Physico-chemical investigation of nanostructures in liquid phases: Nickel chloride ionic clusters confined in sodium bis(2-ethylhexyl) sulfosuccinate reverse micelles

Self-assembly in surfactant-based liquid mixtures: Bis(2-ethylhexyl)phosphoric acid/bis(2-ethylhexyl)amine systems

“…This because, mirroring the typical structural features of amphiphilic molecules, these systems are characterized by the coexistence of polar and apolar nanodomains separated by extensive interfacial surface which allows the simultaneous solubilization of hydrophilic, hydrophobic and amphiphilic solute species and their preferential confinement in different nanoregions [1,2].…”

How self-assembly of amphiphilic molecules can generate complexity in the nanoscale

“…For example, micelles, which are usually dealt with closed structures with specific characteristics (size, shape) are in reality evanescent and living for milliseconds [4]. This aspect is very important since, just to quote a mere example, its comprehensions allowed the exploitation, among the innumerable methods of synthesis of nanoparticles (see the huge literature available), of surfactant-based techniques to soft-coat nanostructures [5][6], to prepare ionic clusters with novel characteristics [7], to prepare composite nanoparticles [8] and metal-semiconductors nanocomposites with interesting optical properties [9].…”

“…Interestingly, the opportune treatment of microemulsion-based systems has also allowed the preparation of salt-soluble substances, both organic [26][27] and inorganic [7]. This technique has proved to be successful in governing nanoparticle size and shape and in arranging nanoparticles in defined 2D and 3D arrangements.…”

Self-assembly in surfactant-based mixtures driven by acid–base reactions: bis(2-ethylhexyl) phosphoric acid–n-octylamine systems

“…Since these peaks occur at q1!3 and q1!4 where q1 corresponds to the interplanar distance of 1.54 nm 21 observed in the SAXS spectrum, it can be concluded that this sample forms a reverse hexagonal bidimensional structure, an arrangement frequently observed in pure dichained surfactants. [16][17][18][19] Taking into account this geometry, the lattice parameter (a) through the relation q(10) = 4p/3a turns out to be a = 1.78 nm, so that a schematic representation of the building block of the local structures of the X NOA = 0.5 sample can be sketched (see Fig. 8).…”
