| Description
| - Crystallisation - Aqueous microemulsions of hydrophobic organic liquids are used to be applied in some cases for separation of soft microparticles from aqueous dispersions in a regime of “oil flotation”. A mechanism of this separation is based on different wetting of particles by water and organic liquids. A reverse way of this process can be applied on a molecular level when different wetting is replaced by different solubility of some molecules in both phases of a microemulsion. Elemental nanoparticles – C60 macromolecules are well soluble in toluene (3.2 mg/l) in contrast to water. By a method of emulsion crystallization globular nanoparticles of required size, stability in aqueous dispersion can be prepared. The 50 % solution of C60 in toluene after mixing with water by intensive turbulence in an ultrasound bath was transferred into a microemulsion with a maximal portion of droplets with the radius of 381.6 nm. During continual bubbling under lower pressure this emulsion was permanently kept at the temperature of 20 oC till toluene was totally evaporated. A resulting aqueous dispersion contained mostly globular nanoaggregates nC60 with the radius of 26.1 nm. Their size predicted by a nucleation model matched the content of C60 molecules in an emulsion microdroplet and depended on the concentration of C60 in toluene and quality of the initial microemulsion.
