A Fundamental Study of the Transport Properties of Aqueous Superacid Solutions

Suarez, S.N.; Jayakody, J.R.P.; Greenbaum, S.G.; Zawodzinski, T.; Fontanella, J.J. (Journal of Physical Chemistry B, 2010)

An extensive investigation of the transport properties of aqueous acid solutions was undertaken. The acids studied were trifluoromethanesulfonic (CF3SO3H), bis(trifluoromethanesulfonyl)imide [(CF3SO2)2NH], and para-toluenesulfonic ...
High pressure studies of hydrated NAFION membranes: Dielectric relaxation and deuteron NMR

McLin, M.G.; Wintersgill, M.C.; Fontanella, J.J.; Chen, R.S.; Jayakody, J.R.P.; Greenbaum, S.G. (Solid State Ionics, 1993)

Audio frequency electrical conductivity/dielectric relaxation and nuclear magnetic resonance studies of NAFION-117 have been carried out at pressures up to 0.3 GPa (3 kbar). For some samples, the electrical conductivity ...
Studies of Water in Nafion Membranes: Using Deuteron and Oxygen?17 Nuclear Magnetic Resonance, and Dielectric Relaxation Techniques

Chen, R.S.; Jayakody, J.R.P.; Greenbaum, S.G.; Pak, Y.S.; Xu, G.; McLin, M.G.; Fontanella, J.J. (Journal of Electrochemical Society, 1993)

Deuteron and oxygen-17 nuclear magnetic resonance measurements and dielectric relaxation studies of Nafion-117 membranes with variable water content (approximately 5-18% by weight) have been carried out. Glassy behavior ...
