چکیده
Polymeric micelles supply an environment, which can be cautiously regulated for drug delivery. The self-assembly of polymeric micellization is dynamic. Micellization thermodynamic describes how the system defines formation micelles. present study enables behavior surfactants in presence polymer to examined by conductometric and tensiometric methods. effects concentration temperature on thermodynamics a neutral soluble cationic cetyltrimethylammomium bromide (CTAB) surfactant mixture aqueous medium were investigated. To examine polymer-surfactant interaction, critical micellar (CMC) parameters such as standard free energy ∆G, enthalpy ∆H entropy ∆S are calculated using pseudo-phase model. Based CMC, ΔG, ΔH ΔH, dependence compensation effect discussed. This advanced work understand micelle stability compatibility comprehensively feasible systems.

Phase behavior of concentrated aqueous solutions of cetyltrimethylammonium bromide (CTAB) and sodium hydroxy naphthoate (SHN).
We have characterized the phase behavior of mixtures of the cationic surfactant cetyltrimethylammonium bromide (CTAB) and the organic salt 3-sodium-2-hydroxy naphthoate (SHN) over a wide range of surfactant concentrations using polarizing optical microscopy and X-ray diffraction. A variety of liquid crystalline phases, such as hexagonal, lamellar with and without curvature defects, and nematic,...
متن کاملSilica nanoparticles separation from water: aggregation by cetyltrimethylammonium bromide (CTAB).
Nanoparticles will inevitably be found in industrial and domestic wastes in the near future and as a consequence soon in water resources. Due to their ultra-small size, nanoparticles may not only have new hazards for environment and human health, but also cause low separation efficiency by classical water treatments processes. Thus, it would be an important challenge to develop a specific treat...

abstract reception environment has considerable effects on accepting a translation. as the expectations of a target culture and its values and needs change throughout history, its criteria for accepting a translation or rejecting it will change accordingly (gentzler, 2001). the expectations of iran, as the reception environment in the present study, have changed after the islamic revolution. i...
