1H high resolution magic angle spinning (HRMAS) NMR spectroscopy was used to
characterize the solvent environments in a series of poly (phenylene)-and poly (phenylene …

We compared the alkaline stability of three classes of anion exchange membranes that are
leading candidates for applications in platinum-free fuel cells. A methodology is presented …

A fundamental understanding of water transport and morphology is critical for improving
ionic conductivity in polymer membranes. In a series of random copolymer anion exchange …

The growth of an NMR signal due to diffusion of solute out of a thin membrane has been
investigated for the measurement of diffusion rates under conditions that are not suitable for …

Quantifying water and salt transport properties in polyamide is of growing importance as the
use of reverse osmosis membranes grows in many industries. Here, using solid-state …

Anion exchange membranes (AEMs) find widespread applications as an electrolyte and/or
electrode binder in fuel cells, electrodialysis stacks, flow and metal-air batteries, and …

Magnetic resonance microscopy of Nafion 117 is used to measure the spatial variation of
solvent dynamics in protonated (acid form) membranes immersed in solvent. Spatial …

The effects of ligand basicity on water and ion transport within hydrogel membranes are
investigated using a library of functionalizable poly (ethylene glycol) diacrylate (PEGDA) …

Mixed matrix membranes (MMMs) have gained significant attention due to their high water
permeability without the cost of salt rejection. However, the mechanism of water transport …
