The binary phase diagram of tetraethylene glycol decanoyl ester (C9COE4) was investigated in the micellar region by PGSE-NMR (pulse field gradient spin echo nuclear magnetic resonance) and in the lamellar liquid crystalline state by 2H NMR. Its behavior was compared to the ether counterpart, tetraethylene glycol decanoyl ether (C10E4), whose phase diagram is well-described. The determination of the self-diffusion coefficient as a function of concentration permitted not only a determination of… Expand

Effect of L64 on the Phase Behavior of 1‐Dodecyl‐3‐methylimidazolium Chloride/Water System
Phase behavior of ternary system involving surfactant-like ionic liquid 1-dodecyl-3-methylimidazolium chloride ([C12mim]Cl), water, and nonionic surfactant PEO-PPO-PEO block copolymer (Pluronic L64)Expand
Effect of sodium diclofenac loads on mesophase components and structure.
Findings show that loads of solubilized drug may affect the structure of its vehicle and, as a result, its transport across skin-blood barriers, and the structural changes of the mesophase may also aid controlled drug delivery. Expand
Nuclear Magnetic Resonance Investigation of the Effect of pH on Micelle Formation by the Amino Acid-Based Surfactant Undecyl l-Phenylalaninate.
Two-dimensional NMR studies revealed that in und-Phe micelles, the aromatic rings on the phenylalanine headgroups were rotated toward the hydrocarbon core of micelle, suggesting that l-arginine is attached perpendicular to the micelle surface through its guanidinium functional group with the remainder of the molecule extending into solution.

Hydrotropic properties of alkyl and aryl glycerol monoethers.
Three pentyl and three aryl 1-O-monoglyceryl ethers prepared via a green catalytic route were investigated as hydrotropic solvents, or "solvo-surfactants", as regards to their surface-active properties and good solubilizing abilities. Expand
Micelles and aggregates of oxyethylated isononylphenols and their extraction properties near cloud point.
NMR spectroscopy and dynamic light scattering techniques were used to study the structural and dynamic properties of micellar solutions of nonionic surfactants of a homologous series of oxyethylated isononylphenols in a wide range of temperatures, including cloud points. Expand
A Surface Site Interaction Point Method for Dissipative Particle Dynamics Parametrization: Application to Alkyl Ethoxylate Surfactant Self-Assembly
A first-principles computational method has been developed so that bead interaction parameters can be calculated directly from ab initio gas-phase molecular electrostatic potential surfaces of the molecular fragments that represent the beads. Expand
