Experimental results
Article Abstract:
Research was conducted to examine the dielectrophoretic response of submicrometer particles as a function of electrolyte conductivity and composition, particle size and applied field frequency. Experimental results were compared with the classical theory of the dielectrophoretic force obtained from Maxwell-Warner interfacial polarization. Findings reveal that measurements of the dielectrophoretic nature of single submicrometer latex particles can be employed to uniquely characterize their dielectric properties.

Alcohol and proton transport in perfluorinated ionomer membranes for fuel cells
Article Abstract:
Four membranes containing different equivalent weight (EW) values were examined to clarify the transport mechanisms of alcohols and proton in perfluorosulfonated ionomer (PFSI) membranes for fuel cells. The density functional theory calculations of interactions between proton and alcohols revealed that larger alcohols have larger interaction energies and this relationship explains the proton transport efficiency by the Grotthuss mechanism.
