2006 journal article

Formation of a ripple phase in nanotubular dimyristoylphosphatidylcholine Bilayers confined inside nanoporous aluminum oxide substrates observed by DSC

LANGMUIR, 22(13), 5563–5565.

By: A. Alaouie n & A. Smirnov  n

Contributors: A. Alaouie n & A. Smirnov n 

MeSH headings : Aluminum Oxide; Calorimetry, Differential Scanning; Dimyristoylphosphatidylcholine / chemistry; Electrochemistry; Electron Spin Resonance Spectroscopy; Lipid Bilayers / chemistry; Nanotubes / chemistry; Thermodynamics
TL;DR: The pretransition indicates that nanotubular bilayers could exist in a ripple phase, whereas hysteresis points to a similarity in the phase transition mechanisms. (via Semantic Scholar)

2006 journal article

Ultra-stable temperature control in EPR experiments: Thermodynamics of gel-to-liquid phase transition in spin-labeled phospholipid bilayers and bilayer perturbations by spin labels

JOURNAL OF MAGNETIC RESONANCE, 182(2), 229–238.

By: A. Alaouie n & A. Smirnov  n

Contributors: A. Alaouie n & A. Smirnov n 

author keywords: lipid bilayer; phase transition; variable temperature accessory; cooperativity
MeSH headings : Electron Spin Resonance Spectroscopy / instrumentation; Equipment Design; Lipid Bilayers / chemistry; Phospholipids / chemistry; Spin Labels; Temperature
TL;DR: The data provide DSC and EPR evidence that in studies of the gel-to-liquid phase transition, the effect of bilayer perturbation by spin-labeled lipids is negligible and therefore thermodynamic parameters of the phase transition can be accurately measured byspin-labeling EPR.

2005 journal article

Cooperativity and kinetics of phase transitions in nanopore-confined bilayers studied by differential scanning calorimetry

BIOPHYSICAL JOURNAL, 88(2), L11–L13.

By: A. Alaouie n & A. Smirnov n 

Contributors: A. Alaouie n & A. Smirnov n 

MeSH headings : Calorimetry, Differential Scanning / methods; Computer Simulation; Dimyristoylphosphatidylcholine / analysis; Dimyristoylphosphatidylcholine / chemistry; Kinetics; Lipid Bilayers / analysis; Lipid Bilayers / chemistry; Liposomes / chemistry; Models, Chemical; Molecular Conformation; Nanostructures / analysis; Nanostructures / chemistry; Nanostructures / ultrastructure; Phase Transition; Porosity; Surface Properties; Temperature
TL;DR: This analysis shows that although confinement of bilayers to the nanopores of approximately 177 nm in diameter results in a more than threefold longer characteristic time of the lipid rearrangement and a decrease in the cooperative unit number, the phase transition temperature is unaffected.
