Physicochemical Characterization of Novel Aqueous Two-Phase System: Gemini Surfactant 12-2-12/NaBr/H2O
The results have shown that the coexisting two phases, one surfactant-rich and the other salt-rich, are stable and the phase behavior, volume ratio, and extraction efficiency of ATPS are strongly influenced by contents of Surfactant and salt.
Phase behavior of new aqueous two-phase systems: 1-Butyl-3-methylimidazolium tetrafluoroborate + anionic surfactants + water
The aqueous mixtures of an anionic surfactant (sodium dodecyl benzene sulfonate, SDBS) and an ionic liquid (1-butyl-3-methylimidazolium tetrafluoroborate, [Bmim]BF4) within a certain range of
Formation and characteristics of aqueous two-phase systems formed by a cationic surfactant and a series of ionic liquids.
Electrostatic interactions and aqueous two-phase separation modes of aqueous mixed oppositely charged surfactants system.
Composition analysis, rheological property investigation, and TEM images suggest that there are two kinds of aqueous two-phase systems (ATPSs), and on the basis of these experimental results and Kaler's cell model, two types of phase separation modes were proposed.
Phase behavior and microstructures in a mixture of anionic Gemini and cationic surfactants.
The macroscopic phase behavior and microscopic aggregate structure are related to the understanding of the possible mechanisms for the above phenomena.
Vesicle aggregation based on hydrophobic interactions
Vesicles were formed in aqueous mixtures of gemini anionic surfactant, O,O′-bis(sodium 2-alkylcarboxylate)-p-dibenzenediol (referred to as Cmϕ2Cm, m = 10, 12), and single-chain cationic surfactant,
Alkyltrimethylammonium bromide-induced aggregate transition of carboxylate gemini surfactant with a p-dibenzenediol spacer from networks to thread-like micelles to vesicles
The gemini surfactants, O,O’-bis(sodium 2-dodecyl-carboxylate)-p-dibenzenediol and O,O’-bis(sodium 2-decylcarboxylate)-p-dibenzenediol (denoted as C12ϕ2C12 and C10ϕ2C10, respectively), were
Partitioning of Dyes, Free Anthraquinones, and Tanshinones in Aqueous Two-Phase Systems of Cationic/Anionic Surfactants
The partition behaviors of some dyes, anthraquinones, and tanshiones in two kinds of aqueous two-phase systems (ATPSs) have been investigated. The partition constants (K) of ionic dyes and rhein in


Transformation of Vesicles in Aqueous Two‐Phase System of an Anionic Gemini Surfactant and a Cationic Conventional Surfactant Mixture
Transformation of vesicles formed in DTAB/C11-p-PhCNa aqueous surfactant two-phase (ASTP) was observed by the transmission electron microscopy (TEM). The trans-conformation of the gemini surfactant

The transition from vesicles to micelles induced by octane in aqueous surfactant two-phase systems
The transition from vesicles to micelles by adding octane into the dodecyl-pyridinium chloride (DPCl)/sodium laurate (SL), and dodecyltrimethylammonium bromide (DTAB)/SL aqueous two-phase systems has
Aqueous Two-Phase Systems of the Aqueous Mixtures of Cationic–Anionic Surfactants
Abstract The aqueous mixtures of cationic–anionic surfactants at relatively high concentrations (much higher than CMCs) can separate spontaneously into two immiscible aqueous phases. The formation
Two-Phase Region in the DTAB/SL Mixed Surfactant System
The phase behavior as well as the microstructures of the dodecyltrimethylammonium bromide (DTAB)/sodium laurate (SL) aqueous two-phase system has been studied. By using FF-TEM, dynamic light
