Micelle formation of sodium ursodeoxycholate and solubilization into the micelle
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2000Abstract The micellization of sodium ursodeoxycholate (NaUDC) was studied at 298.2 K by aqueous solubility at different pH values. Using an association model of ursodeoxycholate anion without sodium counterion, the aggregation number ( n ) of the ursodeoxycholate micelle was evaluated and found to increase with the total concentration, indicating

Solubilization of hydrocarbons by surfactant micelles and mixed micelles
Journal of Colloid and Interface Science, 1989Abstract Extensive and highly precise vapor pressure results have been obtained for solutions of cyclohexane and hexane in cationic, anionic, and nonionic surfactant micelles, and in mixed anionic-nonionic, cationic-nonionic, and anionic-cationic micelles.

On the Thermodynamics of Reverse Micelles: Effect of Water on Micellization
Colloid Journal, 2020Water may be involved in reverse micelle formation either in the form of a hydration shell or as a solubilisate. Both cases have been analyzed within the framework of a theory based on the mass action law and the definition of the critical micelle concentration (CMC) via the constant of this law.

ChemInform Abstract: ON THE STRUCTURE OF MICELLES
Chemischer Informationsdienst, 1984Les etudes cinetiques de l'oxydation des olefines micellaires par des ions permanganate, en solution aqueuse, a 25°C et pH 12, montrent qu'une olefine terminale est oxydee avec une rapidite superieure de 2 ordres que les olefines internes. Ce fait est interprete par le desordre et les enroulements rencontres dans la region de Stern riche en ...

Micelles and Reversed Micelles: A Historical Overview
1984This is a review of the historical development of models for micelle formation in aqueous solution, lyotropic liquid crystals, reversed micelles and microemulsions. The current model of micelle formation was suggested about fifty years ago, while the quantitative development of thermodynamic and kinetic models is relatively recent.

Hyperfine Interactions, 1991
A pseudo first-order term has been added to the kinetic analysis of micelle-mediated muonium reactions. It is discussed with respect to enhancements of several orders of magnitude for reactions such as that of 2-propanol. It covers the possibility of ‘trapping’ of muonium followed by tunneling.

Casein Micelles and Micelles of ϰ- and β-Casein
1982The tendency of proteins to associate in aqueous solution is well known. Most proteins form oligomers or undergo a series of consecutive association steps. A limited number, however, among which are ϰ- and β-casein, exhibit soaplike micellization.

Chemical Communications, 2013
Rhythmic oscillation of the scattering intensity and hydrodynamic radii of a block copolymer solution driven by the Belousov-Zhabotinsky (BZ) reaction was demonstrated without any on-off switching of external stimuli. This is the first report on a synthetic block copolymer that realizes the novel concept of self-assembly assisted by a dissipative ...

Polymeric micelles are self-assemblies of amphiphilic polymers, which exhibit greater thermodynamic and kinetic stability than micelles of classical surfactants. Block copolymers can be synthesized to bear a variety of chemical functionalities both in the hydrophobic and in the hydrophilic blocks, which enables the preparation of micelles with diverse ...
