Hydration Water Freezing in Single Supported Lipid Bilayers

Figure 1

Sketch of a hydrated, single supported lipid bilayer, as suggested by [4–6]. Some of the hydration water molecules are drawn. The momentum transfer, 𝑄⃗, in the neutron scattering experiments was in the plane of the bilayers (𝑞_‖⃗) to detect in-plane motions of lipid and hydration water molecules. The experiment was sensitive to lipid diffusion, lipid acyl chain and hydration water dynamics.
