Critical micelle concentrations of gangliosides

Biochemistry, 1979
The micellar properties of mixed, bovine gangliosides and purified galactosyl-N-acetylacetylgalactosaminyl (N-acetylneuraminyl) galactosylglucosylceramide were studied by gel filtration, equilibrium dialysis, and band and boundary centrifugation in sucrose gradients.

Confinement induced critical micelle concentration shift

The Journal of Chemical Physics, 2007
In this work, extensive lattice Monte Carlo simulations were performed to investigate the influence of confinement on critical micelle concentration (CMC). It is found that the CMC of surfactants in a confined space is shifted from its bulk value, and the shift is affected by the presence of the confining boundaries, which induces both the finite size ...

Ferguson Principle and the Critical Micelle Concentration

Journal of Pharmaceutical Sciences, 1963
The thermodynamic activity values of a series of quaternary ammonium salts were calculated through the use of critical micelle concentrations. The correlation of these thermodynamic activities to the published values of their bactericidal activities is shown through application of the Ferguson principle.

Fluorescence probes for critical micelle concentration determination

Langmuir, 1985
The utility of pyrene and pyrene-3-carboxaldehyde as fluorescence probes for determining the critical micelle concentration (cmc) of nonionic (Tergitol25-L-9, Tergitol15-5-40, Neodol91-8), anionic (sodium decyl sulfate), and cationic (cetyltrimethylammonium bromide) surfactanb was investigated. The probes were dissolved in trace amounts (

Surfactant Diffusion Near Critical Micelle Concentrations

Journal of Solution Chemistry, 2002
Taylor dispersion and differential refractometry are used to measure mutual diffusion coefficients (D) for binary aqueous solutions of octylglucopyranoside, dodecylsulfobetaine, and sodium dodecyl sulfate (nonionic, zwitterionic and ionic surfactants, respectively).

Interfacial properties and critical micelle concentration of lysophospholipids

Biochemistry, 1989
The critical micelle concentration (cmc) of several lysophospholipids and of a lysophospholipid analogue was determined from surface tension measurements using the maximum bubble pressure method and/or 31P NMR. The use of the maximum bubble pressure method has now been extended to micromolar concentrations of surfactant, and the experimental parameters

Light Scattering from Hydrophobe-Uptake Spherical Micelles near the Critical Micelle Concentration

Langmuir, 2014
We have investigated aqueous micellar solutions of mixtures of a surfactant (dodecylpyridinium chloride) and a hydrophobe (1-dodecanol) near the critical micelle concentration (cmc), using simultaneous static and dynamic light scattering measurements.

Determination of the critical premicelle concentration, first critical micelle concentration and second critical micelle concentration of surfactants by resonance Rayleigh scattering method without any probe

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2011
The purpose of this work is to determine the values of critical premicelle concentration (CPMC), first critical micelle concentration (FCMC) and second critical micelle concentration (SCMC) of surfactants using a common spectrofluorophotometer by recording resonance Rayleigh scattering (RRS) signal without any probe.
