Solution-induced reconstructive epitaxial nucleation on pseudoflat surfaces of fractal gel-grown ammonium chloride

Article Abstract:

The morphological manifestation of regular fractal patterns in ammonium chloride and transition from ordinary to fractal morphology at the crystallographic and molecular level by means of the Hartman-Perdok theory is studied. The experimental results for growth out of vapor ({211} and {110}) and out of polar solutions ({211}, {110}, and/or {111}), in the ordinary as well as fractal morphological regimes are found to agree with the theoretically predicted growth forms as a function of growth conditions.

Tuning the contour lengths and persistence lengths of cationic micelles: the role of electrostatics and specific ion binding

Article Abstract:

Small-angle scattering are used to obtain detailed information on micellar contour lengths and persistence lengths, a measure of micellar flexibility, for mixed micelles of cetyltrimethylammonium 2,6-dichlorobenzoate and cetyltrimethylammonium chloride in water as a function of surfactant and salt concentrations and the relative amounts of the two counterions at the micellar surface.

Ionic liquids: ion mobilities, glass temperatures, and fragilities

Article Abstract:

The relative properties of a variety of ionic liquid types are studied to arrive at a broad picture of the physical behavior of these systems. The relation of fluidity to conductance is considered in terms of a Walden plot that is shown to provide a useful basis for organizing the observations on ionic liquids and solutions.
