Magnetic resonance study of a vanadium pentoxide gel
(SPRINGER, 2008)
In this work we report results from continuous-wave (CW) and pulsed electron paramagnetic resonance (EPR) and proton nuclear magnetic resonance (NMR) studies of the vanadium pentoxide xerogel V2O5:nH(2)O (n approximate to ...
Enhancement of Electrical Conductivity in Plasticized Chitosan Based Membranes
(TAYLOR & FRANCIS LTDABINGDON, 2012)
Plasticized natural macromolecules-based polymer electrolyte samples were prepared and characterized. The plasticization of chitosonium acetate with glycerol increased the ionic conductivity value from 3.0 x 10(-7) S/cm ...

About the SDS inclusion in PDMS/TEOS ORMOSIL: a vibrational spectroscopy and confocal Raman scattering study
(2011)
Organically modified silicates (ORMOSILs) are attractive materials due to their vast applicability and easy synthesis. The doping of these materials with sodium dodecyl sulfate (SDS) is interesting in the search for good ...
Thermal evolution of structures and conductivity of Pr-substituted BaZr0.7Ce0.2Y0.1O3-:δ: Potential cathode components for protonic ceramic fuel cells
(Royal Society of Chemistry, 2018-03)
A complete solid solution forms between the perovskite proton conductor BaZr0.7Ce0.2Y0.1O3-δ (BZCY72) and BaPr0.9Y0.1O3-δ (BPY) on synthesis by the Pechini method and high-temperature annealing. Phase fields of selected ...
