Incoherent quasielastic neutron scattering study on the polymorphism of tristearin: Dynamical properties of hydrocarbon chains

Article Abstract:

Incoherent quasielastic neutron scattering (IQNS) is used for studying the dynamic properties of acyl chains in the three polymorphic phases [alpha], [beta]' and [beta] of tristearin [(C.sub.3][H.sub.5][(OCO[C.sub.17][H.sub.35]).sub.3]]. The studies have shown that the dynamics of acyl chains have depended on their lateral packing and temperature, featuring the characteristics of the [alpha] phase whose acyl chains are most mobile.

Coexistence and mutual competition of vesicles with different size distributions

Article Abstract:

The mutual interaction of vesicles in three different systems is investigated, that is, POPC vesicles with POPC vesicles, oleic acid vesicles with oleic acid vesicles and POPC vesicles with oleic acid vesicles. The different size populations of vesicles can coexist in the same solution without tendency to fuse with each to search for an energy minimum.

Solid-state(super 13)C NMR study on order --> disorder phase transition in oleic acid

Article Abstract:

The reversible solid-state phase transition between the gamma and alpha phases of oleic acid was followed by 13C solid-state NMR spectroscopy. The factors that have a significant influence on the spectra of cis-monosaturated acyl chains are discussed.
