Adapting Modern Product Design to the Circular Economy

November 11, 2022
Author(s)
Vincenzo Ferrero, Buddhika Hapuwatte, KC Morris
The Circular Economy (CE) is an economic system that maximizes the time resources remain within the economy through re-circulation of materials. Transition to the CE, from a linear economy, is closely tied to information transfer between life cycle areas

Experimental realization of an extended Fermi-Hubbard model using a 2D lattice of dopant-based quantum dots

November 11, 2022
Author(s)
Richard M. Silver, Jonathan Wyrick, Xiqiao Wang, Ranjit Kashid, Garnett W. Bryant, Albert Rigosi, Pradeep Namboodiri, Ehsan Khatami
The Hubbard model is one of the primary models for understanding the essential many-body physics in condensed matter systems such as Mott insulators and cuprate high-Tc superconductors. Due to the long-range Coulomb interactions, accessible low

Flame spread and combustion dynamics in pine litter under unsteady wind conditions

November 11, 2022
Author(s)
Eric Mueller, Zakary Campbell-Lochrie, Carlos Walker-Ravena, Matt Patterson, Jason Cole, Michael Gallagher, Kenneth Clark, Nicholas Skowronski, Rory Hadden
Understanding flame spread and combustion dynamics in surface fuels is important for both planning and evaluating the impact of prescribed fires. However, prescribed fires tend to be conducted under light and unsteady wind conditions as compared with those

In-Process Data Integration for Laser Powder Bed Fusion Additive Manufacturing

November 11, 2022
Author(s)
Milica Perisic, Yan Lu, Albert T. Jones
Additive manufacturing (AM) is a powerful technology that can create complex metallic parts and has the potential to improve the economic bottom line for various industries. However, due to process instabilities, and the resulting material defects that

STEP-NC COMPLIANT DATA REPRESENTATIONS FOR POWDER BED FUSION IN ADDITIVE MANUFACTURING

November 11, 2022
Author(s)
Fahad Milaat, Paul Witherell, Martin Hardwick, Ho Yeung, Vincenzo Ferrero, Laetitia Monnier, Matthew Brown
Powder bed fusion (PBF) is an additive manufacturing (AM) technology that uses powerful beams to fuse powder material into layers of scanned patterns, thus producing parts with great geometric complexity. For PBF, process parameters, environmental control

Multivariate Zeolitic Imidazolate Frameworks with an Inverting Trend in Flexibility

November 10, 2022
Author(s)
Arijit Halder, Ryan Klein, C. McGuirk, Rachel Lively
Through systematic linker substitution in a flexible zeolitic imidazolate framework (ZIF) with step-shaped adsorption–desorption, structural intermediates between the known open and closed phases were isolated. Reflecting this, modulative sorption

Van der Waals SWCNT@BN Heterostructures Synthesized from Solution-Processed Chirality-Pure Single-Wall Carbon Nanotubes

November 10, 2022
Author(s)
Chiyu Zhang, Jacob Fortner, Peng Wang, Jeffrey Fagan, Shuhui Wang, Min Liu, Shigeo Maruyama, YuHuang Wang
Single-wall carbon nanotubes in boron nitride (SWCNT@BN) are one-dimensional van der Waals heterostructures that exhibit intriguing physical and chemical properties. As with their carbon nanotube counterparts, these heterostructures can form different

Dynamical Instability of 3d Stationary and Traveling Planar Dark Solitons

November 9, 2022
Author(s)
Ian Spielman, Amilson R. Fritsch, T. Mithun, Panayotis Kevrekidis
Here we revisit the topic of stationary and propagating solitonic excitations in self-repulsive three-dimensional Bose-Einstein condensates by quantitatively comparing theoretical analysis and associated numerical computations with our experimental results

An Overview of Ukrainian Thermophysics Research (1926 to 2022)

November 8, 2022
Author(s)
Vladimir Diky, Roman Zakusylo, Kostya Trachenko
We provide an overview of Ukrainian thermophysical research, its historical part and current state. The overview is supplemented by a database indexing thermophysical properties for molecular systems and alloys, as well as lists of scientific journals and

Intelligent-Fabric Computing: Challenges and Opportunities

November 8, 2022
Author(s)
Min Chen, Jia Liu, Pan Li, Hamid Gharavi, Yixue Hao, Jingyu Ouyang, Long Hu, Chong Hou, Iztok Humar, Lei Wei, Guang-Zhong Yang, Guangming Tao
With the advent of the Internet of Everything, people can easily interact with their environments immersively. The idea of pervasive computing is becoming a reality, but due to the inconvenience of carrying silicon-based entities and a lack of fine-grained

Introduction of nanoscale positive controls for nanotoxicology: A new aspect of utilization of stability-enhanced Gold-Polyethyleneimine conjugates (Au-PEIs)

November 8, 2022
Author(s)
Tae Joon Cho, Vincent A. Hackley, Vytas Reipa, Alessandro Tona, Christopher Sims, Natalia Farkas
Polyethyleneimine (PEI) conjugated gold nanoparticles (Au-PEIs) have potential use as positively charged gold nanoparticles (AuNPs) for nanomedical applications, due to their cationic surface that promotes cellular uptake and gene transfection. We report

Strain-life performance in hydrogen of DOT pressure vessel steel

November 7, 2022
Author(s)
May Ling Martin, Peter Bradley, Damian Lauria, Robert L. Amaro, Matthew Connolly, Andrew Slifka
Strain-life testing of a 4130 pressure vessel steel was conducted in air and in a high-pressure gaseous-hydrogen environment. Hydrogen causes an order of magnitude decrease in lifetime compared to in-air performance at the same strain-amplitudes. This

When Frodo Flips: End-to-End Key Recovery on FrodoKEM via Rowhammer

November 7, 2022
Author(s)
Michael Fahr Jr., Hunter Kippen, Andrew Kwong, Thinh Dang, Jacob Lichtinger, Dana Dachman-Soled, Daniel Genkin, Alexander Nelson, Ray Perlner, Arkady Yerukhimovich, Daniel Apon
In this work, we recover the private key material of the FrodoKEM key exchange mechanism as submitted to the NIST PQC standardization process. The new mechanism that allows for this is a Rowhammer-assisted poisoning of the FrodoKEM KeyGen process. That is
