13C NMR investigation of the structure of alkylammonium chloride micells in aqueous solutions

How ionic species structure influences phase structure and transitions from protic ionic liquids to liquid crystals to crystals

Phase behaviour of n-alkylammonium (C6 to C16) nitrates and formates was characterised using synchrotron small angle and wide angle X-ray scattering, differential scanning calorimetry, cross polarised optical microscopy and FTIR.

Liquid Polyamorphous Transition and Self-Organization in Aqueous Solutions of Ionic Surfactants

Polyamorphous transitions in supercooled water, porous substances, solutions of polyols, and proteins are studied intensively. They accompany the self-organization of hydrocarbons and surfactants. In this study, the methods of polyamorphous transition identification are proposed, and their dependence on hydrocarbons and surfactant concentration and sizes is investigated. The place of polyamorphous transitions in the general theory of phase separation is determined, and their bistability, self-oscillations, hysteresis, fluctuations, cooperative effect, enthalpy, and entropy are described. Surface, volume, and diffusion instabilities of polyamorphous transitions are analyzed. Technologies based on the properties of polyamorphous transitions are proposed.
