abstract = {Quasielastic 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. Every
scattering experiment leads to a dynamic structure factor
S(Q⃗ ,ω) or its spatial and temporal Fourier transform
(van Hove correlation function G(r⃗ ,t)). This shows
exactly where the atoms are and how they move. In this
manuscript the basics of the QENS method are presented and a
few examples highlighting the potentials of QENS are given:
(i) diffusion of liquids and gases in nano- and mesoporous
materials; (ii) hydrogen dynamics in a high temperature
polymer electrolyte fuel cell (HT-PEFC) and (iii) influence
of the surface interactions on polymer dynamics in
nanopores.},
