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.

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,

Thermodynamics of micelles [PDF]
Journal of Colloid and Interface Science, 1982 Abstract General equations of the thermodynamics of micellar systems and of a single micelle are given. Relations among the size distribution of micelles, their surface tension, and the CMC are established. An expression for the constant of the law of mass action is obtained in terms of surface tension.

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 ...

Association of counterions with micelles
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2003The properties of solutions of ionic surfactants depend on the nature of counterions, aas their association at the misellar surface compensates electrostatic repulsion between the charged heads, thus stabilizing the micellar phase. Above critical micellization concentration the conductivity of the surfactant solution is due to the presence of free ...

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)

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 major scientific challenge of the past decade pertaining to the field of soft matter has been to craft 'adaptable' materials, inspired by nature, which can dynamically alter their structure and functionality on demand, in response to triggers produced by environmental changes.

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 ...
