  2. Micelle - Wikipedia

    en.wikipedia.org/wiki/Micelle

    The formation of micelles can be understood using thermodynamics: Micelles can form spontaneously because of a balance between entropy and enthalpy. In water, the hydrophobic effect is the driving force for micelle formation, despite the fact that assembling surfactant molecules is unfavorable in terms of both enthalpy and entropy of the system ...

  3. Thermodynamics of micellization - Wikipedia

    en.wikipedia.org/wiki/Thermodynamics_of_micelliz...

    In colloidal chemistry, the critical micelle concentration (CMC) of a surfactant is one of the parameters in the Gibbs free energy of micellization. The concentration at which the monomeric surfactants self-assemble into thermodynamically stable aggregates is the CMC.

  4. Krafft temperature - Wikipedia

    en.wikipedia.org/wiki/Krafft_temperature

    In colloidal chemistry, the Krafft temperature (or Krafft point, after German chemist Friedrich Krafft) is defined as the minimum temperature at which the formation of micelles occurs in a solution of dissolved surfactant. It has been found that solubility at the Krafft point is nearly equal to critical micelle concentration (CMC). Below the ...

  5. Critical micelle concentration - Wikipedia

    en.wikipedia.org/wiki/Critical_micelle_concentration

    In colloidal and surface chemistry, the critical micelle concentration (CMC) is defined as the concentration of surfactants above which micelles form and all additional surfactants added to the system will form micelles. [1] The CMC is an important characteristic of a surfactant.

  6. Lipid bilayer fusion - Wikipedia

    en.wikipedia.org/wiki/Lipid_bilayer_fusion

    Since PE has a small headgroup and readily forms inverted micelle phases it should, according to the stalk model, promote the formation of these stalks. [11] Further evidence cited in favor of this theory is the fact that certain lipid mixtures have been shown to only support fusion when raised above the transition temperature of these inverted ...

  7. Micellar solution - Wikipedia

    en.wikipedia.org/wiki/Micellar_solution

    Schematic of a micellar solution showing spherical micelles distributed in water (solvent) and having no long-range positional order. In colloid science, a micellar solution consists of a dispersion of micelles (small particles) in a solvent (most usually water).

  8. Lipid bilayer - Wikipedia

    en.wikipedia.org/wiki/Lipid_bilayer

    The lipid bilayer is very thin compared to its lateral dimensions. If a typical mammalian cell (diameter ~10 micrometers) were magnified to the size of a watermelon (~1 ft/30 cm), the lipid bilayer making up the plasma membrane would be about as thick as a piece of office paper. Despite being only a few nanometers thick, the bilayer is composed ...

  9. Micellar cubic - Wikipedia

    en.wikipedia.org/wiki/Micellar_cubic

    The amphiphiles' hydrocarbon tails are contained on the inside of the micelle and hence the polar-apolar interface of the aggregates has a positive mean curvature, by definition (it curves away from the polar phase). The first pure surfactant system found to exhibit three different type I (oil-in-water) micellar cubic phases was observed in the ...
