Tuning polymeric chiral surfactants for enhanced enantiomeric recognition in micellar electrokinetic chromatography
… characterization, and the application of polymeric surfactants in micellar electrokinetic chromatography (MEKC). Sodium undecenoyl-L-Leucinate (L-SUL) was synthesized and modified by use of alkali metal counterions, alcohols, and Triton X-102. Characterization of the modified poly-L-SUL …

Synthesis and Use of Chiral Surfactants.
… been previously shown that micelles formed from surfactants with chiral head groups serve to induce a chiral reaction medium, leading to enhanced enantioselectivities in the reaction products. This utilization of chiral surfactants will offer an economical alternative to traditional chial …

Structure and Dynamics of Polyhedral Oligomeric Silsesquioxane (POSS) and Poly(Ethylene Glycol) (PEG) Based Amphiphiles as Langmuir Monolayers at the Air/Water Interface
Throughout the study of polymeric Langmuir monolayers at the air/water (A/W) interface, the Wilhelmy plate and Langmuir-Blodgett (LB) techniques along with Brewster angle microscopy (BAM) have been identified as key methods for acquiring structural, thermodynamic, rheological and morphological …

Novel amphiphilic diblock copolymers by RAFT-polymerization, their self-organization and surfactant properties
… of end-group functionalization. The new macro-surfactants form micelles in water, whose size and geometry strongly depend on their composition, according to dynamic and static light scattering measurements. The micellization is shown to be thermodynamically favored, due to the high …

Analytical separations using packed and open-tubular capillary electrochromatography
… as analytes. In the second study, the anionic polymeric surfactant poly (sodium N-undecanoyl-L-leucylvalinate), poly (L-SULV), was used as the chiral discriminator for the separations of several drug analytes. Reproducibility of the PEM coating was evaluated by computing the relative standard …

Solubility enhancement, mechanical properties and taste masking of poorly water soluble compounds by optimizing hot melt extrusion processing
… using HME to disperse a poorly soluble drug in a polymeric carrier matrix, forming a solid dispersion. This method can be used to form both amorphous and crystalline dispersions, but for solubility enhancement amorphous dispersions are used because of the free energy benefits associated with them. …
