The shape of a micelle is directly dependent on the packing parameter of the surfactant. Surfactants with a packing parameter of N S {\displaystyle N_{\text{S}}} ≤ 1/3 appear to have a cone-like shape which will pack together to form spherical micelles when in an aqueous environment (top in figure).
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 ...
[7] [8] [9] These fit functions are based on a model for the concentrations of monomeric and micellised surfactants in solution, which establishes a well-defined analytical definition of the CMC, independent from the technique. The CMC is the concentration of surfactants in the bulk at which micelles start forming.
The policy endorsed the adoption of a uniform pattern of school education across the country consisting of 10 years of general education program followed by 2 years of diversified schooling. The NCERT is also behind the formation of the National Science Talent Search Scheme (NTSS) in the year 1963.
