abstract = {In this manuscript, we are investigating the contribution
of dynamic membrane properties of phospholipid membranes to
coherent scattering signals under grazing incidence.
Spectroscopic measurements under grazing incidence can
provide useful insight into the properties of biological
membranes; however, they are often impeded by weak signals.
By using grazing-incidence small-angle neutron scattering
(GISANS) to identify a dynamic scattering contribution, we
are able to independently corroborate the existence of a
previously found dynamic mode, now measured by
grazing-incidence neutron spin echo spectroscopy (GINSES).
Additionally, by increasing the speed of measurement
compared to GINSES from several days to hours, we were able
to explore the temperature behavior of this mode in
phospholipid membranes. These dynamic modes of the membranes
show a wavelength of around 700 Å in-plane of the membrane
and are most pronounced around 37 ∘C and strongly decrease
at lower temperatures below 25 ∘C before vanishing at 20
∘C. We therefore speculate that they may be linked to
biologically relevant functions of the membranes themselves.
To our knowledge, this is the first report of an
investigation of that membrane mode by means of GISANS.},
