Resonant X-ray Scattering in Polymer Science

April 1, 2022
Author(s)
Brian Collins, Eliot Gann
Resonant Soft X-ray Scattering (RSoXS) is an emerging, powerful technique to probe the nano-to-mesoscale ordering of polymers and other molecules. It joins together small-angle X-ray scattering (a statistical nanoprobe) with X-ray spectroscopy that brings

The Very Small-Angle Neutron Scattering Instrument at the National Institute of Standards and Technology

April 1, 2022
Author(s)
John Barker, James Moyer, Steven Kline, G. Jensen, Jeremy Cook, Cedric Gagnon, Elizabeth Kelley, Jean Philippe Chabot, Nicholas C. Maliszewskyj, Chirag Parikh, Wangchun Chen, Ryan Murphy, C. Glinka
A description and the performance of the Very Small-Angle Neutron Scattering (VSANS) Diffractometer at the National Institute of Standards and Technology are presented. The measurement range of the instrument extends over three decades of momentum transfer

Reassessing the Significance of Reduced Aggregation and Crystallinity of Naphthalene Diimide-Based Copolymer Acceptors in All-Polymer Solar Cells

March 28, 2022
Author(s)
Eliot Gann, Christopher McNeill, Doan Vu, Martyn Jervic, Chao Wang, Lars Thomsen, Mats Andersson
Terpolymerization is a facile and effective strategy to control the aggregation and crystallinity of semiconducting polymers which has been exploited to improve the photovoltaic performance of all-polymer solar cells (all-PSCs). Applying this strategy to

Disinfection of Respirators with Ultraviolet Radiation

March 25, 2022
Author(s)
Dianne L. Poster, Matthew Hardwick, C Cameron Miller, Michael A. Riley, W. W. Shanaka I. Rodrigo, Andras E. Vladar, John D. Wright, Christopher D. Zangmeister, Clarence Zarobila, Jeremy Starkweather, John Wynne, Jason Yilzarde
Data for interpreting virus inactivation on N95 face filtering respirators (FFRs) by ultraviolet (UV) radiation are important in developing UV strategies for N95 FFR disinfection and reuse for any situation, whether it be everyday practices, contingency

Recent Advances in Weyl Semimetal ( MnBi2Se4) and Axion Insulator (MnBi2Te4)

March 25, 2022
Author(s)
Sugata Chowdhury, Kevin Garrity, Francesca Tavazza
Extensive research is currently focused on 2D and 3D magnetic topological insulators (MTIs), as their many novel properties make them excellent candidates for applications in spintronics and quantum computing. Practical MTIs requires a combination of

Understanding Signatures of Emergent Magnetism in Topological Insulator/Ferrite Bilayers

March 24, 2022
Author(s)
Lauren J. Riddiford, Alexander Grutter, Timothy Pillsbury, Max Stanley, Danielle Reifsnyder Hickey, Peng Li, Nasim Alem, Nitin Samarth, Yuri Suzuki
Magnetic insulator and topological insulator heterostructures have been studied in search of induced magnetism in the topological insulator, but chiral edge states have been elusive. We have identified MgAl 0.5Fe 1.5O 4/Bi 2Se 3 bilayers for a possible

Influence of Dimensionality on the Charge Density Wave Phase of 2H-TaSe2

March 23, 2022
Author(s)
Sugata Chowdhury, Albert Rigosi, Heather Hill, David B. Newell, Angela R. Hight Walker, Francesca Tavazza, Andrew Briggs
Metallic transition metal dichalcogenides like tantalum diselenide (TaSe2) exhibit exciting behaviors at low temperatures including the emergence of charge density wave (CDW) states. In this work, density functional theory (DFT) is used to classify the
