We study an unusual transition between two different types of self-assembled structures in aqueous solutions. Mixtures of a cationic surfactant, CTAB and the organic compound, 5-methyl salicylic acid (5mS) spontaneously self-assemble into unilamellar vesicles at room temperature… Contents Chapter 1.

Coil-to-Helix Transition of Poly(ethylene oxide) in Solution
Poly(ethylene oxide) (PEO) is a simple polymer with repeating units [- C - C - O -] soluble in organic and aqueous solvents. The carbon atoms are hydrophobic; the oxygen atoms are hydrophilic and participate in hydrogen bonding… Contents Chapter 1: Introduction Chapter 2: Prior Work Aqueous Solutions of Poly(ethylene oxide) Theory Experiment and Simulation [...]
