QENS and quasielastic Mössbauer spectroscopy for studying diffusion

Physica B: Condensed Matter, 1996
QENS and quasielastic Mossbauer spectroscopy (QMS) are closely related in that both measure the double Fourier transform S(Q, ω) of the self-correlation function, which they deduce from scattering (QENS) and from resonant emission or absorption of nuclear γ radiation (QMS).

Water dynamics in Na zeolite P by QENS

Physica B: Condensed Matter, 1997
Abstract Quasi-elastic neutron-scattering (QENS) measurements have been made using the IRIS spectrometer (ISIS, UK) on water in synthetic Na zeolite P. The quasi-elastic broadening observed is assigned to a rotation of the water molecules.

Diffusive dynamics in trehalose aqueous solutions by QENS

Physica B: Condensed Matter, 2000
Abstract The work reports preliminary QENS results on aqueous solutions of trehalose. The employment of H/D substitution allows the separation of the diffusive dynamics of water from that of trehalose. The data analysis shows a slowed down water dynamics in comparison to that of bulk water.

QENS and NMR Study of Water Dynamics in SBA-15 with a Low Water Content [PDF]

, 2015
In this study, motions performed by water molecules adsorbed on the silica surface of SBA-15 material with 6.1% of water content (15% of pore filling) were investigated using NMR and Quasielastic Neutron Scattering (QENS) techniques.

Diffusion of acetylene embedded in Na–Y zeolite: QENS and MD simulation studies [PDF]

Physica B: Condensed Matter, 2006
We report here the studies of the dynamics of acetylene molecules adsorbed in Na–Y zeolite cages using Quasielastic neutron scattering (QENS) and molecular dynamics (MD) simulation techniques.

A Co(ii)-coordination polymer for ultrahigh superprotonic conduction: an atomistic insight through molecular simulations and QENS experiments

, 2020
Proton conducting materials are key components in proton exchange membrane fuel cells for clean energy research. Most such conducting crystalline materials (MOFs/CPs/COFs/HOFs) show limited practical application due to the multistep synthesis of organic ...

QENS investigation of the dynamics of starch saccharides

Physical Chemistry Chemical Physics, 2005
We present here quasi-elastic neutron scattering results on D20 hydrated samples of amylose, one of the main saccharide components of starch. Two different sample hydrations (h = 0.5 and 1.0 g D2O (g dry amylose)-1 have been investigated in the temperature range 170 to 350 K.
