Dynamics studied by Quasielastic Neutron Scattering (QENS) [PDF]

Adsorption, 2021
AbstractQuasielastic neutron scattering (QENS) allows measurement of the molecular displacements in time and space, from pico- to tens of nanoseconds and from Ångstroms to nanometers, respectively. The method probes dynamics from fast vibrational modes down to slow diffusive motion.

Dynamics of polymer electrolyte with LiTFSI via Quasi-Elastic Neutron Scattering [PDF]

EPJ Web of Conferences, 2023
Most lithium batteries offer a wide range of applications. However, safety issues are still an unresolved issue for several applications. To solve the safety issue of Li-ion batteries, solid polymer electrolyte is a promising candidate to replace ...

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.

Accessing self-diffusion on nanosecond time and nanometre length scales with minute kinetic resolution. [PDF]

J Appl Crystallogr
A new analysis framework to treat quasi‐elastic neutron spectroscopy data recorded at discrete energy transfers has been developed. This new approach can be employed successfully for kinetic studies of diffusive dynamics.Neutron spectroscopy uniquely and non‐destructively accesses diffusive dynamics in soft and biological matter, including for instance

Hydrogen Dynamics in Hydrated Chitosan by Quasi-Elastic Neutron Scattering

Bioengineering, 2022
Chitosan, an environmentally friendly and highly bio-producible material, is a potential proton-conducting electrolyte for use in fuel cells. Thus, to microscopically elucidate proton transport in hydrated chitosan, we employed the quasi-elastic neutron ...

Soft Phonon Mode Triggering Fast Ag Diffusion in Superionic Argyrodite Ag8GeSe6

Small, Volume 19, Issue 49, December 6, 2023., 2023
Innelastic neutron scattering and Ab‐initio molecular dynamics simulations are employed to unravel that phonon softening on heating to Tc ≈ 350 K triggers fast Ag diffusion in the canonical superionic Argyrodite Ag8GeSe6, which illustrates the microscopic interconnection between soft phonons and mobile ions in superionic materials.
