Quasielastic neutron scattering experiment on water using TOFLAR (Time Of Flight and LARmor precession) technique at SNS

EPJ Web of Conferences, 2015
We present the results of the first TOFLAR (Time Of Flight and LARmor precession) experiment with a Larmor modulation device positioned after the sample. Using a setup based on the configuration of the SNS-NSE spectrometer (Spallation Neutron Source, USA)

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.

A note on quasielastic neutron scattering

Journal de Physique I, 1994
We present a theorem that in coherent quasielastic neutron scattering on a confined and limited system of identical particles only the configuration-configuration correlations have to be examined without any hindsight on the distribution of the particles inside the configuration.

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.

Correlated Polymer-Proton Hopping Enables Water-Independent Fast Proton Transport in Poly(Ionic Liquid) Membranes. [PDF]

Adv Sci (Weinh)
A polymer chain in motion: backbone, ring, and counterion dynamics interlock across timescales to relay protons through poly(ionic liquid) membranes. ABSTRACT Polymer electrolyte membranes composed of ionic liquids (IL), capable of conducting protons efficiently at elevated temperatures, without external humidification, could transform fuel cell ...

Halide Perovskite: A Rich Source of Thermal Insulator. [PDF]

Adv Sci (Weinh)
Halide perovskites exhibit ultralow thermal conductivity driven by intrinsic lattice softness and strong anharmonicity, falling below conventional defect‐engineering limits. Weak metavalent bonding, A‐site rattling, and dynamic octahedral tilting drive phonon scattering to the Ioffe–Regel limit, where wave‐like tunneling replaces particle‐like ...
