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

DIMENSIONAL METROLOGY IN DETERMINATION OF G WITH BIPM'S TORSION BALANCE

November 7, 2022
Author(s)
Vincent Lee, Stephan Schlamminger, Leon Chao, David B. Newell, Jon Pratt, Craig Shakarji, Clive Speake
This paper discusses the dimensional metrology challenges encountered while performing G measurements using the BIPM torsion balance and our solutions.

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

Compensation of Electrical Current Drift in Human-Robot Collision

November 5, 2022
Author(s)
Vinh Nguyen, Jennifer Case
Human-robot collaborative systems are being increasingly adopted in manufacturing environments due to their application flexibility, adaptability, and cost-effectiveness. These systems typically use electrical current sensors to measure joint torque in

ORGANIZATION OF SCIENTIFIC AREA COMMITTEES (OSAC) FOR FORENSIC SCIENCE

November 4, 2022
Author(s)
John Jones, Allison Getz, Donna J. Sirk
The National Institute of Standards and Technology (NIST) established the Organization of Scientific Area Committees (OSAC) for Forensic Science in 2014 to address a lack of discipline-specific forensic science standards. OSAC's mission is to strengthen

Evaluating Inter-Laboratory Comparison Data

November 3, 2022
Author(s)
Enrico Frahm, John D. Wright
The primary purpose of inter-laboratory comparisons is to demonstrate that the uncertainty specifications of the calibration measurement capabilities of the participating laboratories are correct. The most common criterion for assessing a participating

GRID-VIDEO MEASUREMENT METHOD FOR A-UGV'S SMALL OBSTACLE AVOIDANCE PERFORMANCE

November 3, 2022
Author(s)
Soocheol Yoon, Roger V. Bostelman, Ann Virts
With the advancement of factory logistics into the autonomous era comes the need to validate the safety and performance characteristics of Autonomous-Unmanned Ground Vehicles (A-UGVs) working in these application spaces ASTM Committee F45 has been

Quadrature Squeezing And Temperature Estimation From The Fock Distribution

November 3, 2022
Author(s)
Italo Pereira Bezerra, Hilma Vasconcelos, Scott Glancy
We present a method to estimate the amount of squeezing and temperature of a single-mode Gaussian harmonic oscillator state based on the weighted least squares estimator applied to measured Fock state populations. Squeezing and temperature, or equivalently

Aluminum Formate, Al(HCOO)3: An Earth-Abundant, Scalable, and Highly Selective Material for CO2 Capture

November 2, 2022
Author(s)
Hayden Evans, Dinesh Mullangi, Zeyu Deng, Yuxiang Wang, Shing B. Peh, Fengxia Wei, John Wang, Craig Brown, Dan Zhao, Pieremanuele Canepa, Anthony K. Cheetham
A combination of gas adsorption and gas breakthrough measurements show that the metal-organic framework, Al(HCOO) 3 (ALF), which can be made inexpensively from commodity chemicals, exhibits excellent CO 2 adsorption capacities and outstanding CO 2/N 2
