Mixed Micelles of Anionic−Nonionic and Anionic−Zwitterionic Surfactants Analyzed by Pulsed Field Gradient NMR
TL;DR: In this article, the micellar composition of two binary surfactant systems, that is, sodium dodecyl sulfate (SDS)/pentaethylene glycol monodecyl ether (C10E5) and SDS/lauryl amido propyl betaine (LAPB), has been analyzed by pulsed gradient spin−echo NMR (FT-PGSE NMR).

Surfactant Molecules Intercalated in Laponite as Studied by 13C and 29Si MAS NMR
TL;DR: In this paper, the structure and dynamics of surfactant molecules intercalated in Laponite have been characterized by solid-state 13C NMR relaxation times and 13C- and 29Si-detected proton relaxation times.

Order acquisition by clay platelets in a magnetic field. NMR study of the structure and microdynamics of the adsorbed water layer
TL;DR: In this article, the Ecca Gum BP bentonite in heavy water is oriented by the magnetic induction field in the probe of an NMR spectrometer, which gives rise to residual quadrupolar splittings for 2 H and 17 O nuclei within the water solvent.

Self-assembly of poly(ethylene oxide)-b-poly(epsilon-caprolactone) copolymers in aqueous solution.
TL;DR: The experimental results suggest that micellization occurs at low concentration and results in a mixture of unimers and spherical micelles that exchange slowly, and no significant modification is observed when poly(gamma-ethylene oxide) replaces poly(epsilon-caprolactone) in the diblocks.

TL;DR: Preliminary two-dimensional NMR measurements with nuclear Overhauser enhancement have confirmed the spatial vicinity between SDS and the constitutive blocks of the copolymer.
