1-Hexanol triggered structural characterization of the worm-like micelle to vesicle transitions in cetyltrimethylammonium tosylate solutions
Vijay Kumar Patel,Debes Ray,Kulbir Singh,Ludmila Abezgauz,Gerrard Marangoni,Vinod K. Aswal,Pratap Bahadur +6 more
TL;DR: In this article, the effect of 1-hexanol on worm-like CTAT micelles was examined by viscosity, cryogenic transmission electron microscopy (cryo-TEM), nuclear magnetic resonance (NMR), and small-angle neutron scattering (SANS) measurements.
Effect of additives on the surface active and morphological features of 1-octyl-3-methylimidazolium halide aggregates in aqueous media
TL;DR: In this article, the influence of two salts as additives namely sodium chloride and sodium sulphate and a nonelectrolyte, 2-butoxyethanol on surface chemical and aggregation characteristics of ionic liquids (IL) was monitored through surface tension and small angle neutron scattering measurements.
Interaction, solubilization and location of p-hydroxybenzoic acid and its sodium salt in micelles of moderately hydrophilic PEO-PPO-PEO triblock copolymers.
TL;DR: The micellar transition was favored at higher PHBA concentration, temperature and for copolymers with more hydrophobicity, and the location of PHBA in micelle was elucidated by nuclear Overhauser enhancement spectroscopy (NOESY).
Micellization of sodium dodecyl sulfate and polyoxyethylene dodecyl ethers in solution
TL;DR: In this article, the effect of polyoxyethylene type nonionic surfactants (C12E) on the aqueous solution of sodium dodecyl sulfate (SDS) in absence and presence of NaCl was examined using small-angle neutron scattering (SANS), dynamic light scattering (DLS), and viscosity measurements.
Selective counterion condensation in ionic micellar solutions.
Vinod K. Aswal,P. S. Goyal +1 more
TL;DR: It is found that in equimolar surfactant to salt micellar solutions of CTABr/KCl and CTACl/KBr, the micellars sizes are larger in CTAC l/K Br than those in CTA br/K Cl.
