Ionic Transport of Hydrogen in Structured Soft Materials
EMSL Project ID
25698
Abstract
We will explore how the motion of hydrogen in the form of hydronium is controlled in a nanometer-sculpted multilayer composite water/hydrocarbon film, and how the motion of the ion alters the material. The role of the solvation potential, external electric field, and water structure will be varied to alter the ion motion. These will provide insight into transport of hydrogen across soft laminar materials, as in cells (fuel and living) and biofilms, where the water present is so small in at least dimension, that neither bulk water or ice properties can apply.
