Neutron Interferometry Using a Single Modulated Phase Grating

April 1, 2023
Author(s)
Ivan Hidrovo, Joynoi Dey, Daniel Hussey, Nikolai Klimov, Leslie Butler, Kum Ham, W Newhauser
Neutron grating interferometry provides information on phase and small-angle scatter in addition to attenuation. Previously, phase grating moiré interferometers (PGMI) with two or three phase gratings have been developed. These phase-grating systems use

A Goldilocks Approach to Water Management: Amphiphilic Porous Transport Layers for Unitized Reversible Fuel Cells

Unitized reversible fuel cells (URFCs) are a promising option for both local and grid-scale energy storage, and could help facilitate the deployment of intermittent renewable power sources. URFCs consist of a single cell that operates in both fuel cell (FC

Thermal Polymorphism in CsCB11H12

Radovan Cerny, Matteo Brighi, Hui Wu, Wei Zhou, Mirjana Dimitrievska, Fabrizio Murgia, Valerio Gulino, Petra de Jongh, Benjamin Trump, Terrence J. Udovic
Thermal polymorphism in the alkali-metal salts incorporating the icosohedral monocarba-hydridoborate anion, CB11H12, results in intriguing dynamical properties leading to superionic conductivity for the lightest alkali-metal analogues, LiCB11H12 and

Nanoscale Bending Dynamics in Mixed-Chain Lipid Membranes

January 9, 2023
Author(s)
Elizabeth Kelley, Moritz Frewein, Orsolya Czakkel, Michihiro Nagao
Lipids that have two tails of different lengths are found throughout biomembranes in nature, yet the effects of this asymmetry on the membrane properties, are not well understood, especially when it comes to the membrane dynamics. Here we study the

Characterizing the ZrBe 2 H x Phase Diagram via Neutron Scattering Methods

January 1, 2023
Author(s)
Hui Wu, Wei Zhou, Terrence J. Udovic, Jr. Bowman, Bjorn C. Hauback
It is well-known that ZrBe 2H 1.5 exists as a single-phase hydride with hexagonal P6/mmm symmetry that undergoes some type of hydrogen sublattice ordering below 200 K (235-250 K for ZrBe 2D 1.5&). Both neutron powder diffraction and neutron vibrational

Simultaneous neutron and X-ray tomography for ex-situ 3D visualization of graphite anode degradation from extremely fast-charged lithium-ion batteries

November 16, 2022
Author(s)
Maha Yusuf, Jacob LaManna, Partha Paul, David Agyeman-Budu, Chuntian Cao, Alison Dunlop, Andrew Jansen, Bryant Polzin, Stephen Trask, Tanvir Tanim, Eric Dufek, Vivek Thampy, Hans-Georg Steinruck, Michael Toney, Johanna Weker
Extreme fast charging (XFC) of commercial lithium-ion batteries (LIBs) in ≤10-15 minutes will significantly advance the deployment of electric vehicles globally. However, XFC leads to considerable capacity fade, mainly due to graphite anode degradation

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
