Quasielastic Neutron Scattering Reveals Anisotropic Water Transport in Smectite Thin Film

Advanced Materials Interfaces
Clay minerals exhibit complex interactions with water that critically influence their functional properties, yet the anisotropic nature of water dynamics in smectite thin films remains underexplored.

Hydration‐ and Temperature‐Dependent Rotational Dynamics and Water Diffusion in Nanocellulose

Small Structures
Nanocellulose is a promising alternative to fossil‐derived materials, but its development is hindered by a limited understanding of cellulose–water interactions.

Comparison of time-of-flight and MIEZE neutron spectroscopy of H₂O. [PDF]

J Appl Crystallogr
We report a comparison of modulation of intensity with zero effort (MIEZE), a neutron spin–echo technique, and neutron time‐of‐flight spectroscopy, a conventional neutron scattering method. The basis of this comparison is provided by measurements performed on pure water under the same measurement conditions.We report a comparison of modulation of ...

Effect of Halide Variations on Cation Dynamics in MAPbX₃ (X = Cl, Br, and I). [PDF]

Small
This study uncovers the pivotal role of halide composition in dictating MA cation dynamics in MAPbX3 (X = Cl, Br, and I). MAPbCl3 exhibits the earliest and broadest onset of threefold MA rotation with the lowest activation energy, driven by pronounced octahedral distortions and reduced steric hindrance from the smaller Cl⁻ ion.

High Ionic Conduction in Rb- and Cs-Mixed Cation Amide for Energy Storage. [PDF]

Small
A mixed cation‐amide solid solution, Rb0.5Cs0.5NH2, based on the interaction between RbNH2‐ and CsNH2, has been developed. The Rb⁺/Cs⁺ cationic substitution leads to structural stabilization, resulting in high ionic conductivity in the Rb0.5Cs0.5NH2 compared to the single compounds.

Quasielastic neutron scattering in biology: Theory and applications [PDF]

Biochimica et Biophysica Acta (BBA) - General Subjects, 2017
Neutrons scatter quasielastically from stochastic, diffusive processes, such as overdamped vibrations, localized diffusion and transitions between energy minima. In biological systems, such as proteins and membranes, these relaxation processes are of considerable physical interest.

Scattering of the halo nucleus 11Be from a lead target at 3.5 times the Coulomb barrier energy

Physics Letters B, 2020
Angular distributions of quasielastic scattering and breakup of the neutron-rich halo nucleus 11Be on a 208Pb target at an incident energy of 140 MeV (about 3.5 times the Coulomb barrier) were measured at HIRFL-RIBLL.
