Alcohol Interactions with Lipid Bilayers [PDF]
We investigate the structural changes to lipid membrane that ensue from the addition of aliphatic alcohols with various alkyl tail lengths. Small angle neutron diffraction from flat lipid bilayers that are hydrated through water vapor has been employed ...

Structure of lipid bilayers [PDF]
The quantitative experimental uncertainty in the structure of fully hydrated, biologically relevant, fluid (L(alpha)) phase lipid bilayers has been too large to provide a firm base for applications or for comparison with simulations. Many structural methods are reviewed including modern liquid crystallography of lipid bilayers that deals with the fully

A criterion to identify the equilibration time in lipid bilayer simulations [PDF]
With the aim of establishing a criterion for identifying when a lipid bilayer has reached steady state using the molecular dynamics simulation technique, lipid bilayers of different composition in their liquid crystalline phase were simulated in aqueous ...

Structure determination of lipid bilayers
A method of determining the phases of X-ray reflections from oriented model membrane systems at low resolution is described. The method involves deconvolution and requires that d less than or equal to 2v where v is the width of the head group region within the bilayer and d is the thickness of the bilayer.

The Effects of Splayed Lipid Molecules on Lubrication by Lipid Bilayers [PDF]
The outstanding lubrication of articular cartilage in the major synovial joints such as hips and knees, essential for the joint well-being, has been attributed to boundary layers of lipids at the outer cartilage surfaces, which have very low friction ...

Fluctuations, inherent in flexible and biologically relevant lipid bilayers, make quantitative structure determination challenging. Shortcomings in older methods of structure determination have been realized and new methodologies have been introduced that take fluctuations into account.

Effect of CM15 on Supported Lipid Bilayer Probed by Atomic Force Microscopy
Antimicrobial peptides are key components of the immune system. These peptides affect the membrane in various ways; some form nano-sized pores, while others only produce minor defects.

Correlated diffusion in lipid bilayers [PDF]
SignificanceDynamic processes on membrane surfaces are essential for biological function. Traditionally, quantitative measurements of lipid/protein motion have been interpreted in the framework of membrane hydrodynamics. However, some recent single-molecule tracking studies have proven difficult to interpret via hydrodynamic arguments.
