Thermodynamics and kinetics of the early steps of solid-state nucleation in the fluid lipid bilayer

Article Abstract:

Temperature-scanning (10-70 degree C) calorimetric, densitometric, and acoustic measurements are performed in aqueous dispersions of dipalmitoylphosphatidylcholine multilamellar vesicles. The measured quantities display anomalous deviations from the 'ideal' shape of their temperature dependence curves to the early steps of gel-state nucleation, in the biologically relevant liquid-crystalline state close to the chain freezing point (within 42-50 degree C, in this case).

Evidence of domain formation in cardiolipin-glycerophospholipid mixed monolayers: A thermodynamic and AFM study

Article Abstract:

The thermodynamic behavior of mixed monolayers of cardiolipin-dipalmitoylphosphatidylcholine (CLP-DPPC) and cardiolipin-dipalmitoylphosphatidylethanolamine (CLP-DPPE) is investigated by studying their Langmuir surface pressure and surface potential isotherms at different cardiolipin molar fractions. The overall thermodynamic behavior is independent of mole fraction for the mixed CLP-DPPC monolayers while a critical fraction exists for the CLP-DPPE monolayers.

A molecular dynamics simulation study of [C.sub.60] fullerenes inside a dimyristoylphosphatidylcholine lipid bilayer

Article Abstract:

The atomistic molecular dynamics simulations of [C.sub.60] inside a dimyristoylphosphatidylcholine lipid bilayer and an alkaline melt fullerene can undergo strong dispersion when placed at about 6-7 Angstrom off the center plane. The interactions between fullerenes measured as potential of mean force (POMF) studies show that the larger fullerene aggregates are difficult to accommodate in the bilayer.
