Synthesis of amphiphilic dendrons and their interactions in aqueous solutions with cetyltrimethylammonium p-toluenesulfonate (CTAT)
(Elsevier Inc, 2009-04)
In this work, we report synthesis and rheology of an interesting structured fluid based on the self-assembly of amphiphilic dendrons and wormlike micelles. Two amphiphilic dendrons were synthesized by the combination of ...
The Thermal Signature Of Wormlike Micelles

Aqueous sodium oleate-sodium dehydrocholate mixtures at low concentration
(Springer, 2003-10)
The aqueous mixed system sodium dehydrocholate (NaDHC)-sodium oleate (NaOL) was studied by several methods to determine the influence of the hydrophobic structure of both surfactants in the mixed micellization and the ...
Molecular interactions between Pluronic F127 and saponin in aqueous solution
(2020-02-01)
Nanotechnology is important for the development of new materials capable to improve the development of novel drug delivery systems. Such systems may result in more efficient therapeutic effects with reduced toxicity and ...
Structural organization of cetyltrimethylammonium sulfate in aqueous solution: the effect of Na2SO4
(Elsevier B.V., 2006-07-15)
We used dynamic light scattering (DLS), a steady-state fluorescence, time resolved fluorescence quenching (TRFQ), tensiometry, conductimetry, and isothermal titration calorimetry (ITC) to investigate the self-assembly of ...

Synergism study of mixtures of ionic and nonionic surfactants in enhanced oil recovery adsorption
(ASSOCIAÇÃO BRASILEIRA DE PETRÓLEO E GÁS - ABPG, 2017-07-18)
Adsorption of surfactants from aqueous solutions in porous media is fundamental in enhanced oil recovery (EOR) because surfactant loss reduces the effectiveness of the chemical solution injected, making the process ...
Salt-induced sphere-to-disk transition of octadecyltrimethylammonium bromide micelles
(Amer Chemical Soc, 1998-03-31)
We have used surface tension measurements, differential scanning calorimetry (DSC), dynamic light scattering (DLS), and cryo-transmission electron microscopy (cryo-TEM) to investigate the dynamic and structural behavior ...
Physicochemical characterization of aqueous micellar systems formed by environmentally friendly salts
(Elsevier Science, 2015-05)
In this work, environmentally friendly aqueous micellar two-phase systems containing nonionic surfactants (Triton X-114, Triton X-100 and Genapol X080) and organic salts (sodium citrate and sodium tartrate) were characterized. ...
