Non-magnetic ion site disorder effects on the quantum magnetism of a spin-1/2 equilateral triangular lattice antiferromagnet

March 10, 2022
Author(s)
Qing Huang, R. Rawl, W. W. Xie, E. S. Chou, V. S. Zapf, X. X. Ding, C. Mauws, C. R. Wiebe, E. X. Feng, H. B. Cao, W. Tian, J. Ma, Yiming Qiu, Nicholas Butch, H. D. Zhou
With the motivation to study how non-magnetic ion site disorder affects the quantum magnetism of Ba3CoSb2O9, a spin-1/2 equilateral triangular lattice antiferromagnet, we performed DC and AC susceptibility, specific heat, elastic and inelastic neutron

Shengqing Xiao, Dimitri Nefodov, Mark O. McLinden, Markus Richter, Thorsten Urbaneck
In the context of the global energy transition, solar energy holds a promising potential as an energy source for a sustainable heat supply. Solar thermal collector in combination with heat pump technology utilizing electricity from renewable sources, such

A Tool to Model Virus Particle Exposure in Residences (ViPER)

March 9, 2022
Author(s)
Stephen Zimmerman, Brian Polidoro, Lisa Ng, William Stuart Dols, Steven Emmerich
Virus Particle Exposure in Residences (ViPER) is a web-based, single zone indoor air quality and ventilation analysis tool developed by the National Institute of Standards and Technology (NIST) for evaluating an occupant's relative exposure to virus-laden

Atomic Physics and Spectroscopy During the First 50 Years of JPCRD

March 9, 2022
Author(s)
Yuri Ralchenko
Atomic spectroscopy and atomic physics papers represent a significant part of publications in Journal of Physical and Chemical Reference Data (JPCRD). Critically compilations of spectroscopic data, accurate calculations of collisional parameters

New International Formulation for the Thermal Conductivity of Heavy Water

March 9, 2022
Author(s)
Marcia L. Huber, Richard A. Perkins, Marc Assael, Stella Monogenidou, Robert Hellmann, Jan Sengers
The International Association for the Properties of Water and Steam (IAPWS) has adopted a new formulation for the thermodynamic properties of heavy water. This manuscript describes the development of a new correlation for the thermal conductivity of heavy

Versailles Project on Advanced Materials and Standards (VAMAS) Interlaboratory Study on Measuring the Number Concentration of colloidal gold nanoparticles

March 9, 2022
Author(s)
Caterina Minelli, Karen E. Murphy, Monique Johnson, Antonio Montoro Bustos, Jeffrey Fagan, Ingo Strenge
We describe the outcome of an international interlaboratory study of the measurement of particle number concentration of colloidal nanoparticles, project 10 of the technical working area 34, "Nanoparticle Populations" of the Versailles Project on Advanced

ZKASP: ZKP-based Attestation of Software Possession for Measuring Instruments

March 9, 2022
Author(s)
Luis Brandao, Carlos Eduardo Cardoso Galhardo, Rene Peralta
Software-controlled measuring instruments used in commercial transactions, such as fuel dispensers and smart meters, are sometimes subject to "memory replacement" attacks. Cybercriminals replace the approved software by a malicious one that then tampers

A Kinetic Mechanism for CF3I Inhibition of Methane-Air Flames

March 8, 2022
Author(s)
Valeri I. Babushok, Donald R. Burgess Jr., Gregory T. Linteris
The influence of CF3I on the burning velocity of methane–air flame is experimentally and numerically studied. Experimental results demonstrate that the inhibition effectiveness of CF3I is very close to that of CF3Br. A detailed kinetic model of flame

Nanoscale Photoexcited Carrier Dynamics in Perovskites

March 8, 2022
Author(s)
Samuel Berweger, Fei Zhang, Bryon Larson, Andrew Ferguson, Axel Palmstrom, Obadiah Reid, Thomas Mitchell (Mitch) Wallis, Kai Zhu, Joseph Berry, Pavel Kabos, Sanjini Nanayakkara
The excellent optoelectronic properties of lead-halide perovskite thin films are complemented by their tolerance to broad compositional variations and associated strain, which allows tuning of desired properties such as the optical bandgap. On the other

Strong coupling between a topological insulator and a III-V heterostructure at terahertz frequency

March 8, 2022
Author(s)
Garnett W. Bryant, D. Quang To, Zhengtianye Wang, Q. Dai Ho, Ruiqi Hu, Wilder Acuna, Yongchen Liu, Anderson Janotti, Joshua Zide, Stephanie Law, Matthew Doty
We probe theoretically the emergence of strong coupling in a system consisting of a topological insulator (TI) and a III-V heterostructure using a numerical approach based on the scattering matrix formalism. Speci cally, we investigate the interactions

A Peg-in-Hole Test and Analysis Method for Exoskeleton Evaluation

March 7, 2022
Author(s)
Ann Virts, Roger V. Bostelman, Soocheol Yoon, Ya-Shian Li-Baboud, Mili Shah
Work-place MusculoSkeletal Disorders (WMSD) continue to be the most significant source of industrial work force injuries. Exoskeletons are emerging as personal protective equipment (PPE) for sustained, repetitive, or intensive industrial tasks. This

Color-Temperature Dependence of Indoor Organic Photovoltaic Performance

March 5, 2022
Author(s)
Boya Zhang, Justin Bonner, Lakshmi Murthy, Thien Nguyen, Fong-Yi Cao, Yen-Ju Cheng, Behrang Hamadani, Julia Hsu
Organic materials are uniquely suited for indoor light energy harvesting because they absorb mostly in the visible spectrum and the absence of ultraviolet light minimizes their degradation. However, the performance of photovoltaic devices under indoor

Chapter: Structure and phase behavior of polyampholytes and polyzwitterions

March 4, 2022
Author(s)
Phillip Pickett, Yuanchi Ma, Vivek Prabhu, Michael Lueckheide, Nicholas Posey
Polyelectrolytes contain many units of charged moieties, often as either anionic or cationic. However, when a polymer comprises both anionic and cationic monomers, the result is a polyampholyte. Polyzwitterions are a type of polyampholyte that contain
