Structures of Aqueous Dispersions of Phosphatidylserine
Journal of Biological Chemistry, 1973 Abstract Dilute (g10% w/v) unsonicated phosphatidylserine dispersions in H2O contain spherical particles of a wide size distribution (0.1 to 15 µm). The majority have diameters between 0.1 to 2 µm and lack the multilamellar arrangement of bilayers typical of unsonicated lecithin dispersions. Sonication produces small thermodynamically unstable vesicles

Double-walled carbon nanotube dispersion via surfactant substitution [PDF]
, 2009 A new approach for the stabilisation of double-walled carbon nanotubes in aqueous media was developed. A low molecular weight surfactant was used in the first stage for the debundling of the nanotubes followed by substitution with a higher molecular ...

Autoxidation of cholesterol in aqueous dispersions and in monomolecular films
Journal of Lipid Research, 1972 The autoxidative formation of 7-ketocholesterol and diols from aqueous cholesterol dispersions and from cholesterol monomolecular films has been studied as a function of time. The rate of oxidation of cholesterol is much faster at the surface than in the

From colloidal dispersions to colloidal pastesthrough solid–liquid separation processes [PDF]
, 2005 Solid–liquid separation is an operation that starts with a dispersion of solid particles in a liquid and removes some of the liquid from the particles, producing a concentrated solid paste and a clean liquid phase.

Properties of Aqueous Dispersions of Phospholipid and Cholesterol [PDF]
European Journal of Biochemistry, 1968 Very little lipid can be extracted with diethyl ether or chloroform from aqueous dispersions of phosphatidylcholine, phosphatidylethanolamine and phosphatidic acid, or from mixed dispersions of phosphatidic acid and phosphatidylethanolamine with cholesterol.
