    "abstract": "Lipid membranes in a physiological context cannot be understood without\ntaking into account their mobile environment. Here, we report on a high\nenergy-resolution neutron backscattering study to investigate slow motions on\nnanosecond time scales in highly oriented solid supported phospholipid bilayers\nof the model system DMPC -d54 (deuterated\n1,2-dimyristoyl-sn-glycero-3-phoshatidylcholine). This technique allows\ndiscriminating the Q-dependent onset of mobility and provides a benchmark test\nregarding the feasibility of dynamical neutron scattering investigations on\nthese sample systems. Apart from freezing of the lipid acyl-chains, we could\nobserve a second freezing temperature that we attribute to the hydration water\nin between the membrane stacks. The freezing is lowered several degrees as\ncompared to (heavy) bulk water.",
