A multinuclear NMR study of ion transport in P(EO)nLiBETI complexes

Suarez, S.N.; Abbrent, S.; Jayakody, J.R.P.; Greenbaum, S.G.; Shin, J.H.; Passerini, S. (Solid State Ionics, 2005)

A study of ion transport in P(EO)nLiBETI complexes was undertaken, using both AC impedance and nuclear magnetic resonance (NMR) spectroscopy. 1H, 7Li and 19F NMR techniques were used to investigate structure and dynamics ...
New membranes based on ionic liquids for PEM fuel cells at elevated temperatures

Ye, H.; Huang, J.; Xu, J.J.; Kodiweera, N.A.C.; Jayakody, J.R.P.; Greenbaum, S.G. (Journal of Power Sources, 2008)

Proton exchange membrane (PEM) fuel cells operating at elevated temperature, above 120 �C, will yield significant benefits but face big challenges for the development of suitable PEMs. The objectives of this research are ...
Two new siloxanic proton conducting membranes: Part II. Proton conductivity mechanism and NMR study

di Noto, V.; Vittadello, M.; Kalfan, A.N.; Greenbaum, S.G. (Electrochimica Acta, 2005)

The synthesis and structural characterization of two types of membranes with formulas {Si(CH3)3O[Si(CH3)HO]21.26-[Si(CH3)((CH2)3SO3H)O]1.8-[Si(CH3)((CH2)3Si(CH3)2O-)-O]14-Si(CH3)3}n (A) and {Si(CH3)3O[Si(CH3)HO]21.26-[Si ...
