Depletion of water-in-oil aggregates from poor solvents: Transition from weak aggregates towards reverse micelles

Polycarbazole by chemical oxidative interfacial polymerization: morphology and electrical conductivity based on synthesis conditions

“…The carbazole monomers are attracted to each hexagonal micelle. For the PCB synthesized with CTAB, it produces a connected hollow sphere structure because the reverse micelles generate some pore spaces within the system and produce a fusion and aggregation of the hollow spheres . For the PCB synthesized with SDS, it produces small hollow spheres due to the vesicles formed from carbazole micelles.…”

Characterization of reversed micelles formed in solvent extraction of thorium(IV) by bis(2-ethylhexyl) phosphoric acid. Transforming from rodlike to wormlike morphology

“…However, compared with DMDOHEMA system [10,11], the aggregates in HDEHP system is much larger. Therefore, these large aggregates may be formed by the interactions of small aggregate of complexes.…”

“…9), and the equilibrium constant and the distribution ratio were expressed by Eqs. (10) and (11) (11) where equals to the slopes of the above plots. One can see that log is a linear function of log HDEHP with a slope of 3, thus is proposed to be 3.…”

“…The introduction of a cation salt in the organic solution containing , -dimethyl-, -dioctylhexylethoxy malonamide (DMDO-HEMA) converts the loose reverse aggregate into classical reverse micelles with a strong polar core enclosed. The reverse micelles interact through attractive van der Waals interactions and coalesce into rodlike polynuclear europium(III)-containing aggregates with metal centers bridged by nitrate anions [10,11]. In the synergistic extraction of Dy 3+ by tri--butyl phosphate (TBP) and di--butyl phosphoric acid (HDBP), largest reversed micelles were observed at an optimal ratio of the two extractants, showing a micellization mechanism of synergism [12,13].…”

Depletion forces in single phase and multi-phase complex fluids

“…Progress in small angle scattering of weakly scattering systems, as well as the molecular dynamics could demonstrate this in the case of weak aggregates that are the intermediary form between organometallic complexes and more classical "reverse micelles" containing hundred molecules or more per micelle. These weak reverse aggregates of 10-20 molecules seem to occur frequently [24]. In the case of ionic aggregates containing 10-30 ions, such as the DOLLOP discovered by Gebauer and Cölfen in 2008 [25], or even the surfactant-free microemulsions [26], and for which the structural unambiguous proof of existence has been available only recently [27].…”
