Comparison of neutron reflection and surface tension measurements of the surface excess of tetradecyltrimethylammonium bromide layers at the air/water interface

Synthesis, Surface Properties, and Hydrolysis of Chemodegradable Anionic Surfactants: Diastereomerically Purecis- andtrans-2,5-Disubstituted-1,3-dioxanes

“…The a quadratic fit. The minimum surface area per molecule, mixture of free acids 5 was then esterified with dimethyl A CMC , near the CMC was then calculated (17). The CMC sulfate to the mixture of methyl esters cis-6 and trans-6.…”

The Structures of Complexes of a Vermiculite Intercalated by Cationic Surfactants, a Mixture of Cationic Surfactants, and a Mixture of Cationic and Nonionic Surfactants

“…The preparation of the deuterated and partially deuterated surfactants used in the study have all been described in connection with other work (21,22). In all cases the level of deuteration of any labeled fragment was >96%.…”

Modeling of Equilibrium Adsorption and Surface Tension of Cationic Gemini Surfactants

“…Fitting the data to a quadratic polynomial results in different (larger, see Table 1) values for max than were previously reported when only the limiting linear slope near the cmc was considered (5). In general, simply evaluating this limiting slope results in smaller and perhaps inaccurate calculated densities (51,52). An additional advantage of using a higher order polynomial is the ability to calculate the surface density as a function of concentration rather than simply its maximum value.…”
