Charge Density Wave Activated Excitons in MoSe2

January 5, 2022
Author(s)
Jaydeep Joshi, Benedikt Scharf, Igor Mazin, Sergiy Krylyuk, Daniel Campbell, Albert Davydov, Johnpierre Paglione, Igor Zutic, Patrick Vora
Layered materials enable the assembly of a new class of heterostructures where lattice-matching is no longer a requirement. Interfaces in these heterostructures therefore become a fertile ground for new physics as dissimilar phenomena can be coupled via

The Design and Performance of a Second-Generation Phi Meter

January 5, 2022
Author(s)
Ryan Falkenstein-Smith, Thomas Cleary
This report documents the design and performance of a second-generation phi meter used in multi-scale experimental applications. A constructed second-generation phi meter is implemented in bench and 2/5th scale experiments to demonstrate the instrument's

The Structure of Medium-Scale Pool Fires

January 5, 2022
Author(s)
Ryan Falkenstein-Smith, Kunhyuk Sung, Jian Chen, Kimberly Harris, Anthony Hamins
This report documents a series of time-averaged gas species measurements made along the centerline of methanol, ethanol, acetone, methane, and propane pool fires steadily burning in a quiescent environment. All gas species measurements are obtained using a

"The devil's in the detail": Release of an expanded, enhanced and dynamically revised forensic STR Sequence Guide

January 4, 2022
Author(s)
Christopher Phillips, Katherine Gettings, Jonathan King, David Ballard, Martin Bodner, Lisa Borsuk, Walther Parson
The STR sequence template file published in 2016 as part of the considerations from the DNA Commission of theInternational Society for Forensic Genetics on minimal STR sequence nomenclature requirements, has been comprehensively revised and audited using

A Spin Hamiltonian for BaCdVO(PO 4 ) 2

January 4, 2022
Author(s)
V. K. Bhartiya, S. Hayashida, K. Yu. Povarov, Z. Yan, Yiming Qiu, S. Raymond, A. Zheludev
Single crystal inelastic neutron scattering is used to study spin wave excitations in the fully polarized state of the frustrated quantum ferro-antiferromagnet BaCdVO(PO4) 2. The data analysis is based on a Heisenberg spin Hamiltonian that includes as many

AbsorbanceQ: An App for Generating Absorbance Images from Brightfield Images

January 4, 2022
Author(s)
Stephen Zimmerman, Carl Simon Jr., Greta Babakhanova
The AbsorbanceQ app converts brightfield microscope images into absorbance images that can be analyzed and compared across different operators, microscopes and time. Absorbance-based measurements are comparable, which is useful when the aim is to

Classification of STR allelic variation using massively parallel sequencing and assessment of flanking region power

January 4, 2022
Author(s)
Laurence Devesse, Lucinda Davenport, Lisa Borsuk, Katherine Gettings, Gabriella Mason-Buck, Peter Vallone, David Ballard
The application of massively parallel sequencing (MPS) to forensic genetics has led to improvements in multiple aspects of DNA analysis, however, additional complexities are concurrently associated with these advances. In relation to short tandem repeat

Demonstration that Einstein-Podolsky-Rosen Steering Requires More than One Bit of Faster-than-Light Information Transmission

January 4, 2022
Author(s)
Yu Xiang, Michael Mazurek, Joshua Bienfang, Michael Wayne, Carlos Abellan, Waldimar Amaya, Morgan Mitchell, Richard Mirin, Sae Woo Nam, Qiongyi He, Marty Stevens, Krister Shalm, Howard Wiseman
Schrödinger held that a local quantum system has some objectively real quantum state and no other (hidden) properties. He therefore took the Einstein-Podolsky-Rosen (EPR) phenomenon, which he generalized and called 'steering', to require nonlocal

DIC Challenge 2.0: Developing Images and Guidelines for Evaluating Accuracy and Resolution of 2D Analyses: Focus on the Metrological Efficiency Indicator

January 4, 2022
Author(s)
Philip Reu, EMC Jones, S.S. Fayad, B. Blaysat, E. Toussaint, Mark Iadicola, P. Lava, J Rethore, J. Yang, K. Bhattacharya, L. Yang, D. Deb, C.S.R. Vemulapati, M Klein, E Ando, E Roubin, O. Stamati, C Couture, Alexander Landauer, M. Liu, S Jaminion, T. Siebert, S.N. Olufsen
Background The DIC Challenge 2.0 follows on from the work accomplished in the first Digital Image Correlation (DIC) Challenge Reu et al. (Experimental Mechanics 58(7):1067, 1). The second challenge was required to better quantify the spatial resolution of

Late Stage Domain Coarsening Dynamics of Lamellar Block Copolymers

January 4, 2022
Author(s)
Jack F. Douglas, Maninderjeet Singh, Wenjie Wu, Vinay Nuka, Joseph Strzalka, Alamgir Karim
Block copolymer (BCP) phase separation is an intriguing phenomenon whose dynamics can be expected to differ significantly from that of the polymer blends due to constraint of chain connectivity that limits the ultimate scale of phase separation and the

Measurement of mass of aerosol particles

January 4, 2022
Author(s)
Kevin J. Coakley, Robert Hagwood, Kensei Ehara, Nobuhiko FUKUSHIMA, Kittichote WORACHOTEKAMJORN, Naoko TAJIMA, Hiromu SAKURAI
An aerosol particle mass analyzer (APM) which classifies aerosol particles according to their mass has been developed. Mass distributions of aerosol particles can be measured by the APM combined with a particle counting device. Particle mass that can be

Resource optimization of quantum-enabled channels using novel modulation schemes

January 4, 2022
Author(s)
Jabir Marakkarakath Vadakkepurayil, FNU Nur Fajar Rizqi Annafianto, Ivan Burenkov, Abdella Battou, Sergey Polyakov
We introduce new practical modulation schemes inspired by the quantum measurement. We experimentally show that our quantum-enabled communication system optimizes the combined resource efficiency (CRE) beyond the classical, shot-noise-limited CRE.

Role of low molecular weight polymers on the dynamics of silicon anodes during casting

January 4, 2022
Author(s)
Mary Burdette, Beth Armstrong, Ryan Murphy, Luke Heroux, Mathieu Doucet, Stephen Trask, Alexander Rogers, Gabriel Veith
This work probes the slurry architecture of a high silicon content electrode slurry with and without low molecular weight polymeric dispersants as a function of shear rate to mimic electrode casting conditions for poly(acrylic acid) (PAA) and lithium

The importance of international standards for the graphene community

Charles Clifford, Erlon H. Martins Ferreira, Toshiyuki Fujimoto, Jan Herrmann, Angela R. Hight Walker, Denis Koltsov, Christian Punckt, Lingling Ren, Gregory J. Smallwood, Andrew J. Pollard
If graphene and related 2D materials are to be used commercially, buyers need to have confidence in the measured properties of the material they obtain from suppliers. Scientists from international standards committees describe how the first joint ISO/IEC
