscopic and imaging techniques provide a

Scaling the Projectile Perforation Resistance of Soft Materials

June 29, 2023
Author(s)
Katherine Evans, Shawn Chen, Amanda Souna, Stephan J. Stranick, Christopher Soles, Edwin P. Chan
From space dust to ballistic impact, controlling or mitigating a high velocity projectile impact event is a desirable outcome. The design and development of new and novel impact mitigating materials are greatly hindered by the use of macroscale projectile
