Dielectric relaxation of aqueous solutions of hydrophilic versus amphiphilic peptides
Article Abstract:
The molecular dynamics simulations of the frequency-dependent dielectric relaxation (DR) spectra at room temperature for two aqueous peptide systems at two different concentrations are reported. The DR analysis provides insight into the difference of frequency relaxation process for high-concentration amphiphilic peptide and hydrophilic peptide.

Emulsion stabilization and inversion using a pH- and temperature-sensitive amphiphilic copolymer
Article Abstract:
A versatile amphiphilic diblock copolymer is used for forming oil-in-water (o/w) or water-in-oil (w/o) emulsions depending on pH and temperature. The emulsion type is reversibly switched along a temperature scan under stirring and the lower stability of the w/o emulsions is attributed to a lack of electrostatic repulsion.

Kinetics of pH response for copolymer films with dilute carboxylate functionality
Article Abstract:
The various effects of film composition and the thickness on the rate of pH-induced response of various copolymer films with dilute carboxylate functionality are explained. The analysis reveals that the response of the films increases with decreasing thickness.
