“…30,54 The duality of the structure of spherical micelles of alkylammonium chloride is proven by us with the help of NMR. 55 We found the hysteresis during solubilization to be in two solubilization series: n-hydrocarbons − sodium dodecyl sulfate, propane − sodium alkyl sulfate. 54 The hysteresis of properties is observed in bistable systems.…”

“…The activation energies of the transition of methylene groups from two stable states through the unstable state are equal to 1.4 and 3.7 kJ mol –1 . These values were obtained when micellization was tested by hydrophobic probe molecules of gaseous hydrocarbons in the process of solubilization. , The duality of the structure of spherical micelles of alkylammonium chloride is proven by us with the help of NMR …”

Polyamorphous transitions in supercooled water, porous substances, solutions of polyols, and proteins are studied intensively. They accompany the self-organization of hydrocarbons and surfactants. In this study, the methods of polyamorphous transition identification are proposed, and their dependence on hydrocarbons and surfactant concentration and sizes is investigated. The place of polyamorphous transitions in the general theory of phase separation is determined, and their bistability, self-oscillations, hysteresis, fluctuations, cooperative effect, enthalpy, and entropy are described. Surface, volume, and diffusion instabilities of polyamorphous transitions are analyzed. Technologies based on the properties of polyamorphous transitions are proposed.

“…Such tech nology is based on concentrating simple or complex metal ions during ion flotoextraction [18] at the first stage, with the subsequent synthesis of nanoparticles from the obtained precursors in a system of direct micelles at the second stage [19]. The flotoextraction process is not energy intensive, and it can be applied to large volumes of diluted water solutions.…”

A method for obtaining nanoparticles in a system of direct micelles of amphiphiles using ion flo toextraction for concentrating ions from diluted water solutions is developed. Nanoparticles of the composi tion CoFe 2 O 4 with a structure close to spinel are obtained. It is established that the particles consist of two components: well formed phases of cobalt ferrite CoFe 2 O 4 and its amorphous analog. It is shown that the nanoparticles have a maximum size distribution ranging from 4 to 6 nm; on a carbon substrate, they self orga nize into a periodic colloidal structure. It is concluded that nanosized CoFe 2 O 4 powder has a blocking tem perature of about 45 K, a magnetic moment of about 0.85-0.9µ B at a temperature of 0 K, and the Neöl tem perature lies in the range of 110 to 250 K.
