Wrapping Nanotubes with Micelles, Hemimicelles, and Cylindrical Micelles
Small, 2009AbstractThis work uses a simple model based on hydrophobic and hydrophilic forces to investigate the molecular dynamics that lead to the supramolecular self‐assembly of surfactants around carbon nanotubes (CNTs). The effects of the concentration and the structure of surfactants are explored.

Micelle formation of sodium cholate and solubilization into the micelle
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1998The micellization of sodium cholate (NaC) was studied at 298.2 K by aqueous solubility at different pH values. Using a stepwise association model of cholate anions without the sodium counterion, the aggregation number (n) of the cholate micelle was evaluated and found to increase with the total concentration, indicating that the mass action model ...

CHARMM-GUI Micelle Builder for Pure/Mixed Micelle and Protein/Micelle Complex Systems
Journal of Chemical Information and Modeling, 2013Micelle Builder in CHARMM-GUI, http://www.charmm-gui.org/input/micelle , is a web-based graphical user interface to build pure/mixed micelle and protein/micelle complex systems for molecular dynamics (MD) simulation. The robustness of Micelle Builder is tested by simulating four detergent-only homogeneous micelles of DHPC (dihexanoylphosphatidylcholine)

Organic photochemical reactions conducted in micellar solutions are reviewed from the standpoint of systematizing and correlating published results. Five common effects are found to distinguish and characterize micellar photochemistry relative to conventional solution photochemistry: “super” cage effects, local concentration effects, viscosity effects,

Annual Review of Physical Chemistry, 1992
We have shown that there is a close relationship between the surfactant film properties, the bulk structures, the interfacial tension with oil (or water) and even the dynamic properties in micellar and microemulsion systems. The evolution from spherical micelles to tubular, cubic, lamellar or sponge phases is now qualitatively well understood.

Coexistence of small micelles with large micelles
The Journal of Physical Chemistry, 1988Analyse detaillee du quasar 3C 273 par plaques electronographiques UBV a haute resolution (FWHM≃1''). De nouvelles composantes du jet optique ont ete detectees et les indices de couleur U-B et B-V sont constants sur tout le jet sauf pour un point a 15.4'' du quasar plus bleu que le reste de 0.3 nag.

Thermodiffusion of Charged Micelles
Physical Review Letters, 2005We study diffusion of charged nanoparticles in a temperature gradient and derive the corresponding Ludwig-Soret transport coefficient. Charge effects are found to enhance thermodiffusion by up to 2 orders of magnitude. We show that the inverse Soret coefficient 1/S(T) is a linear function of the colloid density n; the proportionality factor, or second ...

A phosphate-induced sub-micelle-micelle equilibrium in reconstituted casein micelle systems
Journal of Dairy Research, 1979SUMMARYIn reconstituted casein systems, complete sub-micelles were previously observed only under extreme conditions of ionic strength, namely a NaCl concentration of 2 M or greater. However, studies with the analytical ultracentrifuge on phosphate-containing casein systems revealed that under certain conditions, a stable sub-micelle-micelle ...

Accelerated Micellization and Aggregation of Pluronic Micelles by Interaction with Heparin
Journal of Biomaterials Science, Polymer Edition, 2010The effect of attractive interaction between heparin and Pluronic co-polymer, two important macromolecules in biomedical applications, on the micellar state of Pluronic co-polymer was characterized. By the addition of heparin, the critical micellization temperature (CMT) of Pluronic solution decreased, indicating that heparin promoted micellization ...

Influence of the Polymer–Micelle Interaction on Micelle‐Substrate Binding
Journal of Pharmaceutical Sciences, 2010In an attempt to investigate how a nonionic polymer, hydroxypropyl methylcellulose (HPMC), interacts with a cationic surfactant, hexadecyltrimethylammonium bromide (CTAB), a dialysis method was employed for directly measuring the HPMC-CTAB interaction.
