Interaction and physicochemical parameters of dodecyltrimethylammonium bromide and crystal violet dye mixture in aqueous alcohols and urea solution: Effects of change in composition and temperature

Physicochemical parameters and modes of interaction associated with the micelle formation of a mixture of tetradecyltrimethylammonium bromide and cefixime trihydrate: effects of hydrotropes and temperature

“…In the literature, both upward and downward trends for −Δ G 0 m value with the change of thermal condition of experiment for the aggregation process also reported. 57,58,77,78…”

“…Another signicant element that hinders the formation of micelles is the decrease of water arrangement near the nonpolar part of TTABs and drugs, i.e., the value of CMC undergoes an upsurge. 77 Therefore, whether the values of CMC grow or reduce at the examined range of temperature depends on the extent of the aforementioned two parameters. In the case of the TTAB + CMT mixed system in an aqueous medium, as well as in the presence of HTs, the last factor controlled the process of micellization more signicantly than the rst one within the range of temperature.…”

“…Similar results were also observed in our earlier study. 76,77 Rehman et al 36 also reported the increasing trend of CMC for pure surfactants (SDS and CTAB) or surfactants with polylactic acid (PLA) solution. It was also reported that the micellization of 3-(1-alkyl-3-imidazolio) propane-sulfonate [ImS3-R] was easier at lower temperatures but became disfavoreable at higher temperatures.…”

“…In the literature, both upward and downward trends for −DG 0 m value with the change of thermal condition of experiment for the aggregation process also reported. 57,58,77,78 The values of DH 0 m and DS 0 m are the key factors in determining the supramolecular interactions between drug (CMT) and surfactant (TTAB) in the presence of HTs. In the present study, the values of DH 0 m for every experimental trial were found negative manifesting the process was exothermic reactions (Table 4).…”
