TLDR
Neutron diffraction experiments on selectively deuterated lipids provide a new method of determining to a segmental resolution the mean conformation of a lipid molecule as projected along the bilayer normal, despite the high amount of disorder that exists in these bilayers.About:

Structure of lipid bilayers
TL;DR: The uncertainty in structural results for lipid bilayers is being reduced and best current values are provided for bilayers of five lipids.

Molecular dynamics simulations of a fluid bilayer of dipalmitoylphosphatidylcholine at full hydration, constant pressure, and constant temperature.
TL;DR: Molecular dynamics simulations were performed on a system consisting of a bilayer of 64 molecules of the lipid dipalmitoylphosphatidylcholine and 23 water molecules per lipid to reproduce the correct density and to give a proper estimate of the area per lipid.

Physical properties of the fluid lipid-bilayer component of cell membranes: a perspective.
TL;DR: The motivation for this review arises from the conviction that, as a result of the mass of experimental data and observations collected in recent years, the study of the physical properties of membranes is now entering a new stage of development.

Deuterium magnetic resonance: theory and application to lipid membranes.
TL;DR: Proton and carbon-13 nmr spectra of unsonicated lipid bilayers and biological membranes are generally dominated by strong proton-proton and proton–carbon dipolar interactions and are rather difficult to analyse.

Nature of the Thermal pretransition of synthetic phospholipids: dimyristolyl- and dipalmitoyllecithin.
TL;DR: The hydrated synthetic lecithins, dimyristoyl and dipalmitoyllecithin, undergo two thermal transitions, a broad low enthalpy "pretransition" prior to the sharp first-order "chain-melting" transition and a structural transformation from a one-dimensional lamellar to a two-dimensional monoclinic lattice consisting of lipid lamellae distorted by a periodic ripple.
