Hydration- and Temperature-Dependent Rotational Dynamics and Water Diffusion in Nanocellulose
Nanocellulose is a promising alternative to fossil-derived materials, but its development is hindered by a limited understanding of cellulose–water interactions. Herein, quasielastic neutron scattering (QENS) is used to investigate how hydration and temperature affect the localized rotations in cellulose nanocrystals (CNC) and the diffusion of mobile water. QENS reveals ...
Bright Monocompound Metal Halide Scintillator for Fast Neutron Radiography
Fast neutron imaging is a promising technique for visualizing objects containing dense, mixed light-and-heavy-elements materials, such as combustion engines, nuclear fuel assemblies, and fossils, where X-rays and thermal neutrons are ineffectiv. However, the limited efficiency of current detection technologies hinders their widespread adoption. Recoil proton detection ...
A New Quantum Landscape: Coexisting High-Tc Superconductivity, Magnetism, and Complex Charge Order in LaRu3Si2.
Despite intense research on kagome superconductors, many fundamental questions remain—especially regarding the unconventional nature of their charge order and superconducting phases. These materials are rich in complexity, and to truly unravel their behavior, a broad and integrated approach is essential. In our study ...
Microscopic Origin of Reduced Magnetic Order in a Frustrated Metal
Although magnetic frustration in metals provides a promising avenue for novel quantum phenomena, their microscopic interpretation is often challenging. Here, we use the face-centered cubic intermetallic HoInCu4 as model material to show that Hamiltonians neglecting the charge degree of freedom are appropriate for frustrated metals possessing low density of states at the Fermi surface ...
Understanding and Addressing the Performance Asymmetry Issue in Semitransparent Laminated Organic Photovoltaic Devices
Organic photovoltaics (OPVs) offer a promising solution for indoor energy harvesting. However, fundamental investigations to understand and optimize industrial processes such as roll-to-roll lamination for upscaling remain limited. This study investigates a critical failure mode in the upscaling of OPVs.
One major challenge ...
Absence of Altermagnetic Magnon Band Splitting in MnF2
Altermagnets are collinear compensated magnets in which the magnetic sublattices are related by rotation rather than translation or inversion. One of the quintessential properties of altermagnets is the presence of split chiral magnon modes. Recently, such modes have been predicted in MnF2.
Here, we report inelastic neutron scattering results ...
